Two years ago a tenant who had rented one of my houses for four years knocked on my door with a proposal: she wanted to start a small home daycare, watching up to 5 children including her own two, out of the 3-bedroom property she was renting from me for 145,000 yen a month. My first reaction was not excitement, it was a mental checklist of everything that could go wrong with insurance, noise complaints, and the terms of my mortgage on that property. After managing 9 rental properties myself for over 15 years, I’ve learned that a request like this needs a calm, structured answer, not a gut reaction, because saying yes too fast or no too fast both cause problems later.
I told her I would look into it and get back to her within a week. That week of homework has basically become a standard process I run every time this topic comes up, and in 15 years of self-managing it has come up 3 separate times, with 2 approvals and 1 refusal so far.
Why This Request Comes Up More Than You Would Think

Home daycare requests are not rare if you own family-sized houses. In many parts of Japan, licensed nursery waitlists still run long, and a small unlicensed in-home setup, sometimes called hoiku mama, fills a real gap for working parents who need care for 2 or 3 kids at a time. Out of my 9 properties, 3 are 3-bedroom or larger houses with yards, which is exactly the kind of property that attracts tenants with young children and, eventually, this exact question. I don’t think of it as an unusual ask anymore, I think of it as something I need a process for.
What I Check in the Lease First

The first thing I pull out is the actual lease contract, not my memory of what it says. Most of my standard leases include a clause restricting the use of the property to residential purposes only. A home daycare, even a small one, technically turns part of the house into a place of business, so on paper it can conflict with that clause. Rather than refuse outright, I treat the clause as the starting point for a negotiation rather than a wall. I’ve amended the lease in writing 3 times over the years to formally permit a home-based daycare business under specific conditions, and each amendment took about 20 minutes to draft once I knew what I wanted to require.
The Zoning and Business License Question
Next I check the zoning designation on the property, which matters more than most tenants expect. Two of my houses sit in a residential zone that allows small-scale home businesses without extra permits as long as fewer than 6 children are cared for at once. One of my other houses is zoned in a way that would require a separate business registration and a fire inspection before any daycare use could legally start. I turned down a request on that property once, mainly because the retrofit for a compliant second exit would have cost roughly 380,000 yen, and the tenant wasn’t planning to stay long enough to make that investment worthwhile for either of us.
My Insurance and Liability Conversation

This is the part I never skip, even when a tenant is in a hurry to get started. My landlord insurance policy covers fire and structural damage for a residential rental, but it does not automatically cover liability if a child is injured during a business activity on the property. Before I approve anything, I require the tenant to carry their own daycare liability insurance and show me proof, a copy of the actual policy, not just a verbal promise. I also call my own insurance agent and get written confirmation that my policy stays valid once business use begins. In one case my premium went up by about 8% once the insurer learned part of the house was being used commercially, and I passed that along as a 3,000 yen monthly addition to the rent, which the tenant accepted without much pushback.
Physical Changes I Actually Approved
Tenants running a daycare usually want to modify the space somehow: fencing off a play area, adding a gate at the top of the stairs, or building extra storage for toys and supplies. I approved safety gates on the stairs and a low fence around a 15-square-meter section of the yard, both paid for by the tenant and both removable at move-out with no damage to the property. I did not approve a request to knock down a wall between two rooms to make one larger play space, because that’s a structural change, and structural changes on any of my 9 properties go through me and a licensed contractor, full stop, no matter how reasonable the request sounds on the surface.
The Checklist I Run Before Signing Off
After going through this process a few times, I put together a short checklist that keeps the conversation focused and stops me from forgetting a step when a tenant is eager to start quickly.
- Confirm the zoning allows the number of children they plan to care for
- Ask for proof of daycare liability insurance before anything begins
- Call my own insurance agent to check whether my premium or coverage changes
- Put any lease amendment in writing, signed by both of us, before the daycare opens
- Agree in advance on which physical changes are allowed and who pays for them
- Set a review date, usually 6 months out, to confirm everything is working as planned
I’ve approved 2 of these requests over the years and turned down 1, and in every approved case the process above took about a week of phone calls and paperwork before I signed anything. That’s the approach I use across all 9 of my properties: say yes when it’s workable, but only after I’ve actually checked the details instead of going with a good feeling in the moment.
