Singapore Strata Management (BMSMA) & MCST Condo Bylaws Guide 2026

Statutory Overview & Housing Framework

Strata-titled condominiums and other private strata developments in Singapore are governed primarily by the Building (Strata Management) Act 2004 (BMSMA), together with its regulations, the Land Titles (Strata) Act and the property's registered bylaws. The Building and Construction Authority (BCA) administers the strata-management regulatory framework and provides MCST resources and e-services. Once a Management Corporation Strata Title (MCST) is constituted, the subsidiary proprietors of the lots form the management corporation for the strata title plan. The MCST is responsible for the management and maintenance of common property and operates a management fund and a sinking fund. Contributions are determined by the MCST through ordinary resolutions and are generally payable by subsidiary proprietors in proportions corresponding to the share values of their lots. Share value is not merely a fee multiplier: under section 62 of the BMSMA it determines the proprietor's voting rights, the quantum of the undivided share in common property and, subject to statutory exceptions, the amount of contributions that may be levied. The source page's statement that share value is simply based on floor area is therefore too simplistic; BCA allocates share values under the statutory schedule-of-strata-units framework. Bylaws are also not just informal estate rules. An MCST may make bylaws governing common property and related matters, and a bylaw generally requires a special resolution. A special resolution is not '75% of all owners': on a poll, the votes in favour must represent at least 75% of the aggregate share value of all valid votes cast by subsidiary proprietors present in person or by proxy, and the statutory notice and meeting requirements must also be satisfied. Bylaws must also be lodged with the Commissioner where the BMSMA requires. The original page's maintenance-interest claim is inaccurate: section 40(6) allows interest at the rate determined by the MCST on contributions remaining unpaid 30 days after becoming due, and section 107 allows the Strata Titles Board to vary an unreasonable rate. A rate of 15% may be used by some MCSTs, but it is not a universal statutory rate. Unpaid contributions can ultimately become a registered charge on the lot after the statutory demand and registration process under section 43, and the MC can have powers of sale subject to the Act's safeguards; a registered charge is not a caveat. The Strata Titles Boards are quasi-judicial tribunals with jurisdiction over specified strata disputes, including inter-floor water leakage, disputes concerning duties under the BMSMA or bylaws, invalidation/revocation of resolutions or bylaws, contribution and interest disputes, access to lots and other matters listed in Part VI. For inter-floor water leakage, BCA materials state that water seepage appearing on a lower-floor ceiling is presumed to originate from the upper-floor unit unless the upper-floor owner or occupier proves otherwise. This statutory presumption does not mean that the upper owner automatically pays '50% to 100%' of every repair bill; responsibility and the appropriate orders depend on the source, investigation, repairs, evidence and the STB/other applicable legal process. URA separately regulates private-residential rental use: private residential properties must generally be rented for at least three consecutive months, and stays below three months are illegal short-term accommodation. Court fines can reach S$200,000 per charge under the Planning Act in prosecuted cases. The temporary occupancy relaxation allows qualifying private residential properties of at least 90 sqm to house up to eight unrelated persons until 31 December 2028, but registration/authorisation is required; the normal cap remains six unrelated persons. A complete MCST guide therefore needs to distinguish statutory BMSMA rights, registered bylaws, council powers, general-meeting resolutions, individual-unit responsibilities, STB jurisdiction and separate URA planning/rental rules.

Key Statutory Rules & Housing Criteria

What is an MCST?

A Management Corporation Strata Title (MCST) is the management corporation constituted for a strata title plan. The subsidiary proprietors of the lots form the management corporation and, under the BMSMA, the MCST manages and maintains common property and exercises the statutory powers and duties assigned to it. The MCST is separate from the managing agent: the managing agent is a service provider appointed to perform delegated functions, while the MCST remains the statutory management body. The council of the MCST handles the day-to-day governance within the powers and restrictions provided by the BMSMA and the general body.

What does the MCST manage?

The MCST's core statutory responsibility is the management and maintenance of common property. This can include common structures, roofs, facades, lifts, external areas, corridors, facilities and other property falling within the statutory/common-property framework. The MCST can carry out work on common property, maintain the common areas in good and serviceable repair, insure the subdivided building as required and collect contributions needed to meet its liabilities. Owners remain responsible for matters relating to their individual lots, subject to the BMSMA, the property's bylaws and the exact location/classification of the affected component.

Management fund versus sinking fund

The BMSMA requires the MCST to maintain a management fund and a sinking fund. The management fund receives contributions for regular maintenance, common expenses, insurance and other liabilities arising in the ordinary management period. The sinking fund is used for major repairs and improvements, painting/treatment, renewal or replacement of common property and other future liabilities that the legislation permits to be funded from the sinking fund. The source page's wording that both funds are simply 'monthly maintenance fees' is therefore incomplete.

