Frequently Asked Questions
How much does it cost to build an ADU?
ADU costs vary depending on size, design, site conditions, and utilities. In Southern California most ADUs range between $150K and $400K. We provide project-specific estimates after reviewing your property.
How long does it take to build an ADU?
The construction phase of an ADU typically takes 6 to 10 months, depending on the size, scope, and complexity of the project. This timeline reflects build time only and does not include the design or permitting phase.
Can I build an ADU on my property?
Many single-family properties in California qualify for ADUs, but zoning, lot size, and access can affect placement. Our team can review your property and help determine eligibility.
Do you handle permits?
Yes. We guide homeowners through the permit process and work with the appropriate city departments to move projects forward.
Can I stay in my home during construction?
In most cases, yes. Many ADU projects allow homeowners to remain in their primary residence throughout construction, especially for detached units. We plan each project to minimize disruption as much as possible.
