If you are planning to build an Accessory Dwelling Unit (ADU) in California, you may be asking, "Do I need a Title 24 report for my ADU?" In most cases, the answer is yes. California requires many ADU projects to comply with Title 24 energy standards before receiving building approval.
What Is a Title 24 Report for an ADU?
A Title 24 report for an ADU is an energy compliance document required by California building departments to verify that a new residential structure meets the state's energy efficiency standards.
The report analyzes different aspects of your ADU design, including:
Building size and layout
Insulation levels
Windows and doors
Heating and cooling systems
Water heating systems
Lighting requirements
Solar energy requirements (when applicable)
Overall energy performance
The goal of a Title 24 report is to ensure that new buildings use energy efficiently while reducing long-term energy costs for homeowners
Is Title 24 Required for an ADU in California?
Yes, most newly constructed ADUs in California require Title 24 energy compliance documentation before permits can be approved.
California's Energy Code applies to many types of residential construction, including:
Detached ADUs
Attached ADUs
Garage conversions
New additions
Newly built residential units
Your local building department will typically require a Title 24 report as part of the permit submission process.
Because requirements can vary depending on your project details and location, it is important to complete your energy calculations before finalizing your construction plans.
When Should I Get a Title 24 Report for My ADU?
The best time to complete your ADU Title 24 calculations is during the design and planning phase, before construction begins.
Getting your report early allows your architect, designer, or contractor to make adjustments if your project does not meet California energy standards.
Waiting until the permit stage may lead to:
Design changes
Additional project costs
Permit delays
Construction timeline setbacks
A completed Title 24 report helps ensure your plans are ready for submission.
What Information Is Needed for an ADU Title 24 Report?
To complete accurate Title 24 energy calculations for an ADU, your energy consultant will typically need:
Architectural floor plans
Site plans
Window and door information
HVAC system specifications
Water heater details
Insulation information
Construction details
Location of the project
Providing complete project information helps create an accurate energy compliance report.
Do Garage Conversion ADUs Need a Title 24 Report?
Many homeowners ask whether a garage conversion ADU requires Title 24 compliance.
The answer depends on the scope of the conversion. While some existing building elements may qualify for exemptions or special requirements, many garage conversions still require energy documentation to demonstrate compliance with California's Energy Code.
A professional Title 24 consultant can review your project details and determine what documentation is required.
How Much Does a Title 24 Report Cost for an ADU?
The cost of a Title 24 report for an ADU depends on several factors, including:
Project size
Complexity of the design
Location
Type of construction
Required calculations
Many standard ADU projects have straightforward energy compliance requirements, making them a cost-effective service to complete early in the building process.
