About Costa Mesa, CA

Most of our Costa Mesa calls come from owners of single-story stucco houses on regular backyard lots, many with a concrete patio and an aluminum or wood cover that's been there a long time. The city has plenty of shops and offices along its main roads, but the streets we work on are mostly quiet blocks of homes, a lot like what we see next door in Fountain Valley and Huntington Beach.

That means most jobs here are add-ons to a house that's already settled into its yard, so the first thing I look at is what your patio and back wall can carry.

Services in Costa Mesa, CA

  • Patio-to-sunroom conversion

    Most Costa Mesa backyards already have a concrete patio by the back door, and turning it into a closed room is one of the calls we get most here. We check the slab, take off the old cover and build walls, glass and a roof that tie into your house.

  • Patio enclosures

    If you want the patio sheltered from wind and dust but don't need a full room, an enclosure with screen or glass panels does the job for less. We fit it to your existing cover when that cover's in good shape and replace it when it isn't.

  • Custom sunrooms

    Stucco houses here come with all kinds of rooflines, and a kit room rarely lines up with every one of them. Our custom sunrooms are drawn to your wall height, roof pitch and the doors and windows you already have, so the room looks like it came with the house.

  • Four season sunrooms

    If you want a room you'll sit in on hot afternoons and cool evenings alike, a four season room with insulated walls, better glass and heating or cooling is the one to look at. I'll walk you through what that adds to the job, because it's a bigger build than an unheated room.

  • Three season sunrooms

    A lot of owners here mostly want a bright spot for mornings and weekends, and a three season room with lighter framing and no heating does that well. It costs less and goes up quicker, and the trade-off is that it runs warm or cool with the weather outside.

  • Patio cover installation

    Plenty of the aluminum covers on older Costa Mesa houses have sagged or rusted at the fasteners. We replace them with a new cover tied properly into the house, and we can frame it so walls go in later if you decide on a room.

What it takes to build a sunroom in Costa Mesa

Building permits in Costa Mesa come from the city's Building Safety Division, and when a room calls for one, that's where the plans go before we start. The city sends back applications that are missing anything, so we work out what it will ask for, put the drawings together, pull the permits and set up the inspections, and you're not chasing paperwork. Whoever you hire for this should hold a California contractor's license, and we're fully licensed and insured.

The price here mostly turns on the size of the room, whether it's heated or unheated, how much glass you want and whether the old slab and cover can stay. The schedule turns on the city's review and on how much of the old patio has to come out first, and your own figure comes from the written estimate I give you after I've seen the house. We drive in from Seal Beach for this work, and we build the same kinds of rooms in Irvine and up in Norwalk.

Costa Mesa, CA properties and local conditions

A lot of the patios we look at in Costa Mesa were poured as a place for a grill and a few chairs, not as a floor for a room. I check the slab for cracks, slope and thickness before we draw anything, because walls and glass need a solid, level edge to sit on, and when the slab can't do it we usually add footings along the outside. The old cover tends to come off too, since most weren't framed to hold up a closed roof, and where the new roof meets your stucco wall is where we take the most care sealing the joint.

Patios that face west or south can take a lot of afternoon sun, which is why people want a room there and also why a room with the wrong glass gets too hot to sit in. We talk through glass, roof panels and heated versus unheated so the room is comfortable at the hours you'll actually use it.

What happens after you call us about a Costa Mesa sunroom

  1. Call or send the form

    Call (562) 200-7987 or use the form, and we'll pick a time for me to come out. It helps if you're home for the visit, since I'll want to hear how you plan to use the room.

  2. I look and sketch options

    I look at the house, the patio and the back wall, and I sketch the options with you right there. You get a free written estimate afterward, so you know what each choice costs before you decide anything.

  3. We file the permit paperwork

    We prepare the plans the city asks for, file them and set up the inspections. The city sets the pace of its review, so we send a complete set the first time to keep it from coming back.

  4. We build, then walk through

    Our crew and I build the room, and I'm on site working alongside them. When it's done, I walk the room with you and show you how to look after the glass, seals and tracks.

Frequently asked questions

Do I need a licensed contractor to build a sunroom in Costa Mesa?

Almost always, yes, because California's Contractors State License Board requires a license whenever a job needs a building permit, uses employees or totals $1,000 or more in labor and materials. A sunroom runs past $1,000 on its own, and the state doesn't allow splitting a bigger job into smaller contracts to get under that line.

How do I apply for a building permit in Costa Mesa?

You apply through TESSA, the city's online permit system, where all the application information is entered and the plans are uploaded. The city ignores paper forms and returns incomplete applications, which is why we handle the filing ourselves when you hire us.

Can I get an Insta-Permit for a sunroom in Costa Mesa?

No, the city's Insta-Permits cover residential HVAC, re-pipe, water heater, EV charger, panel upgrade and re-roof work, and sunrooms and patio enclosures aren't on that list. The list doesn't tell you whether your room needs a full permit, so the place to ask is Building Safety at (714) 754-5273, and it's a call we make for you once the design is set.

What happens if a contractor works without a license in California?

A first offense for contracting without a license is usually a misdemeanor, a lesser crime that can carry up to six months in jail, a $500 fine or both. The state can add an administrative fine of $200 to $15,000, so it's worth checking the license before you sign anything.

How much does a sunroom cost in Costa Mesa?

The price comes down to the room's size, whether it's heated or unheated, how much glass you want and whether your slab and back wall can be used as they are. A four season room costs more than a three season one, and a slab that needs new footings adds to it, so if you're torn between heated and not, I'll price both on your estimate.

How long does it take to get a sunroom built in Costa Mesa?

Most of the wait usually comes before the build, while the plans go through the city, and the time on site is the shorter part. We can't set the city's pace, so we have the plans complete and the materials ordered so the crew can start soon after approval, and a room that keeps the existing slab goes up faster than one that needs new footings.
