Bay County — county ADU rules and overlays
County ADU ordinance
Bay County regulates accessory dwelling units on unincorporated parcels through the Bay County Land Development Regulations (LDR), administered by the Bay County Planning and Zoning Division. Bay is a Florida Panhandle county on the Gulf of Mexico, home to Panama City, Panama City Beach, Lynn Haven, Callaway, Parker, Mexico Beach, and Springfield. The county was ground zero for Hurricane Michael (Oct 2018), which made landfall at Mexico Beach / Tyndall AFB as a Category 5 hurricane and produced catastrophic damage across Bay and neighboring counties. Rebuilding activity remains substantial as of April 2026 — many parcels are still in post-Michael reconstruction. § 163.31771 FS is permissive only; Bay's ADU rules are local.
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. Bay retains full discretion until enactment.
County regulatory overlays
Bay County administers flood, coastal, CHHA, and military-base AICUZ overlays. Gulf-front and St. Andrews Bay-adjacent parcels face extensive AE/VE flood mapping and CCCL exposure; Tyndall Air Force Base (east of Panama City) produces federal AICUZ overlays. Post-Michael, Bay adopted enhanced wind-load and elevation standards under an updated FBC Panhandle amendment.
- FEMA Special Flood Hazard Areas (SFHA) — AE and VE zones are extensive along the Gulf coast, St. Andrews Bay, West Bay, North Bay, and East Bay. ADUs in SFHA require elevation, flood vents, and flood-resistant materials; VE zones require pile-foundation construction. Post-Michael, FEMA revised flood-zone boundaries across Bay and the county adopted 1-2 feet of freeboard above BFE.
- Coastal High Hazard Area (CHHA) — Coastal Bay parcels fall within CHHA and face heightened comprehensive-plan review on intensification of residential use.
- Coastal Construction Control Line (CCCL) — Gulf-front Bay parcels seaward of the CCCL require state DEP permit in addition to county approval.
- Tyndall Air Force Base AICUZ — Air Installation Compatible Use Zones around Tyndall AFB restrict residential intensification in mapped APZ areas and require noise-attenuation construction in noise zones. Affects east-Bay parcels; ADUs in APZ areas may be prohibited.
- Northwest Florida Water Management District (NWFWMD) Wellhead Protection — Parcels within mapped wellhead-protection zones face enhanced septic-siting review.
- Wildland-Urban Interface (WUI) — Bay's extensive pine-flatwood and longleaf-pine forests abutting residential development produce meaningful WUI exposure. Post-Michael, many damaged forest tracts entered a prolonged regrowth phase with elevated fuel loads that raise practical wildfire risk beyond typical coastal-Florida baselines.
County permitting (unincorporated parcels)
Permits for ADUs on unincorporated Bay County parcels are issued by the Bay County Planning and Zoning Division. Incorporated municipalities — Panama City, Panama City Beach, Lynn Haven, Callaway, Parker, Mexico Beach, Springfield — each handle their own permits. Unincorporated Bay includes large tracts of the St. Andrews peninsula, the rural east and north, and the Sand Hills region.
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.
