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 rulesCook County, GA
Zoning & raw-land occupancy
Varies locallyCook County has countywide zoning administered by its Building and Zoning office, but the incorporated cities of Sparks and Lenox each run their own separate zoning/land development codes that override the county inside city limits. source
Dwellings, tiny homes & RVs
Unclear - verifyNot confirmed whether Cook County has adopted Georgia DCA's optional Tiny House Appendix or has a specific RV-dwelling rule; ask the county Building and Zoning office directly.
Building permits & codes
Generally allowedCook County Building and Zoning issues permits and inspects construction, applying Georgia's state minimum standard codes as the floor. source
Septic & composting toilets
Generally allowedCook County Health Department (South Health District) requires a site evaluation before issuing a septic permit, following Georgia DPH's statewide onsite sewage rules; composting toilets aren't separately addressed and likely fall under the same rules. source
Greywater reuse
Generally allowedNo Cook County-specific greywater ordinance found; the county appears to defer to Georgia's state standard for simple, contained residential reuse. source
Rainwater harvesting
Generally allowedNo county-specific rainwater ordinance found; Cook County appears to follow the statewide plumbing code appendix allowing non-potable rainwater harvesting.
Private wells & water rights
Generally allowedCook County Health Department handles well siting via site evaluation, and Georgia's Water Well Standards Act (implemented by EPD) sets statewide standards for siting, construction, and driller licensing. source
Living disconnected from utilities
Unclear - verifyNo Cook County ordinance was found directly addressing full off-grid utility disconnection; a habitable dwelling still needs building permit inspection and an approved septic permit regardless of grid hookups.
