Title 24 Energy Compliance in North Hollywood, CA
Title 24 energy compliance is a mandatory calculation set that California requires for every new ADU and garage conversion before the city will issue a building permit. In North Hollywood, the Los Angeles Department of Building and Safety reviews these reports as part of the permit submittal - no report, no permit, no project. At Ellery ADU Studio, ADU Design & Permitting services build Title 24 compliance into the permit set from day one, not retrofitted at the end when changing something costs money.
If you’re planning an ADU in North Hollywood and the permitting process feels like a maze, you’re not alone. Our ADU Design & Permitting in North Hollywood service covers the full scope, and Title 24 is one of the pieces that trips up more projects than almost anything else. Call us at (424) 407-8266 - a live person answers, no voicemail queue.
Nadia Ellery founded this studio in 2015, and since then the team has designed, permitted, and built more than 900 ADUs across the San Fernando Valley. Every one of those projects carried a Title 24 compliance report sealed before permit submittal. That volume gives us a calibrated sense of what LADBS reviewers flag in this specific jurisdiction, what envelope details tend to fail on first pass, and how to write the documentation so it doesn’t come back with corrections.
When You Need Title 24 Energy Compliance
- You’re converting a garage to a living unit. Garage conversions in North Hollywood require a Title 24 report even when the square footage doesn’t change, because you’re changing the occupancy classification and adding conditioned space. The existing slab depth, wall framing, and existing roof assembly all feed into the envelope calculation.
- You’re building a new detached ADU. Any new structure permitted as a dwelling unit triggers a full Title 24 residential compliance report. This applies whether you’re framing from scratch, placing a prefab unit like an Abodu, or erecting a modular system on a new foundation.
- You’re adding a Junior ADU by converting interior square footage. JADU conversions inside the primary residence still require energy compliance documentation if you’re adding a separate kitchen or altering the HVAC configuration - a detail that surprises a lot of homeowners in the Lankershim and Noho Arts District neighborhoods.
- Your LADBS plan check came back with a Title 24 correction notice. If a previous designer submitted drawings without a compliant energy report, or submitted one that didn’t match the construction documents, you’ll receive a correction. We can take over the permit set, reconcile the report, and resubmit.
- You received a bid from a contractor who didn’t mention Title 24. This is a red flag. Any scope that delivers permitted drawings without explicitly including a Title 24 compliance report is either missing the work or planning to pass the cost to you later. Under Haven Standard Clause 1, our written price includes the report - it doesn’t appear as a line-item surprise at submittal.
- You’re financing the ADU and the lender requires a complete permit set. Several ADU lending products now require a full permit-ready set, including the energy compliance documentation, before releasing construction funds. We’ve coordinated with lenders on this requirement for projects in Toluca Lake and Valley Village.
Our Title 24 Energy Compliance Process

- Site and drawing intake. Before we run any numbers, we document what exists: wall assembly, roof slope and insulation access, window-to-floor-area ratio, and the orientation of the structure on the lot. In North Hollywood, where a significant number of lots run east-west along streets like Magnolia and Oxnard, orientation has a direct effect on the solar heat gain calculation. We record everything with photos - clients receive that photo record, not just a summary.
- Performance method compliance modeling. California’s Title 24 Part 6 allows either a prescriptive or performance compliance path. For most ADUs in the 400-1,200 sq ft range, the performance method (run through California Energy Commission-approved software) produces a better result because it lets trade-offs work in your favor - for example, higher-efficiency HVAC can offset a window area that would fail prescriptively. We use the performance path as a default and document the reasoning.
- Coordination with the architectural drawings. The Title 24 report has to match the permit drawings exactly: the window schedule, the wall assembly notes, the ceiling R-value, the duct location. Mismatches between the energy report and the drawings are the single most common cause of Title 24 correction notices at LADBS. Because our team produces both the drawings and the report under one contract, this coordination happens internally, not across a phone call between two firms.
- CF1R certificate and mandatory measures documentation. The compliance report produces a CF1R certificate - the document the field inspector stamps at framing and final. We prepare this, along with the mandatory measures checklist, as part of the permit set. You receive copies of everything before we submit.
