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 rulesMadison County, FL
Zoning & raw-land occupancy
RestrictedMadison County has a countywide Land Development Code, adopted under Florida growth management law, that applies to all unincorporated land and requires authorization before development. The City of Madison and other towns have their own separate zoning within their limits. source
Dwellings, tiny homes & RVs
Unclear - verifyNo official Madison County page specifies tiny-home minimum size or RV occupancy rules; the county Building Department does permit mobile/manufactured homes. Confirm specifics with that office.
Building permits & codes
Generally allowedThe Madison County Building Department enforces the Florida Building Code and issues permits for unincorporated areas; City of Madison residents permit through City Hall instead. source
Septic & composting toilets
Generally allowedMadison County is not among the counties transferred to state DEP oversight, so the Florida Department of Health in Madison County handles septic (OSTDS) permitting and inspection. source
Greywater reuse
RestrictedNo Madison County-specific greywater rule was found; the statewide Florida Building Code restriction is presumed to apply, so confirm with the county Building Department or Health Department.
Rainwater harvesting
Unclear - verifyNo official Madison County ordinance or agency page addresses rainwater harvesting specifically; not confirmed at the county level.
Private wells & water rights
Generally allowedWell construction and water use permitting in Madison County is handled by the Suwannee River Water Management District, not the county government. source
Living disconnected from utilities
Unclear - verifyNo explicit county ban on disconnecting from utilities was found, but any habitable structure still needs a county building permit and DOH-approved septic system regardless of grid status.
