Coweta County Inland wind zone

Barndominium Builders in Coweta County, GA

Coweta is an I-85 exurb with a large rural remainder. Newnan and Senoia together hold about a third of the county's people on under six percent of its land, so for nearly every buildable acre the authority is Coweta County Community Development, and its rural district sets a 5-acre minimum lot and a 1,725 square foot minimum house. The county contracts plan review and inspections to SAFEbuilt, whose homeowner guides are published against the 2024 IRC.

The expensive surprises are in the ground, not the building

Most of Coweta County rates poorly for dwellings in the soil survey, and the reason is water sitting close to the surface rather than weak ground. That makes the pad elevation and the drainage plan the two line items most likely to move your budget. We price the dirt before we price the building.

What we build in Coweta County

All nine services are available across Coweta County. The three below are where a project on a Coweta County parcel usually starts — the permit, the drawings, and the build itself. What a build costs depends far more on the parcel than on square footage, so we price against your land rather than publishing a rate card.

Permitting & Engineering

Sealed structural engineering and the permit that depends on it, from submittal through final inspection.

Custom Plans

Barndominium floor plans drawn to your land, your family, and the 2024 Georgia residential code.

Building in Coweta County: common questions

6 questions we get asked most often about building in Coweta County. If yours is not on the list, ask it directly.

Start your project
Does Coweta County actually inspect a barndominium, or does it count as an agricultural building?
It inspects. Coweta County Community Development issues the permit and SAFEbuilt carries out the plan review and the field inspections under contract to the county, against the 2024 IRC with Georgia Amendments. The agricultural exemption in Georgia law does not reach a barndominium: it is written for a structure that is not used for residential purposes, so the moment the building is lived in it is a dwelling and it is inspected as one. That is a good thing here. In Coweta the inspection is going to happen either way, and a building that was engineered and permitted properly is the one that passes, appraises and insures.
How big does my lot have to be in Coweta County?
In the RC Rural Conservation district, which covers most of the unincorporated county, the minimum is five acres for a single-family dwelling. Two qualifications matter more than the headline number. First, 1.3 of those acres have to be a contiguous building site measured outside the 100-year floodplain, wetlands, impoundments, detention ponds and utility easements. Second, the ordinance says outright that the minimum lot size is increased as far as necessary to encompass a site for a conventional on-site septic system, so on difficult soil the real minimum is larger than five acres. There is also a homestead-lot route at 1.6 acres with public water or 2 acres without, but it is limited to a family member of the first, second or third degree.
Is there a minimum house size in Coweta County?
Yes, and it catches people out. Coweta's dimensional table sets a minimum floor area of 1,725 square feet per dwelling, and it applies to the RC district and to every rural residential development type in the county — the homestead lots and all four estate-lot and conservation-subdivision types carry the same figure. That is roughly a 40 by 44 conditioned footprint before any shop or garage space is counted. If you were planning a compact shell as the entire residence, the plan has to grow before it can be permitted in unincorporated Coweta.
My parcel will be on septic. What has to happen, and in what order?
Septic comes before the building permit, not alongside it. Coweta's zoning ordinance will not approve a lot for building until the Community Development Department is shown proof that it contains a site adequate to support a conventional on-site septic system as Georgia law defines that term. The county's own construction guide then says that if you are on a septic tank you must have approval from the county health department before the permit is issued. So the sequence is soil evaluation and health department approval, then site preparation permit, then the building permit. We confirm the septic site with the county before a slab is designed, because the location of the drain field usually decides where the building sits.
Coweta bans framing wider than 16 inches on centre. Does that rule out a post-frame or steel barndominium?
No, it points straight at how these buildings have to be designed anyway. Coweta's own code addendum prohibits framing spaced wider than 16 inches on centre, interior walls included, but it carves out engineered factory-built trusses and, more importantly, any structure whose plans and specifications bear the seal of a registered professional engineer. A clear-span rigid frame or a post-frame building does not fit any prescriptive framing standard in the residential code to begin with, so it is engineered regardless. In Coweta that engineer's seal is also what satisfies the local spacing rule.
What does the permit cost, and how long is it good for?
Coweta calculates the building permit fee from the International Code Council Building Valuation Data at $4.00 per $1,000 of calculated construction cost, based on the construction type and occupancy group rather than on your contract price, and the county states that the fee covers plan review as well as the inspections. Budget separately for the site preparation permit, which is required before any grading of a residential lot. Once issued, the permit expires if work has not commenced within six months, or if work is suspended or abandoned for six months, with extensions of up to twelve months available in writing for justifiable cause.

Building in Coweta County?

Start with the plan. Tell us what you want to build and we will draw it, then confirm what Coweta County will actually let you put on the parcel and what wind load it has to meet. That conversation costs nothing.
