Note: Any incomplete information may cause a delay in reviewing the plans or issuing a building permit. There may be additional items required that are specific to certain areas. These items will be requested during the plan review process. For example, fire suppression systems. If you have any questions about submitting an application, please contact one of the plans examiners in the Building Division. Individual permits for electrical, plumbing and mechanical are not required since the Building Permit includes these trades. However, construction meters require a separate permit.
