Commercial Energy Compliance & NRCC

Commercial and tenant-improvement documentation, scoped by system

This service supports owners, architects and commercial design teams preparing NRCC design-compliance documentation for affected nonresidential systems. That may be a tenant fit-out, a lighting alteration, mechanical work, envelope changes or a broader coordinated package. We identify the actual scope before treating “commercial Title 24” as a single report or assuming a shell approval covers later tenant work.

For permit applications on or after January 1, 2026, current guidance uses the 2025 California Energy Code. Confirm the application record, classification and affected boundary with the responsible designers and AHJ. Our tenant-improvement checklist provides an applicant-facing decision tree and an illustrative office-lighting scenario; this page explains the service, inputs and handoffs.

Five-stage workflow: define, document, coordinate and hand off

The scope, evidence and responsible participants should be clear at every stage. A quote request is not payment or production acceptance, and a completed NRCC design package is not a completed installation or acceptance test.

1. 1. Intake and scope matrix

   The client/design team supplies the architectural set, application record, affected systems and available shell information. We identify the tenant boundary and new, altered, relocated or retained work. Missing equipment data or landlord assumptions are flagged rather than invented. Name the designer who can confirm each system and the party who will submit the package.

2. 2. Select the applicable documentation approach

   We assess the appropriate NRCC scope and prescriptive/performance documentation approach using the governing edition. The responsible designers establish room uses, assemblies, equipment and controls. Indoor-lighting options may use the Area Category Method where appropriate; a limited lighting project is not automatically a full-building model. Preliminary option work remains distinct from final permit output.

3. 3. Prepare the design-compliance package

   We prepare the agreed NRCC documents and supporting compliance information from the supplied design. The scope matrix connects forms to affected systems and plan references. Unresolved selections remain identified until confirmed. We coordinate the applicable declarations with responsible parties without claiming that the report preparer can sign every design, installation or testing statement.

4. 4. Designer review and drawing coordination

   The design team checks tenant areas, space uses, fixture quantities, input power, equipment identifiers and control sequences against the package. We reconcile changed assumptions and identify the controlling drawing revision. A supplier substitution or revised partition layout is reviewed for its actual effects; an earlier calculation does not approve unlimited later changes.

5. 5. Permit support and construction-stage handoff

   The applicant submits through the AHJ process and supplies complete comments if corrections arise. We scope design-document responses and identify applicable NRCI installation, NRCA acceptance and any NRCV verification handoffs. Installers and qualified testing participants perform their separate work. We do not control review queues, complete field testing by preparing forms, or guarantee issuance or occupancy approval.

Inputs that make a commercial quote useful

Send readable PDF drawings with supporting DWG/ZIP files where useful, plus a short system-by-system change list. The intake guide explains file preparation. Distinguish the proposed work area from the entire property, and provide a source for retained shell assumptions instead of relying on an unexplained old report.

• +Application date, governing edition, architectural plans, tenant boundary, conditioned/unconditioned areas and room/use descriptions.
• +Indoor-lighting schedule with fixture identifiers, quantities and input power; layout, controls, room functions and the work identified as retained, new, moved or altered.
• +Mechanical equipment, ventilation and control information from the responsible designer, including shared/base-building systems affected by the fit-out.
• +Affected envelope assemblies, storefront glazing/door information and any water-heating, outdoor/sign-lighting or covered-process scope.
• +Accepted shell documents where relevant, complete plan-check comments, prior compliance output and a dated change log for resubmittals.

Indoor lighting: clarify the method, then coordinate the controls

LTG is common lighting shorthand on drawings; the CEC’s indoor-lighting design certificate uses NRCC-LTI. Consult the current CEC forms hub and 2025 NRCC-LTI scope fields rather than copying a form number or claimed exemption from a previous project.

The Area Category Method is applicable to tenant improvements under the CEC’s 2025 manual. It depends on the actual primary-function areas, not just the tenant’s business name. Supply clear room/use areas and fixture data so the responsible designer can select the method and categories. This service page supplies no universal alteration threshold or lighting-power allowance.

