Every fiscal year, the Department of Housing and Urban Development publishes updated utility allowance factors that directly affect how much rent can be charged in HUD-assisted properties and how utility costs are allocated between tenants and property owners. For FY 2026, HUD released its updated factors with an effective date of February 11, 2026, following the publication of Annual Adjustment Factors in December 2025. These changes have immediate implications for property managers, Public Housing Authorities, and owners of multifamily housing receiving project-based rental assistance.
The FY 2026 factors reflect significant shifts in energy costs that accumulated throughout 2024 and 2025. Natural gas prices in the Northeast saw sustained increases, electricity rates in the Southeast and Southwest climbed due to grid infrastructure investments, and water and sewer costs continued their decade-long upward trajectory in virtually every metropolitan area. Understanding what changed, why it changed, and what property managers need to do in response is essential for maintaining compliance and ensuring that tenants are not overburdened by utility costs that exceed their allowances.
Overview of the FY 2026 Annual Adjustment Factors
HUD's Annual Adjustment Factors are used to adjust contract rents for units under the Section 8 project-based program and to recalibrate utility allowances for housing choice voucher programs. The FY 2026 AAFs were published in the Federal Register in December 2025, with implementation required by February 11, 2026. The factors are expressed as percentage changes relative to the prior year and are calculated at the metropolitan statistical area level to reflect local market conditions.
Key Changes in Energy Cost Factors
The most significant changes in the FY 2026 factors relate to energy costs. Electricity factors increased in 38 of the 50 largest metropolitan areas, with the highest increases concentrated in the PJM Interconnection territory covering the Mid-Atlantic states and in the ERCOT territory covering Texas. Natural gas factors rose in 42 of the 50 largest metros, reflecting a combination of pipeline infrastructure costs, increased export demand, and state-level clean energy surcharges. The national weighted average increase for electricity was 6.8 percent, while natural gas factors increased by an average of 9.2 percent.
These increases are not uniform. Some markets saw electricity factor increases exceeding 12 percent, while a handful of markets with significant renewable energy capacity saw modest decreases. Property managers operating across multiple states need to review the factors for each specific MSA rather than applying a national average. The MSA-level detail is published in the HUD Federal Register notice and is available through HUD's online utility model.
Water and Sewer Factor Adjustments
Water and sewer cost factors continued to increase faster than energy factors in many markets. The national average increase was 7.4 percent for water and 8.1 percent for sewer. Several major cities, including Atlanta, Houston, and Philadelphia, saw combined water and sewer factor increases exceeding 10 percent, driven by aging infrastructure replacement programs and EPA consent decree compliance costs. For properties where tenants are responsible for water and sewer payments, these increases have a direct impact on the utility allowance and, by extension, on the maximum contract rent.
Implementation Timeline and Requirements
HUD requires that updated utility allowances reflecting the FY 2026 factors be implemented no later than 90 days after the effective date of the AAF publication. For the February 11 effective date, this means property managers and PHAs must have updated allowance schedules in place by May 12, 2026. However, HUD strongly encourages earlier implementation to minimize the period during which tenants may be paying utility costs that exceed their allowances.
Steps for Property Managers
- Download the updated factors. Obtain the FY 2026 AAF tables from HUD's website or the Federal Register. Identify the factors applicable to each MSA where you operate HUD-assisted properties.
- Recalculate utility allowances. Apply the updated factors to your existing consumption baselines. If you use the HUD utility model, input the new rate data. If you calculate allowances independently, multiply your current per-unit consumption estimates by the updated rates.
- Compare old and new allowances. Identify units where the allowance change exceeds 10 percent, as these may require accelerated implementation or interim adjustments to tenant rent calculations.
- Notify affected tenants. Provide written notice of the updated utility allowance at least 30 days before implementation. The notice should include the old allowance, the new allowance, and the effective date.
