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 rulesBotetourt County, VA
Zoning & raw-land occupancy
Varies locallyBotetourt County's zoning ordinance, administered by the county Planning Office, applies across unincorporated land; the Towns of Buchanan, Fincastle, and Troutville each administer their own separate zoning. source
Dwellings, tiny homes & RVs
RestrictedThe county ordinance excludes travel trailers/RVs from its definition of a dwelling and bars mobile homes built before 1976; mobile homes need a compliant foundation, underpinning, and anchoring. Tiny homes on permanent foundations likely count as conventional dwellings, but this isn't spelled out separately, so confirm with Building/Permitting. source
Building permits & codes
Generally allowedThe county's Community Development/Building/Permitting office requires permits for residential construction and inspects plumbing, electrical, mechanical, and structural systems before occupancy. Temporary power hookups during construction are allowed but limited to that purpose. source
Septic & composting toilets
Generally allowedSeptic systems are permitted under Virginia Department of Health rules, administered locally by the Roanoke City and Alleghany Health Districts; a state permit is generally required before the county issues a building permit. Composting toilets fall under the same state baseline, no separate county rule found. source
Greywater reuse
Generally allowedNo Botetourt-specific greywater ordinance was found; this appears to fall under the State Board of Health's general rules, administered locally by the health district. Not confirmed beyond that state baseline.
Rainwater harvesting
Generally allowedNo county-specific rainwater harvesting ordinance was found; small systems generally fall under Virginia's statewide VDH threshold rules, with larger or potable systems needing state review. Not confirmed as having any Botetourt-specific provision.
Private wells & water rights
Generally allowedPrivate wells are permitted through the Virginia Department of Health, with RCAHD staff or a licensed well driller/OSE handling siting and setbacks; well and septic applications can often be combined. Terrain-related siting challenges are mentioned in non-official sources, so treat that detail cautiously. source
Living disconnected from utilities
Unclear - verifyNo county ordinance explicitly mandates a grid electric connection, but the building permit/inspection process treats electrical systems as a standard part of occupancy sign-off, and temporary power hookups are limited to construction use. Whether a fully off-grid solar home can get a certificate of occupancy isn't confirmed, ask the Building/Permitting office directly. source
