Small commercial buildings often still need energy compliance documentation. Even when the project is not large, the building department may require a COMcheck report to verify envelope, lighting, or mechanical compliance. For contractors and small commercial project teams, understanding when COMcheck applies can prevent last-minute permit delays.
COMcheck may be required for:
- Small office buildings
- Retail spaces
- Restaurants
- Tenant buildouts
- New commercial shells
- Change-of-use projects
- Additions to commercial buildings
The exact requirement depends on the jurisdiction, adopted code, and project scope.
COMcheck can document compliance for:
- Building envelope assemblies
- Window and glazing performance
- Interior lighting power
- Exterior lighting power
- Lighting controls
- Mechanical systems
Some projects only need certain sections, while others require a more complete report.
Small commercial projects often run into problems when the team assumes energy documentation is not required. Other common issues include missing lighting schedules, incomplete mechanical equipment data, and unclear separation between existing and new work.
Tenant improvements can be especially tricky because the base building may already exist, but new lighting or HVAC work can still trigger compliance documentation.
Before ordering a COMcheck report, gather:
- Architectural plans
- Project address and jurisdiction
- Building use or occupancy
- Lighting fixture schedule
- Mechanical equipment schedule
- Envelope details, if applicable
- Scope of new versus existing work
This helps the report match the actual permit scope.
Do small commercial buildings always need COMcheck?
Not always. Requirements depend on the jurisdiction, code edition, and project scope.
Can tenant improvements require COMcheck?
Yes. Lighting, HVAC, or envelope changes can trigger COMcheck documentation.
What information is most important for COMcheck?
Lighting schedules, mechanical equipment data, envelope details, and the project scope are key inputs.
