Permit Process

Design Considerations

Important! Read the common Design Considerations before you create plans or start a project. These can affect the design, location, and permitting of the project. 

Get Ready to Apply

Who can apply? We recommend that the applicant be a licensed contractor. See Who Can Apply for a Building Permit for others who may apply. Whoever signs the building permit application is responsible and potentially liable for all activity under the permit. See Owner-Builders Beware!

SJPermits can help. At SJPermits.org, you can pay fees, schedule inspections, check the status of a permit, and find permit records and property information. An SJPermits account is required only if you are applying for an online permit or for projects that require Standard Plan Review.

Permit Fees

Find fee information and payment methods at Building Fees. 

Prepare the Permit Application Package

Who can prepare plans? While some plans may be prepared by anyone, we recommend working with professionals. Inaccurate plans will require resubmittals and more fees. Accurate plans save time and money. See Plans That Require an Architect or Engineer.  

Forms may require digital signatures. See Digital Forms & Signatures for help.
