Check for Permits

If you're refinancing, buying or selling a manufactured or mobile home that was altered, a lender may ask you to prove the work was permitted and inspected.

Use the information on this page to check for permits that have been filed for past work, or purchase a Homeowner Requested Inspection to identify unpermitted work. At the inspection, the inspector will let you know what work was done without a permit; and give you a report letting you know what permits you will need to be in compliance.

Did the alternations require a permit?

Check the list of which alterations require permits -- it could save you time and money. The work that was done may not have needed a permit.

Homeowner Requested Inspection

You may be asked by your realtor, lender or appraiser to get a homeowner requested inspection (HRI). Or, you may decide you need an HRI in preparation for the sale or purchase of a manufactured/mobile home. The HRI is designed to identify work that has taken place but did not receive a permit.

In many cases, an HRI is required to satisfy lenders there are no unpermitted alterations.

About buying an homeowner requested inspection

When you buy an HRI, you will need to supply basic site information before making the purchase. An HRI is an inspection only to determine alterations that have taken place without a permit. Any unpermitted work or corrections the inspector finds will require additional permitting.

Important: After purchasing your HRI permit, you will need to request your inspection.

Other ways to buy an homeowner requested inspection

By mail

With My L&I — for contractors

You can track account balances and review your L&I permits and inspection history.

Go to the L&I office nearest you

Request an inspection

After you buy an HRI, and you are ready, you can request the inspection online or in person at a local L&I office.

After you've made the request, your inspector will call you when scheduling inspections in your area. It takes about 10 days for the HRI to take place after you've made the request.

At the inspection, the inspector will let you know if work was done without a permit and give you a report letting you know what permits you will need to be in compliance.

Then, if necessary, you will need to buy the required permits and request the inspections.
