The local rulesBrevard County, FL
Zoning & raw-land occupancy
Varies locallyBrevard County has countywide zoning under Chapter 62 of its Code of Ordinances, administered by the Planning & Development office; density and lot minimums vary sharply by classification (agricultural, conservation, residential). source
Dwellings, tiny homes & RVs
RestrictedCounty code sets minimum floor areas for site-built homes by zoning district, and RVs cannot be used as permanent residences (occupancy capped at a limited number of consecutive days), per Brevard County Code. source
Building permits & codes
Generally allowedThe Brevard County Building Department enforces the Florida Building Code and issues the permits and inspections required for construction, including sign-off tied to septic documentation. source
Septic & composting toilets
RestrictedDOH-Brevard, delegated by the state DEP, permits septic systems, but Brevard County has its own 2018 ordinance requiring advanced nitrogen-reducing systems on the barrier islands, Merritt Island, and mainland areas near the Indian River Lagoon, a stricter local layer on top of the state baseline. source
Greywater reuse
Unclear - verifyNo Brevard-specific greywater ordinance was found; it appears to inherit the general state standard limiting reuse to toilet/urinal flushing. Confirm with the county Natural Resources office if you're planning a system. source
Rainwater harvesting
Unclear - verifyNo official Brevard County page specifically addresses household rainwater catchment for use; the county's stormwater program covers runoff and drainage, not household catchment. Not confirmed either way locally. source
Private wells & water rights
Generally allowedDOH-Brevard is the delegated permitting authority for most wells under six inches in diameter; wells six inches or larger, and wells in state-designated 'delineated areas' (Brevard is one), go through the St. Johns River Water Management District instead. source
Living disconnected from utilities
Varies locallyNo explicit county ban on disconnecting from utilities was found, but a certificate of occupancy still functionally requires an approved septic/sewer connection and approved water supply, per Building Department and DOH-Brevard processes. source
