If you build in Ohio, the rules that govern your business sit in three places: the state licensing authority, the state lien statute, and the state prevailing-wage law. Cost bands, permit timelines, and common project types layer on top. Get any of these wrong and you bid the wrong number, miss the lien deadline, or lose the certificate of occupancy. Here’s what Ohiocontractors need to know in 2026, plus how BuildCrux fits into your daily workflow.
BuildCrux runs AI estimating, scheduling, change-order management, lien-aware invoicing, mileage tracking, and customer communication in one place. Every screen is built for the field, not the back office. The numbers below come from current state law, published cost references, and 2026 market data. Verify specific project rules with your AHJ before bidding.
Ohio contractor licensing
Ohio Construction Industry Licensing Board (OCILB) for specialty trades; city/county for GCs
No state-level general contractor license. Most major cities (Columbus, Cleveland, Cincinnati) require GC registration. Specialty trades (electrical, plumbing, HVAC, hydronics, refrigeration) state-licensed through OCILB.
- Application + first-year fees
- State specialty: $200-$300 application + bond. City GC registration $50-$300 typical.
- Renewal period
- 1-3 years
Mechanics liens in Ohio
Filing deadline: 60 days after last work for residential projects (1-2 family); 75 days for other projects. Lien is filed with the county recorder. Lawsuit to enforce within 6 years.
Preliminary notice: Ohio requires a Notice of Furnishing from sub-tier claimants on commercial projects within 21 days of first work. Residential 1-2 family projects have different rules.
Lien rights are how you actually get paid when an owner stops paying. Missing the deadline forfeits the security entirely. The mechanics lien is the contractor’s primary security; the preliminary notice is the prerequisite that protects it. Read the lien waiver entry too — that’s the document you’ll exchange for every progress payment.
BuildCrux tracks your last-work date per project and surfaces lien-deadline reminders so the math doesn’t happen on the back of an envelope at month-end.
Prevailing wage in Ohio
Ohio has a state prevailing-wage law for public works projects $250,000 (new) / $75,000 (renovation) and above. The Ohio Department of Commerce publishes wage rates.
For background on how prevailing-wage rules work, see our prevailing wage glossary entry and the Davis-Bacon Act explainer. The federal U.S. Department of Labor wage determinations site publishes prevailing rates on federally funded projects.
