Levy County

Permits for ADUs on parcels in unincorporated Levy County are issued by the Levy County Building Department with zoning-compliance review from the Planning Department. Levy has eight incorporated municipalities (Bronson, Cedar Key, Chiefland, Fanning Springs, Inglis, Otter Creek, Williston, Yankeetown); most of the county is unincorporated. Septic-system permitting for rural parcels is handled through the Florida Department of Health, Levy County office.

Process overview: An ADU on an unincorporated Levy parcel is permitted as a building permit with zoning-compliance review. Typical workflow: zoning-compliance check, septic permit (if needed) through FDOH, construction-drawing submission under Florida Building Code 2023, plan review, wind-load review (Gulf-coastal Levy sits in approximately the 140 mph ASCE 7-22 ultimate design wind-speed zone; inland parcels 130-140 mph), issuance, inspections, and certificate of occupancy. Coastal parcels add FDEP CCCL review. Floodplain parcels (extensive along the Gulf coast, the Suwannee River, and the Waccasassa River) require elevation-certificate review.

Impact fees: Levy County levies modest impact fees. Transportation and schools fees are assessed on new residential units. ADU additions in unity-of-title configurations typically receive reduced rates. (schedule)

The Levy County Property Appraiser maintains parcel-level assessment records for all real property in Levy County. ADU additions are assessed at just value on completion; Florida's Save Our Homes 3% cap applies to homesteaded primary residences. Agricultural-classification (greenbelt) parcels retain agricultural use-value for the agricultural portion of the parcel even when an ADU is added to the homesite.

Assessment policy: ADU additions assessed at just value on completion; homesteaded host portion continues under Save Our Homes cap. Agricultural-classification parcels retain greenbelt valuation on the agricultural portion. No county-level ADU abatement or incentive.

Levy County administers coastal, floodplain, and wetland overlays. The Gulf coast from Yankeetown / Inglis in the south, through Cedar Key, to Horseshoe Beach (technically in Dixie County but adjacent) is highly low-lying and exposed to hurricane storm-surge. Hurricane Idalia (2023) made landfall on the Big Bend coast in neighboring Dixie / Taylor counties and produced catastrophic Cedar Key damage; Hurricane Helene (2024) added further impact. Suwannee River and Waccasassa River floodplains affect inland parcels. Suwannee River Water Management District jurisdiction covers the county.

• FEMA Special Flood Hazard Areas (SFHA) — Coastal A, VE, AE zones — Levy participates in NFIP. Coastal parcels on Cedar Key, in Yankeetown, Inglis, and along the extensive salt-marsh-backed Gulf shoreline face Zone VE or Coastal A designations. Post-Idalia (2023) and post-Helene (2024) map revisions raised base flood elevations in many coastal areas. ADU construction in Zone VE requires pile/column foundations, breakaway walls, and flow-through venting — Cedar Key's historic post-pile traditional construction already reflects these requirements.
• Coastal Construction Control Line (CCCL) — Parcels seaward of the CCCL on Cedar Key and along the Gulf shoreline require FDEP CCCL permits. Levy's extremely low-lying coastal profile means CCCL setbacks can significantly affect buildable area.
• Suwannee River Water Management District Environmental Resource Permits — Levy sits within SRWMD jurisdiction. ADU site work affecting wetlands, adding impervious surface thresholds, or altering stormwater flow requires an ERP. Coastal salt-marsh wetlands and inland river-floodplain wetlands are both common.
• Hurricane Wind Zone — approximately 140 mph ultimate design wind speed (Gulf coast) — Gulf-coastal Levy sits in approximately the 140 mph ASCE 7-22 ultimate design wind-speed zone; inland 130-140 mph. Hurricane Idalia (2023) and Helene (2024) have produced repeat-impact construction-cost pressure.
• Cedar Key Historic District — Cedar Key's historic district covers most of the main island and imposes architectural-compatibility review on new construction including accessory structures. This is a city-level overlay within Cedar Key; unincorporated Cedar Key adjacent areas do not have a county historic overlay.
• Waccasassa Bay Preserve State Park and Big Bend Seagrasses Aquatic Preserve — Waccasassa Bay Preserve and the Big Bend Seagrasses Aquatic Preserve cover a significant portion of Levy's Gulf coastline and adjacent waters. ADUs on parcels adjacent to these protected areas face additional water-quality and habitat-compatibility review.
