What to expect during ADU construction
Active ADU construction means equipment access, material staging, and inspection holds between major phases. Neighbors and household routines are part of the plan.
What to expect during ADU construction
This guide is for homeowners whose permits are approved and construction is about to start. The ADU construction service page explains how Artbrick builds ADUs. Knowing the build phases helps you prep the site and set household expectations.
Homeowners describe ADU builds as louder and dustier during foundation and framing, then more predictable during interior finish. Access for concrete, lumber, and deliveries should be cleared before mobilization.
Living on site during an ADU build is possible but requires realistic expectations for noise, parking, and temporary loss of yard space. Inspection delays are outside contractor control but should be communicated when they affect the schedule.
Build phases from site prep to punch
Build phases
- Site prep Layout, excavation, utilities stubbed, access protected.
- Foundation Footings, walls, drainage; inspection before backfill.
- Framing and shell Structure, roof, windows, weather barrier.
- MEP rough-in Plumbing, electrical, HVAC; insulation and inspection.
- Interior finish Drywall, cabinets, tile, flooring, fixtures, punch.
Selection deadlines for windows, doors, fixtures, and cabinets still apply on ADU projects. Late selections push interior finish the same way they do on a kitchen remodel.
Notify neighbors before major concrete pours or long framing days. Weather holds are normal in winter. Tarps, drainage, and rescheduled pours protect quality; rushing concrete in freezing rain creates problems that show up years later.
Homeowner prep
- Clear access path for deliveries and equipment
- Mark sprinklers and utilities; protect landscaping if needed
- Expect noise during foundation and framing
- Plan for inspection scheduling delays
- Keep fixture and finish selections on agreed deadlines
- Secure pets and designate a single site contact for daily questions
ADU construction FAQ
Can I live on site during ADU construction?
Often yes, but expect noise, parking limits, and temporary loss of yard space. Foundation and framing are the loudest phases.
What slows ADU construction that homeowners control?
Late selections for windows, doors, fixtures, and cabinets. Clear access paths and on-time decisions keep the schedule honest.
How do inspection delays affect the ADU schedule?
Inspection delays are outside contractor control but should be communicated when they affect the next phase.
Should I notify neighbors before construction starts?
Yes. A posted contact number and clear site hours reduce friction before major concrete pours or long framing days.
