Missouri asbestos rules for demolition and renovation: who you notify and when

What are Missouri’s asbestos rules for demolition and renovation?

Missouri follows a federal rule called NESHAP, run by the Department of Natural Resources (DNR). For a regulated building, you inspect for asbestos first, file a notice at least 10 working days before work, remove regulated material if it reaches set amounts, and dispose of the waste properly. Rules are current as of October 2026.

The EPA says the federal rule is meant to minimize the release of asbestos fibers during activities involving the handling of asbestos. It requires a thorough inspection where demolition or renovation will occur, and notice to the delegated entity, often a state agency, before any demolition.

This guide covers the rules across the St. Louis region. For a plain-language look at the work itself, see our removal process guide. For permits, see our posts on the 10 working day notice and the St. Louis City permit.

Which buildings are covered, and which are exempt?

Commercial buildings and some residential ones are covered. Most single-family homes are exempt. DNR says the department regulates demolition and renovation of institutional, commercial, public, industrial or residential structures, with an exception for a single residential structure of four or fewer dwelling units.

The exemption has limits. DNR’s fact sheet says these are not exempt:

• Projects with two or more residential structures
• Two or more residential structures demolished as part of an urban or rural renewal or unsafe building program, regardless of how close they are
• Demolition of two or more mobile homes
• A structure used for any purpose other than residential, such as one converted from residential to commercial use or the reverse
• Any residential structure used in fire training exercises

The EPA states a similar principle. A house demolished as part of an urban renewal project, a highway project, or a development like a shopping mall is subject to the rule. So the question is not “is it a house?” but “what is the project?”

If you own a rental building, a church, a school or a small commercial building, assume the rules apply and ask. A catastrophic event such as a tornado or accidental fire that destroys a regulated structure calls for contact with DNR’s Air Pollution Control Program for guidance.

What does the inspection have to include?

A Missouri certified asbestos inspector must thoroughly inspect the structure, or the areas to be disturbed, before demolition or renovation. The inspector identifies all suspect materials, collects samples for lab analysis, and writes a report with amounts, locations, categories and condition, plus lab results and chain of custody.

Why it matters: the report drives everything else. It decides whether you reach the thresholds, what is removed, and what goes into the notice. St. Louis County adds that all regulated structures must be inspected by a certified asbestos inspector before renovation or demolition, and that the inspection report must be attached to the notice.

DNR also says that if a structure is structurally unsound, the inspector should inspect everywhere it is safe to do so, and the report must say which areas were not inspected. Those areas need special handling during demolition.

Our asbestos survey service covers this work. A “demolition survey” is the most intrusive kind, because it must reach every area the work will touch. The glossary entry on the asbestos survey explains the types.

What are the three categories of asbestos material?

DNR sorts material into friable, Category I non-friable and Category II non-friable. The category and the work method decide whether the material is “regulated.”

Regulated material is called regulated asbestos-containing material, or RACM. A note on vapor barriers: DNR says any asbestos-containing vapor barrier on resilient floor coverings such as sheet vinyl or tile is considered friable.

One practical result: floor tile and linoleum are Category I. DNR generally recommends removing them before demolition, because demolition can easily turn them into regulated material, and leaving them in place can add to asbestos waste and the cost of disposal.

What are the threshold amounts?

160 square feet, 260 linear feet or 35 cubic feet. If an inspection finds that this much regulated material or more will be affected, all of it must be removed by a Missouri registered abatement contractor. The EPA uses the same numbers: below them, the federal rule does not require regulated material to be removed before demolition or renovation.

A few points on the numbers:

• They apply to regulated material that will be affected, not to all asbestos in the building.
• The EPA phrasing is “less than 260 linear feet, 160 square feet, or 35 cubic feet” for the no-removal exception.
• DNR says that if threshold quantities of Category II material will be affected, it must be removed first, in a way that does not crush it.
• Below the thresholds, a project may still need a notice. In the City of St. Louis, smaller abatements of 10 square feet, 16 linear feet or 3 cubic feet and up have a lower-tier notification.

