Building permits, zoning and septic rules in Highlands County, Florida

In unincorporated Highlands County, building permits are required for additions and structural changes, including moving an interior wall, and for specified electrical, plumbing, mechanical, window, door and roof-line modifications¹. The county also lists decks, fences, retaining walls, sheds, carports, accessory structures, concrete slabs and driveways as work requiring building permits¹. Interior cosmetic work typically does not need a building permit¹. Since July 1, 2026, certain single-family-home projects below $7,500 may qualify for an exemption, but require an exemption application and proof of value; structural, plumbing, electrical, fuel-gas and mechanical alterations and flood-zone projects are excluded¹. Highlands County administers the 2023 8th Edition Florida Building Code and lists the 2026 9th Edition as effective December 31, 2026¹³. The owner-builder contractor-licensing exemption requires personal signing, direct onsite supervision of unlicensed work and construction for the owner’s use rather than sale or lease; building permits and code compliance still apply¹⁴. Qualifying nonresidential farm buildings on bona fide agricultural land outside urban agriculture are exempt from building-code and local-code or fee requirements; floodplain rules still apply, and dwellings do not qualify¹¹.

The Highlands County Building Division is the first county office for building permits and inspections; its published contact is 501 S. Commerce Ave., Sebring, FL 33870, (863) 402-6643 and plans@highlandsfl.gov¹⁵. Homeowners and other public users can create a Public User Account in eTRAKiT to submit permits, licenses, inspection requests and planning reviews¹⁶. eTRAKiT holds county data from April 30, 2026 forward, while the older eGov portal holds data through April 29, 2026¹⁶. Inside Sebring, use the city’s residential building application¹⁷. In Lake Placid, obtain town zoning and/or engineering approval before taking the application to Highlands County for final building-permit issuance¹⁸. Septic permits remain with the Florida Department of Health in Highlands County under DEP’s statewide program⁶. Highlands County publishes fee schedules, but the exact building-permit charge depends on the service and project type, so confirm the amount with the Building Division^15,19.

Highlands County Planning & Zoning administers zoning in unincorporated Highlands County². Sebring, Avon Park and Lake Placid administer their own zoning inside municipal limits; county zoning rules below apply outside those limits^2,3,4,5. Septic permitting and inspections remain with the Florida Department of Health in Highlands County under DEP’s statewide program⁶. Use the county’s interactive zoning and land-use map to identify an unincorporated parcel’s district before asking Planning & Zoning about permitted uses and dimensions^7,20. The R-1 residential district sets a 750-square-foot minimum floor area; R-2 uses the same minimum, with 600 square feet allowed for the second unit under the same roof^21,22. EU Estate District residences need front and rear yards of at least 25 feet, side yards of at least 10 feet and a 15-foot corner side-street yard²³. Development review can include public water or sewer connections, but the rule does not require every residential parcel to connect²⁰.

Florida DEP enforces statewide septic laws, while the Florida Department of Health's local county health department issues Highlands County septic permits and handles inspections^6,24. Florida requires a permit to construct, install, modify, abandon or repair an onsite sewage treatment and disposal system, and the application requires a site evaluation²⁵. Environmental Health lists 863-386-6040 and 7205 South George Blvd., Sebring, FL 33875²⁶. Contact Environmental Health to arrange required septic inspections²⁶. None of Highlands County's mapped soil is rated free of severe limits for a conventional septic drain field, although 99.5% of county land has a slope of 15% or less¹². A flat-looking lot can still need careful evaluation and a more complex system design^12,25.

In unincorporated Highlands County, the county bars using a recreational vehicle for living, sleeping or business purposes in residential districts and in agricultural districts where the primary use is residential, except temporary sleeping and living for no more than 1 week in any 30-day period by a guest of the property owner or occupant⁹. In those districts, parked RVs generally may not sit in a front yard or within 7.5 feet of a side or rear lot line, with a 25-foot rule from street-abutting lines on corner, lakefront and pre-1971 nonconforming lots, and may not connect to central utilities except briefly for charging or repairs⁹. We could not confirm the rule in other zoning districts, so ask Planning & Zoning about the parcel⁷. A manufactured home must pass an onsite installation inspection and receive a certificate of occupancy, while local zoning, setbacks and site-development rules continue to apply²⁷. A tiny house must satisfy applicable permit and zoning rules; we could not confirm a special tiny-home permission^1,7.

1. Identify the parcel's zoning district and confirm the proposed use, setbacks, structure size and any utility-connection conditions with Highlands County Planning & Zoning^7,20.
2. If septic is needed, apply through the local county health department and complete the required site evaluation and inspection^6,26.
3. If a private well is planned, obtain the required well-construction permit before installation¹⁰.
4. Create the appropriate eTRAKiT account and submit the building-permit application to the Highlands County Building Division^1,15,16.
5. Ask Engineering whether the proposed county-road access needs a residential driveway permit; the Fiscal Year 2024-2025 engineering schedule lists $250 for a new residential driveway with one access, so confirm the current fee^1,28,29.
6. Confirm required building inspections and occupancy approval with the Building Division; projects subject to Fire Rescue’s occupancy process receive a certificate of occupancy after passing the final inspection^15,30.

Check the zoning district and permitted use before treating a parcel as buildable⁷. Check septic feasibility early because 0% of mapped soil is rated free of severe limits for a conventional drain field¹². Ask Planning & Zoning whether the proposal must connect to public water or sewer; county land-development requirements can include those connections, but the available rule does not impose them on every residential parcel^7,20. A private well needs a well-construction permit before installation¹⁰. Confirm legal access and ask Engineering whether driveway work in a county right-of-way needs a permit^1,29. Highlands County's typical effective property tax rate is 0.7%, and the median annual bill is about $1,295¹².
