Homes and back patios across Aliso Viejo
Most calls from Aliso Viejo are about the back of the house. It might be a covered patio that gets too much afternoon sun, a slab that could hold a room, or a sunroom put up years ago that nobody sits in anymore. The neighborhoods here are planned and well kept, many yards are tidy rather than large, and a good number of homes sit on ground that rises or falls from one street to the next. We see much the same in Irvine and Newport Beach, but every yard raises its own questions, and I'd rather answer them on your patio than guess from a photo.
The city's own design figures show what a room here has to stand up to. Its building department plans for rain falling as hard as 2 inches an hour, wind on open ground and earthquake design for seismic zones D and E, so we plan the gutters, the bracing and the way the room ties to its base around those.
How the city shapes a sunroom job in Aliso Viejo
In Aliso Viejo, permits come from the city's Building & Safety department. It handles building, electrical, mechanical and plumbing permits, and each one has its own inspections. Whether your room needs a permit, and which ones, is the city's call, not ours. A sunroom with lights and outlets usually means more than one permit and more than one inspection, so the schedule depends on those visits as much as on our crew. We prepare the plans, file them with the city and meet the inspector. We're fully licensed and insured. Before you hire anyone, it's fair to ask whether they've registered with the city, because its business registration application is where a business working here starts.
We're based in Fountain Valley and work in many cities around it across Orange County, Aliso Viejo among them. The Aliso Viejo Community Association looks after most of the parks and common ground here, and many homes also answer to a neighborhood association. If yours does, I'll tell you early that we need its approval before the work can go ahead. The price depends on the size of the room, the glass and roof you choose, and whether your slab or deck can carry a room as it stands or needs work first. The schedule depends on the permits and any association review. My written estimate spells out what's included, so you can see where the money goes before you decide.

Enclosed patio rooms
Many Aliso Viejo homes already have a covered patio out back that's too hot in the afternoon and too exposed in winter. We close it in as one of our enclosed patio rooms once we've confirmed the slab and the cover can carry walls and glass.
Patio cover installation
Smaller yards here often need shade more than another room. We put up a patio cover that sheds hard rain away from the house and is fastened to stay put when the wind picks up.
Four season sunrooms
If you want a room you can use in January as well as July, it needs insulated glass and a roof that holds the heat in. We build four season rooms that join the house properly, so they feel like part of it rather than a porch with windows.
Sunroom remodeling
We often find older sunrooms with foggy panels, tired framing or a roof that drips at the seams. We look underneath first, then replace what's worn so the room is comfortable to sit in again.
Deck-to-sunroom conversion
On lots that slope away from the house, a raised deck is sometimes the only flat spot for a room. We check the posts, beams and footings before anything else, because a deck built for chairs isn't always ready for walls and a roof.
Screen room installation
Some homeowners only want to sit out on summer evenings without the bugs. A screen room does that for less than a glass room, and we'll tell you plainly if it's all you need.
What happens after you call us about a room in Aliso Viejo
Call or send us a message
We get back to you to set a time that suits you. Please plan to be home for the visit, because how you'll use the room shapes what I recommend.
I measure and look underneath
I come out myself, measure, check what the room will stand on and ask how you plan to use it. Then I send a written estimate in plain words that spells out what's included, so there are no surprises in the price.
We handle the city paperwork
If you go ahead, we take care of the permit and the city paperwork. We work within the city's construction hours, Monday to Friday 7 a.m. to 8 p.m. and Saturday 8 a.m. to 8 p.m., with no work on Sundays or federal holidays.
We walk through it together
I'm on site with our crew until the room is finished. You don't need to be home every day, but please be there at the end so we can walk through the room together and answer your questions.
Common questions
How do I know if my sunroom project needs a Water Quality permit in Aliso Viejo?
The city's building permit application requires a Water Quality permit when a project disturbs 250 cubic feet or more of soil or hard surface. It also applies to 250 square feet of flat work like concrete or pavers, or to stockpiling dirt in front of the property. A new slab or digging for footings can reach those figures, so I check this when I measure, and if your job needs the permit we file it with the rest of the paperwork.
How long does it take to get a sunroom inspection in Aliso Viejo?
An inspection requested before 4 p.m. is set for the next business day unless another day is requested. Inspections are booked through the city's online Customer Self-Service Portal with an account, and cancellations go by phone to the Building Department at 949-425-2540 between 7:30 and 8:30 a.m. We meet the inspector on our jobs and keep you posted on the dates.
Who holds the permit for a sunroom built in Aliso Viejo?
The city issues the permit in the name of either the licensed contractor or the property owner, and that holder is responsible and liable for the construction. Because that matters, I'll go over with you whose name goes on it before anything is filed.
How much does a sunroom cost in Aliso Viejo?
The cost depends on the size of the room, the kind of room and what it has to stand on, so I give you a figure only after I've measured and looked underneath. A screen room or three season room on a sound slab costs less than a four season room with insulated glass and heating and cooling, and a new slab, footings or electrical work add to the price. Your written estimate lists each of these, so you can leave out what you don't need.
What does the city require for hauling away an old patio cover or sunroom in Aliso Viejo?
On a residential job, the city requires a Construction and Demolition permit when total waste is more than 3.4 pounds per square foot of construction area, and CR&R is the only hauler allowed to take waste out of the city. Tearing out an old cover or a worn sunroom first can push a job past that line. I look at what's coming out when I measure, so the hauling is in your estimate from the start.
What approvals does a sunroom need before the final inspection in Aliso Viejo?
Before the final inspection, a project may need sign-off from the city's planning and public works departments and from its crime prevention design review. Final approval may also be needed from the Orange County Fire Authority, the Orange County Health Department or Moulton Niguel Water District. As we prepare the plans, we work out which of these apply to your room.
