Palm Beach County — county ADU rules and overlays
County ADU ordinance
Palm Beach County regulates accessory dwelling units on unincorporated parcels through the Palm Beach County Unified Land Development Code (ULDC), administered by Palm Beach County Planning, Zoning and Building Department. Palm Beach is Florida's third-most-populous county and geographically the largest county east of the Mississippi (~2,386 square miles), including Atlantic coastal cities (West Palm Beach, Boca Raton, Delray Beach, Palm Beach), suburban centers (Boynton Beach, Lake Worth Beach, Wellington, Royal Palm Beach, Palm Beach Gardens, Jupiter), and the agricultural Glades region in the west (Belle Glade, Pahokee, South Bay). § 163.31771 FS is permissive only; Palm Beach's ADU framework is local. The county is very HOA-dense — covenant restrictions on ADUs / rental occupancy materially shape practical ADU feasibility across most residential subdivisions.
- Palm Beach County Unified Land Development Code (ULDC)
- Florida Statutes § 163.31771 — Accessory Dwelling Units
State-floor overlay: No Florida statewide ADU preemption floor exists as of April 2026. SB 48 / HB 313 (2026 session) is the active preemption bill. Palm Beach retains full discretion until enactment.
County regulatory overlays
Palm Beach County administers flood, coastal, agricultural-preservation, airport, and water-management overlays that cut across jurisdictions. Coastal and Intracoastal parcels face extensive AE/VE flood mapping and CCCL exposure; the Glades-region agricultural-reserve overlay protects Lake Okeechobee-adjacent farmland from residential intensification; Palm Beach International Airport produces approach-zone constraints; the South Florida Water Management District (SFWMD) administers regional water-control and wellfield-protection overlays.
- FEMA Special Flood Hazard Areas (SFHA) — AE and VE zones are extensive along the Atlantic coast and Intracoastal Waterway. AE zones also occur in the Glades region along Lake Okeechobee and the C-series canals. ADUs in SFHA require elevation, flood vents, and flood-resistant materials.
- Coastal High Hazard Area (CHHA) — Atlantic-adjacent parcels fall within CHHA and face heightened comprehensive-plan review on intensification of residential use.
- Coastal Construction Control Line (CCCL) — Atlantic-front parcels seaward of the CCCL require state DEP permit in addition to county approval. Applies across much of the unincorporated oceanfront and through most incorporated beach cities.
- Agricultural Reserve (Ag Reserve) Overlay — A 22,000-acre Agricultural Reserve in central-west Palm Beach County protects farmland from urban encroachment and layers a 60/40 preservation-development ratio on parcels. ADU rights in the Ag Reserve are constrained by the preservation ratio and the rural-district standards of the Managed Growth Tier System.
- Palm Beach International Airport (PBI) Approach Zones — Parcels under PBI approach/transitional surfaces face height restrictions; a two-story ADU may require FAA Form 7460 notice.
- SFWMD Wellfield Protection & Water-Control — Parcels within mapped wellfield-protection zones face enhanced septic-siting review; SFWMD surface-water management rules apply to parcels impacting regional canals and water-control features.
- Wildland-Urban Interface (WUI) — Western and Glades-region Palm Beach parcels abutting undeveloped pine-flatwoods and scrub face moderate WUI exposure. Urbanized coastal Palm Beach has limited WUI exposure.
County permitting (unincorporated parcels)
Permits for ADUs on unincorporated Palm Beach County parcels are issued by Palm Beach County Planning, Zoning and Building Department. The county combines zoning, building, and floodplain review under one intake. Palm Beach's 38 incorporated municipalities each handle their own permits; unincorporated Palm Beach is substantial, particularly in the central and western agricultural Glades region and in large suburban pockets (Greenacres-area, Lake Worth-area, west Boynton).
Florida state — ADU law and programs
State ADU law
Florida does NOT currently have a statewide ADU preemption law in effect. Florida Statutes § 163.31771 (enacted 2004, last amended 2020) is permissive — it authorizes local governments to adopt ADU ordinances but does not require them to. ADU rules are therefore set municipality-by-municipality: Miami-Dade, Orlando, St. Petersburg, Tampa, and a growing set of Florida cities have their own ordinances; many smaller counties and cities still prohibit or restrict ADUs by default. A preemption bill (SB 48 / HB 313) is pending in the 2026 legislative session and is likely to pass given that its 2025 predecessor cleared the Senate 37-0 and House 97-10 before dying on a procedural amendment dispute.
- Florida Statutes § 163.31771 — Accessory dwelling units — Permissive (not mandatory) statute. Defines an ADU as 'an ancillary or secondary living unit, that has a separate kitchen, bathroom, and sleeping area, existing either within the same structure, or on the same lot, as the primary dwelling unit.' Authorizes — but does not require — local governments to adopt ordinances allowing ADUs in single-family residential zones. Contains no size caps, no owner-occupancy rules, no HOA preemption. All substantive rulemaking is local.
State financing programs
Florida Housing Finance Corporation (FHFC) does not operate an ADU-specific state loan or grant program. FHFC's primary affordable-housing lever at the ADU tier is the State Housing Initiatives Partnership (SHIP), which distributes state documentary-stamp-tax revenue to all 67 counties and 52 entitlement cities for locally-administered housing programs — some of which may fund ADU construction at the local level (notably Orange County's Affordable ADU Loan Program, run through the Orange County Housing Finance Trust). FHFC's FL Assist down-payment programs and HFA Preferred / HFA Advantage conventional loans apply to ADU-eligible primary residences but do not single out ADUs. Proposed CS/SB 1440 would create a state property-tax exemption of up to 100% of assessed value for an ADU rented at affordable rates.
State housing programs
Florida does not currently operate a statewide pre-approved ADU plan catalog (unlike California or Washington). State-level ADU implementation is driven by (a) the permissive § 163.31771 which lets willing jurisdictions adopt ordinances, (b) SHIP pass-through funding to local ADU programs (Orange County's Affordable ADU Loan Program is the model), and (c) the affordable-housing property-tax exemption under the Live Local Act (SB 102 / SB 328). The Department of Economic Opportunity (DEO) — now reorganized as the Department of Commerce — provides technical assistance to local governments but no statewide ADU-specific mandate or program. Major counties (Miami-Dade, Orange, Pasco, Hillsborough, Pinellas, Broward) have published their own ADU ordinances and guidance documents.
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.
