“There are rats” goes nowhere. “Tall grass, open trash, and the rats they draw” gets an inspector.
A rat in the alley is not a code violation. The tall grass, the pile of tires, and the open trash bags that feed it are. That is why more than half of Columbus rodent complaints arrive at the city as a tall grass or trash complaint, and why a complaint that only says "rats" so often goes nowhere.
Inside an occupied home it is the other way round. An infestation inside is a habitability problem the city acts on directly. This guide covers both, with the words that work.
Is a rat a code violation in Columbus?
Inside an occupied home, yes. Rats or mice inside a dwelling are an infestation, and the city files the complaint as one ("Occupied / Infestation" in its records). In a rental, treating it is the landlord’s job.
Outside, the violation is the harborage, not the animal. The city’s environmental code covers overgrowth, accumulated solid waste, junk, and conditions that harbor or feed rodents. An inspector can cite those. An inspector cannot cite a rat that ran across a yard.
The city’s own records show how this works. From Jan 2025 through August 2026, Columbus logged 3,608 complaints that mention rats, mice, or rodents. 63% of them also carry a tall grass or trash complaint. The rat was the reason the neighbor finally called about the yard.
Know Your Block has asked the City of Columbus to confirm the exact code sections that cover rodent harborage. This page will quote the answer when it arrives.
Report the harborage, not the rat
Five rules for the complaint itself. Each one hands the inspector something to cite.
Say where the rats are coming from
Not "rats in the neighborhood." The address, or the lot, and the spot on it: under the shed, behind the garage, along the fence line, in the tall grass by the alley. Burrows are the best evidence. Say "burrows" if you see holes in the ground.
Describe what is feeding and sheltering them
Open or overflowing trash, bags left outside the can, a junk pile, tires, lumber, a broken-down car, pet food or bird seed on the ground, chicken feed, dog waste, a vacant lot gone to weeds. Name the condition. That is the citable part.
Say how long
"Since spring." "Every summer for three years." "Since the tenants moved out in June." A timeline turns a sighting into a pattern, and a pattern is what moves a case. In the records, people wait a median of five months before the first report. Do not.
Say what it is doing to you
Rats in your yard, under your porch, in your car’s engine, in your garage. Children or pets in the yard. Harm to a neighbor is what makes the neighbor’s lot the city’s business.
Offer a photo
A picture of the burrow, the trash, or the pile, taken from your side of the line. Say you have it. You do not have to trespass to document a lot next door.
File with Columbus 311, online or by calling 311. The public record shows the complaint and the address, not who filed it, and you can ask that your name be kept off the report.
What to say in the six common situations
| Situation | What to say |
|---|---|
| The neighbor’s yard | "Tall grass and a pile of [junk, tires, lumber] at [address]. Rats are burrowing under it and coming through the fence into our yard. Ongoing since [month]." |
| The alley | "Trash bags left in the alley behind [block] and not taken to the collection point. Rats in the alley every evening, in the cars parked there, and in our yard." |
| A dumpster | "Dumpster at [complex or business] overflows between pickups and bags are left beside it. Rats have burrowed under the bushes next to it." |
| Chickens or animal feed | "Chickens kept at [address] with feed on the ground. It is drawing rats into the yards on both sides." |
| Dog waste | "Dog waste from several dogs not cleaned up at [address] for months. Rats and smell in adjoining yards." |
| A vacant lot or house | "Vacant lot [or house] at [address] gone to weeds with dumped trash. Rats coming from it into occupied homes." File it as a vacant property report too. |
One warning from the records. Vacant houses and homeless camps get blamed in about one rodent complaint in ten, but a rat complaint is no closer to either one than any other complaint. If you name a vacant house, name the condition on it, not the vacancy.
Rats inside your home
Different report, different rule. Say "inside", give the unit, and describe the entry point if you can see it: a gap under a door, a hole behind the stove, a chewed screen. Say when you told the landlord and what they did. In a Columbus rental, treating an infestation inside the unit is the landlord’s job. A report to 311 puts the problem on the public record and starts the clock.
If you have mice rather than rats, and a landlord who hands out traps, read the mice guide. Traps do not close a case. Sealed holes do.
If you told the landlord and nothing happened, your options in Ohio.
Is it anonymous, and what happens to my neighbor?
The public case record shows the complaint and the address, not who filed it. You can ask 311 to keep your name off the report when you file. An inspector visits, and if there is a violation the owner gets a notice with time to fix it. Fines and court come only after the notice is ignored. A report is a request for the city to look, not a punishment.
In the records, 21 rodent complaints ask to stay anonymous and 15 mention fear of retaliation. If that is your situation, say so in the complaint.
See what is already on the record
Before you file, look up the address. If the same lot or block already shows rat, trash, or overgrowth complaints, say so in your report. In the city’s records, 82% of rodent addresses have been reported exactly once, so a second report on the same lot stands out.

Common questions
How do I report rats in Columbus?
Call 311, use the Columbus 311 app, or file at 311.columbus.gov. Give the address and describe the condition that draws the rats: tall grass, piled junk, open trash, animal feed, burrows. If the rats are inside your home, say "inside" and give the unit. The city cites the condition outside and the infestation inside.
Are rats a code violation in Columbus?
Inside an occupied home, an infestation is a habitability violation. Outside, the violation is the condition that harbors or feeds rats, such as overgrowth, accumulated trash, junk, and animal feed, not the animal itself. Report the condition.
Who do I call about rats in my neighbor’s yard?
Columbus 311, at (614) 645-3111 or online. Describe what on the neighbor’s lot is feeding or sheltering the rats and how it reaches your property. The record shows the address, not your name.
Does the city of Columbus do rat control?
Columbus code enforcement acts on the conditions that harbor rats and on infestations inside occupied homes. It does not exterminate rats on private property. That is the owner’s job, and in a rental the landlord’s. A 311 report is what makes the city look.
How long should I wait before reporting rats?
Do not wait. In Columbus complaint records, people who state a duration have lived with the problem for a median of five months before filing, and one in four say a year or more. The record starts when you report.
