Title 24 Energy Compliance in Pasadena, CA
Title 24 Energy Compliance is the California energy code every new ADU, garage conversion, and room addition in Pasadena must pass before the city issues a final permit sign-off. A Title 24 report runs your project’s plans through state-mandated software, verifies the insulation values, window ratings, HVAC sizing, and lighting efficiency against current California Building Standards, and produces the documentation Pasadena’s Building & Safety division requires. Most homeowners hit Title 24 as a surprise requirement at plan check, right when the permit review stalls. We prepare the compliance report as part of ADU Design & Permitting in Pasadena, so it gets filed correctly the first time and your project doesn’t sit on hold.
Fielding ADU Pasadena handles Title 24 compliance on every project we build. Reed Calloway, our owner, has run Pasadena ADU and addition projects through the full permit pipeline enough times to know exactly what the plan checker at 175 N. Garfield Ave. will flag on a Title 24 report. That matters because a rejected energy report sends your drawings back to the preparer, burns two to four weeks, and pushes your start date out. We’d rather hand you a written price, file clean paperwork, and pull your permit on schedule. Call (626) 657-5541 and we’ll tell you whether Title 24 is required for your specific project, and what it will cost. No charge for the conversation.
When You Need Title 24 Energy Compliance
If you are building, converting, or adding square footage in Pasadena, you almost certainly need a Title 24 energy report at plan check. Here are the specific situations where it applies:
- You are building a detached ADU in the backyard. Every new dwelling unit, including a 400-square-foot studio above a garage, needs a full Title 24 compliance package. No exceptions.
- You are converting a garage into living space. The energy report covers the new insulation you add to the slab and walls, the windows you cut into the existing framing, and the mini-split or HVAC system you install.
- You are adding a room or bumping out a wall. Even an 80-square-foot laundry room addition triggers Title 24 if you are touching the building envelope or adding conditioned space.
- Pasadena’s plan check flagged your current submittal. This is the most common call we get: a homeowner filed for permit with a builder or draftsman, and the reviewer returned the plans with “Title 24 documentation required” stamped on the cover sheet.
- You bought a prefab or modular ADU and need the site-specific energy report. Units from Abodu, Cover, and Dvele arrive with their own modeling, but the city still wants a Title 24 report that ties the factory data to your Pasadena lot conditions.
Our Title 24 Energy Compliance Process
The Title 24 work is a defined, repeatable sequence. We’ve stripped it down to the steps that actually matter, and we put your price in writing before any of them begin.
- Plans in hand, scope defined. We need a preliminary floor plan and elevations. If you don’t have them yet, our ADU Design & Permitting team draws them as part of the same contract.
- Energy model run. We input your project into the current California Energy Commission-approved software. The model accounts for your wall insulation, attic or roof insulation, window U-factor and SHGC, door tightness, HVAC type, duct location, and lighting wattage.
- Compliance documents generated. The software produces the forms Pasadena wants to see: the CF-1R (compliance registration), the envelope measures, the mechanical system summary, and the solar-ready or photovoltaic requirement if your project triggers it.
- Plan check submittal. We file the Title 24 report with your permit drawings so the plan reviewer sees everything in one package. When the report matches the plans, review moves faster.
- Verification paperwork at final inspection. When the build is done, the city wants the CF-2R forms signed by the HERS rater (if required) and the installer’s compliance statement. We coordinate that sign-off with Pasadena Building & Safety so your final inspection clears.
Title 24 Energy Compliance Pricing in Pasadena
Title 24 pricing is not a mystery, and you should not pay a premium to find out what it costs. The report itself is one component of a broader permit package, but if you’re hiring us to run compliance on a project someone else is building, here are the numbers we quote in Pasadena.
A standalone Title 24 energy report for a simple ADU or garage conversion in Pasadena typically runs $450 to $950. That covers the modeling, the compliance documents, and the final CF-2R verification paperwork. If your project includes photovoltaic panels, complex wall assemblies, non-standard HVAC, or a multi-unit structure, the report can reach $1,400 to $2,200 because the modeler has more inputs to handle. If HERS field verification is required – the independent inspector who confirms insulation and duct sealing on site – that typically adds $300 to $600 in Pasadena, and it is a separate charge from the report itself.
Three things push the price of Title 24 compliance up or down:
- Who draws the plans. When our design team and our energy team work from the same set of drawings, there is no back-and-forth correction loop. When we’re modeling someone else’s plans, we often have to request missing details, and that adds time and cost.
- What kind of build method you chose. Conventional stick framing with 2×6 walls and batt insulation models differently than a prefab unit from Abodu or Cover. The prefab platforms ship with factory energy data; the work is translating that into the California forms, which is often faster.
- Whether changes are required to pass. If your windows are single-pane or your HVAC is undersized for the new square footage, the report shows a failing score. Fixing the design and re-running the model costs more than a plan that passes the first time.
You will get a written price before we start any Title 24 work. The number on that page is the number on the final invoice, same as every Fielding ADU Pasadena job. And the report carries the Garrison Standard behind it: if a compliance document we filed has an error we should have caught, we correct it at our cost, not yours.

FAQs – Title 24 Energy Compliance
What does Title 24 actually require for an ADU in Pasadena?
