For category 2 and category 3 building permits a mechanical plan is a general requirement for the permitting process. A mechanical plan should be submitted for all new commercial and residential construction or when installing, upgrading or altering an existing or new mechanical systems. This preliminary plan should be submitted to be reviewed in conjunction with the building plans.

Once approved, the plans will be initialed by the Building and Zoning Department and distributed to the applicant.



Mechanical inspections are conducted by the Building Inspector. These inspections are part of the permit fee and are no additional charge. If these inspections are not done at the appropriate time, the City can require the applicant to remove or redo any work that was not inspected. The applicant may also be subject to fines and other penalties. Any changes or deviations from the plans will be noted on the inspection form. The following inspection schedule is only the minimum number of inspections. The City reserves the right to inspect any development at anytime to ensure compliance with all development codes and procedures.
