Title 24 Energy Compliance in Long Beach, CA

Title 24 Energy Compliance in Long Beach, CA

Title 24 energy compliance in Long Beach means your ADU or home addition meets California’s mandatory energy-efficiency standards before the city will sign off on your permit. A Title 24 report runs $250 to $900 for most ADU projects in Long Beach, and it has to be completed by a certified energy consultant using state-approved software, not by your contractor. At Benson ADU Long Beach, we handle Title 24 as part of our ADU Design & Permitting process so you’re never stuck chasing documents a week before your permit review.

Long Beach sits in California Climate Zone 8, which shapes what your Title 24 report has to account for: mild coastal temperatures mean less heating load, but west-facing windows and limited cross-ventilation in older lot layouts can push cooling requirements up. The city also enforces the 2022 Energy Code with local amendments. We manage this for you and keep the report tied directly to your project’s actual plan set. Call us at (562) 362-3885 and we’ll tell you what your project needs in plain language.

This page covers what Title 24 is, when it applies to your ADU project, what we do step by step, what it costs, and the questions we hear most from Long Beach homeowners.

Key Takeaways

• Title 24 compliance is mandatory for any new ADU, JADU, or home addition in Long Beach. No report, no building permit.
• A Title 24 report for a typical Long Beach ADU costs roughly $250 to $900, depending on project size and mechanical systems.
• The report must come from a certified energy consultant. Contractors cannot self-certify.
• Benson ADU Long Beach folds Title 24 into our design and permitting package so one team owns the whole approval path.
• Our written price covers the energy report before work starts. You’ll see it as a line item, not a surprise.

What Title 24 Actually Is

Title 24 is Part 6 of the California Code of Regulations, also called the California Energy Code. It sets minimum efficiency requirements for new construction and major alterations. For your ADU, that means your building’s envelope (walls, roof, windows, floor), lighting, water heating, and any HVAC system all have to hit specific performance targets. A certified consultant plugs your project’s plans into state-approved software and produces a report showing the math checks out.

You’ll also hear this called an energy compliance report or a performance approach calculation. Same thing. The city of Long Beach will ask for it during plan check. If it’s missing or the numbers don’t match your submittal, your permit gets held. We’ve seen projects stall for weeks over a mismatch between the architect’s window spec and the Title 24 input. That’s why we keep the energy consultant inside our permitting workflow rather than sending you off to find one on your own.

When You Need Title 24 Energy Compliance

Here are the situations where Long Beach homeowners hit a Title 24 requirement. If any of these sound like your project, we can help you get ahead of it.

• You’re building a new ADU or detached structure. Any new conditioned space triggers full Title 24 compliance, including envelope, lighting, and mechanical. There’s no exemption for small square footage.
• You’re converting a garage into an ADU or JADU. A garage conversion changes the building’s use, which means the energy report has to demonstrate the newly conditioned space meets current standards. Existing garage walls and slab often need insulation upgrades to make the numbers work.
• You’re adding square footage to an existing home. Additions over a certain size bring the altered portions of the house into Title 24 scope. The report covers the new area plus any affected systems.
• You’re replacing windows or adding a skylight as part of a larger remodel. Fenestration changes trigger Title 24 review. The report confirms your glazing choices meet the required U-factor and solar heat gain coefficient for Long Beach’s climate zone.
• Your permit was rejected or held up at plan check. If the city kicked your submittal back for missing energy documentation, we can step in, get the report done, and get your plans moving again.
• Your prefab ADU vendor says you need a site-specific energy report. Prefab itself doesn’t waive Title 24. The unit still has to be modeled against the local climate data. We do this regularly for homeowners building with Abodu and Plant Prefab models.

Not sure whether your project needs one? Call us and describe what you’re planning. We’ll tell you straight. Most ADU projects in Long Beach need a Title 24 report, but the scope and cost depend heavily on how the unit will be heated, cooled, and insulated.

Our Title 24 Energy Compliance Process

We run Title 24 as part of the overall ADU Design & Permitting in Long Beach workflow. You won’t be the one emailing a consultant back and forth. Here’s how it works with us:

1. We review your project scope. We sit down with you, look at the ADU or addition you’re planning, and identify what triggers Title 24. This includes the size, the mechanical systems, the window package, and the construction type. If you haven’t finalized plans, we guide you toward options that make compliance straightforward instead of expensive.
2. We coordinate the energy consultant. We work with a certified Title 24 consultant who runs the state-approved energy modeling software. You don’t have to vet anyone or worry about whether they’re qualified. The consultant is part of our permitting chain.
3. We get the inputs right the first time. We pull the exact wall assembly, insulation values, window specs, water heater type, and lighting details from your plan set. Garbage inputs produce a rejected report. We’ve built enough ADUs in Long Beach that we know the typical trouble spots: west-facing glazing on narrow lots, older panel upgrades affecting heat pump choices, and garage-slab insulation requirements on conversions.
4. The report is generated and reviewed. The consultant produces the Title 24 compliance documentation. We check it against your plans before it goes anywhere. Every number is traceable to a specific drawing note. If there’s a mismatch, we fix it before the city sees it.
5. We submit the full package to the city. The energy report goes in with your architectural drawings, structural calculations, and the rest of the permit submittal. One complete package, one point of contact.
6. We handle plan check corrections. If the Long Beach plan checker has questions or asks for revisions, we respond. You don’t play translator between a city reviewer and an energy consultant. We close the loop.

