Biloxi, Mississippi Building Permits
Biloxi, MS building permit guide covering costs, review times, zoning, inspections, floodplain rules, wind design, local codes, and submittals.
Wind
ASCE 7 basic wind speed: approximately 150 mph ultimate design wind speed for Risk Category II buildings in Biloxi and coastal Harrison County; confirm exact speed, exposure, enclosure classification, and risk category for the parcel.
Snow Load
Minimal snow load. Snow is generally not a controlling design condition in Biloxi, though roof live load and any adopted-code minimums still apply.
Flood
Biloxi has major FEMA coastal flood exposure, including AE, VE, Coastal A, shaded X, and low-lying drainage areas affected by storm surge, Back Bay, and Gulf-front conditions. Floodplain development permits, elevation certificates, elevated utilities, breakaway walls, flood openings, substantial improvement calculations, and construction above required flood elevations may be required.
Earthquake
Seismic risk is generally low. Ordinary Biloxi buildings are commonly designed in Seismic Design Category B, but final classification depends on ASCE 7 maps, risk category, soil site class, and project-specific calculations.
Wildfire
Biloxi’s primary natural hazards are hurricane wind, storm surge, and flooding rather than wildfire. Wildfire-specific construction requirements are generally limited, but fire code access, hydrants, address visibility, vegetation management, and separation from combustible materials remain important.

Approval Timeline
Simple residential repairs, reroofs, and trade permits may be issued in 1–5 business days if complete. Residential additions, new homes, and elevated coastal structures commonly take 1–3 weeks. Commercial tenant improvements often take 2–5 weeks, while new commercial buildings, restaurants, hotels, assembly spaces, waterfront projects, and floodplain projects may take 4–8 weeks or more depending on plan review comments and outside approvals.
Common Requirements
Biloxi permit applications commonly require a completed application, site plan or survey, building plans, floor plans, elevations, foundation plans, framing details, contractor license information, project valuation, and electrical, plumbing, mechanical, and gas scopes. Because Biloxi has significant coastal flood exposure, many projects also require flood zone determination, design flood elevation, elevation certificate, elevated mechanical/electrical equipment details, breakaway wall details where applicable, V-zone or Coastal A-zone construction details, and FEMA substantial improvement documentation. Commercial projects usually require sealed plans, code analysis, life-safety plans, fire protection details, accessibility compliance, parking and landscaping information, and certificate of occupancy documentation.
Zoning Information
Biloxi regulates land use through zoning districts for residential neighborhoods, commercial corridors, downtown, waterfront, industrial, gaming, hospitality, and special-purpose areas. Zoning review evaluates allowed use, setbacks, building height, parking, landscaping, signage, lot coverage, buffers, and overlay requirements. Historic, waterfront, casino, downtown, and redevelopment areas may involve additional review or design standards.
Permit Costs
Biloxi building permit fees are typically valuation-based and vary by project type. Minor residential and trade permits may be roughly $50–$250. Residential additions, accessory structures, and new single-family homes can range from several hundred dollars to $2,000 or more depending on valuation, floodplain review, and inspections. Commercial permits can range from several hundred dollars for a small tenant improvement to several thousand dollars for larger buildings, hotels, restaurants, or assembly projects. Separate fees may apply for plan review, electrical, plumbing, mechanical, gas, signs, reinspection, floodplain documentation, and certificates of occupancy.
Engineering Requirements
Mississippi-licensed design professionals are commonly required for commercial buildings, multi-family projects, structural alterations, elevated coastal construction, pile foundations, V-zone and Coastal A-zone work, flood-resistant design, retaining walls, canopies, signs, large roof openings, metal buildings, and non-prescriptive residential designs. Engineered wind-load calculations, uplift connections, shear walls, foundation details, and product approvals are often important on Biloxi coastal projects.
Local Code Adoption
Biloxi enforces locally adopted International Codes with local amendments, generally including the IBC, IRC, IPC, IMC, IFGC, IECC, Existing Building Code, and the National Electrical Code as adopted by the city. Recent practice has commonly aligned with modern ICC editions such as the 2018 I-Codes; verify the current adopted code set with the Building Division before submitting plans.
Typical Projects
Common Biloxi permit projects include elevated coastal homes, hurricane and storm-surge repairs, roof replacements, porches and decks, hotel and casino-related improvements, restaurant build-outs, retail tenant improvements, historic property renovations, waterfront development, accessory structures, signs, HVAC replacements, electrical service upgrades, and floodproofing or elevation work.
