Iowa Mechanic Lien Enforcement Deadlines

Private Works — 2-Year Suit Deadline

Under Iowa law, a mechanic lien claimant must commence suit to enforce (foreclose) the mechanic lien within 2 years from the expiration of the 90-day mechanic lien filing period. This means the total time from last furnishing to the suit deadline is approximately 2 years and 90 days.

The 2-year enforcement period is relatively generous compared to many states. However, claimants should not delay in pursuing enforcement, as the property may be sold or other mechanic liens may be recorded during the waiting period.

Public Works — Bond Claim Filing (30 Days After Final Settlement)

Under Iowa Code §573.1 et seq., bond claims on public works projects must be filed within 30 days after the final settlement between the public entity (state, county, or municipality) and the general contractor.

The 30-day deadline from final settlement is a strict requirement. Claimants should monitor the progress of the project and the anticipated final settlement date to ensure timely filing of their bond claim.

Public Works — Notice Requirement for Bond Claims

Subcontractors and suppliers not in privity with the general contractor must have served written notice to the GC within 30 days of first furnishing labor or materials. This notice is a prerequisite to making a valid bond claim.

Even if the bond claim is filed within the 30-day post-settlement window, failure to have served the required preliminary notice to the general contractor may bar recovery on the bond.
