Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesClayton County, GA
Zoning & raw-land occupancy
Varies locallyClayton County has countywide zoning for unincorporated areas, administered by the county's Planning & Zoning office and currently under a rewrite; but most residential land sits inside one of six cities, each with its own separate zoning code. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Clayton County-specific rule on tiny homes or RVs as permanent dwellings was confirmed; it falls under the unincorporated zoning appendix or, inside a city, that city's code. Ask county Planning & Zoning directly. source
Building permits & codes
Generally allowedThe county's Building Permits section issues building, mechanical, electrical, and plumbing permits for unincorporated Clayton County, with Georgia's state minimum codes as the floor; cities issue their own permits inside city limits. source
Septic & composting toilets
Generally allowedThe Clayton County Board of Health's Office of Environmental Services administers septic/on-site sewage permits and inspections, applying the state's Chapter 511-3-1 standards. source
Greywater reuse
Generally allowedNo county-specific greywater rule was found; this appears to simply inherit Georgia's state greywater statute (O.C.G.A. §31-3-5.2) with no confirmed local addition.
Rainwater harvesting
Generally allowedNo county-specific rainwater rule was found; this appears to inherit the statewide plumbing-code appendix allowing rainwater harvesting, with no confirmed local restriction.
Private wells & water rights
Varies locallyPrivate wells are legal under Georgia's state Water Well Standards Act, but Clayton County Water Authority's near-universal service area and its role in permit coordination for nearby cities suggest practical hurdles; no dedicated county well ordinance was confirmed. source
Living disconnected from utilities
Unclear - verifyNo county ordinance mandating water/sewer hookup was confirmed, but CCWA's extensive coverage across the county and its six cities means full off-grid utility disconnection is not clearly settled and should be discussed with zoning and building officials. source
