You want a sunroom that looks like it was always part of your house. We design every custom sunroom around your home, your lot, and Pomona's climate.
You want a sunroom that looks like it was always part of your house. We design every custom sunroom around your home, your lot, and Pomona's climate.
Custom sunrooms in Pomona are designed from scratch around your home and lot - no pre-packaged kits, no one-size-fits-all layouts - and most projects take eight to fourteen weeks from first conversation to final inspection.
A custom sunroom is different from a pre-built kit because the framing, roofline, and glass are all engineered to match your specific home. For Pomona homeowners, that means accounting for intense summer heat, California's seismic requirements, and - in many neighborhoods - HOA approval before the permit is even submitted. If you are still deciding between a custom build and a more standardized option, our sunroom construction page walks through the full construction process in detail.
The goal is a room that looks like it was always there - not an addition bolted onto the side of your house. That takes more planning upfront, but the finished result holds its value and works the way you actually want it to work.
In Pomona, outdoor spaces become genuinely uncomfortable from June through September. If you find yourself retreating inside every afternoon, a sunroom with heat-reducing glass gives you that outdoor connection without the heat. You end up with a space you can use twelve months a year.
Many Pomona homes from the mid-20th century were built with modest square footage, and families grow. A custom sunroom adds a real, usable room - home office, playroom, reading nook - without the disruption and cost of a full addition. The key is that it is designed to look intentional, not tacked on.
A covered patio is not a room. If the space you have leaks, lets in bugs, or gets too cold in winter, you are already spending time out there wishing it were more. A custom sunroom turns that transitional space into a real room with real weather protection.
Pomona's sunny climate means a well-designed sunroom can be filled with natural light for most of the day, which makes it a genuinely good place to work. A dedicated room with a door also gives you the mental separation between work and home that a corner of the living room cannot provide.
Every custom sunroom project starts with a site visit, measurements, and a conversation about what you actually want the room to do. From there, we handle the design, permit submission, foundation work, framing, glass installation, and finishing - so you are not managing a dozen separate contractors. For homeowners who want a room that connects to their home's heating and cooling system, we also build full sunroom construction projects with climate control built in from day one.
If you are still in the planning phase and want to get the design right before committing to a build, our sunroom design service works through layouts, glass options, and structural considerations so you have a clear plan before any permits are submitted. The design phase is also the right time to work through HOA requirements if your neighborhood has them.
Best for homeowners who want a sunroom that integrates seamlessly with their home's existing roofline, materials, and style - handled from permit to final walkthrough.
Best for Pomona homeowners who want the room comfortable year-round, with heating and cooling connected to the home's existing system or a dedicated mini-split.
Best for homeowners in the planning phase who want a clear design and permit-ready drawings before committing to a full build contract.
Best for homeowners in Pomona neighborhoods with active HOAs, where the exterior design must match specific materials, colors, or roofline requirements before approval.
Pomona summers are genuinely intense - temperatures regularly climb above 95 degrees, and the sun angle in the eastern San Gabriel Valley means afternoon heat can be brutal. A custom sunroom built for this climate uses heat-reflective glass rated specifically for high-sun environments, not the same products used in cooler parts of the country. That distinction is what separates a room you use twelve months a year from one you abandon by May. Pomona's housing stock also skews older - many homes were built in the 1940s through 1960s - which means the wall your sunroom connects to may have older framing or wiring that needs attention before construction can proceed. Custom work handles those surprises more gracefully than a kit installation.
California's seismic requirements add another layer that custom design handles better than pre-packaged systems. Any addition to a Pomona home must be anchored to the existing structure in a way that meets earthquake safety standards, and that connection point is designed room by room - not cut from a template. Homeowners in San Dimas and La Verne face the same climate and code conditions as Pomona, and we bring the same level of design attention to projects throughout the area.
We ask what you want the room to do, roughly where on your home you are thinking, and whether you have a budget range. We reply within one business day and will not push you to commit to anything on the first call.
We come to your home, take measurements, and check the wall or corner where the sunroom will attach. This visit takes one to two hours and is your best chance to ask questions. After the visit, you receive a written estimate that breaks down every major cost.
We handle the permit application to Pomona's Building and Safety Division. Approval typically takes two to six weeks. If your neighborhood has an HOA, we submit both requests in parallel so the two approval processes run at the same time, not back to back.
Once permits are approved, construction begins - foundation, framing, glass, and finishing. A city inspector reviews the work before we close out the project. We walk you through the finished room, answer any questions, and provide warranty documentation before we leave.
No obligation. We come to your home, measure the space, and give you a detailed written estimate. Permit questions included at no charge.
Every custom sunroom we build in Pomona uses glass rated for high solar heat gain - the same kind of performance difference that separates a comfortable August afternoon from an unusable oven. We do not use the same glass spec in Pomona that works in San Francisco; the climates are not the same.
Any contractor who asks you to pull your own permit is a red flag. We handle every permit application through the City of Pomona's Building and Safety Division in our name - which means we are legally accountable for the work, and you have city inspector sign-off on your records. Verify any contractor's license on the CSLB website before signing anything.
Pomona is in an active earthquake zone, and every sunroom we build is anchored to your home's existing structure to meet California's seismic safety requirements. This is not just a code checkbox - it is what keeps the room attached to your house if the ground moves.
We give you a detailed written estimate that breaks down every major cost, and we flag potential variables - like what might be found inside an older Pomona home's walls - before you sign a contract. The price you agree to is the price you pay, barring anything genuinely unexpected.
These are not marketing claims - they are the things that come up in every project and that we have had to solve for real Pomona homeowners. We stay accountable from the first site visit to the final city inspection.
