Premier Santa Rosa Sunrooms & Patios builds solariums, custom sunrooms, patio enclosures, and all season rooms for Fairfax homeowners in Marin County. We have served this area since 2017, regularly work on sloped hillside lots and older wood-frame homes, and handle all Town of Fairfax permitting including fire-safety compliance.
Fairfax sits in a narrow valley with steep wooded hillsides on all sides, which means many homes lose direct sunlight for much of the day during the short winter months. A solarium - with its glass roof and walls - captures available light from above as well as the sides, making it the most effective way to bring natural light into a Marin County home year-round. Our solarium installations use thermally broken aluminum framing and insulated glazing to handle the damp Fairfax winters without condensation or heat loss.
Most Fairfax homes were built between the 1920s and the 1960s, and many are wood-frame construction with original foundations and distinctive proportions that make standard modular sunroom systems a poor fit. A custom sunroom is drawn to match your existing roofline, siding, and window styles so the addition looks like it belongs rather than something that was bolted on later.
Fairfax winters are wet - close to 50 inches of rain falls in a heavy year - and the persistent cool, damp conditions from November through March make an uninsulated three season room uncomfortable for months at a time. An all season room with insulated walls, a thermally broken frame, and a mini-split keeps the space usable through the heart of the Marin rainy season and into the warm, dry summer months.
A number of Fairfax homes - particularly those built in the 1940s through 1960s - have simple covered patios or open decks attached to the rear of the house. Enclosing that existing covered space into a usable room is one of the most cost-effective projects we do in Fairfax, converting what is often a neglected outdoor slab into a year-round room by adding walls and glazing to the existing overhead structure.
During fire season - typically July through October - Fairfax can see smoke and ash from fires burning in the Marin County hills and beyond. A screened enclosure gives homeowners a ventilated outdoor living space that blocks coarse ash and reduces smoke exposure during the weeks when outdoor air quality is at its worst, without sacrificing the airflow that makes outdoor spaces comfortable on mild Marin evenings.
Sloped lots are common in Fairfax, and many homes have raised wood decks built on posts that span the grade change at the rear of the house. Converting a raised deck to an enclosed sunroom - or building a new enclosed room on the existing post foundation - takes advantage of the structural work already in place. On a hillside lot, this is often the most practical path to adding an enclosed room without major excavation.
Fairfax is one of the wettest communities in Marin County - close to 50 inches of rain per year in a heavy winter. Almost every home in town is wood-frame construction, and the combination of persistent cool moisture from November through March and dense tree canopy creates ideal conditions for rot, mold, and moisture intrusion in any sunroom that is not built with the right materials and flashing systems from the start. Aluminum or composite framing, thermally broken glazing, and commercial-grade roof-to-wall flashing are not optional upgrades in Fairfax - they are the baseline for a structure that will still be weathertight in ten years. The clay-heavy soils throughout Marin County also move seasonally, putting stress on any slab or footing that is not properly designed for that expansion-and-contraction cycle.
Wildfire is a genuine risk in Fairfax. The California Office of the State Fire Marshal designates much of the land surrounding Fairfax as a Very High Fire Hazard Severity Zone, which means any new addition must use ember-resistant vents and fire-rated roofing and cladding materials under California Building Code Chapter 7A. Sloped lots - common throughout the hillside streets above town - require foundation designs that account for grade changes, soil instability, and drainage, none of which a contractor unfamiliar with Marin terrain will handle correctly on the first try.
Our crew works throughout Fairfax regularly, and we understand the local conditions that affect sunroom contractor work here. We pull permits with the Town of Fairfax Community Development Department and are familiar with their process for residential additions, including the fire-safety material requirements that apply to properties in or near the Very High Fire Hazard Severity Zone. We regularly work on older wood-frame homes on sloped lots - the type of property that makes up most of the hillside streets above the town center.
Fairfax is a small, tightly knit community centered around the shops and restaurants along Bolinas Road and Broadway in the town center. Sir Francis Drake Boulevard runs through the middle of town and connects Fairfax to San Anselmo and the broader Marin County highway network. Many homes sit on streets that climb steeply up from the valley floor toward the wooded ridge above town, backing up toward Cascade Canyon Open Space Preserve on the eastern side of town.
We serve the neighboring communities as well. To the south, Novato is an active part of our Marin County service area. To the east, Sonoma is part of our regular coverage through the wine country region.
Call or fill out the estimate form and we will respond within one business day. A few basic questions about your home, your lot, and your goals help us prepare for the on-site visit and arrive knowing what to look for.
We visit your Fairfax property to measure, review the slope and foundation conditions, check the existing structure, and talk through your options. The written estimate we provide covers all materials, labor, permit fees, and any site-specific foundation work - so you know the real cost before committing.
We prepare and submit your permit application to the Town of Fairfax on your behalf, including fire-safety material documentation where required. Once the permit is approved - typically two to three weeks for standard residential projects - our crew handles all construction. You do not need to be present every day, but we keep you informed at key milestones.
We schedule and pass the Town of Fairfax final inspection, then walk you through the completed space and cover any questions about operation, seasonal care, and maintenance. The permit is closed, the work is on record with the town, and your new room is ready to use.
We serve Fairfax and Marin County. Call or submit a request and we will respond within one business day - sloped lots and older homes welcome.
(707) 867-4244Fairfax is a small town of about 7,400 people in central Marin County, tucked into a valley surrounded by steep, forested hills. Incorporated in 1931, the town was largely built out between the 1920s and the 1960s - which means most homes in Fairfax are between 55 and 100 years old. The town has very little new construction, and the housing stock is almost entirely wood-frame single-family homes set on lots that range from flat parcels near the town center to steeply sloped hillside properties that back up directly against open space. Median home values are well above $1 million, which reflects the broader Marin County market and a community where owner-occupants make up roughly 60 percent of households - people who plan to stay and take care of their properties.
The town center along Bolinas Road and Broadway has the independent shops and restaurants that give Fairfax its distinct small-town character, and the surrounding hills form the backdrop that most residents see from their back yards. Cascade Canyon Open Space Preserve borders the east side of town, and many residential streets climb directly into the trees. Fairfax sits adjacent to Novato to the north, which is also part of our Marin County service area. For homeowners who are newer to the area, Fairfax is part of Marin County, one of the most densely wooded and topographically varied counties in the Bay Area - a setting that shapes nearly every aspect of how homes here are built and maintained.
