Key Words: Affordable Housing, Cities, Urban Development 2 1. Introduction Peru, like most other countries in the region, urbanized quickly in the second half of the twentieth century, going from just over 50 percent urban in 1965 to almost 80 percent urban today. Peru’s urban population continues to grow at a rate of 1.72% per year, slightly higher than the Latin American average of 1.49% per year.i The urban population in Peru is divided among a system of 32 cities. Despite the high concentration of urban population in Metropolitan Lima (about 50 percent of urban dwellers and 30 percent of the total population), about ten million urban dwellers are distributed across smaller cities. As a result of the rapid urbanization over the past decades, much of it unplanned and informal, cities across the country are facing significant constraints and challenges in transforming into livable and productive places. With urbanization and city growth, citizens’ demand for more affordable housing, employment, urban infrastructure and social services rises. This creates technical and financial challenges for national and local governments. Despite its significant efforts to promote the supply of new housing, for example through direct subsidies and housing loans, Peru still has one of the largest housing deficits in Latin America (surpassed only by Nicaragua and Bolivia). According to World Bank estimates, while the national government has invested USD 3.3 billion on its housing programs between 1999 and 2014, the estimated value of the 1.3 million new housing units needed to close the housing gap in Peru (without considering the qualitative deficit) is USD 30 billion. This demand represents both a public policy challenge for national and local governments and an enormous potential to leverage the existing construction industry and financial institutions to generate additional housing and spur market growth. This report applies a housing value chain analytical framework to identify and analyze the bottlenecks behind the lack of formal affordable housing in Peru. Using the example of Peru and drawing upon good practices in other countries, we argue that there is plenty of room to increase the impact of housing policies by using the methodology utilized in this report to improve their design and implementation. The methodology applied includes a literature review, interviews with key public and private stakeholders, legal and institutional analysis, data compilation and analysis, workshops with national government officials in the Ministry of Housing, Construction and Sanitation (MVCS) and private sector representatives, and field work in the metropolitan areas and districts of four cities (Lima, Chiclayo, Huancayo, and Moyobamba) selected on the basis of diversity of population size and geographic location. 3 In the first section of the paper we describe the analytical framework we used for the identification of the main bottlenecks affecting the production of formal affordable housing in Peru. In the next section we describe the main findings of our diagnostics and we suggest possible ways of using the housing value chain analytical framework to improve the design and implementation of housing policies. 2. Methodology: The formal housing value chain analytical framework For the purposes of this study, we refer to formal housing units as those that have (i) clear, secure and transparent property rights that make the real estate assets fungible (for example, allowing them to be pledged as collateral for a mortgage loan); and (ii) sound structure that has been built in compliance with local planning standards and construction codes and permits. The formal housing value chain summarizes the coordination required between the public and private sector in seven interdependent steps required in order to produce formal housing units. This breakdown is particularly useful considering the complex reality behind the housing production system. For example, we found that in Peru the housing value chain involves the active participation of 40 types of actors (private and public) within the rules set by 52 pieces of legislation cutting across different levels of government (district, city, province, national). The seven interdependent steps of the value chain are: planning, land availability, urban infrastructure, project appraisal and licensing, urbanization, edification and marketing and finance. Below is a brief description of the activities included in the value chain: a) Planning includes policies, strategies and planning instruments, housing programs, and urban regulations particularly related to zoning and land management, the model defined to guide the development of the city, the information systems that support the city planning activities, the location of social housing projects, the definition and compliance of building standards among others. b) Land availability includes the identification of available land according to the existing urban standards, the assessment of their value and the identification of their ownership, based on the estimated demand for land for housing projects. It also includes management, acquisition, regularization, titling and registration of such land. c) Urban infrastructure includes the planning and construction of basic urban infrastructure (roads, water pipes, sewerage, and electricity) required to develop a part of the city that incorporates social housing projects. 4 d) Project appraisal and licensing includes meeting the requirements and obtaining the permits and licenses needed to develop a real estate project, as well as performing the financial analysis to determine its feasibility. e) Urbanization includes the preparation of the land for construction, the installation of the infrastructure connections for the project, the budgeting for the construction and the delegation of the supervision roles. f) Edification includes the construction of the housing units. g) The marketing and finance includes marketing and project financing for developers and for end-users (e.g. construction finance and mortgage financing). The production of formal housing units is adequate when, along all the steps of the housing value chain, there are: (i) clear and enforceable rights and obligations for all agents involved, (ii) balanced incentive mechanisms for market participation both form buyers and sellers and (iii) active coordination and cooperation mechanisms between all levels of government and the private sector. When these elements are not in place, either