Do I Need a Permit for a Bathroom Remodel in St. Petersburg, FL?
Bathroom remodel permits in St. Petersburg follow the Florida Building Code 8th Edition framework shared by Port St. Lucie: cosmetic work is permit-exempt, while plumbing, electrical, and structural changes require permits from Construction Services and Permitting. Notarized permit applications became required October 1, 2025. A Notice of Commencement must be recorded with the Pinellas County Clerk for projects over $2,500. Florida-licensed contractors perform all trade permit work. St. Petersburg's older housing stock — many homes from the 1920s through 1960s — creates specific renovation challenges including lead paint concerns and pre-plastic plumbing materials.

St. Petersburg bathroom remodel permit rules — the basics
Construction Services and Permitting administers bathroom remodel permits under the Florida Building Code 8th Edition. The permit framework is the same as Port St. Lucie: cosmetic work is permit-exempt; plumbing, electrical, and structural work each require separate permits from Florida-licensed contractors. DBPR-licensed plumbing contractors (CFC) and electrical contractors (EC) perform the respective trade work. Effective October 1, 2025, all St. Petersburg permit applications must be notarized. The Notice of Commencement must be recorded with the Pinellas County Clerk before work begins on projects over $2,500.
St. Petersburg's extensive older housing stock — the city has one of the highest concentrations of pre-WWII homes in Florida — creates renovation challenges that newer Florida cities like Port St. Lucie don't face. Homes built before 1978 may contain lead paint in the bathroom walls and trim; any permitted renovation that disturbs painted surfaces in a pre-1978 St. Pete home must comply with EPA's Renovation, Repair, and Painting (RRP) Rule, requiring RRP-certified contractors for the disturbing work. The Florida-licensed contractor managing the bathroom remodel should be RRP-certified or hire a certified subcontractor for demolition and surface preparation in older St. Pete homes.
Older St. Petersburg homes also frequently have galvanized steel supply pipes — the type that was standard before copper and CPVC became universal. Galvanized pipes corrode internally over decades, reducing water flow (a 1-inch diameter pipe can corrode to less than 1/4-inch effective diameter after 50 years) and discoloring water. A bathroom remodel in a pre-1960s St. Pete home that includes plumbing permits is an opportunity to address galvanized pipe in the bathroom supply lines — the Florida-licensed plumber replaces the galvanized section with modern PEX or copper as part of the permitted scope.
Duke Energy Florida (1-800-700-8744) is the primary electric utility for most St. Petersburg residential customers. Peoples Gas (1-877-832-6747) serves natural gas where available — relevant for any gas connection work in the bathroom (uncommon but applicable for radiant heating or gas water heaters). For standard bathroom electrical work within existing service capacity, Duke Energy coordination is typically not needed.
Scenario A
South St. Pete — 1950s home cosmetic refresh
A homeowner in south St. Petersburg has a 1957 CBS home with original bathroom tile and fixtures in a functional layout. The plan: new tile over existing stable tile substrate, like-for-like fixture replacements at same rough-in locations (WaterSense-certified 1.28 gpf toilet, 1.5 gpm faucet), new mirrors, repaint. RRP-certified contractor for any surface work on the 1957 home. No drains moving, no new circuits — cosmetic scope. No permits required. Permit: $0. Total: $10,000–$22,000.
Permit: $0 | RRP-certified contractor (pre-1978 home) | WaterSense fixtures | Total: $10,000–$22,000
Scenario B
Central St. Pete — 1940s home, full gut with galvanized pipe replacement
A central St. Pete homeowner guts a 1942 bathroom — original tile, galvanized supply pipes, no GFCI protection, original wiring. Scope: full gut, galvanized pipe replacement with PEX, new drain rough-in (slab cut on this CBS home), GFCI outlets, new exhaust fan circuit, updated layout. Permits: plumbing (CFC, slab work), electrical (EC, GFCI + exhaust fan). NOC recorded with Pinellas County Clerk. RRP-certified contractor for lead paint management. Notarized application. Total: $22,000–$45,000.
