Pennsylvania deadline risk

Missing a Pennsylvania notice or lien filing deadline can eliminate lien rights. Run the calculator early and verify close calls.

Deadline Type	Timing	Details
Preliminary notice	30 days after first furnishing for subs/suppliers on projects over $1M	Notice rules can depend on role, project type, and contract chain. Send notices early when in doubt.
Mechanics lien filing	6 months after last work	Use this as a planning estimate and verify the filing trigger.
Enforcement	2 years after filing lien	Filing a lien is not the final step. Track enforcement deadlines separately.

Run the deadline check when materials are furnished, not when collections already become urgent.

Preliminary notice rules can change by role and project type. Treat the notice path as a required workflow check.

Use the calculator for operational tracking, then verify high-value or disputed claims with counsel.

Use the calculator with your invoice date to estimate the Pennsylvania deadline.
