“One thing I tell every ADU client: the time to add a second bath is during construction, not after. Roughing in a second bathroom adds $4–6K during construction. Adding one after the ADU is complete costs $18–30K in demo, new permits, and finished work. If there's any chance you'll want it, do it now.”
Walk the lot with your contractor before finalizing any ADU footprint. Access paths for concrete trucks, excavation equipment, and material staging dramatically affect construction cost on tight urban lots. A footprint that looks fine on paper may require costly hand-work or street staging permits in practice.
The most common adu construction mistakes in Encino are: selecting a contractor based on price alone without verifying CSLB license and insurance, approving change orders verbally rather than in writing, and starting work before permits are issued. All three create financial and legal exposure that's avoidable with careful contractor selection and contract management.
