How to Buy a Home With an Unpermitted Addition Safely
Unpermitted additions are common in Los Angeles. A converted garage, an extended bedroom, an added bathroom, work that was done without permits, either because the previous owner didn't want to deal with the city or didn't know they needed to.
Buying a home with unpermitted work isn't necessarily a bad decision. But it requires careful thought and proper due diligence. Here's what you need to know.
Why unpermitted work is a problem
The obvious issue is code compliance. If the work wasn't permitted, it wasn't inspected. That means you don't know if it was done safely or to current building standards. Electrical work that doesn't meet code is a fire risk. Structural work that wasn't engineered properly is a safety risk.
The less obvious issue is resale and financing. When you go to sell, many buyers won't touch a property with unpermitted work. Some lenders won't finance homes with significant unpermitted additions.
And if the city discovers the work during a complaint, a remodel, or an inspection, they can require you to bring it up to code, remove it entirely, or pay fines. That becomes your problem, not the previous owner's.
How to evaluate unpermitted work
Not all unpermitted work is equally risky. A bathroom added in 1985 without permits but functioning fine for 40 years is different from a bedroom conversion done last year by an unlicensed contractor.
Ask the seller for any documentation they have about the work. Who did it? When? Are there receipts or contracts? Even without permits, professional contractors generally do better work than DIY projects.
Hire a licensed contractor or structural engineer to evaluate the quality. Can it be brought up to code relatively easily, or is it so poorly done it would need to be completely redone?
Can you permit it after the fact?
Sometimes. Los Angeles has processes for permitting work retroactively, but it's not guaranteed. You'll need to submit plans, pay fees, and potentially bring the work up to current code standards, which can be expensive if the original work doesn't meet modern requirements.
Talk to a permit expediter or contractor before you buy to get a realistic sense of whether retroactive permitting is feasible and what it would cost. Factor that into your offer price.
How much should you discount your offer?
This depends on the scope of the work and the likelihood of problems. A small unpermitted addition that's been in place for decades and appears well-built might warrant a 5 to 10 percent discount to account for future resale difficulty.
A large addition that's clearly DIY and doesn't meet code might warrant a 20 to 30 percent discount, or walking away entirely.
The right approach is to get estimates for what it would cost to either permit the work retroactively or remove it and restore the property to its original state. Then decide whether you're comfortable with that risk.
When to walk away
If the unpermitted work is structural, foundation changes, removed load-bearing walls, second-storey additions, and there's no documentation or engineering to back it up, walking away is usually the right call.
If the seller isn't disclosing the unpermitted work and you discover it during due diligence, that's a serious warning sign about how the rest of the transaction will go.
I've represented buyers who've purchased homes with unpermitted work and been completely fine. I've also seen buyers get stuck with expensive remediation or struggle to resell years later.
The key is going in with your eyes open. Understand the risks, get professional opinions, negotiate the price to reflect those risks, and make sure you're comfortable with the worst-case scenario before you commit.