The whole thing typically takes one to two weeks once plans are finalized, depending on consultant availability and plan check workload. We’ll give you a written timeline before we start.

Why Title 24 Matters for Your Prefab ADU

Prefab ADUs have changed how fast a project can go from permit to move-in. But prefab doesn’t skip Title 24. The state still requires a site-specific energy report that models the unit against Long Beach’s climate data and your exact lot configuration. A unit that passes Title 24 in Fresno hasn’t passed it in Long Beach until a consultant runs the local climate file.

We’ve done Title 24 work for ADUs built with Abodu and Plant Prefab models, and the reports are straightforward when the manufacturer’s spec sheet is clean. What trips up homeowners is when the vendor says “Title 24 ready” meaning the unit meets prescriptive standards generally, but the local report still hasn’t been generated for the city. We close that gap. The same applies to more site-built setups and units using Tuff Shed shells or James Hardie cladding. The energy report cares about the whole assembly: framing, insulation, windows, and mechanicals. Cladding choice matters less for Title 24 than for wall assembly performance and durability, though the right cladding does make a real difference in Long Beach’s salt-air environment.

If you’re comparing prefab brands for your ADU, ask each vendor: “Will you produce the site-specific Title 24 report for my Long Beach address, or is that on me?” The answer tells you a lot. We’ve helped homeowners with Abodu units, Plant Prefab packages, and more traditional builds, and the ones who come to us early get through plan check faster.

Title 24 Energy Compliance Pricing in Long Beach

Here’s what you should expect to pay for Title 24 energy compliance in Long Beach. These are honest ranges based on what we see in this market, not a bait price that changes when you call.

• Small ADU or JADU (up to 500 sq ft): $250 to $450
• Standard ADU (500 to 1,000 sq ft): $400 to $700
• Large ADU or home addition (1,000+ sq ft): $550 to $900
• Garage conversion with heavy insulation upgrades: $450 to $750
• Report revisions due to plan check corrections: $100 to $250 per revision round, though we absorb most of this when it’s our error

What moves the price? The size of the project is the biggest driver. More square footage means more wall area, more glazing, more zones to model. The mechanical system matters too: a ductless mini-split is simpler to model than a central system with ducts. If you’re adding a heat pump water heater, the inputs change again. Multi-zone projects with mixed uses, like an ADU with a home office space, take longer to model.

When you work with us, the Title 24 report is a line item in your written price. Not an estimate. Not “we’ll see when we get there.” The number is on the page before you commit, and you can see exactly what it covers. If a plan check correction requires a revised report, and the error was on our side, we eat the cost. That’s the point of putting the price in writing upfront.

What Could Go Wrong Without Title 24 Compliance

We’ve seen every version of this. Here are the expensive paths homeowners accidentally walk down:

• Permit rejection at plan check. You submit drawings, the city kicks them back for missing energy documentation, and now you’re two weeks behind. Long Beach plan check turnaround is rarely fast. A missing Title 24 report makes it slower.
• Mismatched specs. Your architect specified a window, your contractor installed a different one, and the Title 24 report doesn’t match reality. The city can flag this at inspection and hold your final sign-off.
• Paying twice. You hire an energy consultant directly, the report gets rejected because the inputs don’t match your submittal, and you pay for a revision. Some consultants charge full price for re-runs.
• Installing equipment that fails compliance. You put in a water heater or HVAC unit that doesn’t meet the modeled performance. Now you’re replacing it or filing for an amendment, both of which cost money and time.

None of this is dramatic. It’s bureaucratic. But it’s exactly the kind of thing that turns a four-month project into a seven-month project. We manage Title 24 early in the design phase so it’s a checkpoint, not a crisis.

FAQs – Title 24 Energy Compliance

How much does Title 24 compliance cost in Long Beach?

Title 24 energy compliance in Long Beach typically costs $250 to $900 depending on project size and mechanical complexity. A small JADU runs on the lower end; a large ADU or addition with multiple zones runs higher. Call (562) 362-3885 for an exact quote, which we put in writing before any work begins.

Can I do Title 24 compliance myself?

No. Title 24 reports must be generated by a certified energy consultant using state-approved software, and the report must be signed by a qualified professional. Homeowners, architects, and contractors cannot self-certify. We coordinate the certified consultant for you as part of our permitting process.

Why was my permit rejected for Title 24 reasons?

A permit rejection typically means the energy report was missing, incomplete, or the inputs didn’t match your submitted plans. The fix is a corrected report that aligns with your drawings, which we handle as part of our ADU Design & Permitting in Long Beach service. In most cases, we can get a corrected report to the city within two weeks.

Does a prefab ADU still need a Title 24 report?

Yes. Prefab ADUs from manufacturers like Abodu or Plant Prefab still require a site-specific Title 24 report for your Long Beach address. The manufacturer’s national spec doesn’t satisfy the local energy modeling requirement. We produce the local report and include it in your permit submittal.

Can you come today to review my project?

In most cases, yes. Call (562) 362-3885 and tell us what you’re planning. We’ll let you know the soonest available time, and we’ll have a written estimate ready before you decide anything. Estimates are free.
