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 rulesBuchanan County, VA
Zoning & raw-land occupancy
Unclear - verifyI couldn't find a standalone countywide zoning ordinance for Buchanan County, Virginia; the county's official code shows a Subdivision Ordinance and Building Construction chapter, and land-use control seems to run through platting and building permits rather than a zoning-district map. Confirm directly with the Buchanan County Planning Commission before assuming you can occupy raw land by right. source
Dwellings, tiny homes & RVs
Varies locallyThere's no Buchanan County-specific ordinance on tiny homes or RVs that I could find, so the state's Uniform Statewide Building Code baseline (with Appendix Q for tiny homes, and RVs generally not counted as dwellings) is what governs. I'd call the Buchanan County Building Code Office to check how they classify your specific structure. source
Building permits & codes
Generally allowedBuchanan County's Building Inspection Department enforces the state USBC and requires multi-stage inspections, but notably the county won't issue a building permit until you've got an updated septic layout and approved water source (or a statement from the PSA) from the Health Department. That's a real local hurdle for off-grid builders, so plan for it early and confirm specifics with the Building Code Office. source
Septic & composting toilets
Generally allowedI found no Buchanan County-specific composting toilet or septic ordinance; septic permitting is handled by the Virginia Department of Health under the statewide Sewage Handling and Disposal Regulations, and the county's building permit process requires that VDH sign-off before issuing a permit. source
Greywater reuse
Generally allowedNo Buchanan County-specific greywater rule turned up in my research, so this falls under the state's VDH-administered framework through the local health department. I'd still check with the health department for any local wrinkles.
Rainwater harvesting
Generally allowedI didn't find any Buchanan County ordinance addressing rain barrels or rainwater harvesting, so the applicable rules are Virginia's statewide VDH rainwater harvesting program, including its Tier 4 permit and registration process for non-potable use. source
Private wells & water rights
Generally allowedWell construction in Buchanan County is permitted through VDH under the statewide Private Well Regulations, and I found no separate county well ordinance. That said, the county's own building permit process requires proof of an approved water source (well or public system) from the Health Department before a permit is issued. source
Living disconnected from utilities
Unclear - verifyI didn't find any Buchanan County law that requires you to hook up to grid electricity, but the county's building permit practice effectively requires an approved water source and septic/PSA sewage connection before a permit is issued, which limits how 'off-grid' a permitted dwelling can really be. I'd call the Buchanan County Building Code Office directly to talk through your specific setup. source
