What Is Included in a Commercial Title 24 Report?
The NRCC certificate of compliance parts covering the disciplines your project actually touches — envelope, indoor lighting, outdoor lighting and mechanical — prepared from your drawings and submitted with the permit application.
Split by discipline, not by building
A residential report is one certificate. A commercial submittal is the set of NRCC parts matching the systems in scope, which is why two projects of the same size can produce very different amounts of paperwork. A lighting-only tenant improvement produces one discipline; a restaurant fit-out touching envelope, lighting and mechanical produces three.
What the compliance set demonstrates
First the classification: whether the work is new construction, an alteration under Section 141.0(b), or an addition. Then, for the components in scope, that the design meets the applicable requirements — either prescriptively, or on the performance path by modelling against a standard design.
For lighting that means the area-by-area power allowance and the control scheme. For mechanical it means equipment efficiency, the controls of Sections 110.2 and 120.2, and the economizer requirement where cooling capacity exceeds 33,000 Btu/hr.
What comes after, and is not in the report
Two further document families the project will need, which are commonly assumed to be part of the report and are not. The NRCI certificates of installation are completed during construction by the contractors who install the regulated work. The NRCA certificates of acceptance record functional testing of lighting controls and mechanical systems, performed by a certified acceptance test technician.
A commercial project is not finished when the report is issued. It is finished when those tests pass.
What we need to produce it
The floor plan with the use of each space named, the reflected ceiling plan and lighting schedule with input wattages, and whatever defines the mechanical scope. Where the base building services are untouched, saying so explicitly removes a question rather than leaving it to be inferred.
