OPINION
The principal dispute in this case is whether a subcontractor gave proper notice of a payment-bond claim under Minn. Stat. § 574.31, subd. 2(a) (2012). Appellant Safety Signs, LLC, was a subcontractor on a public project. Safety Signs brought suit against general contractor Niles-Wiese Construction Company and respondent-surety Westfield Insurance Company, seeking to recover money owed under the subcontract. It is undisputed that Niles-Wiese defaulted. But Westfield moved for summary judgment on the payment-bond claim because Safety Signs mailed its pre-suit notice of claim to Niles-Wiese at the address listed on the subcontract rather than the address listed on the payment bond. The district court denied the motion and later entered judgment against Westfield. The court of appeals reversed, and we granted Safety Signs’s petition for review. We conclude that Minn.Stat. § 574.31, subd. 2(a), requires a claimant to serve notice оn the contractor at its address as stated in the bond as a prerequisite to filing suit. Because Safety Signs did not comply with the statutory notice requirements, we affirm.
In 2008, Niles-Wiese entered into a contract with the City of Owatonna to build a runway and taxiway at the City’s airport (the Project) and entered into a subcontract with Safety Signs to provide traffic-control services and pavement-marking work for the Project. The subcontract listed Niles-Wiese’s address as “112 South Main Street, P.O. Box 419, Medford, MN 55049.” Westfield provided a payment bond for the Project, under which West-field agreed to be liable in the event that Niles-Wiese failed to pay material suppliers or subcontractors. The payment bond listed Niles-Wiese’s address as “215 NE First Street, Medford, MN 55049.”
Safety Signs’s work on the Project was divided into two phases. On November 7, 2008, Safety Signs completed its work on the first phase of the Project. The company submitted invoices to Niles-Wiesе, but Niles-Wiese did not pay the full amount owed. Consequently, Safety Signs served notice of a bond claim on both Niles-Wiese and Westfield on February 13, 2009. The notice was sent by certified mail to West-field’s address as listed in the payment bond. But Safety Signs’s notice to Niles-Wiese was sent to the address listed in the subcontract (112 South Main Street) rather than the address listed in the bond (215 NE First Street). Safety Signs received
In September 2009, Safety Signs completed its work on the second phase of the Project. The City paid Niles-Wiese and Westfield for the work, but Niles-Wiese once again failed to pay Safety Signs in full. As a result, Safety Signs sent notice of a bond claim by certified mail to both Westfield and Niles-Wiese on January 7, 2010. As with the first bond claim, Safety Signs sent notice to Westfield at the address listed on the bond but sent notice to Niles-Wiese at the address listed on the subcontract, rather than the bond.
The certified letter to Niles-Wiese was returned to Safety Signs marked “Return to Sender — Unclaimed—Unable to Forward.” Westfield, however, responded to the notice and requested that Safety Signs submit proof of its claim. Westfiеld indicated that it would then “solicit [Niles-Wiese’s] position regarding your claim” and advise Safety Signs of its intentions. The letter also contained a reservation of rights, stating that Westfield reserved any defenses it might have to the claim, including “failure to comply with notice or time for suit requirements.” After Safety Signs submitted proof of its claim, Westfield sent a letter notifying Safety Signs that Niles-Wiese had disputed the claim and West-field was therefore denying payment. Westfield copied Gary Wiese of Niles-Wiese on the letter using the address “PO Box 419, Medford, MN 55049-9467.”
On September 8, 2010, Safety Signs served a complaint asserting its payment-bond claim against Westfield and alleging breach of contract, unjust enrichment, and other claims against Niles-Wiese. Niles-Wiese did not answer the complaint, and the district court entered a default judgment against Niles-Wiese. Westfield, however, answered the complaint and moved for summary judgment, arguing that Safety Signs did not send the notiсe to Niles-Wiese at the proper address. In response, Safety Signs submitted evidence that the address to which notice was sent was the address Niles-Wiese listed on its website and the address used on invoices and correspondence between Niles-Wiese and Safety Signs. The district court denied Westfield’s motion and instead issued an order granting summary judgment to Safety Signs on the notice issue. Safety Signs subsequently moved for summary judgment on liability and damages, which the district court granted.
Westfield appealed and advanced several arguments, including that because Safety Signs failed to serve Niles-Wiese at the address listed on the bond, the district court should have granted summary judgment to Westfield. The court of appeals agreed with Westfield’s argument and reversed, concluding that Safety Signs’s notice was fatally defective because it was not sent to Niles-Wiese’s address as listed in the bond.

