Unincorporated Lamar County, Georgia requires building permits and construction inspections, with zoning approval limited to uses allowed in the parcel’s district1. Septic permits and inspections go through Lamar County Environmental Health, serving the county through District 4 Public Health2,3,4. Temporary camper or motor-home living at construction sites is allowed in A-R districts when the unit is at the rear of the property and a valid building permit is in place5.
Do you need a building permit in Lamar County, Georgia?
Yes.
Yes. Unincorporated Lamar County requires a permit before excavation or filling for construction, erecting, moving, extending or enlarging a building, making structural changes, installing a manufactured or industrialized building, or building or modifying electrical service6. New construction cannot receive electricity, water or sewage hookups until the building permit is secured6. Lamar County reviews the application and inspects the site before issuing a building permit, then explains inspection procedures and timing6. Georgia’s mandatory state building codes apply to construction in Lamar County whether or not locally enforced10. Construction must begin within 6 months after issuance, and work that stops must restart within 12 months or the permit becomes invalid6. Starting first can also cost more because the county may double the fee for unpermitted work6. Georgia's owner-builder exemption removes the state contractor-license requirement for an owner building the owner's own home, but it does not waive county permits, inspections, zoning or codes7.
Who is the Lamar County building department, and how do you reach it?
Lamar County Planning and Community Development is the first stop for a project in unincorporated Lamar County.
Lamar County Planning and Community Development is the first stop for a project in unincorporated Lamar County1. The office issues building permits, conducts construction inspections and administers zoning, planning, erosion and sedimentation control, floodplain management and code enforcement1. The office is at 790 Veterans Parkway in Barnesville and lists 770-358-5364 as its main number1. The county publishes building and zoning forms, a permit checklist, a utility-connection application and fee information1. The checklist calls for Health Department approval, a marked plat, deed, plans, and applicable trade or setup licenses; incomplete applications should not be submitted because applicable permits are issued together11. The published fee schedule is labeled FY2023, so confirm current charges before filing1.
Does Lamar County have zoning?
Yes.
Yes. Unincorporated Lamar County enforces zoning and issues permits only for uses allowed in the applicable district1. The county publishes a zoning map and reviews uses by zoning district8. Its residential labels specify homes larger than 2,000 square feet in R-1, 1,600 in R-2, 1,200 in R-3 and 800 in R-4, but confirm the parcel's current district because the published map was adopted in 20178. For land divisions, the minimum lot is generally 1 acre within 3 miles of Barnesville's geographic center and 2 miles of Milner's geographic center, with smaller lots possible on public sewer; outside those areas, the minimum is 5 acres12. Planning and Community Development should confirm current setbacks, height, lot coverage and permitted occupancy for the parcel1.
How do septic permits work in Lamar County?
Lamar County Environmental Health administers septic permits through District 4 Public Health under Georgia DPH rules.
Lamar County Environmental Health administers septic permits through District 4 Public Health under Georgia DPH rules2,3. New residential and commercial septic systems and repairs require permits and inspections; District 4 publishes the applications and directs applicants to the county Environmental Health office for local requirements and fees3,4. A system cannot be backfilled or used until the County Board of Health completes its final inspection and gives written approval13. The Lamar County Environmental Health Office lists (770) 358-148314. About 70.3% of Lamar County soils are rated without severe limits for a conventional drain field, but only a site evaluation answers whether a particular lot works15. Georgia generally requires a sewer connection when service is within 200 feet of the property line or in an abutting public right-of-way, with a stated exception for certain failing residential systems13.
Can you live in an RV or tiny home on land in Lamar County?
In unincorporated Lamar County’s A-R Agricultural-Residential district, a camper or motor home may serve as temporary living quarters at a construction site if placed at the rear of the property and backed by a valid building permit for the building under construction.
In unincorporated Lamar County’s A-R Agricultural-Residential district, a camper or motor home may serve as temporary living quarters at a construction site if placed at the rear of the property and backed by a valid building permit for the building under construction5. During a declared or county-determined emergency or disaster, the county may authorize temporary dwellings in any zoning district while the primary home is repaired; engineer-designed dwellings or parks and health and building/zoning approval are required16. Emergency permits last at most 6 months, with a discretionary additional 6-month hardship extension, and the temporary dwelling must be removed when approval expires16.
Ordinary long-term RV living and camping outside those conditions remain unconfirmed; ask Planning and Community Development about the intended use1. Site-built or modular tiny homes need applicable Georgia building-code compliance and local siting approval17. Lamar County’s published residential map labels homes larger than 800 to 2,000 square feet depending on district, so confirm the current minimum before choosing a tiny home1,8. Alternative sanitation must meet Georgia health standards; a composting toilet alone does not remove applicable septic review13.
