Do you need a building permit in Henry County, Virginia?
Yes. Henry County's Department of Planning, Zoning and Inspections regulates, permits and inspects new homes, additions, alterations, manufactured-home placement, subdivision development and land disturbance1. Virginia's current statewide code edition is the 2021 Uniform Statewide Building Code, effective January 18, 2024, and the county building department enforces it locally11. Apply to the building official before covered work starts; Virginia allows applications by mail or through an online process where the locality offers one, and an applicant cannot be required to appear in person12. Henry County's published fee schedule charges residential new construction at $0.08 per square foot, including electrical, plumbing and mechanical work, with a $25 minimum, and adds a 2% state tax13. Permit exceptions may apply under the statewide code, so describe the exact project to Building Inspection before assuming small or accessory work is exempt1.
Who is the Henry County building department, and how do you reach them?
Henry County Building Inspection is reached at 276-634-4615, in Room #205 of the Henry County Administration Building at 3300 Kings Mountain Road in Martinsville14. Zoning, rezoning, special-use permits and variances go through Henry County Planning & Zoning at 276-634-4620 in the same building152. Once a permit is issued, the building official conducts the applicable inspections, including footings, foundations, structural framing and utilities before concealment, followed by a final inspection16. Henry County's fee schedule also sets a $10 charge for an extra inspection trip caused by listed problems such as work not being ready or corrections not being made17. A certificate of occupancy is required before occupancy of a regulated new building and is issued within five working days after final-inspection approval and a compliance determination18.
Does Henry County have zoning?
Yes. Henry County administers zoning and subdivision ordinances, including rezoning, special-use permits and variances that go before the Planning Commission or Board of Zoning Appeals2. County zoning jurisdiction covers unincorporated territory, while an incorporated municipality controls zoning within its own boundaries19. Henry County also regulates subdivision development, so splitting acreage is not merely a deed-recording exercise20. The available rules do not confirm one countywide residential setback, minimum lot size, minimum home size, accessory-dwelling rule or tiny-home standard; ask Planning & Zoning for the parcel's district and the standards that attach to it155. A qualifying nonresidential farm building used primarily for farm purposes is exempt from the statewide Building Code, but flood-proofing requirements still apply in a floodplain21.
How do septic permits work in Henry County?
Septic is a state function here, not a county one: Virginia's Department of Health has statewide supervision and control over onsite sewage systems, and local or district health departments, not the county government, handle applications, inspections and permits622. For Henry County that's the Henry/Martinsville Health Department, part of the West Piedmont Health District, at 295 Commonwealth Boulevard in Martinsville (276-638-2311)23. No one may construct, operate, expand or modify a sewage disposal system without a written permit from the state, and the standard application fee is $75, with waivers available for applicants below federal poverty guidelines or for a pit privy or repair of a failing system4. Soils are mixed here: only about 27.6% of Henry County's soils rate free of severe limitations for a conventional septic drain field under the USDA soil survey, so budget time and money for a site evaluation on much of the county's land24. Systems not built under a licensed professional engineer's or onsite soil evaluator's certified design must be inspected and approved by the health department before any part is covered or used25.
Can you live in an RV or put a manufactured home on your land in Henry County?
Virginia requires manufactured homes to be allowed in an agricultural zoning district, or a similar district dominated by farm or forest uses, when site-built housing is allowed there7. In other districts where site-built housing is allowed, a manufactured home must be converted to real property, have a certificate of occupancy issued within five years of the data-plate manufacture date and occupy an individual lot7. Henry County treats manufactured-home placement as regulated development1. We could not confirm a Henry County rule for living in an RV on a private parcel, temporary camping on private land or occupancy of a tiny home; call Planning & Zoning at 276-634-4620 with the parcel number and proposed use155. Virginia's separate temporary-camping limits apply to regulated campgrounds and do not answer whether a landowner may occupy an RV on a private homesite8.
Building a home in Henry County: the steps, in order
- Call Henry County Planning & Zoning at 276-634-4620 to confirm the zoning district, proposed use and parcel-specific dimensional standards152.
- Apply for a septic construction permit with the Henry/Martinsville Health Department at 276-638-2311 when the parcel lacks public sewer233.
- Obtain a VDOT land-use permit before constructing or modifying an entrance to a state-maintained highway10.
- Apply to Henry County Building Inspection at 276-634-4615 before covered work begins; the county's process is published only in part, so ask which plans and supporting approvals your project requires142612.
- Schedule each applicable inspection before work is concealed and arrange the final inspection when construction is complete16.
- Obtain the certificate of occupancy before moving into the completed home18.
What to check before you buy land in Henry County
Start with septic and soils: only about 27.6% of Henry County's soils rate free of severe limitations for a conventional drain field, so ask the Henry/Martinsville Health Department about site evaluation before you count on a standard system2423. Ask Planning & Zoning which zoning district the parcel sits in and whether it's in a mapped special flood hazard area, since a building permit can be required there even for work that would otherwise be exempt1527. If access runs to a state road, confirm whether the existing entrance already has a VDOT land use permit or whether you'll need to apply for one10. Henry County is genuinely rural: about 49,702 people at 130 people per square mile, 82.1% wooded, with 44.6% of land at gentle slope, and the nearest city of 100,000 or more people is about 42 miles away2829303132. Typical home value runs around $142,929, and Henry County's property taxes are light for the region: a median bill near $604 a year at an effective rate of about 0.5%333435.
Watch-outs
- We could not confirm whether Henry County allows residential RV occupancy on a private parcel; the available state rule covers regulated campgrounds, so ask Planning & Zoning before relying on an RV during a build815.
- The county's own pages do not state an owner-builder exemption from the building permit requirement; confirm directly with Henry County Building Inspection14 rather than assuming one exists9.
- Septic permitting in Henry County runs through the state Health Department, not the county government; don't call the county building department expecting them to issue it6.
