What goes into adding a sunroom to your house?
A sunroom addition in Fountain Valley is a new walled room built onto your house. It can be a screened or glassed room you use without heating or cooling, or a heated and cooled room that opens into the house as real living space.
Most people who call us have a patio they hardly use and a house that feels a room short. Some already have a slab or deck they'd like to build on, which is what our patio-to-sunroom conversion work covers. The price moves with the size of the room, what it stands on, and whether it's a closed-off room you use when the weather suits or a heated and cooled room open to the house. The schedule usually turns on any permit review and on HOA approval if you need it. Your written estimate spells out what's included, so you'll have a figure for your own room before you decide anything.
How do you know it's time to add a sunroom?
The patio sits empty
If the afternoon glare, the bugs or the wind keep everyone indoors, the space is there but you can't really use it. Every season you wait is another season that part of your yard goes to waste.
The house feels a room short
When the dining table has turned into a desk or guests end up on the couch, you usually need one more room, not a bigger house. A sunroom often adds that room without the upheaval of a move.
An old slab or cover shows wear
Cracks in the patio slab or a sagging cover usually mean the base needs a close look before anything goes on top of it. If you leave it, the damage tends to spread and the repair grows.
Two ways to build the room
Four season sunrooms
Worth a look if you'd like a room that's comfortable in July and January alike, heated, cooled and part of the house.
Three season sunrooms
A good fit if you want a bright, enclosed spot for the mild months that usually costs less to build.
How we build a sunroom addition
The first thing we settle with you is whether the new room stays closed off from the house or opens into it, because that choice decides how we build it and which windows it gets. Next I look over what the room will stand on, whether that's a slab, a deck or bare ground, since a room is only as sound as what's under it. From there our crew sets or repairs the base, frames the walls and roof, sets the windows and doors, ties the room into your house so it sheds water, and cleans up as we go.
If you want a room you'll use all year and walk straight into from the house, that's one of our four season sunrooms. If you'd sooner keep it separate and enjoy it when the weather is kind, one of our three season sunrooms is the plainer build.
Separate screened or glassed room
This suits you if you want shade, fresh air and fewer bugs without heating or cooling the space. It stays closed off from the house, so it's the lighter and simpler build.
Heated and cooled room open to the house
This suits you if you want another room you'll use every day of the year. It opens into the house and gets heating and cooling, so it's the fuller build and the one that adds true living space.

The owner comes out and stays
I measure and look over every job myself, and I work on site alongside our crew through the build. We've been in business since 2023, after my years on sunroom and patio jobs, and we're based in Fountain Valley and work in many cities around it across Orange County.
Fully licensed and insured
We're fully licensed and insured. In California, anyone doing work that needs a permit has to be licensed whatever the job costs, so please check the licence of any contractor you're considering with the state licensing board.
Fountain Valley plans prepared for you
The city wants structural calculations, energy documents, a soils report and any HOA approval with the plans for an addition. We prepare the plans, file them and meet the inspector, so you aren't left chasing paperwork.
What matters most on an addition is the base it sits on, so please ask for a visit and I'll look underneath before we talk about anything else.

Call or send a message
Ring (657) 329-2023 or send the form, and we'll get back to you to set a time for a visit that suits you.
I measure and look underneath
I come out, 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 you know what you're paying for before you agree to anything.
We handle the permit work
If you go ahead, we take care of the permit and the city paperwork. We'll tell you early what we need from you, such as approval from your HOA.
Build, then walk through together
I'm on site with our crew until the room is finished. Then we walk through it together so you can see every part before we call it done.
Common questions
How much does a sunroom addition cost in Orange County?
A sunroom in Orange County usually costs about $115 to $200 per square foot. Larger rooms that need a foundation and have heating and air conditioning sit at the higher end of that range. That's the area's usual price, not ours, and your written estimate spells out what's included for your own room.
Do I need a permit for a sunroom addition in Fountain Valley?
Check with the city's Building & Safety Division, which issues permits to enlarge or alter a building and whose list of exempt work names sheds and finish work but not sunrooms. The state Energy Code also sets energy, water efficiency and indoor air quality rules for additions to existing houses. When a permit is needed, we look after the filing.
How do I choose between a screened sunroom and a heated sunroom?
Choose by how you'll use it. A room walled with screen, thin plastic film, or glass or plastic panels and left without heating or cooling counts as a non-living space, while a room built to be heated and cooled and open to the house counts as living space. The living-space version needs windows that meet standards for keeping out air and water and for holding the temperature, so plan on windows built to that standard.
How much of a deposit can a contractor ask for on a sunroom in California?
California caps the down payment on a home improvement job at $1,000 or 10 percent of the contract price, whichever is less, and there's no exception for special-order materials. Your contract should also say in writing who will get the permits, and it must give a completion date.
How do I know how big a sunroom I can add on my Fountain Valley lot?
The city's yard rules set the limit. Your rear setback is 20% of the average lot depth or 25 feet, whichever is less, though a single-story attached addition can come within 10 feet of the rear property line if it's no wider than half the lot width. The rear yard must keep 1,000 square feet of open space, and everything on the lot together can cover no more than 60%, or 50% on lots of 10,000 square feet or more, so I measure your lot at the visit to see where the room fits.
How do I take care of a sunroom roof?
One maker's guide suggests inspecting the sunroom roof and gutters once a year. The same guide advises keeping activity on any roof, the sunroom's included, to what's needed. If something looks off up there, please give us a call rather than climbing on it.
