The new rule does not eliminate TPVs. It limits how many vacant units can be counted when HUD decides how many replacement vouchers to fund.
What Changed In 2026
HUD explains that its 2025 policy, and the policy for many prior years, provided replacement TPVs for vacant units that had been occupied by an assisted family within the previous 24 months. That gave PHAs and owners a longer runway. A unit could sit vacant during planning, relocation, closing delays, capital needs review, or redevelopment preparation and still remain within the TPV count if it had been occupied in the prior two years.
For 2026 funding, HUD shortened that vacant-unit lookback to 12 months. Replacement TPVs will be provided for occupied units and for vacant units only if the vacant unit was occupied by an assisted family within the previous 12 months and is no longer available as assisted housing. Anything outside that window may fall out of the TPV allocation, even if the unit was historically part of the assisted property.
Why HUD Tightened The Rule
HUD says the change is driven by the need to constrain future costs and the possibility of large replacement TPV requests in 2026. That is budget language, but the impact is local. If a PHA expected vouchers for every vacant unit in a repositioning transaction, the new rule may reduce the number of funded vouchers. Fewer vouchers can mean less rental assistance, lower projected revenue, and weaker financing assumptions.
The agency also warns that, depending on demand and funding availability, it may later suspend the allocation of replacement TPVs for vacant units or reduce the initial increment term and associated funding to less than 12 months. That warning matters because even the 12-month policy may not be the final floor if demand overwhelms available TPV funding.
The Public Housing Timing Test
For public housing actions, the 12-month clock is measured from the time of the Special Applications Center approval or the Choice Neighborhoods Initiative award date. If a vacant public housing unit was last occupied by an assisted family within 12 months of that approval or award, it may be included in the replacement TPV count.
That creates a planning problem. A PHA that holds units vacant while waiting for demolition/disposition approval can accidentally age units out of eligibility. The longer the pre-approval period drags, the more vacant units may cross the 12-month line. A vacancy that looked manageable in the repositioning schedule can become a lost voucher in the funding calculation.
The Multifamily Timing Test
For multifamily housing actions, the 12-month clock is measured from the eligibility event. That event may be tied to a prepayment, opt-out, termination, or other action that triggers TPV eligibility. The vacant unit must have been occupied by an assisted family within the previous 12 months from that event.
This means owners of HUD-assisted multifamily properties cannot treat vacancy history as an afterthought. If the transaction depends on TPVs, the owner and PHA must know exactly when each unit was last occupied, which families were assisted, and when the eligibility event will occur. A sloppy rent roll can become a funding loss.
Why The 24-Month Grandfathering Matters
HUD did not apply the 12-month rule to every transaction retroactively. SAC approvals, CNI awards, or TPV eligibility events dated on or after October 1, 2018, and before the effective date of the notice remain subject to the older 24-month policy. HUD also provides a special transition for certain RAD conversions.
If a RAD conversion will result in TPVs and the RAD Financing Plan for a RAD/Section 18 blend, or the RAD Conversion Plan for a Moderate Rehabilitation or Single Room Occupancy conversion, was submitted before the effective date of the notice, the 24-month policy still applies. That transition protection can be extremely valuable for deals already deep in the pipeline.
The key question for every transaction is now brutally specific: which date controls, and how many vacant units were occupied within the correct lookback window?
Replacement TPVs Are Not The Same As Relocation TPVs
HUD’s notice also points to an important distinction. TPV allocations can be replacement vouchers or relocation vouchers. Relocation vouchers are tied to families impacted by the conversion action and are not for vacant units. Replacement TPVs, by contrast, can help replace assisted units that are being lost or converted, including certain qualifying vacant units.
That distinction matters because vacant-unit policy is about replacement TPVs. If a family is actually impacted and eligible for relocation assistance, the analysis is different. But if the unit is empty and the PHA hoped to count it to support future subsidy, the 12-month vacancy rule becomes central.
The Financing Risk For RAD/Section 18 Blends
RAD/Section 18 blends often rely on a careful mix of RAD-assisted units, Section 18 disposition authority, and tenant protection vouchers. The projected voucher count can affect rent levels, debt capacity, tax credit sizing, operating budgets, reserve requirements, and developer decisions. A reduction in eligible vacant units can ripple through the entire financing stack.
A project that expected TPV funding for 100 units may discover that only 85 units qualify because 15 vacant units crossed the 12-month line. That difference can lower revenue and force the transaction to resize debt, find more gap financing, reduce scope, phase work differently, or change the preservation plan. The vacancy rule is not just an occupancy rule. It is a capital planning rule.
