Title 24 Energy Compliance in Sacramento, CA
Title 24 energy compliance in Sacramento means your ADU, garage conversion, or home addition meets California’s mandatory building energy efficiency standards before you can pull a final permit. Most Sacramento homeowners first hear about Title 24 when their city building department flags their plans during plan check. At Lodgewick ADU Sacramento, we handle Title 24 documentation, energy modeling, and field verification as a standard part of every ADU Design & Permitting project, so the compliance work never becomes a surprise line item or a permit holdup. Call us at (279) 256-1973 if you are mid-project and just found out you need Title 24 paperwork, and we will tell you exactly what it takes to get your permit moving again.
Here is the direct answer most homeowners are searching for: Title 24 compliance for a typical Sacramento ADU project costs between $1,400 and $3,800 when handled as part of a full design and permitting package, and it is almost always a required step, not an optional one. The exact number depends on whether you are building a detached ADU, a garage conversion, or an addition, plus your HVAC choices, window types, and lighting plan. You are reading this page because you want a real number and a straight explanation, so here it is: the work involves two main parts, energy modeling documentation and on-site field verification, and both follow a specific sequence that we will walk through below.
We are the ADU company of the Kingswell family, building accessory dwelling units across Sacramento since 2010. Every Title 24 compliance job we take on operates under The Kingswell Guarantee: a written price before any work starts, a defined arrival window, a clean job site, and a written guarantee on every project. If something is not right, we come back and make it right under our 365-Day Done Right Promise. That commitment is in writing before we ever run an energy model.
Key Takeaways
- Title 24 compliance is mandatory for nearly every ADU, garage conversion, and addition in Sacramento; you cannot pass final inspection without it.
- Typical Sacramento Title 24 compliance costs run $1,400 to $3,800 when bundled with design and permitting.
- The process has two phases: energy modeling and documentation (CalCERTs), then on-site field verification after construction.
- Plan check delays are common when Title 24 documentation is missing or filled out wrong; we fix that before you get stuck.
- Lodgewick ADU Sacramento includes Title 24 compliance as a line item in every written project quote. No surprises, no change orders at the door.
When You Need Title 24 Energy Compliance
If you are building or converting anything that adds conditioned living space in Sacramento, you almost certainly need Title 24 compliance. The California Energy Commission wrote the current Title 24 standards to cut energy use in new and altered buildings, and local building departments in Sacramento County, the City of Sacramento, Roseville, Elk Grove, and Folsom all enforce them during plan check. If any of the following sounds like your situation, you need this work done:
- You are planning or building an ADU. Every detached ADU, attached ADU, and JADU (junior accessory dwelling unit, a smaller unit within an existing home) requires Title 24 energy documentation as part of the permit application package.
- You are converting a garage into living space. Garage conversions in Sacramento neighborhoods like Tahoe Park, East Sacramento, and Land Park trigger Title 24 requirements because unconditioned space becomes conditioned space. The existing garage shell rarely meets current insulation, window, or HVAC efficiency standards on its own, so the paperwork has to show how you will close the gap.
- Your plan check came back with comments. If the City of Sacramento or Sacramento County building department kicked your plans back citing missing CF-1R, CF-2R, or CalCERTs documentation, that is Title 24. This is the most common reason homeowner permit applications stall for weeks.
- You are adding a room or expanding a floor plan. Any home addition that changes the building envelope, adds windows, or extends HVAC ductwork needs new Title 24 documentation, even if the original house was built before modern energy codes.
- You are replacing windows, HVAC equipment, or insulation as part of a larger build. Title 24 applies to the whole project when the permit touches multiple systems. A window swap in a converted ADU can affect the overall energy model, which is why we review everything together.
- You bought a home with an unpermitted conversion. Sacramento homeowners who inherit an unpermitted garage conversion or ADU often need to bring the space into Title 24 compliance during the legalization process. This is more complex than new construction compliance because the energy model has to reflect what already exists in the walls and attic, not just what the plans show.
