They finished the four-season room in right on schedule and handled all the permit paperwork themselves. The room stays cool even on 100-degree days, which was the whole point. We use it every single morning now.
David R., Redlands - Four season sunrooms
Our patio was basically a dead zone in the summer. They enclosed it with a proper screen room and now we eat dinner out there almost every night. The whole project was cleaner and faster than I expected.
Maria T., Fontana - Screen room installation
I was nervous about the HOA approval process but they handled all of it. They provided the drawings, answered the committee's questions, and got approval before breaking ground. No surprises from start to finish.

Yes - any permanent room addition in California requires a permit before work begins. Skipping it can cause serious problems when you sell your home. The California Department of Housing and Community Development provides statewide standards that local departments enforce.
Only if it is built wrong. The right window glazing reflects heat while letting in light, and a connection to your existing HVAC keeps the room comfortable even in triple digits. Glazing choice is the single most important decision for Inland Empire homerooms.
San Bernardino winters rarely drop below the mid-40s, so three-season rooms are usable for most of the year. Four-season rooms cost more but give you year-round comfort regardless of weather. Most homeowners here find the value difference is smaller than the price difference.
Santa Ana events can exceed 60 mph in the Inland Empire. A properly anchored and framed sunroom handles those gusts without issue. A poorly attached one will rattle, leak, or worse. Always ask a contractor specifically how the room is anchored to your home's existing structure.
A fully enclosed sunroom with sealed, high-performance windows lets you enjoy natural light and the view on days when outdoor air quality is poor. According to the South Coast Air Quality Management District, the Inland Empire regularly experiences elevated PM2.5 levels during fire season.
San Bernardino's soils expand when wet and shrink in dry heat - a cycle that can crack foundations not designed for it. A reputable contractor assesses soil conditions before designing your foundation. The California Geological Survey documents expansive soil zones throughout the Inland Empire.

San Bernardino Sunrooms & Patios is a licensed and insured sunroom contractor company based in San Bernardino, CA, serving 12 cities across the Inland Empire since 2015. We are licensed by the California Contractors State License Board, which governs all residential and commercial contracting work in the state. In over a decade of operation, we have completed sunroom additions, patio enclosures, and room conversions across San Bernardino County. Learn more about our background and approach on our About page.
Existing slabs and patio covers can often be incorporated into the new sunroom design, reducing foundation costs. A site visit confirms what is usable and what needs to be replaced.
Many HOAs allow sunrooms but restrict colors, materials, or roof styles. Knowing the rules before design begins prevents expensive plan revisions. We help you navigate the approval process.
San Bernardino's permit review can take a few weeks. Building before permit approval risks fines and required teardown. Build that lead time into your project plan from the start.

San Bernardino is a city of about 222,000 people sitting at the base of the San Bernardino National Forest, with neighborhoods ranging from older postwar streets near downtown to newer developments on the north and east sides. The city serves as the county seat of San Bernardino County, the largest county by area in the contiguous United States. A large share of the housing stock was built between the 1940s and 1980s, meaning many homes have aging systems that need attention alongside any new construction.
Local landmarks and institutions shape what homeowners experience here. Students and staff at California State University, San Bernardino live in the neighborhoods on the north side of the city. Historic Route 66 runs through San Bernardino, and some of the homes along those older corridors have been in families for generations. Foothills neighborhoods closer to the mountains tend to have larger lots and older custom-built homes that require a different approach than the standard postwar ranch homes found elsewhere in the city.
The climate here is what drives most of the decisions we make when building a sunroom. Summers regularly push past 100 degrees, Santa Ana winds hit every fall, and wildfire smoke can make outdoor living unpleasant for weeks at a time. A sunroom built for San Bernardino is not the same as one built for a milder coastal city - and San Bernardino Sunrooms & Patios has been building for this specific climate since 2015.
