Asbestos, lead and demolition work in St. Charles, Missouri

Who regulates asbestos work in St. Charles, Missouri?

Missouri DNR does. Its Air Pollution Control Program regulates asbestos demolition, renovation and abatement across the state, and we did not find a separate local asbestos program for St. Charles. Confirm the filing steps with DNR before you set a start date.

The key rule: DNR requires notification at least 10 working days before crews begin a demolition or abatement project on a regulated structure. A demolition notice is required even when no asbestos is found. DNR takes notices by email at AsbestosNotifications@dnr.mo.gov, and its phone is 573-751-4817.

Most single-family homes are exempt. Commercial buildings and some residential structures are covered. When an inspection finds 160 square feet, 260 linear feet or 35 cubic feet or more of regulated material that demolition or renovation will affect, a Missouri registered asbestos abatement contractor must remove all of it. Advanced Environmental Services (AES) holds Missouri DNR contractor registration 27-06-0640. Learn the terms: NESHAP and regulated asbestos-containing material.

Do I need a demolition permit in the City of St. Charles?

Yes, plan on one. The City of St. Charles has a Demolition Permit Information page, and it tells owners to schedule a post-demolition inspection with Community Development when work is finished. Call the city before you hire crews, because permit steps can change.

We have not confirmed whether St. Charles County has a separate permit for work outside city limits, so check the address first. Permits and asbestos notices are separate steps. You may need both, and the asbestos notice has its own 10 working day clock. For the permit itself, check with St. Charles County or the City of St. Charles directly.

AES lists demolition, interior demolition and building demolition as services.

How old are the buildings in St. Charles, Missouri?

It is a mixed market. In the city, about 40.0% of homes were built before 1980 and 28.1% before 1970, from 33,094 housing units counted in the 2024 American Community Survey. In St. Charles County as a whole only 24.7% are that old, because newer subdivisions dominate.

So do not assume a St. Charles, Missouri address is new, and do not assume it is old. Check the year built. Homes from the 1960s and 1970s can still have vinyl floor tile, pipe wrap and old paint. Our guide on asbestos in older St. Louis homes lists the usual places, and the same materials appear here.

Older commercial and industrial buildings that change use are where a survey pays off most. An asbestos survey samples suspect materials before work starts, so the plan and the notice match what is in the building. AES offers an asbestos survey and asbestos testing.

What about lead paint in St. Charles homes?

For homes built before 1978, assume lead paint until a test says otherwise. The Census cannot count 1978 exactly, so use the build year on your deed or permit record. Missouri DHSS says anyone performing lead abatement strategies must be licensed by the department.

Do not sand, scrape or burn old paint yourself. Read lead-based paint and our lead paint in pre-1978 homes guide. AES lists lead abatement as a service.

Are there Superfund sites in St. Charles County?

Yes, two. Missouri DNR’s National Priorities List page shows the Weldon Spring Former Army Ordnance Works and the Weldon Spring Quarry/Plant/Pitts (USDOE) in St. Charles County. A listing covers a defined site, not the county.

For most owners this is background. It matters if you buy land at or near a listed site. Ask for a records review and, if needed, soil testing. AES offers soil contamination testing and soil remediation. We do not publish local PFAS results for St. Charles, Missouri. If you need testing, see PFAS testing.

How do I plan a St. Charles, Missouri project from start to finish?

Work in order: confirm the building’s age, survey it, file the state notice, get the city permit, then schedule abatement and demolition. The order matters because the 10 working day notice period and the permit run on separate clocks.

1. Confirm the build year. Use the deed or county record. It tells you how likely asbestos and lead paint are.
2. Order a survey. A certified inspector samples suspect materials. Results set the scope.
3. File with Missouri DNR. Notice goes in at least 10 working days before crews begin on a regulated structure.
4. Get the city permit. Ask Community Development what the demolition permit needs.
5. Schedule abatement, then demolition. Regulated material comes out first.

The AES office is about 25.9 miles from Main Street in St. Charles, Missouri, about 38 minutes without traffic. That is an OSRM free-flow estimate, so allow more at rush hour. See St. Louis County for a similar process with a county office, and read our guide to Missouri demolition and renovation asbestos rules.
