The Building and Safety Division issues permits and consults and advises architects, engineers, designers, and others. The division also reviews all building plans for compliance with code requirements and makes periodic inspections during the course of construction. 

Building Permits

Building permits are issued based on the current edition of the California Building Codes and local City amendments; encompassing building, electrical, mechanical, plumbing, sewer work, state energy requirements; and state accessibility laws. These codes are enforced to protect you and your property investment. The permitting process ensures that your project proceeds according to safe building practices and can offer assurances that contractors are properly licensed to perform the work.

Online Permit Scheduling 

The City of Lancaster, in partnership with Accela, is now expanding the types of permits available for online permitting to the following: residential rooftop solar, water heaters, mechanical, electrical, plumbing, signs, and residential standard patio covers. Citizens who are interested in applying for any of these permits can simply register for an account. The account registration not only enables the permit application process to begin, it also allows applicants to monitor their status along the permitting process.

To register an account and begin the permit process, citizens and solar providers can access the new Citizen Access Portal at: https://aca.accela.com/lancaster.

Please note that a SIGNED Building Permit Declarations document must be uploaded before a permit can be issued online. You may download the Building Permit Declarations document here. Once the permit has been issued, the system also provides the capability for the online scheduling of inspections.

Plans for projects complying with these toolkits are eligible for expedited “over the counter” review, or you may submit your application and plans online for next business day review and permitting at https://aca.accela.com/lancaster.
