Accessory Dwelling Unit Planning in San Marino
For homeowners in San Marino, a well planned ADU can turn an underused garage, side yard, or backyard area into real living space without forcing the main home to work harder than it should. The area includes prestige homes, large parcels, and traditional architecture, which means successful projects need more than a copied floor plan. ADU planning should consider privacy, parking, utility routing, outdoor space, and the lifestyle goals of owners seeking discreet additional living space.
