Let's talk about one of the most common questions I get from buyers:
"Wait... was that done legally?"
In both the San Francisco Bay Area and Nevada County, it's incredibly common to find homes with some amount of unpermitted work.
Maybe a garage was converted into living space.
Maybe a bathroom was added.
Maybe a deck was built.
Maybe someone finished a basement to create a rental unit that's bringing in $2,000 a month.
Maybe the previous owner replaced a water heater, moved some walls, or finished off an attic.
The moment buyers hear the phrase "unpermitted work," anxiety tends to follow.
So let's break down what it actually means, what the risks are, and how to approach it without panicking.
First, the disclaimer:
I'm a Realtor, not a building inspector, contractor, attorney, or permit official. Permit requirements vary by city and county, and if you have specific questions about a property, you should always consult the appropriate professionals.
Why Do People Do Work Without Permits?
Most homeowners aren't sitting around plotting building code violations.
Usually it comes down to one of four things.
Cost
Permitted work costs more.
There are permit fees, inspections, engineering requirements, and sometimes additional expenses that come from bringing older systems up to current code.
Skipping permits can save money in the short term.
Time
Permitting takes time.
Depending on the project and jurisdiction, permits can add weeks or months to a project timeline.
Some homeowners decide they'd rather move forward than wait.
Lack of Awareness
Many people genuinely don't know when permits are required.
I've had countless conversations with homeowners who were shocked to learn that something they considered a simple replacement or upgrade required permits.
Independence
And yes, some people simply don't want government involvement in their projects.
Whether that's wise is a different conversation.
Does Unpermitted Work Mean Bad Work?
Not necessarily.
This is one of the biggest misconceptions buyers have.
A permit adds oversight.
It does not automatically determine quality.
I've seen beautifully executed projects completed by skilled and licensed professionals that lacked permits.
I've also seen permitted work that wasn't particularly impressive.
The real question isn't:
"Was it permitted?"
The real question is:
"Was it done correctly and safely?"
That's where inspectors, contractors, and specialists come in.
What Are the Risks?
This is where things become important.
When you buy a property, you inherit the property as it exists.
If an issue related to unpermitted work surfaces after closing, you're now the owner dealing with it.
Potential consequences can include:
- Required corrections
- Permit fees
- Fines
- Additional inspections
- Insurance complications
- In rare cases, removal of the unpermitted work
The severity varies tremendously depending on the situation.
Some issues are relatively easy to resolve.
Others can become expensive.
Insurance Can Get Complicated
Insurance companies care about risk.
If a claim involves unpermitted work, coverage can become more complicated.
That's why it's worth discussing any significant unpermitted improvements with your insurance provider before closing.
The last thing you want is a surprise after you've taken ownership.
How Do Violations Usually Get Discovered?
This is another question buyers ask all the time.
The answer is usually much less dramatic than people imagine.
Violations are commonly discovered when:
- A neighbor files a complaint
- An inspector notices something during another permitted project
- The owner applies for permits on a new project
- A safety issue comes to someone's attention
Building departments are generally focused on public safety, not conducting surprise inspections of every house in town.
A Word of Caution for Buyers
Let's say you're under contract on a home.
You suspect the garage conversion wasn't permitted.
Your first instinct might be to call the city and ask:
"Was the garage conversion at 123 Main Street legal?"
Slow down.
Before making calls, talk to your Realtor.
There are ways to gather information and understand permit history without creating unintended complications during a transaction.
A better approach is often to ask general questions about local regulations, request available permit records, and discuss concerns with inspectors and contractors during your investigation period.
Your goal is to gather information, not accidentally create a problem.
So Should You Buy a Home With Unpermitted Work?
Maybe.
Maybe not.
It depends on the work.
It depends on your risk tolerance.
It depends on what your inspections uncover.
And it depends on whether you fully understand what you're buying.
I've had clients happily purchase homes with unpermitted work and never experience a problem.
I've had other clients walk away because the presence of unpermitted work could affect a security clearance, government position, or professional licensing requirements.
Both decisions can be completely reasonable.
My Advice
Don't ignore unpermitted work.
But don't automatically panic, either.
Gather information.
Talk with qualified professionals.
Understand the risks.
And then make an informed decision.
There is no perfect house.
Every property comes with strengths, weaknesses, and quirks.
The goal isn't perfection.
The goal is understanding exactly what you're buying before you move forward.
