Harris County, Georgia generally requires a building permit before construction, moving, alteration or repair of a structure, with limited exceptions for certain accessory and agricultural structures1. Every property in Harris County has a zoning classification, so the parcel's district matters before you design or site a home2. A property using septic also needs a construction permit from the County Health Department before physical development begins3.

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 county 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. Do not read an exception from the building permit as an exception from zoning, septic approval, trade permits or another applicable rule; Community Development enforces the county's building codes and zoning regulations and performs plan review11. Georgia's mandatory construction codes apply statewide even where local enforcement choices differ12. An owner may build their own Georgia home without holding a state contractor license, but that licensing exemption does not waive Harris County permits, inspections, codes or zoning4.
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 work11. The office is at 125 Barnes Mill Road, Hamilton, GA 31811; call 706-628-4700 or email [email protected]11. Start there with the parcel number, proposed use, site plan and a plain description of every structure you intend to build. Harris County publishes department fee schedules, but the bundled fee source says its listed schedules took effect in 2018 and does not establish whether a later schedule superseded them, so ask Community Development for the current total before budgeting13. Georgia leaves permit administration and charges to local enforcement procedures rather than setting one uniform statewide fee14.
Does Harris County, Georgia have zoning?
Yes. Every property in Harris County is assigned a zoning classification that identifies how the property may be used2. The county's use tables distinguish uses that are allowed, allowed only after special-use approval, or prohibited, and dimensional standards vary by district7. Principal buildings must meet the street, side and rear setbacks shown for the applicable zoning district, while agricultural accessory buildings can have additional standards and exceptions6. That makes the parcel's zoning map designation the starting point for a house, cabin, manufactured home, tiny home, farm use or accessory building. Ask Community Development to confirm the classification and explain the applicable use and dimensional tables before ordering plans11. If a seller proposes dividing a larger tract, county subdivision rules can remain enforceable against the owner or developer creating the subdivision15.
How do septic permits work in Harris County?
For a Harris County lot that will use onsite sewage, obtain a construction permit from the County Health Department before beginning physical development or installing the system3. The permit follows a favorable site inspection and a finding that the site is suitable3. Harris County Health Department is at 210 Forest Hill Drive, Hamilton, Georgia 31811, and its published phone number is 706-628-503716. State rules require a final county health inspection and written approval before an onsite system is backfilled or used, including repairs, replacements and additions17. About 62.1% of county soils are rated without severe limitations for a conventional drain field, which still leaves a substantial share requiring closer site-specific evaluation18. 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 systems19.
Can you live in an RV or tiny home in Harris County?
We could not confirm a general Harris County rule allowing a recreational vehicle to serve as a residence on raw land, so ask Community Development about the parcel's zoning district, temporary-residence rules and required utilities before planning RV occupancy11. We also could not confirm a countywide minimum dwelling floor area; Community Development should confirm the applicable district and proposed dwelling type11. Georgia treats a site-built or modular tiny home as a dwelling subject to applicable building codes and local siting approval, and the optional tiny-house appendix applies only if locally adopted5. Harris County does not allow a dwelling to be occupied until required utility installations, including water supply and sanitary sewer systems, are completed to the satisfaction of the Health Department and Community Development Department20. Off-grid sanitation is therefore not a shortcut around county health review; Georgia recognizes only specified privies, approved alternative systems and properly certified composting toilets under the stated conditions21.
Building a home in Harris County: the steps, in order
- Ask Community Development to confirm the parcel's zoning classification, permitted use, setbacks and site-plan requirements116.
- Ask Harris County Health Department to evaluate septic suitability and issue the onsite sewage construction permit before physical development begins316.
- If the home will use a private well, ask the Health Department whether Harris County requires a well-construction permit; Georgia requires the contractor to contact county health for advance site review8.
- Secure driveway approval from Public Works for a county road, or a GDOT permit before work in a state-highway right-of-way910.
- Schedule required building inspections and obtain final written septic approval before backfilling or using the system2217.
- Confirm every required utility installation is accepted before occupying the dwelling20.
What should you check before buying land in Harris County?
Confirm zoning, setbacks, legal access, septic suitability, water source and flood exposure before closing. Harris County is heavily wooded, with about 87.7% forest cover, while about 81.6% of its land has slopes of 15% or less; those countywide figures do not replace a parcel survey, clearing estimate or site plan2324. Public Works issues county-road driveway permits, while work in a Georgia state-highway right-of-way requires a state permit910. Parcel-specific flood status and the complete local floodplain permit standard were not confirmed, so ask Community Development whether a floodplain review applies1125. Typical effective property tax is about 0.9%, and the median annual property tax bill is about $2,4702627. Qualifying agricultural or timber land may receive conservation-use assessment at 40% of current-use value through a 10-year covenant, but the owner must apply with the county tax assessors by the local deadline28.
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 Development111.
- Harris County's published fee claim is tied to schedules effective in 2018, so verify current charges with Community Development before budgeting1311.
- Do not occupy a Harris County dwelling until required water and sanitary-sewer installations are accepted by the Health Department and Community Development Department20.
- We could not confirm a general rule for RV residence, a countywide minimum dwelling size or a complete parcel-specific floodplain permit standard; ask Community Development before relying on any of those uses or assumptions11.
