South Dakota mechanics lien law and deadlines
In South Dakota, a lien statement must be filed with the county register of deeds within 120 days after your last work or materials, after mailing a copy to the owner. You have up to six years to enforce it, unless the owner demands suit sooner.
South Dakota's mechanics lien law is SDCL Chapter 44-9, Mechanics' and Materialmen's Liens. The lien ends 120 days after you did the last work or furnished the last item unless a verified lien statement is filed with the register of deeds of the county where the property is (SDCL 44-9-15). Before filing, you mail a copy to the owner by registered or certified mail and attach the post office receipt (44-9-17). Enforcement is unusually long: up to six years from the last item in your lien statement (44-9-24). But the owner can cut that to 30 days with a written demand to sue (44-9-26).

| Owner's demand to sue | Start suit within 30 days after the owner serves a written demand, or the lien is forfeited | 44-9-26 |
| Public projects | No lien; contractor furnishes surety of at least the contract price covering payment of labor and material | 5-21-1 |
Who has lien rights in South Dakota
SDCL 44-9-1 is broad. Anyone who furnishes skill, labor, services, equipment, or materials for the improvement of property, at the request of the owner, the owner's agent, or any contractor or subcontractor, has a lien. That wording covers general contractors, subs at any tier, suppliers, and equipment providers. "Skill" and "services" are named, which gives design and professional services a statutory hook, though a design firm should confirm with counsel. Covered work includes building, altering, repairing, or removing structures, plus grading, excavating, ditches, wells, sidewalks, curbs, paving, sewer, and conduit, including in the adjoining half of the street.
Against the owner, the lien attaches from the time the claimant furnishes its first item of material or labor on the premises (44-9-7). If you contracted with the owner at an agreed price, your lien is for that price plus agreed extras. Everyone else, and anyone claiming against parties other than the owner, gets the reasonable value of what was furnished (44-9-6).
Preliminary notices in South Dakota
South Dakota does not require a preliminary notice on every job. A notice requirement kicks in only when the owner or direct contractor opts into the commencement system. Under 44-9-50 and 44-9-51, either may file a notice of project commencement with the register of deeds within 30 days of starting work and post the contractor's name, address, and a location notice at the site. When that has happened, 44-9-53 says a sub-subcontractor or a supplier to a subcontractor cannot extend its lien unless it first mails a notice of furnishing to the contractor named in the commencement notice by certified or registered mail, with a copy to the owner of record, no later than 60 days after its last work.
- Contents: your name, who hired you, a description and price of what you furnished (with specially fabricated materials stated separately), the project, first and last dates, and the amount claimed.
- Proof: the post office receipt for the notice gets attached to the lien statement when you file.
- Exemption: individual laborers with liens under $2,000 do not need it.
- Optional owner notice for anyone: under 44-9-10 you may serve the owner a sworn account at any time. The owner must then withhold enough from the contractor to cover it, and if the contractor does not dispute it in writing within 15 days, the owner may pay you directly (44-9-11).
Filing the lien statement
The statement goes to the register of deeds in the county where the property is located (for railway and utility lines, the secretary of state). Under 44-9-16 it must be verified by someone with knowledge of the facts and state the intent to claim a lien and the amount, that the amount is due, the names and addresses of the claimant and the party you worked for, the dates of your first and last items, a property description, the owner's name and address, and an itemized account. The register of deeds charges the filing fee set in 7-9-15(3); satisfaction filings are free (44-9-19).
Enforcing the lien
The lien is enforced by an action in circuit court in the county where the property is, run like a mortgage foreclosure (44-9-23). The plaintiff files a notice of pendency with the register of deeds, and other lien claimants then have to join that case (44-9-28). The six-year outer limit in 44-9-24 is generous, but owners know about 44-9-26: a written demand to commence suit gives you 30 days, after which the lien is forfeited and can be cancelled of record. An owner can also demand an itemized, verified account within 15 days after completion of the contract, and no enforcement action may start until 10 days after you provide it (44-9-14).
Homesteads and residential work
This is the biggest South Dakota difference. Under 44-9-5, a mechanics lien does not extend to or affect the homestead right, to the extent the homestead is exempt from levy and sale on execution. In practice, that can sharply limit a lien on an owner-occupied home, so residential contractors should secure payment through draw schedules and deposits rather than counting on the lien. Section 44-9-2 also says a landlord's interest is not subject to a lien for repairs ordered by the tenant.
Lien waivers and releases
Chapter 44-9 does not prescribe a statutory lien waiver form, so waiver terms come from your contracts. It does regulate releases after payment. Once a filed lien is satisfied, the claimant must deliver a satisfaction to the owner, witnessed or notarized, for filing with the register of deeds (44-9-21). Failing to deliver it within 10 days after a written demand makes the lien holder liable for damages, costs, attorney fees, and an extra $100 penalty (44-9-22).
Public projects use payment bonds
You cannot lien public property. Under SDCL 5-21-1, a contractor on a public improvement must furnish surety of at least the contract price, with an added obligation to promptly pay everyone supplying labor or material. That is South Dakota's payment bond rule. If the public body does not sue on the bond within six months after completion and final settlement, an unpaid supplier can sue in its name, but not until six months after completion and final settlement and no later than one year after that (5-21-6).

Frequently asked questions
How long do I have to file a mechanics lien in South Dakota?
One hundred twenty days after you did the last work or furnished the last item. File a verified lien statement with the register of deeds in the county where the property is, after mailing a copy to the owner by registered or certified mail (SDCL 44-9-15, 44-9-17).
Does South Dakota require a preliminary notice?
Only in one case. If the owner or direct contractor filed and posted a notice of project commencement, sub-subcontractors and suppliers to subcontractors must mail a notice of furnishing to the contractor, with a copy to the owner, within 60 days after their last work (44-9-53).
How long does a South Dakota mechanics lien last?
Up to six years from the last item in the lien statement (44-9-24). But if the owner, the owner's agent, or the contractor serves a written demand to sue, you have 30 days to start suit or the lien is forfeited (44-9-26).
Can I put a mechanics lien on a house in South Dakota?
You can file one, but under 44-9-5 the lien does not affect the owner's homestead right to the extent the homestead is exempt from execution, which can limit what the lien reaches on an owner-occupied home.
What about public projects in South Dakota?
No lien. The contractor furnishes surety of at least the contract price that covers payment for labor and material (SDCL 5-21-1). Unpaid suppliers can sue on it within the windows in 5-21-6.
