Introduction

This is the long-form companion to a question every shared apartment eventually asks: how do we actually do this fairly? Not in theory — in practice. With three flatmates, a hob that nobody quite owns, and Saturday morning dishes that materialise out of nowhere.

The good news: the answer isn't a personality fix. It's a structural one. Almost any group of reasonable people, given the right structure, will end up with a fair flat. Almost no group, no matter how reasonable, will get there without one. That's what this guide is about.

Why most systems fail

Before the principles, the failure modes. Most chore systems fail for one of four reasons:

  • The bookkeeper problem. The person who maintains the rota also does the chores, and quits both at once.
  • The visibility problem. Nobody can see contributions in one place. Each flatmate is keeping a private ledger.
  • The flat-effort problem. Cleaning the bathroom and watering one plant are both counted as "one task".
  • The rigidity problem. The rota doesn't bend for weekends away, illness, or work crunches, so the first time real life happens, it breaks.

A working system fixes all four. None is optional.

The five principles of fair division

  1. Effort, not just count. Tasks have different weights. A 3-minute task and a 30-minute task should not be treated as equivalent contributions.
  2. Rotation, not assignment. Static "you do dishes, I do bins" allocations break down the moment one person's situation changes. Rotation handles this automatically.
  3. Shared visibility. Every flatmate sees the same data, in real time. There is no master and no audit trail held by one person.
  4. Off-duty hours. Real life is uneven. The system has to know when someone's on holiday, in deadline week, or recovering from flu.
  5. A single number. Disputes happen on lists. Resolution happens on numbers. A live fairness score is the artefact you point at.

Step-by-step setup

Step 1: List the recurring tasks honestly

Sit down together. Brainstorm everything that needs to happen weekly, monthly, or once a quarter. Don't filter. Bins, dishes, hoovering, kitchen deep clean, bathroom, plant care, laundry of shared linens, cat, taking out recycling, replenishing toilet roll. The full list. You'll prune later.

Step 2: Effort-weight every task

Use a 1–5 scale. 1 = under 5 minutes, 5 = a 30+ minute or unpleasant job. Be honest. The bathroom is a 4 or 5. Watering one plant is a 1. If your group disagrees on a weight, take the higher number — overestimating effort is far less damaging than underestimating it.

Step 3: Set frequency

Daily, twice-weekly, weekly, monthly. Be realistic. A "monthly fridge deep clean" that nobody actually does monthly is worse than a quarterly one that does happen.

Step 4: Let the system rotate

Don't pre-assign. Let an automated rotation distribute tasks across flatmates with effort balancing in mind. The first week may feel uneven; by week three, the cumulative effort points should be very close across everyone.

Step 5: Make the score visible

The fairness score should be on every flatmate's phone. Glanceable, not buried. The whole point is that nobody has to ask for a status update — they can see one.

Templates: a starting list for a 3-bed flat

Adapt this; don't copy verbatim. Effort points in brackets.

  • Bins out (2) — weekly
  • Recycling out (1) — fortnightly
  • Kitchen surfaces wipe-down (2) — twice weekly
  • Hoover communal areas (3) — weekly
  • Mop kitchen floor (2) — weekly
  • Bathroom deep clean (4) — weekly
  • Bathroom quick clean (2) — twice weekly
  • Replenish toilet roll, soap, washing-up liquid (1) — as needed
  • Fridge clear-out and wipe (3) — monthly
  • Oven clean (5) — monthly
  • Window cleaning, communal (4) — quarterly

Using technology to actually run it

You can run this on paper. You will not run this on paper for long. The bookkeeper problem will end you. The minimum tech stack is something that:

  • Holds the task list with effort weights;
  • Rotates assignments automatically across flatmates;
  • Sends reminders before tasks are due;
  • Computes a live fairness score everyone can see;
  • Respects off-duty hours.

This is exactly what Nudge does. There are alternatives, and almost any of them is better than a fridge whiteboard. The point is to pick one and use it for at least three weeks before judging it.

Conclusion

Fair chore division isn't a matter of finding the right people. It's a matter of building the right structure around the people you've already got. Put effort weights, rotation, visibility, off-duty hours, and a single shared score in place — and most apartments find that the chore conversation simply stops needing to happen.

Try it for three weeks. If it's not visibly better than what you had before, scrap it. But you probably won't.
