IS A DETACHED ADU RIGHT FOR YOU?
When Detached ADUs Are the Right Fit
A detached ADU is often the best fit when the property has usable yard area and the owner wants stronger privacy, a separate entrance, independent outdoor space, and clear separation from the primary home. It can support multigenerational living, long-term rental housing, a guest residence, or a flexible home that changes with the family over time.
IDEAL FOR
Nearby Independence for Family: A parent or adult child who needs nearby independence.
Long-Term Rental Housing: A long-term rental with a separate address and entry.
Independent Guest Residence: A guest residence with its own kitchen and bathroom.
Future Downsizing: A future downsizing option while retaining the main home.
High-Performance Construction: A high-performance or fire-resilient backyard build.
Property Feasibility
Property and Feasibility Review
Before design begins, Builtech evaluates the property as a complete system. The review identifies what appears feasible, what requires confirmation, and which decisions have the greatest effect on cost, schedule, and approval.

FAQ
Common Questions About Fire-Resistant Building in California
Straight answers to the most common questions homeowners ask before they begin.
What is home hardening?
Home hardening means reducing the features that make a structure susceptible to ignition from wind-blown embers, radiant heat, and direct flame contact. Rather than generic remodeling, we specifically target vulnerable areas like roofs, vents, windows, and exterior assemblies.
