 FAQs

  • Yes, most sunrooms in California need a solid foundation to support the walls, roof, and glass. The most common base is a concrete slab, but some designs use a raised deck or a small crawl space if possible. The California Residential Code (CRC) provides the rules for stability, load support, and proper footing for sunroom additions.

    You can trust our team to know all the details of California’s local code for sunrooms. We will make sure everything is handled for you.


  • Yes. In California, a sunroom counts as a structural addition, so it needs a building permit under the California Residential Code (CRC). The state requires review of foundation details, framing, electrical work, and overall safety before construction starts.

  • In some cases, a sunroom in California can be included in the square footage if it is a fully conditioned space. The sunroom must have the same heating and cooling as the rest of the house, be completely enclosed, and follow the energy and structural requirements in the California Residential Code and Title 24 energy standards.

    If the sunroom has its own climate control or does not meet these requirements, appraisers in California might list it as extra living space but not count it in the official square footage. 

  • A conservatory is typically made almost entirely of glass, including the roof. This design lets in a lot of natural light but can also cause the room to heat up quickly, which matters in many areas of the state. In contrast, a sunroom usually has a solid or insulated roof and fewer glass panels, making it easier to control the temperature and keep the space comfortable throughout the year.

  • Sunroom prices in California are usually higher than the national average. This is due to state energy rules, building codes, and local labor costs. The final price depends on the size, type of glass, insulation, and how finished the room is.

    For a 20x20 sunroom, which is about 400 square feet:

    Most 20x20 sunroom projects cost between $70,000 and $130,000. If you want the range topping Four Season sunrooms with insulated roofs and energy-rated glass are usually at the higher end of this range.

    For a 12x12 sunroom, which is about 144 square feet:

    A typical 12x12 sunroom costs between $25,000 and $55,000. Three-season rooms are usually at the lower end, while fully conditioned rooms built to Title 24 standards are at the higher end.
