NO-PLAN MECHANICAL PERMITS (Including Mail-in, Fax, and E-permitting through Permitting Portal ACA) No-Plan Mechanical Permits are permits issued without the need for plans. These permits are issued and paid for electronically with no personal interaction with employees. The online system is accessible through the Permitting Portal found on the Department of Transportation and Public Works website page at https://stlouiscountymo.gov or may be accessed directly through https://aca.stlouisco.com/CitizenAccess/Default.aspx. You may also submit a No-Plan Mechanical Permit by using the fax system (314-615-8701). Note that the fax system is only available to companies having money in their escrow account to cover the permit fee. Examples of the types of permits that can be typically issued as No-Plan Mechanical Permits are as follows: 1. Repairs to mechanical systems and equipment; including, but not limited to, the replacements identified within this document. Note: Permits are not required for ordinary repairs for the purpose of maintenance and service. This includes items such as the repair or replacement of any minor part of a piece of equipment that does not alter the approval of the equipment, the replacement of piping within heating or cooling equipment, replacement of leaking or defective valves, fittings or connections of system components, changing of belts, parts, filters and lubrication of equipment, recharging, testing and balancing of equipment and similar service work. 2.

Replacement of refrigeration equipment and/or associated piping including freezers, walk in coolers, evaporators and condensing units. The equipment and/or associated piping must be of the same nominal capacity and size, the same type of equipment and in the same location as the existing equipment. 4.
