Duplication of Plans During Shelter in Place

Building plans that the Department of Building Inspection maintains are public records open to the public for viewing and reproduction; however, the California Health and Safety Code prohibits the duplication of the official building plans, or documents such as reports and calculations that accompany these plans, without meeting the following criteria.

California Health and Safety Code Chapter 10: Building Records

Section 19851.

(b) Any building department of a city or county, which is requested to duplicate the official copy of the plans maintained by the building department, shall request written permission to do so from the certified, licensed, or registered professional, or his or her successor, if any, who signed the original documents and from (1) the original or current owner of the building or (2), if the building is part of a common interest development, from the board of directors or other governing body of the association established to manage the common interest development.

NOTE:  During Shelter in Place, plans are not available for viewing. We are providing copies of full plan sets requested following the Duplication of Plans process outlined below. 

To start the Duplication of Plans process, please check our website for permit history from 1983 to present to determine the permit application and scope of work you need. 

If you find what you are looking for, please complete the Records Request Form found on our website @ and email it to to verify that there is a record of the issued plans. Once we verify that we do have the plans available, we will ask you to email us a copy of the Notarized Affidavit of Owner and a completed / signed Applicant’s Declaration for our review

After our review and if the affidavit matches City records, we will ask you to mail us the original Notarized Affidavit of Owner and the original Applicant’s Declaration along with payment for the number of plan sets required, mailing fees, and prints. We cannot start the process without these two documents and payment. Once these documents and payment have been received, we will either send the letters to the design professionals or print the copies if no design professionals signed or stamped the plans. Design professionals have up to 30 days from the date the certified letter is mailed to respond to the request.  

If the records you are looking for are prior to 1983, we will ask that you send us the records request form for us to do research for older records.

Mailing to design professionals $6.90 per certified letter
