Plans can be submitted at our facility in the Building Department lobby located in the main City Hall building.  We no longer issue permits over the counter  for plumbing or mechanical, they can be applied for online through our permit portal. 
All of our applications and building fee scheduled are available online. Please have your application completed when you arrive at the office. We do not provide paper copies of our permits in-house. Applications must be completed with owner or agent signature, trustee signatures on plans [Ord. 2153](if project modifies outside of home or lot) and two sets of signed and sealed plans.  All building permits require a $100 non-refundable deposit when making application. (Note: If application is for a new residence the deposit is $500)

The Building Department does not accept permits via email or fax. Your completed permit application should be accompanied by TWO sets of plan documents/construction documents. *Effective 1/25/2023, Per Section 118-2 Ladue Code of Ordinances a copy of the Bona Fide Contract will be required with all building permits and commercial plumbing or mechanical permits to show total project cost.