in part or throughout the whole housing value chain, two major developments take place: First, the production of formal housing units is scarce and the houses that are constructed tend to be far too expensive for most people. According to our estimates, the formal annual supply of housing can only serve 30% of the demand of housing generated by the new households that are formed in the country every year. In addition to that, given current market conditions, only 45% of the households in Peru (with both family members working) have the income levels necessary to be able to obtain a mortgage to buy the cheapest housing unit available in the market. This means that in practice, only the high-income segments of the population have access to formal housing units, while the majority of families end up finding a solution to their housing needs in the informal market, exposing themselves to many risks in their transactions with land-traffickers. According to our estimates, 8 out of 10 of the new houses that are built in urban areas can be classified as informal as they do not comply with existing regulations. This, however, is not a recent phenomenon and thus, as shown in Figure 1, the share of existing housing units with a property title in the country is substantially low even after conducting a large formalization program in the nineties. 5 Figure 1: Housing units with property title Total 36% V 56% IV 46% III 26% II 25% I 17% 0% 10% 20% 30% 40% 50% 60% By quintile of income Source: INEI (2009). Second, the effectiveness of public interventions around housing (for example, those related to the provision of public services, urban infrastructure and other services such as education, health, security and waste management) is significantly diminished. As a result, the costs of accommodating the urban growth and the housing gap continue to increase. Table 1 below illustrates the informal housing value chain and the actions taken at each step, which can be contrasted with the formal housing value chain used in this study. Table 1: The informal housing value chain Components of the formal Description of how each component of the housing value value housing value chain chain operates in the informal world Planning Limited. Informal housing units then to be located at the urban periphery, sometimes even in risk areas. Land availability Frequently related to an illegal occupation, informal housing units are often subject to insecurity of tenure due to the lack of legal title. 6 Urban infrastructure Poorly serviced by infrastructure networks and public services such as roads, power, piped water, sewage / drainage, among others. Project appraisal and Lack of compliance with regulations but overall a cheaper licensing alternative for households. Urbanization Lack of coordination with local authorities regarding conditions for mobility and livability. Edification Self – designed, self – built and incrementally improved over a long period of time. Marketing and finance Households generally finance the acquisition or construction of their informal dwellings through family / group savings and / or loans from informal lenders. 3. The housing challenge in Peru We applied the formal housing value chain analytical framework to the case of Peru using secondary data and by conducting field-work in 4 cities of different sizes (Lima, Huancayo, Moyobamba and Chiclayo) to draw general conclusions at the national level and formulate specific proposals to improve the production of formal housing. We found the reality in Peru to be consistent with that of other developing economies in Latin America, Asia and Africa: The production of formal housing is insufficient to eliminate the quantitative and qualitative deficits, let alone to supply housing solutions to the new households that are being formed in the country every year. While the quantitative deficit is centralized (9 regions concentrate 80% of the quantitative deficit), the qualitative deficit is more decentralized (81% of the qualitative deficit is concentrated in 14 regions). The data indicate a geographic bias in the supply of housing—and housing finance— across the country. While some regions are overrepresented like Lima, La Libertad and Ica, others are underrepresented, such as Piura and Junín. 7 While the demand for housing is high, the financial capacity of the population is low (even considering the government subsidies available through MiVivienda or Techo Propio). Only 55% of the households that would like to purchase a housing unit can actually afford one, providing that they can finance it through the formal market. However, 70% of the income of these households is either informal or irregular, which complicates further the access of the families to long-term traditional housing finance products. For the developers, building housing units for the higher income segments is 125% more profitable than targeting the lower-income segments of the population. The absence of adequate urban planning and regulation policies is generating urban sprawl instead of promoting urban renewal and densification, and thus increasing dramatically the cost of service provision for local governments. The production of sufficient and affordable formal housing units could be improved in Peru by taking on board a series of general and specific actions across the following legal, institutional, financial and operational areas of the housing sector. a. General actions Creation of actionable knowledge to inform the housing sector. In Peru, as in many developing countries, for most households, purchasing or building a house is their single largest investment and the preferred method of intergenerational wealth transfer. Despite its importance for citizens’ well-being, there is very little consistent and reliable data and knowledge about the housing sector. Determining the size of the housing gap in a country is in itself a complicated task; the absence of data makes the challenge even harder. In Peru as in most developing countries, the housing gap estimates vary depending on the type of deficit being discussed (quantitative or qualitative, formal or informal) and on a compendium of different sources of data held by different public and private actors. According to the IADB, Peru’s housing deficit is ranked third in the LAC region1, behind Nicaragua and Bolivia (Figure 1). According to our estimates, the requirement for new housing units in Peru is approximately 1.3 million units when factoring in the 1 Banco Interamericano de Desarrollo. (2012).

