LIHTC Apartments vs Inclusionary Housing and BMR Units
LIHTC apartments, inclusionary housing, and BMR units can all be advertised as affordable housing, but they do not come from one national program. LIHTC is based on the federal Low-Income Housing Tax Credit under Section 42 of the Internal Revenue Code. Inclusionary and below-market-rate programs are usually created by a city, county, or other local government through zoning rules, development requirements, regulatory agreements, or local housing policy.
For renters, that distinction matters because the income limits, rent restrictions, application system, lottery rules, and length of the affordability restriction may be different even when two apartments are in the same building.
LIHTC Starts With a Federal Tax Credit
The Low-Income Housing Tax Credit gives owners of qualified residential rental buildings a federal tax credit when the project satisfies Section 42 requirements. State or local housing credit agencies allocate credits and monitor compliance.
The federal government therefore establishes the basic tax-credit framework, while housing credit agencies handle important allocation and compliance responsibilities at the state or local level.
LIHTC is not a federal rental-assistance payment made directly to every tenant. The credit supports the development and operation of qualified low-income rental housing, and the property must maintain the required low-income units and rent restrictions.
Inclusionary Housing Comes From Local Development Rules
Inclusionary housing usually starts somewhere else: local land-use or housing policy.
A city may require or encourage a developer to include affordable apartments when constructing a larger market-rate development, receiving additional development capacity, rezoning land, or participating in another local development program.
The exact structure is local. New York City's Mandatory Inclusionary Housing, for example, requires permanently affordable housing in qualifying developments within designated areas. Other jurisdictions use different set-asides, affordability levels, incentives, or compliance periods.
The broader inclusionary housing system in the United States therefore cannot be reduced to one federal eligibility formula.
BMR Is Usually a Local Housing Label, Not a Separate Federal Tax Program
“BMR” usually means below market rate. Local housing agencies and developers use the term for homes or apartments whose rents or sale prices are restricted below ordinary market levels.
A BMR unit may be created through an inclusionary housing ordinance, a development agreement, local financing, a density program, or another affordability requirement.
That is why “BMR” does not automatically tell you which federal program applies. A BMR apartment may have no LIHTC restriction at all, while another property may carry both BMR or inclusionary requirements and LIHTC restrictions.
The rules for below-market-rate housing units depend heavily on the jurisdiction and the specific program attached to the property.
The Agencies Behind the Programs Are Different
For LIHTC, the IRS administers the federal tax provisions and housing credit agencies allocate credits and monitor Section 42 compliance. Owners must maintain records and comply with the requirements attached to the tax-credit allocation.
For inclusionary or BMR housing, a local department is more likely to control the affordability program. Depending on the city, that may be a housing department, planning agency, mayor's housing office, redevelopment authority, or another local entity.
This affects where you verify the rules. A tax-credit property may point you to the property manager and state housing finance agency, while a BMR listing may direct you to a city housing portal or local affordable-housing office.
There Is No Single National Application Portal for LIHTC Apartments
LIHTC does not operate through one federal waiting list where a renter submits a single application for every tax-credit apartment in the country.
Applicants generally apply through the property owner, management company, or a housing application system used for that particular development. The household then has to satisfy the income and occupancy requirements applicable to the unit.
Two LIHTC properties in the same metropolitan area can therefore have separate applications, separate waiting lists, and different availability.
Inclusionary and BMR Housing May Use a Central Local Portal or Lottery
Some local programs organize affordable units through a citywide portal, lottery, or agency-managed waiting list.
New York City uses NYC Housing Connect for many affordable housing opportunities. In Washington, D.C., current rules provide for Inclusionary Zoning and certain Affordable Dwelling Units to be filled through a Department of Housing and Community Development lottery or agency-provided waiting list. San Francisco uses local systems for many BMR opportunities.
Those are local systems, not national rules.
A renter in another city should not assume that the same portal, lottery sequence, preference system, or documentation rules apply. The local program determines how applicants reach the available units.
This is also why affordable housing lotteries need to be read as local opportunities rather than one nationwide application program.
A Lottery Does Not Mean the Unit Is Not LIHTC
Application method and financing source are separate questions.
An apartment can be financed with LIHTC and marketed through a local affordable-housing lottery. If the property also participates in an inclusionary or BMR program, the city may require the unit to be advertised or leased through its own system.
Seeing a unit on a municipal lottery portal therefore does not prove that it is “only” inclusionary housing. The project documents may show additional LIHTC restrictions behind the same apartment.
