Mechanic's Lien Deadlines & Notice Requirements in Maryland
At a glance
| Governing law | Md. Code, Real Property §§ 9-101–9-114; a lien is established through circuit-court proceedings (§§ 9-105, 9-106) |
|---|---|
| Who can claim a lien | Contractors with an owner contract and subcontractors contracting with others; qualifying building work, materials and listed services, subject to statutory value thresholds (§§ 9-101–9-103) |
| Preliminary notice | Subcontractor gives written notice of intent within 120 days after its own work or materials; for an owner-residence, full payment to the contractor before notice defeats that lien (§ 9-104(a)) |
| Deadline to file the lien | File circuit-court proceedings within 180 days after finishing work or furnishing materials; petition alone does not establish the lien (§§ 9-105(a), 9-106) |
| Notice of completion effect | The § 9-105(a) petition clock runs from finished work or furnished materials; § 9-104(a) separately measures subcontractor notice from that claimant’s work or delivery |
| Serving the lien on the owner | Court directs service of a show-cause order and petition papers, then gives the owner 15 days from service to respond (§ 9-106(a)(1)) |
| Deadline to sue to foreclose | Right to enforce expires one year after the establishment petition was first filed; claimant may petition to enforce or execute on a release bond in that period (§ 9-109) |
| Homestead/residential extras | For a single-family dwelling being built on the owner’s land for the owner’s residence, full payment before subcontractor notice bars the lien; any lien is capped by unpaid contract balance at notice (§ 9-104(a)(2), (f)(3)) |
Requirements one by one
Governing law and claimants
Real Property § 9-101 calls a person who contracts with the owner a contractor and a person who contracts with someone else a subcontractor. Section 9-102(a) permits a lien for a new building or an improvement reaching 15 percent of an existing building's value; it lists qualifying work, materials, equipment leasing and professional services. For qualifying tenant-ordered work, § 9-103(c) uses a 25 percent threshold and limits the lien to the tenant's interest. Section 9-102(d) also protects a bona fide purchaser who received title before a lien was established.
Subcontractor notice
A subcontractor must give the owner written notice of intent to claim a lien within 120 days after its work or materials (§ 9-104(a)(1)). On a single-family dwelling being built on the owner's land for the owner's own residence, § 9-104(a)(2) also requires that the owner had not paid the contractor in full before receiving notice. Even when that lien is allowed, § 9-104(f)(3) caps it at the amount the owner owed under the contract when notice arrived.
Court petition and owner response
Under § 9-105(a), a claimant files proceedings in the circuit court for the property's county within 180 days after work is finished or materials furnished. Section 9-106(a)(1) directs the court to review the petition and, if the lien should attach, issue a show-cause order served with the papers; the owner has 15 days after service to respond. Filing the petition starts that process but does not itself establish a lien. The same finished-work and furnished-materials events define the petition clock; § 9-104(a) gives the subcontractor's separate notice clock.
Enforcement
Section 9-109 says the right to enforce an established lien expires one year after the establishment petition was first filed. During that period the claimant may petition in the lien proceedings to enforce it or execute on a bond that released the property.
What trips people up
The one-year enforcement period runs from the initial petition, not the later court order establishing a lien (§ 9-109). A claimant waiting for the court's decision should track that original filing date.
Common questions
Does a filed petition immediately create the lien? No. The court-review and show-cause steps in § 9-106(a)(1) come first.
Can a subcontractor claim the whole unpaid subcontract price against the owner's new home? Only up to the amount the owner still owed the contractor when the § 9-104 notice arrived, and not at all if the owner had already paid the contractor in full (§ 9-104(a)(2), (f)(3)).
