Section 42 housing refers to a specific provision of the United States Internal Revenue Code that established the Low-Income Housing Tax Credit (LIHTC). Created under the Tax Reform Act of 1986, Section 42 is the federal government's primary tool for encouraging the private sector to develop and rehabilitate affordable rental housing for low-income households. Unlike traditional public housing or voucher programs, Section 42 relies on tax incentives rather than direct government subsidies to individual tenants.

The Core Mechanism of the Section 42 Program

To understand Section 42 housing, one must understand the relationship between the Internal Revenue Service (IRS), state housing agencies, and private developers. The program does not grant money directly to renters. Instead, it provides tax credits to developers of multifamily rental projects.

When a developer builds or renovates a property under Section 42, they receive a dollar-for-dollar reduction in their federal tax liability for a period of ten years. In exchange for these credits, the developer must agree to keep a specific percentage of units affordable for a minimum of 30 years—often much longer depending on state requirements. Most developers sell these tax credits to private investors to raise equity for construction. This influx of capital reduces the amount of debt the developer needs to take on, which in turn allows them to offer units at restricted rent levels.

There are two primary types of credits: the 9% credit, which is competitive and usually used for new construction, and the 4% credit, which is typically used for projects financed with tax-exempt bonds or for the acquisition of existing buildings.

Critical Differences Between Section 42 and Section 8

A common point of confusion for many applicants is the distinction between Section 42 and the Section 8 Housing Choice Voucher program. While both fall under the umbrella of "affordable housing," they operate on completely different principles.

Subsidy Attachment

In the Section 8 program, the subsidy is often "tenant-based," meaning it is attached to the person. If a tenant moves, the voucher moves with them. In Section 42, the subsidy is "project-based" and attached to the physical unit. If a tenant moves out of a Section 42 apartment, they lose the benefit of the restricted rent.

Rent Calculation

In Section 8, the tenant typically pays exactly 30% of their adjusted gross income toward rent, and the government covers the remainder. In Section 42, the rent is not tied to the tenant's individual income. Instead, it is capped at a fixed rate based on the Area Median Income (AMI). This means a tenant in a Section 42 unit might pay more or less than 30% of their specific income, depending on where their earnings fall relative to the cap.

Administration

Section 8 is managed by local Public Housing Authorities (PHAs) and the Department of Housing and Urban Development (HUD). Section 42 is governed by the IRS and administered by state-level Housing Finance Agencies (HFAs). Consequently, you do not apply for Section 42 through a government office; you apply directly at the leasing office of the specific apartment complex.

Income Eligibility and Area Median Income (AMI)

The backbone of Section 42 eligibility is the Area Median Income (AMI). Each year, HUD calculates the AMI for every county and metropolitan area in the United States. Section 42 properties are required to reserve units for households earning a certain percentage of this figure.

The Minimum Set-Aside Tests

Developers must choose one of three federal "set-aside" tests to qualify for tax credits:

  1. The 20-50 Test: At least 20% of the units must be occupied by households with incomes at or below 50% of the AMI.
  2. The 40-60 Test: At least 40% of the units must be occupied by households with incomes at or below 60% of the AMI.
  3. The Average Income Test: At least 40% of the units must be occupied by households with an average income that does not exceed 60% of the AMI, allowing individual units to be restricted at 20%, 30%, 40%, 50%, 60%, 70%, or 80% of the AMI.

In practice, many properties operate under a "100% tax credit" model, where every single unit in the building is rent-restricted to households earning 60% AMI or less.

How Income Is Verified

Applying for a Section 42 unit involves a rigorous income certification process. Management must verify every source of income for every adult member of the household. This includes:

  • Wages, salaries, tips, and bonuses.
  • Net income from business operations.
  • Interest and dividends from assets.
  • Social Security, annuities, and insurance policies.
  • Unemployment and disability compensation.
  • Alimony and child support.

