Sunroom additions in Loma Linda CA - a room that fits how you'll use it
Got a patio, slab or deck that sits empty most of the year? We turn it into a room you'll actually use.
What goes into adding a sunroom to your house?
A sunroom addition in Loma Linda encloses your patio or porch as a real room, anything from a screened room to a fully enclosed space that's heated and cooled. You get usable space off the back of the house without moving out of it.
Most people who call us have a covered patio, a slab or a deck they want to enclose. The price mostly comes down to the size of the room, whether it needs a new foundation and whether it's heated and cooled, since bigger rooms on a foundation with heating and air sit at the high end. The schedule turns on the decisions you make up front and on the city's plan check, and the written estimate I give you after seeing your house spells out what your room will take. If you're starting from a bare slab, our patio-to-sunroom conversion page covers that path.
How we build a sunroom addition
The first thing I settle with you is whether the room opens to the house or stays closed off, because that changes how it's built and how the city sees it. Under the industry's sunroom specification, a heated or cooled room open to the house counts as living space, and one sealed off with its own heating and cooling doesn't, so we decide that before anything gets drawn. The same specification has every sunroom follow the local code for ways out and emergency escape openings, so we lay out the doors and windows around that from the first drawing. From there we check the slab or deck, build up the foundation where it needs it, frame the walls and roof, set the windows and doors, then finish and clean up.
Most of the choice comes down to how you'll use the room. Three season sunrooms have no heating or cooling and use screens or uninsulated windows, which keeps the cost down and works well for spring and fall evenings. Four season sunrooms are heated and cooled with all-weather windows. If you want to sit in the room on a July afternoon here, that's the one I'd point you to, because a room without cooling gets hard to use by midday.
Sunroom additions in Loma Linda and the city's review
In Loma Linda, the city's Building and Safety Division plan-checks every proposed construction project, additions included, before it issues a building permit, so your sunroom gets reviewed on paper before we build anything. We put together the plans and paperwork, file them with the city and meet the inspector for each inspection. The city is also adopting CAL FIRE's updated fire hazard maps, which rate areas Moderate, High or Very High so building and fire safety requirements apply in the mapped zones. You can ask the city's building office which zone your home sits in.
We're based in Loma Linda and build in the cities around it, from Riverside and Fontana to Redlands, Yucaipa and Beaumont. The job looks much the same on additions in Redlands and Riverside, often an older covered patio on a slab that was never poured to carry walls, so I check the slab's edges and thickness before we plan anything on it.
How a sunroom addition works

I measure and look underneath

Common questions about sunroom additions
How much does a sunroom addition cost near Loma Linda?
A sunroom in nearby Riverside usually costs about $17,000 to $120,000 per project, going by Riverside figures. Larger rooms that need a foundation and come with heating and air conditioning land at the higher end, so a three season room on a sound slab usually comes in lower than a four season room on new footings. Your written estimate gives you the figure for your house.
Does Loma Linda review sunroom additions before you build?
Yes, the city checks the plans before it issues a permit, as covered above. During the work, its inspectors come out to check structural, fire, health and safety requirements, and we meet them on site each time.
Can I build a sunroom myself in California?
Yes, if you qualify as an owner-builder, since the state license board says owners improving existing structures on their own property, doing the work themselves or with their own employees paid in wages, may be exempt from licensing. Anyone you hire needs a Contractors State License Board license when the job needs a building permit or runs $1,000 or more in labor and materials, and they need it before they bid. If you go it alone, the city's permit applications page has an owner-builder packet.
Can a sunroom go on my existing deck?
Yes, the industry's sunroom specification allows any type of sunroom on a deck as long as the deck is built to the local building code. I look at the framing and footings on the first visit, and if the deck needs work to carry walls and a roof, that goes in the estimate. Our deck-to-sunroom conversion page goes into more detail.
How do I keep a sunroom in good shape?
Check the roof and gutters once a year and keep the door and window tracks clean inside and out, which is what one sunroom maker's care guide suggests. The same guide suggests a pure silicone spray to keep doors and windows sliding, since oil-based lubricants tend to attract dirt, and keeping the weep holes, the small drain openings in the frame, clear so water can get out.
What is the best way to choose between a screen room and a sunroom?
Start with whether you want the space treated as outdoors or as a room, because the industry specification treats a screen-only room as outdoor space unless the local code says otherwise. If you mainly want shade and fewer bugs, a screen room usually does the job, and if you want glass with heating and cooling, you're looking at a sunroom. We also handle screen room installation.
Why Loma Linda homeowners call Loma Linda Sunrooms & Patios for a sunroom addition
I come out to every job
I come out to look at every job myself, and our own crew does the building. The person who checked your slab is the one answering for the room.
A straight no on visit one
I'd rather tell you no on the first visit than sell you a room your deck or slab can't hold. Fixing a foundation or adding insulation after the fact costs you more than doing it up front.
Licensed and insured for additions
We're fully licensed and insured. An addition ties a new room onto your house, so that's the first thing worth asking any builder you're comparing.
Building patio rooms since 2021
I built patio covers and sunrooms when I was younger, then came back to the trade and started this business in 2021 because I didn't want to build halfway. Most of our calls come from homeowners in Loma Linda and nearby with a patio, slab or deck to enclose, and turning those into rooms people use is what we're known for.
On an addition, the foundation and the open-or-closed question matter more than anything you pick later, so let's look at both at your house. Call (909) 515-5048 or reach us through our contact page.
Pick the sunroom type that fits
Four season sunrooms
Go this way if you want the room comfortable through summer heat and cold winter nights, with heating, cooling and all-weather glass.
Three season sunrooms
A lighter, lower-cost room for the mild months, when you mostly want shade, fresh air and a place to sit outside the bugs.
