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 rulesHernando County, FL
Zoning & raw-land occupancy
Varies locallyUnincorporated Hernando County has countywide zoning under its Land Development Code (Appendix A), authorized by state law; Brooksville city limits are governed separately. No confirmed minimum acreage for occupying raw land was found. source
Dwellings, tiny homes & RVs
Unclear - verifyDistrict-specific building and setback rules exist in the county zoning code, but no standalone tiny-home ordinance or explicit minimum size was found; RVs as permanent dwellings appear restricted outside approved uses. Confirm specifics with county Planning and Zoning. source
Building permits & codes
Generally allowedThe Hernando County Building Division issues permits under the Florida Building Code with local amendments, and offers a Private Provider Program for alternate inspections. source
Septic & composting toilets
Generally allowedNew installations, repairs, and modifications require a permit from the Florida Department of Health in Hernando County, which continues local OSTDS permitting under the Clean Waterways Act framework. Composting toilets as a sole system are not addressed and should be confirmed directly. source
Greywater reuse
RestrictedNo Hernando-specific greywater ordinance was found; the county appears to rely on the state Florida Building Code and DOH OSTDS rules, which are fairly restrictive about greywater disposal. source
Rainwater harvesting
Unclear - verifyNo official Hernando County or SWFWMD page squarely addresses residential rainwater cisterns; this is not confirmed either way.
Private wells & water rights
Generally allowedHernando County is not on the state's delegated list for county health department well permitting, so the Southwest Florida Water Management District (SWFWMD) issues Well Construction Permits here. source
Living disconnected from utilities
Unclear - verifyNo county ordinance explicitly bans full grid disconnection, but occupying a dwelling practically requires an approved well and septic system to obtain a certificate of occupancy through the county Building Division. source
