Commercial Building Construction Division

What we do

The Commercial Construction program is responsible for ensuring public safety through the effective application of commercial building, structural, electrical, mechanical, fire safety, accessibility and sustainability conservation codes and standards. This is accomplished through plan review and construction site inspections to facilitate compliance with approved plans and regulations. This program processes applications for and issues Building, Mechanical, Fire Protection and Electrical Permits. The program also handles construction complaints during natural (and other) disasters and assists in disaster recovery. If you don't find what you are looking for, reach out to the Customer Support and Outreach team through the online staff directory. For more information about commercial construction and building safety, check out the Permitting Services Podcast ( audio and video) on-demand.
