Santa Clarita, CA ADU Construction

Accessory Dwelling Units (ADUs) are known by many names: granny flats, garage conversions, in-law units, backyard garages, secondary units, and more. No matter what you call them, ADUs are an innovative, affordable, effective option for adding much-needed housing. As the space for new construction continues to dwindle, ADUs become increasingly more popular in Southern California. So, whether you want to add a new ADU or you need to bring one into compliance, we are here to help.

The State of California passed laws that make building an ADU fairly simple. Where allowed, homeowners can decide to build either a detached ADU on their property, an attached ADU that is part of a home addition, or an ADU conversion which converts part of your existing property into an ADU (including the conversion of an existing garage into an ADU).

The first step when deciding to build an ADU is to determine what type of ADU best fits your needs, and the physical characteristics of your property. Are you building an ADU as extended family housing or as a rental? We can help you determine the size and type of ADU you need.


  • ADUs are an affordable type of home to construct in California because they do not require paying for land or major new infrastructure.
  • ADUs can provide a source of income for homeowners. An ADU has its own kitchen, living area, and a separate entrance. An ADU may be attached to a house or garage, or it can also be built as a stand-alone unit.
  • ADUs are built with cost-effective wood frame construction. ADUs allow extended families to be near one another while maintaining privacy.
  • ADUs can provide as much living space as many newly-built apartments and condominiums, and they are suited well for couples, small families, friends, young people, and seniors.
  • ADUs give homeowners the flexibility to share independent living areas with family members and others, allowing seniors to age in place as they require more care.

New Law Effective January 1, 2019

As of January 1, 2019, homeowners who created accessory dwelling units (ADUs) without the required building permits may have the opportunity to bring their ADUs into compliance. For ADUs that were constructed without building permits, local building officials now have the option to inspect an ADU and apply the building standards that were in effect at the time the unit was constructed.

This Bill: SB 1226 (Bates), adds Section 17958.12 to the California Health and Safety Code, and with the application of appropriate building codes, may allow issuance of a building permit for the residential unit.

NOTE: Changes to ADU laws effective January 1, 2021, further reduce barriers, better streamline approval processes, and expand capacity to accommodate the development of ADUs and junior accessory dwelling units (JADUs).

  • How much will my ADU cost?
    Since the size and construction of each ADU will differ, it is impossible to estimate the cost of your ADU. The cost per-square-foot of an ADU is likely to be the same as any other new residential construction; builders and architects can give you rough estimates.
  • My lot seems too small or unusual. Can I still build an ADU?
    Almost every lot in LA is unique, so this guidebook addresses the most common conditions. There are various types of ADUs that work on different lots. For example, if a detached ADU will not fit in your backyard, you might attach a new unit to your current house. If the garage behind your house is inconveniently located, you could demolish and rebuild it with an ADU above. Sketch your ideas as suggested in the guidebook, and talk them over with the Dept. of Building and Safety.
  • Must the homeowner live on the property?
    No, both the existing house and the ADU can be rental units.
  • Is an ADU subject to the Rent Stabilization Ordinance?
    If you add an ADU to your home, you can rent one or both of the units. If your home was built before 1979, one or both of the units may become subject to the City’s Rent Stabilization Ordinance (RSO). To determine if an ADU triggers the RSO on your property, call (866) 557-7368. For more information about the RSO, visit

Can I add an ADU to my Home?

Laws regarding ADUs are meant to widen the range of housing types to increase the housing supply for low-income Californians. The intent is to allow as many ADUs as possible with community safety and standards in mind. So, many residential properties will qualify. Because every lot is unique, you should work with a professional to determine if, and what type of ADU will work for your property.
