Who Needs a Title 24 Report?

Many property owners, builders, and investors don’t realize that a Title 24 Report is not just for new homes. In reality, a wide range of construction projects in California require a Title 24 energy compliance report before permits can be approved.

If your project affects how a building uses energy, there is a strong chance you fall into the category of people who need one.

Projects That Require a Title 24 Report

You will typically need a Title 24 report if your project involves any of the following:

• New residential construction
• New commercial construction
• Room additions or floor area expansions
• Garage conversions or ADU construction
• Tenant improvements in commercial spaces
• Window replacements or exterior door changes
• New HVAC system installations or replacements
• Building envelope changes such as insulation upgrades

Even smaller remodels may require a Title 24 report if they impact energy-related components like walls, roofs, or heating and cooling equipment.

Why Title 24 Reports Are Required

California enforces Title 24 to ensure that buildings meet strict energy efficiency standards. These standards reduce long-term energy usage, lower operating costs, and support statewide environmental goals.

The report verifies that your project’s design meets minimum requirements for:

• Insulation performance
• HVAC efficiency
• Window and glazing performance
• Ventilation systems
• Overall building energy performance

Without a Title 24 report, local building departments will not approve your permit.

Do Small Remodels Need a Title 24 Report?

Not every remodel requires a Title 24 report — but many do.

You may need one if your remodel includes:

• Replacing more than 50% of your windows
• Upgrading or relocating HVAC systems
• Removing or replacing interior or exterior walls
• Altering insulation or ceiling assemblies

Even if your project seems minor, it’s always best to confirm with a compliance professional before submitting plans.

Who Should Request the Report?

The Title 24 report can be ordered by:

• Homeowners
• Real estate investors
• General contractors
• Architects and designers
• Developers and builders

Whoever submits the building plans is usually responsible for ensuring the report is included in the permit package.

What Information Is Needed to Get Started?

To generate a Title 24 report, the following information is usually required:

• Architectural drawings
• Mechanical and HVAC schedules
• Window and door specifications
• Floor area calculations
• Project address and scope

Providing accurate information from the start helps avoid corrections and resubmittals.
