Puerto Rico

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.

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.

Puerto Rico's insurance regulator is the Office of the Commissioner of Insurance (Oficina del Comisionado de Seguros, OCS), an autonomous Government of Puerto Rico agency. Puerto Rico operates a JOINT UNDERWRITING ASSOCIATION (JUA) — the Puerto Rico Joint Underwriting Association for Fire and Allied Lines Insurance — established under 26 LPRA § 3702. The JUA is composed of every authorized fire-and-allied-lines insurer in Puerto Rico (membership is a condition of continued authorization to write any insurance business in PR) and provides residual-market capacity for residential and commercial property risks not placed in the voluntary market. Functionally the JUA serves the FAIR-Plan-equivalent role. Hurricane and earthquake exposure are Puerto Rico's dominant property-insurance risks; the post-María (2017) and post-2019/2020-earthquake market dislocations significantly increased premiums and prompted JUA usage. FEMA NFIP provides flood coverage; ADUs follow the parcel's flood-zone determination.
