Short answer: A Title 24 report for a Los Angeles project is the energy compliance document that goes into your permit set. It shows the design meets California's Energy Code for the climate zone of your address. Title24Comply prepares it online from your plans, starting at $199 for ADUs, and typically delivers in 2–3 business days.
Los Angeles is California's largest city. Its many neighborhoods see steady ADU, addition, remodel and low-rise multifamily work.
Climate Zones in Los Angeles
Los Angeles covers more than one climate zone. Much of the city is in Climate Zone 9, a warm inland zone that includes the San Fernando Valley, where summers are hot. For projects in Zone 9, the Title 24 report has to deal with high cooling loads, the 2025 code's emphasis on heat pumps, and window glazing that suits strong sun exposure.
Because the city stretches from the coast to the valleys, the zone for your project depends on its exact address or ZIP code, not just the words "Los Angeles." We confirm the zone from your address before modeling. See Zone 9 Title 24 requirements or the full climate zone overview.
Title 24 Projects We Prepare in Los Angeles
We prepare Title 24 reports for all common residential project types in Los Angeles:
- New single-family home construction
- Room additions of any size
- ADUs and Junior ADUs including garage conversions
- Remodels and alterations affecting insulation, windows, or mechanical systems
- Multifamily duplexes, triplexes, and fourplexes
- HVAC replacement projects
- Window replacement projects
ADUs and garage conversions
ADUs are one of the most common permit types in Los Angeles. Many single-family lots have room for a detached backyard unit, and turning an existing garage into living space is a popular route. Every new conditioned ADU needs its own energy compliance, and a garage conversion counts as newly conditioned space even when the walls are already standing. Our Los Angeles ADU Title 24 guide covers the details, and garage conversion Title 24 reports explains how conversions are modeled.
Additions, new homes and alterations
Room and second-story additions are often modeled together with the existing house under the performance method. New homes also have to address solar PV and electric-ready measures. Alterations are usually smaller jobs, such as swapping an HVAC system or replacing windows, but depending on scope they can still trigger Title 24. See HVAC replacement and window replacement requirements.
Submitting Your Title 24 Report in Los Angeles
Projects within Los Angeles city limits are permitted through the Los Angeles Department of Building and Safety (LADBS). We format every report for LADBS submission. For submittal and plan check context, see our Los Angeles building department guide. Many addresses with an "LA" mailing address are actually in separate cities or unincorporated county areas. Check which jurisdiction issues your permit, because it may not be LADBS.
If plan check comes back with energy-related comments, two revisions are included. See handling plan check comments.

Frequently Asked Questions
What climate zone is Los Angeles in?
Much of Los Angeles is in Climate Zone 9, but the city spans more than one zone. The exact zone for your project comes from its address or ZIP code, and it is listed on the report.
Do I need a Title 24 report for an ADU in Los Angeles?
New conditioned ADUs, including garage conversions, generally need Title 24 energy compliance as part of the building permit. Your building department makes the final call on scope. See ADU energy compliance.
Can you prepare a report for an address outside LA city limits?
Yes. We prepare reports for any California jurisdiction. The energy code is the same statewide, and the report is submitted to whichever building department issues your permit.
Will a HERS rater need to visit my Los Angeles project?
If the report flags items for field verification, such as duct leakage or refrigerant charge, a HERS (ECC) rater tests them after installation. See HERS raters and Title 24.
