Whether you can build an ADU depends on your property type and local rules. For single-family properties, you can usually add one full-size ADU and one Junior ADU (JADU) up to 500 sq. ft., converted from inside your existing home. This means your property could have two extra units alongside your main house (Main House + ADU + JADU), though city rules may vary.
For multifamily properties, you can typically add at least two detached ADUs. State law sets the minimum, but some cities allow more. For example, under SB9 (the lot split law), you may be able to add two main homes and up to two ADUs, depending on lot size and local rules.
