The city's strong emphasis on architectural harmony and neighborhood aesthetics means that building an Accessory Dwelling Unit (ADU) in San Marino requires careful planning, experienced professionals, and a deep understanding of local regulations.
San Marino follows California state ADU law, which mandates that cities allow ADUs on single-family residential lots.

The city's Planning and Building Department has specific review processes, and permit approvals can be more detailed compared to neighboring cities.

This reduces costly delays and ensures your project moves forward efficiently.
Given the large lot sizes typical of San Marino properties, homeowners have several ADU options available to them:
Adding an ADU to your San Marino property is a smart investment. With median home values among the highest in Southern California, a well-designed ADU can significantly increase property value and generate rental income. Professional ADU contractors in San Marino understand how to deliver high-quality construction that meets the city's elevated standards while maximizing your return on investment.
