Read this before you act on anything below. This is my researched starting point for Alleghany County, VA, not legal advice and not a guarantee. 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 rulesAlleghany County, VA

Zoning & raw-land occupancy
RestrictedAlleghany County has countywide zoning with seven districts (AR, R-1, R-2, B-1, B-2, M-1, PUD), each with its own setbacks and allowed uses; any new construction needs zoning approval from the county's Zoning and Planning division. Incorporated towns like Iron Gate administer their own separate zoning approval on top of the county's. source
Dwellings, tiny homes & RVs
Unclear - verifyFoundation-built small homes appear to fit within existing residential zoning, but no official county page confirms rules for tiny houses on wheels or long-term RV occupancy. Not confirmed, call the county Zoning Department directly. source
Building permits & codes
Generally allowedAlleghany County enforces the Virginia Uniform Statewide Building Code, Volume I, a state-level code administered locally by the county Building Inspections Department. A narrow exemption covers low-voltage wiring and small detached accessory structures under a set square footage, but zoning approval is still required. source
Septic & composting toilets
Generally allowedSeptic systems are permitted through the Alleghany Health District (Virginia Department of Health), using the state application process with a licensed soil evaluator. Composting toilets aren't separately addressed on official county pages, so the standard state review likely still applies pending confirmation. source
Greywater reuse
Unclear - verifyNo Alleghany County or Alleghany Health District page specifically addresses greywater reuse; this falls back to Virginia's statewide greywater regulation administered through the local health district. source
Rainwater harvesting
Unclear - verifyNo county-specific rainwater harvesting rule was found; Virginia's general state rules on rain barrels and larger catchment systems apply by default, with no local supplement identified.
Private wells & water rights
Generally allowedPrivate wells are permitted through the Alleghany Health District under the state's well regulations, with site sketches and applications submitted to the health department; no separate county water-rights ordinance exists. source
Living disconnected from utilities
Unclear - verifyNo Alleghany County ordinance was found that explicitly requires connection to electric utility service, but zoning, building, and health department approvals still function as practical requirements for any occupied dwelling, grid-tied or not.
