Most Macau fit-out disputes start with something already in the building: a gate in the corridor, a leak from above, a pump room nobody measured. Three developments in the past two months make these worth checking before a quotation is signed, because each changes who pays and when work may legally start.
1. Common parts: the October enforcement drive
On 31 October 2026 the Government Information Bureau reported over 200 units across three blocks of a Ilha Verde estate with metal gates occupying common corridors. After DSSCU processed the cases in batches and issued notices, most owners removed the gates or repositioned them lawfully; only a few did not comply. Offenders face a fine plus the cost of government demolition. An earlier government release on a similar case recorded four blocks, about 500 units, roughly one tenth uncooperative, and fines of not less than MOP 10,000.
The bureau uses aerial photography for inspection and issues demolition orders in batches, prioritising new, renovated or dilapidated buildings and those issued an occupation permit after the Urban Building Legal Regime took effect. The amended Regime simplifies demolition: lower-risk illegal works may skip prior notification, provided the owner notifies the bureau in writing afterwards for archiving; voluntary demolition qualifies for incentive reductions. DSSCU guidance also calls for a full inspection or repair of common parts at least once every five years.
What a tenant should ask first
Before signing a shop or office lease, compare the property registration report and building rules with the actual partitions, gates, air-conditioning positions and service points. If a previous occupant left unauthorised work, the demolition order and downtime can fall inside your lease. State in the lease who pays for reinstatement.
2. The prior notification route is narrower than it looks
DSSCU's renovation guidance allows a light route for non-residential units of usable area up to 120 square metres, where work changes neither use, area nor structure and does not affect fire safety systems. A Prior Notification of Non-Residential Alteration, Maintenance and Repair Works needs no project technician, no works permit and no tax. Once accepted, the stamped form displayed at the site is proof of acceptance.
The notification names the applicant, site, expected start and completion dates, a description of the work, and the contractor registered with DSSCU. Attach its declaration of responsibility, labour insurance and the property registration report; a tenant adds the lease and the owner's written consent. Complete files draw a reply in about 10 working days. Works on common parts need a separate notification, approved by a majority of the owners' meeting representing at least 15 per cent of the building's total value.
Quiet hours apply. Under DSSCU guidance and Law No. 8/2014 on environmental noise, noisy alteration, maintenance and repair work in residential buildings is barred all day on Sundays and public holidays and from 7pm to 9am on weekdays. The law also covers air-conditioning and ventilation equipment and activities in commercial units.
3. Leaks: establish the source before you price the repair
The government portal's seepage service page, updated 25 September 2026, describes a one-stop Interdepartmental Centre for Handling Water Seepage in Buildings, coordinated by the Housing Bureau with DSSCU, the Municipal Affairs, Health and Legal Affairs Bureaus. Cases may open for strata-titled residential, commercial-residential or industrial buildings where an approved water supply and drainage system is blocked or leaking, and an initial check by a repair technician has not found the cause.
The centre first encourages negotiation, then uses non-destructive instruments to locate the source and issues a detection report identifying the responsible party or recommending measures. Contact the Housing Bureau on 2859 4875 or CITIA@ihm.gov.mo. Citing official 2026 statistics, legislator Lei Cheng I noted 1,249 cases completed from January to early August and about 5 per cent still unresolved; she also flagged privately commissioned reports that were not accepted, and the compulsory arbitration regime for seepage disputes, in force nearly three years. DSSCU publishes a list of qualified entities providing seepage detection reports.
Why kitchens and cold rooms suffer most
In a restaurant kitchen, cold room or freezer, seepage through a floor slab repeatedly damages waterproofing, insulation and refrigeration plant. A written finding on whether the source is a common pipe or an upstairs unit decides whether all owners share the cost or one pays. Without it, new waterproofing is laid over an unresolved cause.
4. Pump noise: a measurement guideline has arrived
At a 23 October 2026 industry briefing for about 150 sector representatives, DSSCU explained the Urban Building Legal Regime, the revised Water Supply and Drainage Technical Regulations, the gas appliance exhaust duct design guideline and its paper-authorisation e-archiving service. The Environmental Protection Bureau introduced the Guideline for Acoustic Measurement and Report Preparation for Building Pumping and Pressurisation Facilities (Macao Daily News, 23 October 2026).
This matters whenever a water pump, pressurisation set, lift pump, air-conditioning or ventilation unit is replaced or added. Law No. 8/2014 already covers air-conditioning and ventilation equipment and activities in commercial units; the bureau's 2025 noise monitoring report records six stations measuring continuously, with day 8am to 8pm and night 8pm to 8am. Name the acoustic measurement and report in the tender, not after a complaint.
5. Five questions to put in the tender
- Is there unauthorised work in the unit or common part? Who reinstates it, and does the programme allow time for a demolition order?
- Does the work fit the 120-square-metre prior notification route? If not, who prepares the project and obtains the works permit?
- Is there a written seepage detection report? Is the source a common pipe or another unit, and who pays?
- Will pumping or ventilation plant need an acoustic measurement report? How will works avoid the statutory quiet hours?
- Is the contractor registered with DSSCU? Are the declaration of responsibility, labour insurance, property registration report and, for tenants, the owner's consent attached?
Prof Team Engineering Co., Ltd. is registered with DSSCU for the execution of works (Registration No. 7003/2024, Certificate No. 1648/DIP/2025), covering renovation, MEP, kitchen, air-conditioning and environmental construction. These checks belong in the tender before a price is agreed — not on site afterwards.
