Savannah, Georgia Building Permits
Savannah, Georgia building permit guide covering fees, timelines, zoning, historic review, flood rules, inspections, codes, and plan needs.
Wind
ASCE 7 basic wind speed: approximately 135-140 mph ultimate 3-second gust for Risk Category II buildings in the Savannah/Chatham County coastal area; exact speed varies by location, exposure, risk category, and ASCE 7 edition.
Snow Load
Ground snow load: minimal, typically 0 psf for coastal Georgia; minimum roof live loads and drainage design requirements still apply.
Flood
Savannah has extensive FEMA flood hazard areas due to tidal waterways, storm surge, the Savannah River, marshes, and low-lying coastal terrain. Projects in Zones AE, VE, and shaded X areas may require floodplain development approval, elevation certificates, design flood elevation compliance, flood openings, coastal foundation requirements, and substantial improvement/substantial damage review.
Earthquake
Seismic design is influenced by the Charleston/Southeastern seismic region. Many projects in the Savannah area may fall in Seismic Design Category C depending on site class and occupancy, with final category determined by ASCE 7 seismic parameters and geotechnical assumptions.
Wildfire
The urban core has relatively low wildfire exposure, but risk increases near wooded edges, islands, marsh/upland transition areas, and pine vegetation in the broader coastal region. Requirements typically focus on fire access roads, hydrants, defensible space, exterior fire spread limitations, and Georgia fire code compliance rather than a separate citywide WUI mandate.
Building Department
City of Savannah Development Services Department, Permits and Inspections / Building Safety; zoning and preservation review may involve the City of Savannah Planning and Urban Design Department and the Metropolitan Planning Commission depending on the project.
Approval Timeline
Simple residential trade permits may be issued within a few business days if complete. Residential remodels, additions, accessory structures, and new homes commonly take about 10-15 business days for plan review. Commercial tenant build-outs and new commercial buildings often take 3-6 weeks, depending on fire marshal review, life-safety complexity, utility coordination, civil/site plan approval, floodplain requirements, and historic review. Historic district certificates of appropriateness or major site-plan approvals can add several weeks or more.
Common Requirements
Typical Savannah permit submittals include a completed application, contractor licensing and business information, owner authorization, construction valuation, site plan or survey, floor plans, elevations, structural drawings, MEP drawings when applicable, energy code documentation, flood zone information, and product approvals for exterior components in high-wind areas. Commercial work generally requires a code summary, occupancy and construction type, occupant load, egress plans, accessibility compliance, fire-resistance details, fire protection drawings, and sometimes health department or alcohol-related approvals for restaurants and hospitality uses. Historic-area exterior changes may require photographs, materials descriptions, window and door details, and approval documentation.
Zoning Information
Savannah’s zoning system regulates land use, building form, setbacks, height, parking, signs, short-term vacation rentals, neighborhood compatibility, overlays, and historic preservation. The city includes downtown and neighborhood districts with special design and preservation standards. Building permit approval may require zoning verification, site plan approval, certificate of appropriateness for exterior work in historic districts, or floodplain development review in low-lying coastal areas.
Permit Costs
Savannah permit fees are typically based on project valuation, permit type, and required reviews. Small residential trade permits may be around $50-$200. Residential alterations, decks, porches, sheds, and additions may range from a few hundred dollars to $1,000+ depending on valuation and trade permits. New homes and larger renovations can reach several thousand dollars when building, plan review, trade, utility, and floodplain-related costs are included. Commercial tenant improvements often range from several hundred to several thousand dollars, while large hospitality, multifamily, or mixed-use projects can be significantly higher.
Engineering Requirements
Engineer or architect seals are frequently required for commercial work, multifamily buildings, structural alterations, elevated coastal/flood construction, foundation design, large openings, retaining walls, roof or floor load changes, pre-engineered metal buildings, fire protection systems, and designs outside prescriptive residential code provisions. Because Savannah is a hurricane-prone coastal community, structural attachments, roof systems, windows, doors, shutters, and elevated foundations may need wind and flood design documentation from a Georgia-licensed design professional.
Local Code Adoption
Savannah enforces the Georgia State Minimum Standard Codes adopted by the Georgia Department of Community Affairs, including the current statewide IBC and IRC code cycle with Georgia amendments, plus applicable electrical, plumbing, mechanical, fuel gas, energy, accessibility, floodplain, and fire code provisions. Local floodplain, zoning, and historic preservation standards can be more restrictive than the base building code.
Typical Projects
Common Savannah permit projects include historic home renovations, porch repairs, roof and window replacements, kitchen and bath remodels, elevated additions, short-term rental improvements, restaurant and hotel build-outs, multifamily renovations, downtown mixed-use tenant improvements, signs, flood repairs, and coastal wind-resistance upgrades.
