What does sunroom design actually cover?
Sunroom design in Hacienda Heights is where we draw your room for your house, with its exact size, where it sits and how its floor is built, so the permit office and our crew work from the same plan.
Most people who call us want more use out of a patio or deck, and some have a sunroom that never worked the way they'd hoped. The price moves with the room's size, whether it's heated and open to the house, and whether what it sits on can hold it as is. The schedule mostly turns on the permit review and on any work the base needs first. If you're starting from a slab out back, our patio-to-sunroom conversion page covers that side, and the written estimate after my visit gives you the figure for your house.
How do you know it's time to plan a sunroom properly?
Patio too hot to use
You've got a covered patio or slab out back that nobody sits on after lunch because the sun hits it full on, and a patio umbrella can only do so much. That usually means the spot is fine and the shade isn't, and a room built there without planning for it just traps the heat behind glass.
A sunroom that never feels right
It's too warm by afternoon, a door sticks, or you just don't go in there much. Often the room went on the wrong wall or on a base that wasn't ready for it, and fixing a built room costs more than drawing it right the first time.
A quote with no drawings
Someone gave you a number for a sunroom without drawing it or looking at what's under the patio. That usually means nobody has checked what the room will sit on, and since the permit office wants drawings anyway, the number may not survive the first real question.
How our sunroom design works
I start by looking at what the room will sit on, whether that's a patio slab, a deck or bare yard, because a sunroom is mostly glass resting on whatever is under it. Then I measure, ask how you plan to use the room, and work out which way the glass faces and what shades it, since that decides how warm the room runs. We draw the room for your house, down to its exact size, where it sits and how its floor is built, and those drawings are what we take in for the permit. My crew and I build from that same set, so the room in your yard matches the one on paper.
Design is the first part of most jobs we do. If you want a low-upkeep frame, we'll draw the room around one of our vinyl sunrooms, and if it's a full new part of the house, the drawings carry straight into our sunroom additions work.
Heated room open to the house
This suits you if you want another living room you can use any time of year, with no door between it and the kitchen. Expect more planning on the glass and doors, because this room has more to live up to.
Closed-off room without heating
This suits you if you want a bright place to sit most of the year and don't mind shutting a door between it and the house. It's a simpler room to plan, and it usually comes in at a lighter price.
Room on your existing patio or deck
This suits you if the slab or deck is already where you'd sit anyway. Whether it can carry a room as is decides how much work comes before the walls go up.

(626) 269-6285Sunroom design and permits in Hacienda Heights
If your house is in unincorporated LA County, LA County Public Works issues the building permit. The county's addition and alteration list names adding a new room but doesn't name sunrooms, so the list alone doesn't settle what your room needs, and homes outside the county's jurisdiction may go through another office. The county asks owners to call or email their local office, which you can find through its Service Locator, about what a project requires. We look up which office handles your address, and when the job needs a permit, we take care of the paperwork and work through the inspections with you. While the drawings are still on paper, it's also worth entering your address in the State Fire Marshal's fire hazard severity zone map to see where your property falls.
Most of what we're asked to design here starts as a patio slab or an older deck behind the house, and plenty of those were built for a barbecue, not a glass room, so the design starts with what's underneath. We're based in Hacienda Heights and build in a lot of the cities around it, and we see the same backyards on jobs in Whittier and La Puente. If you don't see your city listed, call and ask.

Frequently asked questions
How much does a sunroom cost near Los Angeles?
A sunroom in the Los Angeles area usually costs about $23,000 to $66,000 for 200 square feet, and that's the market's range, not our price. Where your room lands depends on its size, whether it's heated and open to the house, and what it sits on. The written estimate after our visit gives you the number for your house.
Can an unlicensed designer draw my sunroom plans in California?
Often, yes. The California Energy Commission says state law lets unlicensed designers prepare design documents for wood-framed single-family homes no more than two stories high, not counting a basement, so a licensed design professional isn't always required. One sunroom maker's installer training says the homeowner or a hired drawing service, such as a local designer or the maker, draws those job drawings, and we draw the rooms we build.
Should my sunroom in Hacienda Heights be heated and open to the house?
If you want to use it like any other room every day of the year, yes, but it's the bigger design job. Under the industry's sunroom specification, a room that's heated or cooled and open to the house counts as habitable, conditioned space, and its windows and doors have to meet added air, water and thermal rules. A room kept closed off from the house without heating or cooling asks less of the design, and I'll ask how you plan to use it before we pick.
What is a plan check in LA County?
A plan check is the county's review of your project plans by experts, against safety, building and environmental standards. For a sunroom, the drawings from the design are what they review, which is why the size and placement need to be right before they go in.
What is the best way to keep a sunroom cool in Southern California?
Put the glass on the north side where you can, and shade the south side well. That's U.S. Department of Energy guidance for warm climates, and it adds that landscaping, overhangs, shutters and solar window screens cut the heat coming through glass in full sun. In a design, that means deciding which wall the room goes on and what shades it before any glass is ordered.
How do I take care of a sunroom once it's built?
Have the roof and gutters looked over once a year, and keep the weep holes, the small openings that let water drain, clear. That's from one sunroom company's owner guide, which also suggests pure silicone spray on door and window tracks instead of an oil-based lubricant, since oil tends to pull in dirt. Five minutes with the spray can beats a sticky door all summer.
