Building Permits in St. Petersburg

St. Petersburg requires a building permit for most construction, alteration, and repair work affecting structural, electrical, plumbing, or mechanical systems. Permits are issued by the City of St. Petersburg Construction Services & Permitting Department (part of the Development Services Department), located at One 4th Street North, St. Petersburg, FL 33701. Phone: (727) 893-7231; ePlan Help Desk: (727) 893-7230.

All construction in St. Petersburg must comply with the Florida Building Code (FBC), 8th Edition (2023) — a mandatory statewide code administered by the Florida Building Commission under the Department of Business and Professional Regulation (DBPR). Because St. Petersburg sits on a peninsula between Tampa Bay and the Gulf of Mexico in Pinellas County, the city contains extensive coastal high hazard area (FEMA Flood Zones AE and VE), and the substantial improvement / 50% rule applies throughout the Special Flood Hazard Area. St. Petersburg is also in a Windborne Debris Region, requiring impact-rated or shutter-protected openings — but it is not in the High-Velocity Hurricane Zone (HVHZ), which is limited to Miami-Dade and Broward counties.

When You Need a Permit

You generally need a St. Petersburg building permit for:

• New construction, additions, and accessory structures (including ADUs and garage apartments)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, and mechanical (HVAC) changes, upgrades, or new installations
• Roofing replacement (full or partial) — always requires a permit in Florida; re-roofing in a Windborne Debris Region requires impact-rated or approved materials with Florida Product Approval numbers
• Window and door replacements — Windborne Debris Region opening protection requirements apply
• Swimming pools, spas, screen enclosures, docks, and seawalls
• Retaining walls above the applicable height threshold
• Solar photovoltaic systems and standby generators
• Demolition of any habitable or regulated structure
• Change of occupancy or use classification

Minor cosmetic work (interior painting, floor coverings, cabinetry without plumbing or electrical changes) is typically exempt. When in doubt, contact Construction Services & Permitting at (727) 893-7231 before starting work — unpermitted construction in a coastal community can result in stop-work orders, fines, insurance claim issues, and required demolition.

Florida Building Code and Coastal Requirements

Florida Building Code (FBC), 8th Edition (2023)

The FBC is the governing construction standard across all of Florida. Local amendments are limited and must be approved by the Florida Building Commission. The key FBC code packages applicable in St. Petersburg:

• FBC — Building (commercial structures)
• FBC — Residential (one- and two-family dwellings and townhouses)
• FBC — Energy Conservation (energy efficiency requirements)
• FBC — Existing Building (alterations and renovations to existing structures)
• FBC — Mechanical, Plumbing, Fuel Gas
• NFPA 70 / National Electrical Code (NEC) as adopted by Florida

Hurricane Wind Load and Windborne Debris Region

St. Petersburg is not in the HVHZ (limited to Miami-Dade and Broward counties only), but it is fully subject to Florida's high wind zone and Windborne Debris Region requirements under ASCE 7 as adopted by the FBC. This means:

• Structural plans must include wind load calculations prepared or reviewed by a Florida-licensed engineer or architect
• Roof-to-wall connections, sheathing, and fastening patterns must meet FBC wind design requirements for the applicable wind speed at your parcel
• Opening protection: windows, doors, skylights, and garage doors must be either impact-resistant or protected by approved shutters. Products must carry Florida Product Approval numbers (not Miami-Dade NOA, which is HVHZ-specific)
• Garage doors must be rated for the applicable wind zone
• Failure to specify Florida Product Approval numbers for exterior envelope products is a common plan review correction

Verify your parcel's design wind speed using the ASCE 7 wind speed maps adopted by the FBC or the Florida Building Commission's online tools.

Coastal High Hazard Area and FEMA Flood Zones

St. Petersburg's coastal geography places large portions of the city in FEMA Special Flood Hazard Areas (SFHAs), primarily Flood Zone AE (base flood elevations determined) and Flood Zone VE (coastal high hazard with wave action). Flood zone requirements add significant obligations to permitted work:

• First-floor elevation: New construction and substantially improved structures must have the lowest floor elevated to the Base Flood Elevation (BFE) plus any freeboard required by St. Petersburg's local floodplain ordinance
• V Zone construction: Structures in Coastal High Hazard Areas (Zone VE) must be elevated on pilings or columns; fill is generally prohibited; breakaway walls are required
• Flood openings: Enclosed areas below BFE in AE zones must have flood vents meeting FEMA / FBC specifications
• Check your parcel's flood zone at the FEMA Flood Map Service Center (msc.fema.gov) before designing any project

Substantial Improvement / 50% Rule

The substantial improvement rule is a critical consideration for any major renovation or repair of existing structures in St. Petersburg's flood zones. Under the National Flood Insurance Program (NFIP) and St. Petersburg's local floodplain ordinance:

• If the cost of improvements to a structure in a SFHA equals or exceeds 50% of the structure's pre-improvement market value (not assessed value), the entire structure must be brought into full compliance with current floodplain management standards
• This typically means elevating the lowest floor to current BFE requirements — which can require placing the structure on fill or piers and is often more expensive than the original improvement itself
• The 50% threshold is applied cumulatively over a rolling period defined in the local ordinance
• The rule applies both to voluntary improvements and to substantially damaged structures (e.g., from a hurricane or flood), where damage repair cost equals or exceeds 50% of pre-damage market value

Always confirm the applicable market value and cumulative improvement tracking with Construction Services & Permitting before finalizing your project scope and budget. For properties in Flood Zone VE, engage a licensed Florida engineer or architect familiar with coastal construction early in the design process.

