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 rulesIndian River County, FL
Zoning & raw-land occupancy
RestrictedIndian River County has countywide zoning for its unincorporated area under Chapter 911 of the county code; structures must meet the minimum lot size for their zoning district, which varies by district. Incorporated towns in the county have their own separate codes. source
Dwellings, tiny homes & RVs
Unclear - verifyThe county requires site plan review for most structures except single-family dwellings, but I could not confirm an official county minimum dwelling size or a specific rule on RVs or tiny homes on wheels as permanent residences. Confirm with Community Development before relying on any third-party square-footage claims. source
Building permits & codes
RestrictedThe county's Community Development/Building Division issues permits under the Florida Building Code, and even sheds over 100 square feet must meet zoning district setbacks. source
Septic & composting toilets
Generally allowedOnsite sewage (septic) systems are permitted through the Florida Department of Health in Indian River County under state rules, with added nitrogen-reduction scrutiny for properties near the Indian River Lagoon. source
Greywater reuse
RestrictedNo county-specific greywater rule was found; the county appears to inherit Florida's statewide restriction, which generally limits reuse to toilet/urinal flushing. Not confirmed whether the county adds anything beyond the state rule.
Rainwater harvesting
Unclear - verifyNo official Indian River County or state page specifically regulates residential rainwater cisterns for non-potable use here. Not confirmed either way, so check with the county before building a system.
Private wells & water rights
Generally allowedWells under 6 inches in diameter are permitted through the Florida Department of Health in Indian River County under a delegation from the St. Johns River Water Management District; larger wells go through SJRWMD. The county also has designated groundwater delineated areas with added construction requirements. source
Living disconnected from utilities
Unclear - verifyNo official Indian River County source explicitly bans or allows full disconnection from utilities. You'd still need an approved septic system and, for potable well water, a DOH-issued well permit.
