Oklahoma Code, Licensing, and Lien Law

What is tested

Oklahoma code, licensing, and lien law tests state-specific rules: who licenses contractors, which codes apply, and how a contractor preserves payment rights.

Core rules

  • Oklahoma does not issue a single statewide general contractor license. The Construction Industries Board licenses specific trades, and cities such as Oklahoma City and Tulsa require local contractor registration. Verify the local authority having jurisdiction.
  • The Oklahoma Uniform Building Code Commission adopts model codes with state amendments; the current adopted edition controls. Permits and inspections come from the local AHJ.
  • Lien law is in Okla. Stat. tit. 42. A claimant generally files a preliminary notice, often called a pre-lien notice, with the county clerk within 75 days after last furnishing, then a lien statement within 90 days after last furnishing. Foreclosure is generally within one year after the lien statement is filed. Confirm current statutory deadlines for the project type.
  • Lien waivers, notices to owner, and bond claims are contract and statutory tools; keep proof of delivery and dates.

Worked example

Last furnishing is March 1. The 75-day preliminary notice deadline is May 15: 30 days left in March plus 30 in April plus 15 in May. The 90-day lien statement deadline is May 30. If the lien statement is filed May 30, a foreclosure action is generally due within one year, by May 30 of the next year. Reasoning: count calendar days from last furnishing, not from the invoice date; missing the pre-lien can defeat the lien.

Traps

Assuming a state GC license exists; counting from the invoice or contract date; missing the pre-lien notice; filing the lien statement after 90 days; ignoring local registration.