Property managers are required to use "Third-Party Verification," meaning they must contact employers, banks, and government agencies directly to confirm the numbers provided by the applicant. This process must be completed before a lease is signed and, in many cases, must be repeated annually to ensure the household remains compliant.

Understanding Rent Caps in Section 42 Units

One of the most important aspects of Section 42 for tenants to understand is how the maximum allowable rent is determined. These rents are calculated based on the assumption that a household should not spend more than 30% of their income on housing. However, the calculation uses the AMI limit, not the tenant’s actual income.

For example, if the 60% AMI limit for a one-bedroom apartment in a specific county is $1,200, the landlord cannot charge more than $1,200 for that unit, regardless of whether the tenant earns $20,000 or $40,000 a year.

Utility Allowances

The maximum rent also includes a "utility allowance." If the tenant is responsible for paying their own electricity or gas, the landlord must subtract a predetermined amount from the maximum allowable rent. If the maximum rent is $1,200 and the utility allowance is $100, the most the landlord can collect in cash rent is $1,100.

The Full-Time Student Rule

A unique and often frustrating aspect of Section 42 is the "Full-Time Student Rule." Generally, a household comprised entirely of full-time students is ineligible to live in a Section 42 unit. The IRS implemented this rule to prevent the program from being used as subsidized dormitory housing for college students who may have low current income but high future earning potential or parental support.

A student is defined as anyone who has been a full-time student for at least five months out of the current calendar year at an educational institution with regular facilities and staff.

Exceptions to the Student Rule

There are five specific exceptions that allow an all-student household to qualify:

  1. Single Parents: A single parent and their children, provided no one in the household is a dependent of another individual (except for the other parent).
  2. Married Couples: Students who are married and entitled to file a joint tax return.
  3. TANF Recipients: At least one household member receives assistance under Title IV of the Social Security Act (Temporary Assistance for Needy Families).
  4. Job Training Programs: At least one household member is enrolled in a job training program receiving assistance under the Job Training Partnership Act or similar federal, state, or local laws.
  5. Former Foster Care: At least one household member was previously in a foster care program.

The Application and Certification Process

Securing a Section 42 apartment is more complex than renting a market-rate unit. Because the landlord faces severe financial penalties (the loss of tax credits) if they lease to an unqualified household, the screening process is exhaustive.

Step 1: Initial Inquiry

You must contact the property directly. Ask specifically for their "compliance manager" or the person in charge of "tax credit applications." Inquire about their specific AMI limits and current availability.

Step 2: The Application

You will fill out a detailed application that asks for every bank account, retirement fund, life insurance policy, and employment history. Be prepared to provide the last 4-6 consecutive pay stubs, six months of bank statements, and tax returns.

Step 3: Asset Calculation

Under Section 42 rules, assets themselves aren't usually a bar to entry, but the income they generate is counted. If you have $50,000 in a savings account, the interest it earns is added to your annual income. If your total assets exceed $5,000, the manager must use the greater of the actual income from the assets or a "passbook rate" determined by HUD.

Step 4: The Tenant Income Certification (TIC)

Once all verifications are back, the manager prepares a TIC. This document is a legal summary of your household’s eligibility. Both the tenant and the manager sign this form, and it is kept in a compliance file that may be audited by the state housing agency.

Step 5: Annual Recertification

In most Section 42 properties, you must go through this entire process again every year. You will need to provide updated income and asset information to prove you are still under the limits, though some "100% tax credit" buildings have waived the annual income requirement under certain IRS regulations.

Common Obstacles and How to Navigate Them

Based on experience observing the LIHTC market, several common issues can derail a Section 42 application.

Fluctuating Income

If you are an hourly worker whose hours vary or if you receive seasonal bonuses, the property manager will typically average your last several months of income and project it forward for the next 12 months. This can sometimes push an applicant slightly over the limit, even if their actual year-to-date earnings are low.

