What Is an NRCC Form?
The NRCC is the Certificate of Compliance for a nonresidential project — the design-stage document submitted with the permit application. Unlike a residential certificate, it is split into separate parts by discipline.

Split by discipline, not by building
A house is documented on one certificate. A commercial project is documented discipline by discipline: separate NRCC parts cover the envelope, indoor lighting, outdoor lighting and mechanical systems, and a project completes the parts that match its scope.
That is why asking "do I need an NRCC" is really asking which parts apply, and why a lighting-only tenant improvement produces a much thinner submittal than a restaurant fit-out touching three or four disciplines at once.
Which buildings use it
Nonresidential buildings, hotels and motels, and high-rise multifamily — meaning multifamily of four or more habitable storeys above grade. Low-rise multifamily, up to three habitable storeys, uses the LMCC family instead. Because the split is decided by habitable storeys, a design close to that boundary should have it settled before the documents are started.
The three stages
NRCC at design stage, NRCI as a Certificate of Installation during construction, and NRCV as a Certificate of Verification where third-party testing applies — the same design/installation/verification pattern the residential and multifamily families follow.
Acceptance testing is the part underestimated
Certain lighting controls and mechanical systems have to be demonstrated to work after installation rather than merely specified. That happens on site near the end of the job and is signed off by the party carrying out the test, so it is a programme item as much as a paperwork one. Identifying it at design stage is considerably cheaper than discovering it at final inspection.
