Building Maintenance Reserve Fund: Why Every Building Needs One and How to Run It Transparently

Most disputes between neighbours start with money, and they almost always erupt at the worst possible moment: when something breaks without warning. The lift stops working, a shared pipe bursts, the boiler fails, and suddenly a large bill has to be paid right now. If nothing has been set aside beforehand, the building manager has to collect the money in the middle of the crisis. Some owners have no cash on hand, some argue it was not their fault, and some simply refuse to pay. The result is delayed repairs, further deterioration, and broken trust between residents. All of this tension is solved by one simple tool: a maintenance reserve fund, also called a sinking fund.

What a reserve fund is and why it matters

A reserve fund is money that residents set aside regularly, in advance, for the building’s large and future costs. It is not for the ordinary monthly expenses such as cleaning, lighting the common areas, or minor upkeep. It is for the heavy costs that come around every few years: a major lift overhaul, repainting and restoring the facade, replacing pumps and the boiler, roof waterproofing, and repiping. The logic is simple. Instead of paying one crippling sum in a moment of crisis, everyone pays a small share over time so that the money is ready when the failure arrives. This keeps repairs fast, protects the value of the property, and, above all, prevents arguments.

How to size and collect it fairly

• Base it on floor area or ownership share: the fairest method is to set each unit’s contribution in proportion to its size or ownership share, not equally, so a larger apartment pays more.
• Estimate long-term costs: assess the useful life of the lift, pumps, facade paint, and roof, then divide the future replacement cost over the number of months to reach a monthly share.
• Fixed and regular amounts: agree on a set monthly figure so the fund grows steadily without pressure; irregular, last-minute payments do not work.
• Keep it separate from monthly charges: never mix reserve money with the ordinary monthly service charge; they have two accounts and two purposes.
• Approve it collectively: agree the amount and method at the owners’ meeting and put it in writing so everyone consents in advance.

Keeping it transparent and accountable

• A separate ledger: the reserve fund must have its own independent account and ledger so it is never blended with running costs.
• Every contribution and expense recorded: each payment from residents and each withdrawal from the fund should be logged with date, amount, and description; no transaction should exist without a record.
• Residents can see the balance: every resident should be able to view the fund’s current balance and their own payment history; transparency removes suspicion.
• Regular reports: publish a monthly or quarterly report of the balance, contributions, and expenses so the manager is always accountable and no one feels anything is hidden.

Our recommendation

Keeping these accounts on paper or in a manual file quickly leads to errors, forgotten entries, and suspicion. That is why we recommend the Hamkhoneh building management software. Hamkhoneh keeps the reserve fund under its own category, separate from the monthly charge, records every contribution and expense, and produces clear reports and a management dashboard, so there is no longer any room for doubt or dispute.

Frequently Asked Questions

How is a reserve fund different from the monthly service charge?

The monthly service charge covers day-to-day running costs such as cleaning, security, and common-area electricity, while the reserve fund is savings for large future costs such as a lift overhaul or facade restoration. The two should be kept completely separate.

What happens if a resident does not pay their share?

When the amount has been approved at the owners’ meeting and put in writing, it is enforceable like the regular charge. The software records each unit’s debt precisely, and that transparency makes follow-up and agreement far easier and calmer.

How much should the reserve fund be?

There is no single figure that fits every building. The amount should be based on the age and cost of the building’s equipment and the size of each unit. A long-term estimate of future expenses reveals the fair monthly share.
