Most community cat colonies live somewhere their caretaker does not own — behind a restaurant, on an industrial estate, around a storage yard, in an apartment complex.
Doing TNR there without permission is common, understandable, and puts the whole programme at risk. Permission is worth having, and it is more obtainable than most caretakers expect.
Why permission matters
- You cannot be asked to leave halfway through a project.
- Traps left overnight are not removed or reported as suspicious.
- The owner does not respond to complaints by calling for the cats to be removed.
- You can put up shelters and stations without them being cleared away.
- Some grant funders and rescue partners require it.
- It protects you legally if anything goes wrong on the site.
The most common failure mode without permission is not confrontation — it is arriving to find shelters gone and being told to stop, halfway to the sterilisation threshold.
Our explainer on the population maths behind TNR covers why an interrupted project achieves so little.
Work out who to ask
This takes longer than the conversation itself and is worth doing properly.
- Identify the actual owner rather than the occupier — a tenant may not have authority.
- For commercial sites, ask for the site manager or facilities manager.
- For apartment complexes, the property management company rather than an individual resident.
- For public land, the relevant city or county department.
- Property records are usually publicly searchable if you cannot tell.
Approaching the wrong person wastes goodwill. A well-meaning employee who says yes without authority cannot protect you when someone senior objects.
Lead with their problem, not yours
This is the core of it. A property owner does not care about cat welfare in the abstract; they care about complaints, liability, mess and cost.
| Their concern | What TNR actually offers |
|---|---|
| Growing number of cats | Numbers stop rising, then fall |
| Noise complaints | Yowling and fighting stop within weeks |
| Smell | Spraying drops sharply after neutering |
| Kittens appearing | Stops entirely |
| Cost | Nothing — you are funding it |
| Liability | You are on site by permission, not trespassing |
| Rodents | A stable cat presence deters them |
The rodent point lands particularly well with warehouses, restaurants and storage sites, and it is honest. Our guide to whether cats actually control rodents covers what to claim and what not to.

Making the approach
In person or by phone beats a letter. Letters are easy to ignore and easy to say no to.
- Be brief. Two minutes, not a presentation.
- Say what you are already doing — you have been feeding, you have counted the cats.
- Say exactly what you are asking for: access at agreed times, permission to place traps and a shelter.
- State clearly that there is no cost to them.
- Offer to keep the site tidy and to be contactable.
- Leave a card or number and follow up once, politely.
Dress and behave like someone solving a problem rather than someone campaigning. It is a practical proposal, not an appeal.
What to offer in return
Small concessions remove most objections and cost you very little.
- Keep the feeding station tidy and remove food promptly.
- Site everything out of public view and away from entrances.
- Provide a contact number for any problems.
- Agree to remove everything if the site changes use.
- Offer to report anything you notice on the site — caretakers are there at odd hours.
- Send a short update when the colony is sterilised.
That last one matters for the long term. An owner who receives “all fourteen are now done and there will be no more kittens” becomes an ally rather than a tolerator.
Put something in writing
Not a contract — a short email confirming what was agreed.
Cover who you are, what you are permitted to do, where, at what times, that there is no cost, and who to contact. Ask them to reply confirming.
This protects you if the site manager changes, which is the commonest way permission quietly evaporates.
If the answer is no
Do not argue, and do not proceed anyway.
Ask what specifically concerns them, since a no is often about one issue you can address. Ask whether a limited trial would be acceptable. Ask whether you may feed off-site nearby.
If it remains no, respect it. Continuing regardless is trespass, it gives TNR a bad reputation locally, and it usually ends with the cats worse off than before.
You can still sterilise cats that come onto adjacent land you do have permission for, which frequently covers a large proportion of the same colony.
Apartment complexes and HOAs
These need a different approach because decisions are made by committee rather than by one person.
Expect it to be slower, expect to be asked to attend a meeting, and prepare a one-page summary rather than relying on conversation.
Our guide to managing community cats around apartments and businesses covers those settings specifically.
Keep the relationship
Permission is not a one-time transaction. Site managers move on, ownership changes, and new staff arrive who know nothing about the arrangement.
Check in annually, re-confirm with anyone new, and keep the written agreement somewhere you can produce it.
Our guides to colony record keeping and handing over colony care cover documenting permissions so they survive a change of caretaker too.
If permission is refused
It happens, and how you respond determines whether the door stays closed permanently.
Ask what specifically the concern is. Refusals are usually about liability, mess, or an assumption that you are asking to leave cats there rather than to reduce their number.
Offer a smaller version — trapping only, no feeding station, on a date they choose, with everything removed afterwards. A limited yes is a far better starting point than an argued no.
If the answer stays no, do not trap on that property. Trapping without permission is the single fastest way to make an entire neighbourhood hostile to TNR, and it can be trespass.
Work the adjacent properties instead. Colony cats range, and sterilising the cats you can reach still reduces the population on the site you cannot.
Frequently Asked Questions
Do I need permission to do TNR on private property?
Yes, and it protects the project. Without it you can be told to stop halfway through, shelters get cleared away, and you have no standing if someone complains or asks for the cats to be removed.
Who should I approach about a colony on commercial land?
The actual owner or site manager rather than an employee or tenant. A well-meaning staff member who agrees without authority cannot protect the arrangement when someone senior objects.
What should I say to a property owner?
Lead with their problem, not cat welfare. Numbers stop rising, noise and spraying stop within weeks, kittens stop appearing, it costs them nothing, and a stable cat presence deters rodents.
Should I get permission in writing?
Yes — a short email confirming who you are, what you may do, where and when, and that there is no cost. This protects you when the site manager changes, which is how permission usually evaporates.
What if the property owner says no?
Respect it. Ask what specifically concerns them, since a no is often about one addressable issue, and ask about a limited trial. Proceeding anyway is trespass and damages TNR’s local reputation.
How do I approach an apartment complex or HOA?
Expect a committee decision rather than one person. Allow more time, prepare a one-page written summary, and be ready to attend a meeting rather than relying on a conversation.
