Do I need a permit in McDonough, GA?
McDonough sits in Henry County's Piedmont zone, where red clay soil, shallow frost depth, and Georgia's owner-builder exemptions create a permitting landscape different from Atlanta's stricter suburbs. The City of McDonough Building Department handles all residential permits — and they're generally straightforward to get if you know what triggers one. The key distinction: Georgia allows owner-builders to pull permits for their own residential work without a licensed contractor, which saves money and bureaucracy on smaller jobs. But "owner-built" doesn't mean "permit-exempt." A deck, shed, electrical upgrade, or roof replacement still needs a permit in McDonough — you just don't need to hire a contractor to file it. The 12-inch frost depth here means deck and shed footings are shallower than northern jurisdictions but still critical: frost heave in the red clay can crack foundations and shift structures fast. McDonough uses the 2022 International Building Code (IBC) with Georgia amendments, which aligns with most Georgia municipalities but differs in a few ways (pool barriers, setbacks, electrical rules). This page walks you through what needs a permit, what doesn't, how to file, what it costs, and what happens if you skip it.
What's specific to McDonough permits
Georgia's owner-builder exemption (Georgia Code § 43-41) is a big deal in McDonough. You can pull a residential permit for work on your primary residence without hiring a licensed contractor — as long as you're doing the work yourself and it's not a commercial building. You still need the permit; you just don't need a contractor's license. This applies to decks, sheds, electrical work, plumbing, HVAC, even additions. That said, some trades have carve-outs: electrical work over 50 amps usually requires a licensed electrician, and natural gas work always requires a licensed gas fitter. Verify with the McDonough Building Department before you start.
McDonough's Piedmont soil — mostly red clay with granite bedrock in the north — means frost heave and settling are real risks. The 12-inch frost depth is shallow compared to northern states, but it's not zero. Deck and shed footings must go below 12 inches to avoid heaving when the ground freezes (December through February). The red clay is also expansive: it swells when wet and shrinks when dry. Concrete slabs, foundations, and footings all feel this stress. The Building Department will ask about footing depth and method on deck/shed permits, and they inspect before you backfill. Don't skip this step — frost heave can crack a deck rim or push a shed off-kilter in one winter.
McDonough uses the 2022 IBC (updated from the 2018 edition most Georgia cities relied on for years). This matters for a few specifics: wind and seismic requirements are slightly stricter, electrical code references are more granular, and egress windows in basements have tighter sizing rules. If you're doing a basement renovation or adding bedrooms, the new egress-window math applies. The Building Department will cite the 2022 IBC if you file; it's worth checking their website or calling to confirm they've migrated fully. Some smaller jurisdictions lag on code updates — worth a 2-minute call.
The building permit portal and online filing status in McDonough are in flux. Henry County and the City of McDonough have been integrating permitting systems, but as of this writing, the City's online filing is limited. You can likely download forms and file in person or by mail, but check the City's website or call ahead to confirm current e-filing capability. In-person filing at City Hall is still the most reliable method — bring two copies of your site plan, a scaled drawing of the project, proof of property ownership, and a completed permit application. Over-the-counter permits (fences, sheds under a certain size) are usually processed same-day; plan reviews for additions or electrical work typically take 5–7 business days.
Common rejection reasons in McDonough: missing property-line dimensions on site plans (especially for fences and decks), no proof of ownership (deed, tax bill, or recent utility bill), setback violations that contradict the survey, undersized or improper footing details on deck/shed permits, and electrical plans without a single-line diagram for service upgrades. Show up prepared with a scaled site plan, a survey or county GIS printout showing your lot lines, and details on what you're building. If the application is incomplete, they'll tell you in-person or by phone — resubmit corrected copies within 30 days or restart the process.
Most common McDonough permit projects
The projects below are the ones McDonough residents file for most often. Each one has its own rules, fee structure, and timeline. Click any project to see the details specific to McDonough.
Decks
Attached and freestanding decks over 30 inches require a permit in McDonough. Footings must go below the 12-inch frost line; most inspectors want to see frost depth noted and footing detail sketches. Plan for 1-2 footing inspections and a final framing inspection.
Sheds and Detached Structures
Accessory structures (sheds, playhouses, detached garages) over 200 square feet need a permit. The 12-inch frost depth and expansive Piedmont clay mean proper footing depth is critical. Structures on piers or blocks often shift in McDonough's wet/dry clay cycles.
Fences
Most residential fences don't require a permit in McDonough if they're under 6 feet in rear/side yards, but corner-lot sight-triangle rules apply. Pool barriers always need a permit, even at 4 feet. Get a property-line survey or check the county GIS before you stake it out.
Electrical Work
Owner-builders can pull electrical permits in McDonough for most residential work (panel upgrades, circuits, outlets, lighting). Work over 50 amps or involving natural gas service typically requires a licensed electrician. Expect a permit plus 1–2 inspections (rough, final).
Roof replacement
Roof replacement or re-roofing (tear-off and new) requires a permit in McDonough. You can pull it yourself as the owner-builder; a roofing contractor can also file. The city will inspect after sheathing and before final shingles. Plan 5–7 days for review.
