Off-Grid Living in Poquoson city, Virginia

Poquoson is a bit of a special case in Virginia: it's an independent city, which means it isn't nested inside any county. The city itself functions as both the "county" and "town" level authority for zoning and building, while environmental health (septic, wells, greywater, rainwater) stays with the state through the Virginia Department of Health (VDH), same as everywhere else in Virginia.

Zoning. Poquoson has a full, adopted zoning ordinance (codified in the City Code) with residential districts like R-1, R-2, and R-3, plus a Board of Zoning Appeals. There's no "no zoning" pocket of raw land here that I could find. If you're picturing living off-grid in a tent or unpermitted structure on vacant land, that would run into the same district-use and building-permit rules as any other structure, since I found no carve-out for off-grid or raw-land occupancy.

Dwellings, tiny homes, RVs. I could not locate a Poquoson-specific ordinance addressing tiny houses or RV occupancy directly. My honest read is that the state baseline probably applies, meaning RVs and tiny homes on wheels are generally treated as vehicles, not permanent dwellings, and likely can't be used as a permanent residence outside a licensed park. But since I didn't find Poquoson's own wording on this, treat it as unconfirmed and ask the Permit Office directly.

Building permits. The City's Permit Office, part of Community Development, issues building and zoning permits and enforces Virginia's Uniform Statewide Building Code locally. Applications go through the city's online Permit Portal.

Septic and wells. Both are regulated by the state, not the city. VDH's Sewage Handling and Disposal Regulations and Private Well Regulations cover this, and you'll typically need a permit for either before Poquoson issues a building permit. I could not confirm exactly which VDH health district office currently handles Poquoson day-to-day, so call around if the number I found doesn't route you correctly.

Greywater and rainwater harvesting. Both fall under VDH's onsite water/wastewater program statewide. Rainwater harvesting has a Tier 4 permit path and a registration option for non-potable systems through VDH. No Poquoson-specific rule was found for either, so the state framework is what governs.

Off-grid electric. I didn't find any Poquoson ordinance requiring a grid electric hookup for occupancy. That said, you'll still need an approved water supply and sewage disposal system, plus a building permit and certificate of occupancy, before the city will sign off on a dwelling. Whether skipping grid power alone is a problem is not confirmed either way.

Bottom line: Poquoson runs its own zoning and building permitting since it's an independent city, but for water, septic, and rainwater, you're dealing with the state through VDH. Given several unconfirmed points here, a call to the Permit Office is worth it before you commit to a plan.
