Title 24 Energy Compliance in Long Beach, CA
Title 24 Energy Compliance is California’s mandatory energy-efficiency building standard, and in Long Beach it applies to every new ADU, garage conversion, and home addition. Most Long Beach homeowners encounter Title 24 when their ADU plans are submitted for a building permit: the city won’t issue the permit until a certified Title 24 energy analysis shows the project meets current insulation, window, lighting, and HVAC requirements. We handle that analysis, the documentation, and the field verification so your ADU moves through plan check without a stall. Call us at (562) 362-4592 to find out exactly what your project needs.
Title 24 is woven into every step of our ADU Design & Permitting in Long Beach process. When we design your ADU, we size the insulation, glazing, and mechanical systems to comply from the first drawing. That matters because a retrofit fix after plan check disapproval costs time and money. Ben Ortega and the team at Seedling ADU Long Beach treat Title 24 as a design input, not an afterthought, so your permit package goes to the city clean the first time.
If you’re in Bixby Knolls, Belmont Shore, Naples, or anywhere else in Long Beach, the energy rules are the same, but the way your home meets them depends on your lot, your existing structure, and the ADU product you choose. We work with homeowners across the city, and we know which compliance paths fit which situations.
When You Need Title 24 Energy Compliance
Here are the situations where Long Beach homeowners most often need Title 24 work done, and what triggers it:
- You’re building a new detached ADU. Any new living space in Long Beach must meet current Title 24 standards for wall insulation, roof insulation, windows, water heating, and lighting. A detached ADU is treated as a new structure, so the full energy model applies from day one.
- You’re converting a garage. Garage conversions have a unique compliance path because the existing slab, walls, and roof may already have some thermal value. We document what’s already there and model only what needs to change, which often lowers your compliance cost.
- You’re adding square footage to the main house. A home addition in Long Beach triggers Title 24 review for the added space, and in some cases for the existing building systems that serve it. The energy model has to show the addition doesn’t drag the whole home below code.
- Plan check came back with a correction. If the city flagged your permit for Title 24 documentation, you need a certified energy analysis completed and submitted. We do this regularly and can turn around a correction response without redesigning your whole project.
- Your ADU changes the main home’s HVAC or water heating load. When an ADU shares systems with the primary residence, Title 24 requires the combined load to be calculated and verified. This is common in Long Beach’s older homes, where existing furnaces and water heaters were sized decades ago.
- You’re using a prefab or modular ADU product. Brands like Plant Prefab, Abodu, and Tuff Shed each have their own energy documentation, but the final submitted package still has to meet Long Beach’s local interpretation of Title 24. We handle that reconciliation so the factory documents match what the city expects.
Title 24 is not a one-size-fits-all exercise. A two-story ADU in Alamitos Heights has different glazing and shading requirements than a single-story unit in Zaferia. We run the actual energy model for your specific address and your specific plan set.
Our Title 24 Energy Compliance Process
Here’s how compliance works when you’re building with Seedling ADU Long Beach. The steps are linear, and you’ll know where things stand at every point.
- Energy modeling during design. Before your plans are finalized, we input the insulation values, window U-factors and SHGC, mechanical system efficiency, and lighting specs into certified energy modeling software. The model tells us exactly where your project stands relative to the Title 24 performance standard for Long Beach’s climate zone, which is Zone 6.
- Plan set annotation. The energy model produces a set of requirements: R-value for walls and roof, maximum window area per orientation, duct leakage targets, and fixture wattage limits. We annotate those directly onto your construction drawings so the builder and the plan checker see the same numbers.
- Certificate of Compliance preparation. We generate the CF-1R residential compliance documents required by the state. These get submitted with your permit application to the City of Long Beach’s Development Services Department. Without them, your permit package is incomplete.
- Field verification during construction. After the building is framed, insulated, and mechanically roughed in, a certified Title 24 HERS rater performs the field verification. They check insulation installation, duct sealing, window installation, and lighting. Our process includes coordinating that inspection so there’s no scheduling gap.
- Certificate of Occupancy documentation. The final step is the CF-2R and CF-3R forms, which document the field verification and the final compliance status. The City of Long Beach requires these before the final inspection sign-off on your ADU.
Throughout this process, the same Cedarwell Care Promise applies to your existing home. When our team or the HERS rater walks through your house to access the attic, the crawlspace, or the electrical panel, shoe covers go on. Drop cloths go down. If we’re working near kids’ bedrooms during naptime, we move the schedule. And before anyone leaves, you get a photo of the clean-up.
