What goes into a custom sunroom in Manhattan Beach?
A custom sunroom is a room we add to your house in Manhattan Beach, built on a slab or deck and planned around how you'll use it, so outdoor space you rarely sit in becomes a room you'll use most of the year.
Most people who call Manhattan Beach Sunrooms & Patios have a patio or deck that's too sunny in the afternoon or too breezy in the evening, and they'd like that patio turned into a real room. The price moves with the size of the room, the roof and glass you choose, how much shading and insulation goes in, and whether the base underneath can stay or needs replacing. The schedule turns mostly on the city's permit and on any base work that has to come first, and your written estimate lays out the room we plan together for your house. We're based in Manhattan Beach and work across the South Bay and the cities around it.
How we plan and build a custom sunroom
We start with what the room will sit on, because a sunroom is only as steady as the slab or deck under it, and if yours is worn we say so early so a new base goes into the plan instead of turning up as a surprise. Then we plan shade, fresh air and insulation together, since those three decide whether the room is pleasant to sit in, and we settle the roof, the glass and where the windows open before anything is ordered. On the build, our crew readies the base, frames the walls and roof, sets the glass, seals and insulates, and finishes the trim inside and out before we clean up.
If you'd like to know what the build itself looks like from base to roof, our sunroom construction page walks through it. If you already have a sunroom that runs hot or feels tired, sunroom remodeling can often put it right without starting over.
Building on the base you have
This suits a patio or deck that's level, solid and in very good shape, because keeping it saves the cost and time of a new one. I'll only suggest it after I've looked at it closely.
Starting on a new slab or deck
This suits a patio that's cracked or sinking, or a deck that's seen better years, because a new base gives the room a sound footing. It adds to the budget, which is why I bring it up at the first visit.
Custom sunroom permits and rules in Manhattan Beach
The City of Manhattan Beach requires a coastal permit for projects inside its Coastal Zone unless the project is exempt or excluded, and no work or inspections can happen until a permit is approved and issued. That means your start date follows the permit, not our calendar, and whether your sunroom needs a coastal permit isn't settled until someone looks at your address and the project. Before work starts, we check with the city about what your job needs, then prepare and file the paperwork for any permits it calls for.
A sunroom you heat or cool adds to your home's living space, and the city requires additions that grow a home's heated or cooled area, or its size, to recycle a set share of their construction waste, so we plan the cleanup around that from the start. Most patios and decks we look at here have spent years out in the weather, and we see the same on jobs in Hermosa Beach and Redondo Beach, so checking the base is where the first visit starts.
Why Manhattan Beach homeowners call Manhattan Beach Sunrooms & Patios for custom sunrooms
I measure and plan every room
I come out to every job myself to measure and plan the room with you, and our own crew does the building. The room you agreed to is the room we build, without handing you off to someone you've never met.
Licensed for a job this size
We're licensed and fully insured. In California, a job of $500 or more in labor and materials calls for a contractor licensed by the Contractors State License Board, and a sunroom runs well past that.
Started in Manhattan Beach in 2023
I learned this trade building patio covers and enclosures and started this business here in 2023, so the city's coastal permit step is part of how we plan every job here. I'd rather you understand what you're getting before you sign anything than hurry you into a decision.

Frequently asked questions
What does a custom sunroom cost in Manhattan Beach?
A sunroom addition in Los Angeles usually costs about $23,000 to $66,000 for 200 square feet, going by 2026 market estimates, and that's the market's range rather than our price. Your written estimate gives you the figure for the room we plan together.
Do I need a coastal permit for a sunroom in Manhattan Beach?
You do if your property is in the city's Coastal Zone and the project isn't exempt or excluded. You can check your address on the city's Coastal Zone map before we meet, and having that result ready makes the permit conversation easier. We confirm what your job needs with the city either way.
How much can a contractor ask for up front on a sunroom in California?
On a job the size of a sunroom, state rules cap the down payment at $1,000. Every other payment has to be written into the contract and tied to work completed or materials delivered, so you pay as the room comes together.
Can my old patio slab hold a sunroom?
It can if it's in like-new condition, because one sunroom maker's installation guide prefers a new slab or deck and only allows an existing one in that shape. I'll look closely at yours on the first visit and tell you then if a new base needs to be part of the plan.
How do I keep a sunroom from getting too hot?
Plan shading, ventilation and insulation into the room from the start, because research on sunspaces finds that even rooms in mild climates need all three to stay comfortable. When you compare designs, ask how each one handles shade, airflow and insulation, since those choices decide how the room feels on a warm afternoon.
How do I take care of a sunroom once it's built?
Have the roof and gutters looked at once a year, which is what one sunroom company's owner guide suggests. They're what keep water off the room and away from it, so a yearly look is an easy habit worth keeping.
