One evening two tenants at one of my rental buildings started arguing in the parking lot over a spot that was not even assigned to either of them, and by the time I got the phone call it had turned into a full shouting match with a car blocked in for over an hour. In 15 years of self-managing 9 properties, I have dealt with 11 separate parking disputes, and they eat up more of my evening phone time than almost any other complaint category except noise. Here is the process I now use to shut a parking fight down fast, usually within 48 hours of the first call.
Why Parking Disputes Escalate So Quickly

Parking feels personal in a way that shared hallways or trash areas do not, because a tenant sees the same car in their spot every single day. On a property with only 12 spaces for 15 units, which is the ratio at two of my buildings, even a single misparked car creates a daily irritation that builds up fast. I have learned that a complaint ignored for more than 3 or 4 days almost always turns into a formal grievance, so speed matters more than being perfectly right on the first call.
Step 1: Get the Facts Before You Referee

I never take one tenant’s account of events as the full picture. I ask both sides to send a short message describing what happened, and I check my own building camera footage when I have it, which covers 6 of my 9 properties now. About 30 percent of the parking complaints I get turn out to involve a visitor’s car or a delivery vehicle rather than another tenant at all, so confirming who actually parked where saves you from accusing the wrong person and losing trust with a good tenant.
Step 2: Check the Lease and Parking Agreement
Every lease I write now includes a parking addendum that names an assigned spot number, because early in my landlord years I rented several units with unassigned open-lot parking and it caused constant friction. If the lease specifies a spot, the fix is simple enforcement. If it does not, which is still true for a handful of my older leases signed more than 10 years ago, I treat the dispute as a policy gap I need to close rather than a fight to referee. Before I respond to either tenant, I run through a short checklist:
- Does the lease name a specific spot number or just parking in general
- Has either tenant received a written warning about parking before
- Is a second or third vehicle involved that was never registered with me
- Does the building have enough spare capacity to solve this without conflict
- Is there camera footage or a witness account to confirm what happened
Step 3: Assign, Label, and Enforce

Once I have the facts, I paint or post the spot number directly on the pavement or a small sign, which costs me about 3,000 yen in materials and half a Saturday afternoon per building. I then send both tenants a short written notice, not a verbal one, confirming who has which spot and the date the assignment takes effect. If a tenant continues parking in another unit’s spot after that notice, my lease allows a 5,000 yen administrative fee for repeat violations, and I have only had to apply that twice in 15 years because the written notice alone resolves almost every case.
Preventing the Next Dispute
The properties where I have never had a parking complaint all share the same setup: individually numbered spots at least 2.5 meters wide, a printed parking map in the entryway, and a line in the welcome packet explaining the policy before move-in day. Retrofitting that system into an older building took me roughly 4 hours of labor and under 10,000 yen in paint and signage, which is far cheaper than the hours I used to lose mediating shouting matches by phone. I also now ask every new tenant to register their vehicle plate at signing, since unregistered second cars are behind a large share of the disputes I still see today.
When Mediation Alone Is Not Enough
Occasionally a tenant refuses to comply even after a written warning and a fee, and in those cases I stop trying to be the peacekeeper and treat it strictly as a lease violation matter, escalating to a formal notice with a clear deadline. Out of my 11 total disputes, only one ever reached that stage, and it resolved once the tenant realized the next step was a lease violation on their record rather than a neighbor argument. Keeping that distinction clear from the start, that this is a contract issue and not a personality conflict, keeps my own stress level down and gets a faster resolution for everyone in the building.
That is the approach I use across all 9 of my properties whenever parking tensions flare up, and it turns what used to be a two week headache into something I can usually close out in two days.
