1 zone

One zone is included. Each additional zone is +$100. An addition needs two (the existing house and the new work), and a project with more than one building needs one per building.

Options

ECC/HERS and QII are field verification. The fee depends on the rater and the measure list, so both are quoted rather than published.

    Credentials & registries

    Certified, and registered where it counts.

    What each credential means CABEC · ICC · CHEERS
    CABEC, California Association of Building Energy Consultants
    CABEC Certified Energy Analyst (CEA)

    The CEA is the credential California's energy-code trade is measured by, issued by the California Association of Building Energy Consultants and earned by examination. Plenty of people produce Title 24 forms; far fewer have been tested on the standards behind them.

    ICC Certified: CALGreen Inspector / Plans Examiner

    CALGreen is Title 24 Part 11, the green building code that shares your permit with the Part 6 energy code. Certified to examine those plans and inspect the work, so the second code doesn't ambush you at plan check.

    Why choose us

    Your report is only as good as the model behind it

    A Title 24 report arrives looking like paperwork. Behind it is building physics. Heat moving through assemblies, solar gain changing with orientation, duct losses and water heating loads, with a compliance form stapled to the front. The credentials behind your report decide how much trouble it saves you later.

    THE HARD END OF THE CODE

    Commercial work sets the standard we use everywhere

    We do NRCC energy compliance across the full range: offices, retail, restaurants, gas stations, hotels and motels, apartments and multifamily. Envelope, mechanical, lighting and acceptance testing, defended to project engineers who check the numbers. Those habits carry into every ADU and addition we touch. Almost no residential practice has that background; almost no commercial specialist takes small work.

    Saving $40 on the report can cost thousands on the build

    Where a cheap report costs you money

    Why that happens 2 min

    When a compliance model is rushed, the easiest way to make it pass is to add requirements to your building. Thicker insulation than the framing needs, a bigger heat pump than the design called for, field tests that careful modeling would have removed. None of that shows up on the report. All of it shows up on the invoice from your framer, your HVAC contractor and your rater.

    The price gap between energy consultants is usually $30 to $50. The construction gap from an over-specified report runs into the thousands. We model the building as you drew it and look for the cheapest way to make it comply. That is the part of this job with real money in it.

    What that means in practice: plan-check corrections are included in every fee, for the life of the project. We can offer that because reports built this way rarely come back.
    Field verification

    The part that puts someone on your site.

    Most compliance work happens on paper. Two things do not, and both are decided by your CF1R long before anyone turns up with a duct blaster.

    ECC / HERS RATING

    Field verification and registration

    From January 1, 2026 this runs under the ECC program, Energy Code Compliance. It was called HERS before that, and both names are still in circulation. Same tests, same forms.

    What gets tested 4 measures
    • Duct leakage, tested against a target
    • Refrigerant charge, on heat pumps in every climate zone under the 2025 code
    • Airflow and fan watt draw
    • Envelope air leakage, where the model claims a tighter build

    We produce the CF1R, register it, chase the contractor's CF2R forms, schedule an independent rater and confirm the CF3R lands before you need the sign-off.

    QII

    Quality Insulation Installation

    A compliance credit for insulation that is actually installed properly, with no gaps, compression or missed cavities. The model can take credit for it, and in a hot or cold climate zone that credit is often what buys the margin.

    It has a deadline that expires quietly. QII is inspected twice, once during framing and again before drywall goes up. Miss the framing visit and the credit is gone for good, which means the model no longer complies and something else has to pay for it.

    If your CF1R claims QII, it gets scheduled at modeling stage rather than discovered on site. If it does not need to claim it, we say so.

    Price a project with QII →
    Which measures need verifying is a design decision, not a fixed list. It is set by what your compliance model takes credit for. Claim a verified measure and somebody has to come out and test it. We will tell you which ones the margin actually depends on and which you could drop, before anyone is committed.
    How a job runs

    Send plans Monday.
    Get forms Wednesday.

    No intake call and no portal to sign up for. A PDF of the plan set is enough to start, and usually enough to finish.

    What we actually need: the architectural plan set as a PDF, with floor plans, elevations, and the window and door schedules. If you have a Bluebeam takeoff already, send it; if you don't, we'll do it.

    Climate Zone

    Enter a city or ZIP code, or click a node on the map. You'll get the zone, what drives the design there, and where projects lose margin.

    Zone assignment is set by the California Energy Commission and follows ZIP code boundaries. A handful of cities straddle two zones. If yours is one of them we will confirm it from the address for free.

    Questions people ask before they hire us

    No sales language. If the answer is "you don't need us for that", that's the answer you'll get.

    All questions →
    How much does a Title 24 report cost?

    An ADU, JADU or standard garage conversion starts at $200 on the prescriptive path. Additions and remodels start at $300, new homes at $300. Each zone beyond the first adds $100.

    Commercial NRCC work and multifamily are quoted on a call, because scope there is driven by building type, unit count and system layout rather than by floor area. For everything else, the calculator at the top of this page gives you the real number without you having to contact anyone first.

    Which code applies, 2022 or 2025?

    The 2025 Energy Code took effect on January 1, 2026 and applies to every permit application submitted on or after that date. If your permit application went in before then, you stay under the 2022 code. When a project has been sitting for a while this is the first thing worth checking, because it changes the requirements materially.

    How much does an ECC / HERS report cost?

    This is the one thing on the site that isn't on the calculator. ECC (formerly HERS) field verification is quoted per project, because the cost is driven by the measures your CF1R calls for, the number of dwelling units and the number of site visits, rather than by floor area.

    Call (909) 914-0305 for a quote. With the CF1R in front of you it takes about two minutes. Registry and rater coordination is quoted on the same call.

    What's the difference between a HERS rater and an ECC rater?

    They're the same role under a new name. With the 2025 code the Energy Commission renamed HERS (Home Energy Rating System) verification to ECC (Energy Code Compliance) verification. Same field tests, same CF2R and CF3R registration process. Only the acronym on the paperwork changed. Anyone telling you it's a new requirement is mistaken.

    Do I need a Title 24 report for an ADU?

    Yes. Any new conditioned floor area in California needs a Part 6 compliance report with the permit application: detached ADUs, attached ADUs, garage conversions, JADUs, all of it. Most ADUs are exempt from the solar PV requirement, but envelope, HVAC and water heating rules still apply in full.

    What if the city rejects the report?

    Corrections are included, for as long as the project takes, at no extra cost. If a plan checker comes back with a comment on the energy documents, fixing it is part of the original fee. We'd rather absorb that than have you price in risk.

    Do you work in my city?

    All 58 California counties and all 16 climate zones. The work is done from the plan set, so where the project sits doesn't limit anything. Crescent City to El Centro, coastal to desert.
