Rohnert Park Concrete is a concrete contractor serving San Rafael, CA, specializing in decorative concrete, driveway replacement, and concrete patios for Marin County homeowners. We have completed concrete projects on hillside lots, flat Canal-area properties, and the mid-century ranch homes of Terra Linda, and we respond to every new inquiry within one business day.

San Rafael's mix of hillside lots, mid-century ranch homes, and dense Canal-area properties creates a wide range of concrete needs. Here is what we bring to each of them.
Marin County homeowners invest heavily in their properties, and plain gray concrete rarely matches that standard. Stamped and stained decorative concrete gives driveways, patios, and walkways the finished look that San Rafael's higher-value homes call for, at a cost well below natural stone.

Many of San Rafael's Terra Linda and Sun Valley ranch homes still have their original 1950s and 1960s driveways. After 60-plus years of Marin County's wet winters and clay soil movement, those surfaces are usually past the point of patching. A new concrete driveway, properly bedded on compacted gravel, handles the seasonal soil expansion far better than the original pour did.
Hillside properties above downtown San Rafael and off Mission Avenue deal with soil movement and erosion every rainy season. A reinforced concrete retaining wall keeps that pressure contained and protects the flat areas around the home. On steep San Rafael lots, a well-built wall also creates usable flat space that a sloped yard cannot provide.
San Rafael's mild climate makes outdoor living a practical part of the home, not just a summer amenity. A concrete patio extends the livable footprint of the house and handles the damp winter conditions far better than wood decking does. Properly finished concrete also holds up to the morning fog and brief afternoon sun that characterize Marin County's coastal weather patterns.
Hillside and split-level homes throughout San Rafael rely on exterior steps to connect different yard elevations. Older concrete steps on these properties crack and shift as the ground moves, creating tripping hazards that get worse each wet season. New concrete steps, poured with reinforcement and properly tied into the surrounding grade, stay stable even as the soil beneath them continues to move.
San Rafael's walkable neighborhoods — including the streets just off Fourth Street and the residential blocks of the Canal — see a lot of foot traffic, and cracked or heaved sidewalk panels are a liability issue as much as an aesthetic one. Tree roots in the older parts of town are a frequent culprit, and replacement panels need to account for root management to avoid repeating the same damage.
Marin County's clay-heavy soils are the single biggest factor in how concrete holds up in San Rafael. The clay expands as it absorbs winter rainfall and then contracts during the dry summer months. That seasonal movement puts stress on every concrete slab in the city, and it is why you see so many cracked driveways and heaved walkways in neighborhoods that were built as recently as the 1970s and 1980s. Proper subbase preparation, with compacted gravel beneath the pour, is the only reliable way to isolate a slab from that movement.
San Rafael's hillside neighborhoods add terrain considerations that flat-lot work does not require. Properties above downtown, near Dominican University of California, and along the upper streets off Mission Avenue typically have limited truck access, drainage that runs toward the house rather than away from it, and older foundations that predate California's current building codes. A contractor who has not worked on these lots before will encounter surprises. We have not.
The city's building stock also spans a wide range. Terra Linda's 1950s and 1960s ranch homes, the dense multi-family buildings near the Canal, and the older Craftsman properties above Fourth Street each present different access conditions, property configurations, and permit requirements. The City of San Rafael Community Development Department requires permits for most concrete work, and the review process for hillside projects can involve additional environmental and grading assessments. We handle permit applications as part of every job.
Our crew pulls permits through the City of San Rafael Community Development Department on a regular basis, and we know which project types trigger grading review and which move through standard building permit processing. That distinction matters for scheduling, because grading permits in hillside zones can add two to four weeks to the front end of a project. We factor that in at the estimate stage, not after you have already committed to a start date.
San Rafael sits at the heart of Marin County, bordered by Highway 101 to the east and the Marin County Open Space to the north and west. Most of our work in the city routes through the Central San Rafael and Terra Linda corridors, and we are familiar with the delivery and staging constraints that come with the narrower residential streets in the older neighborhoods near the Marin County Civic Center and downtown. Ready-mix trucks need a clear path and a place to park, and that takes planning on tight urban lots.
We also serve the nearby areas of Napa, CA and Novato, CA, which gives us consistent experience working across Marin and Napa counties and a good working knowledge of the permit offices and soil conditions across this part of the North Bay.
Here is how every project runs from first call to finished surface.
Step 1
Reach us by phone or through the contact form and describe your project. We respond within one business day and will ask a few questions to assess whether a site visit is needed before providing a number.
Step 2
We visit your property, assess the subbase conditions, check truck access, and measure the work area. You receive a written, itemized estimate that covers materials, labor, demolition if needed, and permit fees — no surprises later.
Step 3
We pull the permit, prepare the subbase with compacted gravel, set the forms, and place reinforcement. The concrete is poured and finished in a single day for most residential projects. You do not need to be present for the pour, but the work area needs to stay clear.
Step 4
The surface needs 24 to 48 hours before foot traffic and about a week before vehicles. We schedule the city inspection, clear the site, and walk you through any care or resealing instructions before we leave.
We serve all of San Rafael — from Terra Linda and the Canal to the hillside neighborhoods above downtown. Written estimates, no pressure.

San Rafael is Marin County's oldest and largest city, incorporated in 1874 and home to roughly 61,000 residents. It serves as the county seat and is one of the most recognizable addresses in the North Bay, anchored by the landmark Marin County Civic Center, designed by Frank Lloyd Wright. The city's walkable downtown along Fourth Street, the hilltop campus of Dominican University of California, and the dense Canal neighborhood near the bay give San Rafael a wider range of property types than most cities of its size.
The housing stock spans more than a century of construction styles. The Terra Linda and Sun Valley neighborhoods contain mostly single-story ranch homes built in the 1950s and 1960s, many of which still have their original concrete driveways and flatwork. The hillside streets above downtown hold older Craftsman bungalows and Spanish-style stucco homes on steep, wooded lots. The Canal area has a dense concentration of older multi-family buildings, many dating to the 1960s and 1970s. Across all three types, the common thread is a housing stock old enough to need significant concrete maintenance and replacement work.
San Rafael sits between the rest of Marin County to the south and north and shares a regional character with nearby Novato, CA. Both cities have a large share of pre-1980 homes on clay soils, which means concrete cracking and heaving are everyday maintenance realities for homeowners in this part of the county.