Safety Signs argues that the court of aрpeals erred because our case law requires only substantial compliance, rather than strict compliance, with the notice requirement. Westfield counters that the plain language of the statute leaves no room for interpretation and expressly requires service at the address listed in the bond as a condition precedent to filing suit. We review de novo a district court’s denial

The Public Contractors’ Performance and Payment Bond Act, codified at Minn. Stat. §§ 574.26-.32 (2012), generally requires cohtractors on public projects to supply payment bonds to ensure the payment “of all just claims” by persons furnishing labor and materials on the project. Minn.Stat. § 574.26, subd. 2. The insurer providing a payment bond is known as a surety and agrees to be liable to “cover any amounts that, because of the general contractor’s default, are not paid to a subcontractor or materials supplier.” Black’s Law Dictionary 201 (9th ed.2009); accord Cretex Cos. v. Constr. Leaders, Inc.,
If a subcontractor is not paid for its work on a public project, it may make a claim against the payment bond. But in order to bring a civil action asserting a payment-bond claim, Minn.Stat. § 574.31 requires the subcontractor to give notice to both the surety and the general contractor before a lawsuit is commenced. In particular, the statute provides,
In the event of a claim on a payment bond by a person furnishing labor and materials, no action shall be maintained on the payment bond unless, within 120 days after completion, delivery, or provision by the person of its last item of labor and materials, for the public work, the person serves written notice of claim under the payment bond personally or by certified mail upon the surеty that issued the bond and the contractor on whose behalf the bond was issued at their addresses as stated in the bond specifying the nature and amount of the claim and the date the claimant furnished its last item of labor and materials for the public work.... For the purpose of this section, notice is sufficient if served personally or via certified mail to the addresses of the contractor and surety listed on the bond.
MinmStat. § 574.31, subd. 2(a).

The principal question before us is whеther a claimant must strictly comply with the statutory directive to serve notice on the surety and general contractor “at their addresses as stated in the bond,” id. (emphasis added), or whether substantial compliance with the statutory notice requirement is sufficient. In analyzing whether strict compliance with a statute is mandatory, we are guided by the language of the statute. Ruiz v. 1st Fid. Loan Servicing, LLC,
Here, Minn.Stat. § 574.31, subd. 2(a), provides that “no action shall be maintained ... unless ” pre-suit notice is served on the surety and the contractor “at their addresses as stated in the bond.” (Emphasis added.) This language is clear, and that clarity is indistinguishable from the statutory language at issue in Ruiz. By specifying that “no action shall be maintained” unless certain conditions are met, the Legislature has unambiguously conditioned a claimant’s right to bring an action on fulfillment of the statutory prerequisites, including service of notice at the addresses “stated in the bond.” Id. When the Legislature specifies a consequence for. a failure to meet a statutory requirement, we generally deem that requirement to be mandatory. See Sullivan v. Credit River Twp.,
In arguing that it need оnly substantially comply with the notice requirement, Safety Signs relies on other language from section 574.31, subdivision 2(a), which states that “[f]or purposes of this section, notice is sufficient if served personally or via certified mail to the addresses of the contractor and surety listed on the bond.” (Emphasis added.) The operative word is “sufficient,” which usually means “Adequate; of such quality, number, force, or value as is necessary for a given purpose.” Black’s Law Dictionary 1571 (9th ed.2009). Safety Signs argues that inherent in the concept of sufficiency “is the notion that other actions might be sufficient, depending on the circumstances.” Therefore, Safety Signs contends, the only way to give separate meaning to this language is to construe it to mean that service at the bond address — while an adequate means of giving notice — “is not the exclusive procedure one must follow” to give notice of a bond claim.
We disagree. Contrary to the construction advanced by Safеty Signs, we conclude that the “notice is sufficient” language simply means that a certified mailing directed to the bond address shall be deemed adequate to put the surety or contractor on constructive notice of the claim, regardless of whether it puts the recipient on actual notice. The “notice is sufficient” language precludes a surety or contractor from arguing that the certified mailing failed to put it on actual notice of the claim becаuse, for example, the recipient changed addresses; the letter never arrived, was lost, or was discarded; or the letter only reached an employee who was not responsible for responding to the claim. Therefore, like the statute at issue in Ruiz, section 574.31, subdivision 2(a), unambiguously mandates strict compliance with the address requirement as a prerequisite to filing suit on a payment bond.
C.
Our conclusion that the plain language of the statutе mandates strict compliance with the address requirement finds additional support in our case law. Although this is the first time we have construed Minn.Stat. § 574.31 in its current form, we have addressed whether strict compliance was required with respect to a similar
In Ceco Steel Products Corp. v. Tapager, the plaintiffs notified the surety of a contractor’s debt for materials furnished on a public prоject, but they failed to file notice of the claim with the county auditor.
Plaintiffs’ causes of action were given them by virtue of the statute; hence the manner and means of enforcement must likewise be in accordance therewith. Whatever right of action was in the claimant or liability on the part of the surety was conditioned upon the use of the statutory remedy. Divorced from that remedy, the right and the liability are non-existent.
Id. at 371-72,
Safety Signs relies on several cases in which we held that a plaintiff need only substantially comply with certain aspects of the notiсe provision under earlier versions of the statute. See Wheeler Lumber Bridge & Supply Co. v. Seaboard Sur. Co.,
This case, like Mineral Resources and Ceco Steel, involves a claimant’s failure to comply with an explicit and specific statutory directive. See Mineral Res.,