The "Next Available Unit" Rule

If a tenant's income increases above the limit after they have moved in, they are not immediately evicted. However, under the "Next Available Unit Rule," if a tenant's income exceeds 140% of the current income limit, the landlord must rent the next available unit of comparable or smaller size in that building to a qualifying low-income household. The over-income tenant can usually stay but may eventually see their rent increase to market rates if the building has market-rate units available.

Credit and Criminal Background Checks

While Section 42 focuses on income, it is still a private housing program. Landlords can (and usually do) run credit and criminal background checks. Having a low income qualifies you for the rent, but you must still meet the landlord's tenancy standards.

How to Find Section 42 Housing Near You

Since there is no single national "Section 42" office, finding these apartments requires a localized search.

  1. State Housing Finance Agency (HFA) Lists: Every state has an HFA (e.g., CalHFA in California, NYS Homes and Community Renewal in New York). Their websites typically feature a "Find Affordable Housing" tool or a downloadable PDF of all properties that have ever received tax credits.
  2. HUD User Data: The HUD User website maintains a LIHTC Database where you can search by city, county, or zip code to see which buildings were funded via Section 42.
  3. Online Rental Portals: Websites like Apartments.com or Zillow often include "Income Restricted" or "Affordable Housing" filters.
  4. Local Non-Profits: Organizations like Habitat for Humanity or local community development corporations often manage Section 42 properties or maintain lists of available affordable units.

Advantages and Disadvantages of Section 42 Housing

Benefits

  • High Quality: Because tax credits are competitive, developers often build Section 42 properties to a very high standard to win the state's approval. These are often some of the newest and best-maintained apartments in the affordable market.
  • Rent Stability: Rent increases are strictly controlled by HUD's annual AMI adjustments. You won't face a sudden 20% rent hike because the neighborhood got popular.
  • Professional Management: LIHTC properties require specialized compliance knowledge, so they are almost always managed by professional companies rather than individual "mom-and-pop" landlords.

Drawbacks

  • Intrusive Verification: The annual requirement to disclose every bank statement and pay stub can feel like an invasion of privacy.
  • Strict Rules: The student rule and household composition rules are inflexible. Adding a roommate or a partner later can jeopardize the entire household's eligibility.
  • Long Waitlists: Due to the high quality and low rent, waitlists for Section 42 units can range from six months to several years.

Frequently Asked Questions (FAQ)

Can I live in Section 42 housing if I have a Section 8 voucher?

Yes. In fact, Section 42 landlords are generally prohibited from discriminating against Section 8 voucher holders. The voucher will pay its portion of the Section 42 restricted rent, making the unit even more affordable for the tenant.

What happens if my income goes up while I am living there?

In most cases, you will not be asked to move. As long as you were income-qualified when you first moved in, you are considered "grandfathered." However, if your income exceeds 140% of the limit, the "Next Available Unit" rule applies to the landlord.

Are pets allowed in Section 42 housing?

This is entirely up to the individual property owner. Section 42 is a tax program, not a set of building management rules. However, Service Animals and Emotional Support Animals (ESAs) must be accommodated under the Fair Housing Act, provided the tenant has the proper documentation.

Is there a minimum income requirement?

While the IRS sets a maximum income, many landlords set a minimum income to ensure you can afford the rent. A common rule of thumb is that the tenant must earn at least 2 to 2.5 times the monthly rent.

Summary

Section 42 housing serves as a vital bridge in the American housing market, providing high-quality, rent-restricted apartments to millions of households. By leveraging private investment through the Low-Income Housing Tax Credit, the program ensures that affordable options remain available even in expensive metropolitan areas. For potential renters, the key to success is understanding the AMI limits of their specific region, being prepared for an intensive income verification process, and applying directly to properties long before they need to move. While the "Full-Time Student Rule" and annual recertifications add a layer of complexity, the trade-off is often a modern, safe, and stable place to call home at a price that reflects the reality of the local economy.
