MULTI-GENERATIONAL LIVING & RENTAL VALUE. DESIGNED FOR AUTONOMY.
California ADU legislation offers homeowners unprecedented opportunities to build secondary living residences. We design and build detached guest houses, attached rental apartments, garage conversions, and pool cabanas that look and feel like bespoke luxury villas.
Unlike prefab kit boxes, Radessen builds custom site-built ADUs that honor your property's topography, trees, privacy lines, and existing residential aesthetic.
We custom-design every ADU to maximize natural daylight, preserve yard privacy, and complement the main house's exterior styling and rooflines.
Capitalizing on California state laws that exempt many ADUs from local setback restrictions, impact fees, and parking mandates to expedite city approval.
Dedicated sub-panels, separate gas or high-efficiency all-electric heat pump systems, tankless water heaters, and independent sewer connections.
Vaulted ceilings with exposed beams, full-sized kitchens with built-in appliances, stacked laundry closets, and spa-inspired bathrooms.
Building a premium asset that commands top market rents or provides comfortable, private living for aging parents and adult children.
Grading, trenching, retaining walls, and retaining drainage management on Bay Area hillside lots without disrupting existing landscaping.
From initial zoning feasibility through foundation, framing, finishes, and final utility sign-offs, we handle everything under one roof.
