Title 24 Energy Compliance in Austin, TX

Title 24 Energy Compliance in Austin, TX

Title 24 energy compliance in Austin means your ADU, garage conversion, or home addition meets California’s building energy efficiency standards before a permit gets issued. Most Austin homeowners encounter this requirement when their designer submits plans and the permitting office asks for a Title 24 report: a document that models lighting, insulation, windows, HVAC, and water heating to prove the structure won’t waste energy. At Seedling ADU Austin, we handle Title 24 compliance as part of our ADU Design & Permitting in Austin process, so families never have to chase down a third-party consultant or stall their project waiting on paperwork. Call us at (254) 615-3842 if you’ve been told you need a Title 24 report and want to know exactly what it will take.

What surprises most homeowners is that Title 24 isn’t a form you fill out once and forget. It’s a performance standard that runs through the whole project: the window glass you choose, the insulation value in the walls, the efficiency rating of the mini-split system, even the type of thermostat. If any of those change mid-build, the compliance model has to be updated and resubmitted. Our job is to keep that process invisible. We review the energy details during design, run the compliance documents, and stay in front of the permitting office so your project doesn’t sit in review limbo.

Ben Ortega, our owner, reviews every Title 24 submittal personally before it goes to the city. That’s the kind of attention this paperwork demands. One missed line item can send plans back for corrections, and corrections cost time. We’d rather catch the issue at our desk than hear about it from a plan reviewer.

When You Need Title 24 Energy Compliance

Here are the situations we see most often in Austin. If any of these sound familiar, you’ll need Title 24 documentation before your permit will clear.

• You’re building an ADU from scratch. Any new detached or attached accessory dwelling unit in Austin requires a Title 24 energy report as part of the permit package. The model covers the entire structure, from slab insulation to roof assembly.
• You’re converting a garage into living space. A garage conversion changes an unconditioned space into a conditioned one, which triggers Title 24 review. This is where we often see compliance gaps: old garage slabs without insulation, uninsulated walls, and windows that were never meant to keep heat out of a bedroom.
• You’re adding square footage to your home. Any addition that creates new conditioned space falls under Title 24. The report has to show the addition complies on its own, and in some cases it triggers a review of the existing home’s systems too.
• You’re replacing windows or HVAC as part of a larger remodel. If your ADU project touches the main house at all, say you’re upgrading the electrical panel or tying into the existing HVAC, the new equipment has to meet Title 24 minimums. We document that during design.
• Your designer or architect doesn’t handle energy compliance in-house. Many Austin designers focus on floor plans and elevations, then hand off the energy work to someone else. We manage that handoff so nothing falls through the cracks.
• Your permit got flagged for a missing Title 24 report. This happens more than you’d think. A homeowner pulls a permit, the city reviews the plans, and the whole thing stalls because there’s no energy documentation. We step in, run the report, and get the project moving again.

Our Title 24 Energy Compliance Process

Here’s how we handle Title 24 from start to finish when you work with Seedling ADU Austin.

1. Drawing review. We start with your architectural drawings and a walkthrough of the proposed space. We’re looking at insulation values, window specifications, lighting counts, HVAC sizing, and water heating. If you’re working with a prefab brand like Abodu or Cover, we already know their typical assemblies and how they perform in Austin’s climate, which speeds up the modeling.
2. Compliance modeling. We run the energy model using the current Title 24 software and standards. This gives us a pass/fail picture and shows exactly which components need adjusting. Sometimes it’s as simple as selecting a different window package. Other times it means upgrading the wall insulation or choosing a higher-efficiency heat pump.
3. Recommendations in plain language. We don’t hand you a stack of energy jargon. We tell you what passed, what didn’t, and what your options are. If a more efficient window means the difference between compliance and a redesign, we’ll price that tradeoff honestly before you spend a dollar on changes.
4. Documentation and submittal. Once the model passes, we prepare the Title 24 report in the format the Austin permitting office expects. We submit it with your permit package or provide it to your designer if they’re handling the submittal.
5. Corrections and revisions. If the plan reviewer flags something, we respond directly. We don’t make you play messenger between the city and an energy consultant. Most corrections are minor, but they still get handled within a day or two.
6. Field verification. When construction is done, the city may ask for a final verification that the building matches what was modeled. We work with your contractor or our own crew to confirm the installed insulation, windows, and HVAC match the approved report. If we built the project, our 365-Day Done Right Promise already covers any discrepancy.

Title 24 Energy Compliance Pricing in Austin

Title 24 compliance work in Austin typically runs between $450 and $1,800 depending on the size and complexity of your project. A simple garage conversion with one bedroom and standard finishes sits at the lower end. A two-story ADU with multiple HVAC zones, custom glazing, and a solar component lands at the higher end. Here’s a breakdown of what drives the cost.

If you’re working with a prefab manufacturer like Tuff Shed for a base structure or James Hardie for siding and exterior finishes, the Title 24 model still has to include the full assembly. Prefab doesn’t skip the energy code; it just means the manufacturer’s specs get plugged into the model, which sometimes saves a round of back-and-forth.

Every Title 24 compliance package from Seedling ADU Austin comes with a written price before we start the work. You’ll know the cost of the report, any design changes that affect it, and what to expect from the permitting office. No surprise line items after crews arrive.

FAQs – Title 24 Energy Compliance

Is Title 24 the same as a HERS rating?

No. Title 24 is the California energy code, and the report shows your project complies with it. A HERS rating is a separate score that measures a home’s actual energy performance after construction. Austin projects may need both, but the Title 24 report comes first during permitting. Call (254) 615-3842 if you’re not sure which documents your project needs.

Can I skip Title 24 compliance on a small garage conversion?

You cannot skip Title 24 compliance if the space is becoming conditioned living area, even if it’s small. Any new conditioned square footage triggers the requirement. A one-room garage conversion in Austin still needs a compliant energy report before the permit will clear. We handle these small projects the same way we handle full ADUs: written pricing, straightforward modeling, and no surprise charges.

How long does a Title 24 report take?

A straightforward Title 24 report for a standard ADU typically takes three to five business days once we have the drawings and specifications. If the model reveals non-compliance and we need to adjust window packages or insulation values, that adds a few more days. If the permitting office sends comments back, we turn around corrections within a day or two. Call us at (254) 615-3842 and we’ll give you a more specific timeline for your project.

What happens if my project fails the Title 24 model?

If your project fails the Title 24 model, we identify exactly which components are dragging the score down and present your options. Common fixes include upgrading from a basic window package to a low-E double-pane option, increasing wall or roof insulation, or selecting a higher-efficiency heat pump. We price each option before you commit, and we’ll tell you which changes give you the most compliance value for the least money. The goal is to get your project permitted without paying for upgrades you don’t need.

Does Seedling handle the permit submittal too?

Yes. Title 24 compliance is part of our broader ADU Design & Permitting service, so we can prepare the energy report and submit the full permit package. If you already have a designer or permit expediter, we can work alongside them and just handle the Title 24 documentation. Either way, you get one clear point of contact.
