Hillsborough County, Florida handles permits for unincorporated areas — the vast suburban and rural areas outside Tampa, Temple Terrace, and Plant City. The county's Development Services Department at 601 E. Kennedy Blvd. handles residential permits through an online portal at hcfl.gov/business/permits.
The shed threshold in Hillsborough County is 120 sq ft, the same as Orange County. Sheds 120 sq ft and under are permit-exempt but must meet setback requirements. All decks attached to the primary structure require a permit. Fences under 6 feet generally don't require a permit but must meet zoning rules.
Hillsborough County has invested significantly in its online permitting portal. Most residential permits can be applied for, reviewed, and approved entirely online without an office visit. Permit fees: shed permits $50–$120, deck permits $75–$175. Review times are 3–7 business days for simple residential projects.
