What to Do About Unpermitted Work When Buying or Selling a Home

Updated: Nov 26, 2020

What happens if you buy a house with unpermitted additions?

When buying a home, it is important to inspect the work that has been completed. This includes reviewing all recent work and checking if the proper permits have been pulled. These permits will ensure that a city inspector verified the work before the walls were covered up. This generally occurs during the home inspection process and a good home inspector will include pulling recent permits.

City Penalties

When purchasing a property, you will also inherit any risks that come with any unpermitted work from the previous owner. This can include if the city comes after you with fines or even having to open up walls for an inspector. Depending on the work that was completed, you may even be required to hire an architect that can get expensive. Remediation is when the permits are pulled after the work has been completed. The city inspector will want to tear down the walls to ensure that the plumbing or electrical is completed to meet building codes.

Homeowners Insurance Policies

Homeowner's insurance policies may also not insure any unpermitted work. It is reasonable for an insurance company to question any unpermitted electrical work, this work could increase the fire risk of the home. The insurance company has the right to drop your coverage which means that you will either have to remediate the work or find a new company that will offer to increase coverage. It would be worth verifying any questions you have with your insurance company to ensure that you are on the same page

Mortgage Note Called

Many mortgage contracts have a clause that can allow them to call the mortgage note and demand immediate repayment of the entire cost of the loan if unpermitted work is completed. This could degrade the value of the property that they have a lien against and could risk their investment. This is an unlikely but possible scenario.


Many neighbors are very aware of everything that is happening in their neighborhood including any home improvements. Especially if you have a large dumpster outside for a few days it wouldn't be uncommon for a nosy neighbor to call the city for them to investigate farther.

Buyers How to handle unpermitted work

Accepting the offer

There are risks to accepting unpermitted construction, however, you can sometimes get a great deal. If you are able to purchase the property ignoring the value of the unpermitted edition you can score a good deal. From there you may contact the city and go through the process to get the retroactive permits that are needed. If there is some additional work it should be minimal since you as the home buyer have already costed that into your purchase price.

Seller Fixes The Issue

While under contract, you may ask the home seller to solve the problem. This could include them going to the city's building department and ensuring all permits and inspections are complete before the closing. Since many homes sold without permitting are sold "as is" or the seller didn't want to get permits in the first place, it is unlikely they will get the permits during the home sale process.

Move On

If you don't feel comfortable taking on the unpermitted work or if the seller won't cut you a break on the price it can be worth it to move on from the transaction and find a new home. A good real estate agent should warn you about these hurdles and highlight the pros and cons of a transaction. If your agent is pushing you to go through a sale with a multitude of unpermitted work, it might be worth getting a second opinion or finding a new realtor®.
