Is Building an ADU Worth It in Santa Clarita?
Accessory Dwelling Units (ADUs) — also known as guest houses, in-law suites, or backyard homes — are becoming increasingly popular throughout Santa Clarita. But is building an ADU really worth it? In this guide, we’ll break down the costs, benefits, legal requirements, and the return on investment (ROI) to help you decide if an ADU makes sense for your property.
What is an ADU?
An ADU is a secondary, self-contained living space on your property. It can be:
-
Detached (a small house in the backyard)
-
Attached (connected to your main home)
-
Garage conversion (turning an existing garage into a living unit)
Thanks to California’s relaxed ADU laws in recent years, building one has become faster and more streamlined than ever before.
How Much Does It Cost to Build an ADU in Santa Clarita?
The cost of an ADU in Santa Clarita typically ranges between $100,000–$300,000, depending on:
-
Size and layout
-
Whether it’s attached or detached
-
Site conditions and utilities
-
Permitting and architectural design
Pro tip: Fauci Construction helps streamline the design–build process, saving time and money while navigating local building codes.
5 Reasons Why Building an ADU Is Worth It
1. Generate Passive Rental Income
Many homeowners are renting out their ADUs for $1,500–$2,500/month, especially in high-demand areas like Valencia and Canyon Country.
2. Increase Property Value
Homes with legal ADUs often appraise 20–30% higher than similar homes without one.
3. Multigenerational Living
ADUs allow family members — like aging parents or adult children — to live nearby while maintaining privacy and independence.
4. Flexible Use
Use it as a home office, gym, studio, or even a short-term rental like Airbnb.
5. Legal Protection Under California Law
California Senate Bills (SB9/SB10 and AB 68) have made it easier than ever to build and permit an ADU, bypassing previous red tape and zoning barriers.
