Residential Title 24 energy reports

Whether you are building a new home or adding a primary suite, the Energy Code sets minimum standards for insulation, windows, HVAC, water heating, ventilation and — for new homes — solar PV. We model the project, choose the most practical compliance path, and explain any upgrades in plain language.

Quick answer

A residential Title 24 report is the energy compliance documentation for a single-family home, addition or alteration. It shows, usually on a CF1R form, that the design meets California’s Energy Code — either prescriptively or through computer performance modeling — and is submitted with the building permit application.

What’s included

  • CF1R certificate of compliance
  • Performance or prescriptive path, whichever fits best
  • Heat-pump baseline analysis under the 2025 code
  • Solar PV and battery requirement review
  • List of required field verifications
  • Plan-check revisions (see pricing)

When does a home project need Title 24 energy compliance?

New construction, additions, and alterations that change conditioned space, the envelope, or energy-using systems typically need energy compliance documentation. Small like-for-like replacements may be handled with a simpler prescriptive form.

Which code edition applies?

Permit applications submitted on or after January 1, 2026 fall under the 2025 Energy Code. Applications submitted before that date generally follow the 2022 code.

Which compliance forms are used?

Single-family projects are documented on CF1R certificates of compliance (e.g. CF1R-PRF-01 for the performance path).

What documents do I need?

  • Floor plans (existing and proposed for additions)
  • Elevations and sections
  • Window schedule
  • Site plan with north arrow
  • Roof plan
  • Mechanical / plumbing notes if available
  • Existing conditions for alterations (year built, existing HVAC, insulation)

Missing something? Order anyway — we’ll flag gaps and, where appropriate, use code-minimum assumptions with your approval.

How we prepare your report

  1. 01
    Plan & data intake

    We review your plans for completeness — floor plans, elevations, sections, window schedule and mechanical notes — and flag anything missing before modeling starts.

  2. 02
    Climate zone & scope confirmation

    We confirm the project’s climate zone from the site address using the CEC lookup, and the compliance scope (new construction, addition, alteration).

  3. 03
    Energy modeling

    The building is modeled in CEC-approved compliance software, choosing the performance or prescriptive path that best fits your design.

  4. 04
    Technical review

    Inputs are checked against the plans: areas, orientations, assemblies, fenestration, HVAC and water heating, PV and battery requirements.

  5. 05
    Delivery & revisions

    You receive the signed compliance documents as PDF, ready to print onto the plan set, with included revisions for plan-check comments.

Frequently asked questions

Performance vs prescriptive — which is better?

Prescriptive compliance follows a fixed checklist. Performance modeling lets you trade efficiency between components, which often avoids costly upgrades. We pick the path that fits your design.

Is the price based on square footage?

Yes. Residential reports include a base area; larger homes add a per-square-foot amount. Use the estimator for an instant figure.

Can you help if plan check rejected my report?

Yes — send the plan-check comments with your order and we will address them.