Washington, D.C. 8 quantitative deficit from the 2007 census data and the estimation of the formation of new households through 2015. This figure does not include the existing qualitative deficit in the country.

Note: The Inter-American Development Bank uses a definition that includes both quantitative and qualitative deficit to determine the percentage of the population with adequate housing. Without adequate land registries that are connected with the national registry, local governments cannot manage the urban expansion of their districts, let alone increase their property tax collection. Without an inventory of state-owned real estate assets, the government cannot assign the best use to its assets or make them available to the promotion of social housing programs. Finally, without a system of information regarding the housing market (for example, tracking housing prices, housing starts, etc), the government cannot prioritize and determine the effectiveness of their policies; and businesses and people cannot make investment decisions consistent with their risk preferences. Design and implementation of an articulated housing strategy that provides citizens with housing options that are superior to informality. Despite substantial investments in demand-side housing programs, which have mostly been implemented through up-front subsidies (Techo Propio) and credit programs operated by Fondo Mi Vivienda, the programs have had only a limited ability to promote affordable housing 9 90% construction; there is an apparent disconnect within the public agencies that implement housing-related State programs. In addition to that, while the success of housing policies depends highly on the performance of local governments, the interaction and coordination mechanisms between the national and local governments are not operating properly. We have identified the following five components that could be further developed to contribute to the articulation of a successful strategy for housing promotion. - The definition of clear national guidelines and the development of tools to assist local authorities to manage the growth of their cities. Gaps in these tools and guidelines have de-facto left the definition of city growth and expansion to the private sector (both formal and informal). - The clarification of roles of the various state actors who have a part to play in the value chain of formal housing production. Currently, some of these roles are inconsistent, incomplete or redundant, which affects the consistency and efficiency of the actions of the national government. - The definition of the rights and obligations of the private actors involved in the housing market that would allow cities to take advantage of modern financing mechanisms, such as land value capture, to improve their urban infrastructure. - The streamlining of the incentives that the government provides for the construction and purchase of homes to increase their effectiveness to stimulate the involvement of the private sector in the construction of housing units for the low-income segments of the population. Technical and financial empowerment of city governments. The effectiveness of Peru’s housing policies is also constrained by the existing legal and institutional framework and the decentralization process. Most of the existing norms were designed to support the decentralization policy of the early 1990s, with the first efforts on land administration. The framework established the distribution and hierarchy of roles and responsibilities between the national, regional and municipal levels, with planning instruments designed to align municipal and regional actions with national directives. However, in practice, when the competencies related to land administration were officially transferred to the regions and local governments (between 2009 and 2013), the change was made without mechanisms in place to ensure the regions and local governments were technically and financially ready to 10 take on these new competencies. In addition, monitoring and evaluation mechanisms were not established prior to the transition. As a result, Peruvian cities cannot leverage the (re)development of residential districts, public infrastructure, transport assets, and access to lower cost public service delivery to support the sustainable development and growth. Without land management tools and policies, local governments lack the financial and technical capabilities and the incentives to plan the growth of their cities, based on the expected demand for housing and the investment in the accompanying infrastructure required. b. Specific actions Planning The national government could introduce incentives and targeted programs to support the efforts of local governments related to urban planning. With a better definition of the roles and pattern of interaction between the national and local governments, based on a typology that recognizes the heterogeneity of their technical and financial capacities in urban planning and management, it would be possible to harmonize urban policies, respecting the autonomy of local governments as envisaged in the decentralization law. Currently, while it is possible to find small cities in Peru like Moyobamba with a population of 56,000 that have updated planning instruments, there are large cities like Chiclayo that are still operating with the city planning instruments from 1992 (see Figure 2). - Figure 2: Planning instruments in Peru Chiclayo is an intermediate city with a population of 600,000. The updated planning instruments developed in 2010-2011 have not been officially approved and thus the province still operates with planning instruments from 1992. 11 Moyobamba is a small city with a population of 56,000. The city has updated planning instruments. Instead of neglecting previous efforts, the new administration is building on the efforts of the preceding one. Source: World Bank, 2015 Some products or instruments that the national government could offer the local governments are: - Partial or total funding for the elaboration of urban planning instruments. - Technical assistance and / or certifications in both urban planning and control and collection of property tax. - Conditional funding for investment on urban infrastructure and/or housing programs like the HOME program created in 1990 in the U.S by the Department of Housing and Urban Development. This program, that was originally designed to promote social housing supply in a decentralized context, has a budget of USD 1 billion that could be accessed by local governments upon the completion of certain conditions related to the provision of social housing. The introduction of an obligation or incentive to include a minimum percentage of social housing in the construction of new housing projects could