By trade — does it need a permit?

  • Plumber

    Almost always

    Water heater, sewer line, gas line, repipe, fixture rough-in: permit required. Like-for-like fixture swap (faucet, toilet, disposal): usually no permit.

  • HVAC Technician

    Almost always

    Furnace, AC, ductwork modifications, mini-split install: permit required.

  • Electrician

    Almost always

    Panel upgrade, sub-panel, EV charger, generator hookup, any new circuit: permit required. Outlet/switch replacement: usually no permit.

  • Appliance Repair Tech

    Usually no

    Repairs and like-for-like swaps don't require permits. Hardwired appliances (built-in microwave, garbage disposal new install) may.

  • Gas Technician

    Almost always

    Any gas line work requires permit + Columbia Gas coordination + pressure-test inspection.

  • Concrete Contractor

    Usually no

    Driveway repair, sidewalk replacement, pad pours: usually no permit. New driveway curb-cut, foundation work, or anything in city right-of-way: permit required.

  • Roofer

    Almost always

    Toledo requires a building permit for re-roof + structural roof work. Toledo also requires roofers to register with the city. Skipping the permit voids insurance for any future damage.

  • Tree Service

    Usually no

    Standard tree removal: no permit. Trees in city right-of-way (front-yard tree-lawn): need City of Toledo Forestry approval. Historic-district trees may also need review.

  • Water/Fire/Mold Restoration

    Usually no

    Drywall + insulation removal after water damage: no permit needed. Large-scale mold remediation (>10 sqft): some Ohio cities require permit. Structural repairs after fire damage: yes, permit + Ohio EPA notification if asbestos suspected.

  • Computer & Electronics Repair

    Usually no

    Consumer electronics repair never requires a building permit. Hardwired smart-home installations (whole-home wifi access points, security camera runs through walls) cross into electrician territory and may need an electrical permit if low-voltage cable is run inside finished walls.

Permit offices by jurisdiction

Pick the city or county where the work is happening. Inside city limits = city office. Outside = county office.

Reminders before you sign with a contractor

  • Your contractor pulls the permit, not you. Be wary of any contractor who says "I'll save you the permit fee" — that's the contractor protecting margin, not you.
  • Insurance won't pay if work was unpermitted. Future fire, water, or structural damage from unpermitted work is routinely denied.
  • Permits open the inspection record. Good for you when you sell. Bad for the shady contractor who skipped corners.
  • Plan ahead. Permit issuance can take 1-2 weeks; final inspection 2-4 weeks after work. Add this time to your project timeline.
