Navigating the Maze: A Guide to Retaining Wall Permits in St. Louis

Table of Contents

Retaining walls are valuable additions to St. Louis properties, but before you embark on your project, understanding the permitting process is crucial. Here’s a breakdown of what you need to know about retaining wall permits in St. Louis:

Do I Need a Permit?

The necessity of a permit for your retaining wall depends on two key factors:

Height: In the City of St. Louis, retaining walls exceeding 4 feet in height typically require a building permit. St. Louis County regulations might differ, so check with your county office for specific guidelines.

Location: Even if your wall is under 4 feet tall, a permit might still be needed if it’s located near property lines, easements, or public rights-of-way.

Where to Obtain a Permit

City of St. Louis: Permits are obtained through the City of St. Louis Building Division. You can find information and applications on their website  or by contacting them at (314) 622-4800.

St. Louis County: Contact the St. Louis County Department of Public Works for permit information and applications. Their website offers details and downloadable forms. You can also reach them at (314) 982-3211.

Required Documents

The specific documents needed for your permit application can vary, but  generally include:

Completed application form

Detailed site plan showing the location and dimensions of the retaining wall, property lines, and existing structures.

Construction drawings illustrating the wall’s design, materials, and foundation details. (For complex walls, engineering drawings might be required.)

Proof of property ownership

Permit Fees and Costs

Permit fees in St. Louis vary depending on the wall’s size, complexity, and location. Contact the relevant permitting office for an accurate fee estimate.  Keep in mind that additional costs might be involved, such as:

Engineering fees: For complex retaining walls, hiring a professional engineer to create construction drawings might be necessary.

Surveying fees: A land surveyor might be needed to accurately measure your property and create a detailed site plan.

Using a Retaining Wall Cost Calculator:

While online retaining wall cost calculators can provide a rough estimate, they might not account for all the variables that impact the final cost. These variables include:

Materials: The type of material used for the wall (concrete blocks, natural stone, treated wood) significantly impacts the cost.

Wall size and complexity: Larger and more complex walls naturally cost more than smaller, straightforward designs.

Labor costs: Labor rates can vary depending on your location and the contractor you choose.
