Waterproofing permits in Columbus
Some waterproofing work needs a permit and some doesn't. Here is how it usually breaks down around Columbus, and who decides.
Who issues permits
| Where the house is | Office |
|---|---|
| City of Columbus | Department of Building and Zoning Services |
| Unincorporated Franklin County | Franklin County building department (614-525-3166) |
| Suburban cities | Each city's own building office, or the county that serves it |
Franklin County works under the Residential Code of Ohio.
What usually needs a permit
- Exterior excavation along the foundation.
- Foundation repair.
- Sump work that connects to plumbing, which also needs a licensed plumber.
What often doesn't
Interior drainage, crack injection from inside and dehumidifier installs frequently don't need a permit. "Frequently" is the honest word: the office for your address makes the call, and we check before starting. Where a permit is needed, we pull it.
Licensing in Ohio
Ohio does not license waterproofing contractors at the state level, so "licensed waterproofer" means nothing here. What you can ask for is proof of insurance and registration where the city requires it. Electrical, plumbing, HVAC and refrigeration work are licensed trades in Ohio, and any part of a job in those trades must be done by a licensed contractor.
Questions to ask any contractor
- Will this job need a permit, and who pulls it?
- Is the permit fee in the price?
- Who does any plumbing or electrical part?
- Can I see your certificate of insurance?
