Three season sunrooms in Calabasas CA - a bright room made to fit your space

Building a sunroom in the Los Angeles area usually costs about $110 to $160 per square foot. That's a general figure for sunrooms of all kinds across the area, so treat it as a starting point and not a quote for your room. Your written estimate gives the number for your house.

No, a three season room is planned as a space kept apart from your home's heating and cooling. The sunroom industry's own specification treats a room like this, with glass or plastic openings and kept separate from the house, as space that isn't heated or cooled and isn't meant as regular living space. If you want a room you'll use like the rest of the house all year, an all season room with insulated walls and windows is the better fit, and I'll say so at the estimate.

Ask Calabasas Building and Safety, the city's contact for building permits. Its permit list names electrical, mechanical and plumbing work and doesn't name sunrooms, so whether your room needs one is a question for them about your project. We find out what the city or county asks at your address, take care of the permit paperwork when one is needed and keep you posted.

Pay in stages, with a down payment no larger than $1,000 or 10 percent of the total contract price, whichever is less. That cap comes from the Contractors State License Board, which licenses and regulates contractors in California, and later payments in the contract should follow work completed or materials delivered. We're licensed and fully insured.

They can, because where the room sits on your lot can bring city rules into the plan. If your property is in a high or very high zone on the latest fire hazard severity map, it may fall under a California Building Code chapter for those areas and defensible space requirements. The city's scenic corridor guidelines cover projects within 500 feet of Mulholland Highway, Las Virgenes Road, Old Topanga Canyon or the Ventura Freeway, or visible from one, and its oak tree guidelines make sure oaks and their habitat get proper consideration. We check these for your address here in Calabasas and look into the same kinds of rules in the cities around it.

Most are framed in aluminum, with vinyl and fiberglass also used, and one maker calls those materials maintenance-free. The roof is typically insulated aluminum panels, and thicker panels carry more insulation and can span farther. Under each window sits a kneewall, a short lower wall, built with a solid panel or tempered glass, which that maker says is stronger than plate glass and breaks into harmless pebble-like pieces.