Registered contractors may only use workers certified by DNR. Check the company on the DNR registry before you hire.

Who do I notify, and when?

Notify the right office at least 10 working days before work starts. DNR is the default across Missouri. The City of St. Louis and St. Louis County run their own programs under agreements with DNR. Always check with the local office before you file.

The notice must be filed by the owner or operator, and DNR says the owner and any contractors share the duty to make sure it is done. The notice goes with a copy of the inspection report and lab results. DNR sends a notice-of-receipt letter that lists any deficiencies.

The wait is built to let regulators inspect. DNR says the period gives the department time to inspect the project and ensure it complies. If you pick a start date less than 10 working days out, the County’s form instructions warn: never enter a date that is not at least ten working days after your postmark date, unless granted a waiver by the department.

What are the local rules in the City of St. Louis?

In the City of St. Louis, the Department of Health is the delegated authority for asbestos and demolition notifications and inspections, under an agreement with DNR. Demolition, renovation and abatement projects must be reported on the STL City Permits website. The City also publishes fees.

As of October 2026, the City page lists these fees among others:

The City accepts business checks or money orders at 1520 Market St., Room 4051, on weekday mornings; credit cards are not available, per the City page. Fees change, so confirm on the City page first. The City also cites Ordinance 71332 for abatement projects above 10 square feet, 16 linear feet or 3 cubic feet. Building permits are separate, so see our St. Louis City permit post and our St. Louis page.

What are the local rules in St. Louis County?

St. Louis County’s Department of Health, Air Pollution Control Program, handles asbestos NESHAP notices. The County’s form instructions repeat the 10 working day rule and say the inspection report must be attached to the notice. Completed forms go by mail to the address in the table above.

The County page we read gives the process but no fee. We have not published a County demolition fee, because our sources disagree on the amount. Ask the County for the current fee before you file. DNR’s fact sheet lists the County Health Department phone number as 314-615-8924. See also our St. Louis County page.

What about St. Charles County, Missouri, and Columbia?

DNR is the asbestos office in both places, because neither is one of the local agencies DNR lists. DNR names three local agencies with enforcement agreements: Kansas City, St. Louis County and the City of St. Louis. A fourth, Springfield, inspects but does not process notices.

For St. Charles County, Missouri, check with the County before you demolish: it issues demolition permits through its Community Development department, which is separate from the asbestos notice. We could not read the County’s permit page for fees or asbestos wording, so we do not state any. See our St. Charles page.

For Columbia, the Boone County FAQ says the County does not require a demolition permit, but suggests checking with the Boone County Fire Protection District for any controlled burn of a structure and with the Boone County Health Department for any asbestos removal. The City of Columbia has its own permit process, so ask the city. DNR notification still applies to regulated projects statewide. See our Columbia page.

What about waste disposal and emergencies?

Asbestos waste from regulated projects must go to an approved sanitary landfill or transfer station through a registered abatement contractor. The EPA says it must be sealed in leak-tight containers while wet, labeled, and taken to a landfill qualified to receive it. Non-friable material that is not made regulated is still solid waste.

Emergencies have special paths. DNR can waive the 10 working day wait where a structure is in danger of imminent collapse and a state or local government agency has ordered it demolished. Notice should go in as early as possible, and no later than the next working day, with a copy of the government order. Alternate provisions may apply in other emergencies, so contact DNR’s Air Pollution Control Program.

Our asbestos disposal page explains this side. If tanks or chemicals are also involved, see hazardous material disposal and the guide on demolition from survey to debris.

What happens if I skip a step?

Skipping the notice is a violation. DNR says failure to submit the notification is a violation of its requirements.

Beyond fines, skipping the inspection puts workers and neighbors at risk and can force costly rework when someone finds asbestos halfway through. AES says it has never had a citation from any government regulatory agency, including the EPA or OSHA, and has a good working relationship with St. Louis City Air Pollution Control, the St. Louis County Department of Health and Missouri DNR. We plan the notice dates into the schedule from the start.
