Zoning, building permits and septic rules in Apex, North Carolina

The Town of Apex, North Carolina, in Wake County, runs its own zoning under a Unified Development Ordinance1 and its own building permit desk2. Septic permits and private wells are not decided by the town: Wake County Onsite Water Protection handles them3. Outside town limits, Wake County's rules apply instead, not Apex's.

Does Apex, NC have zoning, and what does it mean for lot size and height?

Yes. The Town of Apex adopts and enforces its own zoning for land inside town limits, and the Unified Development Ordinance establishes 39 zoning districts5. Any use or development must comply with the district the parcel sits in1.

Dimensions depend on the district. In the Residential Agricultural (RA) district, single-family homes must have an average lot size of 5 acres or greater6, built-upon area is capped at 50 percent10, and height is capped at 36 feet11. In the Rural Residential (RR) district, the average lot size drops to 1 acre or greater7.

We could not confirm Apex's rules for living in an RV, tiny homes, accessory dwellings or short-term rentals. Ask Apex Planning at the office listed below12.

Do you need a building permit in Apex, and who issues it?

Yes. Building permits inside Apex are issued by the town's own permits desk, not by Wake County2. Most residential projects use the town's one- and two-family permit application, and residential single-trade electrical, mechanical and plumbing permits must be submitted by a licensed contractor4.

North Carolina law generally requires a permit before building work begins, with an exemption for some qualifying work costing $40,000 or less on a single-family residence, farm building or commercial building13. That exemption does not cover electrical, heating or cooling changes13.

A final inspection is required at the end of permitted work, and a building generally cannot be occupied until a certificate of compliance is issued14. We could not confirm whether Apex offers an owner-builder exemption; ask the permits desk.

How much do building permits and inspections cost in Apex?

Apex charges $100 for the Final Water Resources Inspection on new commercial and one- and two-family dwelling permits issued on or after July 1, 2018, and $75 for each failed inspection15. We could not confirm the complete building permit fee schedule, so call the permits desk for the total on your project2.

How do septic permits and wells work in Apex?

Septic permits and private wells inside Apex are not decided by the town. Wake County Onsite Water Protection issues permits, inspects septic systems and private wells, and responds to complaints3. State law requires an improvement permit and construction authorization from the local health department before a residence is built in an area not served by an approved wastewater system8.

Many Apex lots are on town sewer instead. Residential connections to Town water and sewer need availability confirmed, a permit and connection form, and inspections, and sewer is offered only to customers who have or will connect to town water9. We could not confirm Apex-specific septic and well rules for lots that cannot connect, so ask Wake County Onsite Water Protection before you buy.

Building a home in Apex: the steps, in order

  1. Confirm the parcel's zoning district and lot standards with the Town of Apex Planning Department112.
  2. Check whether the parcel is in the floodplain; a floodplain development permit is required for any manmade change to real estate there, and no new residential lots are allowed in the floodplain16.
  3. Find out whether town water and sewer reach the lot, or arrange septic and a well with Wake County Onsite Water Protection93.
  4. Submit the building permit application at the Apex permits desk24.
  5. Pass inspections as work progresses17.
  6. Obtain a certificate of compliance before anyone moves in14.

What stays with Wake County, and what to check before you buy near Apex

Apex's rules apply only inside its limits. For land outside town limits, use the Wake County page and Wake County's own permit and planning offices instead. Within the county, the Wake County effective property tax rate is 0.7 percent18 and the median property tax bill is $3,023 a year19.

Septic permits and wells stay with Wake County Onsite Water Protection3. Subdividing land is regulated by the Unified Development Ordinance inside town limits20.

Watch-outs

  • Apex's rules end at town limits; a parcel with an Apex mailing address may lie outside town limits and fall under Wake County, so confirm with Apex Planning12.
  • We could not confirm Apex's rules for RV living, tiny homes, accessory dwellings or short-term rentals; ask Apex Planning before relying on any of them12.
  • Commercial projects need Planning approval before the permit application can be submitted4.
