Do you need a building permit in King William County, Virginia?

Yes. King William County administers the Virginia Uniform Statewide Building Code, and a new home requires county building permits and inspections1. Virginia requires a permit application to the building official before covered construction, demolition or regulated installation work begins9. The county Building Department reviews plans for new construction and inspects residential and commercial properties for compliance with building codes and county ordinances10. Inspections are required at multiple stages, with a final inspection required before the certificate of occupancy is issued2. A qualifying farm building used primarily for farming and not for residential purposes is exempt from the state Building Code, although floodplain rules still apply in a floodplain11. King William County publishes its own building-fee schedule and adds a 2% state levy to the listed fee12.

Who is the King William County building department, and how do you reach it?

The King William County Building Department handles new-construction plan review, code compliance and building inspections10. The office is at 180 Horse Landing Road #4, King William, VA 23086; call 804-769-4969 or email [email protected]10. Planning & Zoning is at the same address and can be reached at 804-769-4980 for zoning, land-disturbance and subdivision questions13. Both building and land-use applications have access to the county's online public portal13. Start with Planning & Zoning to confirm the parcel's district and proposed use, then use the Building Department for construction documents, the building application, inspection scheduling and the certificate-of-occupancy path13105.

Does King William County have zoning?

Unincorporated King William County is subject to the county's Zoning & Subdivision Ordinance14. Incorporated municipalities may exercise separate authority, so a West Point address should not be assumed to follow the county's unincorporated-area rules1415. Zoning can regulate uses, structures and dimensional standards, which means setbacks, building height, minimum home size, lot coverage, RV occupancy and tiny-home occupancy must be checked against the parcel's district15. We could not confirm a complete countywide answer for those parcel-specific standards; ask Planning & Zoning for the district, use status and dimensional schedule before choosing a house plan or placing an RV313. The published lot-size figure concerns a large-animal veterinary hospital in one zoning district, not a general residential minimum, so it should not be used to size a homesite16.

How do septic permits work in King William County?

Onsite sewage permitting in King William County is administered under the Virginia Department of Health framework, and the county identifies a VDH sewage-disposal permit as a prerequisite to the building permit4. Virginia requires a written construction permit before an onsite sewage system is constructed, expanded or modified6. Contact the King William County Health Department at 172 Courthouse Lane, King William Courthouse, VA 23086, or 804-769-4988, and ask for onsite sewage and private-well services17. After installation and the applicable inspection path, an operation permit is needed before the local building official can issue a certificate of occupancy1819. Only about 10.4% of county soils are rated without severe limits for a conventional septic drain field, so make the site and soil evaluation an early purchase contingency rather than assuming a conventional system will fit20.

Can you live in an RV or tiny home on your land in King William County?

We could not confirm a blanket rule allowing long-term RV occupancy or tiny-home occupancy on private land in unincorporated King William County. The county does have zoning, so the answer can depend on the parcel's zoning district, the proposed use and whether the structure is treated as a dwelling315. Virginia's campground regulation governs permitted campgrounds and does not establish a right to live in an RV on an individual parcel21. A tiny home used as a dwelling still enters the county's building-permit and certificate-of-occupancy process when it is regulated as residential construction119. Before buying or moving anything onto the land, give Planning & Zoning the tax parcel and describe whether the unit has wheels, a foundation, utility connections and full-time occupancy13.

Building a home in King William County, Virginia: the steps in order

  1. Ask Planning & Zoning to confirm the parcel's zoning district, proposed residential use and applicable dimensional standards313.
  1. Arrange the onsite sewage and private-well review with the King William County Health Department when the property will not use public service417.
  1. Obtain the written sewage construction permit before installing or modifying an onsite system6.
  1. Apply to the King William County Building Department before covered construction begins; an owner acting as contractor must complete the county affidavit and meet its conditions97.
  1. Obtain a VDOT land-use permit before building or changing an entrance on a VDOT-maintained highway8.
  1. Schedule the county's required construction inspections and complete all applicable health and zoning approvals25.
  1. Obtain the certificate of occupancy before moving into the home19.

What should you check before buying land in King William County?

Start with buildability: confirm the zoning district and proposed use with Planning & Zoning, then make septic suitability a contract contingency because only about 10.4% of county soils are rated without severe limits for a conventional drain field31320. Check whether the entrance touches a VDOT-maintained highway, since work in that right-of-way needs a state land-use permit8. Ask the building official about flood-hazard status because work otherwise exempt from a building permit may still require one in a special flood hazard area22. The land is broadly gentle and wooded, with about 87% at a slope of 15% or less and 65.4% forest cover, but parcel-level clearing, drainage and access costs can still vary2324. For carrying costs, the county's effective property-tax rate is about 0.6%, and the median property-tax bill is about $1,733 a year2526.

Watch-outs

  • Do not start with the house plan alone: King William County requires health and zoning approvals to be finalized along with the final inspection before issuing a certificate of occupancy5.
  • Only about 10.4% of King William County soils are rated without severe limits for a conventional septic drain field, so verify a workable system before closing on rural land20.
  • King William County's RV, tiny-home, setback and minimum-dwelling-size answers were not confirmed as blanket rules; ask Planning & Zoning about the specific parcel313.

Water rights & wells in King William County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Virginia’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

Household wells are exempt from the groundwater withdrawal permit even inside a Groundwater Management Area, but a private well in a GWMA must be registered with DEQ within 30 days (Va. Code 62.1-258); a permit is triggered only at 300,000 gal/month.

Limit: < 300,000 gal/month (no withdrawal permit)