Title 24 Energy Compliance Pricing in Long Beach
Title 24 compliance cost in Long Beach typically runs between $850 and $2,400 for the energy modeling, documentation, and coordination on a standard ADU project. Field verification by a HERS rater is usually a separate line item, ranging from $300 to $700 depending on the size of the ADU and the number of visits required. Here’s how that breaks down:
| Service | Typical Range in Long Beach | What It Covers |
|---|---|---|
| Energy modeling (CF-1R) | $350 – $800 | Running the compliance model for your specific plan set and climate zone |
| Documentation package | $250 – $600 | Certificate of Compliance, plan annotations, and permit submittal support |
| HERS field verification | $300 – $700 | Site visit to verify insulation, ducts, windows, and lighting |
| Correction response (if needed) | $100 – $300 | Re-running the model or revising documents after plan check comments |
| Full compliance coordination | $850 – $2,400 | Combined modeling, documentation, verification scheduling, and final close-out |
What actually moves your price within these ranges depends on a few things. A garage conversion often costs less because part of the existing building is already modeled as existing envelope, so we’re not starting from zero. A two-story ADU with a lot of west-facing glass in coastal Long Beach will cost more because the energy model has to work harder to meet cooling requirements. The complexity of your mechanical system matters too: a ductless mini-split is straightforward to document, while a shared HVAC system with existing ductwork to the main house takes more modeling time.
Every Title 24 compliance engagement with Seedling ADU Long Beach gets a written price before any work begins. That’s not a courtesy, it’s how we operate. If we see something during the process that would add cost, we tell you before we do it. No surprise line items after the fact.

Title 24 and Prefab ADUs in Long Beach
If you’re considering a prefab or modular ADU from a brand like Plant Prefab, Abodu, or Tuff Shed, the Title 24 picture looks a little different. These manufacturers provide their own energy documentation, usually based on a standard California climate zone. But Long Beach’s specific requirements, including the marine influence and the city’s local amendments, sometimes mean the factory documents need adjustment before the city accepts them.
We’ve worked with all three of these manufacturers’ documentation packages, plus James Hardie siding integrations on site-built ADUs. What we do for prefab projects is review the manufacturer’s Title 24 paperwork, run the address-specific model for your Long Beach lot, and prepare the final compliance package the city actually demands. That closes the gap between what the factory produced and what the plan checker wants to see.
What Title 24 Grade Compliance Means for Your Long Beach Home
Title 24 compliance isn’t just a paperwork hurdle. The energy model requires real construction features that change how your ADU performs. Here’s what you can expect to find in the finished building:
- Insulation with specified R-values. Long Beach’s climate zone typically requires R-13 to R-21 in walls and R-30 to R-38 in ceilings, depending on the construction type. The model dials in the exact number for your situation.
- Low-E windows with climate-appropriate glass. Coastal Long Beach buildings prioritize solar heat gain management over extreme cold protection. The compliance model picks the window specs that balance light, heat, and energy use.
- High-efficiency water heating. Most Title 24-compliant ADUs in Long Beach use tankless gas or heat pump water heaters, which reduces the static energy load of the building.
- LED lighting with occupancy sensors where required. Title 24 has specific requirements for high-efficacy lighting in kitchens, bathrooms, and outdoor fixtures, with vacancy sensors in certain rooms.
- Sealed and tested ducts. If your ADU has ducted heating or cooling, the HERS rater tests the duct leakage. Title 24 allows only a small percentage of leakage, and the verification catches it before drywall goes up.
These are the things that show up in your home and in your utility bills. The compliance model isn’t theoretical; it’s a set of build instructions that produce a measurable result.
FAQs – Title 24 Energy Compliance
What is Title 24 and why does my Long Beach ADU need it?
Title 24 is the California Energy Code, and it sets minimum requirements for insulation, windows, lighting, HVAC, and water heating in new construction and major renovations. The City of Long Beach requires a Title 24 compliance certificate before a building permit is issued for any new ADU, garage conversion, or home addition. Without the certificate, your permit application stops at plan check. Call (562) 362-4592 and we can tell you exactly what documentation your project needs.
How much does Title 24 compliance cost for an ADU in Long Beach?
Title 24 compliance for a standard ADU in Long Beach typically costs between $850 and $2,400 for modeling and documentation, plus $300 to $700 for the required field verification. Your actual cost depends on the size of the ADU, whether it’s a detached unit or a garage conversion, and the mechanical systems involved. We provide a written price before any work starts, so you’ll know your number before you commit.
Can Title 24 compliance be done the same week?
In most cases, yes. Energy modeling and documentation for a straightforward ADU can be completed within a week of receiving your plan set. Field verification gets scheduled after the building reaches the appropriate construction stage, which usually lands a few weeks into the build. If you’re on a tight timeline, call (562) 362-4592 and we’ll give you a realistic schedule for your specific project.
What happens if my ADU fails the Title 24 field verification?
If the field verification finds an issue, such as insulation gaps, duct leakage above the tested limit, or incorrect fixture installation, the deficiency gets documented and we correct it before drywall or finishes cover the area. The HERS rater then returns for a re-check. This is one of the reasons we run the energy model early and annotate the plans carefully: it reduces the chance of a failed verification in the first place.
Is Title 24 compliance included in Seedling’s ADU design and permitting service?
Yes. Our ADU Design & Permitting in Long Beach service includes Title 24 energy modeling, documentation, and verification coordination as part of the complete permit package we prepare for the City of Long Beach. You won’t be handed off to a separate compliance company or asked to source your own energy consultant.
Are there Long Beach-specific Title 24 requirements I should know about?
Long Beach is in Climate Zone 6, which shapes the baseline energy budget for your project. The city also applies local amendments to the California Green Building Standards, which can affect water heating and landscape requirements alongside Title 24. We build these local nuances into your compliance model so there are no surprises at plan check.
