URA flags ‘persistent trend’ of suspected cases of unauthorised works in residential units
One example of such works is an enclosed structure on a private first-storey patio.
The Urban Redevelopment Authority (URA) has issued a warning regarding an increasing number of suspected cases of unauthorized works in residential units in Singapore. In 2024, the agency received 147 reports of such cases, and this number rose to 148 in 2025. By the end of the first nine months of 2026, there were already 116 reported cases.
These unauthorized works include the construction of lofts or mezzanine floors exceeding 5 square meters, as well as unauthorised enclosed structures on private roof terraces or patios. The reports typically come from residents, management corporations, or periodic structural inspections.
About 90% of the suspected cases have proven to be unauthorized works, and enforcement action has been initiated in several cases. URA states that they will continue taking action against offenders, including legal prosecution if necessary. Unauthorized works can have several implications, such as compromising structural safety, negatively affecting insurance claims, and impacting property financing and equity.
Mezzanine floors and enclosed structures on private terraces can add significant weight to a building's structural components, potentially jeopardising safety. Insurance companies may not cover losses or damages caused by unauthorised works, and property owners may face increased fees and contributions due to the added floor area.
Additionally, unauthorised works can create disparities among owners, as those who follow the rules may have to bear a higher financial burden.
To address these concerns, unit owners are required to seek approvals or advice from the MCST, government agencies, and a qualified person, such as a registered architect or professional engineer, before carrying out any works that increase the gross floor area of a strata unit. If unauthorised works have already been carried out, property owners must remove the structures or obtain necessary approvals to retain them.
Failure to comply may result in further enforcement action under the Planning Act and Building Control Act, with fines of up to $200,000 and potential imprisonment for individuals found responsible.
