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, FL
Zoning & raw-land occupancy
RestrictedColumbia County has adopted countywide Land Development Regulations and a Comprehensive Plan administered by the county Zoning Department, with agricultural, residential, and commercial districts and lot/yard requirements. Fort White is a separate incorporated town with its own planning and permitting authority. source
Dwellings, tiny homes & RVs
RestrictedThe county Zoning Department publishes an RV Guide and a Special Family Lot Guide suggesting specific local limits, and mobile/manufactured homes must meet wind zone II or higher (generally excluding pre-1976 homes) with a special move-on permit process available. source
Building permits & codes
Generally allowedThe county Building Department reviews plans and issues permits for unincorporated areas under standard Florida timelines and expiration rules; Fort White issues its own permits within town limits, and projects near the Suwannee or Santa Fe Rivers need Suwannee River Water Management District floodway sign-off first. source
Septic & composting toilets
Generally allowedSeptic (OSTDS) permitting and inspection in Columbia County is still handled by the Florida Department of Health county office, since the county has not been transferred to DEP oversight; composting toilets are not separately addressed locally. source
Greywater reuse
RestrictedNo Columbia County ordinance on greywater was found, so the state Florida Building Code default (limited to toilet/urinal flushing with approved discharge) applies; confirm specifics with the county Building Department or health department.
Rainwater harvesting
Unclear - verifyNot confirmed at the county level; no Columbia County ordinance or health department guidance on residential rainwater cisterns was located, so the unsettled state baseline applies.
Private wells & water rights
Generally allowedWell construction and water use permitting in Columbia County goes through the Suwannee River Water Management District rather than the county; small domestic wells are typically exempt from the larger Water Use Permit requirement.
Living disconnected from utilities
Unclear - verifyNo Columbia County ordinance explicitly permits or bans full off-grid utility disconnection; any occupied dwelling still needs an approved septic system and must meet building code occupancy requirements enforced by the county Building Department.
