Business Licenses

All businesses wishing to operate in the City of Ladue are subject to the City’s licensing requirements as detailed in Chapter 50 of the City’s Code of Ordinances.

New businesses are required to apply and pay for a business license and occupancy permit prior to operation. Renewal business licenses are sent out in the first week of January for the applicable year and payment is due no later than March 1.  Per ordinance, penalties of 1% per month will apply to all payments after March 1.

There are different business types that are recognized in the code, and fees (and application forms) vary depending on the business type.  They include: Home based businesses (flat $50 fee), Financial institution businesses (flat $5,000 fee), Service businesses (square feet at $0.10 per square foot), Retail gross receipts businesses (sliding scale fee), and Trash hauler businesses ($12 per truck).

Most businesses must supply the appropriate license forms with notarized signatures and payment. Retail gross receipts businesses (including new businesses) must also supply a No Tax due letter from the Missouri Department of Revenue.  This letter can easily be obtained through their website at

All businesses operating in St. Louis County are also required to register and obtain a merchant’s license through the Assessor’s office.  Their web site is:
