How to Sell a House with Unpermitted Work or Additions
Whether it's a finished basement, a converted garage, or a brand-new deck, home improvements are great—unless they were done without the proper city permits. If you are trying to figure out how to sell a house with unpermitted work, you need to know the risks and the best ways to bypass the red tape.
The Dangers of Unpermitted Work During a Sale
When you list a home on the traditional market, unpermitted work will almost always be discovered. Here is how it ruins deals:
- Appraisal Issues: Appraisers will not count unpermitted square footage (like a converted garage) toward the home's value. This can cause the home to under-appraise, killing the buyer's loan.
- City Fines and Tear-Downs: If the city finds out about the unpermitted work, they can issue massive fines or force you to tear the addition down completely.
- Liability: If unpermitted electrical or plumbing work causes a fire or flood after you sell, you could be held legally liable by the new owner.
Your Options for Selling
If you have unpermitted work, you generally have three options:
- Retroactive Permitting: You can apply for "as-built" permits. This often involves tearing open walls so city inspectors can see the wiring and plumbing, paying penalties, and fixing anything that isn't up to code. It is expensive and time-consuming.
- Demolition: You can tear down the unpermitted addition to return the home to its legal state.
- Sell As-Is to a Cash Buyer: The easiest solution is to disclose the unpermitted work and sell the home as-is to an investor like Iron Oaks Property Group. We take on the liability and the hassle of dealing with the city so you can walk away clean.
Frequently Asked Questions (FAQ)
1. Do I have to disclose unpermitted work?
Yes. Failing to disclose known unpermitted work is a form of real estate fraud and leaves you open to severe lawsuits from the buyer.
2. What if the previous owner did the unpermitted work?
Unfortunately, the burden falls on the current owner. Even if you didn't do the work, you are responsible for it when you go to sell.
3. Will a bank finance a house with unpermitted additions?
Usually, no. If the unpermitted work poses a safety hazard or significantly alters the home's footprint, lenders will deny the loan.
4. Do cash buyers care about permits?
We factor the cost of retroactive permitting or fixing the work into our cash offer, but it does not stop us from buying the home.
5. How fast can I sell my house with unpermitted work?
By selling to a cash buyer, you can bypass the city inspectors and close in just a few days.
