Apex FAQ
Where are smoke alarms required in an Apex NC home?
Under NC Residential Code Section R314.3 (currently the 2018 NCRC, enforced by Apex Code Enforcement), smoke alarms are required in each sleeping room, outside each separate sleeping area in the immediate vicinity of the bedrooms, and on each additional story of the dwelling - including basements and habitable attics but excluding crawl spaces and uninhabitable attics. In split-level dwellings without an intervening door, an alarm on the upper level suffices for the adjacent lower level if it is less than one full story below.
Do smoke alarms have to be interconnected in Apex?
Yes. NC Residential Code R314.4 requires that where more than one smoke alarm is required, the alarms must be interconnected so that actuation of any one activates all alarms in the dwelling. Listed wireless interconnect alarms satisfy this requirement. Physical interconnection is not required in existing areas where alterations or repairs do not expose the structure (R314.6). New construction also requires building-wiring power with battery backup under R314.5.
What edition of the NC Residential Code applies in Apex?
The 2018 NC Residential Code is currently in effect statewide. The 2024 NC State Building Code (which includes the 2024 NCRC) is delayed; per S.L. 2025-2 the earliest effective date is July 31, 2026, and the rollout depends on NC OSFM certifying publication. House Bill 488 (S.L. 2023-108) also restructured how the Residential Code is amended - the new Residential Code Council holds that authority and major revisions are deferred to the next six-year cycle effective January 1, 2031.

Yes for homes built or substantially renovated since June 30, 1999. NCRC §R314.3 also requires one within 10 feet of every sleeping area and at least one on each story, including basements.
