Sinking fund under the MUD Act 2011: how much should your OMC collect?

Under section 19 of the Multi-Unit Developments Act 2011, the owners' management company (OMC) of an apartment development must keep a sinking fund in a separate account for refurbishment, improvement and non-recurring maintenance. Each unit pays €200 a year unless a meeting of the members agrees a different amount. That figure is a default, not a target: the right sinking fund contribution is whatever covers the roof, lift, fire alarm and render when they fall due.

Set the fund too low and the bill still arrives – as a special levy, usually in the same year as the work, and usually with arrears. This guide explains what the Act requires, how to size the fund from the building's components and how to put the numbers to the AGM, with a worked example for a 24-apartment block.

What the MUD Act 2011 says about the sinking fund

Section 19 sets out six rules that every board should know:

• Purpose. The fund – the Act also calls it a "building investment fund" – pays for refurbishment, improvement, maintenance of a non-recurring nature and advice from a suitably qualified person on those works.
• Non-recurring maintenance needs two approvals. The directors must certify the spend as non-recurring, and a meeting of the members must approve it as such (s.19(2)).
• Everyone pays. Every unit owner contributes, including the developer for unsold units (s.19(3)).
• Amount. €200 per unit per year "or such other amount as may be agreed by a meeting of the members" (s.19(5)).
• Start date. The obligation applies three years after the first unit is transferred, or from 1 October 2012 (18 months after the section commenced), whichever is later.
• Ring-fenced. Contributions sit in a separate account and cannot be spent on anything else (s.19(7)).

The day-to-day costs go through the annual service charge under section 18. The OMC can bill both together, and under section 21 every request for payment – combined or not – must show the basis of the calculation, a breakdown and the amount for that unit.

Sections 17 to 22 apply even to small developments of two to four homes. The exception is a development where the OMC owns only the shared grounds, not the buildings – typically an estate of houses. There a sinking fund is optional, but if one exists the section 19 rules apply to it (s.20).

The €200 default – and why it is rarely enough

The €200 figure has not changed since 2011, and no regulations have been made under section 19(9) to set a different method. In its 2024 report on the real cost of apartment block maintenance, the Society of Chartered Surveyors Ireland found that:

• 88% of property managers said they manage developments without an adequate sinking fund, and about 1 in 10 developments has none at all;
• owners typically pay €200 to €300 per unit a year;
• its nine Dublin case studies needed about €2,000 per unit a year over a 20-year horizon.

There is a second reason to fund properly. The State's planned scheme for apartment defects will not pay where sinking funds did not plan for replacing building and safety systems at the end of their life. The government's defects working group drew the same line in 2022: defects are one thing, end-of-life replacement is the OMC's job.

Step by step: sizing the fund from the building's components

The professional method is a Building Investment Fund (BIF) report, usually prepared by a chartered or registered building surveyor. The SCSI's client guide of May 2026 recommends updating it every four or five years and giving every owner a copy. The logic behind it is simple enough for a board to follow – and to check:

1. List the common-area components the OMC owns: roof, lifts, fire alarm, emergency lighting, render and paint, windows and doors, corridors, car park, gates, pumps. The head lease shows what is common area and what belongs to each apartment.
2. Record when each was last done and its expected life. Next due = last done + life, unless the condition survey says sooner.
3. Price each one today, including VAT and professional fees, then add an inflation allowance for the year it falls due.
4. Start from the current balance of the sinking fund account.
5. Find the lowest yearly contribution that keeps the balance above zero in every year of the plan. The year that sets the figure is usually the biggest single job, not the last one.
6. Add a margin so one surprise does not empty the account.

A newer development may also have a building lifecycle report from its planning application. Citizens Information notes it can help the OMC set both the service charge and the sinking fund contribution.

Worked example: a 24-apartment block over 10 years

Two limits of a 10-year view: components due in year 11 or later are invisible, and the lift and roof will need replacing again. That is why BIF reports usually look 20 years ahead, and why the SCSI case studies arrive at higher figures than this example.

Splitting the contribution between units

The Act sets no formula. Section 19(5) fixes the sinking fund contribution "as respects a unit", and the service charge must be "calculated on a transparent basis" and "equitably apportioned" (s.18(13)). In practice the split comes from the head lease – by property type, floor area or position in the building, as the Housing Agency's guide for OMC directors explains. Harbour View's lease gives each unit type a fixed share, and the board asks the AGM to agree the sinking fund contribution on the same shares:

The total combines the service charge (share × €60,000) and the sinking fund (share × €24,000). The 24 units together pay €84,000, exactly the budget. Billed quarterly, a 2-bed pays €903 a quarter. If your lease or constitution sets a different basis for the sinking fund – for example a flat amount per unit – follow it, and say so on the invoice.

Presenting the budget and sinking fund at the AGM

Section 17 requires an annual report and a meeting at least once a year. Members get at least 21 days' notice of the meeting and the report at least 10 days before it. Alongside the accounts, insurance details and the service charge, the report must show:

• the funds standing to the credit of the sinking fund;
• the annual contribution and the basis on which it is calculated;
• any refurbishment, improvement or non-recurring maintenance planned for the current period;
• in general terms, the fire safety equipment installed and how it is maintained.

For the last point, a fire safety register with service due dates for the alarm and emergency lighting gives the board the evidence in one place. Lift and pump servicing can be tracked the same way in a preventive maintenance schedule, which also helps when the surveyor asks when each item was last done.

The service charge itself cannot be levied until a general meeting has considered the estimate (s.18(2)). Members can amend the proposal with 60% of those present and voting. If at least 75% of those present and voting reject it, last year's charge continues until a new one is adopted. For the sinking fund, s.19(5) only requires a different amount to be "agreed by a meeting of the members".

What wins the vote is usually the comparison: the yearly increase per unit against the special levy that the €200 plan would trigger in the lift year. Show the projection, not just the total.

Most boards rely on a managing agent for the figures. Agents must hold a Property Services Regulatory Authority licence for property management (type D) and give the OMC a letter of engagement setting out the services, as Citizens Information explains. The directors remain responsible for the budget.

What may change in 2026 and 2027

• MUD Act review. The national housing plan Delivering Homes, Building Communities 2025–2030 commits to moving responsibility for the Act to the Department of Housing, which will then review it. Action 8.4 – "strengthen the operation of management companies" under the Act – has a target of H1 2027.
• Defects scheme. As of 21 October 2026, the Apartment and Duplex Defects Remediation Bill has not been published. In the meantime, OMCs apply to the Housing Agency's interim scheme for urgent fire safety works.
• The €200 figure. The SCSI has called for it to be removed from the Act. Until the law changes, s.19(5) applies as written.