Our Title 24 Energy Compliance Process
We keep Title 24 work structured and predictable because we have seen what happens when it is not. Homeowners who try to handle this themselves usually discover that the CalCERTs registry system, the CF-1R and CF-2R forms, and the field verification requirements are not intuitive, and a single missed field verification fails the entire compliance record. Our process eliminates the guesswork:
- Project review and scope confirmation. We start with the project documents: architectural plans, HVAC specs, window schedules, lighting layout, and water heating details. If you are mid-project, we also review any plan check comments from the building department to see what triggered the Title 24 requirement. We give you a written price before any compliance work starts, per The Kingswell Guarantee.
- Energy modeling and documentation. Using approved California Energy Commission software, we build a compliance model for your specific project. We run your proposed design against the Title 24 performance standards and generate the CF-1R certificate (the design-phase compliance document) along with the required CalCERTs registration. If the model shows a shortfall, we adjust the plans: higher-efficiency windows, better attic insulation, a heat pump water heater, or improved duct sealing. We hand you the corrected documentation ready for plan check submittal.
- Permit coordination. We work with the City of Sacramento, Sacramento County, and surrounding jurisdiction plan checkers to get your Title 24 documentation accepted. We respond to any additional comments directly, usually within one to two business days. Because we work with prefab ADU manufacturers including Abodu and Cover, we know the prescriptive packages their factory builds meet, which speeds plan check through faster than a custom-spec submission.
- Construction-phase verification scheduling. Once your build or conversion is underway, we schedule the required HERS (Home Energy Rating System) field verifications at the right milestones. These checks cannot happen too early or too late, or the rater has to come back, which costs you another trip charge. We build the verification schedule into the construction timeline so the inspector, the HERS rater, and your contractor are never waiting on one another.
- Field verification and testing. The HERS rater tests what actually got built: duct leakage, airflow, insulation installation quality, window performance, and water heating efficiency. If something fails, we tell you the exact correction needed, the cost to fix it, and when we can get it resolved. We do not leave a failed verification for you to figure out.
- Final CF-2R and compliance closeout. After all verifications pass, we file the CF-2R compliance certificate and close out the CalCERTs record. Your building department receives everything they need to sign off on final inspection. You get a complete copy of your Title 24 documentation for your records, which matters if you ever sell the home or pull future permits.
Title 24 Energy Compliance Pricing in Sacramento
Here is an honest look at what Title 24 compliance costs in Sacramento. We give written prices, which means the number you see is the number you pay. No price changes at the door, no re-quotes when the inspector shows up. Here are the ranges we see across Sacramento County in 2026:
| Project Type | Typical Sacramento Title 24 Cost Range | What It Includes |
|---|---|---|
| Detached ADU (new build, under 800 sq ft) | $1,400 – $2,200 | Energy modeling, CF-1R documentation, CalCERTs registration, HERS verification coordination |
| Detached ADU (new build, 800 – 1,200 sq ft) | $1,800 – $2,800 | Full compliance modeling, documentation, field verification scheduling and closeout |
| Garage conversion (standard two-car garage) | $1,600 – $2,600 | Compliance modeling for converted envelope, documentation, HERS field verification |
| JADU (junior accessory dwelling unit) | $1,200 – $1,900 | Simplified compliance documentation, CalCERTs registration, verification coordination |
| Home addition (300 – 600 sq ft) | $1,500 – $2,500 | Whole-house envelope modeling, documentation, verification scheduling |
| Unpermitted conversion legalization | $2,200 – $3,800 | Existing-conditions compliance modeling, gap analysis, documentation, field verification, correction plan |
| Plan check correction only (we did not design the project) | $400 – $900 | Review of existing documentation, corrections, resubmission support |
Three things move these numbers. First, the complexity of your mechanical system: a mini-split with electric resistance backup in an old garage shell requires more design work than a simple new ADU with a single heat pump. Second, square footage and window area: larger envelopes with more glazing need more detailed modeling. Third, whether the building department is asking for prescriptive compliance or performance compliance. Performance compliance gives you more design flexibility but takes longer to document, which shows up in the price.
