What happens if you buy a house with unpermitted additions?
When buying a home, it is important to review what recent work has been completed and the proper permits have been pulled. These permits will ensure the work was properly completed and a city inspector verified the work. This generally occurs during the home inspection process and a good home inspector will include pulling recent permits.
When purchasing a property, you will also inherent 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. The city inspector will want to open the walls to ensure that the plumbing or electrical are completed to meet building codes.
Homeowners insurance Policies
Homeowners insurance policies may also not insure any unpermitted work. It is reasonable for an insurance company to question any unpermitted electrical work that could cause a fire increasing the risk on the home. It would be worth verifying any of these tasks 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
Although there are risks, accepting unpermitted construction can sometimes get you 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 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.
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.

This may have you sell the house "as-is" which will need a steep discount for many buyers to take on the additional risk and liability.

Does finishing a basement increase property taxes?
