📌 What Is a Commercial Buildout

A commercial buildout transforms a raw or existing commercial space into a fully functional, code-compliant business location. It includes design, permits, construction, and final inspections. In NYC, this process is more complex due to strict Department of Buildings (DOB) regulations and compliance requirements.

A commercial buildout is the end-to-end process of turning an empty or outdated space into a ready-to-open business.