- LADBS submittal and plan check response. We submit the permit set, including the energy compliance documentation, to LADBS and track the review. If a plan check correction comes back on the Title 24 items, we respond to it - that’s included in the scope, not billed as an extra. Haven Standard Clause 5 locks the scope at signing; there are no door-side additions when a reviewer asks a follow-up question.
- Field inspection support. When the framing inspector or final inspector asks for the CF2R or CF3R documentation (installation certificate and verification certificate), we make sure those forms are completed correctly by the installing trades and available on site. An energy compliance report that doesn’t survive field inspection is an incomplete job.
Title 24 Energy Compliance Pricing in North Hollywood
Title 24 energy compliance is included in Ellery ADU Studio’s permit set pricing - it’s not a separate line item we add after you’ve signed. The written project price you receive before work starts, per Haven Standard Clause 1, already accounts for the compliance report, the CF1R certificate, and any plan check responses related to energy items.
That said, here’s How Much Does ADU Design & Permitting Cost? (2026 Price Guide) - North Hollywood, CA when you’re comparing bids or evaluating a proposal from another firm:
- Standalone Title 24 report only (no drawings): $400-$900, depending on unit size and complexity. This is what a third-party energy consultant charges if the architect or designer hands them a completed drawing set.
- Title 24 as part of a full ADU permit set: Absorbed into the permit set fee, which at Ellery runs $8,500-$14,000 for the full design and permit package on a typical 400-800 sq ft ADU. The energy compliance report is not a separate invoice.
- Correction and resubmittal on an existing failed report: $600-$1,800, depending on how far off the original report is from the drawings and what changes are required to bring them into alignment.
- Title 24 for a JADU or garage conversion: Generally at the lower end of the range because the envelope is already defined by the existing structure. Garage conversions in North Hollywood typically need wall and ceiling insulation upgrades to meet current code, and the compliance report documents what’s required before the contractor touches anything.
Every number above comes with a caveat: the written price you receive from us is the price. If you have a written estimate from another firm and want a second opinion on whether it’s accurate and complete, we offer a Free Second Opinion at no charge. Call (424) 407-8266 to set that up.
FAQs – Title 24 Energy Compliance

What exactly is a Title 24 energy compliance report, and why does LADBS require it?
A Title 24 compliance report is a software-generated calculation that proves your ADU meets California’s energy efficiency standards for insulation, windows, HVAC, water heating, and lighting. LADBS requires it because California law (Title 24, Part 6 of the California Code of Regulations) mandates energy compliance for all new residential construction and change-of-occupancy projects - which includes both new detached ADUs and garage conversions. Without a stamped compliance report in the permit package, LADBS will not issue the building permit. Call (424) 407-8266 and we can confirm what’s required for your specific project type.
Can I use the same Title 24 report from a previous permit application on the same property?
No. Title 24 reports are project-specific: they reference the exact window schedule, wall assembly, HVAC equipment model, and orientation of the structure as shown in the submitted drawings. If the drawings change - even minor revisions to window sizes or duct routing - the report has to be updated to match. LADBS cross-references the report against the plans during plan check, and a mismatch is a common correction notice. If you have a prior report from a shelved project, we can review whether any portion of the modeling can be carried forward, but a new report tied to the current drawings is almost always required.
How much does Title 24 compliance add to my North Hollywood ADU timeline?
When the energy report is prepared in parallel with ADU Design & Blueprints - which is how Ellery structures the work - it adds zero weeks to the timeline. The report is ready when the drawings are ready, and the full package goes to LADBS in one submittal. The delay happens when the report is treated as an afterthought: a designer submits drawings, LADBS flags the missing energy documentation, and then the applicant has to locate a separate energy consultant, wait for a report, and resubmit. That sequence can add four to eight weeks to a North Hollywood permit timeline. Under our one-contract model, the two documents are produced by the same team on the same schedule.
Do prefab ADUs like Abodu or Cover need a Title 24 report if they’re manufactured off-site?
