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

Hillsborough County requires approval and permits from Building Services for most construction1. Cosmetic work may be exempt, including cabinet work, floor coverings, painting, shelving, tile, wallpapering and some fencing, while the details of bathroom or kitchen work determine whether a permit is needed1. The county's construction code incorporates the Florida Building Code, but the county page still refers to the 2014 edition while Florida has adopted the 8th Edition (2023), as subsequently updated1011. Ask Development Services which current code provisions apply to the proposed work rather than relying on the older edition named on that county page12.

Who is Hillsborough County Development Services, and how do you reach them?

Hillsborough County Development Services combines planning, zoning, development review and building inspection for unincorporated Hillsborough County2. The office is at 601 E. Kennedy Blvd., Tampa, FL 33602, and its phone number is (813) 272-5600122. Building applications are submitted through HillsGovHub with the required documents13. Filing an application does not create a permit: county review and approval, along with payment of applicable fees, must occur before issuance13. After issuance, required inspections are scheduled through HillsGovHub; the county can issue a Certificate of Occupancy after those inspections and fee payments are complete13.

Does Hillsborough County have zoning?

Hillsborough County zones unincorporated land through its Land Development Code, administered by Development Services62. Standard zoning districts take their development standards, including height and setbacks, from the Land Development Code; Planned Development districts use their approved plans and conditions1415. Community Planned Development and Special Overlay District areas may also require architectural design review14. The Land Development Code regulates site development and subdivision as well as zoning, although the reviewed material does not establish a parcel-specific subdivision threshold7. Before buying, ask Development Services for the parcel's district, applicable planned-development conditions, setbacks and any subdivision or site-development review2.

How do septic permits work in Hillsborough County?

The Florida Department of Health in Hillsborough County handles septic construction permitting and inspection4516. The office publishes separate application packages for new construction, existing-system modification, repair, abandonment and holding tanks4. Applications may be delivered by hand, mail, fax or email; faxed or emailed submissions require credit-card authorization or telephone payment4. Existing-system inspection and assessment is listed as voluntary, while construction and certain operating systems have inspection requirements5. Only about 0.1% of county soils are rated without severe limitations for a conventional drain field, so make the site evaluation an early feasibility step rather than assuming a conventional system will work17.

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

We could not confirm a general Hillsborough County right to live long term in an RV or tiny home on private land. Florida's rules for transient stays in permitted RV parks do not answer whether an RV may be occupied on a private parcel outside such a park18. Tiny-home occupancy, temporary private-land camping, minimum dwelling size and minimum lot size also could not be confirmed as countywide rules. Because unincorporated land is zoned and parcel standards vary by district or Planned Development approval, ask Development Services about the specific parcel and proposed use before buying or moving a unit onsite6142.

Building on land in Hillsborough County: the steps, in order

  1. Confirm the parcel's zoning district, setbacks, planned-development conditions and subdivision constraints with Development Services1572.
  2. Determine the correct septic application and submit it to the Florida Department of Health in Hillsborough County; treat soil and site feasibility as an early decision417.
  3. Submit the building application and supporting documents through HillsGovHub13.
  4. If acting as your own contractor, file the Owner Builder Disclosure Statement; the property must be in your name and be your primary residence, and it cannot be sold for one year after completion3.
  5. Wait for review and approval and pay the applicable fees; an application alone is not an issued permit13.
  6. After issuance, schedule required inspections through HillsGovHub; complete inspections and fee payments before the Certificate of Occupancy13.

What to check before you buy land in Hillsborough County, Florida

Start with septic feasibility because only about 0.1% of Hillsborough County soils are rated without severe limitations for a conventional drain field17. Water-well construction, repair or abandonment requires a permit from the appropriate water management district or delegated authority, but the county well information reviewed here is specifically for public drinking-water wells rather than a single home's private well1920. Confirm private-well details, utility availability and any sewer-connection requirement for the parcel before closing. Also verify zoning, setbacks and subdivision constraints with Development Services because the applicable standards can depend on the zoning district or Planned Development approval1572. For carrying costs, the effective property-tax rate is about 0.8%, the median annual bill is about $2,787, and the typical annual home-insurance premium is about $3,2128921.

Watch-outs

  • Submitting a building application does not authorize construction; wait for approval, issuance and fee payment before starting work13.
  • The owner-builder route requires an Owner Builder Disclosure Statement, a primary residence held in the homeowner's name and no sale for one year after completion3.
  • We could not confirm long-term RV occupancy, tiny-home occupancy or temporary camping on a private parcel; ask Development Services about the parcel and proposed use62.
  • The county's published well information covers public drinking-water wells, while statewide rules route water-well permits through the appropriate water management district or delegated authority; confirm the private domestic-well process before budgeting2019.

Water rights & wells in Hillsborough County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Florida’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

F.S. 373.219(1): 'no permit shall be required for domestic consumption of water by individual users.' The exemption holds statewide, including inside every Water Use Caution Area and the CFWI. A well-construction permit is still required, but that is a construction/quality gate, not a quantity allocation.

Limit: individual single-family domestic use exempt (no CUP/WUP)

Florida Statutes 373.219(1) & 373.019 ↗
  • Northern Tampa Bay Water Use Caution Areamajority of county

    Regional public-supply withdrawals (11 wellfields) capped at/below 90 mgd with wetland/lake/spring MFLs. A new household well remains exempt; the cap governs the regional utility, not homeowners.

  • Southern Water Use Caution Area (SWUCA)partial of county

    Minimum aquifer levels breached; a 20-year Recovery Strategy (2006) caps PERMITTED withdrawals against saltwater intrusion. A new single-family domestic well remains exempt — the caps bind large permitted users only.