Additions and Room Conversions
Adding a bedroom, bathroom, or finished basement conversion requires a permit and plan review. Egress windows in basements must meet 2022 IBC sizing rules (minimum 5.7 sq ft, 20 inches minimum width). These typically take 7–14 days for plan review.

Georgia context for McDonough permits
Georgia's building code framework gives local jurisdictions some flexibility within state minimums. McDonough adopts the 2022 IBC and the Georgia Building Code, which includes amendments specific to Georgia's climate (wind zones, seismic minimums, high-humidity moisture control). The state has no residential building permit reciprocity — if you move a house plan from Florida or North Carolina to Georgia, it must be re-designed for Georgia's wind and seismic zones and McCormack soil data. Georgia also allows owner-builders broad latitude: you can pull your own residential permits without a contractor's license, as long as you're the property owner and the work is on your primary residence. This exemption doesn't apply to commercial buildings, manufactured housing, or properties you're building for resale. If you sell the property within a year of finishing the work, the Building Department may audit the permits and work — so keep all permit paperwork and inspection sign-offs. Finally, Georgia's Uniform Statewide Building Code (USBC) preempts most local zoning for building code matters, but local zoning (setbacks, lot coverage, height) still applies and often conflicts — get both the zoning ordinance and building code before you design.
Common questions
Do I need a permit for a small shed or detached structure in McDonough?
Yes, if the shed is over 200 square feet. Sheds 200 square feet or smaller and used only for storage of tools/equipment are often exempt. Playhouses, dog houses, and similar structures may have different thresholds — call the Building Department to confirm before you build. Footings are critical in McDonough's clay soil; even a small shed on blocks can heave if footings are too shallow.
Can I pull my own electrical permit in McDonough as the homeowner?
Yes, Georgia's owner-builder exemption lets you pull an electrical permit for your own home. However, work over 50 amps (service panel upgrades, large subpanels) or any natural gas work usually requires a licensed electrician. Single circuits, outlets, switches, and lighting fixtures are fair game. You'll need a single-line diagram for any panel work, and the city will inspect before the panel is covered. Budget 5–7 days for plan review plus 1–2 inspections.
What's the frost depth in McDonough and why does it matter?
McDonough's frost depth is 12 inches. Deck footings, shed piers, and foundation footings must go below 12 inches to avoid frost heave — the upward expansion of soil when water freezes. The Piedmont red clay here is especially prone to heaving because it's expansive. A shallow footing will shift or crack as the ground freezes and thaws from December through February. Always have footing depth called out on your permit drawings and pass inspection before you backfill.
Do I need a permit for a deck in McDonough?
Yes, if the deck is over 30 inches above grade or attached to the house. Raised decks, stairs, and railings all require a permit. You'll need a site plan showing setbacks from property lines, footing details (depth, diameter, spacing), framing details, and railing specs. Expect 1–2 footing inspections and a final framing inspection before you finish. Ground-level decks (patios) that don't require structural support or stairs typically don't need a permit.
What's the permit fee in McDonough?
Permit fees in McDonough are based on construction valuation, typically 1.5–2% of project cost. A $5,000 deck might run $75–$100; a $15,000 addition could be $225–$300. Some jurisdictions charge flat fees for simple permits (fences, small sheds). Call the Building Department to get current fee schedules — they vary and change year to year. Most jurisdictions accept cash, check, or credit card; confirm payment methods when you file.
What happens if I build without a permit in McDonough?
The Building Department can order a stop-work, issue a citation (fines typically $100–$500 per day of violation), and require you to apply for a retroactive permit. Unpermitted work doesn't pass final inspection, which means it won't transfer to a future buyer without disclosure. If you sell and the buyer discovers unpermitted work, the sale can stall while you retroactively permit or remove the structure. It's far cheaper and faster to get the permit upfront — most simple permits take 1–2 weeks.
Can I file my permit online in McDonough?
McDonough's online filing capability is limited as of now. You can likely download forms from the City website and submit by mail or email, but full e-filing with digital inspections is not yet available. In-person filing at City Hall is the fastest and most reliable method. Bring two copies of your site plan, scaled drawings, proof of ownership, and a completed application. Over-the-counter permits (simple fences, small sheds) are often approved same-day if complete.
Do I need a property survey for a permit in McDonough?
You don't always need a professional survey, but you need to prove your property lines. A county GIS map or tax parcel printout (free from the Henry County tax assessor) is often acceptable. For decks, sheds, and fences, the Building Department will want setback dimensions from the house or fence to property lines. If your survey is old or the lines are disputed, get a fresh survey — it costs $300–$800 but saves rework later. Corner lots always benefit from a professional survey because sight-triangle setbacks are strict.
How long does plan review take in McDonough?
Simple permits (fences, small sheds, straightforward electrical) often get over-the-counter approval same-day or next business day. Deck and roof permits typically take 3–5 business days. Additions, basements, and multi-trade projects (electrical + plumbing + framing) take 7–14 days. Complex projects or those missing information can take longer. Ask the Building Department for a specific timeline when you submit — they'll give you a stamped receipt with an expected approval date.