Do Not Assume the Income Limits Are the Same
An LIHTC property and a local BMR property may both describe units using percentages of area median income, but the numbers should not be treated as interchangeable.
Section 42 allows different federal income-test structures, including the 20-50 test, the 40-60 test, and the average-income test. A project's elected test and unit designations affect which households can occupy its tax-credit units.
A local inclusionary program can establish its own affordability bands. One city might require units at several income levels, while another might target a narrower range. Local programs can also use household-size assumptions and rent-setting methods that are not identical to Section 42.
So a household that qualifies for an apartment advertised at one local BMR income level should not assume it automatically qualifies for every LIHTC property using a similar-looking AMI percentage.
LIHTC Has a Federal Minimum Affordability Structure
Section 42 includes a 15-year compliance period and an extended-use requirement.
For projects subject to the extended-use rules, the extended low-income housing commitment generally continues until at least 15 years after the end of the 15-year compliance period, producing a federal framework that can extend affordability to at least 30 years from the start of the compliance period.
That is a minimum federal framework, not a universal expiration date for every LIHTC property. The housing credit agency, recorded agreement, state law, financing documents, or other restrictions may require a longer period. Section 42 also contains specific rules and exceptions affecting termination of the extended-use period.
Local Inclusionary Affordability Can Be Shorter, Longer, or Permanent
There is no national inclusionary-housing affordability period.
The local ordinance and recorded regulatory documents control. New York City's Mandatory Inclusionary Housing is an example of a program requiring permanent affordability for the applicable affordable housing.
Another local program may use a defined number of years instead. The correct period has to be checked against the specific jurisdiction and the project's recorded restrictions.
This makes one of the most common comparisons misleading: “LIHTC lasts 30 years and BMR lasts forever.” Neither statement works as a national rule. LIHTC can carry restrictions beyond the federal minimum, while BMR and inclusionary periods vary by local program.
A Single Building Can Be Both LIHTC and Inclusionary Housing
Affordable housing programs are often layered.
A developer may receive LIHTC financing while also agreeing to local inclusionary restrictions, receiving another public subsidy, or participating in a local BMR program. The same development can therefore be subject to more than one affordability agreement.
When restrictions overlap, the property does not get to choose whichever rule is easiest to follow. The owner must comply with the requirements that apply to the unit and project.
For an applicant, the practical effect can be additional eligibility checks or a rent ceiling that reflects more than one program.
The Most Restrictive Applicable Rule Can Matter
Layered projects require careful reading because federal and local restrictions may not use identical income categories, household assumptions, or rent calculations.
Suppose a unit is designated under Section 42 and is also subject to a local inclusionary agreement. The owner may need to confirm that the household satisfies both sets of restrictions applicable to that unit. A household that fits one program's income band may still fail another restriction attached to the apartment.
The same principle applies to rent. A project may have to satisfy the LIHTC maximum gross rent rules and a separate local affordability requirement. The controlling rent cannot simply exceed one restriction because the other program would have allowed it.
BMR Homeownership Is a Different Category
Some cities use “BMR” for affordable homes that are sold rather than rented.
Those programs can include resale-price controls, owner-occupancy requirements, buyer eligibility rules, appreciation formulas, or restrictions on refinancing. Those are not LIHTC rental rules.
Section 42 LIHTC is fundamentally a residential rental housing credit. A local BMR ownership program should therefore be evaluated under its own homeownership rules rather than being compared as though it were another type of LIHTC apartment.
How to Identify Which Rules Apply to an Apartment
Do not rely only on the words “affordable,” “BMR,” “tax credit,” or “income restricted” in an advertisement.
Before applying, identify:
- the name of the property and management company;
- whether the unit is LIHTC, inclusionary/BMR, or subject to both;
- the agency that monitors the affordability restriction;
- the income limit assigned to the specific unit;
- the rent or maximum gross-rent rule that applies;
- whether the application goes directly to the property or through a local portal or lottery;
- and whether another subsidy is attached to the unit.
Those answers tell you far more than the general label on the listing.
Which Program Is Better for an Applicant?
Neither structure is automatically better. The useful comparison is the actual apartment you can apply for.
An LIHTC property may offer a direct property application without waiting for a citywide lottery. A local BMR program may place many developments in one searchable portal. One unit may fit your income while another does not. A layered LIHTC and inclusionary unit may give you access to a particularly restricted rent but require you to satisfy multiple eligibility rules.
For a renter deciding where to apply, the safest approach is to treat LIHTC and inclusionary/BMR opportunities as separate pipelines unless the listing or program documents show that the same unit participates in both.
