The Rule That Surprises Most Homeowners
Florida Building Code Section 105.1 requires a permit for any "construction, erection, alteration, repair, demolition, or change of occupancy of a building or structure." The question is: does a flooring installation qualify as an "alteration"?
In Palm Beach County, the answer hinges on two factors: whether the structural subfloor is altered and whether the finished floor height changes by more than a certain threshold. Here is the breakdown homeowners need to understand before hiring anyone.
When a Permit Is NOT Required
You generally do not need a permit in Palm Beach County for flooring work that meets all of the following conditions:
- Direct replacement of like-for-like floor covering — removing carpet and installing LVP, or replacing existing tile with new tile at the same height
- No structural subfloor work — the plywood, OSB, or concrete slab underneath is not cut, replaced, sistered, or modified
- No change in floor system height exceeding ½ inch — adding a thick mortar bed under tile, or stacking underlayment, can push the finished floor up and create a permit trigger
- No wet area waterproofing membrane work in bathrooms that involves a penetration into the slab or wall framing
Example: Removing carpet from a bedroom and installing LVP with a thin underlayment — no permit required in most Palm Beach municipalities.
When a Permit IS Required
You need a permit in Palm Beach County when the flooring project involves:
- Bathroom tile with a mud bed (mortar bed) system — particularly when the mud bed requires saw-cutting the slab for a recessed shower pan
- Subfloor replacement or sistering — if water damage or rot requires replacing plywood subfloor panels, this is structural work requiring a permit
- Raising or leveling the floor system — self-leveling compound applied over 1 inch thick or sleeper systems installed on slab require permits in many Palm Beach jurisdictions
- Radiant in-floor heating — any electrical work embedded in the floor assembly requires an electrical permit
- Slab saw-cutting — opening the slab for any reason triggers both a permit and an inspection
Important: Permit requirements vary by municipality within Palm Beach County. Boca Raton, Delray Beach, West Palm Beach, and Boynton Beach each have their own Building Departments with slightly different thresholds. What's exempt in unincorporated Palm Beach County may require a permit within city limits.
The Insurance and Home Sale Risk
This is where homeowners make a mistake that costs them tens of thousands of dollars. If you complete flooring work that required a permit without pulling one, you create two serious exposures:
Homeowner's Insurance
If a bathroom floor fails due to water infiltration and the underlying waterproofing work was done without a permit, your homeowner's insurance carrier has legal grounds to deny the claim. This is not a theoretical risk — it happens in South Florida regularly, especially with aging bathroom tile installations where the original waterproofing was never inspected.
Home Sale Disclosure
Florida law requires sellers to disclose known unpermitted work. When a buyer's inspector flags unpermitted flooring work, you either pull an after-the-fact permit (expensive and uncertain) or negotiate a price reduction. In a high-end Palm Beach market, unpermitted work can cost you $15,000–$40,000 at the closing table.
What a Licensed GC Does Differently
An unlicensed handyman has no legal ability to pull permits in Palm Beach County. A licensed General Contractor (CGC license) can pull every permit category relevant to a flooring project — building, electrical for heated floors, and plumbing if any floor drains are involved. We handle the entire permit cycle: application, inspection scheduling, and final sign-off.
The permit itself typically costs $100–$350 for a residential flooring project in Palm Beach County. The licensed contractor fee to manage the permit process is built into our quote. There is no separate line item.
Common Projects and Their Permit Status
- LVP throughout entire home (replacing carpet/vinyl) — Typically no permit required
- Porcelain tile in kitchen (replacing existing tile, same height) — Typically no permit required
- Full bathroom remodel with new shower tile and pan — Permit required in virtually all Palm Beach jurisdictions
- Shower only: re-tile over existing waterproofed substrate — Varies by jurisdiction; consult your municipality
- Subfloor replacement after water damage — Permit required
- In-floor heating system installation — Electrical permit required
"The contractors who tell you 'you don't need a permit for this' without actually looking at your scope of work are the ones protecting their schedule — not your property. We've pulled after-the-fact permits for homeowners whose previous contractors skipped them. The cost to retroactively permit work that's already in the wall or floor is always higher than doing it right upfront — because the inspector can require you to open up the work for access."
