Rental Assistance Demonstration.

What RAD does

The Rental Assistance Demonstration (RAD) is a HUD program authorized by Section 219 of the Consolidated and Further Continuing Appropriations Act of 2012, and implemented primarily through HUD PIH Notice 2012-32 (revised multiple times, most recently REV-4 in 2019, with subsequent amendments). RAD converts legacy HUD subsidy programs — primarily traditional Public Housing — into long-term Section 8 contracts (either Project-Based Voucher or Project-Based Rental Assistance).

The strategic purpose: legacy public housing operates on annual appropriations and aging capital reserves that cannot support recapitalization. By converting to Section 8, properties gain access to the private capital markets — including LIHTC equity, tax-exempt bonds, conventional debt, and FHA insurance — for the substantial rehab those properties typically need.

Administered jointly by HUD's Office of Public and Indian Housing (PIH) and HUD's Office of Multifamily Housing, RAD is the largest public housing preservation initiative in HUD's history.

The two RAD components

RAD operates in two distinct components, both authorized under Section 219:

RAD First Component (RAD I)

Converts traditional Public Housing (Section 9 of the Housing Act of 1937) and Section 8 Moderate Rehabilitation properties to long-term Section 8 contracts. Originally capped at 60,000 units in 2012, the cap has been repeatedly raised by Congress and was effectively removed for public housing in the FY2018 omnibus. This component represents the bulk of RAD conversions.

RAD Second Component (RAD II)

Converts Section 8 Moderate Rehabilitation, Rent Supplement (Rent Supp), and Rental Assistance Payment (RAP) properties — all legacy programs no longer being renewed — to either tenant-protection vouchers or project-based contracts. RAD II ensures continuity of subsidy for tenants when these legacy contracts expire.

How conversion works

The conversion is technical but follows a consistent pattern:

1. Application. The Public Housing Authority (PHA) or owner submits a RAD application to HUD describing the project, the proposed conversion type (PBV or PBRA), the rehab scope, and the financing structure.
2. CHAP issuance. HUD issues a Commitment to Enter into a Housing Assistance Payments Contract (CHAP), establishing the contract rents and terms.
3. Financing closing. The owner secures construction debt, LIHTC equity, and any other capital. Most RAD conversions use 4% LIHTC + tax-exempt bonds + FHA insurance as the standard capital stack.
4. Construction/rehab. Capital improvements occur, often with tenants in place (the "in-place rehab") subject to RAD's tenant protection provisions.
5. HAP contract execution. Upon completion, HUD signs a long-term HAP contract (typically 20 years for PBV, with renewals; or 15-20 years for PBRA, renewable). The legacy public housing subsidy is terminated; Section 8 takes over.
6. Compliance. Property operates under Section 8 rules going forward, with annual contract administration and tenant recertification.

Contract rents

RAD rents are set at the lower of (a) current "Public Housing operating cost plus capital fund subsidy" or (b) Section 8 reasonable rents. HUD will not increase the federal subsidy through conversion — RAD is intended to be budget-neutral on a per-unit basis. The economic gain comes from accessing capital, not from increased operating subsidy.

Tenant protections

RAD includes among the strongest tenant protections in federal housing programs:

• Right to return. All current tenants have a right to return to the property after rehab, regardless of changes in eligibility rules.
• No re-screening. Existing tenants are not re-screened for income, criminal background, or other eligibility criteria.
• Continued occupancy. No tenant may be involuntarily displaced by RAD conversion (subject to relocation during construction).
• Choice Mobility option. After one year of post-conversion occupancy, tenants in PBV-converted units have the right to request a tenant-based voucher and move (subject to voucher availability). This option is not available in PBRA conversions.
• Family Self-Sufficiency. RAD properties may participate in FSS programs offering case management and asset-building.

RAD + LIHTC: the standard recapitalization structure

The combination of RAD conversion and 4% LIHTC + tax-exempt bonds is the standard structure for public housing recapitalization. Typical economics:

• Capital sources: Construction debt (bridged by tax-exempt bonds); 4% LIHTC equity (typically $0.88-$0.95 per credit dollar); seller financing from PHA (note evidencing prior public housing investment); HUD reserve transfers; sometimes FHLB AHP gap fill
• Operating sources: Section 8 HAP payments (contract rents); resident-paid rent contribution (typically 30% of income for very low income households); reserve replenishment
• Ownership: Typically a new LP, with the PHA or a PHA affiliate as GP. Some structures preserve the PHA's interest through master lease or other governance
• Compliance: Both LIHTC (15-year initial + extended use) AND Section 8 (20-year HAP) restrictions; whichever is more stringent governs the property

OBBBA's reduction of the PAB financed-by test to 25% (from 50%) has significantly increased the supply of bond cap available for RAD + 4% LIHTC deals starting January 1, 2026 — likely accelerating already-strong RAD conversion volume.

RAD-Section 18 hybrid conversions

Section 18 of the Housing Act of 1937 authorizes the demolition or disposition of public housing units that meet specific criteria (obsolete, economically nonviable, etc.). Section 18 provides Tenant Protection Vouchers (TPVs) for displaced residents, which can be project-based at a new or rehabilitated property.

HUD has developed RAD-Section 18 hybrid procedures allowing portfolios to combine the two paths — typically using RAD for the bulk of units and Section 18 for units that don't fit RAD's economic envelope. This hybrid is increasingly common for large redevelopment deals where the property's value exceeds RAD's rent-limit constraints.

How to apply

1. PHA initiative: RAD conversions are initiated by the PHA. Most large PHAs have RAD strategies covering their entire portfolio.
2. Pre-application: Internal feasibility — physical needs assessment (PNA), market study, preliminary financing plan
3. RAD application: Submit to HUD via the RAD Resource Desk. Application is detailed; pre-application technical assistance recommended.
4. CHAP issuance: 60-120 days typical from complete application to CHAP. Establishes contract rents and conversion terms.
5. Financing close: Working from CHAP, owner secures all capital sources. Most use the FHA 221(d)(4) New Construction or Substantial Rehab Mortgage Insurance Program or FHA 223(f) Acquisition/Refinance.
6. Closing and conversion: Simultaneous closing of capital and execution of HAP contract.

Pairing with other programs

• 4% LIHTC + tax-exempt bonds: Standard recapitalization combination
• FHA 221(d)(4) / 223(f) mortgage insurance: Most common debt structure
• HOME / HTF: Gap fill for deeper affordability components
• FHLB AHP: Additional gap subsidy for capital improvements
• Capital Magnet Fund: Particularly for CDFI-sponsored RAD deals
• State HFA soft loans: Many states have dedicated public housing preservation programs

Recent program developments

Tenant protection enhancements (2022-2025)

HUD has issued multiple PIH notices strengthening RAD's tenant protection provisions, particularly around relocation, right to return, and Choice Mobility implementation.

FAST Act and "Faircloth-to-RAD"

HUD has implemented procedures allowing PHAs to use unused "Faircloth Limit" public housing units (units PHAs are entitled to operate but never built) as the basis for new RAD-eligible Section 8 contracts. This expands RAD beyond strict 1-for-1 replacement of existing public housing.

OBBBA impact

OBBBA did not directly amend RAD. However, the OBBBA reduction of the bond financed-by test from 50% to 25% (effective January 1, 2026) substantially increases capacity for RAD + 4% LIHTC + bonds deals, which is the dominant structural pattern in RAD conversions.
