ADU Construction in San Marino – Made Simple with Golden ADU

San Marino homeowners are discovering how Accessory Dwelling Units (ADUs) can transform their properties into versatile living spaces while potentially increasing property values. Golden ADU brings over two decades of design-build expertise to San Marino residents, helping you navigate the entire ADU journey from concept to completion. Whether you’re looking to house family members, create rental income, or build a home office, our locally-based team understands San Marino’s unique architectural character and permitting requirements.

What is an ADU?

An ADU (Accessory Dwelling Unit) is a secondary housing unit on a single-family residential lot. Often called granny flats, in-law suites, or backyard cottages, these versatile spaces provide complete independent living facilities with their own entrance, kitchen, bathroom, and living space. ADUs have become increasingly popular in San Marino as homeowners seek flexible solutions for multigenerational living, rental income, or additional living space.

ADUs come in several forms, including garage conversions (transforming your existing garage into livable space), room additions that expand your current home, detached structures built separately in your yard, or attached units that connect to your main house. Recent California legislation has made the ADU construction process more streamlined, allowing San Marino homeowners to more easily add these valuable spaces to their properties.
