Reviewing architectural design for BC Building Code compliance as part of the building permit process ensures that any issues are addressed early, to minimize impact on design goals and ensure timely processing of the building permit application.

Code compliance reports demonstrate the approach to compliance with codes, standards, and regulations. Code compliance drawings further illustrate this compliance, and include the location of fire separations, travel distances, occupant load, exit capacities and any building code concepts applicable to the project.

The City of Vancouver, and the City of Surrey, offer the Certified Professional program as an alternate to the traditional Building Permit Process. A Certified Professional completes the reviews and inspections typically performed by the city building department and acts as a single contact between the project team and the authority having jurisdiction. 

This program can benefit the project through time savings by allowing for staged building permits, where excavation can proceed before the full building permit is issued. The city review phase of a CP project can take just a few weeks, compared to the usual months. The CP process is available for both renovations and new buildings, and we’ve worked through it for tenancies ranging from offices and apartments, to restaurants and museums.
