Alpharetta, Georgia Building Permits
Learn Alpharetta, Georgia building permit requirements, fees, timelines, zoning, code rules, wind/snow loads, inspections, and FAQs for local projects.
Wind
ASCE 7 basic wind speed: typically 115 mph ultimate design wind speed for Risk Category II buildings in Alpharetta/Fulton County. Higher risk categories or site-specific conditions may require different values.
Snow Load
Ground snow load: typically about 5 psf for the Alpharetta area, with roof live-load and snow-load design verified under the adopted Georgia code and ASCE 7.
Flood
Alpharetta uses FEMA Flood Insurance Rate Maps for floodplain administration. Properties near Big Creek, tributary streams, detention areas, and mapped special flood hazard areas may be in Zone AE or other FEMA-designated flood zones. Construction in or near a floodplain may require floodplain review, elevation certificates, lowest-floor elevation compliance, compensatory storage or no-rise documentation, and additional stormwater controls.
Earthquake
Seismic Design Category: typically SDC B for standard Risk Category II buildings on typical sites in the Alpharetta area, subject to confirmation by site class, soil conditions, occupancy, and ASCE 7 calculations.
Wildfire
Alpharetta is not generally subject to California-style wildland-urban interface building standards, but wooded lots, large residential parcels, and areas near undeveloped land can have localized wildfire exposure. Projects may be reviewed for fire apparatus access, hydrant spacing, driveway geometry, address visibility, defensible access, ignition-source separation, and compliance with the International Fire Code as adopted by Georgia and enforced locally.

Approval Timeline
Simple residential permits such as small decks, reroofs, trade permits, and minor interior work may be approved in about 1 to 5 business days if the submittal is complete. Residential additions, accessory structures, basement finishes with structural or MEP work, and new single-family homes commonly take about 5 to 15 business days for initial review. Commercial tenant improvements often require 10 to 20 business days for the first review, while new commercial buildings, shell buildings, restaurants, medical offices, assembly uses, or projects with site-development, fire, stormwater, or utility impacts may take 3 to 6 weeks or longer. Revisions, incomplete drawings, zoning issues, floodplain review, and Fire Marshal comments can extend the timeline.
Common Requirements
Typical Alpharetta permit submittals include a completed permit application, property address and parcel information, contractor licensing and business information, owner authorization if applicable, a current survey or site plan, construction drawings, structural details, floor plans, elevations, wall sections, framing plans, and energy-code compliance documentation. Site plans usually need to show property lines, setbacks, easements, driveways, sidewalks, existing and proposed structures, grading, drainage, tree impacts, and impervious surface. Commercial projects typically require Georgia-registered design professional drawings, code analysis, life-safety plans, accessibility details, occupancy classification, construction type, occupant load, egress plans, fire-rated assemblies, mechanical/electrical/plumbing drawings, and sprinkler or fire alarm plans when applicable. Separate trade permits are commonly required for electrical, mechanical, plumbing, gas, low-voltage, fire sprinkler, and fire alarm work.
Zoning Information
Alpharetta administers zoning through its Unified Development Code, which establishes residential, commercial, office, industrial, mixed-use, downtown, and overlay districts. Zoning review checks whether the proposed use is allowed and whether the project meets district standards for setbacks, height, density, lot coverage, parking, landscaping, buffers, signage, lighting, tree protection, and access. Properties in the Downtown Alpharetta area, mixed-use districts, stream buffers, floodplain areas, or special overlays may require additional review. Variances, conditional uses, rezonings, or design review may be needed before a building permit can be approved if the proposed work does not comply with the zoning district standards.
Permit Costs
Alpharetta permit fees are generally based on the city’s adopted fee schedule and may include a building permit fee, plan review fee, technology or administrative fees, trade permit fees, fire review fees, reinspection fees, and impact or utility-related fees for some projects. Small residential trade permits or minor repairs may be in the roughly $75 to $300 range. Decks, accessory structures, basement finishes, and residential additions often fall in the $150 to $1,000+ range depending on valuation and scope. New single-family homes commonly run from about $1,000 to $4,000+ when building, trade, plan review, and related fees are included. Commercial tenant improvements may range from several hundred dollars to several thousand dollars, while new commercial construction can be substantially higher. Applicants should confirm current fees with the City of Alpharetta fee schedule before budgeting.
Engineering Requirements
A Georgia-licensed professional engineer or architect is typically required for commercial construction, structural alterations, non-prescriptive framing, steel or concrete structural systems, major load-bearing wall removals, foundation repairs, retaining walls over typical code thresholds, elevated decks with unusual spans or loads, stormwater facilities, site walls, and projects using engineered design instead of prescriptive IRC provisions. Engineered roof and floor trusses must include truss design drawings. Commercial mechanical, electrical, plumbing, fire protection, and structural designs often require sealed drawings. Residential work that follows the prescriptive IRC may not need a full engineering stamp, but the city can require engineering when site conditions, spans, loads, slopes, floodplain constraints, or unusual construction details warrant it.
Local Code Adoption
Alpharetta enforces the Georgia State Minimum Standard Codes as adopted by the Georgia Department of Community Affairs, along with Georgia amendments and local ordinances. The commonly referenced statewide building codes include the 2018 International Building Code and 2018 International Residential Code with Georgia amendments, plus adopted plumbing, mechanical, fuel gas, electrical, energy, fire, accessibility, and existing-building codes. Applicants should verify the current code edition and amendments with Alpharetta before submitting because Georgia code adoptions and state amendments are updated periodically.
