The Royal Green Owners Condominium Association (RWA) representing residents of the existing development has filed a formal objection with the Department of Town and Country Planning (DTCP) and other authorities over the occupation certificate (OC) for a newly completed tower. The association has asked for a joint physical inspection to verify whether the tower has adequate infrastructure and whether its occupation could place additional pressure on facilities already used by existing residents. The objection was filed within the prescribed 30-day period and seeks independent verification of sanctioned and as-built records.

One of the RWA's primary concerns is sewerage capacity and the connection to a sewage treatment plant (STP) or public sewerage network. The association has requested inspection of the complete sewerage chain to confirm whether available capacity suffices for the 276-unit tower and has highlighted the potential effect on sanitation and everyday maintenance if capacity is inadequate. Parking availability is also under scrutiny after the association calculated one point five equivalent car spaces (ECS) per dwelling unit and concluded that 414 ECS would be required; it has asked authorities to identify and verify those spaces on the ground.

The residents' body has urged Fire and Emergency Services to conduct an actual fire-tender movement test because of a sharp turn on the approach road and possible obstructions affecting access. The inspection would assess road width turning radius load-bearing capacity and access to designated firefighting positions to ensure emergency movement is feasible. The association has called for a colony-wide green-area audit after alleging that some areas originally designated as open space may have been covered or used for parking and it has sought confirmation that common facilities serving existing residents were not counted towards the new tower. The developer has disputed the concerns and said the project followed approved building plans noting the units were sold between 2011 and 2014 and constructed in 2017 with the current management completing remaining works and obtaining the OC from DTCP in August 2026.

Authorities must decide on the joint inspection. Buyers will watch developments closely.
