Building an Accessory Dwelling Unit here requires a contractor who understands not just state ADU law, but also the specific aesthetic and regulatory expectations of this tight-knit 3.4-square-mile city.
Like all California cities, South Pasadena must comply with California state ADU law (AB 68, AB 881, SB 13), which has significantly streamlined the permitting process statewide. However, the city still enforces its own local standards within the framework allowed by state law. Key regulations that experienced ADU contractors in South Pasadena must navigate include:
