Davidson County, North Carolina requires a building permit before you build, and the county's own Inspections Department, not a city, issues it for unincorporated land under the North Carolina State Building Code1. The county also runs its own comprehensive zoning program through Planning & Zoning Permits, covering land outside any city's jurisdiction2. If your land isn't on public sewer, Environmental Health issues the Improvement Permit and Construction Authorization your septic system needs before Inspections will issue a building permit3.

Do you need a building permit in Davidson County, North Carolina?
Yes, for construction in unincorporated Davidson County. The county's Inspections Department is authorized by North Carolina General Statutes to enforce the state Building Code, and its primary job is reviewing plans and issuing building, electrical, plumbing and mechanical permits4. This runs through the county directly rather than a city, because North Carolina's building-code jurisdiction splits by area: a municipality's jurisdiction covers its corporate limits and any extraterritorial area, and the county covers everything else11. Manufactured and modular homes go through the same office, and North Carolina law requires a building permit from the Building Official before you install, alter or repair a manufactured home, separate from any warranty repair exception49. One real exception: a farm building located outside a municipality's building-code jurisdiction, so most rural farm buildings in Davidson County, is exempt from the building rules altogether, along with primitive camps and primitive farm buildings12.
Who is the Davidson County building department, and how do you reach them?
Inspections / Central Permitting sits at 912 Greensboro Street in Lexington, reachable at 336-242-2230, with permits issued between 8:30 a.m. and 4:30 p.m. on weekdays4. Apply for building permits and schedule inspections through the county-linked OpenGov portal; Inspections accepts plans for review and issues the permits13. Planning & Zoning publishes the county zoning ordinance, subdivision regulations and land development plan, and its zoning official can answer residential or commercial permitting questions at 336-242-2220135. Environmental Health can be reached at 336-242-2310 for septic permitting questions6.
Does Davidson County have zoning?
Yes. Davidson County runs its own comprehensive zoning program for unincorporated land through Planning & Zoning Permits, and North Carolina law lets a county apply zoning to all or part of its planning and development jurisdiction outside any city's own jurisdiction214. There's an important exception for working farms: North Carolina law says county zoning regulations may not affect property used for bona fide farm purposes, covering crops, livestock, dairy, poultry and related activities, plus a farm residence and supporting buildings, though this doesn't exempt nonfarm uses on the same land8. Tiny houses are treated as regulated dwellings, not an exempt category: North Carolina's Residential Code has an appendix specifically for tiny houses used as a single dwelling unit (400 square feet or less, excluding lofts), and they still have to comply with the Code except where that appendix says otherwise15.
How do septic permits work in Davidson County?
Environmental Health, not Inspections, handles septic: an Improvement Permit and a Construction Authorization are required before you construct, locate, relocate, install or repair a wastewater system, unless you use the engineered option permit or an Authorized On-Site Wastewater Evaluator instead616. Routine maintenance of an existing system doesn't need a new permit, so day-to-day upkeep is separate from these construction-stage approvals16. Soils in Davidson County give a buyer real options: USDA survey data rates about 37% of the county's soil as free of severe limits for a conventional drain field, meaningfully better than many counties on this site, though Environmental Health still has to evaluate your specific site before you can count on a standard system10.
Can you live in an RV or tiny home on your land in Davidson County?
A tiny home in North Carolina is a regulated dwelling unit under Appendix AQ of the state Residential Code, not an exempt category, so it needs the same building permit and code compliance as any other home, just under that appendix's specific provisions15. Whether your Davidson County parcel's zoning allows a tiny home or RV as a residence, temporarily or long-term, is a Planning & Zoning question, since the county administers its own zoning outside city limits52. Call the zoning official at 336-242-2220 before you buy if RV or tiny-home living is part of your plan, and ask about your specific parcel's zoning district rather than assuming a countywide answer5.
Building a home in Davidson County: the steps, in order
- Call Planning & Zoning at 336-242-2220 to confirm your parcel's zoning district and whether your planned use is allowed5.
- If a subdivision plan uses a new access easement serving two or more proposed lots, obtain NCDOT driveway approval and build the easement before seeking the zoning permit17.
- If you're not on public sewer, apply to Environmental Health at 336-242-2310 for an Improvement Permit and Construction Authorization before finalizing your house plans6.
- If the property is a working farm, ask whether your planned structure qualifies for the bona fide farm exemption from zoning or the farm-building exemption from building rules812.
- Apply for the building permit through the county-linked OpenGov portal; Inspections accepts plans for review and issues permits13.
- Schedule required inspections through the same portal as construction proceeds1318.
- Complete the final inspection and obtain the required certificate before moving in19.
What to check before you buy land in Davidson County
Confirm the parcel's zoning district with Planning & Zoning, and ask whether the land currently qualifies for the bona fide farm exemption, since that changes the zoning picture58. Ask Environmental Health for a soil evaluation before closing if there is no public sewer; about 37% of county soil rates free of severe limits for a conventional drain field, but the parcel still needs its own evaluation106. For a proposed subdivision in which a new easement would serve two or more lots, budget time for NCDOT driveway approval and construction of the easement before the zoning permit17. Ask Inspections about floodplain requirements for flood-prone land because the department enforces the floodplain ordinance4. The effective property tax rate is about 0.6%, and the median annual bill is about $1,2622021.
Watch-outs
- Davidson County exists in North Carolina, not to be confused with Davidson County, Tennessee (Nashville); confirm any search result or citation names North Carolina and shows a 336 area code before relying on it4.
- Owner-builder exemption status is not confirmed on Davidson County's official sources; ask Inspections / Central Permitting directly whether a homeowner can act as their own contractor before you plan around it7.
