Does the City have copies of my Building, Plumbing, and Electrical plans?
The City may have a copy of your plans for review at City Hall. Be aware that plans rarely provide specific detail as to the location of individual electrical circuits or plumbing/sewer lines.

Contact the building division for availability and specific restrictions (909) 394-6260.
How are building permit fees calculated?
Permit fees are designed to try and offset the actual cost of review and inspection of the specific work proposed and therefore calculated by one of the following:– Valuation of work as determined by a standardized per square foot cost table.– Valuation based on the fair market value of labor and materials.– Per item as is the case with plumbing and electrical permits.
Fee schedules are available at the Building Division counter.

How long does a plan check date from the date of application?
Depending on the size of the project, plans are normally returned within 14 working days for small additions and minor tenant improvements. New houses and large commercial work may take 30 to 45 days as the Plan Review time is proportional to the scope of work and complexity of the project.
How many sets of plans and/or calculations are needed to submit for a plan check?
A minimum of two sets are required for minor projects; three sets of plans and two sets of calculations for more complex work; and four sets of plans required if project requires Fire Department review. For more information, contact the Building Department at (909) 394-6260.
