Greauxing Resilience at Home: A Regional Vision

Objective 3.1:

Maintain and preserve quality, resilient, affordable housing for frontline populations and existing residents.

The Need

The preservation of existing affordable housing stock is fundamental to promoting housing stability and avoiding the displacement of current residents, whether from gentrification and market pressures or physical risks like flooding. While producing new housing can help alleviate the demand for housing that is affordable and available to overburdened and underresourced residents, the pace of new construction usually lags far behind demand. Compared to creating new housing, the preservation of existing housing is also more cost-effective, requiring less resources in time and money. Therefore, prioritizing the preservation of existing housing — and helping its residents to stay in place — will be key to communities seeking to prevent the displacement of current residents and increase local resilience.

As other parts under this goal and the Regional Vision illustrate, creating new housing can also be challenging in the face of regulatory barriers, the rising cost of land, and exclusionary neighborhood mentalities like NIMBYism (or “Not in My Backyard”). Similarly, housing preservation can be complicated by several factors that decrease supply and/or affordability, including:See footnote 1  

  • Expiration: Government subsidies for housing are time-limited and do not exist in perpetuity. Project-based subsidies, where property owners agree to affordability and other types of restrictions in exchange for a capital subsidy, are limited in duration and non-transferable from one property to another. When these restrictions expire, owners — and particularly for-profit owners — are more likely to exit the affordability restrictions and operate properties as market-rate housing instead of affordable housing.
  • Deterioration: The physical quality of all housing will deteriorate over time, requiring the property to undergo ongoing maintenance and other operating or capital support to preserve habitability. Aging housing stock that do not pass physical inspections may lose government housing assistance, taking the property out of eligibility for affordable housing. Additionally, older properties may have structural issues — due to age and/or damage from flooding and extreme weather — and require accessibility upgrades, weatherproofing, and green or energy efficiency improvements.
  • Appropriations: Government-subsidized housing requires continuous funding from Congress. When federal appropriations fluctuate or do not keep pace with the rate of inflation, properties are at great risk for losing affordable units through expiration or depreciation. 

How to Make Progress on This Objective 

There are a variety of approaches that can be adopted by local policymakers to advance affordable housing preservation goals. The examples discussed below illustrate strategies that help to incentivize current or future property owners to maintain rents at an affordable rate, and/or empower mission-driven organizations and developers to more easily acquire lower-and moderate-cost properties. A few key approaches that other jurisdictions have adopted to preserve affordable housing include: 

  • Preserving naturally occurring affordable housing (NOAH);
  • Providing existing tenants with opportunities to purchase; and/or 
  • Supporting dedicated funding for anti-displacement programs.

Naturally Occurring Affordable Housing (NOAH)

In policy discussions, “affordable housing” generally refers to housing that has artificially been made low-cost through government subsidy programs, such as the Low-Income Housing Tax Credits (LIHTC) program.See footnote 2 However, in the United States, the majority of housing that is financially affordable for middle- or sometimes low-income households are non-subsidized housing, also known as naturally occurring affordable housing (NOAH).See footnote 3 While there is no uniform definition for NOAH properties in the housing industry, the term is commonly used to describe privately owned, existing residential properties that are rented out at cheaper rates due to the property’s age and other related characteristics. Common features of NOAH properties include: 

  • At least 15 years old. NOAH buildings are de facto affordable in part due to the age of the building stock. Most NOAH properties were built between 1940 and 1990. 
  • Classified as Class B or C rental buildings or complexes with over 50 units. Class B and C properties are terms of art in the housing industry commonly understood to refer to buildings with four or more rental units (i.e., a commercial property that generates income). Class B and C properties fall on the middle and lower ends of the spectrum, respectively, in terms of age, rent, location, amenities, and other attributes.See footnote 4 By comparison, Class A buildings tend to be more recently constructed, charge higher rent, and include amenities, such as pools and fitness centers.
  • Do not receive subsidies. NOAH properties can be rented at lower rates due to the physical characteristics of Class B and C buildings. Therefore, what keeps NOAH properties affordable are their below-market-rate features rather than a reliance on government subsidy programs. While many residents of NOAH housing hold tenant-based housing vouchers, the units themselves are not directly subsidized through government programs.See footnote 5 
  • Intended for low-and moderate-income households. NOAH units are more affordable for low and moderate-income (LMI) households, whose income range between 30 to 95 percent area median income.See footnote 6 By comparison, NOAH properties would be prohibitively expensive for extremely low-income households that have incomes below 30 percent area median income (AMI).See footnote 7 

