Frequently Asked Questions

Question 1: How much does it cost to build an ADU in Southern California?

ADU costs in Southern California vary depending on size, design, site conditions, and city requirements. Most projects fall within a broad investment range based on square footage and finishes. During your consultation, we review your property and provide realistic budget guidance based on your goals.

Question 2: How long does the ADU process take?

The full process typically includes design, city approvals, permitting, and construction. Timelines vary by city and project scope, but most ADU builds require several months from planning to completion. We outline a clear roadmap during your consultation.

Question 3: Do I need special permits to build an ADU?

Yes. California has specific state laws that allow ADUs, but each city has zoning and permit requirements. Boss Homes manages the planning, permitting, and compliance process to ensure your ADU meets all local regulations.

Question 4: Can I rent out my ADU?

In most Southern California cities, ADUs can be rented long term. Short-term rental rules vary by municipality. During your consultation, we can review your city’s regulations and discuss income potential.

Question 5: How do I know if my property qualifies for an ADU?

Lot size, setbacks, utilities, and city regulations all play a role. The best way to determine eligibility is to submit your details so we can evaluate your property and discuss next steps.
