Commercial Plan Requirements
The following lists the minimum requirements for a commercial project. In unique situations, additional materials may be necessary. Geotechnical and soils reports are required for new buildings.
Who May Prepare Plans
State law regulating the architectural and engineering professions describes who may prepare plans for buildings. View the Who May Prepare Plans (PDF) for additional information.
Signature on Plans
State law requires that the person who prepared the plans must sign all pages. The city building code also requires an address and telephone number of the person who prepared the plans. Please inquire at the Building and Safety Division if you have any further questions concerning submittal requirements for a specific project.
Please contact the Building Division prior to making any improvements to an existing property to ensure compliance with ADA standards and avoid lawsuits. There are both federal and state disability requirements of which the California codes tend to be more stringent.

On January 1, 2010, the California Energy Commission's 2008 Building Energy Efficiency Standards for Residential and Nonresidential Buildings (PDF) and the 2008 California Residential Energy Compliance Requirements for Cool Roofs Handout (PDF) went into effect.
On January 1, 2011, the California Green Building Standards Code (PDF) went into effect. The code sets targets for energy efficiency, water consumption, dual plumbing systems for potable and recyclable water, diversion of construction waste from landfills and use of environmentally sensitive materials in construction and design, including eco-friendly flooring, carpeting, paint, coatings, thermal insulation, and acoustical wall and ceiling panels.
The new codes include new publications: the Green Building Standards Code (CALGreen) and the California Residential Code, which will require automatic fire sprinklers in all new single-family homes in California. Download a sample Construction Waste Management Plan (PDF).
