What Happens If You Skip Permits?
Failed home inspection at resale
A buyer's inspector will typically identify unpermitted electrical or plumbing work. This can cause a sale to fall through or require expensive remediation before closing.
Homeowner insurance may deny claims
If a water leak or electrical fire occurs in an area where unpermitted work was done, your insurer may deny the claim on the grounds that unpermitted work contributed to the damage.
Code violation notices
In California especially, if a neighbor or city inspector identifies unpermitted work, a violation notice can be issued. Fines and mandatory remediation can exceed the original permit cost many times over.
No inspection = no safety check
The inspection process exists to catch potentially dangerous wiring or plumbing mistakes before they become problems. An uninspected 20-amp circuit wired incorrectly is a fire risk.
How the Permit Process Works
Who pulls the permit
The licensed contractor doing the work - the plumber for plumbing permits, the electrician for electrical permits. You do not pull permits yourself for trade work in most jurisdictions.
Typical cost
$25-100 for most jurisdictions, $100-300 in NYC/SF/major metros. Usually included in the contractor's quote if they do it.
Permit timeline
Same-day to 2 weeks depending on the city. Most suburban cities process residential permits in 1-3 business days. NYC can take longer.
What inspection involves
An inspector visits to check the new circuit or plumbing connection before walls are closed. Takes 15-30 minutes. The contractor coordinates the inspection schedule.

FAQ
Do you need a permit to install a dishwasher?
For a like-for-like replacement using existing hookups: usually no permit needed. For a new dedicated electrical circuit: almost always yes - an electrical permit is required. For new plumbing connections from scratch: yes, plumbing permit required in most US jurisdictions. Permits are pulled by the licensed contractor doing the work (plumber or electrician), not by you.
What happens if you install a dishwasher without a permit?
Three main risks: (1) Failed home inspection at resale - a buyer's inspector will flag unpermitted electrical or plumbing work; (2) Homeowner insurance may deny claims related to water or electrical damage where unpermitted work was done; (3) Code violation notices in strict jurisdictions like California can result in fines. The risk is highest for electrical work - an uninspected circuit is a potential fire hazard and a liability issue.
Who pulls the permit for dishwasher installation?
The licensed contractor doing the work pulls the permit - the plumber for plumbing permits, the electrician for electrical permits. Most licensed contractors include permit pulling in their standard process and quote. Always confirm this before booking. Never hire a contractor who says permits are not necessary for new circuit or new plumbing work - that is a red flag.
