Frequently Asked Questions

What is the commercial architecture process?

Commercial projects follow the same six phases as residential work — consultation, schematic design, design development, construction documents, permitting, and construction administration — but with additional coordination of code compliance, ADA accessibility, and commercial mechanical systems.

How long does a commercial architecture project take?

Timelines vary by project size. A commercial renovation may complete design and permitting in 4 to 6 months; a ground-up commercial building typically requires 9 to 18 months from design start to permit approval.
