HOA prevalence & preemption

State HOA preemptionno

Puerto Rico's condominium regime is more sophisticated than most US territories — Law 129-2020 modernized the framework, mandated separate operating and reserve accounts, and added a short-term-rental floor — but it does not preempt CC&R restrictions on accessory dwellings. Conventional planned-unit-development HOAs outside the condominium framework are governed by general civil-code contract principles. Practical impact: in Puerto Rico's many condominium and gated-community contexts, ADU rights depend on the master deed.

State financing programs

Puerto Rico's primary public housing financing vehicle is the Puerto Rico Department of Housing (Departamento de la Vivienda, PRDOH), which administers HUD CDBG-DR and CDBG-MIT recovery funds tied to Hurricanes Irma and María (2017) and the 2019–2020 earthquake sequence. The flagship homeowner-side program is R3 — the Home Repair, Reconstruction, or Relocation Program — funded with $2.2B+ of the $10B in CDBG-DR funds HUD has allocated to Puerto Rico for hurricane recovery. R3 funds repair, reconstruction, or relocation for single-family homes damaged by qualifying disasters; ADU-equivalent accessory structures could be built as part of a qualifying reconstruction but the program is not ADU-targeted. The Puerto Rico Housing Finance Authority (Autoridad para el Financiamiento de la Vivienda, AFV) issues mortgage-revenue-bond first-mortgage financing for first-time homebuyers. Outside the disaster-recovery channels, there is no commonwealth-wide ADU-specific consumer loan or grant.

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.
