Yes, you need a permit to build a deck in Hernando County. Nearly every deck attached to a home — and most freestanding ones — requires a building permit, engineered drawings and county inspections. Here's the whole process, what it costs, and why skipping it is the most expensive shortcut in home improvement.
Which Decks Need A Permit
- Any deck attached to the house — the ledger connection alone makes it structural work
- Elevated decks — anything with meaningful height, stairs or railings
- Pool-adjacent decks — these also trigger Florida's residential pool barrier code
- Covered decks and screened lanais — roof structures always require permits and engineering
- Structural repairs — replacing joists, beams or posts (board-for-board surface replacement generally doesn't)
Very low freestanding platforms can sometimes qualify for an exemption, but the threshold is narrow — confirm with the county before assuming, because "I thought it was exempt" is not a defense code enforcement accepts.
The Process, Step By Step
1. Drawings and engineering. Site plan, framing plan and wind-load calculations showing the deck meets Florida Building Code for Hernando County. This is where footing depth, post sizing and hurricane hardware get specified.
2. Submission. The package goes to the Hernando County Building Division in Brooksville (or through the online portal). Straightforward decks typically see approval in 1–2 weeks.
3. Inspections during the build. Footings get inspected before concrete is poured, framing before decking goes down, and a final inspection closes the permit. Fail any of them and work stops until corrected.
4. Permit closure. The passed final inspection is your proof — keep it. It's what your insurer and a future buyer's title company will want to see.
What It Costs
County permit fees for a typical residential deck run $150–$400. Add drawings and engineering and the full permitting line item is usually $500–$1,200. Every quote we write includes it — when comparing contractors, ask directly, because a suspiciously low bid often means the permit "wasn't included."

What Happens If You Skip It
Insurance: after a storm, carriers investigate. Damage involving an unpermitted structure is a textbook claim denial — in a county that sees named storms, that's real money on the table.
Selling the house: unpermitted additions surface in inspections and title work. Buyers walk, lenders balk, or you fund retroactive permitting — which can mean opening up finished work so the county can inspect framing that was never approved.
Code enforcement: a complaint or a drive-by is all it takes. The county can issue daily-accruing fines and require removal of the structure entirely.
The permit isn't bureaucratic friction — it's what makes your deck a documented, insurable, sellable asset instead of a liability bolted to your house.
