ADU Pass
Virgin Islands
The U.S. Virgin Islands faces housing challenges from hurricane recovery and limited developable land. Accessory dwelling units give property owners a practical way to expand housing capacity on existing lots. ADU Pass helps Virgin Islands residents navigate the permit process for secondary structures.

State ADU details
State financing programs
USVI's primary housing finance vehicle is the Virgin Islands Housing Finance Authority (VIHFA), the territorial housing finance authority operating since June 1984. VIHFA is the lead agency administering CDBG-DR and CDBG-MIT funding ($1.86B+ allocated by HUD after the 2017 Hurricane Irma/María disasters); the broader recovery funding totals several billion dollars across multiple HUD allocations. The VIHFA-administered programs that touch ADU-equivalent work include the Homeowner Reconstruction Program for storm-damaged homes (where reconstruction can include accessory or replacement structures within program limits) and various utility-restoration programs (electrical, plumbing). VIHFA is NOT publishing a dedicated consumer ADU loan; ADU-equivalent work flows through the disaster-recovery channel or through conventional bank financing (Banco Popular VI, FirstBank VI). VIHFA also operates first-mortgage and homebuyer-assistance programs.
State insurance regimes
USVI's insurance regulator is the Division of Banking, Insurance and Financial Regulation, sitting under the Office of the Lieutenant Governor. The Division regulates insurance companies, insurance producers, captive insurance companies, and third-party administrators. The USVI has NO FAIR Plan, NO state-of-last-resort property insurer, and NO wind pool. Hurricane exposure is the dominant property-insurance issue: Hurricanes Irma and María (back-to-back Category 5 storms in September 2017) caused catastrophic damage; reinsurers subsequently declined or sharply limited the amount and type of risk they will undertake in USVI, producing a structural insurance-availability problem. Many USVI homeowners struggle to secure conventional homeowners coverage; admitted-market premiums have risen sharply and surplus-lines capacity is limited. The Division publishes Updated Claims Handling Guidelines for Residential Hurricane Claims and runs annual hurricane-preparedness consumer outreach. FEMA NFIP provides flood coverage; ADUs follow the parcel's flood-zone determination.
Known state issues (3)
- policy-review (since 2017-09-20) — ADU project pro-formas in USVI must include a substantial insurance-cost premium and account for the risk that admitted-market coverage may not be available. Construction must meet category-5 wind-uplift detailing and impact-rated openings as a de facto insurability prerequisite. This is one of the highest-cost insurance regimes for ADU-bearing residential property in any US jurisdiction.
- other (since 2014-07-29) — ADU practitioners working in USVI should expect a heavier permit pathway than mainland equivalents. The DPNR Group Dwelling application or PAD designation are the practical routes; both require more documentation and review than a by-right permit. Site-by-site feasibility analysis is essential.
- policy-review (since 2020-01-01) — ADU-adjacent reconstruction work that depends on CDBG-DR reimbursement faces administrative risk. Program-rule changes between application and reimbursement can affect funded scope. Bank financing and insurance backstops should not be relied upon as substitutes for CDBG-DR reimbursement.
Federal (United States) — ADU-relevant rules and programs
Federal ADU law
The United States has no federal statute that directly regulates accessory dwelling unit entitlement or design. Land-use authority over ADUs resides with states and local governments under the traditional police power. Federal engagement is limited to financing (Fannie/Freddie/FHA/VA/USDA), flood insurance (FEMA/NFIP), and discretionary housing programs (HUD), which are recorded in sibling sections of this file.
Federal financing programs
Federal housing-finance agencies and GSEs set nationwide underwriting rules that govern whether an ADU can be financed, appraised, and counted toward mortgage qualifying income. The relevant actors are Fannie Mae, Freddie Mac, FHA (HUD), VA, and USDA Rural Development.
Federal tax credits
There is no ADU-specific federal tax credit. ADUs may incidentally qualify for existing federal energy-efficiency and clean-energy tax credits when the ADU construction includes qualifying measures.
Federal housing programs
HUD administers several discretionary programs that can fund ADU-related activity at the grantee's election, but none is an ADU-specific program.
