A roommate app for multi-unit and multi-floor houses

Updated October 16, 2026

Most roommate apps assume one small group: three people, one kitchen, one list. Big shared houses don't work like that. A house with a basement unit, two floors of bedrooms, and a converted attic is really several small households sharing a building, some bills, and maybe a laundry room. Run it as one flat group and everyone gets everyone's noise: the top floor's bin rota, the basement's shopping list, forty messages about a kitchen they don't use.

What goes wrong in a multi-unit house

• One chat for everyone. It's too loud to follow, so people mute it, and then miss the one message that mattered.
• One quiet-hours rule for everyone. The floor of night-shift workers and the floor of early risers need different hours.
• Chores that don't fit. Each floor has its own kitchen or bathroom, but the bins and the hallway belong to the whole house. A single rotation either ignores that or gets rebuilt by hand every week.
• Shared machines across floors. Some floors have their own washer; there's also a shared one in the basement. Nobody knows which one is free.
• Who sees what. The basement's shopping list and repair requests aren't the attic's business.

How to organize a multi-unit house (with or without an app)

1. Draw the map. List each floor or unit, who lives there, and which spaces each one shares: kitchen, bathroom, laundry, outdoor space.
2. Sort every job by scope. For each chore, list, or rule, decide whether it belongs to one floor or the whole house. Floor kitchens are floor jobs; bins, stairs, and the front hall are house jobs.
3. Rotate house jobs between floors. Instead of putting twelve people in one bin rotation, alternate it between floors week by week and let each floor sort itself out.
4. Let each floor set its own quiet hours, with a house-wide minimum if the lease or neighbors need one. See reasonable quiet hours for roommates.
5. Split bills by how they're metered. Whole-house bills go to everyone; per-unit bills go to that unit. There's a full walk-through in how to split utilities in a multi-unit house.

How it works in hausync

Floors and units are optional in hausync. A two-person apartment ignores them. A bigger house adds them in house settings, each with a name and, if you like, a floor number, and assigns each housemate to one. An invite can carry a unit, so new people land on the right floor when they join.

Chat per floor

Every house has a House channel, and every floor gets its own channel. Floor channels are open to everyone in the house to read, so nothing is hidden, but the noise is sorted. Groups cover anything else, and direct messages stay private to the two people in them.

Quiet hours per floor

Each floor can have its own quiet hours, on the days of the week you choose. While a floor's quiet hours are on, a banner shows on the shared calendar.

Chore rotations between floors

A chore can rotate between people or between floors. With a floor rotation, the whole floor whose turn it is gets the reminder, and that floor can hand the turn to one person. A whole-house chore can also be switched off for a floor that doesn't use that space (the owner sets which floors skip it), and floor-only chores rotate just within that floor.

Floor-only lists, events, tickets, and machines

Shopping and to-do lists, calendar events, maintenance tickets, and laundry machines can belong to one floor or to the whole house. A housemate sees their own floor's things plus everything house-wide. House admins and the owner see every floor, which is what lets one person keep the building running. Laundry machines on a floor show only to that floor; the shared basement machine shows to everyone. See the laundry tracker.

Money stays between people

Expenses are never floor-wide: each one is visible only to the people who paid or share in it. For a bill split by floor, use shares, for example giving each person on a bigger floor a larger share, so the split matches the rule your house agreed.

Price for a big house

One subscription covers everyone in the house, priced by size: $8 a month for 2–6 people, $12 for 7–12, and $16 for 13 or more, after 14 days free. Housemates never pay; the owner does.

What hausync doesn't do

• It isn't property-management software: no rent collection, leases per unit, or tenant screening. It's for the people living in the house.
• Floor channels are readable by the whole house; there's no hidden floor channel. Use a group for a private conversation.
• A housemate belongs to one floor at a time.
• No automatic floor-based bill split; use shares or exact amounts.
• It doesn't move money between people.