Title 24 requires your ADU’s envelope (walls, roof, floor, windows), mechanical system, water heating, and lighting to meet the current California energy efficiency standards as modeled by approved software. For a typical Pasadena ADU, that means R-13 or better wall insulation, a high-efficiency mini-split or HVAC system, LED lighting throughout, and sealed ducts or a ductless configuration. Solar is generally not required for most detached ADUs under California’s current code, but a photovoltaic-ready zone or actual panels may be triggered depending on the size and orientation of the structure. We run the model first, show you the score, and then we talk about what – if anything – needs upgrading. If your ADU fails the model, the fix is often a window spec change or a bump in insulation, not a redesign. Call (626) 657-5541 and we’ll tell you what your specific project will require.
How long does Title 24 compliance take in Pasadena?
A straightforward ADU or garage conversion Title 24 report takes three to five business days once we have the plans in hand. If the project is complex – multi-story, attached to an existing dwelling, or includes photovoltaics – the modeling window stretches to two weeks. The time risk is not the report itself; it is plan check resubmittal. When Title 24 documents are filed incomplete, the Pasadena building department sets the permit aside and the clock keeps running. We file complete the first time. If you are under a schedule pressure – a tenant moving in, a refi deadline – tell us, and we will tell you honestly whether the timeline works.
Is Title 24 the same thing as the HERS test?
No. Title 24 is the code itself and the documentation that proves compliance. HERS (Home Energy Rating System) is the field verification process that confirms the building was actually constructed as the Title 24 paperwork says it was. Not every project needs a HERS rater. When one is required for duct sealing or insulation verification, a state-certified HERS rater comes to the Pasadena site during construction, runs the diagnostic test, and signs the CF-2R form. We coordinate that step so the inspector’s visit lands at the right phase of the build, not after the drywall goes up. The HERS test in Pasadena typically runs a few hundred dollars, paid directly to the rater.
Can I skip Title 24 and just build it without the report?
No, not in Pasadena, and not anywhere in California. The city will not issue a final permit sign-off without a passing Title 24 compliance package on file, and an unpermitted addition creates problems when you sell, refinance, insure the property, or get cited by code enforcement. Some contractors tell homeowners they’ll “handle it later” or skip the paperwork to save money. That is the kind of shortcut that leaves a homeowner holding a structure the city will not recognize. We do the paperwork by the book, every time. If you already started a project without Title 24, call us. We can often bring an existing unpermitted build into compliance without tearing it down, depending on what is behind the walls.
Does Fielding ADU Pasadena handle Title 24 for projects another contractor is building?
Yes. We run Title 24 compliance reports as a standalone service for Pasadena homeowners, draftsmen, and other builders. We model the plans, produce the documentation, file it with the city, and handle the HERS coordination if needed. You do not have to use us for the construction work to use us for the energy compliance. The same written-price rule applies: you approve the number before we start, and the number does not move. If you need a full ADU built, we can also carry the whole project from ADU Design & Permitting through final inspection under one contract.
What will Title 24 stop me from doing in my Pasadena project?
The most common Title 24 pitfalls in Pasadena are undersized windows, single-pane glass in a garage conversion, and an old furnace trying to heat new square footage it cannot handle. The code does not stop you from building; it forces certain minimums. Sometimes a homeowner wants a wall of floor-to-ceiling glass on a west-facing ADU wall, and the model says the solar heat gain fails the threshold. The fix is usually triple-glazed or low-SHGC glazing, not a smaller window. We tell you what the model says, what the code requires, and what the cheapest compliant fix is. That is the value of running the report before framing starts: you make the changes on paper, not with a reciprocating saw.
Title 24 and Prefab ADUs: What Pasadena Homeowners Should Know
If you’ve been researching an Abodu or Cover prefab ADU for your Pasadena lot, you’ve probably read that the factory handles “compliance.” The factory units are designed and assembled to Title 24 standards, which is accurate. But the city still requires a site-specific energy report that marries the factory data to your property: the specific orientation, the shade from your neighbor’s oak tree, the exact glazing package on your unit, and the foundation type you chose. That report is produced by a Pasadena energy modeler who inputs the factory specs into California’s compliance software. The same applies to Dvele units, which ship with high-performance envelopes but still need the site report filed for the permit record.
We work with all three platforms regularly. We know their standard wall assemblies, their window packages, and their typical HVAC configurations, which means the modeling work is faster and the submittal is cleaner. If you’re still choosing between a prefab unit and a conventional build, we’ll walk you through the real difference in Title 24 cost and complexity. Conventional framing with R-13 walls, a ductless mini-split, and standard window packages passes easily if the design is kept simple. A prefab unit with aggressive glazing packages may need a more careful model and more expensive windows to clear the bar. Either path works; the pricing depends on the specific details.
Why Title 24 Work in Pasadena Is Different
Climate zone matters in Title 24 modeling, and Pasadena sits in California climate zone 9, which carries specific requirements for cooling, glass, and roof insulation. What passes in Pasadena is not automatically what passes in nearby La Cañada Flintridge, which sits in a different zone with different heating and glazing thresholds. Our models are built for the Pasadena-specific requirements, including the city’s adoption of the 2022 Energy Code, which upped the requirements for heat pump readiness and battery storage capacity on some project types.
Pasadena also handles plan review through its own Community Development Department rather than a county office, which means the review staff have their own checklists and their own interpretation patterns. We know what they flag and what they ignore. That knowledge is not something a generic online energy-report service has. It comes from sitting through permit reviews in this specific building department and figuring out what passes the first time and what gets a correction notice.
