Do you need a building permit in Hernando County, Florida?

Hernando County requires a building permit for most construction-related work, including residential construction; some home improvements and maintenance are exempt, but exempt work must still meet code and zoning setbacks1. The statewide base is the Florida Building Code, 8th Edition (2023), as updated by the Florida Building Commission11. A qualifying owner may act as the contractor, but must appear personally, sign the application, build for the owner's own use rather than sale or lease, supervise the work on site, and meet licensing, employment, tax and workers' compensation conditions5. Occupancy or use must wait until the Building Division issues a Certificate of Occupancy or Certificate of Completion12.

Who is the Hernando County building department, and how do you reach them?

Hernando County's Building Division is the first stop for building permits, plan review and inspections13. Reach the division at (352) 754-4050, email [email protected], or visit 789 Providence Boulevard, Brooksville, FL 3460113. Permit fees vary because Florida law leaves reasonable fee amounts to the enforcing agency, so request the current fee for the exact scope of work rather than relying on a generic estimate14. Before filing, ask the Zoning Division to confirm the parcel district and dimensional rules; Zoning can be reached at (352) 754-4048 or [email protected] at 1653 Blaise Drive, Brooksville, FL 346019.

Does Hernando County have zoning?

Unincorporated Hernando County is subject to county zoning administered by the Zoning Division, which reviews residential and commercial site plans2. The practical answer is parcel-specific: each district has its own permitted uses, setbacks and dimensional requirements, and Planned Development Project districts may have customized uses and setbacks3. Hernando County's ordinance regulates minimum lot size, setbacks and maximum building height, but the available rules do not establish one countywide number for any of them678. Ask Zoning for a parcel-specific determination before choosing a house plan, accessory structure or second dwelling9. Municipal ordinances may differ inside incorporated places, so do not apply the unincorporated-county answer to a city parcel3.

How do septic permits work in Hernando County?

Florida DEP implements the statutes and regulations for onsite sewage systems, while the Florida Department of Health in Hernando County continues septic permitting and inspections4. New installations, repairs, modifications and approvals of existing systems require a permit from the local health department15. Reach Environmental Public Health at 352-540-6812, email [email protected], or visit 7551 Forest Oaks Blvd, Spring Hill, FL 3460615. A statewide site evaluation determines property conditions and system suitability before an onsite sewage permit is issued16. Only about 4.5% of county soils are rated without severe limits for a conventional drain field, so make the site evaluation an early feasibility check rather than assuming a standard system will fit17.

Can you live in an RV or tiny home on your land in Hernando County?

We could not confirm Hernando County's rules for long-term RV occupancy, temporary camping or tiny-home occupancy on private land, so ask the Zoning Division about the exact parcel and proposed use before buying or moving a unit onto it9. Florida's rules for licensed recreational vehicle parks and camps do not answer whether an owner may live in an RV on private land outside one of those facilities1819. A manufactured home follows a different process: state installation standards require an onsite inspection before a certificate of occupancy, while local zoning, setbacks, fire-zone and subdivision requirements still apply20. Hernando County also requires the appropriate Certificate of Occupancy or Completion before a structure may be occupied or used12.

Building a home in Hernando County: the steps, in order

  1. Ask the Zoning Division to verify the parcel's district, permitted use, minimum lot size, setbacks, height limit and flood-zone status36789.
  2. Confirm legal access; a Class D division needs county Public Works approval for driveway location, while access to a state highway needs a Florida Department of Transportation permit21.
  3. Obtain the septic site evaluation and permit through the Florida Department of Health in Hernando County1615.
  4. Choose a licensed contractor or confirm that the owner-builder conditions fit the project5.
  5. Apply to the Building Division for the required construction permit and complete inspections113.
  6. Do not occupy or use the structure until the Building Division issues the required Certificate of Occupancy or Completion12.

What to check before you buy land in Hernando County

Check zoning, access, septic suitability and floodplain status before treating a Hernando County parcel as buildable. Development in a Special Flood Hazard Area is regulated with the Florida Building Code, and the permit record may need elevation documentation such as an Elevation Certificate10. If the sale involves splitting one parcel into two through the Class D process, the parent parcel must front a county-owned and maintained right-of-way, driveway location needs Public Works approval, and access to a state highway needs a state transportation permit2221. Only about 4.5% of county soils are rated without severe limits for a conventional septic drain field17. Water-well construction, repair or abandonment requires a permit from the appropriate water management district or delegated authority, so identify that authority before budgeting a well23.

Watch-outs

  • A building-permit exemption does not waive Hernando County's minimum code standards or zoning setback requirements1.
  • Do not assume a large or rural-looking parcel can be split freely; Hernando County regulates Class D divisions and requires access review2221.
  • Floodplain rules still apply to qualifying nonresidential farm buildings even when Florida's agricultural building exemption otherwise applies24.