When you call us for a quote, we will ask for your project address, your plans if you have them, and what stage you are at. We can usually give you a written number within one business day. If your project is already in plan check and the building department is waiting on Title 24 documentation, tell us when you call. We prioritize those files because every day of plan check delay costs you construction time.
We also work directly with established prefab manufacturers including Abodu, Cover, and Dvele. Their factory-built panels and modules arrive with consistent insulation and window packages, which often makes Title 24 modeling faster and less expensive than a stick-built equivalent. If you are considering a prefab ADU, we can tell you which manufacturers have already cleared Sacramento-area permitting hurdles and what their Title 24 documentation looks like before you commit to a purchase.
Why Sacramento Homeowners Choose Lodgewick for Title 24 Work
Title 24 compliance only matters when it is done correctly and on time. We have watched homeowners lose three weeks of construction weather while a plan checker waited on a corrected CF-1R that somebody forgot to file. That does not happen on our projects, and here is why.
Every Lodgewick project follows The Kingswell Way: we say the price before the work, show up in the window we give, leave the place cleaner than we found it, put the guarantee in writing, and come back if anything fails within the 365-Day Done Right Promise period. The 365-Day Done Right Promise is specific: if the Title 24 documentation or any field verification work is not right, we come back and fix it at no charge. That is a written commitment, not a verbal one. A free return visit if the work fails within the guarantee period. Those are the terms in black and white on every project.
You also get background-checked, uniformed technicians on your property for field verification visits, so you always know who is there and why. And when you call us at (279) 256-1973, a live person answers. That matters when you have a plan check deadline or a HERS rater waiting on your call. No voicemail loops, no chatbots, no “we will get back to you within two business days.”
Russ Delmar leads Lodgewick ADU Sacramento and has worked through Sacramento’s Title 24 requirements with homeowners across the region since 2010. A lodge, by the way, is a small house on a larger property. That is exactly what an ADU is, and Title 24 compliance is the gate you pass through before that small house becomes a legal, permitted living space.
FAQs – Title 24 Energy Compliance
How much does Title 24 compliance cost in Sacramento?
Title 24 compliance in Sacramento typically costs $1,400 to $3,800 depending on project type, square footage, and mechanical system complexity. A standard detached ADU under 800 square feet usually lands between $1,400 and $2,200, while legalizing an unpermitted conversion with existing-conditions modeling can reach $3,800. Call (279) 256-1973 for a written quote, and we will give you an exact number within one business day.
Can you handle Title 24 compliance after my plans were already submitted?
Yes, and that is one of the most common calls we get. If the City of Sacramento or Sacramento County building department sent your plans back with Title 24 comments, we review the existing documentation, correct the CF-1R or CalCERTs filing, and resubmit. Plan check correction work runs $400 to $900. We prioritize active plan check files because every day your permit is stalled is a day of construction weather lost.
What happens if my project fails HERS field verification?
If your build fails field verification, we identify the specific issue, quote the correction in writing, and coordinate the fix with your contractor or our own team. Common failures in Sacramento include duct leakage above the allowed maximum, missing insulation in hard-to-reach attic corners, and improperly sealed window openings. Under the 365-Day Done Right Promise, if our documentation or verification work is found to be incorrect, we return and make it right at no charge.
Is Title 24 the same thing as getting a HERS rating?
No. Title 24 compliance uses HERS raters to perform required field verifications, but the HERS rating itself is a separate scoring system for whole-home energy efficiency. Title 24 compliance requires the CF-1R design certificate, the CF-2R installation certificate, and CalCERTs registration, regardless of whether you choose to get a full HERS rating. We handle the Title 24 paperwork and coordinate the required HERS verifications as part of the compliance package.
Do prefab ADUs from Abodu or Cover still need Title 24 compliance?
Yes. Prefab ADUs from Abodu, Cover, Dvele, and other manufacturers still require Title 24 documentation and field verification for the Sacramento-specific site conditions. The factory-built shell and systems make the documentation cleaner, because the manufacturers pre-test window packages and often provide the necessary HERS inputs. But the site-specific pieces, including foundation insulation details, duct connections, and water heating configuration, still need local compliance work. We handle that integration.
