Sharing a Flat with Roommates: Rules, Costs and Agreements

With rents in Dhaka and other big cities taking a large share of monthly income, sharing a flat with roommates has become a normal choice for students, young professionals, and people who have just moved to the city for work. Two, three or four people splitting a flat can live in a better area and a safer building than any of them could afford alone. But shared living also brings its own problems: who pays how much for the bigger room, whose turn it is to buy the gas cylinder, what happens when one roommate leaves suddenly in the middle of the month, and how to deal with a landlord who only wants to talk to one person.

This guide explains how to set up a fair and peaceful shared flat with roommates in Bangladesh. You will learn how to split rent and bills fairly, what to agree with the landlord, how to write a simple roommate agreement, house rules that actually work, and how to handle a roommate leaving. There is also a section for landlords who rent to groups of sharers.

Shared Flat vs Mess vs Sublet: Know What You Are Entering

People use different words for shared living in Bangladesh, and the arrangement affects your rights and responsibilities.

This guide focuses on the first type, where a group rents a flat together, but most of the tips on money and house rules apply to messes and sublets too. If you are subletting, check your rental agreement first: many agreements in Bangladesh prohibit subletting without the landlord's written consent.

Step 1: Choose Roommates Carefully

The best rules cannot fix a badly matched household. Before committing to a flat together, have an honest conversation about:

• Budget: what each person can comfortably pay every month, including bills.
• Income stability: is everyone's income regular? A student relying on tuition income may have gaps.
• Daily routine: night-shift workers, early risers and students preparing for exams have different needs.
• Cleanliness and cooking: will you cook together, separately, or hire a cook (bua)?
• Guests: how often, how late, and whether overnight guests are acceptable.
• Smoking and other habits: agree clearly before moving in.
• How long everyone plans to stay: a roommate leaving after three months puts pressure on everyone else.

Friends do not always make good roommates, and strangers can become great ones. What matters is compatible habits and honest communication.

Step 2: Agree with the Landlord on Who Is the Tenant

Landlords in Bangladesh vary a lot in how they handle shared flats. Some prefer a single "lead tenant" who signs the agreement and pays the full rent; others want every sharer named. Before signing, clarify:

• Whose names will be on the rental agreement?
• Who will pay the security deposit (jamanat) and advance, and how will it be returned?
• Will the landlord accept rent from each person separately, or only one payment for the whole flat?
• What happens if one roommate leaves — can a replacement join, and does the landlord need to approve them?
• Are there building rules on visitors, gate time or bachelor tenants?

Every adult occupant should normally provide identity details for the police tenant information form (in Dhaka, the DMP form), even if only one person signs the agreement. Our guide on questions to ask a landlord before renting covers more points to confirm.

Tip for lead tenants: if your name alone is on the agreement, you are the one the landlord will hold responsible for the full rent and any damage. Protect yourself with a written roommate agreement and collect shares before the rent due date, not after.

Step 3: Split Rent Fairly

An equal split is simple, but it is not always fair. Rooms often differ in size, attached bathroom, balcony, light and privacy. Common approaches:

Equal split

Everyone pays the same. This works when rooms are similar or when roommates rotate rooms.

Room-weighted split

Assign points to each room based on size and features, then divide rent in proportion.

For example (illustrative): three friends rent a flat for Tk 27,000 per month.

• Room A (master bedroom with attached bath and balcony): 4 points
• Room B (medium bedroom, attached bath): 3 points
• Room C (small bedroom, shared bath): 2 points

Total points: 4 + 3 + 2 = 9. Value per point: Tk 27,000 ÷ 9 = Tk 3,000.

• Room A pays 4 × Tk 3,000 = Tk 12,000
• Room B pays 3 × Tk 3,000 = Tk 9,000
• Room C pays 2 × Tk 3,000 = Tk 6,000

Check: Tk 12,000 + Tk 9,000 + Tk 6,000 = Tk 27,000. Everyone can see how the numbers were reached, which prevents resentment later.

Couple or double-occupancy rooms

If two people share one room, it is reasonable for that room to pay a bit more for common costs such as utilities, since more people use them, even if the rent share for the room itself stays the same.

Step 4: Split Bills and Shared Costs

Bills cause more arguments in shared flats than rent does, because they change every month. Make a list of all shared costs and decide how each will be split.

For a clear overview of who normally pays what in rented flats, read utility bills in a rented flat in Bangladesh.

The meal-rate system

Many shared households in Bangladesh use a simple meal system: each person marks how many meals they ate in a month, the total grocery spend is divided by total meals to get a "meal rate", and each person pays their meal count multiplied by that rate. For example (illustrative): if total grocery spending is Tk 18,000 and 240 meals were eaten, the meal rate is Tk 18,000 ÷ 240 = Tk 75. A roommate who ate 90 meals pays 90 × Tk 75 = Tk 6,750. This is fair to people who eat out often or travel home on weekends.

