Title 24 Energy Compliance in Riverside, CA
Title 24 Energy Compliance in Riverside means your ADU, garage conversion, or home addition meets California’s mandatory energy efficiency and building envelope standards before the city will sign off on your permit. If your project falls short on insulation, windows, lighting, or HVAC efficiency, the Riverside building department will not issue a final certificate of occupancy. Lodgewick ADU Riverside handles Title 24 documentation and compliance as part of our ADU Design & Permitting in Riverside service, so your energy calculations, compliance forms, and field verification are handled by one team instead of bounced between a designer, an energy consultant, and a confused homeowner. Call (831) 292-4191 and we will tell you exactly what your project needs to pass.
We are the ADU specialists of the Kingswell family. The name Lodgewick comes from an old idea: a lodge is a small house on a larger property, which is exactly what an ADU is. Since 2010, we have helped Riverside homeowners get their projects through Title 24 compliance without surprises, and every job runs under The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee delivered before we start.

When You Need Title 24 Energy Compliance
Title 24 applies to almost every residential construction project in California, but homeowners often do not realize they need it until the city asks for documentation. Here are the situations where Riverside homeowners hit a Title 24 wall:
- You are building an ADU or JADU. Any new accessory dwelling unit, whether attached, detached, or a garage conversion, must meet current Title 24 energy standards. The compliance forms are part of your permit submittal, not an add-on you can skip.
- Your garage conversion is moving from “storage” to “living space.” The moment a garage becomes a habitable room, it needs insulation, a proper envelope, and energy compliance documentation. Riverside inspectors check this carefully because garage conversions are common in neighborhoods like Canyon Crest, Wood Streets, and La Sierra.
- Your addition is over 1,000 square feet. Larger additions trigger more detailed Title 24 calculations, including HVAC sizing and whole-house energy modeling. Smaller bump-outs still need compliance forms, just less extensive ones.
- You are replacing windows or adding a mini-split system. Even smaller retrofit projects can require Title 24 documentation when you change the building envelope or mechanical systems. Window replacements in older Riverside homes, especially pre-1980 builds, often need compliance forms.
- The city issued a correction notice. If the Riverside building department flagged your permit for missing Title 24 documents, you need a fast fix. We regularly step in for homeowners who got stuck after a designer or draftsperson filed incomplete energy forms.
- Your energy consultant disappeared. This happens more often than it should. A homeowner pays someone for Title 24 calcs, the person files something incomplete, and then stops answering calls. We fix the paperwork and get the project moving again.
If any of these sound like your situation, call us. We will look at your project, tell you exactly what documents you need, and give you a written price before anything starts.
Our Title 24 Energy Compliance Process
We do not hand you a form and wish you luck. Here is how we handle Title 24 for Riverside ADU and addition projects, step by step.
- We review your plans and project scope. We look at your drawings, your site, and what the city already has on file. We identify exactly which Title 24 forms apply: CF1R for the design phase, CF2R for field verification, and CF3R for the final certificate. We also check whether your project falls under the prescriptive approach or needs performance modeling.
- We run the energy calculations. Using approved compliance software, we model your building envelope, window performance, insulation levels, lighting, and mechanical systems. Riverside’s climate zone (Zone 10) has specific cooling-dominant requirements, and we size everything to those numbers, not a generic California average.
- We give you a written compliance report and a written price for any corrective work. If your plans already pass, great. If they do not, we tell you exactly what needs to change, what is costs, and what the cheapest compliant path looks like. No verbal ballparks. No price changes at the door. Written, every time.
- We file the Title 24 documents with the Riverside building department. We submit the CF1R forms as part of your permit package and coordinate with the city so the review does not stall. We track the submittal and handle correction responses if the plan checker asks for revisions.
- We complete field verification. When construction reaches the right stage, we verify the installed insulation, windows, HVAC, and lighting match what the CF1R documents promised. We complete the CF2R installation certificates the inspector needs to see.
