Serving Brea, CA and surrounding areas. (657) 478-7348
Elite Brea Sunrooms & Patios is Rowland Heights' local sunroom contractor, building enclosed patio rooms, all-season sunrooms, and custom additions for the single-family homes throughout this unincorporated San Gabriel Valley community. We have served the eastern Los Angeles County area since 2020 and handle every permit through LA County's Building and Safety Division, from plan preparation through final inspection.
Many Rowland Heights homes from the 1970s and 1980s were built with concrete slab patios that now sit exposed to the sun, Santa Ana winds, and the wet winters that can push water against the back of the house. Enclosing that existing space is often the most cost-effective way to add a usable room - provided the slab is still level and structurally sound. We assess every slab before designing around it, because a 50-year-old concrete pad in the San Gabriel Valley clay has often moved. See the full details of our enclosed patio rooms service.
Rowland Heights summers are hot and dry, with temperatures regularly reaching the mid-90s and no marine layer to bring relief in the evenings. An all-season room with insulated walls, Low-E glass, and a dedicated mini-split gives you a fully comfortable space through the hot months and into the mild winters. For homeowners who want the new room to feel like a real part of the house - not a sunporch they avoid from June through September - this is the right option.
Homes in Rowland Heights vary more than they appear to from the street. Lots near the Puente Hills have slopes and grade changes that a standard catalog design cannot accommodate. Some properties have specific roof angles, view corridors, or setback conditions that require a custom approach. We design each room around the actual conditions at your property - lot grade, existing roofline, and exterior materials - so the finished room looks like it was always there.
Most Rowland Heights homes were built for the family sizes and lifestyles of the 1970s and 1980s, and many owners today need more living space without moving. A permitted sunroom addition adds square footage that counts toward appraised value, creates a room with a genuine connection to the yard, and works with the existing structure rather than fighting it. Because Rowland Heights is unincorporated, permits run through LA County - we know that process and handle it for you.
Before committing to a full enclosure, some Rowland Heights homeowners want a patio cover - solid shade overhead, protection from the winter rains, and a better outdoor experience for most of the year. A well-built aluminum or wood patio cover changes how you use the backyard and can serve as the first step toward a full enclosure later. We size and pitch every cover to handle the volume of rain that eastern LA County receives during El Nino wet seasons.
Fall and spring evenings in Rowland Heights - after the summer heat breaks but before the rainy season - are genuinely pleasant outdoor weather. A screen room extends that usable season and keeps out the insects and the fine dust that Santa Ana winds push across the area each November. This is a lower-cost option than a fully enclosed room and is well suited to the standard suburban lots that make up most of the residential neighborhoods in this community.
Rowland Heights sits at the base of the Puente Hills in the eastern San Gabriel Valley, and that location shapes almost every aspect of how sunroom and patio enclosure work gets done here. The community was built primarily between the 1960s and the 1990s, which means most homes are in the 30- to 60-year age range where major improvements - not just maintenance - are the right move. The housing stock is almost entirely single-family, owner-occupied, and the homeownership rates here are high by Los Angeles County standards. These are people who plan to stay and who care about getting work done properly. The combination of an aging housing stock, high home values, and owners who take the long view is what makes Rowland Heights a community where sunroom additions are in steady demand.
The local conditions that affect the work here are specific. The expansive clay soils common throughout the eastern San Gabriel Valley swell with winter rains and shrink in the dry summer months - seasonal movement that cracks concrete flatwork, stresses foundations, and can shift the framing connections in a sunroom that was not designed to account for it. Properties closer to the Puente Hills add sloped lot conditions on top of the soil challenges: grade changes that require stepped foundations, drainage corrections, and sometimes retaining wall assessments before framing can begin. Santa Ana wind events, which roll through Rowland Heights each fall with gusts that can exceed 50 miles per hour, put stress on roof connections and exterior seals that need to be built to a higher standard than the product minimums suggest. These conditions are not rare edge cases - they are the normal operating environment for every sunroom we build in this community.
Our crew works throughout Rowland Heights regularly, and because the community is unincorporated, we pull permits through the LA County Department of Public Works Building and Safety Division for every project we do here. Working in an unincorporated community means permit submittals go to the county rather than a city building department, and the review process has its own documentation requirements that differ from neighboring incorporated cities like Walnut and Diamond Bar. We know the process and prepare submittals accordingly, which keeps plan review moving without back-and-forth over missing information.
Rowland Heights is a community most outsiders underestimate. Colima Road and Nogales Street form the commercial core, and the stretch around the 99 Ranch Market on Colima is one of the most active commercial corridors in the eastern San Gabriel Valley. Fullerton Road connects the community to the freeway system, and Nogales Street climbs north toward the Puente Hills Preserve, where many of the area's hillside properties are located. The residential neighborhoods fan out from this core in all directions - flat streets near the commercial areas, steeper terrain as you move toward the hills, and the Rowland Heights Community Center anchoring the neighborhood's civic identity.
We also serve the surrounding communities throughout this part of the county. If you are in Walnut just to the east, or in Diamond Bar a few miles further, we cover those areas as well.
Reach us by phone at (657) 478-7348 or through the contact form on this site. We reply within one business day. You do not need any plans or drawings - just a general idea of what you want to build and where on your property it would go.
We visit your home to look at the space, check the existing slab or foundation, assess lot grade and drainage, and identify any soil or structural conditions that need to be addressed. The visit is free and typically takes 30 to 60 minutes. For properties near the Puente Hills, this is also where we flag any slope-related work that would affect the design or cost - information that is far better to have upfront than to discover once work has started.
After you approve the estimate, we prepare and submit the permit application to LA County Building and Safety. Plan review typically takes two to four weeks. Construction begins after permit approval and runs two to five weeks depending on project scope. We coordinate access with you as the work progresses and keep the site clean and secure each evening.
When construction is complete, LA County sends an inspector for the final review. We walk through the room with you first to make sure everything meets the design and your expectations. After the county issues final approval, we give you copies of the permit documentation - records your lender, insurer, and future buyer will want to see.

(657) 478-7348Rowland Heights is an unincorporated community in Los Angeles County with a population of roughly 48,000 to 50,000 people. It sits in the eastern San Gabriel Valley, bordered by Walnut to the east, Diamond Bar to the southeast, and the City of Industry to the west. The community was developed primarily between the 1960s and 1990s, and the housing stock reflects that era - mostly single-family homes with stucco exteriors, concrete driveways, and backyards that face the Puente Hills to the north. Homeownership rates are high compared to most of Los Angeles County, and home values typically range from the mid-$700,000s into the $800,000s - a level that makes quality home improvements a financially sensible investment for most owners. The community is well known for its diverse character, with a significant Asian-American population and a commercial corridor along Colima Road that draws visitors from across the San Gabriel Valley.
The residential areas spread out from the Colima and Nogales Street corridor in all directions. Streets in the lower, flatter parts of the community near Colima Road are typical of San Gabriel Valley suburban development - uniform lot sizes, attached two-car garages, and concrete slab patios in the back. As you move north toward the Puente Hills Preserve, the terrain rises, lots become less uniform, and sloped driveways and retaining walls become more common. The community's civic center is anchored by the Rowland Heights Community Center off Nogales Street. We serve Rowland Heights and the surrounding communities, including Walnut to the east and Diamond Bar to the southeast.
