Preliminary Notice Requirements in St. Mary's County

If you're working on a construction project in St. Mary's County, Maryland, here's the most important thing to understand about preliminary notices: Maryland law REQUIRES you to send one. It's called the "Notice of Intention to Claim Lien" and it must be sent within 120 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 St. Mary's County. Your first day on-site is March 1st.
