Title 24 Compliance Checklist for Contractors — A Field-Ready Guide to Passing Permits and Inspections in California

If you’re a general contractor, HVAC contractor, insulation contractor, builder, or project manager working in California, Title 24 energy compliance is not just a permit form—it’s a coordination requirement that touches your schedule, your subcontractors, your inspections, and your closeout. This Title 24 Compliance Checklist for Contractors is designed to help you avoid the most common jobsite pitfalls: mismatches between plans and installed equipment, missing documentation at inspection, and last-minute changes that trigger compliance revisions and resubmittals.

Contractors are often the “last mile” between approved paperwork and real installations. That means you can do everything right in the field and still get delayed if a window substitution isn’t documented, if the HVAC model number doesn’t match the energy report, or if the job is missing required verification paperwork when the inspector shows up. The goal of this checklist is simple: keep your project permit-ready and inspection-ready with fewer surprises.

If you’re facing a tight schedule or need a fast compliance revision, call (626) 365-1518.

Step 1: Confirm the Project Scope That Triggers Title 24

Before mobilizing trades, confirm whether the permit scope requires energy documentation and field verification. Many projects do, including:

• New construction (residential and many commercial projects)
• ADUs and junior ADUs
• Additions increasing conditioned floor area
• Garage conversions and major remodels affecting envelope or mechanical scope
• Commercial tenant improvements (lighting, controls, mechanical upgrades)
• HVAC replacements under permitted scope (depending on the jurisdiction and scope)

Contractor tip: Ask for the approved Title 24 package and review it early—don’t wait until the first inspection.

Step 2: Get the Approved Title 24 Documents Before You Start

One of the biggest causes of failed inspections is not having the approved compliance forms on hand—especially when an inspector wants to confirm model numbers, ventilation assumptions, or envelope measures.

As part of your Title 24 Compliance Checklist for Contractors, request:

• The approved Title 24 compliance forms (project-specific)
• Any plan-check correction responses tied to energy compliance
• Final permit-intent plan set (architectural + mechanical)
• Window schedule with U-factor and SHGC values
• Mechanical schedule listing HVAC system type and efficiencies

Contractor tip: Keep a digital copy on the job and a printed set available when inspections are scheduled.

Step 3: Lock Product Selections That Affect Compliance

Compliance documentation is only as accurate as the specifications it’s based on. If products change after approval, you may need a revised Title 24 report.

Key “don’t swap without checking” items include:

• Windows: U-factor and SHGC must match the approved assumptions.
• HVAC equipment: efficiency ratings and system types must match the compliance package.
• Water heaters: type and efficiency assumptions must align.
• Insulation: R-values and assembly types must match plans.
• Solar (if applicable): system size and assumptions must match documentation.

Contractor tip: Substitution requests should be reviewed for compliance impact before ordering or installation.

Step 4: Window Installation Checklist (Avoid Documentation Mismatch)

Windows are a top plan-check and inspection trigger. Contractors should:

• Verify window labels and performance documentation (U-factor/SHGC) match the approved schedule
• Confirm window sizes match the plan set (especially egress and glazed area)
• Document any substitutions immediately and request compliance updates if needed
• Avoid mixing product lines without confirming performance ratings

Contractor tip: Keep manufacturer cut sheets or performance documentation available for inspection when required.

Step 5: HVAC Installation Checklist (Model Numbers Matter)

HVAC mismatches frequently cause failed inspections because the energy documents often specify efficiencies tied to certain model numbers.

HVAC checklist items:

• Confirm the installed system type matches approved documentation (ducted vs ductless, heat pump vs other)
• Verify model numbers match planned efficiency ratings
• Coordinate ventilation requirements and controls (as applicable)
• Confirm thermostat/control requirements align with documentation
• Schedule testing/verification steps early if required

Contractor tip: If equipment availability forces a change, request a compliance revision before installation whenever possible.

Step 6: Insulation and Envelope Checklist

Insulation quality and correct installation can affect compliance verification. Ensure:

• Wall insulation matches specified R-values and assembly type
• Ceiling/roof insulation matches specified R-values
• Floor insulation is installed where required
• Insulation is not compressed or missing at key locations
• Envelope details match the approved plan set

Contractor tip: Don’t wait until drywall inspection to discover missing insulation measures.

Step 7: Commercial Lighting and Controls Checklist (If Applicable)

For tenant improvements and many commercial projects, lighting and control requirements are common delay points.

Commercial checklist items:

• Confirm fixture schedules match energy documentation
• Verify lighting power density (LPD) is within allowable limits
• Install required controls (occupancy sensors, time controls, daylighting controls where applicable)
• Ensure control zones match the design intent and plan notes
• Clarify TI scope boundaries to avoid over-documenting or under-documenting

Contractor tip: Many “failed inspections” are really control/commissioning issues, not fixture quality issues.

Step 8: Manage Revisions Like a Pro (Avoid Resubmittals)

Change orders happen. The contractor’s job is to keep changes from breaking compliance.

If any of these change, notify the Title 24 consultant immediately:

• Window manufacturer/series changes
• HVAC system substitutions
• Insulation assembly changes
• Solar system size changes (if included)
• Scope changes affecting conditioned area

Contractor tip: A quick compliance revision now is faster and cheaper than a failed final inspection later.

Step 9: Inspection Day Checklist

Before inspections (rough, insulation, mechanical, final), confirm:

• Approved Title 24 documentation is available onsite
• Installed systems match documentation (model numbers, efficiency ratings)
• Required controls are installed and functional
• Any verification paperwork is ready if required
• Trade partners are aligned on what the inspector will review

Contractor tip: Many delays happen because the inspector can’t verify something quickly. Make verification easy.

Step 10: Closeout and Recordkeeping

At closeout, the goal is to leave a clean compliance trail. Keep:

• Final approved Title 24 documentation
• Any revised forms issued during construction
• Equipment submittals and cut sheets (as needed)
• Inspection sign-offs tied to energy requirements

This protects you if questions come up later and helps future scope changes stay clean.
