Read this before you act on anything below. This is my researched starting point for Collier County, FL, 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 rulesCollier County, FL

Zoning & raw-land occupancy
Varies locallyCollier County's Land Development Code (adopted via county Ordinance 04-41) governs land use countywide; Rural Agricultural and Estates districts allow single-family homes by right but minimum lot sizes and density vary by district under the Growth Management Plan. source
Dwellings, tiny homes & RVs
RestrictedCollier County Code Enforcement restricts RV parking/occupancy on residential lots to specific locations, with Estates and Agricultural zoning exempted from those restrictions; a temporary agricultural mobile-home exception exists, but full-time RV living outside parks isn't confirmed as permitted. source
Building permits & codes
RestrictedFlorida Building Code is enforced locally by Collier County's Building Plan Review and Inspection Division; permits, inspections, and a Certificate of Occupancy are required with no exemption for off-grid construction. source
Septic & composting toilets
Generally allowedThe Florida Department of Health in Collier County (Environmental Health) permits and inspects onsite sewage treatment and disposal systems; installation is done by licensed private contractors. source
Greywater reuse
RestrictedNo Collier County-specific greywater ordinance was found; the state Florida Building Code standard applies, generally limiting reuse to toilet/urinal flushing with DOH/DEP-approved connections. source
Rainwater harvesting
Unclear - verifyNo official Collier County or Florida DOH/DEP page specifically addresses residential rainwater cisterns; not confirmed, so ask the county or state directly.
Private wells & water rights
Generally allowedSouth Florida Water Management District has delegated well construction permitting to Collier County itself, which issues permits for new wells and requires licensed well contractors; a single-family domestic well generally doesn't need a separate consumptive use permit. source
Living disconnected from utilities
Unclear - verifyNo Collier County ordinance explicitly bans full utility disconnection, but any occupied dwelling still needs a permitted septic system, a permitted well, and a building permit/Certificate of Occupancy, so off-grid living is achieved through individual permits rather than a blanket exemption.
