There are two ways a house works: everyone happens to have the same habits, or there are clear agreements. The first is luck. The second can be built.
Why cleaning rotas fail
The chart on the fridge is the first thing almost everyone does, and it almost always fails for the same reason: it assigns tasks but never defines what doing them means. “Kitchen: Marta, week 3” doesn't say whether that includes the fridge, the floor, or just the worktop.
When the standard isn't defined, everyone applies their own, and two months in someone is convinced they clean twice as much as everyone else. Usually two people are convinced of that at the same time.
The four rules you actually need
A house doesn't need a rulebook. It needs to settle the four places where living together breaks down.
1. The state shared spaces are left in
Defined as an outcome, with a deadline. Not “be tidy”, but “whatever you make dirty in the kitchen, you clear the same day”.
2. What time noise comes down
One time on weeknights and another at the weekend. With an agreed time, asking for quiet stops being a personal complaint and becomes a reminder of something already settled.
3. How guests are flagged
Nobody needs permission. You just need to agree what gets mentioned: usually anyone staying the night, and any group beyond two or three people.
4. How shared costs get paid
Who fronts the money, how often it's settled, and where it's written down. It's the rule that prevents the most arguments and the one fewest people write.
House agreement template
To copy and fill in together on day one. It isn't a contract and has no legal weight: its job is to get expectations said out loud while there's still no conflict.
- Shared spaces: whatever you make dirty, you clear before bed. Deep clean happens on ___ each week.
- Noise: volume comes down after ___ on weeknights and after ___ at weekends.
- Guests: flag it in the group if someone stays over or if more than ___ people are coming.
- Bills: ___ fronts them and they're settled on the ___ of each month.
- Food: the basics are shared (___), the rest is individual.
- If something bothers you: say it to the person directly, that same week.
- Review: we read this again in three months.
Changing something that stopped working
Circumstances change: someone starts working from home, someone gets a partner, someone's shifts move. Most flatshare conflicts after month six are old agreements applied to a new situation.
- 1.Raise it away from the moment of conflict, not in the heat of it.
- 2.Describe the situation, not the person: “the cleaning is piling up” rather than “you don't clean”.
- 3.Propose something concrete and give it a trial period.
- 4.Look at it again a few weeks later.
