Do I need a permit for fence installation or replacement in Cary?
It depends. Whether fence installation or replacement needs a permit in Cary comes down to the details of your project.
The Town of Cary lists most residential fences as not requiring a building permit, unless the fence is on a Collector Street or Thoroughfare, so a typical interior-lot fence generally does not need a building permit but is still subject to the Town's fence regulations. Installing or replacing a pool barrier fence does require a permit under Cary's rules, since it is a required safety barrier for a pool, spa, or hot tub. Check the Town of Cary Fence Regulations page and contact Planning and Development Services about location and height limits before installing, since front, corner, and thoroughfare situations differ. A tall fence is more likely to need a permit, but North Carolina sets no statewide fence height line. Confirm the threshold with your local inspections or planning department before you order materials. Wake County's own permitting office is Wake County Permits and Inspections. It issues permits for the unincorporated county, and in North Carolina the county is often the building authority even inside city limits, so confirm which applies to your address. Fences are usually a zoning review rather than a building permit, and the zoning office may be separate from the building office. North Carolina sets no statewide fence height. The North Carolina Administrative Code and Policies has no work-exempt-from-permit list of the model code kind, and the statewide line is a cost test: under NCGS 160D-1110(c) no permit is required for work costing forty thousand dollars or less in a single-family residence, done to the State Building Code, unless it falls into one of the listed categories such as load-bearing structures or changes to plumbing, heating, air conditioning or electrical design. Many North Carolina jurisdictions do not require a building permit for a standard residential fence, but height limits, corner-visibility and setback rules still apply and some towns require a zoning permit. Confirm with your local planning or inspections department. A fence serving as a swimming pool barrier must meet the NC Residential Code pool-barrier requirements and is inspected as part of the pool permit.
