ADU details
ADU legality: with-restrictions
Toa Baja second-dwelling work is governed by the 2024 RIPT plus RC-2023. Levittown / coastal parcels face FEMA AE/VE flood-zone constraints from Hurricane Maria 2017 storm-surge damage and chronic Rio de la Plata flooding (waist-high flooding 2017; major flood event approximately every 6 years per FEMA documentation).

Fee breakdown (as of 2026-04)
Permitting process
- Confirm Toa Baja parcel district under RIPT 2024 + RC-2023 (~4d)
Pull parcel sheet from Toa Baja municipal GIS. RIPT 2024 (OM-15-2024-2025) refined districts after public hearings - check post-2024 district designation. Toa Baja's barrios: Levittown (urbanizacion grid), Pajaros (coastal), Media Luna (inland mixed), Sabana Seca (south interior, US Naval Radio Transmitter site legacy), Toa Baja Pueblo, Candelaria, Palo Seco. - FEMA flood-zone determination - critical for Levittown / Pajaros / coastal parcels (~10d)
Pull parcel from FEMA Map Service Center. Levittown / Pajaros / lower Media Luna / coastal Palo Seco parcels are predominantly in AE storm-surge or A riverine flood zones. Base Flood Elevation Certificate required; foundation must be elevated to BFE or BFE+freeboard per RIPT. Hurricane Maria 2017 flooding precedent shapes municipal review. - Engage CIAPR-licensed architect or engineer (~21d)
Reglamento de Construccion CIAPR-licensed seal required. Toa Baja designers familiar with elevated-foundation work for Levittown reconstruction post-Maria. - Submit Permiso Unico via Single Business Portal (SBP) (~1d)
Filed at https://sbp.ogpe.pr.gov/. Toa Baja Oficina de Permisos receives Jerarquia I-III; OGPe central handles Jerarquia IV-V. Toa Baja's metro-area location means ready access to OGPe San Juan central. - DRNA Coastal Zone (ZMT) consultation - coastal Pajaros / Punta Salinas (~30d)
Coastal parcels trigger DRNA ZMT review. Punta Salinas (north of Levittown) is a popular beach/bird sanctuary requiring careful review. - PRASA water/sewer endorsement (~14d)
PRASA San Juan Metro Region serves Toa Baja. Levittown sanitary network was under stress post-Maria; capacity confirmation important. Sabana Seca interior parcels may be on private septic. - LUMA Energy interconnection request (~45d)
LUMA distribution from Toa Baja substations; service drop typical 30-60 days. - Construction inspections including flood-elevation verification
Toa Baja Oficina de Permisos inspectors plus engineer-of-record. Elevation Certificate at foundation; finished-floor verification at framing. Hurricane-tie continuous load path inspection. CMU lift inspections. - Permiso de Uso (Certificate of Use) issuance (~14d)
Final inspection plus Elevation Certificate triggers Permiso de Uso through OGPe; required before utility energization and any rental.
Viability (permitted uses)
- Long-term rental: yes (Codigo Civil de Puerto Rico (Ley 55-2020) landlord-tenant articles) Strong long-term rental demand from San Juan metro commuters; PR-22 and PR-165 access. Workforce housing for Bayamon hospital and government employment.
- Short-term rental: with-restrictions (Companias de Turismo de Puerto Rico STR Registry; Toa Baja municipal patente) Toa Baja STR market overshadowed by neighboring San Juan and Dorado high-end resorts. Price-sensitive STR niche exists in Levittown for budget travelers visiting San Juan area.
- STR registration with Companias de Turismo required
- Patente municipal required
- Levittown / Pajaros coastal STR demand modest - San Juan-adjacent mainland buyers default to San Juan or Dorado
- Punta Salinas beach access supports niche STR
- Office rental: with-restrictions Boulevard Marina commercial corridor allows mixed use; pure residential parcels require variance.
- Home office: yes Home occupation permitted with patente municipal.
- Studio / workshop: yes Personal art/workshop use permitted.
- Agriculture: with-restrictions (Sabana Seca rural barrios allow limited agriculture) Most of Toa Baja is coastal/urbanized; Sabana Seca and Media Luna interior preserve some agricultural use.
- Relative support: yes Family-occupancy second dwellings (la casita) common; many Levittown-grid lots have informal multigenerational arrangements.
Incentives
- R3 - Programa de Reparacion, Reconstruccion o Reubicacion (CDBG-DR) — Up to $150,000 reconstruction (when funded) (Levittown / Toa Baja owner-occupants damaged by Maria 2017 are a priority cohort given documented flooding)
- USACE Rio de la Plata flood control project — Federal flood-mitigation works (originally scoped 1980s, accelerated post-Maria) may produce future flood-zone re-mapping that lowers Levittown insurance burden and BFE elevation requirements.

Known issues (2)
- infrastructure (since 2017-09-20) — Levittown experienced waist-high storm-surge flooding during Maria 2017; municipality has suffered extreme flooding approximately every 6 years. USACE Rio de la Plata flood-control project ongoing. NFIP flood insurance and BFE elevation construction are practically mandatory in Levittown SFHA. (source)
- policy-review (since 2024-12) — OM-15-2024-2025 codified the Primera Revision Integral del Plan Territorial; first-year permit applications under refined district mappings may encounter case-by-case interpretation. Permit reviewers and applicants both adjusting to new layout. (source)
Dorado Municipio — county ADU rules and overlays
County ADU ordinance
Puerto Rico municipios are the territorial equivalent of US counties; this municipio applies the territory-wide ADU framework with local design overlays where applicable.
Puerto Rico state — ADU law and programs
State HOA preemption
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.
