Are you thinking about converting your garage into a secondary dwelling unit (also known as an accessory dwelling unit or ADU)? If so, you’ll need to make sure that your project meets the energy efficiency standards set by Title 24 of the California Code of Regulations.

Title 24 requirements is a set of rules that all new construction and major renovations in California must follow. Its goal is to reduce the amount of energy that buildings use, which helps to save money on utilities and protect the environment.

So, what do you need to know about Title 24 requirements if you’re planning a garage conversion ADU? Here are the basics:

  1. Title 24 applies to ADUs: Whether you’re building a new ADU or converting an existing space like a garage, your project will need to meet the energy efficiency standards set by Title 24. This means that you’ll need to make sure your plans are reviewed and approved by a certified energy analyst or engineer.
  2. There are different requirements for different climates: Title 24 requirements are different depending on where you live in California. This is because the energy efficiency needs of buildings vary depending on the local climate. Make sure you know the requirements for the climate zone where your ADU is located.
  3. You’ll need to get a building permit: In order to get a building permit for your ADU, you’ll need to show that your plans meet the requirements of Title 24. This means that you’ll need to have your plans reviewed and approved by a certified energy analyst or engineer.
  4. There are resources available to help you: If you’re not sure where to start with Title 24 compliance, don’t worry! The California Energy Commission has a variety of resources and tools to help homeowners understand and comply with the requirements. These resources include the Title 24 Energy Standards, the Title 24 Energy Compliance Manual, and the Title 24 Compliance Software.

By following the Title 24 requirements for your garage conversion ADU, you can help ensure that your project is energy efficient and cost-effective. Plus, you’ll be doing your part to protect the environment!

Title 24 is the California Building Standards Code that outlines the energy efficiency requirements for new construction and major renovations in the state. One specific area that Title 24 covers is the requirements for Accessory Dwelling Units (ADUs), which are small, self-contained units that are built on the same lot as a single-family home. These units can be used as a separate living space for family members, a rental property, or a home office.

To comply with Title 24 requirements , ADUs must meet certain energy efficiency standards, including requirements for insulation, windows, and heating and cooling systems. These requirements are designed to reduce energy consumption and greenhouse gas emissions, and to make the ADU more comfortable and affordable to live in.

One key requirement for ADUs under Title 24 is that they must have sufficient insulation to meet the minimum thermal resistance values for the climate zone in which they are located. This is important because proper insulation helps to keep the ADU warm in the winter and cool in the summer, reducing the need for heating and air conditioning. Title 24 specifies the minimum R-values for various types of insulation, such as fiberglass, cellulose, and spray foam, based on the climate zone and the type of construction.

Another requirement under Title 24 is that ADUs must have windows that meet certain energy efficiency standards. This includes requirements for the type of glazing, the U-factor (a measure of how well the window insulates), and the solar heat gain coefficient (a measure of how much solar heat is transmitted through the window). Title 24 specifies different requirements for different climate zones, as well as different requirements for different types of windows (such as skylights and sliding doors).

In addition to insulation and windows, Title 24 also has requirements for the heating and cooling systems used in ADUs. These requirements vary based on the size of the unit and the type of system, but generally, ADUs must have systems that meet minimum efficiency standards. This may include the use of high-efficiency furnaces, boilers, and air conditioners, as well as the use of energy-recovery ventilators and programmable thermostats.

Overall, the Title 24 requirements for ADUs are designed to promote energy efficiency and reduce greenhouse gas emissions. By complying with these requirements, homeowners can help to create more sustainable and comfortable living spaces, while also potentially saving money on energy costs. While the process of designing and building an ADU can be complex, the benefits of having a separate living space or rental property can be well worth the effort.
