About Chino Hills, CA

Chino Hills is mostly neighborhoods built into the hills, and you see it in the backyards. A lot of them have a concrete patio off the family room with the yard rising or dropping just past the edge, or a raised deck built out over a slope because there wasn't room for a flat yard. With open hillside and Chino Hills State Park at the end of so many streets, people want a room where they can enjoy that view without the sun, the wind and the bugs. Most of the calls we get are from homeowners who already have the patio or deck and want a lot more use out of it.

It's a different job than the flatter lots down in Chino, and the ground decides a lot of it. Before I sketch a room here, I want to know where the water goes in a hard rain and what's holding up that deck, because a room only sits as well as what's under it.

Services in Chino Hills, CA

  • Patio-to-sunroom conversion

    Plenty of Chino Hills homes already have a concrete slab off the family room, often with the yard climbing away right behind it. We check that slab for cracks and level before we turn it into a closed room, and we fix what we find first, because a room is only as square as the floor it sits on.

  • Deck-to-sunroom conversion

    Where the lot drops off, the outdoor space is usually a raised deck, and most of those were built to hold chairs, not walls and a roof. We look underneath at the posts, footings and framing and tell you plainly whether it can carry a room or needs new support first.

  • Enclosed patio rooms

    If your covered patio collects dust and leaves blowing in off the hills, enclosed patio rooms close it in with walls and windows so it stays clean and usable. We build from the cover you have where it's sound and replace the parts that aren't.

  • Patio cover installation

    A lot of yards here came with a lattice or wood cover that gives a little shade and not much else. We put up a solid patio cover that sends rainwater where your lot can take it, and we can set it up so it's ready to close in later.

  • Screen room installation

    Homes that back up to open hillside get the views, and they get the bugs too. A screen room lets you sit out in the evening with the air moving through, without paying for full glass walls.

  • Four season sunrooms

    When you want a room you'll use every month of the year, a four season sunroom with an insulated roof, walls and glass is the way to go. We pick the glass with you based on which way the room faces, because a room catching the afternoon sun needs different glass than one looking at the hills.

What a sunroom job in Chino Hills turns on

In Chino Hills, building permits come from the city's Building and Safety Division, and since a sunroom or enclosed patio adds to or changes your house, most of these jobs need one before our installers can start. That's the part of the schedule nobody can rush, so I reach out to the city early and we handle the paperwork, which means you know what to expect before anything gets ordered. Two things are worth checking on any contractor you talk to. The state requires a license from the California Contractors State License Board for anyone who builds or alters a structure when the job needs a building permit, uses employees, or runs $1,000 or more in labor and materials, which covers just about any sunroom, and a contractor coming in from outside the city also needs a Chino Hills business license. We're licensed and fully insured, and happy to show you.

We're based in Jurupa Valley and work in many of the cities around it, and Chino Hills jobs tend to turn on the same few things. The price moves with the size of the room, glass or screen, how well it's insulated, how the new roof ties into yours, and how much work the slab, deck or cover needs before we build on it. The schedule moves mostly with the permit and with any repair or ground work that has to happen first. Your written estimate lays those options out side by side, so you can see what each choice changes.

Chino Hills, CA properties and local conditions

The city itself says that with these hills and the way the streets and storm drains are laid out, heavy rain here can cause roadway flooding and landslides, and sometimes a road can't be driven at all. For a sunroom, that means the water coming off a slope or a new roof needs a planned place to go. We look at how your yard drains before we place the room, run the gutters and downspouts away from the slab and the hillside, and plan our deliveries around the weather so a storm doesn't leave materials stuck at the bottom of the hill.

Many homes here have a patio cover a builder or an earlier owner put up years ago, and most were never meant to hold walls or glass. We check how it's fastened to the house and what the posts stand on, and if it can't carry a room, we tell you and build a real roof instead.

Frequently asked questions

Which small backyard projects in Chino Hills don't need a building permit?

The city's list of work exempt from permits covers a one-story detached shed up to 10 feet tall and 120 square feet, a deck up to 200 square feet and 30 inches off the ground that stands apart from the house and serves no required exit door, and finish work like painting, tile and cabinets. A sunroom or enclosed patio attached to your house isn't on that list, so plan on a permit, and we take care of that paperwork for you.

How do I know if a roof job in Chino Hills needs a permit?

City policy lets you patch or replace a specific damaged area of roof covering, tile or underlayment without a building permit, but redoing a whole roof plane counts as a partial re-roof and needs one. Replacing any section of sheathing, the plywood under your tile or shingles, also needs a re-roof permit, which can come up when a sunroom ties into your house roof. If your job falls somewhere between a patch and a full plane, the city's Building and Safety Division answers permit questions.

Does a sunroom roof in Chino Hills need a Class A fire rating?

Yes, the city's building code requires Class A roof coverings, the highest fire rating, though an addition that replaces no more than 25 percent of your total roof area in a 12-month period may match your existing roof. That matters here because the city's updated maps put over 24,000 acres of Chino Hills in a wildfire threat zone. We go over roof materials with you at the estimate so the room fits the rule and your house.

How do I apply for a building permit for a sunroom in Chino Hills?

Building permit applications in Chino Hills go online through the city's Virtual Development Services Portal, and the permit has to be issued before work on the room starts. We file that application and handle the paperwork for you, and we contact the city early so you know what to expect.

Do I need a permit for a retaining wall next to a new sunroom in Chino Hills?

Usually yes, because a wall beside a sunroom carries the load of the room, and the city only exempts walls with no surcharge from an adjacent structure. The exemption covers masonry or concrete walls up to 4 feet tall, or retaining walls holding back less than 3 feet of soil, and only when the soil behind slopes less than 4 to 1, the wall holds back no flammable or combustible liquids, and every part sits more than 5 feet from any property line. If your room needs a wall, we work out the permit along with the rest of the job.

What drives the cost of a sunroom on a hillside lot in Chino Hills?

A hillside lot usually costs more when the room needs footings dug into a slope, extra support under a raised deck, or new drainage to carry water away from the room. Grading or excavation also needs a permit from the city's building official first, apart from a few listed exemptions, and it's only issued once the project has its zoning approvals, so ground work can add time as well as cost. I look at all of that on the first visit so it's in your estimate, not a surprise later.
