Good News for Maryland Contractors

Maryland does not require a pre-lien preliminary notice. However, notice provisions may affect lien rights depending on the type of project. You still must file the lien within the deadline and in the correct recording office.

Commercial vs Residential

Does the Property Type Change Your Deadline?

Same 180-day deadline. Maryland's process requires a court petition — it is more formal than many states.

Common Mistakes

What Contractors Get Wrong in Maryland

1
Missing the 180-day deadline from completion or last work
2
Filing in the wrong circuit court — Maryland lien petitions go to circuit court, not a recorder
3
Not serving all required parties in the lien petition process