Given the prevalence of NOAH properties as the most common type of “affordable” housing in the nation, their preservation can play a significant role in keeping the cost of rent affordable, enabling existing residents to stay in place. Parishes and municipalities can help keep NOAH properties affordable by working by partnering with mission-oriented developers interested in keeping rent affordable for existing residents and reducing the risk of displacement. For example, the City of Charlotte, North Carolina has developed public-private partnership models to ensure the continued existence of (former) NOAH properties.See footnote 8  

In 2020, the Charlotte City Council adopted the Pilot Naturally Occurring Affordable Housing (NOAH) Rental Subsidy Program, which was passed with unanimous bipartisan support from Charlotte’s City Council.See footnote 9  Under the Pilot NOAH Program, the City of Charlotte has pledged to work with developers of NOAH properties to preserve long-term affordability for renters earning between 30 and 80 percent AMI, or roughly $25,250 annually for a family of four in Charlotte.See footnote 10 The city helps developers acquire and preserve NOAH properties by providing them with an annual rental subsidy for a minimum of 20 years — or the duration of a deed restriction — at an amount not to exceed the city’s annual property tax bill.  The subsidy is then used to cover the difference between what an LMI household can afford and the rent on the unit. In exchange, participating developers and owners (if a property is owned by a separate entity from the developer) agree to affordability restrictions to limit rent growth, and to make units affordable to residents at specific income levels as the units become available through natural turnover. 

Opportunities to Purchase 

Several jurisdictions across the country have adopted some form of a “right of first refusal” (or “first right purchase”) law that provides tenants, nonprofits, housing agencies, or other mission-driven organizations with an advance period of time to make a purchase offer for a property. These so-called first refusal rights may be triggered under certain conditions, such as during the sale of a multifamily building, or when affordability restrictions on a building expire and the owner no longer wishes to participate in a subsidy program.See footnote 11  

Right of first refusal laws can provide eligible buyers of a property — including tenant associations, nonprofit developers, and local government agencies — with a valuable window of time to organize, produce financing, and make an offer on the property before competing market-rate developers are able to bid. In this way, right of first refusal policies can help prevent the conversion of lower-cost or subsidized housing into market-rate or luxury properties, all the while helping tenants become homeowners. Even if the tenants are ultimately unable to acquire the property, asserting the right of first refusal provides existing residents with additional time to locate new housing or access new housing services, thereby improving their chances of seeking new affordable housing, if not preventing their displacement.

In 1980, the City of Washington, D.C., adopted the nation’s first Tenant Opportunity to Purchase Act (TOPA) to allow tenants the right of first refusal.See footnote 12 Under TOPA, tenants have the right of first refusal to match competing offers for the sale of subsidized housing or private rental housing. Tenants may purchase units individually (transferring them into condos) or collectively as a tenant association and in partnership with a developer. Between 2002 to 2013, TOPA has helped to preserve over 1,400 affordable units in the District.See footnote 13  

Anti-Displacement Programs 

Like renters, existing homeowners are also at risk of displacement in quickly growing neighborhoods. When home values increase due to population shifts due to flooding and extreme weather, rising demand, and/or physical renovations (among other factors), property taxes will also rise, placing existing residents at risk of displacement if they are unable to afford the increase. 

In order to help current homeowners stay in place, localities should consider collaborating with the private sector to support or create programs that provide financial support to homeowners in need of assistance. For example, the Anti-Displacement Tax Fund (ADTF) program in Atlanta, Georgia, provides financial assistance to eligible homeowners to offset the cost of rising property taxes, helping existing residents in some of the fastest-growing neighborhoods of Atlanta to stay-in-place and avoid displacement.See footnote 14 Established in 2017 and funded through private donations, ADTF provides a grant to existing homeowners for up to 20 years. The program specifically targets homeowners who have an annual household income below 100 percent of the area median income (AMI), and have lived in a home within the program’s designated geographic boundaries in the Westside community since at least March 2017. In 2020, Atlanta’s mayor issued an administrative order directed at the city’s development agency to implement a city-wide anti-displacement fund, using $4.6 million of the city’s $28 million housing trust fund to offset the rising cost of property taxes for residents who may experience a heightened risk of displacement.See footnote 15

