Covina houses and the yards behind them
Covina is a compact city in the East San Gabriel Valley, east of downtown Los Angeles, with freeways on most sides and a downtown that still runs along Citrus Avenue. On our jobs there we mostly see single-family houses on regular lots, a lot of them single-story with a concrete patio and an older patio cover out back, plus condos where the HOA has a say in anything on the outside. It's a short drive from our base in Chino, and we do the same work next door in West Covina and Pomona.
What's already out back moves the price more than anything, because a slab poured for a patio table isn't always ready to carry walls and a roof. The schedule turns on the paperwork, since some Covina addresses sit in county pockets and that decides which office reviews your room. I look at both at the estimate, and it all goes in writing.
Our services in Covina, CA
Plenty of Covina houses are single-story with yard behind them, so a sunroom addition is often the simplest way to gain a real room. We tie the new roof into your roofline and plan where the water runs off before anything goes up.
Most yards here already have a concrete patio, and the question is whether it was poured to hold a room or just a table. I check the slab's edges and thickness first, and if it can't carry a room we tell you and plan footings instead.
If you already like the patio you have and want it closed in, enclosed patio rooms keep the footprint and add walls, windows and a door. We check the posts and beam on the existing cover before we hang anything on them.
Older aluminum and wood patio covers are common behind Covina houses, and many are worn out by the time we see them. We replace them with a cover fastened properly at the house and pitched so rain runs away from your back door.
Some rooms out back were closed in years ago and now leak where they meet the house or get used as storage. We find where the water gets in, fix what the room sits on if it needs it, and redo the roof, glass or finish so it works as a room again.
If you want to sit outside without bugs and don't need glass, a screen room on your existing slab is the lighter and less costly choice. It still needs a sound base and a roof tied in right, so we check those the same way we would for a full sunroom.

What happens after you call us in Covina
Call us or send the form
You call or fill out the form, and we set a time for me to come to your house. It helps if you're home so you can show me how you want to use the room.
I measure and check the base
I measure the space, look at the slab, deck or cover the room would sit on and ask how you plan to use it. You get a written estimate that spells out what we'd build and what it sits on.
We handle the city side
Once you sign, we confirm whether your address goes to the City of Covina or Los Angeles County, take care of the paperwork that office asks for and keep you posted. Building starts once the permit is issued, so this step sets the start date.
We build and walk it together
My lead installer runs our own crew on site from layout through cleanup. When the room is done, I walk it with you and show you how it's built and where the water goes.
Covina sunroom questions answered
How do I check if my Covina address is in the city or LA County?
Run your address through the city's address lookup, because Covina has 11 county pockets inside it where Los Angeles County handles planning and building. If you're in one, LA County Public Works issues the permit, even if your water still comes from Covina Water. It's the first thing we look up on a Covina job, since it decides who reviews your room.
Do I need Planning approval to add a sunroom in Covina?
Yes, a sunroom at a City of Covina address goes through Planning before it gets a building permit. The city sends work that adds square feet, builds a new structure or changes the outside of the house to Planning first, then to Building & Safety, and a sunroom usually does all three. It isn't an over-the-counter express permit like a like-for-like re-roof, so expect a plan check, and we take care of the drawings and the site plan the city asks for.
How much does a sunroom cost in Covina?
The price comes down to the size of the room, the kind of room and what it sits on. A glass room you'll use year round costs more than a screen room, and the biggest swing is whether your slab can carry walls and a roof or needs footings or a new pour. How the roof ties into your house, any wiring and the Planning and plan check steps add to it, and your written estimate spells out each of those for your yard.
How do I check a sunroom contractor's license in California?
Ask for the license and look it up with the Contractors State License Board, the state office that licenses and regulates contractors. To pull a Covina building permit, a contractor has to show that state license card with its classification, photo ID, proof of workers' comp coverage and a current City of Covina business license. We're fully licensed and insured, and I'm glad to show you our paperwork at the estimate.
Can I add a sunroom to my condo in Covina?
Usually yes, if your HOA signs off, because a permit for work on a condo building's exterior or common area needs a letter of authorization signed by the HOA president. The city wants backing for that letter, such as HOA minutes, or it may consider sign-off from all the condo owners instead. Start on that early, since the permit waits on it.
How much can a contractor ask for as a down payment in California?
No more than $1,000 or 10 percent of the total contract price, whichever is less, under the state board's rules. After that, payments are listed in the contract and tied to work done or materials delivered, and the board says this covers all home improvement projects, sunrooms included. Look for that payment schedule in any contract before you sign it.
