Standard plans are intended to serve as a base design that has already been reviewed by the Department of Building and Safety for Building Code Compliance. However, each property is unique, and modifications / customizations to a pre-approved standard plan may be necessary. Any customization of a pre-approved standard plan must be completed by the plan’s owner. Please note that design changes may result in additional costs and could result in additional permitting review timelines, as revised portions of the plan will require City review.
