Free5 Things Every Marion Homeowner Should Verify
Most contractor problems are preventable. These checks take under an hour and catch the most common hiring mistakes.
Ask for their OH contractor license number, then verify it yourself at the state licensing website before signing anything.
Request a certificate of insurance. Call the carrier directly to confirm general liability and workers' comp are active.
Get at least three written bids. Any quote more than 30% below average is a red flag, not a deal.
Ask specifically about permit requirements for home addition. A contractor who says "no permit needed" for structural work is a liability.
Read recent Google and BBB reviews for complaint patterns, not just star averages. One-star reviews reveal how disputes get resolved.
AboveBoardPros gives you a head start on checks 1 and 2.
In the states our automated check reaches, we cross-check the business against the state registry, and we read the certificate of insurance where a contractor provides one. You still confirm the trade license with your state and ask for a current certificate before you sign.

Home Addition in Marion: Frequently Asked Questions
How much does home addition cost in Marion?
In Marion, home addition typically ranges from $40,000 to $150,000. Getting three written bids from licensed contractors is the most reliable way to calibrate your specific project.
How long does home addition typically take?
Timeline depends on project scope. Ask for a written schedule before work begins, and specifically ask about material lead times and permit inspection windows: these cause most delays.
Do I need a permit for home addition in Marion?
Home additions always require a building permit. The permit process covers structural plans, foundation, framing, electrical, and final inspections at multiple stages. No licensed contractor will begin an addition without pulling permits, and unpermitted additions must be disclosed in any home sale.
Are home addition contractors in Marion required to be licensed?
Yes. Marion enforces active licensure and insurance. Ask any contractor for their license number and verify it at the OH state licensing website before signing a contract.
How do I verify a Home Addition contractor's license in Ohio?
In Ohio, contractor licensing is tracked by the Ohio Construction Industry Licensing Board (eLicense Ohio). You can look up any contractor's license status directly at https://elicense4.com.ohio.gov/lookup/licenselookup.aspx. To file a complaint or check for consumer alerts, use the Ohio Attorney General's consumer complaint page at https://www.ohioattorneygeneral.gov/individuals-and-families/consumers/file-a-complaint. Where our automated check reaches a state, we cross-check the business registry for the pros we list, and every listing shows what that check found.
How does AboveBoardPros select home addition contractors?
For the pros we list, we cross-check the official state business registry where our automated check reaches, scan the contractor's own website for credential claims, and pull public business signals.
