How do I apply for a building permit online?

Updated October 2026 · How we answer

Gathering what the portal asks for

Before you start, collect a short project description, the property address, the parcel or tax ID number, and the estimated cost of the work. Many portals also ask for contractor license numbers if someone else is doing the job. Having these details on hand keeps the application from stalling halfway through.

Plans usually need to be uploaded as PDF files. Simple projects may only require a sketch with dimensions, while larger ones often need stamped drawings from a designer or engineer. Check the department's file requirements before you scan anything.

• Property address and parcel or tax ID number
• Written scope of the work and estimated cost
• Contractor license number, if one is hired
• Plans in the file format the portal accepts

Submitting and tracking the review

After you submit, the department typically assigns a reviewer who checks the application against local code. Reviewers often send comments asking for corrections or clarifications. Respond through the same portal so the record stays in one place.

Most portals let you track the status and see messages from staff. Watch for requests to upload revised pages, since delays often come from unanswered comments.

Paying fees and receiving approval

Fees are usually paid through the portal by card or electronic check at the time of submission or once the application is accepted. Once approved, you can download the permit and print any required job copies. Keep the approved plans on site so the inspector can see them.

Some departments require a separate fee for each trade, such as electrical, plumbing, or mechanical work. Read the fee summary carefully before you pay.
