Permitting process
- Confirm parcel jurisdiction (City of Arcadia city limits vs unincorporated DeSoto) (~1d)
City of Arcadia covers a compact downtown / antique-district footprint inside DeSoto County. Verify on the Property Appraiser map: Arcadia city limits trigger the City Development Services intake plus DeSoto County BD; unincorporated parcels go directly to DeSoto BD only. - City of Arcadia Development Services zoning review (Unified Land Development Code Article 4) (~10d)
Arcadia ULDC Section 6.13.00 governs 'Dwelling Units Accessory to Single-Family Detached Uses (Guest Houses)' and Article 4 sets zoning districts. Phone (863) 494-4114. Submit zoning clearance before building permit. Historic district overlay covers downtown antique blocks and triggers Historic Preservation review under ULDC Section 9103.17. - Submit DeSoto County building permit application (paper or Citizen Self-Service portal) (~1d)

Desoto County — county ADU rules and overlays
County ADU ordinance
DeSoto County (county seat Arcadia; inland south-central Florida) is a rural agricultural county (population approximately 34,000) with a primarily cattle, citrus, and agricultural economy. The county regulates accessory dwelling units on unincorporated parcels through the DeSoto County Land Development Regulations. Rural-residential and agricultural zoning districts generally permit accessory living structures, guest cottages, and caretaker residences subject to lot-size and setback conditions. Florida has no statewide ADU preemption; § 163.31771 FS is permissive only. Pending SB 48 / HB 313 (2026 session) would establish a statewide ADU floor with a December 1, 2026 conformance deadline if enacted.
State-floor overlay: Florida has no statewide ADU preemption as of April 2026. § 163.31771 FS is permissive only. Pending 2026 bills (SB 48 / HB 313) would impose a statewide floor; DeSoto's ordinance would need audit against the final statutory text if enacted (December 1, 2026 deadline in current drafts).
County regulatory overlays
DeSoto County administers a modest overlay portfolio appropriate to its inland rural location. The Peace River corridor bisects the county and creates extensive floodplain territory; South Florida Water Management District jurisdiction covers the entire county. Agricultural-use overlays and wildlife-habitat overlays (for gopher tortoise, crested caracara) affect some rural parcels.
- FEMA Special Flood Hazard Areas (SFHA) — DeSoto participates in NFIP. Parcels along the Peace River (which bisects the county north to south) and tributary corridors face Zone A or AE designations. Hurricane Ian (2022) produced catastrophic Peace River flooding that informed post-event map updates; much of Arcadia flooded. ADU construction in a mapped floodplain requires elevation-certificate review and can require substantial elevation.
- South Florida Water Management District Environmental Resource Permits — DeSoto sits within SFWMD jurisdiction. ADU site work affecting wetlands, adding impervious surface thresholds, or altering stormwater flow requires an ERP.
- Hurricane Wind Zone — approximately 140 mph ultimate design wind speed — DeSoto's inland-south location still places it in approximately the 140 mph ASCE 7-22 ultimate design wind-speed zone — central Florida's hurricane exposure (including Charley 2004 and Ian 2022) keeps inland wind loads high. Hurricane clips, roof-deck attachment schedules, and impact-rated openings or shutters are required.
- Florida Scrub-Jay, Gopher Tortoise, and Crested Caracara Habitat — Rural DeSoto contains mapped habitat for several listed species. Gopher tortoise is commonly encountered on sandy-upland parcels and requires FWC permitting for relocation if disturbed by construction. ADU site clearing on mapped habitat may trigger survey and relocation costs.
County permitting (unincorporated parcels)
Permits for ADUs on parcels in unincorporated DeSoto County are issued by the DeSoto County Building Department with zoning-compliance review from the Planning Department. Arcadia is the only incorporated municipality; the remainder of the county is unincorporated. Septic-system permitting for rural parcels is handled through the Florida Department of Health, DeSoto County office.
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.
