Grayson County, Virginia requires a building permit for a new home, issued by the Grayson County Building Department, which also serves the towns of Independence, Fries and Troutdale.1 Zoning permits come from county Planning and Zoning in unincorporated areas, while those three towns administer their own zoning.2 Septic and well approval come from the Grayson County Health Department, and a home without public sewer or water needs that approval before the building permit.34

Do you need a building permit in Grayson County, Virginia?

Yes. Grayson County's Building Department requires a Residential Permit Application before construction, alteration or demolition of a residential building; permit requirements depend on the work, and limited exceptions apply6. An approved zoning permit must precede the building permit, and projects without public sewer or water also need health-department approval for the septic system and well14. Virginia's Uniform Statewide Building Code supplies the construction standards enforced locally15. Grayson County allows an owner to act as general contractor on the owner's project by filing the county affidavit, but every hired contractor must hold the license for that trade and provide a name and license number with the application9. A certificate of occupancy is required before occupancy or a change of occupancy16.

Farm buildings are treated differently: a structure used only for farming, on the property where the farming happens and not used as a residence, is exempt from the building code with an Agricultural Exemption affidavit, and the same affidavit shows a bona fide farm operation for a zoning-permit exemption.13 Farm structures in a floodplain still face flood-proofing rules.13

Who is the Grayson County building department, and how do you reach them?

The Grayson County Building Department issues building permits, reviews plans, and inspects projects in Grayson County and the Towns of Independence, Fries and Troutdale1. It's at 129 Davis Street, PO Box 217, Independence, VA 24348, and the phone is 276-773-23221. Zoning is a separate department in the same building: the Planning and Zoning Department handles zoning permits, subdivision review, floodplain permits and erosion-and-sediment-control approval, at 276-773-200017. Septic and well approvals go through the Grayson County Health Department, part of the Virginia Department of Health's Mount Rogers Health District, at 186 West Main Street, Independence, VA 24348, phone (276) 773-29614.

Does Grayson County have zoning?

Yes, in unincorporated areas. Grayson County publishes Rural Farm, Rural Residence, commercial, industrial, public, service and shoreline districts, with district-specific uses and development standards; Fries, Independence and Troutdale administer their own zoning, so a parcel inside one of those towns starts with the town's zoning office, while septic and well approval still go through the Grayson County Health Department.18194 Ask Planning and Zoning to identify the official district before applying its rules1718. Class I and Class II subdivision lots for detached single-family homes generally need at least 30,000 square feet and 100 feet of width at the building line, but septic needs and the zoning district can require more10. Single-family manufactured homes are permitted uses in both Rural Farm and Rural Residential, subject to the applicable lot, setback, access, permit and health requirements2021. In both districts, residential density is capped at three detached single-family dwellings per parcel of record, manufactured homes included.22 A manufactured-home park requires a special-use permit in the Rural Farm or Commercial district23.

Bed-and-breakfasts, lodges and inns of six bedrooms or fewer are permitted in the Rural Farm district and need a special-use permit in the Rural Residential district; the ordinance does not clearly address every other short-term-rental arrangement, so ask Planning and Zoning.2417

How do septic permits work in Grayson County?

Virginia law requires written health-department authorization before Grayson County can issue a building permit for a building designed for human occupancy, and a written construction permit is required before an onsite sewage system is built, expanded or modified8. Start with the Grayson County Health Department, the local Virginia Department of Health office for septic and private-well approvals4. Once installed, the system cannot be covered or used until the required inspection and approval, although a qualifying licensed designer's inspection report can substitute in the circumstances the rule allows25. Only 4.2% of Grayson County soils are rated without severe limitations for a conventional septic drain field, so make the site and soil evaluation an early purchase contingency rather than assuming a preferred house site will work26.

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

On a lot of record in unincorporated Grayson County, no more than 2 RVs or camping units are allowed; each RV must either remain fewer than 180 consecutive days and stay licensed and highway-ready, or meet the building-code permit, placement, elevation and anchoring requirements for a manufactured home12. More than 2 units is a campground, and a campground or RV park requires a special-use permit in the Rural Farm or Commercial district12. A tiny dwelling of 400 square feet or less may use Appendix AQ as an alternative residential-code path, but it still must comply with zoning, building permits, inspections and septic requirements11. That code option does not decide which parcel or district can host a particular design, so take the plans to Planning and Zoning before purchase or construction1117. Virginia's accessory dwelling law, effective July 1, 2027, will require localities to treat accessory dwelling units as a permitted accessory use in single-family residential districts, subject to listed conditions.27

How do you build a home in Grayson County, Virginia?

  1. Ask Planning and Zoning to confirm the parcel's district and approve the zoning permit required before a building permit1417.
  1. If public sewer or water is unavailable, obtain septic and well approval through the Grayson County Health Department; the septic construction permit must precede system work84.
  1. Submit the residential application and plans to the Building Department; an owner-builder must file the county affidavit and identify licensed contractors performing trade work69.
  1. Obtain any required VDOT entrance and erosion-control approvals, then schedule the county's construction inspections281429.
  1. After final approval, obtain the certificate of occupancy before moving in16.

What should you check before buying land in Grayson County?

Confirm the zoning district with Planning and Zoning and compare the intended home, RV or manufactured home with that district's use and dimensional standards1718. If land will be divided, do not assume the base 30,000-square-foot lot is enough: Class I and Class II lots also face width, zoning and septic constraints10. Only 4.2% of Grayson County soils are rated without severe limits for a conventional septic drain field, while just 29.8% of county land has a slope of 15% or less, so verify a workable house, driveway and drain-field area before closing2630. Development in a mapped floodplain requires a zoning permit and can require engineering support31. The effective property-tax rate is about 0.6%, and the median annual property-tax bill is about $8203233.

Watch-outs

  • There is another Grayson County in Texas; confirm you're looking at graysoncountyva.gov before calling or citing any office in this guide1.
  • Do not assume a town's rules match the county's: Fries, Independence and Troutdale zone their own land, but septic and well approvals stay with the Grayson County Health Department.194
  • An RV that remains for 180 consecutive days or longer must meet manufactured-home placement standards, while a tiny dwelling still needs parcel-specific zoning approval; take either plan to Planning and Zoning before relying on it121117.
