Buying your first home comes with plenty to worry about, which is why inspections and property records can provide peace of mind before closing. But even after doing your homework, it’s still possible to find something about a house you weren’t expecting.
That’s what happened to one first-time homeowner who learned that a roughly 300-square-foot sunroom included in their home’s living space was apparently an unpermitted addition. By the time they figured it out, they had already closed on the house.
The House Was Listed at 2,300 Square Feet
The home was advertised on the MLS as having 2,300 square feet, including a roughly 300-square-foot sunroom-style addition that opened into the main house.
Nothing about the room initially raised a major red flag. The buyers had the property inspected, and although the inspector pointed out a few things, nothing about the addition was alarming. The homeowner also checked online permit information before closing. The addition wasn’t listed, but because it was older and the records they were viewing showed the same 2,300-square-foot figure as the listing, they assumed the permit simply wasn’t available online.
An Energy-Efficiency Visit Raised Questions
The discovery came almost by accident.
After buying the house, the homeowner had someone come out to discuss energy-efficiency improvements. While looking at the sunroom, the person noticed no insulation under the floor and that the crawl space was too narrow to access. According to the homeowner, the room essentially had wood sitting very close to the dirt below.
That prompted them to review the property records again. They then discovered that the 2,300-square-foot figure they had relied on wasn’t necessarily confirmation from the county that the addition was permitted. According to their account, the records were pulling the square footage from the MLS listing.
They now believe the sunroom was never permitted.
The Condition Underneath the Room Added Another Concern
The permit wasn’t the homeowner’s only worry. Because the crawl space is so tight, they can’t easily inspect much of the underside of the room.
They said part of the floor slopes and that some of the visible wood shows mold. They hadn’t seen obvious signs of severe rot or termites, but limited access made it difficult to know exactly what was happening underneath.
Repairing the structure could mean pulling up the floor from inside the room. But the homeowner worried that once they started opening things up, they could uncover even more problems.
Could the Addition Be Permitted After the Fact?
The homeowner initially considered repairing the wood and adding insulation, but getting the entire room permitted raised a bigger question.
They worried the crawl space might not meet current requirements and wondered whether bringing the addition up to code would require major structural changes. Eventually, they began considering whether it might make more sense to repair what is there for now or someday demolish the addition and rebuild it properly.
However, an unpermitted addition doesn’t automatically mean it has to be torn down.
One person in the discussion who identified themselves as working for a California building department said their department handles a fair number of after-the-fact permits. Depending on the work, that process can require opening walls or other finished areas so inspectors can check electrical, plumbing, and structural components.
What’s required for this house depends on the local building authority, the age of the addition, and how it was built.
The Room May Have Started as Something Else
As the homeowner dug deeper, they began to suspect the addition may originally have been a sunroom or three-season room, possibly built over a patio. At some point, someone may have opened it to the rest of the house and turned it into habitable living space.
The people who sold them the house reportedly didn’t build the addition either, making it difficult to know exactly when the work happened or what the previous owners knew about its permit history.
Whether the room should have been disclosed differently, or whether its square footage was represented correctly, depends on the facts and applicable local laws.
It May Not Be an Emergency
The homeowner’s initial reaction was to imagine the worst: a huge repair bill, extensive code work, or possibly tearing down the room.
But they later clarified that the addition isn’t on the verge of collapsing. Repairing the floor and damaged wood may eventually be necessary, but they began to realize they didn’t necessarily have to solve everything immediately.
That’s perhaps the biggest takeaway from the situation. Discovering unpermitted work after buying a house can raise plenty of questions, but the first step isn’t necessarily tearing everything apart. Understanding the structure’s condition, researching its history, and learning what the local building department would actually require can help you gauge how serious the problem really is.
For this first-time homeowner, what started as a routine visit about energy efficiency ultimately revealed something much bigger: 300 square feet of the house they had just purchased may not have been permitted at all.
