Hardwood Floor Refinishing in Orlando, FL

Verified against official sources · Updated 2026-07-20

Thinking about refinishing a hardwood floor 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?

It depends on the exact scope. Orange County and the City of Orlando require permits for more than most homeowners expect — and the rules change. Check the county's official "Do I Need a Permit?" page or call your local building department before starting work.

Orange County and the City of Orlando run separate permit offices with separate portals — and your mailing address alone doesn't tell you which one covers your home. Check which permit office covers your address →

Key facts before you start

Engineered wood: measure the wear layer BEFORE planning a sand — at a floor-register cut, under a transition molding, or in a board gap down to the top of the tongue. NWFA's Sand and Finish Guidelines: in general, if wear thickness is less than 2.5 mm (3/32"), the floor should not be sanded at all. A full sand-and-finish OPERATION (the whole multi-grit job, not one pass) removes under 1/32", so a 4/32" unfinished engineered floor lands near 3/32" after its first site finish — still refinishable, not used up. (NWFA)
Recoat prep decides adhesion, and it is product-specific, not generic scuffing. Bona Traffic HD: the floor must be free of wax, polish and oily residues; with contaminants present you need the full Bona Recoat System (Remover + Rinse + PowerScrubber + Recoat Abrasive on a 175 rpm rotary buffer), while a clean poly floor uses Bona Prep. 'Adhesion failure can occur if these recoating processes are not followed, and the floor has not been tested for compatibility' — test an inconspicuous area first. Suspected wax or oil soap = contractor job, not a DIY scuff-and-coat. (Bona)
Cure is not dry. Bona Traffic HD (TDS rev. 05/27/2026): each coat dries 2-3 hr; cure is ~3 days (80% at 1 day, 100% at 3). Walkable at 24 hr but it 'remains susceptible to scuffing or marring until completely cured,' and 'do not replace area rugs until the floor has fully cured.' Older sheets said 7 days and are still widely quoted online — 3 days is the current figure. (Bona)
Run the A/C while finishing. Bona Traffic HD's stated application conditions are 65-80F and 40-60% RH, and 'high humidity and/or low temperature will extend the dry time' past the 2-3 hr between coats — an unconditioned Orlando house in summer sits well outside that. NWFA separately recommends holding the home at 60-80F and 30-50% RH year-round because moisture GAIN is what cups boards; target the 40-50% overlap and both are satisfied. (Bona / NWFA)
Oil-based stain rags AND the sanding residue self-heat and can ignite with no spark — the failure mode is material piled, wadded, or bagged where heat cannot escape. Minwax DANGER text: 'Immediately place rags, steel wool, other waste soaked with this product, and sanding residue in a sealed, water-filled, metal container.' The accepted alternative is laying rags flat and separated on a non-combustible surface, away from the structure, until fully cured — never a wad in a trash bag. Do not leave stain-loaded dust in a sealed shop-vac canister overnight. (Minwax)
Permit: unincorporated Orange County lists 'installation or replacement of finished floor covering' among minor repairs needing NO permit. Refinishing an existing floor is not named on that list — it is generally treated as exempt finish work, so confirm rather than assume, and that list governs unincorporated county only (Orlando, Winter Park, Windermere, Apopka, Ocoee, Maitland and Winter Garden each run their own department). The exemption ends the moment you go past the surface: subfloor or joist repair, wet-area waterproofing, or moving plumbing/electrical all require a permit.
