Maryland Notice Requirements

Private Works — Contractor Notice Requirements

Under Maryland law, contractors in direct privity with the property owner are not required to serve any preliminary notice or other notice before filing suit to establish a mechanic's lien. Contractors may proceed directly to filing a Petition to Establish and Enforce a Mechanic's Lien within 180 days of last performance.

While no notice is required, the contractor's petition must include 'all material papers' to support the mechanic lien claim. This streamlined process reflects the direct contractual relationship between the contractor and the property owner.

Private Works — Subcontractor Notice to Owner (§9-104)

Subcontractors and materialmen must serve a Notice to Owner of Intention to Claim a Mechanic Lien within 120 days of their last performance of work on the project. The notice must be sent by certified mail to the owner. §9-104.

Under Maryland law, 'subcontractor' means any party with a contract with a party other than the owner. This broad definition means that materialmen and suppliers who contract with the general contractor or other subcontractors are also considered subcontractors for notice purposes. Tier coverage may be limited accordingly.

Effect of Notice on Owner's Payment Obligations

Once the owner receives the Notice to Owner of Intention to Claim a Mechanic Lien, the owner may withhold funds from the contractor to cover the subcontractor's claim. This creates a powerful incentive for the contractor to resolve payment disputes.

The notice effectively puts the owner on alert that unpaid parties exist on the project and that funds should be reserved to satisfy potential mechanic lien claims.

Single-Family Residential Projects — Special Rules

On single-family residential projects where the owner is constructing their own residence, Maryland provides special protections for the homeowner. Any notice given after the owner has made payment to the contractor is ineffective to preserve mechanic lien rights to the extent of payments made before the notice was received.

This means subcontractors on owner-occupied single-family residential projects must serve their Notice to Owner as early as possible to preserve full mechanic lien rights. Delay in providing notice can result in loss of mechanic lien rights to the extent the owner has already paid the contractor.

Public Works — No Preliminary Notice Required

On Maryland public works projects, no preliminary notice is required to preserve payment bond claim rights. However, subcontractors and materialmen whose contract is with a subcontractor (not the prime contractor) must serve a Notice of Claim on the Bond.

Public Works — Notice of Claim on Bond (§17-108)

Within 90 days of last performance, a claimant whose contract is with a subcontractor must provide written notice to the principal contractor of their claim on the payment bond. §17-108. This notice is not required for claimants who have a direct contract with the prime contractor.

Payment bonds are mandatory for public contracts over $100,000. Contracts between $25,000 and $100,000 may have bond requirements imposed by the municipality, not to exceed 50% of the contract price. The bond must be in an amount not less than 50% of the total contract price.
