- Detached ADUs up to 1,200 sq ft are allowed by right on most residential lots
- Garage conversions are generally approved without owner-occupancy requirements
- Junior ADUs (JADUs) up to 500 sq ft can be created within existing living space

Berkeley Home Remodeling & ADU: Frequently Asked Questions
How long does an ADU project take in Berkeley?
Most ADU projects in Berkeley take 5–9 months from design to completion, including permitting. Garage conversions are typically faster, running 3–5 months. Berkeley’s building department is generally responsive, and our permit specialists know how to submit complete applications that minimize back-and-forth review cycles.
Do I need owner-occupancy to build an ADU in Berkeley?
No. California law currently prohibits local governments from imposing owner-occupancy requirements on ADU properties through at least 2025, and Berkeley complies with this. You can build an ADU and rent out both units if you choose.
What is the maximum ADU size allowed in Berkeley?
Detached ADUs in Berkeley can be up to 1,200 square feet. Attached ADUs and garage conversions have size limits tied to the primary dwelling’s square footage. Our design team will assess your specific lot and zoning to determine the maximum allowable size for your property.
Can Golden Heights Remodeling handle Berkeley’s historic preservation requirements?
Yes. Many Berkeley Hills homes fall within historic overlay zones that require additional design sensitivity. We have experience working within Berkeley’s architectural review process and can design additions and ADUs that complement your home’s historic character while meeting all modern building codes.
What is the cost of a full home remodel in Berkeley?
Full home remodels in Berkeley typically range from $200,000 to $500,000+, depending on scope, structural changes, and finish level. Kitchen and bathroom renovations are the most common high-ROI components. We provide detailed, transparent proposals so you know exactly what you’re investing before construction begins.
Do you offer financing for Berkeley remodeling projects?
We can connect you with preferred financing partners who specialize in home improvement and ADU construction loans in the Bay Area.
