Trade Contractor Registration with Oklahoma County (electrical, mechanical, plumbing): The registration fee is not published on the county's commercial permit form or Planning page; contact the Oklahoma County Planning Department (405-713-1361) for the current amount.

What does a contractor or trade need in Oklahoma County that other businesses do not?

6 of the 6 permits particular to a contractor or trade here apply to no other business type we cover in Oklahoma County: Trade Contractor Registration with Oklahoma County (electrical, mechanical, plumbing), General Contractor Licensing — Construction Industries Board Position (Oklahoma), Electrical Contractor License and 3 more.

Trade Contractor Registration with Oklahoma County (electrical, mechanical, plumbing)

An electrical, mechanical or plumbing contractor working on a permitted project in unincorporated Oklahoma County must register with the county as well as hold the state trade license. The county's current commercial permit form states: "All electrical, mechanical and plumbing contractors must be licensed by the State of Oklahoma. All electrical, mechanical and plumbing contractors must be also registered with Oklahoma County before commencing any work." The predecessor form revised 11-2019 states: "All trade contractors must be registered with Oklahoma County prior to commencing work." The registration fee and form are not published on the county's commercial permit form or Planning page; contact the Oklahoma County Planning Department at 405-713-1361 for the current amount and procedure.

General Contractor Licensing — Construction Industries Board Position (Oklahoma)

The Construction Industries Board's own published FAQ states that 'General Contractors are not currently required to have a state license in Oklahoma,' so there is no state general contractor license fee. The board instead licenses specific trades — electrical, plumbing, mechanical and roofing, each below — and a city or county may still impose its own registration for general building work.

Electrical Contractor License

Three hundred and thirty dollars to become an electrical contractor and $200 a year to stay one, renewing on a personal date tied to the licensee's own birth month rather than a shared calendar date. A journeyman license is far cheaper, $75 to open and $75 to renew, and an apprentice registration is $20 after a $5 application. Renewing late nearly doubles the contractor fee to $300 and raises the journeyman fee to $100. The same fee structure, to the dollar, applies to plumbing and mechanical contracting below.

Mechanical (HVAC) Contractor License

The third of Oklahoma's three uniformly priced trade licenses — $330 to open, $200 a year to renew — covering HVAC and refrigeration work across several sub-categories that differ by scope rather than by fee: limited and unlimited HVAC/refrigeration, limited residential, refrigeration alone, sheet metal, natural gas and process piping. A journeyman is $75 both to open and to renew.

Plumbing Contractor License

The identical structure to electrical licensing — $330 to open, $200 a year to renew, expiring on the licensee's own birth month — reflecting that Oklahoma's Construction Industries Board runs all three of its major trades on one shared fee schedule. A journeyman plumber's license is $75 to open and $75 to renew; an apprentice registers for $20 after a $5 application.

Roofing Contractor Registration

Oklahoma calls this a registration rather than a license, at $75 to register and $75 a year to renew, but a roofer doing commercial work needs a separate endorsement on top — $30 to apply and $200 for the endorsement itself, $230 in total, renewing at $100 a year — required since 2015. A change is coming for residential work too: a new residential roofing endorsement, priced the same way by direct statutory analogy, becomes mandatory on 1 January 2027, having already been pushed back once from an original mid-2026 date, with a year of grandfathering through 1 January 2028 for anyone already registered and in good standing on the trigger date. General liability insurance of $500,000 is required for residential work and $1,000,000 for commercial.

The other 4 local permits in the tables apply to every type of business in Oklahoma County, OK; what each one involves is set out on the Oklahoma County permits page. The 4 state-level registrations apply to every type of business across OK and are covered on the OK state page.
