37.4626, -79.1185 · 853 ft elevationRead this before you act on anything below. This is my researched starting point for Amherst 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 rulesAmherst County, VA
Zoning & raw-land occupancy
Varies locallyAmherst County has countywide zoning administered by its Planning & Zoning Department, and the Town of Amherst has its own separate zoning and subdivision ordinance for in-town parcels. I couldn't confirm specifics on minimum acreage or occupying raw land without a permitted structure, so check with whichever authority covers your parcel. source
Dwellings, tiny homes & RVs
Unclear - verifyI didn't find Amherst County-specific language on tiny homes, Appendix Q adoption, or RVs as residences, so this likely falls back to Virginia's statewide building code baseline. Any dwelling type still needs to go through the county's zoning and building permit process, so ask the Building Official before you build or park.
Building permits & codes
Generally allowedBuilding permits are mandatory and handled by the Amherst County Building Inspections Department, even for property inside the Town limits, and you'll need an approved zoning permit plus septic/well approval before submitting. Small accessory structures under 256 sq ft and small pools are exempt from permitting. source
Septic & composting toilets
Generally allowedA septic permit from the Central Virginia Health District (a VDH office) is required before the county issues a building permit. Composting toilets and privies appear to be governed by the same statewide VDH regulation, though I didn't find an Amherst-specific addition beyond the state rule. source
Greywater reuse
Unclear - verifyI found no Amherst County ordinance or Central Virginia Health District page specifically covering greywater reuse. This likely runs through Virginia's statewide greywater rules via the same local health department that handles septic and well permits, so confirm directly with that office.
Rainwater harvesting
Generally allowedRainwater harvesting is addressed at the state level by VDH, which runs a Tier 4 permit and registration process for non-potable systems. No Amherst County supplement to this state program was found, so the state process is what applies here. source
Private wells & water rights
Generally allowedA well permit from the local VDH office (Central Virginia Health District) is required before the county issues a building permit, and it's often processed jointly with the septic permit. Fees referenced in a 2021 VDH document may be outdated, so confirm current figures directly with the health department. source
Living disconnected from utilities
Unclear - verifyI found no Amherst County ordinance requiring a grid electric hookup, and off-grid solar/battery power doesn't appear restricted in the sources I reviewed. That said, the permit sequence of zoning, then septic/well, then building permit means any legally occupied dwelling still needs approved water and waste systems regardless of your electrical setup.
