Shed permit exemption thresholds in Florida, plus the setback, tie-down and HOA rules that still apply to exempt structures.
Verified August 2026
What size shed can I build without a permit?
Often under 100-200 sq ft — but setbacks and tie-downs always apply
Many Florida jurisdictions exempt sheds under 100 to 200 square feet from a building permit, but zoning setbacks, hurricane tie-down requirements and HOA approval still apply. Some coastal jurisdictions permit every accessory structure regardless of size.
The exemption is about the building permit only
A permit exemption never exempts you from the rules themselves. Even an unpermitted shed must sit outside required setbacks and easements, must not exceed lot coverage limits, and in Florida must be anchored against uplift.
Common thresholds
Typical Florida patterns, which you must confirm locally:
- • Under 100 sq ft: frequently exempt from a building permit
- • 100 – 200 sq ft: exempt in some jurisdictions, permitted in others
- • Over 200 sq ft: permitted essentially everywhere
- • Any shed with electrical service: electrical permit required regardless of size
- • Any shed on a concrete slab: often triggers a permit for the slab
Tie-downs are not optional
Florida's wind loads apply to accessory structures. Prefabricated sheds usually come with an engineered anchoring detail — auger anchors or slab bolts — and inspectors will ask for it whenever a permit is involved.
Frequently asked questions
Can I put a shed on my property line?
Almost never. Accessory structure setbacks of 3 to 10 feet from side and rear lines are typical, and utility easements often push it further.
Does a shed increase property taxes?
A permanent, permitted structure can be added to the assessed improvement value. A portable resin shed usually is not.
