How Do ADUs Work in Santa Clarita, CA?
Thinking about building or buying a property with an Accessory Dwelling Unit (ADU)? Here’s how it works in Santa Clarita, Valencia, Saugus, Newhall, Stevenson Ranch, Canyon Country and Castaic.
What’s an ADU?
An Accessory Dwelling Unit is a separate living space on a residential property. It can be attached (like a converted garage), detached (a small unit in the backyard), or even a junior ADU (within the existing home).
Local Regulations and Process
- ADUs are legal under California state law and supported by the City of Santa Clarita
- Must follow setback, height, and size requirements (generally under 1,200 sq ft)
- You’ll need permits, inspections, and site plans approved by the city
Popular Uses for ADUs
- Housing for extended family
- Rental income from long-term tenants
- Home offices or guest suites
Costs and Financing
Expect to spend $100K–$300K+ depending on the type and finishes. Some lenders now offer renovation loans that include ADU construction.
