When Affordable Stops Being Affordable: The Hidden Instability in AMI-Based Housing

By HRCNN Hampton Road Construction News Network Staff Writer

Across Virginia and much of the country, “affordable housing” is most often defined by its relationship to a region’s Area Median Income (AMI)—a figure calculated annually by the U.S. Department of Housing and Urban Development (HUD) to represent the midpoint of income distribution within a given region. Multifamily developments that receive public incentives or comply with local inclusionary zoning ordinances often reserve a certain percentage of units for households earning 30%, 50%, 60%, or 80% of the AMI. In theory, this system ensures that low- and moderate-income families have access to safe, decent housing. But in practice, AMI-based affordability has a time limit—and many renters are discovering just how short that window can be.

Rent levels in these units are typically pegged to HUD’s annual income limits, which are adjusted every year based on inflation, regional wage shifts, and other economic indicators. However, while initial lease-up rents may be within reach for families earning at or below the targeted AMI bracket, the allowable annual rent increases—often tied to fixed percentages or indexed escalators—can outpace actual income growth for tenants. Over time, the same unit that once qualified as “affordable” under the program’s metrics may become a financial strain, especially for tenants whose wages have stagnated or who have experienced job or family disruptions.

This is particularly problematic in high-demand housing markets like Northern Virginia, Hampton Roads, and the Richmond metropolitan area, where base AMI levels have been climbing steadily year over year. As AMIs rise, so too do the rent ceilings for so-called affordable units. Yet, not all households see a corresponding increase in earnings. Many renters—especially seniors, single parents, or essential workers—find themselves priced out of the very units that were designed to serve them. This leads to a painful irony: a unit remains technically “affordable” on paper, even as the tenant can no longer afford to stay.

This cycle—entering an affordable unit only to be forced out a few years later—creates what housing advocates call “renter instability.” Families must uproot children from schools, face transportation disruptions, and re-enter increasingly competitive rental markets with fewer viable options. The emotional and financial toll is considerable, particularly for households who moved into these units expecting long-term stability and relief from volatile market-rate housing costs. Instead, they are thrust back into the uncertainty that affordable housing policy was designed to mitigate.

One structural contributor to this problem is the lack of long-term rent stabilization or income recertification requirements in many inclusionary housing agreements. While some localities and Low-Income Housing Tax Credit (LIHTC) projects do require periodic income recertification to ensure tenants still qualify, others do not—allowing landlords to gradually escalate rents while existing tenants bear the burden. This is compounded in jurisdictions where inclusionary zoning is voluntary or poorly enforced, leading to inconsistent outcomes across neighborhoods.

To address this issue, several housing experts and municipal planners are advocating for stronger affordability protections: longer affordability periods (30–50 years), graduated rent caps, and enhanced tenant protections against excessive rent escalations. Others are exploring policy mechanisms such as “rent-to-income” lock-ins, which ensure rent increases remain in sync with a household’s actual earnings rather than the broader AMI curve. These reforms could help preserve the intent of affordable housing programs and promote real housing security for tenants over time.

As Virginia continues to explore inclusionary zoning strategies and expand its multifamily housing stock, it is imperative to recognize that affordability is not static. What a family can afford today may not hold true in five years, especially without policy safeguards in place. To truly serve low- and moderate-income residents, our housing policies must evolve from simply providing affordable units to preserving affordability for the people who need it most—over time, not just at the lease signing.

Balancing Safety and Infill: Virginia Reexamines Single-Stair Design Standards

In a pivotal meeting that could influence how future housing is built across the Commonwealth, Virginia’s Department of Housing and Community Development (DHCD) convened a diverse advisory group this week to evaluate a controversial building code proposal: whether to allow four-story multifamily buildings to be constructed with a single interior exit stairway.

The discussion centered on Proposal B1006.3.4-24, which seeks to extend the current allowance for single-exit stair buildings—currently capped at three stories—to include a fourth story, provided that enhanced safety measures are integrated. Supporters argue that the change would unlock dense urban infill development on constrained lots, improve building efficiency, and align Virginia with emerging national model codes. Opponents, however, caution that removing a second stairwell could introduce unacceptable life safety risks, especially in rural areas.

“The goal isn’t to remove stairs for cost savings,” one advisory group member said. “It’s about allowing more flexible, climate-adaptable designs on small sites, with bedrooms on exterior walls and more access to natural light.”

The proposal mirrors recent language approved by the National Fire Protection Association (NFPA) and submitted for consideration in the 2027 International Building Code (IBC) update. However, Virginia is not bound by either framework and must decide whether to adopt an independent provision. The June 24 meeting marked the first formal effort to gather input from fire officials, architects, engineers, local government staff, planners, and other industry stakeholders.

Design and Energy Considerations

Much of the early discussion focused on the design benefits of single-stair buildings. Advocates noted that the reduction of internal corridors allows for more efficient layouts and better cross-ventilation. Architects in the room pointed out that long, deep units with limited window exposure are more energy-intensive and less desirable for residents. They also cited increased flexibility in mechanical system design and solar orientation.

However, some code officials raised concerns about energy-code compliance, especially related to window-to-wall ratios and thermal performance. While most participants agreed that energy issues could be addressed through design choices, others emphasized the need for clear language to prevent misinterpretation during enforcement.

Fire and Life Safety Remain the Primary Concern

As the conversation shifted, fire service professionals voiced strong reservations. Several attendees noted that in jurisdictions with limited fire coverage—particularly in rural parts of Southwest Virginia—response times can exceed 15 minutes, making the presence of a second exit stair critical to resident survival during emergencies.

“New York and Seattle may show low fatality rates in single-exit buildings, but they have response times under four minutes and deep suppression capacity,” one member said. “We can’t design Virginia code around those standards.”

The concern was not only about egress time, but also about operational conflict—residents attempting to evacuate through the same stairwell that fire personnel need to access for response. The discussion included standpipe requirements, positive pressure ventilation, and notification systems. Several participants emphasized the importance of clear mandates for manual fire alarms and early alert systems, especially in buildings that may lack a second means of egress.

Proposed Revisions Emerge

Despite the disagreement, the group found some common ground. By the end of the meeting, there was general consensus on limiting the proposal strictly to interior stairwells, excluding exterior stairs for now due to additional vulnerabilities. The group also discussed amendments requiring stairwell doors to open in the direction of travel, prohibiting direct access from dwelling units into exit stairs, and revising language to align occupancy calculations with gross floor area rather than net area to avoid enforcement conflicts.

Emergency escape and rescue openings (EEROs), which are required in three-story buildings under the current code, were flagged for inclusion in any revised four-story provision. Participants also urged consistency with existing IBC and Virginia Construction Code requirements, including clarifications on notification system connectivity and sprinkler integration.

What’s Next

DHCD staff indicated that they would work with the code change proponent and fire service representatives to draft a revised proposal. A second review and consensus process will be conducted via email, with a virtual meeting to follow if necessary. The revised language is expected to be narrower in scope, more technically precise, and focused on conditions that reflect Virginia’s unique fire service landscape.

As Virginia continues to wrestle with affordability, density, and safety in housing policy, the single-stair proposal offers a case study in balancing innovation with public protection. Whether the compromise will satisfy both sides remains to be seen.

HRCNN will continue to report on code reform efforts and land use policy shaping Virginia’s built environment.
