Summary

Clayton County caps the maximum lot coverage for every zoning district, but the percentage is set individually for each district in the Article 3 layout (Sec. 6.4). Check your parcel's district standards with Community Development to find the coverage limit that applies to your lot.

These county ordinances apply to unincorporated areas of Clayton County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Lot Coverage: The maximum lot coverage shall be as noted in the Two-Page Layout for each Zoning District found in Article 3.

Full Breakdown

Lot coverage in unincorporated Clayton County is controlled through Sec. 6.4 (Lot/Yard Standards), which provides that the maximum lot coverage is set in the two-page layout for each zoning district in Article 3. Rather than a single countywide figure, the ceiling depends on the parcel's district, alongside the minimum lot area, lot width, frontage and yard setbacks that the same section assigns per district. Because those dimensional standards are published in each district's Article 3 layout, owners should confirm the exact coverage percentage and minimum lot size for their zoning before designing an addition or new structure. Georgia counties zone unincorporated land under O.C.G.A. Title 36, Chapter 66.

Violations & Fines

Exceeding the district's maximum lot coverage can cause permit or plan-review denial and, if built, code-enforcement action requiring removal of the excess structure or a variance from the Zoning Board of Appeals.

Frequently Asked Questions

How much of my lot can the building cover?
There is a cap, but the exact percentage is set for your zoning district in Article 3 under Sec. 6.4. Confirm your district's figure with Community Development.
Is there a countywide lot-coverage number?
No. Clayton County sets maximum lot coverage separately for each zoning district in the Article 3 layout rather than one blanket percentage.
