Building Permit Requirements in Georgia

Most Georgia cities require a building permit for decks that are more than 30 inches above finished grade or exceed 200 square feet. These thresholds follow the IRC standards adopted into the Georgia residential code. Smaller ground-level decks are often exempt, though setback and zoning rules still apply. Decks attached to the house via a ledger board typically require a permit regardless of size because the connection creates a structural dependency on the primary dwelling.

Atlanta processes deck permits through its Office of Buildings and requires a site plan, structural drawings, and details about the foundation and ledger board connection. The city's permitting process has moved increasingly online, and straightforward residential deck applications can be submitted and tracked digitally. Athens requires deck permits for structures exceeding the standard thresholds and applies additional review requirements in its historic preservation districts, where exterior modifications including decks may need approval from the Historic Preservation Commission if the deck is visible from a public right-of-way.

Permit fees vary by city but generally range from $75 to $350 depending on project size and the local fee calculation method. Some Georgia cities base fees on estimated construction cost, while others use flat fee schedules. Review times in the Atlanta metro area typically run 7 to 15 business days, though times can be shorter in smaller cities with lower permit volumes. Georgia's relatively mild frost line, typically 12 to 18 inches, means deck footings don't need to go as deep as in northern states, which reduces foundation costs.

Fence permit requirements in Georgia depend on the city, fence height, and location on the property. Most cities allow fences up to 6 feet in rear and side yards without a building permit. Front yard fences are typically limited to 4 feet, and exceeding these heights triggers a permit or variance requirement. Some cities require a zoning permit or compliance check for any new fence to verify that it meets setback and visibility standards.

Savannah is notable for its historic district regulations, which impose strict controls on fence materials, design, and placement within the Savannah Historic District and its surrounding landmark neighborhoods. A standard wood privacy fence that would be routine in a suburban subdivision may require detailed review and approval from the Historic District Board of Review in downtown Savannah. Materials, height, style, and even color are subject to scrutiny. Columbus follows more standard rules, with permits required mainly for fences exceeding height limits or located on corner lots.

Georgia's warm climate means many homeowners install fences around pools, and state law requires pool enclosures to meet specific barrier standards under the mandatory swimming pool code. If your fence serves as a pool barrier, it must meet requirements for minimum height, self-closing and self-latching gates, and maximum spacing between pickets, regardless of what your local fence ordinance otherwise allows. Call 811 before digging fence post holes to have underground utilities marked.

Small storage sheds are commonly exempt from building permits in Georgia. Most cities exempt sheds that are 120 to 200 square feet or smaller, single-story, and used strictly for storage without electrical or plumbing connections. The exact threshold varies by jurisdiction because local zoning ordinances set their own limits within the framework of the state code.

Atlanta generally exempts accessory structures under 200 square feet that are single-story and don't include utilities. However, the city still requires that exempt sheds meet setback requirements, not exceed lot coverage limits, and comply with neighborhood overlay requirements where they exist. A shed that meets the building code exemption could still need a zoning review in some Atlanta neighborhoods. Augusta follows a similar approach with exemptions for small storage buildings, and the city's online permitting system can help homeowners quickly determine whether their specific shed project needs a permit.

If your shed requires a permit, plan to submit a site plan showing the structure's location relative to property lines and existing buildings. Setback requirements apply even to exempt sheds in most jurisdictions, with typical minimums of 3 to 5 feet from side and rear property lines. Georgia's clay soils and seasonal rainfall patterns make proper site drainage important for shed placement. Poor drainage around a shed foundation can lead to water intrusion and structural settling over time, so grading the area to direct water away from the structure is a worthwhile step even when no permit is involved. Permit fees for sheds requiring a permit are generally under $150.

A ground-level patio made of concrete, pavers, or natural stone typically does not need a building permit in most Georgia cities. Patios trigger permit requirements when they include a permanent roof or cover structure, are elevated above grade, or include electrical or plumbing work such as outdoor kitchens, gas fire pits, or built-in lighting. Any covered patio attached to the house is treated as a structural addition and goes through full plan review.

Atlanta requires permits for covered patios and applies impervious surface limits that can be a significant factor on smaller infill lots in the city's older neighborhoods. Atlanta's tree ordinance can also come into play for patio projects if construction requires removing protected trees, which triggers a separate review and possible mitigation requirement. Savannah similarly requires permits for covered outdoor structures and applies additional design standards in its historic districts, where the appearance of a covered patio visible from the street may need Historic District Board of Review approval.

Georgia's long outdoor season, running eight to ten months in most of the state, makes patios with covered areas especially popular. Many homeowners combine a patio with a screened porch or outdoor kitchen that includes a gas grill, sink, or fireplace. These combination projects require a building permit and should be submitted as a single application covering all elements. If gas or electrical work is involved, separate trade permits may also be needed. Permit fees for covered patios typically range from $100 to $300, with review times of 7 to 15 business days in most jurisdictions.

Building a garage in Georgia requires a building permit in virtually every jurisdiction, whether the garage is attached or detached. Garages are substantial structures that involve foundations, structural framing, roofing, and typically electrical work. They exceed the size and complexity thresholds that exempt smaller accessory buildings, and the project goes through plan review for structural adequacy, fire separation (for attached garages), zoning compliance, and electrical safety.

Atlanta requires full plan review for garage construction, including structural, electrical, and site plans. The city reviews garage projects for compliance with its zoning ordinance, which regulates setbacks, height, and lot coverage for accessory structures. In certain neighborhoods, design overlay requirements may also govern the exterior appearance of a garage. Columbus requires similar documentation and applies its own setback and impervious surface standards, with particular attention to garages on lots where stormwater drainage is a concern.

Permit fees for garages in Georgia typically range from $200 to $600 depending on the city and the project's size and estimated cost. Some cities calculate fees based on square footage, while others use a percentage of estimated construction value. If your property is in a flood zone, the garage may need to meet additional construction standards, including requirements for flood-resistant materials below the base flood elevation and flood vents to equalize water pressure. Inspections at the foundation, framing, electrical rough-in, and final stages are standard.
