Preliminary Notice Requirements in Lyon County

If you're working on a construction project in Lyon County, Iowa, here's the most important thing to understand about preliminary notices: Iowa law REQUIRES you to send one. It's called the "Notice to Prime Contractor" and it must be sent within 30 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 Lyon County. Your first day on-site is March 1st.

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

You have 90 days from last material furnished or labor performed to file. File within this window to keep your lien rights protected.