Parishes and municipalities could also consider taking other proactive measures. The City of Austin provides one example of taking a comprehensive approach to addressing displacement, using a combination of planning, legal, and funding strategies to help residents stay in place. In 2014, the city created an Anti-Displacement Task Force, which led to a series of recommendations, the development of a Displacement Prevention Strategy, and the creation of the position of Community Displacement Prevention Officer.See footnote 16 Later, the city adopted a Tenant Relocation Assistance ordinance, which requires developers to provide sufficient notice before tenants can be evicted, and directs the city’s Neighborhood Housing and Community Development agency to establish a Developer Fund for Tenant Relocation Assistance. Finally, Austin’s comprehensive transit development plan, Project Connect, includes a $300-million investment toward anti-displacement measures that include transit-oriented development and affordable housing along new routes in the transit plan. To inform the city’s anti-displacement efforts, agencies leading Project Connect partnered with the city’s Department of Housing and Planning to create a series of anti-displacement maps that outline the displacement risk of various neighborhoods along new planned transit routes.

Crosscutting Considerations and Practice Tips

When identifying strategies to preserve existing affordable housing in urban localities, decisionmakers may consider the following considerations and practice tips that apply to one or more of the strategies described above: 

  • Encourage collective action by residents
  • Promote housing literacy
  • Collaborate with mission-aligned developers

These tips are based on priority implementation best practices and considerations most relevant to this specific objective and do not present an exhaustive list for regional and local planners and policymakers. In addition to this objective, decisionmakers should, at a minimum, also refer to Goal Five for crosscutting considerations and practice tips including structuring equitable and inclusive community engagement processes and evaluating opportunities to build public-private-nonprofit-community partnerships. 

It is important to acknowledge that every jurisdiction will be starting from a different place and have a unique local context and needs, among other factors. Therefore, these considerations and practice tips could be adopted individually, collectively, or not at all. 

  • Encourage collective action by residents:  Tenants who negotiate together have greater bargaining power than those who act unilaterally. Local governments can pass laws that create right of first refusal opportunities to residents, as well as partner with local tenant associations, housing groups, and legal assistance programs to help tenants understand their rights. Right of first refusal policies are most effective at helping residents stay-in-place when communities already have a network of engaged residents who understand and share common housing priorities, are active in housing policy and community organizing, and are able to negotiate with a unified voice. For example, when residents invoke their TOPA rights, it is important that tenants agree on a common goal: whether to assign their right to purchase to a for-profit developer and move out (in exchange for a cash buyout), or continue to fight for their right to purchase the property and negotiate for lower prices.

  • Promote housing literacy: Local governments can help residents better understand their rights by distributing factsheets and other public outreach materials via different media platforms and locations (public meetings, libraries, social media), diverse formats (both electronic and hard copy, for residents who may not have access to the internet), and in languages that are inclusive of the local demographic. Residents who know their housing rights are better equipped to advocate on their own behalf, enabling them to have greater control over their housing conditions. Having an awareness of key strategies like the right of first refusal, or the resources to help navigate the intricacies of these policies, are critical to ensuring that residents are able to access already-available tools that can help them stay-in-place and keep their existing housing affordable.

  • Collaborate with mission-aligned developers: Parishes and municipalities should consider ways to partner with mission-aligned developers who share similar goals for increasing the availability of housing for families at all income levels, particularly those that are underresourced. Many preservation strategies require collaboration not only among current residents and community stakeholders, but also with and among certain kinds of developers. Affordable housing developers frequently take on multiple roles in the affordable housing lifecycle, adopting not only the role of the developer, but also that of a landlord and property manager. In many cases, residents may find themselves partnering with nonprofit or mission-aligned developers that are willing to make a positive, if not below-market-rate, return on investment. For example, in Washington, D.C., tenants who participated in the city’s First Right Purchase program under TOPA can assign a portion or all of their rights to a developer (either nonprofit or for-profit), in exchange for the developer’s commitment to rehabilitate and maintain the units at affordable rates for a prescribed period of time.See footnote 17 In Charlotte, North Carolina, one of the first developers to participate in the Pilot NOAH Subsidy Rental Program was a mission-aligned, for-profit developer that sought a mix of public and private financing sources to acquire and preserve existing NOAH properties.
