Common questions from general contractors and project managers.
What types of ADU projects do you handle?
We work on all ADU types including detached new construction ADUs, garage conversion ADUs, and attached ADU additions. Our crews are experienced with the compact spaces and site constraints typical of ADU projects.
How long does drywall work take on a typical ADU?
Most ADU drywall projects take 1-3 weeks depending on size and finish level. We coordinate closely with the GC to minimize disruption and complete work efficiently while maintaining quality standards.
Do you handle garage conversion ADUs?
Yes, garage conversions are common for our teams. We work with the existing structure, coordinate insulation and utilities, and deliver clean finish work appropriate for conversion to living space.
Can you work around homeowners on occupied properties?
Absolutely. We understand ADU construction often occurs on occupied residential properties. Our crews maintain clean work areas, minimize noise where possible, and coordinate schedules with homeowner needs.
