Title 24 Energy Compliance in Santa Clarita, CA

Title 24 Energy Compliance in Santa Clarita, CA

Title 24 energy compliance is a California-mandated calculation report that every new ADU permit set must include before the city will issue a building permit, and our ADU Design & Permitting services handle this from the start. In Santa Clarita, that means a certified CF1R compliance form and supporting energy model demonstrating your ADU meets the 2022 California Energy Code – the version currently enforced by the City of Santa Clarita Building and Safety Division. Without it, your permit application is incomplete on arrival.

At Ellery ADU Studio, the Title 24 report is not a line item we outsource and forget. It is drafted as part of the permit set – the same document package that carries our ADU Design & Permitting in Santa Clarita scope – so the insulation values, window U-factors, and mechanical specs written into the energy model match the construction drawings exactly. Discrepancies between the energy report and the plans are one of the most common reasons Santa Clarita ADU permits stall at plan check. We close that gap before submission.

When You Need Title 24 Energy Compliance

• New detached ADU on a Santa Clarita lot. Any standalone unit – whether stick-framed, or a prefab system like Cover or Dvele coordinated through our single-contract model – requires a full CF1R compliance report before the city issues a permit.
• Garage conversion in Saugus, Valencia, or Canyon Country. Converting an attached or detached garage to habitable space triggers a Title 24 calculation for the new conditioned area. The existing structure’s envelope often needs upgrades – insulation, glazing, or both – to pass.
• Junior ADU created from interior space. Even a JADU carved out of existing square footage requires an energy compliance report when the scope includes HVAC changes, new windows, or a new exterior door.
• Permit resubmission after plan-check correction. If a previous designer submitted an energy report that did not match the architectural drawings, Santa Clarita Building and Safety will issue a correction notice. We regularly step into projects at this stage to reconcile the two documents and resubmit.
• Solar mandate compliance verification. California’s 2022 Energy Code requires most new ADUs to include a solar photovoltaic system. The Title 24 model must reflect the correct system size; under-specifying the PV array is a common error that triggers a second plan-check round.
• Prefab or modular ADU installation. Factory-built units from brands like Dvele or Mighty Buildings arrive with their own thermal performance data, but the on-site foundation, utility connections, and any site-built elements still need to be wrapped into a site-specific Title 24 report for the Santa Clarita permit set.

Our Title 24 Energy Compliance Process

1. Site Assessment and Envelope Review

   We start with the existing conditions: lot orientation, shading from neighboring structures or the Santa Clarita hillside topography, wall assembly, roof pitch, and any existing mechanical equipment that will carry over. In the hotter inland climate of Santa Clarita – where summer cooling loads in Newhall or Stevenson Ranch regularly push past what the coastal baseline assumes – orientation and shading analysis can shift the compliance path and the required solar array size by a meaningful margin. We document what we find with a photo record; you receive that record, not just a summary.

2. Energy Model Development

   Using California Energy Commission-approved software (currently EnergyPro), we build a room-by-room energy model that reflects the actual wall assemblies, window-to-floor-area ratios, mechanical system efficiency ratings, and the solar PV specification. We do not use generic default values where project-specific data is available; generic defaults tend to result in over-specified PV systems or insulation upgrades that add cost without regulatory benefit.

3. Coordination with Architectural Drawings

   Every value in the Title 24 report – R-values, U-factors, SHGC ratings, duct insulation levels – is cross-referenced against the architectural and mechanical sheets before we finalize either document. This is the step where most permit sets break down when the designer and the energy consultant work separately. Because our ADU Design & Blueprints process keeps both under the same contract, the coordination happens internally rather than through email chains between separate firms.

4. CF1R Form Completion and Wet-Stamp

   The CF1R is the registration document that goes into the permit set. We complete it through the CHEERS registry (California Home Energy Efficiency Rating System), which is the Santa Clarita Building and Safety Division’s accepted compliance tracking platform. The registered CF1R certificate number is included in the permit package we submit on your behalf.

5. Plan-Check Response

   If Santa Clarita Building and Safety issues a correction notice related to the energy compliance documentation – whether that is a missing mandatory measure, a PV sizing question, or a discrepancy with a mechanical schedule – we respond to that correction as part of the scope. There is no separate hourly fee for plan-check responses; the written price you received at the start covers it.

6. CF2R and CF3R Field Verification

   Title 24 compliance does not end at permit issuance. The CF2R (installation certificate, completed by the contractor) and CF3R (field verification, completed by a HERS rater) are required before final inspection. Because Ellery operates as a design-build studio, the same team that produced the energy model can confirm that insulation installation, duct testing, and PV commissioning match what the CF1R promised. The 365-Day Done Right Promise covers this: if the finished ADU is not built to the permitted drawings and the energy compliance documentation, we make it right – in writing, before the project starts.