boost the production of social housing. Due to the high cost of serviced land for housing development and other factors, developers opt to build housing for higher income segments in order to maximize their profitability. The introduction of obligations and incentive mechanisms for the construction of social housing, such as the minimum quota in real estate projects, transfers of land, compensation with edification rights, among others, could be used to address this issue. These approaches have been successfully utilized in several countries, including Colombia, the United States, and Mexico, among others. The introduction of land management instruments could allow local governments to promote densification and at the same time generate resources to fund the provision of services and/or the additional urban infrastructure required. Currently, as shown in Table 2, the densities in Peru, and even in Lima, are low according to international standards. By encouraging the use of zoning and mixed uses as land management tools, it would be possible to increase the profitability of real estate projects and encourage the production of 12 social housing. In addition, this approach would help reduce the high costs of provision of basic infrastructure and economic and social segregation that occurs when low-income families choose to settle in areas far from urban centers because the peri-urban expansion areas are the only affordable option for housing. Higher densities could also decrease the demand for new land for housing projects. According to our estimates and the ranges of densities defined by the Reglamento de Acondicionamiento Territorial de Desarrollo Urbano (RATDU), closing the housing gap could require from 8,831 hectares (with high density) to 47,310 hectares (with low density) across Peru’s cities (Table 3).

Land availability and urban infrastructure In order to increase the availability of public land for social housing purposes, the country would benefit from the use of a broader and unique definition of available land earmarked for housing. While for some institutions, it is sufficient to find a plot of land legally owned by the State, others require evidence that the public services, such as water and sanitation, are able to be connected to the proposed plot. Finally, the minority of institutions look for plots of land that have both clear ownership and the public services already connected to the plot; however, these factors increase the price of land and therefore increase the price of the housing units being constructed. For example, during the field work we carried out in the case study cities, we found that one plot of serviced land could cost up to 7 times more than one without services within a 6 km. radius. The institutional setting in Peru could be improved to increase the government’s ability to manage land efficiently. For example, the government cannot perform the following functions under its existing legal framework: to act as a land bank that is legally empowered to acquire or manage by delegation public and/or private land for housing projects; to act as a real estate bank that is able to acquire private properties for the development of urban regeneration or housing projects; to act as a real estate developer capable of partnering with private companies for developing housing projects and administering the public housing stock, articulating them with the subsidies program. Such institutional framework could be implemented either at the national or local level or through a combination of both. The Korean and Colombian experiences are both good examples of the creation of agencies at the national level to perform these functions. Some examples of local agencies that perform these functions at the local level could be found also in Colombia. In addition to that, the institutional setting 14 does not have appropriate rights of preference and acquisition mechanisms that could be used by the State to acquire private land in areas that have been declared to be of interest for housing projects. A similar set of institutional arrangements and competencies are also needed for local governments to be able to perform these functions locally. The legal framework for local governments could be improved by introducing the tools they need to generate revenue from the serviced land that exists in consolidated urban areas to help them finance the cost of basic service infrastructure. Some municipalities or State-owned agencies own limited amounts of land, which they can strategically sell or develop in order to generate resources they can then use to finance infrastructure. In other cases, not much land is owned by the State but still the capacity of planning and regulating land use within their administrative boundaries remains the responsibility of the local governments. In these cases, land value capture instruments such as changes of land use (through land use conversion or change in zoning and property taxation) or development rights (authorization for higher densities or greater floor area ratios) could be tools that the local governments could use to generate revenues that could finance urban infrastructure. Within the Ministry of Housing, Construction and Sanitation, improvements could be achieved through better coordination of its functions with a view to generate and manage serviced public land. On one hand, the provision of basic services to identified plots of lands designated for housing projects could be managed more efficiently. On the other hand, an improved allocation system for investments of the Ministry could introduce incentives that facilitate the alignment of local government actions to national priorities and help stimulate the production of more affordable housing to meet the demand. Feasibilities and Licenses, Construction, Marketing and Finance The roles of the Ministry of Housing, Construction and Sanitation and Fondo MiVivienda (FMV) in the design, implementation and monitoring of housing policy could be clarified. This would minimize duplication of efforts and / or contradictory actions. 15 The existing subsidies programs, FMV and Techo Propio, could be merged and calibrated to improve their efficiency and ability to reach the target population. Currently the two subsidies programs operate with different legal, institutional and operational frameworks although they pursue the same objective. For example, seven pieces of legislation govern the operations of MiVivienda while other eight different pieces of legislation apply to Techo Propio. Given these conditions, neither of these programs has been successful in reaching the lowest income population segment. Table 4 below illustrates the targeting of subsidies and the differences in the subsidy amounts by program and by income quintile.

