Sunroom additions in Rossmoor CA - a room planned for how you'll really use it
Patio too hot, too buggy or too exposed to use? We build a sunroom onto your house that keeps the rain out where it joins.
What does it take to add a sunroom to a Rossmoor house?
A sunroom addition in Rossmoor builds an enclosed room onto the back or side of your house, with its own footings or slab, framing, roof and glass, so you get a room full of daylight that stays out of the wind and the bugs.
Most people who call us have a patio they hardly use, or a house that needs one more bright room, and they want to understand their choices before they spend anything. The price moves mostly with the size of the room, whether it stays unheated or gets heating and cooling, the glass and insulation you pick, how the new roof ties into yours and whether we need new footings or can build on what's there. The schedule usually turns on the permit office's review of the plans and on how long windows and panels take to arrive, and the estimate spells out your own figures line by line. If all you want is shade over the patio, a patio cover may be enough.
How we build a sunroom addition
I start where the new room meets your house, because that's where the roof ties in and where water tries to get in. I look at that wall and roofline first, and we plan the framing and flashing, the metal and membrane that turn rain away from the seams, around what I find. From there our crew sets the footings or readies the slab or deck the room will sit on, then frames the walls so the weight carries down to the foundation. After that we tie the roof in, flash the seams and set the glass, flooring and any wiring the room needs. I check the work at each stage as it goes, not only at the end.
The bigger choice is how you'll use the room, and it's worth settling before anything is drawn. A three season sunroom is a screened or glassed room left unheated, good for mild months and evenings out back. A four season sunroom is heated or cooled and open to the house, so it counts as living space, and its windows have to stop air leaks and water and hold in heat. I'd rather spend extra time on that choice, because glass and insulation are easiest to get right before we build.

The owner comes out to estimate
I started this business in Rossmoor in 2023 after growing up on my dad's patio room jobs, and I come out to look at your house and do the estimate myself. Our own crew does the building while I check the work along the way, so the person who wrote down your answers is the one watching the room go up.
Fully licensed and insured in California
We're fully licensed and insured. A sunroom that needs footings or ties into your roof is structural work, and the state licensing board says a residential remodeling contractor can't contract for structural changes to load-bearing parts of a house, so ask any builder how their license covers that part of your job.
Rossmoor-based, permit office checked first
We're based in Rossmoor and work in many of the cities around it, from Long Beach to Irvine. Before we draw anything, I check which office covers your address, so the plans go to the right place the first time.
The wall where the room meets your house decides most of the plan, so send us photos of it with a note on whether you want heating or cooling, or call (562) 488-9164.

Ideas for a sunroom addition
Questions before you book a sunroom addition
How much does a sunroom addition cost near Rossmoor?
A sunroom addition in the Los Angeles area usually costs about $22,000 to $67,000 per job, and that's the going range in the area, not our price. Where your room lands depends on its size, whether it's a screened room or a heated one open to the house, the glass and how much footing and roof work your house needs. I'll write your own figure out item by item at the estimate.
Do I need a permit for a sunroom addition in Rossmoor?
Most likely, because building additions typically need permits in unincorporated Orange County, where OC Development Services handles them. The county's permit list names patios and decks but not sunrooms, so that office is the place to confirm what your room needs. It offers over-the-counter or regular plan check, a review of the drawings, and it does the inspections. When the work needs a permit, we take care of the application and meet the inspector.
Does a heated sunroom have to meet California's Energy Code?
Yes, the state Energy Code applies to additions, and a sunroom that gets heating or cooling has to meet the rules for an addition. That's why I ask about heating and cooling on the first visit, since the answer tells us which energy rules the room has to meet before we choose glass and insulation.
How much can a contractor ask for up front on a sunroom in California?
In California, the down payment on a home improvement job can't be more than $1,000 or 10 percent of the contract price, whichever is less, and that holds even when materials are special-ordered for your room. The state also requires a written contract for any home improvement job over $500 that tells you of your right to cancel. If the plans change during the build, that change has to be in writing too.
How long does a sunroom addition take to build?
The schedule usually turns on the steps before building, the permit review and the order for glass and panels, more than on the framing itself. A heated room often takes more planning because its windows and insulation have to meet the energy rules. Once I've seen your wall and roofline, I'll walk you through the order of the steps.
How do I take care of a sunroom once it's built?
One sunroom maker's guide suggests checking the roof and gutters once a year and keeping the weep holes, the small drain openings, clear so water can get out. The same guide suggests a pure silicone spray on door and window tracks, since oil-based lubricants tend to attract dirt.
