Residential Alterations & Title 24 Compliance in California

Understanding Title 24 California Residential Alterations

Title 24 of the California Code of Regulations, also known as the California Building Standards Code, sets strict energy efficiency requirements for new construction and building alterations. If you’re planning a residential alteration, you must comply with these energy standards to ensure your project meets the California Energy Commission (CEC) regulations.

Our team specializes in ECC Title 24 Reports to help homeowners, contractors, and builders navigate compliance efficiently. Whether you’re replacing windows, upgrading lighting, or modifying your HVAC system, we provide expert guidance and required documentation to streamline the approval process.

Key Areas of Focus for Title 24 Compliance

Building Envelope

The building envelope includes walls, roofs, windows, and doors. Title 24 regulations require these components to meet strict thermal performance standards, ensuring that homes maintain energy efficiency.

Window Replacements & Title 24 Compliance:
If you’re replacing windows as part of a Title 24 California residential alteration, your new windows must meet specific energy efficiency requirements, including:

  • Low U-Factor: Ensures improved insulation. Beautiful two-story house with illuminated windows and garage at dusk.

  • Solar Heat Gain Coefficient (SHGC): Helps reduce heat transfer into the home.

Our experts will assess your project, recommend energy-efficient windows, and oversee installation to guarantee compliance with ECC Title 24 Reports.

Lighting Requirements

Title 24 mandates that all residential lighting systems use high-efficacy fixtures and advanced lighting controls. This includes:

  • Energy-efficient LED fixtures

  • Occupancy sensors & dimmers to reduce energy waste

  • Automatic lighting controls for improved efficiency

We help homeowners integrate Title 24-compliant lighting solutions that enhance energy savings and meet regulatory standards.

HVAC System Upgrades

Heating, ventilation, and air conditioning (HVAC) systems are a major focus of Title 24 compliance. Energy efficiency requirements for HVAC systems include:

  • High-efficiency furnaces, air conditioners, and heat pumps

  • Duct insulation to minimize heat loss

  • Duct leakage limits to prevent energy waste

Ensuring your HVAC upgrades comply with ECC Title 24 Reports will improve indoor comfort and lower energy costs.

Insulation & Energy Efficiency

To maintain energy efficiency, the California Energy Commission requires residential alterations to have proper insulation. Adding insulation to walls, roofs, and floors helps reduce heat transfer and optimize indoor temperature control. Additionally, installing energy-efficient windows and doors further enhances compliance.
