Your top ADU questions answered
Answers to your most common ADU building questions.
No. A private assessment or condition report does not replace inspections performed by the permitting authority.
Share the building type, location and any prior reports. The team can discuss the appropriate inspection scope and professional requirements for your property.
Inspection, repair design and construction should be separately identified in the agreement. Ask which services are included and what requires additional authorization.
