GC Laws — Kansas contractor-law checklist preview (free) Sources reviewed 2026-09-30. Public summaries remain free on gclaws.com. [ ] Licensing - The Attorney General states that covered commercial and residential roofing contractors must register before performing roofing work for compensation. Registration is governed by the Roofing Registration Act and its exemptions, including the specified qualifying general-contractor exemption. - The Attorney General’s registration instructions, forms and current registration search provide the applicable roofing process; this is not a general-contractor credential for all construction trades. [ ] Mechanic's liens - A direct contractor ordinarily files the verified statement with the district-court clerk in the property county within four months after last furnishing. On qualifying nonresidential work, filing and serving the statutory notice within that period can extend filing to five months. - A subcontractor or supplier ordinarily has three months after last furnishing. The nonresidential five-month extension requires the statutory notice within the ordinary three months. Section 60-1103 requires service of the claim and preserves the warning and intent-to-perform prerequisites in §§60-1103a and -1103b. - Section 60-1105 generally requires an enforcement action within one year after filing. It has a separate maturity rule for the secured note when a copy of that note is attached as required. [ ] Retainage - The public and private acts ordinarily limit retainage to 5% of the contract or subcontract value. A higher rate, up to 10%, requires a determination that it is needed to ensure performance; subsection (b) separately allows increases for deficient performance. The private act also limits retention from an undisputed payment to 10%. - The public release rule generally requires payment of undisputed retainage within 30 days after substantial completion as part of the regular payment cycle. Retainage attributable to continuing work may be held until 30 days after that work is completed. Fault-based incomplete-work withholding is limited to 150% of its value and paid within 45 days after completion through the regular payment cycle. - The private act requires the owner to release undisputed retainage within 30 days after substantial completion, permitting retention attributable to continuing work until 30 days after completion. Its separate 150% incomplete-work withholding requires fault by the responsible contractor or subcontractor and release within 45 days after that work is completed. [ ] Prompt payment - Covered public owners generally pay a proper undisputed request within 30 days; qualifying extenuating circumstances permit 45 days. An architect or engineer receiving a request must review and forward it within seven business days. Corresponding downstream payments are due within seven business days after receipt when the payment-request conditions are met. - For covered private contracts, the owner pays an undisputed request within 30 days after receipt. Corresponding downstream payments are due within seven business days after receipt, subject to the request conditions. The respective public and private sections specify 18% annual interest for untimely payment. [ ] Prevailing wage - The Kansas Revisor’s chapter 44 index marks §§44-201 through 44-205 repealed. This establishes the status of those former provisions; it does not determine the separate federal or contractual wage terms of an individual project. [ ] Davis-Bacon (federal) - Under 40 U.S.C. section 3142, covered contracts require payment to laborers and mechanics employed directly on the site of the work at least weekly, at rates no lower than the applicable prevailing wage determination. The required compensation includes the basic hourly rate and required fringe benefits, which may be provided through qualifying benefits or cash as the statute permits. - Qualifying apprentices may receive a lower registered-program rate only when the applicable registration and program conditions are met. The Department of Labor’s apprenticeship rules govern those exceptions. - The Department of Labor determines the prevailing rates for the work classifications and locality. Contractors and subcontractors must use the wage determination applicable to their covered contract. - Federal assistance alone does not establish coverage: many, but not all, construction-assistance statutes include Davis-Bacon requirements. Identify the funding program and its governing Related Act. - SAM.gov publishes Davis-Bacon wage determinations. Search by the wage-determination number or the Davis-Bacon public-buildings-or-works category, and match the decision to the contract, locality, and work classification.
