Wood Fence Repair repair in Orlando, FL

Verified against official sources · Updated 2026-07-06

Thinking about a wood fence repair repair in the Orlando area? Here's what actually matters — permit rules for Orange County and the City of Orlando, plus the mistakes and code requirements that trip up homeowners, sourced from manufacturer manuals and the Florida Building Code.

Do you need a permit?

Check with your building department. Replacing a few pickets/panels like-for-like has no published exemption in Orange County — confirm with Zoning before large sections.

Key facts before you start

Post hole spec (Quikrete): diameter = 3x post width (12 in. for a 4x4), depth = 1/3 to 1/2 of the post's above-ground height PLUS 6 in. for a compacted gravel base — the gravel is the drainage layer under the concrete, don't skip it. A 6-ft fence needs a ~2-ft embedment.
Quikrete Fast-Setting no-mix method: pour the DRY mix straight into the hole around the braced/plumbed post, then add water on top — no mixing. Sets in 20-40 min but do NOT hang panels or apply heavy load for 4 hours.
Top of the concrete footing must shed water: either crown/slope it above grade away from the post, or stop it 3-4 in. below grade and backfill with soil. A flat concrete collar at grade ponds water against the post — the #1 cause of repeat rot in FL.
Posts must carry an end tag reading AWPA U1, UC4A (Ground Contact) minimum — spec UC4B (Ground Contact Heavy Duty) for hard-to-replace or high-decay settings like Central FL. 'Above ground' (UC3B) treated lumber rots fast when buried; pickets/rails can be UC3B, posts cannot.
A post rotted at the grade line has lost its structural section where bending load is highest — replace full-depth to the embedment spec; a sistered stub bolted above grade can't restore the 1/3-1/2 embedment and will lean again in the next storm.
FL wind: FBC 1616.2.1 lets fences up to 6 ft from grade be designed for 115 mph 3-second gust; anything over 6 ft needs engineered design. Orange County: new wood fences up to 6 ft take a Zoning fence permit (site plan/survey, ~$38 base, 4-day review); over 6 ft or masonry = building permit; like-for-like repair in the same footprint/style may be exempt — check the app's permit table repair-vs-new line.