How does share value work?

Share value is a statutory concept attached to each strata lot. Section 62 of the BMSMA states that the share value determines the subsidiary proprietor's voting rights, the quantum of the owner's undivided share in the common property and, subject to statutory exceptions, the amount of contributions that may be levied by the MCST. It is therefore not accurate to say that share value simply equals floor area or that it only determines monthly fees. BCA's share-value framework is part of the schedule of strata units and related Commissioner processes.

Is the monthly MCST fee calculated solely by multiplying share value?

Share value establishes the statutory proportion for contributions, but an MCST first determines the total amount it reasonably and necessarily needs to raise for its management and sinking-fund liabilities through the appropriate resolutions. Those contributions are then generally payable by subsidiary proprietors in shares proportional to their lots' share values, subject to the Act's exceptions. A unit with share value 5 in a development with total share value 500 would therefore ordinarily bear 1% of a contribution that is allocated proportionally by share value, but the actual monthly bill depends on the MCST's approved contribution amount and any lawful additional or varied contribution.

How are MCST contributions approved?

Section 39 requires the MCST to determine by ordinary resolution the reasonable and necessary amounts to be raised for the management fund and sinking fund for the relevant period. Contributions are generally payable in proportions corresponding to share values. The MCST can also levy additional or varied contributions under section 41 and related provisions. Owners should therefore distinguish between the annual/general determination of contributions, later special or additional contributions, and ad hoc expenses incurred within the MCST's statutory powers.

How much voting power does a condo owner have?

A condo owner does not simply receive one equal vote for every motion. The BMSMA uses different voting rules depending on the type of resolution and whether a poll is taken. BCA's current guidance states that when a poll is called, voting is based on the share value of the lot. For special resolutions, the motion must satisfy the statutory meeting/notice requirements and, on a poll, the votes in favour must represent at least 75% of the aggregate share value of all valid votes cast by subsidiary proprietors who are present in person or by proxy. The original phrase '75% at the AGM' is therefore incomplete: the denominator is the aggregate share value of all valid votes cast at the relevant meeting, not 75% of every owner in the development.

What are MCST bylaws?

Bylaws are legally recognised rules made under the BMSMA framework to regulate the use and management of common property and other permitted matters. They can cover matters such as behaviour on common property, obstruction, parking-related controls, nuisance, use of facilities and other issues permitted by the Act. Exclusive-use bylaws have their own statutory requirements. A bylaw is not valid merely because a managing agent puts a notice on a lift: the MCST must have the legal power to make it and must use the required special resolution and registration/lodgment process. A bylaw that exceeds the MCST's legal power can be challenged before the Strata Titles Board.

Does a condo bylaw require a 75% vote?

A bylaw generally requires a special resolution under the BMSMA framework. A special resolution is not simply '75% of all unit owners'. The statute defines the voting threshold using the aggregate share value of valid votes cast by subsidiary proprietors present in person or by proxy, together with statutory notice and meeting requirements. BCA's strata-management guide gives the same explanation. In addition, bylaws made under the BMSMA must be lodged with the Commissioner in accordance with the Act. A new rule concerning pets, use of facilities or other common-property matters therefore needs to be checked against both the Act and the development's existing bylaws before enforcement.

What happens if an owner does not pay MCST contributions?

Unpaid MCST contributions do not automatically attract a fixed statutory 15% interest rate. Under section 40(6), if a contribution remains unpaid on or before the 30th day after it becomes due, it bears interest at the rate determined by the MCST, unless the MCST determines that no interest should be charged. Section 107 also allows the Strata Titles Board to vary an unreasonable interest rate. If an amount or contribution remains unpaid after the statutory demand process, the MCST can lodge an instrument of charge; once registered, the amount and interest can constitute a registered charge on the lot, and the MC has statutory enforcement powers subject to safeguards; a registered charge is not a caveat.

Can an MCST sell a lot for unpaid contributions?

The BMSMA provides an enforcement route after a registered charge has been created. The MCST cannot simply seize or sell a unit because one payment is late. Section 43 sets out safeguards, including a special resolution to have the lot sold, publication of the intended sale in an approved daily newspaper and a waiting period during which specified sums remain unpaid. The exact enforcement steps should be followed carefully because a prior mortgage or other prior encumbrance can affect the MCST's position.

What is the Strata Titles Board (STB)?