We acknowledge that the address requirement in Minn.Stat. § 574.31, subd. 2(a), as written, creates a trap for the unwary. This trap is exacerbated by the fact that the statute provides a temрlate for claimants to use when giving notice, but that template does not direct claimants, as the statute does, to use a particular address. Rather, the template merely instructs claimants to address their notice as follows:
NOTICE OF CLAIM ON PAYMENT BOND FOR PUBLIC WORK
TO: (Surety that issued payment bond) and (The contractor on whose behalf the bond was issued)
NOTICE IS HEREBY GIVEN that the undersigned claimant has a claim against the above-named surety for labor and materials furnished by the undersigned for the public work....
Minn.Stat. § 574.31, subd. 2(a). Claimants might unwittingly rely solely on forms modeled after the statutory template and remain unaware that, to comply with the statute, they must serve notice at the address listed in the bond. Indeed, such claimants may not be represented by counsel when they give notice of a bond claim, and they may lack the ability to research and identify the governing statute. The risk is particularly acute in cases, like this one, when the contractor or surety uses multiple addresses or represents to the public an address other than the address stated in the bond.
Although meritorious claims may sometimes be lost based on a statutory requirement of which the subcontractor is ignorant, this circumstance is not enough to overcome the statute’s plain and unambiguous language. See Minn.Stat. § 645.16(6) (2012) (stating that we may consider “the consequences of a particular interpretation” only if the statutory language is ambiguous). Because the languаge of Minn. Stat. § 574.31, subd. 2(a), leaves no room for construction, Ceco Steel,

Safety Signs contends that West-field waived or modified the requirement to serve notice at the bond address by failing to raise the defect until after the lawsuit was filed and by acquiescing in the use of another address during Safеty Signs’s first claim on the bond. Westfield counters with two arguments: first, that our case law prohibits a surety from ever waiving the provisions of the notice re
We need not resolve the unsettled question of whether the requirements of Minn. Stat. § 574.31, subd. 2(a), may ever be waived. Compare Mineral Res.,
Waiver of a statutory right requires two elements: (1) knowledge of the right, and (2) the intent to waive the right. Frandsen v. Ford Motor Co.,
Safety Signs has failed to meet its burden here. Safety Signs relies on West-field’s failure to object to its first notice of bond claim, which also was sent to the wrong address, and its failure to object to the second notice until after the lawsuit was filed. Although Westfield responded to both of Safety Signs’s notices, its responsive letters contained a complete reservation of its rights to assert any defense to the claim, including “failure to comрly with notice or time for suit requirements.” Nothing in these letters demonstrates that Westfield intended to surrender objections to deficiencies in the notice. See Ceco Steel,
Safety Signs’s other evidence of waiver also is insufficient. Although Safety Signs relies on the fact that Westfield copied Niles-Wiese on its response to Safety Signs’s bond claim using an address similar to the one listed in the subcontract (P.O. Box 419), that fact does not establish that Westfield intended to waive any objections it had under the statute. Likewise, Safety Signs observes that Niles-Wiese used the 112 South Main Street address on its website and on correspondence between Niles-Wiese and Safety Signs. But those facts are not germane to an analysis of whether Westfield demonstrated the intent to waive its objections. When we have found waiver, we have
III.
Safety Signs also argues that Westfield has no standing to contest the adequacy of the notice to Niles-Wiese when it is undisputed that Westfield was properly served. We disagree. In Ceco Steel, we allowed a surety to object to the faсt that another entity (in that case, the county auditor) did not receive the proper notice required by the statute, even though it was undisputed that the surety was notified of the claim. See Ceco Steel,
Because the undisputed evidence establishes that Safety Signs failed to serve notice of its bond claim on Niles-Wiese at its address as stated in the bond and Westfield did not waive its objection to that deficiency, the court of appeals’ decision reversing the judgment in favor of Safety Signs is legally sound.
Affirmed.
Notes
. The general contractor is responsible for ensuring that the payment bond lists — for both the contractor and the surety — addresses "at which the compаnies are authorized to accept service of the notice of the claim.” Minn.Stat. § 574.31, subd. 2(a); see also Minn.Stat. § 574.28. If the contractor fails to provide these addresses "then a claimant under the bond need not provide either the surety or the contractor written notice of its claim under paragraph (a).” Minn.Stat. § 574.31, subd. 2(b).
. Our holding that Minn.Stat. § 574.31, subd. 2(a), mandates strict compliance with the address requirement does not divest district courts of subject matter jurisdiction when the party filing suit оn a payment bond has failed to comply with the requirement. See In re Civil Commitment of Giem,
. Safety Signs's claim that Westfield "modified” the address in the bond through its conduct is at its essence a restatement of its waiver claim and fails for the same reasons.