Yes, though the documentation path is slightly different. Prefab and modular ADU manufacturers typically carry a California Energy Commission module approval that covers the factory-built envelope. However, a site-specific Title 24 compliance report is still required to address the site conditions: lot orientation, climate zone (North Hollywood falls in CEC Climate Zone 9), and the connection to site utilities including HVAC and water heating. Ellery specifies and coordinates prefab systems from manufacturers including Abodu and Cover within the same single contract, so the factory documentation and the site compliance report are coordinated before submittal, not stitched together at the last minute.
Why North Hollywood’s Climate Zone Matters for Your ADU’s Energy Report
North Hollywood sits in California Energy Commission Climate Zone 9, which covers the inland San Fernando Valley. Zone 9 is characterized by hot, dry summers with afternoon temperatures regularly reaching 95-105 degrees, and mild winters that rarely drop below 40. That temperature profile has direct consequences for a Title 24 compliance model.
Cooling loads dominate. Window orientation, shading, and glazing type have outsized influence on whether an ADU passes on the performance path. A unit facing west on a Valley street in August without adequate overhang or low-SHGC glazing will fail the solar heat gain calculation. We’ve seen this pattern repeatedly on properties near Laurel Canyon Boulevard and in the Toluca Woods area, where lots tend to be narrow and ADUs end up oriented toward the street with west-facing glass.
Insulation requirements in Zone 9 also reflect the heating-cooling split: ceiling insulation is typically required at R-38 or better, and wall assemblies need to hit R-13 minimum in the cavity. For garage conversions, the existing wall framing often doesn’t have any insulation at all, so the compliance report will specify what needs to be added before the inspector signs off at framing.
Water heating is the other variable. California’s solar-ready requirements and heat pump water heater provisions apply to new ADUs in Zone 9. The compliance report documents which requirement applies based on the system configuration. If you’re adding a James Hardie-clad ADU with a new exterior wall assembly, the water heater specification is part of the compliance model - not a decision left to the contractor on the day of installation.
The One-Contract Difference on Energy Compliance

Most ADU projects in Los Angeles involve at least two firms: one that produces the drawings and another that builds. The energy compliance report usually falls in the gap between them. The designer says it’s the contractor’s responsibility to verify the installed equipment matches the report. The contractor says it’s the designer’s job to update the report if the specified equipment is out of stock. Neither is wrong, technically - but the homeowner is the one who gets the correction notice and the delay.
Ellery’s home page states this directly: one contract, one price, one point of accountability. The Title 24 report, the drawings, and the construction are all produced and executed under the same written agreement. If the installed HVAC unit changes from what was specified in the compliance report, it’s our problem to reconcile - not yours to mediate between two separate firms.
Nadia Ellery built the studio around this model specifically because the designer-versus-builder blame gap was the failure pattern she saw most often in the early years of California’s ADU expansion. The 365-Day Done Right Promise formalizes it: if the finished ADU is not built to the permitted drawings, Ellery makes it right. That includes energy compliance items that affect the final inspection.
What the Permit Set Includes
When Ellery delivers a permit set for an ADU in North Hollywood, the energy compliance documentation is not a separate attachment - it’s part of the core package. Here’s what the client receives before submittal:
- Architectural drawings, including window schedule and wall assembly notes coordinated with the Title 24 report
- CF1R compliance certificate generated by CEC-approved software, referencing the specific lot orientation and Climate Zone 9 parameters
- Mandatory measures checklist aligned with the construction scope
- Documented photo record of the existing site conditions that informed the energy model
- Written scope locked at signing, per Haven Standard Clause 5 – no additions when plan check questions arise
If the project uses a prefab system like Abodu, the factory’s CEC module documentation is assembled alongside the site compliance report as part of the same submittal package.
Key Takeaways

- Title 24 energy compliance is required for every ADU and garage conversion permit in North Hollywood – no report means no permit.
- North Hollywood’s Climate Zone 9 conditions make window orientation, glazing specs, and cooling load calculations especially consequential in the compliance model.
- Mismatches between the compliance report and the architectural drawings are the most common cause of LADBS energy-related correction notices – a one-contract model eliminates that gap.
- Standalone Title 24 reports cost $400-$900 when purchased separately; at Ellery, the report is included in the written permit set price before work starts.
- Prefab ADUs still require a site-specific Title 24 report covering orientation, climate zone, and utility connections – the factory approval doesn’t replace it.