Plumbing + electrical permits + NOC | Notarized application | Galvanized pipe replacement | RRP-certified | Total: $22,000–$45,000
Scenario C
North St. Pete — tub-to-shower conversion, slab cut
A north St. Petersburg homeowner converts a combination tub/shower to a curbless walk-in shower with a new drain position. The Florida-licensed CFC plumber cuts the slab at the old and new drain positions, installs PVC rough-in, passes the rough-in inspection, and patches the slab. Florida-licensed EC installs GFCI outlet and exhaust fan circuit. NOC recorded. Notarized application submitted. Waterproofing membrane behind shower tile per FBC wet area requirements. Total: $20,000–$38,000.
Plumbing + electrical permits + NOC | Notarized | Slab cut | Waterproofing membrane | Total: $20,000–$38,000
| Variable | How It Affects Your Permit |
|---|---|
| Notarized Applications (Oct 1, 2025) | Effective October 1, 2025, St. Petersburg requires notarized permit applications. A significant procedural difference from most other guide cities. Confirm current requirements at (727) 893-7231. |
| NOC Required (Over $2,500) | Florida Statute 713 — NOC recorded with Pinellas County Clerk before work begins. Virtually all bathroom remodels exceed $2,500. Florida-licensed contractors file NOC as standard practice. |
| Older Housing Stock — Lead Paint (RRP) | Many St. Pete homes predate 1978. Permitted renovation disturbing painted surfaces in pre-1978 homes requires EPA RRP-certified contractors for the disturbing work. Confirm with your Florida-licensed contractor. |
| Galvanized Supply Pipes | Pre-1960s St. Pete homes often have galvanized steel supply pipes that corrode internally over decades. Bathroom remodel permits are an opportunity to replace galvanized pipe sections with PEX or copper as part of the plumbing permit scope. |
| Slab-on-Grade | Most St. Pete homes are slab-on-grade. Drain relocation requires CFC plumber to saw-cut slab. Rough-in inspection before patch; 3–5 day cure before tile. |
| WaterSense + Florida BC | Florida Building Code requires WaterSense-certified fixtures for all permitted plumbing replacements. 1.28 gpf toilets, 1.5 gpm faucets, 2.0 gpm showerheads. |

Common questions
What is the RRP Rule for St. Petersburg bathroom remodels?
The EPA's Renovation, Repair, and Painting (RRP) Rule requires that contractors disturbing painted surfaces in pre-1978 homes be certified under the RRP program. St. Petersburg's extensive pre-1978 housing stock means many bathroom remodel projects in older neighborhoods (South St. Pete, Historic Kenwood, Roser Park, etc.) require RRP-certified contractors for demolition and surface preparation. Ask your Florida-licensed general contractor about their RRP certification before contracting any bathroom remodel in a pre-1978 St. Pete home.
What are galvanized steel supply pipes and should I replace them?
Galvanized steel supply pipes were standard in American residential construction through the 1950s and into the 1960s. Over decades, the zinc coating corrodes from inside, forming iron oxide deposits that narrow the pipe's effective diameter and can discolor water. A bathroom remodel that includes plumbing permits is an excellent opportunity to replace galvanized supply pipes in the bathroom with modern PEX or copper — improving water pressure and quality. The Florida-licensed CFC plumber can include galvanized pipe replacement in the plumbing permit scope.
How does St. Petersburg compare to Port St. Lucie for bathroom permits?
Very similar frameworks — both apply the Florida Building Code 8th Edition, require Florida-licensed CFC plumbers and EC electricians, mandate NOC recording for projects over $2,500, and have slab-on-grade construction requiring slab cutting for drain relocations. Key differences: St. Petersburg requires notarized permit applications (effective October 1, 2025); St. Pete uses Pinellas County for NOC recording; St. Pete's older housing stock creates lead paint (RRP) and galvanized pipe considerations less common in Port St. Lucie's newer 1980s–2000s stock.
