Preliminary Notice Requirements in Washington County

If you're working on a construction project in Washington County, Missouri, here's the most important thing to understand about preliminary notices: Missouri law REQUIRES you to send one. It's called the "Notice of Intent to File Lien" and it must be sent within 10 days of when you first start working or delivering materials to the project. Sending it on time keeps your lien rights active and all your options open.

Let's say you're a subcontractor hired to do HVAC installation on a new building in Washington County. Your first day on-site is March 1st.

It's not confrontational — it's standard paperwork that protects your right to get paid.

All preliminary notice requirements in Washington County come from Missouri state law (MO Rev. Stat. §§ 429.010 et seq.). The rules are the same across every county in Missouri — but when it comes time to actually file a mechanics lien, you'd file it at the Washington County Recorder's office.