- We deliver the final CF3R certificate. After the final inspection passes, we file the CF3R form so the city closes your permit. You get a copy of every document in writing, and your guarantee from us covers the compliance work we performed.
Every one of these steps happens under The Kingswell Guarantee. The price is written before anything starts. The arrival window is defined. The job site is left cleaner than we found it. And if something is not right within 365 days, we come back and make it right, free of charge. That commitment is in writing on every project.

Title 24 Energy Compliance Pricing in Riverside
Title 24 compliance costs vary based on project size, system type, and how much correction your existing plans need. Here is what Riverside homeowners can expect to pay, based on projects we have completed in this market:
| Project Type | Typical Title 24 Compliance Cost | What Is Included |
|---|---|---|
| Garage conversion (under 500 sq ft) | $450 – $900 | Energy modeling, CF1R forms, CF2R verification, CF3R filing |
| Standard detached ADU (500 – 1,200 sq ft) | $700 – $1,500 | Full energy modeling, HERS verification coordination, all forms filed |
| Large ADU or addition (1,200+ sq ft) | $1,200 – $2,800 | Whole-building performance modeling, HERS testing, full documentation package |
| Compliance correction (city correction notice) | $300 – $800 | Review of filed documents, corrections, re-submittal to the city |
| HERS verification (if required) | $350 – $700 per visit | Field testing: duct leakage, airflow, envelope verification |
What drives the price? The square footage of conditioned space, the number of windows and their orientation, the type of HVAC system (mini-splits are common in Riverside ADUs and often simplify compliance), and whether the existing plans already include energy details or need reworked from scratch. Riverside summers are hot, and climate zone 10 puts real emphasis on cooling efficiency and window performance. Homes in La Sierra and Arlington Heights with older single-pane windows typically need more correction than newer builds.
We give every Title 24 quote in writing before any work begins. No estimate ranges that balloon later. No surprise add-ons when the inspector shows up. Call (831) 292-4191 for a free Title 24 estimate on your ADU, garage conversion, or addition.
What Happens If You Skip Title 24 Compliance
Some homeowners think Title 24 is a formality they can ignore. Here is what actually happens in Riverside when compliance is missing or incomplete:
- Your permit is not issued. The building department will not accept a permit application for a new ADU or addition without the CF1R documents. No documents, no permit, no construction.
- Your final inspection fails. Without completed CF2R and CF3R forms, the inspector cannot sign off. Your project sits unpermitted, which becomes a problem when you try to sell the home or refinance.
- Your homeowners insurance may not cover unpermitted work. This is a real risk. If an unpermitted ADU has a fire or electrical failure, the insurance company can deny the claim. We have seen this happen in Riverside more than once.
- Your home sale falls through. Riverside buyers are increasingly asking for permit records on ADUs before closing. An unpermitted or non-compliant ADU is a deal killer. Sellers are forced to either fix the compliance retroactively or drop the price.
- Retroactive compliance costs more. Fixing Title 24 after the fact means opening walls to verify insulation, potentially replacing non-compliant windows, and paying penalty fees. The cheap shortcut becomes the expensive problem.
We handle retroactive compliance for homeowners who bought a house with an unpermitted ADU or inherited a project from a contractor who never filed the energy forms. If that is your situation, call us. We will tell you honestly what it takes to bring the property into compliance and what it costs, in writing.
How Title 24 Works With Riverside’s Building Process
Title 24 is not a separate inspection. It is woven into the standard Riverside permit process, with three main forms that follow your project from design to final inspection:
- CF1R (Certificate of Compliance – Residential): The design-phase document. It states what insulation levels, window ratings, HVAC efficiency, and lighting requirements your project will meet. This is filed with your permit application.
- CF2R (Certificate of Installation): The construction-phase document. The contractor verifies that what was installed matches what the CF1R promised. The inspector checks this before signing off on rough framing and insulation.
- CF3R (Certificate of Verification): The final-phase document. Filed after the final inspection passes. The city uses this to close out your permit.