- Update rent calculations. Recalculate the Housing Assistance Payment for each affected unit using the new utility allowance. Submit updated rent calculations to the PHA or contract administrator as required.
"Property managers who delay implementing updated utility allowance factors beyond the 90-day window risk compliance findings during REAC inspections and Management and Occupancy Reviews. More importantly, they risk overburdening tenants with utility costs that exceed program intent."
Regional Highlights: Where the Biggest Changes Occurred
While every MSA has its own specific factors, several regional patterns are worth highlighting for property managers who operate portfolios across multiple markets.
Northeast and Mid-Atlantic
The Northeast continues to have the highest absolute utility costs and some of the largest year-over-year increases. Boston, New York, and Hartford all saw electricity factor increases above 8 percent, driven by winter reliability costs and transmission infrastructure investments. Natural gas factors in the region increased by 10 to 14 percent, reflecting pipeline capacity constraints and increasing demand from gas-fired power generation. For affordable housing operators in these markets, the combined impact on utility allowances is substantial, with some two-bedroom unit allowances increasing by $30 to $50 per month.
Southeast and Texas
Texas and Florida saw some of the largest electricity factor increases nationally. The ERCOT market's ongoing challenges with peak demand pricing, combined with transmission and distribution upgrades required after extreme weather events, pushed electricity factors up by 9 to 12 percent in Houston, Dallas, and San Antonio. Florida markets experienced similar increases as Florida Power and Light and Duke Energy implemented approved rate base adjustments for hurricane hardening and grid modernization. Summer cooling costs in these markets are a significant component of the utility allowance, and the FY 2026 factors reflect the reality that cooling is becoming more expensive, not less.
West Coast
California markets present a mixed picture. Electricity factors increased modestly in most MSAs, tempered by the state's aggressive renewable energy buildout and the resulting decline in wholesale energy costs during peak solar hours. However, the state's time-of-use rate structures mean that evening and morning consumption, when solar generation drops, is priced significantly higher. Natural gas factors in California increased by 7 to 9 percent, reflecting both commodity cost increases and the state's gas infrastructure decommissioning surcharges. Pacific Northwest markets saw relatively smaller increases, benefiting from hydroelectric generation that keeps wholesale costs lower than the national average.
Impact on Property Financial Performance
For owners of HUD-assisted properties, utility allowance changes have a direct impact on revenue and cash flow. When the utility allowance increases, the maximum contract rent decreases by the same amount, assuming the gross rent cap remains constant. This means that a $40 per month increase in the utility allowance translates to a $40 per month decrease in potential rent revenue per unit, or $480 per unit per year. For a 200-unit property, that is $96,000 in annual revenue that shifts from the owner to the utility cost column.
Property owners can mitigate this impact through energy efficiency investments that reduce actual utility consumption. If a building envelope upgrade or HVAC modernization reduces per-unit energy consumption by 20 percent, the utility allowance calculation will eventually reflect that lower consumption, allowing the contract rent to recover. The economics of energy efficiency investments in affordable housing are therefore not just about operating cost savings. They are about preserving rental revenue capacity within the HUD rent structure.
Preparing for Future Factor Updates
The FY 2026 factors are a point-in-time snapshot, and energy markets continue to evolve rapidly. Property managers who want to stay ahead of future updates should establish a monitoring process that tracks utility rate filings in their operating markets, subscribe to Federal Register notifications for HUD AAF publications, maintain a centralized database of current utility allowances by property and unit type, and build energy efficiency improvements into their capital planning cycle to offset rising utility costs.
Utility data platforms that aggregate rate information and consumption data across multiple properties and jurisdictions can significantly reduce the administrative burden of annual allowance updates. Instead of manually collecting rate schedules from dozens of utility providers, these platforms maintain current rate data and can flag when rate changes trigger recalculation thresholds. The result is faster implementation of updated allowances, better documentation for compliance audits, and more accurate financial projections for the property's operating budget.