Permit Costs

St. Petersburg building permit fees are set by the City's adopted fee schedule and are based on project valuation and scope. Typical cost components include:

• Building permit fee — calculated from project valuation (construction cost); scales with the scope of work
• Plan review fee — a percentage of the building permit fee, covering each required review discipline (building, structural, electrical, mechanical, plumbing, zoning, fire)
• Trade permit fees — separate fees for electrical, plumbing, and mechanical permits
• Impact fees — assessed for new construction or additions that add dwelling units or floor area; covers transportation, utilities, and parks
• State surcharge — Florida requires a per-permit surcharge that funds the Florida Building Commission
• Flood zone compliance fees — may apply for projects in SFHAs requiring floodplain review

Do not rely on third-party fee estimates. Always consult the current St. Petersburg Construction Services fee schedule, available through the AccessMyGov / eGovPLUS portal or by contacting Construction Services & Permitting at (727) 893-7231.

Typical Timeline

Review turnaround fluctuates with workload. Contact Construction Services & Permitting at (727) 893-7231 or check status in the AccessMyGov / eGovPLUS portal for current estimates.

The Process

1. Pre-submittal: Verify your zoning district on the St. Petersburg GIS Zoning Map and your flood zone on the FEMA Flood Map Service Center. Confirm applicable FBC wind speed and Windborne Debris Region requirements for your parcel. If your project is in a SFHA, assess the 50% rule exposure early.
2. Pre-application consultation: Recommended for complex projects, coastal/flood zone work, and substantial improvement scenarios. Contact Development Services at [email protected] or (727) 893-7471 for planning questions; contact Construction Services & Permitting at (727) 893-7231 for permitting questions.
3. Design and plans: Prepare construction documents. For structural, electrical, plumbing, and mechanical work, drawings must be signed and sealed by a Florida-licensed architect or engineer. Wind load calculations must be included for structural work; Florida Product Approval numbers must be specified for exterior envelope products in the Windborne Debris Region. Flood zone projects require elevation certificates and documentation.
4. Submit via AccessMyGov / eGovPLUS: Log in to your account and submit the application with all required documents and initial fees. Schedule an in-person appointment if needed at wb-stpete.qmatic.cloud.
5. Plan review: Construction Services & Permitting coordinates review across required disciplines — building, structural, electrical, mechanical, plumbing, zoning, fire, and floodplain as applicable.
6. Corrections: Respond to review comments in the portal and resubmit revised documents. Missing wind compliance documentation, absent Florida Product Approval numbers, and incomplete floodplain documentation are common first-cycle corrections.
7. Permit issuance: Pay any remaining fees. Post the permit card at the job site — it must be displayed and visible throughout construction.
8. Inspections: Schedule required inspections at each construction phase through the portal or by calling (727) 893-7231. Approved plans must be on-site and accessible for every inspection.
9. Final inspection and Certificate of Occupancy: Pass the final inspection. A Certificate of Occupancy (CO) or Certificate of Completion (CC) is required before occupying new or substantially altered structures.

Inspections

Typical inspection stages for a residential project in St. Petersburg:

• Foundation / footings (prior to pour; flood zone elevation verification for SFHA projects)
• Underground plumbing and electrical
• Slab pre-pour
• Framing and sheathing (including roof-to-wall connections for wind compliance)
• Rough plumbing, electrical, and mechanical
• Insulation (FBC Energy Conservation compliance)
• Drywall / wallboard
• Window and door installation (opening protection / Florida Product Approval verification)
• Flood zone compliance (elevation certificate / as-built survey for SFHA projects)
• Final building, plumbing, electrical, and mechanical

Schedule all inspections through the AccessMyGov / eGovPLUS portal or by calling Construction Services & Permitting at (727) 893-7231. The permitted plans must be on-site and accessible for every inspection.

Common Reasons for Corrections or Denial

• Plans do not comply with the Florida Building Code, 8th Edition (2023)
• Missing or incomplete wind load calculations or ASCE 7 documentation
• Plans not signed and sealed by a Florida-licensed architect or engineer where required
• Florida Product Approval numbers not specified for windows, doors, skylights, shutters, or roofing products in the Windborne Debris Region
• Flood zone non-compliance — insufficient first-floor elevation, missing flood vents, or V Zone construction standards not met
• Substantial improvement / 50% rule triggered but full floodplain compliance not addressed in plans
• Zoning conflicts under Chapter 16 (Land Development Regulations) — setbacks, height limits, lot coverage, or use not permitted in the applicable district
• Missing utility clearances (water, sewer, stormwater)
• Coastal or waterfront projects missing applicable regulatory approvals (e.g., SWFWMD, FDEP, Army Corps)
• Incomplete submittal — missing required plan sheets, product data, elevation certificates, or application attachments in the portal