Riverside also participates in the statewide energy code updates that took effect January 1, 2023, which pushed for higher efficiency in new residential construction. Any ADU permitted after that date must meet the newer standards, which include more stringent envelope requirements and updated lighting controls. If you are working from older plans that were drawn before 2023, there is a good chance they do not comply with current code. We review every plan against current Riverside requirements before filing anything.
Will You Work With My Architect or Draftsperson?
Yes. Most of our Title 24 work happens alongside a homeowner’s existing designer, architect, or draftsperson. We receive the plans, run the compliance calculations, flag anything that will not pass, and coordinate corrections with the designer directly. You should not have to be the middleman translating between a designer and an energy consultant.
If you do not have plans yet, our ADU Design & Permitting in Riverside team can handle the full scope, from first sketch to final Title 24 filing. We work with established prefab ADU manufacturers like Abodu, Cover, and Dvele, and we know which of their models meet California Title 24 requirements out of the box. For site-built projects, we spec materials from brands like James Hardie that hold up under Riverside’s sun and simplify compliance.
How Kingswell Does Title 24 Differently
Title 24 compliance is a paperwork-heavy, detail-driven service. The way most companies handle it leaves homeowners frustrated: a cheap online calc that gets rejected by the city, a consultant who files the CF1R and disappears before the CF2R inspection, or a contractor who never mentions energy compliance until the final inspection fails.
The Kingswell Way works differently. We say the price before the work. We show up in the window we gave you. We leave the job site cleaner than we found it. We put the guarantee in writing. And we come back if it fails. Every Lodgewick technician on a Riverside job site is background-checked and uniformed, so you always know who is on your property.
Russ Delmar, the owner of Lodgewick ADU Riverside, has been doing ADU work under the Kingswell name since 2010. He has seen every Title 24 compliance scenario Riverside can throw at a build: corrections on garage conversions in Hawarden Hills, HERS testing on detached ADUs in Orangecrest, retroactive compliance on unpermitted units near UCR. That experience means we know what the Riverside plan checker looks for before we file, and we do not waste your time with documents that will bounce back.
FAQs – Title 24 Energy Compliance
How much does Title 24 compliance cost in Riverside?
Title 24 compliance in Riverside typically costs $450 to $2,800 depending on project size and scope. A garage conversion under 500 square feet runs $450 to $900 for full compliance, while a detached ADU from 500 to 1,200 square feet runs $700 to $1,500. Larger additions and whole-building models run higher. Every quote we give is in writing before work starts. Call (831) 292-4191 for an exact number on your project; estimates are free.
Can you fix Title 24 compliance after the city issued a correction notice?
Yes, we fix correction notices regularly. We review what was filed, identify what the city flagged, run corrected calculations, and resubmit the documents. Correction fixes typically cost $300 to $800 depending on the scope of the error. If your project was stalled, call us and we will tell you what it takes to get it moving again.
Is Title 24 the same as a HERS test?
No. Title 24 is the overall energy code, and a HERS test is one verification method sometimes required under Title 24. HERS (Home Energy Rating System) testing measures things like duct leakage and airflow, and it is used when your project takes the performance path instead of the prescriptive path. Not every project needs a HERS test, but if yours does, we coordinate the testing and filing. Call (831) 292-4191 to find out which path your project falls under.
Do I need Title 24 for a garage conversion in Riverside?
Yes. Any garage being converted to habitable living space in Riverside must meet current Title 24 energy standards. That includes insulation in the walls and ceiling, compliant windows, proper HVAC sizing, and the full CF1R, CF2R, and CF3R filing package. Garage conversions are a large part of what we do in Riverside, and we price compliance separately from construction so you know exactly what each piece costs.
What happens if my ADU was built without Title 24 compliance?
If your ADU was built without Title 24 compliance, the city will not close the permit, and you have an unpermitted living unit on your property. That creates problems with insurance, refinancing, and resale. We handle retroactive compliance by verifying what was installed, filing corrected forms, and coordinating with the Riverside building department. It costs more than doing it right the first time, but it is fixable. Call us and we will give you a written assessment of what your property needs.
