Licenses & Permits in Ohio

General Business License

Ohio requires most businesses to register for a Vendor's License with the Ohio Department of Taxation if they sell taxable goods or services. Entity registration is handled through the Ohio Secretary of State. Many Ohio municipalities levy their own income taxes (RITA — Regional Income Tax Agency, or CCA — Central Collection Agency) in addition to state taxes, and cities like Columbus, Cleveland, and Cincinnati have their own business licensing requirements. The Ohio Business Gateway portal helps streamline multi-agency registration.

A $500,000 home addition with a 10% fee generates $50,000 gross. Residential projects take 12–18 months from design through construction completion.

Yes — practicing architecture (designing buildings and signing construction documents) legally requires a state architecture license. The ARE (Architect Registration Examination) has 6 divisions. Unlicensed designers can offer limited design services but cannot call themselves architects or seal construction documents.

Revit (BIM) is the industry standard for commercial projects, while AutoCAD remains common for smaller firms. SketchUp is popular for early-concept design. Rendering software (Enscape, Lumion) creates client presentations. ArchiCAD is an alternative full BIM platform with a strong European following.
