Most of the ADU Standard Plans have been pre-approved with various options. Some customization is possible, such as changes to window and door types and sizes, colors, etc. Approved standard plan floor plans can also be rotated.

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.

One-time Approval. This approval is granted for fixtures and equipment that are custom made or installed at a specific job site. The evaluation and testing can often be performed at the location where the fixture/equipment is installed. Application for this type of approval may be filed by the building owner, installer, vendor, or manufacturer. The approval is for one time and for a specific location, and it cannot be used for another installation.

General Approval/Laboratory Approval. This approval is granted for fixtures and equipment to be used anytime and anywhere within the City. The testing and physical evaluation are usually done in an approved laboratory, unless a suitable site visit is prearranged. Application for this type of approval shall be filed by the manufacturer.