Why PHAs Must Manage Vacancies Differently
Under a 24-month lookback, a PHA had more room to let distressed units sit vacant while planning a repositioning strategy. Under a 12-month lookback, vacancy becomes a ticking clock. Every vacant unit now needs a status date, last-assisted-occupancy date, rehab status, approval timeline, and TPV eligibility risk flag.
PHAs should not wait until the TPV application is being assembled to discover that half the vacancy history is unclear. They should build a unit-level tracker as soon as repositioning is being considered. The tracker should show the last assisted occupancy date, vacancy reason, whether the unit is offline, whether it can be reoccupied, and which approval or eligibility date will control the lookback.
Residents Can Be Affected Indirectly
The rule is about vacant units, so it may sound like residents are not affected. That is misleading. If fewer replacement TPVs are allocated, a redevelopment plan may have less subsidy to support replacement housing. A PHA may have fewer resources to preserve deeply affordable units. A project may be downsized, delayed, or redesigned.
Current residents still must be offered required TPV assistance when they are eligible and impacted. But the long-term affordability plan for the property can change if vacant units no longer generate replacement vouchers. A vacancy rule can become a resident protection issue when it reduces the future supply of assisted homes.
The Documentation Burden Is Higher
The new rule makes documentation more important. PHAs and owners should preserve rent rolls, occupancy records, tenant assistance status, move-out dates, unit status reports, PIC or successor system data, inspection records, vacancy logs, and correspondence showing why units were vacant. HUD will not want vague claims that a unit was “recently occupied.” It will need evidence.
This is especially important for properties with long predevelopment periods. If a project has been discussed for years, staff turnover may have weakened the file. Old occupancy records may be incomplete. Unit numbers may have changed. Data systems may not match property records. Before submitting a TPV request, the file should be reconciled unit by unit.
The PUC Funding Issue
HUD calculates TPV funding based on the average per unit cost in the administering PHA’s HCV program. If the PHA believes that average PUC will be insufficient, it can request an upfront increase or a later adjustment during the initial funding increment. The request must be supported by evidence of rent amounts, rent reasonableness, and a budget authority gap analysis.
This matters because a PHA can face two problems at once: fewer qualifying vacant units and insufficient per-unit funding for the vouchers it does receive. HUD will not accept 2026 TPV PUC increase requests after December 31, 2026, and all additional TPV funding is subject to available appropriations. Waiting too long can lock in a weak funding level.
What Owners And Developers Should Do Now
Owners and developers should stress-test every transaction that assumes TPVs. Identify the controlling event date. Count occupied units separately from vacant units. For each vacant unit, determine whether an assisted family occupied it within the correct 12-month or grandfathered 24-month window. Then rerun the financing model with the lower voucher count.
They should also coordinate early with the PHA. The PHA is the entity that will administer the vouchers and interact with HUD. A developer cannot fix a TPV eligibility problem at closing if the occupancy history was never documented. The earlier the team identifies aging vacancies, the more options it may have.
What PHAs Should Avoid
PHAs should avoid warehousing vacancies without a clear TPV strategy. They should avoid assuming that all historical assisted units will generate replacement vouchers. They should avoid using outdated 24-month assumptions for new 2026 actions unless the transaction qualifies for grandfathering. They should avoid submitting TPV requests without a clean unit-by-unit eligibility file.
Most importantly, PHAs should avoid letting timing drift. A SAC approval date, CNI award date, eligibility event, RAD Financing Plan submission, or RAD Conversion Plan submission can decide which policy applies. In the new environment, dates are not administrative details. They are funding triggers.
Bottom Line
HUD’s 2026 TPV vacancy policy creates a stricter allocation environment. Occupied eligible units remain the core of tenant protection. But vacant units now generally count only if they were occupied by an assisted family within the previous 12 months, replacing the broader 24-month policy used in 2025 and many prior years. Some earlier approvals and certain submitted RAD plans remain under the 24-month rule, but new actions face the shorter clock.
For PHAs, owners, residents, and developers, the message is urgent: vacancy time now has a subsidy cost. A unit that sits empty too long can lose its ability to support a replacement TPV. That can shrink voucher allocations, weaken financing, reduce preservation capacity, and complicate redevelopment plans. The safest response is a disciplined vacancy tracker, early HUD coordination, clean occupancy records, conservative financing assumptions, and a simple rule for every repositioning team: do not let vacant units expire before the TPV decision is made.