The Strata Titles Boards are quasi-judicial tribunals established under Part VI of the BMSMA. BCA and STB materials state that they can mediate and determine specified disputes between subsidiary proprietors, between subsidiary proprietors and MCSTs and in other categories set out in the Act. Examples include inter-floor water leakage, disputes over the exercise of duties under the BMSMA or bylaws, applications to convene meetings, invalidate or nullify resolutions, revoke or invalidate bylaws, vary contribution or interest decisions, obtain access to lots and require documents. STB is not a general-purpose court for every condominium dispute and it cannot decide title-to-land questions.

Inter-floor water leakage: is the upper-floor owner automatically liable?

BCA's guidance states that where water seepage appears on a lower-floor ceiling, the law presumes that the leak is presumed to originate from the upper-floor unit unless the upper-floor owner or occupier proves otherwise. The parties are encouraged to jointly investigate the source and resolve the repair method and cost privately first. If the parties cannot resolve the matter, the MCST can assist and an application can be made to the Strata Titles Board. The original statement that the upper owner is automatically liable for '50% to 100%' of all repair costs is therefore incorrect: it is not a universal 50:50 or not a universal 50%-100% statutory rule. The statutory presumption concerns the origin of the leakage; the actual order and cost allocation depend on the evidence, source, repairs and the applicable legal process.

Can MCST bylaws ban pets, regulate facilities or control parking?

An MCST can make bylaws concerning the use and management of common property and can regulate permitted matters within the BMSMA framework. However, a bylaw cannot simply conflict with the Act, another written law or the legal rights of subsidiary proprietors. An advertised rule about pets, a swimming pool, BBQ areas, renovations or parking should therefore be checked against the registered bylaws and the resolution by which it was made. Exclusive-use arrangements are subject to specific BMSMA requirements and may require a higher form of resolution depending on duration and structure.

Can an MCST ban Airbnb or stays shorter than three months?

The legal ban on short-term accommodation does not come from the MCST alone. URA's planning rule applies to private residential property across Singapore and requires a minimum stay of three consecutive months. Stays below three months are prohibited as short-term accommodation. MCSTs can assist URA with enforcement, tighten security measures and use their own lawful bylaws for estate-management purposes, but a condo's internal rule is not the source of the three-month statutory requirement. URA states that individuals involved in short-term accommodation can face fines under the Planning Act, and prosecuted charges can carry court fines of up to S$200,000 per charge.

Private-condo occupancy cap in 2026

The occupancy cap is separate from the minimum-stay rule. URA states that private residential properties are generally subject to a maximum of six unrelated occupants. Since January 2024, owners of qualifying private residential properties of at least 90 sqm can apply for temporary relaxation registration/authorisation allowing up to 8 unrelated persons. On 16 January 2026, URA announced that the relaxation would be extended until 31 December 2028. The eight-person cap is therefore not automatic for every condominium: the property must meet the size criterion and the owner must complete the applicable temporary registration. Owners should also check whether the MCST has additional lawful occupancy-registration or security bylaws.

What documents should a condo owner request from the MCST?

A buyer, owner or prospective council member may need information beyond the monthly maintenance statement. Depending on the issue, useful records can include the registered bylaws, latest AGM and EGM minutes, audited accounts, management/sinking-fund statements, contribution levies, insurance information, repair or maintenance contracts, notices of proposed major works and relevant correspondence. The BMSMA contains provisions governing the MCST's records and supply of information, and the STB can hear applications to supply documents in specified circumstances. A managing agent's refusal should therefore be assessed against the statutory access rights and the precise document requested.

A practical MCST dispute workflow

Owners should first identify whether the dispute concerns an ordinary management decision, a bylaw, a contribution, common-property repair, an individual lot, an inter-floor leak or another statutory category. The owner should then obtain the relevant documents and make a written request to the MCST or managing agent. If the issue cannot be resolved, the owner should check the STB's jurisdiction under Part VI of the BMSMA. Some matters have different statutory routes, while title-to-land disputes fall outside STB jurisdiction. For urgent physical problems such as water leakage, parties should prioritise inspection and mitigation before turning the dispute into a compensation claim.

What is not automatically an MCST responsibility?

The MCST is responsible for common property and its statutory duties, but not every problem inside a lot is automatically an MCST repair obligation. Responsibility depends on whether the affected item is part of common property, the individual lot, limited common property, a service serving multiple lots, or another legally defined component. The same physical symptom can have different legal responsibility depending on its source. For example, inter-floor water leakage may invoke the statutory presumption and STB process, while an appliance or internal fitting entirely within one lot may remain the lot owner's responsibility. Owners should identify the affected component and its legal classification before demanding payment from the MCST.
