St. Petersburg Zoning & Local Regulations Overview

Understanding St. Petersburg Zoning (Chapter 16 LDRs)

St. Petersburg's zoning regulations are governed by Chapter 16 of the City Code—the Land Development Regulations (LDRs), established September 10, 2007, with updates every two years. The LDRs define permitted uses, dimensional standards, site design requirements, and development procedures for all land use categories within the city.

Key Zoning Considerations:

• Land Use Categories: Residential, commercial, industrial, mixed-use, and overlay districts

• Dimensional Standards: Lot sizes, setbacks, building heights, and parking requirements vary by zone

• Site Design Requirements: Landscape buffers, lighting standards, signage regulations, and architectural guidelines

• Permitted Uses: Vary by zoning district; some activities require variance or conditional use permits

• Overlay Districts: Additional requirements in coastal, historic, or specially designated areas

The City Planning Department & Zoning Division

St. Petersburg's City Planning Department and Zoning Division administer local land use regulations, review variance requests, and evaluate Conditional Use Permit (CUP) applications. The Zoning Division assesses whether proposed development aligns with comprehensive plan goals and LDR standards.

Typical Zoning Division Functions:

• Interpretation of zoning regulations and dimensional standards

• Review of preliminary plats and site plans for zoning compliance

• Evaluation of variances and conditional use permit requests

• Coordination with other city departments for unified development review

• Issuance of zoning clearance certificates upon compliance verification

Building Permits & Design Standards

Building Code Compliance & Permit Requirements

St. Petersburg adopts the Florida Building Code with municipal amendments, establishing minimum construction standards. Building permits are required for any construction, additions, remodeling, demolition, or work exceeding $500 or requiring inspection in Pinellas County.

Exempt from Building Permits:

• Small sheds under 100 square feet

• One-story detached structures under specific square footage

• Decks/patios under 12 inches high on residential property

• Interior remodeling not affecting structural systems

Standard Building Permit Process:

1. Determine Requirements: Identify what permits your project requires using the Pinellas County Permitting Guide

2. Prepare Application: Gather detailed drawings, site plans, energy compliance forms, stormwater requirements checklist, and project contact information

3. Submit Application: Submit through Pinellas County Access Portal with all required documentation

4. Plan Review: Building Department reviews compliance with applicable codes and regulations

5. Permit Issuance: Upon approval, receive permit and post at work site

6. Inspections & Compliance: Schedule required inspections; power cannot be activated until all inspections pass

Building permits remain valid for 6 months from issuance or last passed inspection, with extension opportunities upon written request.

Stormwater Compliance & Environmental Requirements

SWPPP Requirements for Construction Projects

Florida's Construction Generic Permit (CGP) administered by the FDEP requires Stormwater Pollution Prevention Plans (SWPPPs) for construction projects disturbing one or more acre. SWPPPs are site-specific documents outlining pollution prevention measures and best management practices (BMPs).

When SWPPP is Required:

• Projects disturbing one or more acre of total land area

• Projects part of larger common plan of development that will disturb one or more acre

• Projects discharging stormwater into surface waters of the state

• Projects discharging into Municipal Separate Storm Sewer Systems (MS4)

Key SWPPP Components:

• Site map with drainage patterns, slopes, soil disturbance areas, and BMPs location

• Erosion and sediment control measures (silt fences, turbidity curtains, sediment basins)

• Pollution prevention measures (material storage protocols, waste management)

• Stormwater management system design showing detention/treatment approaches

• Contractor/subcontractor responsibilities and certifications

• Inspection procedures and documentation (minimum weekly inspections, within 24 hours of storms ≥0.50 inches)

Environmental Resource Permits (ERP) & SWFWMD Requirements

St. Petersburg development affecting wetlands, surface waters, or altering stormwater flows requires Environmental Resource Permits from the Southwest Florida Water Management District. ERP applications require comprehensive engineering plans, hydrologic analysis, and water quality treatment calculations.

ERP Applications Include:

• Detailed site plans showing wetlands, surface waters, and proposed development

• Hydrologic modeling demonstrating stormwater impacts and management approach

• Water quality treatment calculations addressing nutrient and pollutant removal

• Erosion and sediment control measures during construction

• Long-term maintenance procedures for stormwater systems

• Wetland mitigation plans if impacts cannot be avoided

Coastal Construction Control Line (CCCL) Permitting

Understanding CCCL Regulations

Properties seaward of the Coastal Construction Control Line (CCCL) require Florida Department of Environmental Protection (FDEP) approval for construction activities. The CCCL identifies beaches and dunes subject to 100-year storm surge impacts, establishing FDEP's regulatory jurisdiction.

CCCL Key Considerations:

• Jurisdictional Determination: CCCL location must be identified on property survey; most St. Petersburg waterfront properties lie seaward

• Permitting Requirement: Construction, excavation, or modifications seaward of CCCL require FDEP approval

• Stringent Design Standards: Structures must withstand 100-year storm surge; design requirements typically restrict footprint expansion and require elevation above storm surge projections

• Existing Structure Limitations: Damaged structures may only be reconstructed to existing footprint; expansion prohibited

• Native Vegetation Protection: Marine turtle nesting areas and native salt-resistant vegetation must be protected

Floodplain Development & FEMA Requirements

Flood Zone Requirements & Base Flood Elevation Standards

Pinellas County enforces FEMA floodplain requirements for all new or substantially-improved structures in Special Flood Hazard Areas. New construction must be elevated at least one foot above Base Flood Elevation (BFE), with design floor elevations documented by registered professionals.

Floodplain Development Critical Steps:

1. Determine BFE: Contact Pinellas County Flood Information Services at (727) 464-7700 before developing plans

2. Calculate Elevation Certificate: Licensed surveyor must document finished floor elevation relative to BFE

3. Submit Floodplain Permit Application: Include Elevation Certificate, structural plans, cost breakdown, and substantial improvement disclosure

4. Comply with Design Standards: New construction above BFE; flood-proofing or other mitigation for elevated structures

5. Final Inspection: Building inspectors verify final elevation compliance before occupancy

Substantial Improvement Rule: If repair/improvement costs exceed 50% of structure value, entire structure must meet current floodplain requirements.
