Title 24 Energy Compliance in Van Nuys, CA

Title 24 Energy Compliance in Van Nuys, CA

Every ADU permitted in Van Nuys must pass California’s Title 24 Energy Code review before the building department will issue a permit. That means your drawings need a completed CF1R compliance form, a HERS verification plan, and envelope, mechanical, and lighting calculations that satisfy the California Energy Commission’s 2022 standards – which are currently the strictest residential energy standards in the country. At Ellery ADU Studio, our ADU Design & Permitting services build the Title 24 package directly into the permit set we produce for you, so there is no hand-off to a third-party energy consultant and no gap between the drawings and the compliance documentation. Call us at (424) 523-8492 if you have a set of drawings already in hand and want a second opinion on whether the energy package holds up.

We handle ADU Design & Permitting in Van Nuys as a single contract – design, Title 24, and construction together – so the energy compliance work is never an afterthought produced by someone who has never seen your site. Nadia Ellery and the studio team have worked through the Los Angeles Department of Building and Safety’s electronic plan check process hundreds of times, and we know exactly where Title 24 packages get flagged at the Van Nuys district office specifically.

When You Need Title 24 Energy Compliance

Title 24 applies to virtually every ADU project in Van Nuys, but the specific deliverables vary by project type. Here are the situations we see most often:

• New detached ADU on a Van Nuys lot. A new structure requires a full CF1R energy compliance report, an orientation-aware solar access calculation, and confirmed insulation R-values for the roof, walls, and slab or raised floor. Van Nuys lots tend to be oriented east-west on the grid, which affects fenestration trade-offs in the south-facing compliance model.
• Garage conversion to living space. Converting a garage triggers Title 24 because you are changing the occupancy class. The existing slab and wall framing almost never meet current energy standards on their own, so the compliance package must account for continuous insulation added to the interior or exterior of the framing – a detail that directly affects your finished square footage and your framing budget.
• Junior ADU carved from interior square footage. Even a JADU created inside the primary residence needs its own envelope calculation if it has a separate entrance and mechanical system. LADBS has flagged JADU packages in Van Nuys for missing this step, which adds weeks to plan check turnaround.
• Permit already rejected for energy non-compliance. If your current drawings came back from plan check with a correction letter citing CEC Title 24 Part 6, you need a corrected CF1R and potentially a revised HERS rating plan before resubmission. We review correction letters and correct the energy package – see the Free Second Opinion offer below.
• Prefab or modular ADU installation. Units from brands like Abodu or Cover arrive with their own factory energy documentation, but LADBS still requires a site-specific CF1R that ties the unit’s envelope data to your specific lot orientation, local climate zone (Van Nuys sits in CEC Climate Zone 9), and the mechanical system you are connecting on-site. The factory package alone is not sufficient.
• Solar-ready or all-electric ADU requirement. California’s 2022 Title 24 standards require new ADUs to be solar-ready and, in many configurations, to meet all-electric readiness requirements. If your drawings were produced before 2023 and have not been updated, they likely do not reflect these requirements.

Our Title 24 Energy Compliance Process

We do not outsource the energy compliance work. Nadia Ellery’s team runs the calculations, produces the CF1R, and coordinates the HERS verification plan in-house, so the compliance package and the architectural drawings are consistent from the first submittal. Here is how it works:

1. Site assessment and climate zone confirmation. Van Nuys is CEC Climate Zone 9 – a mixed climate with hot, dry summers and mild winters. That zone assignment drives the baseline U-factor and SHGC requirements for your windows, the duct-leakage thresholds, and the minimum EER ratings for any HVAC equipment specified. We confirm the zone assignment and the lot orientation before we touch the energy model.
2. Envelope design and trade-off analysis. Title 24 allows a performance path trade-off: if you exceed the code minimum in one area (say, a higher-R roof assembly using James Hardie fiber-cement cladding over a continuous foam layer), you can take credit against a slightly lower-performing area. We run the trade-off model to find the configuration that meets code at the lowest construction cost, and we document every assumption so there are no surprises when the contractor orders materials.
3. CF1R report production. We produce the Certificate of Compliance (CF1R) using CEC-approved energy calculation software. The form lists every envelope component, every mechanical system specification, and the compliance margin – positive or negative – for each measure. This is the document LADBS requires to issue the permit.
4. HERS verification plan coordination. Certain measures on the CF1R – duct sealing, refrigerant charge, window U-factor, and others – require field verification by a certified HERS rater after installation. We identify which measures apply to your project, note them in the permit set, and coordinate the HERS rater schedule so field verification does not sit on the critical path and delay your Certificate of Occupancy.
5. Plan check response and correction support. If LADBS’s plan checker raises a Title 24 correction, we respond to it as part of the same contract. You do not pay extra for a correction round that results from our package – that is documented in the written project scope you receive before work starts, per Haven Standard Clause 1.
6. Final CF6R documentation at project close. At construction completion, we compile the Certificate of Installation (CF6R) records from the HERS rater and the installing contractors, and we deliver a full documentation package to you – not a summary email, but the actual signed compliance certificates you will need if you ever refinance, sell, or pull a future permit on the property.

