The City Is Forcing Me to Tear Down My Duplex

TLDR

A fully rented duplex got condemned for structural damage from water intrusion. The city wanted every wall opened up, which would trigger grandfathering rules and force a tear down. I brought in a structural engineer, fought back, and kept the building standing. Nobody is coming to save you. You have to see around the corner yourself.

The Condemnation Notice

This property was fully rented and the city condemned it. In 15 years as a real estate investor and now over 150 rental units owned, I had never needed legal involved to protect my property like this.

The condemnation came with no advance warning. Notice in the mail saying the property has structural damage and is not livable. Which is funny because it was livable. People were living in it.

I am not a slumlord. Safety and liability has to be covered on every property. Structural issues absolutely fall under that. But the city had not seen the inside of the house. They had seen the outside. The outside of this duplex is in good shape. It is a B-class to high C-class property. No visible signs of structural damage from the curb.

The real issue was water. This property sits at the low spot in the neighborhood. Every big rain, water pours toward the house, partly because the city storm water drainage was backing up out of the manhole in the middle of the street. Water was getting under the building and the floor system was sinking.

The city was right that there was a water problem. They were wrong about how to fix it.

The Three Structural Fixes in Order

Before legal got involved, I went to the city and asked what they wanted done. They asked for an engineer letter. That is where I want to pause and lay out how structural work actually sequences.

Grading is always first. Water is the enemy. If the yard slopes toward the house, you are fighting physics. Regrade the ground so water flows away from the foundation.

On this duplex, we had to bring in a lot of dirt to raise the ground around the house so water would flow off the roof and away instead of pooling. That worked until it created a new problem. The new dirt was higher than the crawl space vents, which meant air could not circulate under the house. Moisture buildup and mold risk.

So we cut in power vents with fans to keep air moving. Then we opened the floors, pulled up pieces of the plywood subfloor, and brought in crews to do the work by hand because machinery could not fit. Under the floor we graded the ground, laid plastic, poured in gravel, and installed sump pumps that routed water to the back of the house where the storm drainage was supposed to carry it away.

That was step one. Stop the bleeding. Engineer signed off. Then the city moved to step two.

Common Mistake

Fixing the structure before you fix the water. You will re-fix everything in a year. Always stop the bleeding first.

The Drywall Trap

This is where it got dangerous. The city said the only way to assess the structure was to take off all of the drywall.

On the surface, that sounds reasonable. Open the walls so they can see the framing, electrical, plumbing.

Here is what actually happens when you open those walls. Everything inside is now subject to current code. That is grandfathering. When a property was built to the code of its era, you can leave it alone as long as you are not touching it. The second you open the walls, you trigger upgrades.

The city email also included a line that said if the renovation exceeds 50% of the building’s value, the property has to be torn down. That is a standard substantial improvement rule. Then I asked what value they assigned the duplex. $80,000.

So if I spent $40,000 on this renovation, I had to tear it down. Legally. Two bathrooms and some floors is $40,000 in a lot of markets. The math said I was being walked into a tear down.

This was the moment legal got involved. I know the drywall rule. Somebody who did not know that grandfathering works this way could have torn the drywall off and been boxed into a corner with no path out.

Never take drywall off a condemned property on the city’s request without an attorney reviewing the grandfathering and substantial improvement rules first. That single action can force you into a tear down you cannot stop.

The Engineer Is Your Shield

When you are in a structural fight with the city, your best ally is a licensed structural engineer. Their letter is the document the city has to respect.

After the drywall fight, we agreed the structural engineer would drive the work. They came in, looked at the floor system, and specified a beam across the center of the crawl space plus sister joists where needed. Around $10,000 of work.

Crews did the work. The engineer wrote a letter saying it was complete and the structure met spec. That letter is the shield.

The engineer is not there to read the code book at you. If that is what you wanted, you could do it yourself. A good engineer thinks outside the code book and designs a plan that is within reason, meets safety, and does not force you to rebuild the house. That negotiation, with the engineer first and the city second, is where you actually win these fights.

The final battle was the city pushing back on unlevel floors after the beam went in. Unlevel floors are cosmetic. The engineer said the structure is sound. The letter is on file. That is the fight I am finishing right now.

A structural engineer’s letter is the only piece of paper the city cannot ignore.

You Are Not the Damsel

Here is the thing I need you to take from this. You are not the damsel in distress. Nobody is coming to save you except you.

You have to get educated. You have to gain the skills. Knowledge times experience equals skill. Reading about code without ever fighting the city does not make you skilled. Fighting the city without reading the rules does not either. You need both.

In this case, seeing around the corner on the drywall request is what saved the building. The city is not evil. The engineer is not magic. The attorney is not a miracle worker. None of them are replacing the fact that you have to see the trap before it closes.

Every city runs on rules. The rules have levers. The levers have consequences. If you do not know what happens when you pull a lever, somebody else is going to pull it for you.

Pro Tip

Before you pull off drywall, rip out a furnace, or open a wall on a condemned property, ask a local investor or attorney what that triggers under your city’s code. Five minutes of asking beats $200,000 in forced tear down.

FAQ

What is grandfathering in the context of building code?

When a property was built to the code of its time, you can leave the non-conforming items in place as long as you are not renovating. Once you renovate the affected system, you have to bring it up to current code. It is the reason old houses still have 2x4 walls with R13 insulation instead of the current higher R values.

When should I get an attorney involved with the city?

When the city is asking for something that could force a tear down or cost six figures. Minor inspection failures and typical permit back and forth do not need an attorney. Structural threats and condemnation always do.

Can the city really force me to tear down a rental?

In some scenarios yes. The substantial improvement rule, which caps renovation cost at a percentage of building value, is common. If your renovation exceeds that percentage, the property has to be brought fully up to code, which often means tear down and rebuild. Know your municipality’s threshold before you start work.

I am just starting. How do I learn this stuff before I need it?

Go to your city’s planning and codes office and ask for a copy of the local code. Read the sections on rental housing, substantial improvement, and grandfathering. Attend a local real estate meetup and ask who has fought the city recently. Learning this in advance is free. Learning it in the middle of a condemnation is expensive.

Why did the water flow toward the house in the first place?

Grading. The yard sloped toward the foundation and the storm drainage in the street was not handling the volume. Both problems together meant every heavy rain, water pooled at the low spot, which happened to be this duplex.
