Hazardous Materials Construction Permitting
Plan Submittal Process:
If your project involves hazardous materials and/or hazardous waste, approval from the Fire Department, and permit issuance is required prior to beginning work. Construction, demolition or removal plans may be submitted to the Hazardous Materials and Environmental Services Unit via the following methods:
1). Submission Directly to the Fire Department for a Fire Department Permit:
Construction, demolition or removal projects that do not require Building Department review and/or approval should be submitted directly to the Fire Department at 455 East Calaveras Boulevard, Milpitas, CA 95035.
To submit plans directly to the Fire Department, complete the Milpitas Fire Department Project Transmittal Sheet, available at the above address, showing receipt of payment by the Milpitas Finance Department, for the appropriate amount specified on the project transmittal sheet and submit it along with two complete sets of plans.
2). Submission to the Building Department for a Joint Building and Fire Department Permit:
Construction, demolition or removal projects requiring Building Department review and/or approval should be submitted to the Building Department located at City Hall at 455 East Calaveras Boulevard, Milpitas, CA 95035.
Plans submitted to the Building Department must be accompanied by the following completed documents:
- Building Permit Application,
- Bay Area Air Quality Management District & Hazardous Material/Waste Disclosure form,
- Sewer Needs Inquiry form, and
- Milpitas Fire Department Transmittal Sheet for Building Permits Requiring Fire Department Review.
Plan Submittal Guidelines:
Please review our list of Forms and Guidelines to determine whether any of these forms may be used to assist in the preparation of your plans. Following the guidelines and providing the necessary information at the time of plan submission will assist in the processing and review of your plans in a timely manner and may increase the probability of receiving an approval at the first submission.
In order to process your application as efficiently as possible, the information listed below, at a minimum, must accompany your submittal. Failure to include this information with your application may extend the plan review time and the time required to obtain a permit or approval.
