When Clients Push Back

Common objections and responses:

"It's too expensive."

"Permits protect your investment. Work done without permits can cause problems when you sell and won't be covered by insurance."

"It takes too long."

"We'll build permit time into the schedule. Unpermitted work can result in stop orders and longer delays."

"My neighbor didn't get one."

"That's a risk they took. We do things properly to protect both of us."

FAQ

Do I need a permit for a bathroom remodel?

If moving plumbing, adding electrical, or making structural changes, yes. If just replacing fixtures in same locations, probably not. Check with your local building department.

How long does it take to get a building permit?

1-3 weeks for typical residential projects. Simpler permits may be same-day. Complex projects can take months. Your jurisdiction's backlog affects timing.

Can a homeowner pull their own permit?

Usually yes for their own residence, but they're then responsible for code compliance and passing inspections. Some work still requires licensed contractors.

What happens if I get caught without a permit?

Stop work order, fines, and requirement to obtain permits after the fact. May need to open walls for inspection. Worst case: tear out and redo the work.

Are permit records public?

Yes. Anyone can typically search permit history for a property. This comes up during real estate transactions and can reveal unpermitted work.

Do permits transfer to new owners?

Open permits may create issues at sale. Closed permits are part of property records. New owners inherit any code violations from unpermitted work.

The Bottom Line

Construction permits:

  1. Required for most significant work — Structural, electrical, plumbing, HVAC
  2. Protect everyone — Client, contractor, future owners
  3. Part of the process — Build time and cost into estimates
  4. Never skip — Consequences outweigh any savings
  5. Build relationships — Work well with inspectors

When in doubt, call the building department. It's always easier to get answers upfront than deal with problems later.