Title 24 Energy Compliance Pricing in Van Nuys

Title 24 compliance is included in Ellery ADU Studio’s ADU Design & Blueprints package within our full design-build contract, not billed as a separate line item add-on. That said, here is how the energy compliance component breaks out when we scope a project, so you know what is in the number you receive in writing:

Every number above is paired with a written price before any work starts – that is Haven Standard Clause 1, and it applies to every project we take on in Van Nuys without exception. The written scope locks in what the energy compliance work includes, so there is no door-side upsell when the HERS rater shows up or when a plan check correction comes back.

What moves the number inside those ranges - and what shapes How Much Does ADU Design & Permitting Cost? (2026 Price Guide) - Van Nuys, CA - is lot orientation and window-to-wall ratio (more east-west glass means more trade-off modeling time), the mechanical system specified (all-electric heat pump systems require additional documentation under the 2022 standards), and whether the existing structure has any documentation on its current insulation assemblies. Garage conversions in Van Nuys neighborhoods like Sylvan Park and the blocks north of Sherman Way often have 1960s-era framing with no wall insulation at all, which requires a more detailed envelope upgrade analysis than a garage built after 1980.

Why Title 24 Gets Projects Stuck in Van Nuys

The Van Nuys district office processes a high volume of ADU plan check submittals, and energy compliance is one of the most common reasons for a correction letter. A few patterns we see repeatedly:

First, CF1R packages produced by generalist drafters or online permit-service platforms often use default compliance assumptions rather than site-specific calculations. The default values pass the software check but sometimes fail the plan checker’s review when the project conditions do not match the defaults – for example, when a flat roof is specified but the software was run with a standard sloped-roof assembly.

Second, the 2022 Title 24 all-electric readiness requirements catch projects that were scoped in 2022 or early 2023 using the prior standards. If your drawings reference a gas water heater or a gas furnace as the primary heating source, a plan checker applying the current standards will issue a correction. The fix is not complicated, but it requires a revised mechanical specification and a re-run of the CF1R.

Third, HERS verification coordination is often missing from permit sets produced by designers who do not build the project themselves. When the designer and contractor are separate parties, neither one owns the HERS scheduling problem, and the project stalls before the Certificate of Occupancy can be issued. In Ellery’s one-contract model, the HERS coordination is part of the construction phase scope – it cannot fall through a gap between parties because there is only one party.

FAQs – Title 24 Energy Compliance in Van Nuys

What is Title 24 energy compliance, and does it apply to my Van Nuys ADU?

Title 24 Part 6 is California’s Building Energy Efficiency Standards, and it applies to every new ADU and every garage conversion or interior conversion that changes occupancy in Van Nuys. The code sets minimum performance requirements for insulation, windows, lighting, and HVAC systems, and requires a certified CF1R compliance report as part of the permit application. There are no exemptions based on ADU size – even a 250-square-foot JADU in Van Nuys requires a CF1R. Call (424) 523-8492 if you are not sure whether your specific project triggers the full compliance package or a simplified path.

How long does Title 24 compliance add to the Van Nuys permit process?

When the energy package is prepared correctly the first time, it adds zero time to the permit timeline – it is reviewed concurrently with the structural and architectural drawings during LADBS plan check, not sequentially. When the package has errors or missing documentation, a single correction round at the Van Nuys district office typically adds four to eight weeks to the process, because you go to the back of the plan check queue on resubmittal. That is the core reason we produce the CF1R in-house rather than using a third-party service that produces a generic package.

Can I use the Title 24 documentation from a prefab brand like Abodu or Cover for my LADBS permit?

Factory energy documentation from a prefab manufacturer covers the unit’s envelope and systems as built in the factory. It does not cover your specific lot orientation in Van Nuys, the mechanical connection details on your site, or the solar-ready documentation LADBS requires for the site permit. You still need a site-specific CF1R that references the factory data but ties it to your project’s actual conditions. We produce that document as part of the site-prep and permitting scope for prefab installations – the factory package and the site CF1R are two separate deliverables, and both are required.

What happens if my ADU fails the HERS field verification after construction?

A failed HERS field verification – typically for duct leakage, refrigerant charge, or window installation – means the HERS rater cannot sign off on the CF6R, which means LADBS will not issue a Certificate of Occupancy. The fix depends on what failed: duct leakage failures usually require resealing and a retest, while window failures sometimes require reinstallation. Under the Ellery 365-Day Done Right Promise, if a field verification failure results from installation work that did not match the permitted drawings, we make it right at no additional cost to you – that commitment is in writing before the project starts.
