Unincorporated Harris County, Georgia (not Harris County, Texas) generally requires a building permit before construction, issued through Harris County Community Development, with limited exceptions for certain accessory and agricultural structures12. County zoning applies throughout unincorporated Harris County, while incorporated municipalities may apply their own3. Septic permits come from the Harris County Health Department, and Community Development issues the certificate of occupancy45.

Do you need a building permit in Harris County, Georgia?
Yes, in most cases. Harris County requires a building permit before excavation or construction of a building or other structure and before most moving, alteration or repair work begins1. The ordinance has limited exceptions, including accessory structures of 400 square feet or less in the A-1, R-1 and R-2 districts, plus separate agricultural and small-accessory-structure exceptions1. The county's final inspection comes within 3 days after the owner notifies Community Development that the building is ready for occupancy17. A permit exception does not establish an exception from zoning, septic approval or another applicable rule. Georgia's mandatory construction codes apply statewide, and Harris County reviews plans and performs specified inspections, though the available rule does not give a complete inspection schedule for every project type1819. An owner may build their own Georgia home without a state contractor license, but that exemption does not waive county permits, inspections, codes or zoning8.
Who handles Harris County building permits and zoning?
Harris County Community Development is the building and zoning office: it reviews plans, issues building construction permits, enforces state building codes and local zoning, and administers zoning and variance work2. The office is at 125 Barnes Mill Road, Hamilton, GA 31811; call 706-628-4700 or email hcpermits@harriscountyga.gov2. Harris County publishes separate permit materials for new homes, accessory structures, accessory dwellings, manufactured housing, demolition, decks, remodeling, windows and residential pools20. Start with the form for the project type, then ask what plans and site information must accompany it because submission deadlines and review times were not confirmed202. A building or structure cannot be used until the county inspector or building official issues a certificate of occupancy after final inspection5. The published fee information dates to 2018, so request the current total before budgeting212.
Does Harris County, Georgia have zoning?
Yes. The Unified Development Code governs all land in unincorporated Harris County; incorporated municipalities may apply their own zoning6. The county publishes agricultural, residential, commercial, industrial and planned-development districts, and Community Development maintains the official zoning map22. District tables determine allowed and special uses, minimum lot area, setbacks, maximum lot coverage and building height2211101213. For principal buildings, the A-1 district table shows a 50-foot front setback, 20-foot side setback, 35-foot rear setback, 25% maximum lot coverage and a 35-foot height limit, and R-1 uses the same setbacks, so confirm the parcel's district before planning232425. A tiny house used as a dwelling is limited to the A-1 and R-R districts when it shares a lot with the primary structure; it must sit on a permanent load-bearing foundation and meet the residential code and Development Code26. Manufactured homes have separate placement, utility and inspection rules, and an RV cannot occupy a manufactured-home space27. Planned-development (CUPD) districts carry their own special regulations that override the general district rules, and the ordinance excerpt we reviewed does not state a numeric minimum floor area, so ask Community Development for the schedule that applies282. Dividing land also triggers county subdivision standards; a sequence creating four or more lots or building sites within the stated period is treated as a major subdivision29.
How do septic permits work in Harris County?
Harris County Environmental Health, a local office of the Georgia Department of Public Health, issues septic tank permits4. For a lot using septic, obtain a construction permit before physical development or installation; approval follows a favorable site inspection and suitability finding7. The office is at 210 Forest Hill Drive, Hamilton, Georgia 31811, and its published phone number is 706-628-503730. State rules require final inspection and written approval before an onsite system is backfilled or used, including repairs, replacements and additions31. About 62.1% of county soils are rated without severe limitations for a conventional drain field, so parcel-level soil evaluation still matters32. Septic-served lots also face county standards tied to soil, slope and pollution susceptibility11. If public or community sewer is available within 200 feet of the property line or in an abutting public right-of-way, Georgia generally requires connection, subject to the stated exception for certain failing residential systems33.
Can you live in an RV or tiny home in Harris County?
Harris County may permit an RV or camper as a temporary residence on the same lot as the primary permanent residence during construction or renovation, but a temporary building permit is required and the approval lasts no more than 90 days9. That provision does not answer general RV residence on raw land, so ask Community Development before relying on an RV for any other living arrangement92. A Harris County tiny house used as a dwelling is limited to 400 square feet of habitable floor area, excluding lofts, and is allowed on the primary-home lot only in the A-1 and R-R districts26. Required water and sanitary-sewer installations must be completed to the satisfaction of Health and Community Development before occupancy, but the rule does not require public utilities for every parcel34. Off-grid sanitation still requires an approved option and applicable health permits and inspections35.
Building a home in Harris County: the steps, in order
- Ask Community Development to confirm the parcel's zoning district, allowed use, lot size, setbacks, coverage, height and site-plan requirements2211101213.
- Ask Harris County Environmental Health to evaluate septic suitability and issue the construction permit before physical development begins47.
- If using a private well, ask Environmental Health whether a county permit is required; Georgia requires advance county-health site review14.
- Obtain a Public Works permit for access from a county road, or a GDOT permit before work in a state-highway right-of-way1516.
What should you check before buying land in Harris County?
Confirm zoning, dimensional limits, legal access, septic suitability, water source and flood exposure before closing. Harris County is about 87.7% wooded, while about 81.6% of its land has slopes of 15% or less; countywide figures do not replace a parcel survey, clearing estimate or site plan3637. A county-road driveway requires a Public Works permit and site inspection, while work in a Georgia state-highway right-of-way requires a state permit1516. A short-term vacation rental must meet county building and development codes, keep parking on the same lot, and follow the county's limits on rentable space, lighting and signs38. Development in an area of special flood hazard is tied to the county land-disturbance permit, which is approved only if the project meets the ordinance's flood hazard reduction provisions39. Parcel-specific flood status was not confirmed, so ask Community Development whether floodplain review applies to the parcel2. Typical effective property tax is about 0.9%, and the median annual bill is about $2,4704041.
Watch-outs
- A small accessory structure can fall within a building-permit exception and still remain subject to zoning, setbacks, septic, trade-permit or other rules; confirm the full project with Community Development12.
- Harris County's published fee information is tied to schedules effective in 2018, so verify current charges with Community Development before budgeting212.
- Do not use a Harris County building until the county issues its certificate of occupancy after final inspection5.
- The confirmed 90-day RV provision is limited to a temporary residence during construction or renovation on the primary-home lot; ask Community Development about any other RV occupancy92.
