What our Title 24 compliance service includes

Every California building permit that affects energy use – new homes, ADUs, additions, HVAC changes, lighting in commercial spaces – must show compliance with the California Energy Code. Projects can comply prescriptively (meeting each listed requirement) or through the performance approach, where software shows the design uses no more energy than the standard design. The performance route usually gives more design flexibility.

We model the building in CEC-approved software, test options when it does not pass (better windows, insulation, heat pump water heaters, PV sizing), and prepare the compliance forms and the energy notes for the plans. The 2025 Energy Code applies to permit applications from January 1, 2026; projects submitted earlier may still fall under the 2022 code.

Title 24 work is usually paired with HVAC load calculations and residential drafting. Rooftop PV requirements link to solar design.

Title 24 Compliance Services standards in the USA, UK, Canada and Australia

We set up every project on the standard of the country where it will be built or manufactured. These are the references we work to most often:

CountryStandards and codes we draft Title 24 compliance services to
USACalifornia Code of Regulations Title 24, Part 6 (Energy Code) – 2022 edition and the 2025 edition effective January 1, 2026; Part 11 CALGreen mandatory measures
UKNot applicable – UK projects use Building Regulations Part L with SAP/SBEM (we can draft Part L details)
CanadaNot applicable – Canadian projects use NECB 2020 or provincial energy codes (e.g. OBC SB-12)
AustraliaNot applicable – Australian projects use NCC Section J and NatHERS ratings

Engineering responsibility: we prepare drawings, models and calculations as a drafting and design-support team. Where the law in your state, province or council requires it, the final design must be reviewed, signed and sealed by the licensed engineer or architect of record for the project. We work to their markups and do not stamp drawings ourselves.

How our Title 24 compliance services process works

  1. 1
    Send your files

    Upload sketches, PDFs, markups, photos, scans or a model through the quote form. Tell us the standard (US, UK, Canada or Australia) and the deadline.

  2. 2
    Fixed quote in hours

    We review the scope and reply with a fixed price, the deliverables list and a delivery date. Nothing starts until you approve it.

  3. 3
    Drafting & modeling

    Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.

  4. 4
    QA check

    A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.

  5. 5
    Delivery & revisions

    You receive native files plus PDFs. Comments come back as markups and we revise them quickly until the set matches the brief.

Turnaround and pricing

Residential Title 24 reports are typically delivered in 2–4 business days; commercial reports are quoted by scope. Every job is priced as a fixed quote after we review your files, so you know the cost and the delivery date before work starts. See how our pricing works, or send your files through the quote form for a quick estimate.

Title 24 Compliance Services projects often need HVAC load calculation services, residential drafting services and solar design services as well. You can order them together on one quote, or browse every option in our MEP engineering services.

Frequently asked questions

What is Title 24 compliance?

It is showing that a California building project meets the state's Building Energy Efficiency Standards (Title 24, Part 6), using prescriptive requirements or a performance calculation.

What is a CF1R?

The CF1R is the residential Certificate of Compliance – the form that documents how a home or addition complies with the Energy Code. Nonresidential projects use NRCC forms.

Which Title 24 edition applies?

The 2025 Energy Code applies to permit applications submitted on or after January 1, 2026; earlier applications generally follow the 2022 code. Your building department confirms which applies.

Do ADUs need Title 24 calculations?

Yes. New ADUs, and conversions that add conditioned space, need Title 24 energy compliance documentation.

What is HERS verification?

Some measures (such as duct leakage or refrigerant charge) must be field-tested by a certified HERS rater. The compliance documents list which measures need verification.