Title 24 Energy Compliance Pricing in Santa Clarita

Title 24 compliance is priced as part of the full ADU permit set, not as a standalone line item – because separating the energy model from the drawings that must match it is how errors happen. That said, here is what the energy compliance component typically represents within an Ellery permit set for Santa Clarita projects:

Factors that push a project toward the upper end of these ranges include: complex roof geometry that requires additional solar modeling, split mechanical systems serving multiple zones, existing conditions that require envelope upgrades to pass compliance, and projects in the hotter micro-climates of Canyon Country or Newhall where the cooling load calculations are more demanding than Santa Clarita’s cooler Stevenson Ranch elevations. See How Much Does ADU Design & Permitting Cost? (2026 Price Guide) - Santa Clarita, CA for typical pricing ranges.

Every price is written before any work starts. That is Haven Standard Clause 1, not a marketing line. You will receive a written scope and fixed price at the proposal stage; the words “call for a quote” do not appear on this site because we do not operate that way. If you already have a written estimate from another firm, we offer a free second opinion on it – call (747) 294-4817 and a live person will set that up.

What Affects Your Santa Clarita ADU’s Title 24 Outcome

Santa Clarita sits in California Climate Zone 9, which covers most of the Santa Clarita Valley. Zone 9 carries a higher cooling load than coastal Climate Zone 6, and the energy model must reflect that. In practical terms, this means:

• Window specifications matter more here than in many other parts of Los Angeles County. A low solar heat gain coefficient (SHGC) is not optional on south- and west-facing glazing in a Newhall or Valencia ADU – it is the difference between passing and failing the model.
• The mandatory solar PV requirement under the 2022 Energy Code applies to most new ADUs in Santa Clarita. The required system size is calculated from the conditioned floor area; a 650-square-foot detached ADU in Saugus will typically require a 1.5 to 2.5 kW system at minimum, though the exact calculation depends on the orientation and available roof area.
• Duct insulation levels for mini-split or ducted HVAC systems must meet the code minimum, and duct leakage must be tested and documented in the CF2R. For prefab units like a Mighty Buildings installation where the factory handles the envelope but the site team handles the mechanical connections, this coordination step is where projects can slip if the two parties are not working from the same document set.
• Attic insulation is frequently the most cost-effective compliance lever on a Santa Clarita garage conversion. Many Saugus and Canyon Country garages have R-11 batts at best; upgrading to R-30 dense-pack in the ceiling plane can shift the energy model enough to reduce the required PV array size and lower total project cost.

FAQs – Title 24 Energy Compliance in Santa Clarita

Is Title 24 compliance required for every ADU in Santa Clarita?

Yes – every ADU permit in Santa Clarita requires a completed CF1R energy compliance report registered with CHEERS before the city will issue a building permit. This applies to new detached ADUs, garage conversions, and junior ADUs that involve HVAC, new windows, or changes to the building envelope. The only exception is an interior conversion with no mechanical changes and no alterations to the thermal envelope, and in practice those projects are rare. Call (747) 294-4817 if you want to confirm which compliance path your specific project requires.

Can I use a Title 24 report from a previous designer if I am switching to Ellery?

Sometimes, but usually not without revision. If the existing report was prepared to match a different set of architectural drawings, any discrepancy between that report and our permit set will generate a plan-check correction from Santa Clarita Building and Safety. We review the existing report as part of our free second opinion service. If it can be adopted with minor amendments, we will say so and price accordingly. If it needs to be rebuilt from scratch, we will explain exactly why and give you a written price before touching anything. Call (747) 294-4817 to bring the existing documentation in for review.

How long does Title 24 compliance add to the Santa Clarita ADU permit timeline?

When the energy compliance documentation is prepared alongside the architectural drawings – as it is in an Ellery permit set – it does not add time to the schedule. The CF1R is registered and included in the initial permit submission. Problems arise when the energy report is ordered after the drawings are complete, because mismatches then require revision cycles before submission. The Santa Clarita Building and Safety Division’s current ADU plan-check queue runs four to eight weeks for an initial review; an incomplete or mismatched energy report can add one to three weeks of correction time to that cycle.

What happens if my ADU fails the Title 24 energy inspection at final?

Failing the CF3R field verification – the final HERS inspection – means the city will not issue a certificate of occupancy. The most common causes are duct leakage above the permitted threshold, insulation that was installed at the wrong R-value, or a solar system that was not commissioned or sized to match the CF1R. Under Ellery’s 365-Day Done Right Promise, if the finished ADU is not built to the permitted drawings and the energy documentation, we make it right. That commitment is in writing before the project starts, not offered after something goes wrong. Call (747) 294-4817 to understand exactly what that promise covers on your project.

Key Takeaways

• Title 24 compliance is required for every Santa Clarita ADU permit – new detached, garage conversion, and most interior conversions.
• Santa Clarita falls in Climate Zone 9, which sets higher cooling-load requirements than coastal Los Angeles. Window SHGC ratings and solar PV sizing are the two variables most likely to affect your compliance path and your construction budget.
• The energy compliance report must match the architectural drawings exactly. Preparing them together – as Ellery does under a single contract – eliminates the most common cause of plan-check delays.
• Pricing for the energy compliance component of an Ellery permit set typically runs $800 to $3,500 depending on project size and complexity, and is always provided in writing before work starts.
• The 365-Day Done Right Promise and Haven Standard Clause 1 (written price before work starts) apply to every project, including Title 24 compliance work.
• A free second opinion is available on any written estimate you have already received. Call (747) 294-4817.