Connected power and lighting controls need separate attention. A low-wattage fixture schedule does not by itself demonstrate required manual, shut-off, daylight-responsive or other applicable controls. Match the sequence to the real layout, fixture tags and systems. An LED substitution may change power and control compatibility; it is not automatically equivalent to the accepted design.

Use the CEC 2025 lighting manual for current requirements. The supplied indoor-lighting background PDF contains 2019 manual material despite its upload URL; it is not a 2025 fact sheet or a current source of thresholds. We keep this distinction explicit rather than reproducing outdated allowances.

Deliverables and who owns each handoff

The agreed design output includes a scope-to-document matrix, applicable NRCC records, coordinated assumptions and measures to reflect on the drawings. Final output is tied to the agreed plan revision. A preliminary option study is not silently promoted to final documentation while fixture selections, room uses or equipment remain unresolved.

The client supplies the project record and authorizes scope decisions. The architect and discipline designers own their designs and coordinated schedules. We prepare the scoped energy-compliance documentation from that evidence. Installers complete applicable NRCI records; qualified participants complete required NRCA acceptance or NRCV verification. The nonresidential forms overview explains these distinct families.

The CEC forms hub identifies certified Acceptance Test Technicians for applicable NRCA forms ending in -A and a different field-technician path for -F forms. Confirm the actual form and qualification rather than assuming every certificate uses one process. Current ECC terminology applies where required verification uses that program; HERS is legacy wording, not a substitute name for lighting-control acceptance testing.

What report preparation does not include

Field testing, acceptance testing, registry fees, CALGreen documentation and AHJ plan-check/permit fees are separate. We do not claim to provide mechanical/electrical design, commissioning, contractor installation certification, an ATT credential or ECC registry operation. Design-document coordination does not perform the underlying test, waive it or establish that an installed control sequence operates correctly.

Existing-building evidence also has limits. A landlord’s general assurance is not a substitute for the equipment or assembly information required by the chosen approach. If the design changes, identify the change and responsible designer before assuming an earlier report remains usable. If a required observation was missed, the qualified testing party and AHJ determine next steps; the modeler cannot create a past test result.

Published commercial pricing and revision scopes

The existing commercial menu is up to 5,000 sq ft $399; 5,001–15,000 sq ft $599; above 15,000 sq ft Custom quote. Confirm the area and documentation scope during intake rather than automatically using the whole landlord property. See Pricing for the same published schedule and exclusions; this is not a new TI-only fee menu.

City plan-check corrections caused by our modeling/report error are Free. Architectural/design revisions after the report are $75 flat. Full remodeled models or major redesigns requiring a rebuild are Custom quote via intake, not $75. Provide the prior report, reviewed drawings and change summary so those categories are not confused.

Commercial rush is +$149 for next-business-day production after complete inputs. It is not unconditional 24-hour delivery, city review acceleration or a permit guarantee. Get a Quote and upload plans to confirm the scope before production. No payment is taken by the request form.

Practical decision: a lighting-only request or a broader fit-out?

ILLUSTRATIVE ONLY: an applicant describes a project as “replace office lights,” but the drawings also create an enclosed meeting room and alter mechanical service. The useful intake question is not whether the company calls it a minor TI. It is which systems and controls the actual permit changes, what evidence exists for retained equipment, and who confirms the proposed design.

If lighting is the only affected scope, document that boundary and use the applicable approach; do not commission unrelated whole-building options by default. If multiple systems change, coordinate their documents and handoffs. The TI journal example shows fixture arithmetic without pretending it establishes a code allowance. For genuine option decisions, see energy modeling.

Respond to review comments with the actual reviewed package

Send complete numbered comments, the reviewed NRCC and drawing set, and any subsequent design changes. The plan-check correction service explains comment ownership and consistent resubmittals. Educational information is not legal advice; the AHJ determines permit requirements and local amendments. We do not invent a local ordinance, review duration or approval outcome.

Typical scope

• +Scope review to identify which NRCC documents may apply
• +Envelope, mechanical and lighting documentation coordination
• +Performance modeling where useful
• +Notes on acceptance testing that may be required (NRCA)