Step 5: Write a Simple Roommate Agreement

A roommate agreement is a private written understanding between sharers. It does not replace the rental agreement with the landlord, but it makes expectations clear and gives you something to refer back to. It can be one or two pages. Include:

1. Names, contact numbers and home addresses/emergency contacts of all roommates.
2. Which room each person occupies and their monthly rent share.
3. How and by what date each person pays their share to the lead tenant or the landlord.
4. How each bill is split and who manages payment.
5. Each person's share of the security deposit and advance, and how it will be returned.
6. Notice required before leaving (for example, one or two months) and the obligation to pay until a replacement is found or the notice period ends.
7. How new roommates are chosen and approved.
8. House rules (see below).
9. How disagreements will be resolved — for example, a house meeting first.

Sample clause: "Any roommate who wishes to leave will give at least 30 days' written notice to the others. The leaving roommate remains responsible for their share of rent and bills until the end of the notice period or until an approved replacement moves in, whichever is earlier. Their share of the security deposit will be paid back by the incoming roommate or from the deposit refund at the end of the tenancy."

House Rules That Actually Work

Keep house rules short, specific and agreed by everyone. Put them on a sheet in the kitchen or in your group chat. Useful areas:

• Cleaning roster: a weekly rota for the kitchen, bathrooms, common room and taking out rubbish.
• Kitchen: wash your dishes the same day; label personal food in the fridge.
• Quiet hours: for example, 11 pm to 7 am on weekdays, especially during exams.
• Guests: inform roommates in advance for overnight guests; follow the building's visitor and gate rules.
• Security: lock the main door, do not share keys with outsiders, switch off gas and iron before leaving.
• Energy use: turn off fans, lights and AC when leaving a room; be careful during load-shedding if the IPS or generator is limited.
• Money: shares paid by a fixed date each month; receipts or screenshots shared in the group.

Managing Money Transparently

Most roommate conflicts are really about money that nobody tracked properly. Some habits that help:

• Use one shared spreadsheet or app to record every payment and expense with date, amount and who paid.
• Pay shares by bKash, Nagad or bank transfer rather than cash, so there is a record.
• Settle up monthly, not "whenever". Small debts left for months become big arguments.
• Keep the landlord's rent receipts in the group, so everyone knows rent was actually paid.
• Plan for irregular costs: a new gas cylinder, a fan repair or the cook's festival bonus.

When a Roommate Leaves

People change jobs, get married or move back home. Handle departures in a structured way:

1. The leaving roommate gives written notice as per the roommate agreement.
2. Remaining roommates decide whether to find a replacement or take on the extra cost.
3. Inform the landlord and get approval for any new occupant; update the police tenant information where required.
4. Settle the leaving person's bills up to their last day.
5. Arrange repayment of their deposit share — usually by the incoming roommate paying it directly.
6. Check the leaving person's room for damage and collect keys.

Common Mistakes in Shared Flats

• No written agreement among roommates. Verbal understandings are forgotten or remembered differently.
• One person paying everything and waiting to be repaid. This creates debt and resentment.
• Ignoring the landlord's rules. Hidden extra occupants or unapproved sublets can lead to eviction notices.
• Not splitting deposits clearly. Years later, nobody remembers who paid what.
• Letting small issues build up. Hold a short house meeting monthly to raise concerns early.
• Choosing roommates only on budget. Lifestyle fit matters as much as money.

For Landlords: Renting to a Group of Sharers

Renting to working professionals or students who share can be stable and profitable if managed fairly. Good practice for landlords:

• Verify every adult occupant, not only the person who signs, and keep their details for the police tenant information form.
• Decide whether you want one lead tenant or all names on the agreement, and write the responsibility for rent clearly.
• Set a maximum number of occupants suitable for the flat's size and the building's facilities.
• Put rules on replacement roommates in writing: they must be approved and registered before moving in.
• Apply building rules equally to all tenants; treat sharers and families fairly and consistently.

Final Thoughts

Sharing a flat with roommates in Bangladesh can save you a lot of money and give you a better home than you could afford alone. The difference between a happy shared flat and a stressful one is usually preparation: choosing compatible people, being clear with the landlord, splitting costs by a method everyone understands, writing a short roommate agreement, and tracking money transparently every month.

For landlords with several shared or bachelor flats, Bariwala ERP (বাড়িওয়ালা ERP) can record each tenant profile with family or co-occupant details and NID verification, generate monthly invoices and receipts, and send SMS reminders — making it easier to keep clear records even when several people share one flat.
