Incomplete applications will not be accepted, and corrections will be asked of the applicant before intake of any documents or the start of review. All documents must have clear and crisp print, be free from stains and smudges, and be legible.  Images and photo attachments will not be accepted.  It is the applicant's responsibility to have all items required.

Plan Check Deposit

Correction Comments

Notice to Contractors

All contractors performing work within the Town of Loomis must have a Town of Loomis business license.  Please visit the Planning Department's business license page to learn how to obtain a Loomis business license and submit applicable fees.  Building permits will not be able to be processed if a contractor does not have a Town of Loomis business license, or if the contractor's license is not in good standing with CSLB.

Authorization Letter

If the applicant is not the contractor or property owner, a signed letter authorizing the individual to apply on the contractor or property owner's behalf is required to obtain a building permit or business license.
