Composite Decks
Low-maintenance Trex and TimberTech composite decking that resists fading, staining, and mold. 25-year manufacturer warranty with no annual sealing required.
Hardwood Decks
Ipe, redwood, and cedar decks with natural beauty and durability. Ideal for Bay Area homes where the deck is the centerpiece of outdoor living.
Multi-Level Decks
Tiered deck designs for hillside and sloped lots — common across the East Bay hills, Marin, and Peninsula. Engineered for Bay Area soil and seismic conditions.
Deck Remodels & Repairs
Replace rotting boards, upgrade railings, add built-in seating, and bring aging decks up to current code. Most deck remodels complete in 2 to 4 weeks.
San Rafael's Mediterranean microclimate is one of the warmest and sunniest in Marin County. The city averages 260+ sunny days per year with summer highs reaching 85 to 95 degrees. This climate supports year-round outdoor living and makes deck investment particularly rewarding. Many San Rafael homeowners incorporate shade structures and outdoor kitchens into their deck designs.
San Rafael building permits for decks are issued through the Community Development Department. Decks over 30 inches above grade require permits with structural plans. Hillside properties may need geotechnical review. Properties in WUI zones require fire-rated materials. Permit timelines average 2 to 4 weeks. Hamilton Exteriors handles all applications and inspections.
Deck costs in San Rafael range from $18,000 to $60,000 depending on size, material, and site complexity. Composite decking runs $35 to $55 per square foot installed. Redwood costs $30 to $50 per square foot. Ipe hardwood ranges from $50 to $75 per square foot. Hillside builds with engineered foundations run $35,000 to $60,000. We provide free, itemized estimates.
Neighborhoods We Serve
Deck Building Across San Rafael Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.
Peacock Gap
Peacock Gap hillside homes overlooking the San Rafael canal and Bay enjoy warm sun exposure and protected hillside settings. Multi-level decks take advantage of the natural grade to create tiered outdoor rooms with water and mountain views.
Dominican
Dominican neighborhood homes near the university campus feature mature landscaping and moderate hillside lots. Decks here complement mid-century and ranch architecture with warm composite or redwood materials, creating sheltered outdoor dining areas.
Terra Linda
Terra Linda Eichler homes and ranch properties have classic indoor-outdoor design that decks enhance naturally. Ground-level and slightly raised decks connect the atriums and glass walls to backyard entertaining spaces in this warm Marin microclimate.
Lucas Valley
Lucas Valley properties on larger lots provide space for expansive deck installations. The valley warmth and surrounding hills create a protected outdoor environment where decks serve as year-round living spaces for dining and relaxation.
San Rafael Hills
San Rafael Hills homes on steeper terrain benefit from elevated decks with panoramic views of Mt Tamalpais and the Marin hills. Engineered post systems anchor into the hillside to create stable, level outdoor platforms above the slope.
Sun Valley
Sun Valley lives up to its name with generous sun exposure that supports year-round deck use. Ground-level composite decks with shade structures like pergolas are popular here, balancing sun enjoyment with protection during warm summer afternoons.
Marinwood
Marinwood families invest in backyard deck spaces that extend the home into generous outdoor areas. Low-maintenance composite decking is the popular choice for households with children, offering splinter-free surfaces and easy cleaning.
Glenwood
Glenwood properties on hillside lots above downtown San Rafael enjoy elevated positions with views. Decks here create outdoor entertaining space that takes advantage of the altitude and the warm Mediterranean microclimate.

Do I need a permit for my exterior project?
Permit requirements depend on the project scope and local jurisdiction. Hamilton Exteriors coordinates required applications, plan documents, corrections, and inspections. Permit fees and allowances appear in the proposal before construction begins.
Do I need a permit for a deck in San Rafael?
Yes, if your deck is more than 30 inches above grade, attached to a structure, or over 200 square feet. The City of San Rafael Building Division requires a permit and final inspection. We handle the entire permit process for you. Permit fees range from $300 to $1,200 (Hamilton Exteriors 2024-2026 project data).
How much does a deck cost in San Rafael?
A typical composite deck in San Rafael costs $18,000 to $35,000 for 300 square feet (Hamilton Exteriors 2024-2026 project data). Ipe hardwood decks run $30,000 to $55,000 for 500 square feet. Redwood decks start around $15,000 for 300 square feet. Costs include materials, labor, footings, framing, railing, and permit fees.
