Do I Need a Permit to Remodel My Bathroom in St. Petersburg?
Yes, if the remodel touches plumbing, wiring, walls or anything structural, because Florida law requires a permit to alter a building and St. Petersburg exempts only finish work like tile, cabinets, countertops and paint, plus swapping a fixture in the same spot. Since July 1, 2026, owners of single-family homes can also skip the permit on other work under $7,500 by filing an exemption request first, but that option is closed to any property in a flood hazard area and to any plumbing, electrical, mechanical, gas or structural work.
What needs a permit
St. Petersburg's building department applies the Florida Building Code rule: anyone who intends to construct, alter or repair a building, or to install, alter, remove, convert or replace an electrical, gas, mechanical or plumbing system, needs a permit first. In a bathroom that means moving a toilet, tub, shower or sink, adding or moving circuits, replacing a water heater, or taking out or adding a wall. Replacing the bathroom window counts too, since the city lists window and door replacement as structural work.
Plumbing Relocation
Moving a toilet, tub, shower, or sink to an alternate floor location requires drain-waste-vent modifications and city rough-in inspection.
Electrical Circuits
Adding or moving electrical circuits, adding dedicated 20-amp circuits for vanities, or installing dedicated high-draw appliances and heated floors.
Water Heater Replacement
Replacing a dedicated hot water tank or tankless unit is strictly excluded from finish-work exemptions due to gas, electrical, and pressure relief valve mandates.
Partition & Structural Walls
Taking out or constructing a wall even non-bearing division partitions requires building review for fire safety ratings, framing anchorage, and egress clearances.
Bathroom Window Replacement
St. Petersburg explicitly classifies exterior door and window replacements as structural building envelope alterations requiring wind-load product approval.
Pinellas County Code Compliance
Work performed without permits creates chain-of-title clouds during resale, invalidates homeowners insurance coverage during leaks, and incurs triple permit penalty fees.
What the City Exempts
Some bathroom finish work does not require a permit in St. Petersburg, as long as it doesn’t affect a load-bearing wall or a fire-rated wall or ceiling. Here are the most common examples.
Finish Work That May Be Exempt
Cabinets & vanities
Same-footprint installation without changing plumbing.
Countertops & decorative hardware
Counters, mirrors, towel bars and cabinet hardware.
Tile, painting & carpeting
Finish work that doesn’t affect a load-bearing wall or a fire-rated wall or ceiling.
Minor wall repairs
Replacing an existing sink or toilet without moving pipes or valves.
Minor wall repairs
Patching up to 100 sq. ft. of interior wall or ceiling finish.
Keep in Mind
Structural or fire-rated elements
Altering or demolishing load-bearing walls or fire-rated assemblies requires a permit.
Water heaters
Water heaters are not exempt, even when replacing one in the same location.
Historic districts
Homes in a local or national historic district may not get these exemptions.
If you’re unsure whether your project qualifies, check with the City of St. Petersburg or a licensed contractor before starting work.
The new $7,500 exemption
Statutory Single-Family Exemption Cap (HB 803 / FS 553.79)
Effective statewide as of July 1, 2026. Regulates minor residential projects across municipal building jurisdictions.
A state law that took effect July 1, 2026 (Florida Statute 553.79, as amended by House Bill 803) requires every local government to exempt single-family owners and their contractors from permits for work valued under $7,500. It doesn't apply to any property partly or entirely in a flood hazard area, or to electrical, plumbing, structural, mechanical or gas work, and splitting one project into smaller ones to stay under the limit isn't allowed. St. Pete handles it with a Permit Exemption form that lists the scope and total value, signed in front of a permit technician or a notary, and work already on the city's exempt list doesn't need the form. Exempt work gets no permit and no city inspection, and the same law says the local government has no legal duty to the owner or contractor for it.
Requirements & Process
Permit Exemption form filed with detailed scope & total project value, signed before a verified notary or an on-site city permit technician at St. Pete Municipal Building.

In a flood zone, everything gets counted
If your home is in a flood zone, the $7,500 exemption is off the table, and even exempt finish work gets counted: the city requires flood-zone projects to comply with its substantial improvement rules and to submit a cost breakdown for work that would otherwise be exempt. St. Pete limits remodeling in flood zones to 49% of the home's value, which the city refers to as FEMA's 49% rule.
Who pulls the permit, and how fast
A licensed contractor pulls it, or you do as an owner-builder on a home you own and live in. Since July 1, 2026, state law also gives the city 5 business days to approve or deny a complete application for plumbing, electrical, structural or mechanical permits on an existing single-family home when the work is under $15,000 and the city does the plan review.

Frequently asked questions
Clear, direct answers regarding St. Petersburg building codes and bathroom remodeling.
Replacing an existing toilet or sink in the same spot is on the city's exempt list as long as no valves or pipes have to be replaced or rearranged, and a new vanity cabinet or countertop counts as exempt finish work.
Only the parts that aren't plumbing, electrical, mechanical, gas or structural, and only if no part of the property is in a flood hazard area.
The same rules apply. Cabinets and countertops are exempt finish work, while moving the sink, adding circuits or relocating a gas range needs permits.
Florida's exemption for unlicensed work covers only casual, minor jobs under $2,500 in total, and it doesn't apply when the work is part of a larger project or split into smaller contracts.
