Common Questions
- Do Portola Valley permits slow projects down?
Most timelines are predictable once plans are set. We handle submittals, track comments, and sequence inspections so progress continues as selections and deliveries land.

Starts depend on permits, selections, and vendor timelines. During preconstruction we share a milestone schedule for your exact scope.
- Do you handle permits and inspections?
Yes. We prepare submittals, track comments, and schedule rough and final inspections in sequence to maintain momentum.
- Can we live at home during construction?
Often yes. We use containment, protection, and set clear work hours. For kitchens and single baths, we plan temporary options when possible.
- How do you keep budgets predictable?
Clear scope, early selections, and written vendor holds. We use a fixed contract with a 10 percent contingency cap and a 30-day material quote guarantee.
- Will you work with our designer or architect?
