    RAD vs. Section 18: The Comparison Guide

    A plain-English, side-by-side technical comparison for Public Housing Authorities evaluating Rental Assistance Demonstration (RAD) conversions against Section 18 Demolition/Disposition. Built for boards, executive directors, and development teams in the research phase.

    How this page differs: this is a decision-framework resource, not a service page. For RAD execution specifically, see RAD Consulting Services.

    RAD Consultants

    Rental Assistance Demonstration (RAD)

    RAD converts public housing operating and capital subsidy into a long-term Section 8 contract — typically Project-Based Voucher (PBV) or Project-Based Rental Assistance (PBRA). Properties exit the public housing program permanently and gain access to private debt and LIHTC equity while preserving affordability for current residents.

    Best for stable, occupied portfolios with moderate rehabilitation needs where preserving long-term affordability is the primary goal.

    Section 18 Consultants

    Section 18 Demolition / Disposition

    Section 18 of the U.S. Housing Act of 1937 allows a PHA to remove obsolete or distressed units from public housing inventory. Displaced residents receive Tenant Protection Vouchers (TPVs), and replacement housing can be redeveloped using LIHTC, mixed-finance, or partner-developer structures.

    Best for properties failing the obsolescence or cost test — where FMR-level voucher rents unlock the debt capacity needed for full redevelopment.

    Decision Framework

    Which path fits your portfolio?

    Each program serves a distinct strategic purpose. The right choice depends on property condition, resident profile, and your long-term capital plan.

    Preservation Path

    RAD Conversion

    Strengths

    • Permanent affordability via long-term HAP contract
    • Streamlined application via HUD Resource Desk
    • Strong fit for occupied portfolios with moderate rehab
    • Predictable PBV/PBRA subsidy structure

    Trade-offs

    • Initial contract rents capped at current funding
    • Lower debt capacity vs. Section 18
    • Right to Return adds relocation complexity

    Redevelopment Path

    Section 18 Demo/Dispo

    Strengths

    • FMR-based rents unlock significantly higher debt
    • Stronger developer cash flow and fee potential
    • Best path for obsolete or distressed properties
    • Flexible reuse of land — including mixed-income

    Trade-offs

    • Longer approval timeline (9–18 months for letter)
    • Obsolescence/cost test required
    • Resident relocation under URA — higher friction