In addition to that, MiVivienda offers a subsidy to the interest rate. Source: MVCS. The regional and municipal governments’ engagement as strategic partners in the promotion of social housing is still at an early stage. With clearer roles, the provision of relevant technical assistance and conditional funding for investment on urban infrastructure or housing projects, an improved coordination and cooperation between the national and local governments could be achieved. The platform for innovation in the housing sector could be improved. New housing solutions (different from the traditional purchase with a mortgage – such as rental or leasing options) and building techniques and use of new materials (different from the traditional brick and cement block) need to be introduced in the market. Currently, only 6.6% of the occupied housing units are rented in Peru, far below the regional average (16.9%) and the EU 16 average (26.5%). In addition to that, new financing products for real estate developers should be developed in order to avoid forcing the families to finance the housing projects through higher initial payments or interest rates. Currently, families fund the developers through higher costs, equivalent to a 13.9% increase in the monthly payment of their mortgage due to the existing regulations defined by the financial regulator. Concluding Remarks The housing deficit in Peru mainly affects the poor and contributes to the proliferation of illegal settlements in urban areas, which are generally located in unplanned neighborhoods, lack titling, and have limited access to basic services and reasonable connectivity with the economic centers. This paper has described some of the constraints to the supply of affordable housing that were identified, including cumbersome and inefficient regulation, lack of access to land, infrastructure (for new housing), and infrastructure and construction finance. Our analysis suggests three strategic actions the Government of Peru could take to support its efforts to strengthen the housing market and better enable the production of social housing, including the need for: (a) establishment of a national housing policy to align public and private actors under a common framework; (b) creation of robust information systems to inform decision-making with regard to the sector – such as transparent information on the housing sector, national inventory of land, and functioning cadasters - to improve the effectiveness of government interventions and targeting of programs; and (c) decentralization of government housing programs, subsidies and efforts to build capacity for urban planning and land management at the local level, with support from the national government. Additional challenges to urban planning and land use include limited capacity at the local level and the ineffective use of planning instruments and ad-hoc urban development, primarily due to economic and political pressures. Very few district-level municipalities have the capacity to develop and implement urban development plans, and the existing plans are often obsolete or inconsistent.1 There are overlapping spheres of authority amongst local and national government agencies regarding critical components of urban land development especially for land use planning (or legal approvals, regulatory oversight, and timing and amount of capital funds), dispersed decision-making, opaque approval processes, etc. As a result, cities grow in an uncontrolled and unplanned way with difficulties in providing services and housing adequately and proportionately to the different segments of the 17 population. The current framework is insufficient for cities to advance their local economic development initiatives effectively. Furthermore there is a lack of alignment of incentives between the sectors, the municipalities and developers (and investors), and therefore missed opportunities of leveraging this type of alliance for mixed land use and increasing the supply of affordable housing. To articulate national urban policies and housing in a decentralized environment, it is critical to gradually incorporate local governments in implementing policies of both urban planning and land management and promotion housing and create incentives for decision-making in line with national policy. In such a context, the role of the national government should gradually converge to one which predominantly sets general policy guidelines and transfers partial functions and powers of enforcement, supervision and coordination of national policy to local authorities (eg, regional committees). In the medium term, the national government could consider transferring funds directly to cities that have high housing deficits to implement the national programs locally. In addition, incentives aimed at activating the investment decisions of the private sector should be adapted to local realities in order to be more effective.
