Read this before you act on anything below. This is my researched starting point for Columbia County, GA, not legal advice and not a guarantee. 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 rulesColumbia County, GA

Zoning & raw-land occupancy

Varies locallyColumbia County does have countywide zoning for unincorporated areas, unlike some GA counties, under Chapter 90 of the Columbia County Code. What you can do with raw land depends heavily on the zoning district, so I'd call the Planning Department for a zoning verification letter on any specific parcel before buying. source

Dwellings, tiny homes & RVs

Unclear - verifyI couldn't confirm on the county's own site whether Columbia County has adopted Georgia's optional Tiny House Appendix or what its policy is on RVs as permanent residences. This is one to confirm directly with the county Planning & Zoning and Building Inspections offices before you plan anything.

Building permits & codes

RestrictedBuilding permits are required and handled by Columbia County's Inspections & Reviews office, which follows Georgia's state minimum standard codes and coordinates with the Health Department on sewage/water questions for any project. source

Septic & composting toilets

Generally allowedSeptic systems are permitted through the East Central Health District's Environmental Health program, following Georgia's statewide onsite sewage rules (Chapter 511-3-1). Composting toilets aren't addressed on the county's page, so treat stand-alone composting toilet approval as not confirmed and check with Environmental Health directly. source

Greywater reuse

Generally allowedNo Columbia County-specific ordinance was found modifying the state greywater law, so the state baseline applies, with the East Central Health District overseeing any engineered greywater systems tied to onsite sewage rules.

Rainwater harvesting

Generally allowedI found no Columbia County-specific restriction on rainwater harvesting, so the state plumbing code's allowance for non-potable rainwater use appears to apply, but this isn't confirmed at the county level.

Private wells & water rights

Generally allowedPrivate wells are permitted with site evaluation and permitting through Environmental Health under the East Central Health District, with Georgia DPH's Non-Public Well Program providing statewide technical backup. If you're on well water, expect state and local water testing requirements too. source

Living disconnected from utilities

Unclear - verifyThere's no dedicated Columbia County ordinance addressing full grid disconnection directly. In practice it's governed indirectly through building, septic, and well permitting, since any home still has to pass Environmental Health and Inspections review for its water and wastewater method no matter how it's powered.
