Indian River County — county ADU rules and overlays
County ADU ordinance
Indian River County is an Atlantic-coast central-Florida county (population ~167,000, Vero Beach is the county seat) with a mix of coastal residential, agricultural citrus heritage, and growing suburban development. The county is a non-charter commission government. The Indian River County Land Development Regulations (LDRs, Title IX of the county code) govern unincorporated land use; the county has five municipalities (Vero Beach, Sebastian, Fellsmere, Indian River Shores, Orchid). The LDRs contain specific accessory-dwelling provisions — Section 911.11 recognizes 'accessory residential structures' and 'guest quarters' as permitted accessory uses in several residential districts (RS-1, RS-2, RS-3, RS-6) subject to size limits (typically 50% of main dwelling or 800 sqft maximum), shared-utility requirements, and owner-occupancy expectations. The LDRs DO NOT align with the model Florida s 163.31771 language but represent a more developed ADU framework than many rural FL counties. No pending ADU rulemaking as of 2026-04-20.
County regulatory overlays
Indian River County overlays relevant to ADU siting: (1) FDEP Coastal Construction Control Line along the ~22 miles of Atlantic coastline and associated barrier-island development; (2) FEMA SFHAs with Zone VE on the barrier island, Zone AE along the Indian River Lagoon, St. Sebastian River, and coastal creeks; (3) Indian River Lagoon Basin Management Action Plan (BMAP) — the lagoon is severely impaired and BMAP imposes fertilizer, stormwater, and septic upgrade requirements county-wide (via SJRWMD and FDEP); (4) Pelican Island National Wildlife Refuge (the nation's oldest NWR, est. 1903) and Archie Carr National Wildlife Refuge (sea turtle nesting on Atlantic coast) — federal overlays; (5) Florida Building Code 150+ mph design-wind-speed region (non-HVHZ Atlantic coast hurricane zone); (6) historic citrus-grove / agricultural legacy overlays protecting some rural lands under the Comprehensive Plan.
- FDEP Coastal Construction Control Line (CCCL)
- FEMA SFHAs — coastal VE/AE and lagoon AE
- Indian River Lagoon Basin Management Action Plan (BMAP)
- Pelican Island National Wildlife Refuge + Archie Carr NWR
- Florida Building Code 150+ mph design-wind-speed (Atlantic coast)
- Citrus Greenbelt Overlay and Comprehensive Plan rural/agricultural designations
County permitting (unincorporated parcels)
Most of Indian River County's developable area outside the cities (including the unincorporated Wabasso, Roseland, and much of the mainland west of I-95) is permitted by the Indian River County Community Development Department — Building Division at the County Administration Complex in Vero Beach. IRC uses the Florida Building Code as adopted; the county operates an Accela-based ePermits portal (CentralSquare / Energov) for intake, plan review, and inspections. Typical single-family / accessory-dwelling permit review runs 3-5 weeks. Coastal barrier-island parcels (portions of the mainland east of the Indian River Lagoon and small communities on the barrier island) require FDEP CCCL review for seaward-of-CCCL siting.
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.
