1. Building Facade Signage Ratios & Dimensions
On-premise commercial identification signs mounted on building facades or entry arcades are regulated based on building front elevation area:
- Maximum 15% Facade Area Cap: The total cumulative surface area of all wall-mounted signage on any building elevation must not exceed 15% of the total ground floor facade area (or maximum 60 square meters, whichever is less).
- Vertical Elevation Limits: Wall-mounted tenant signs must not extend above the roof parapet level or overhang public footpaths by more than 0.60 meters (600mm).
- Clear Clearance Height: Signage mounted over pedestrian walkways or retail arcades must maintain a minimum vertical head clearance of at least 2.75 meters from the ground surface.
2. Digital LED Billboards & Luminance Caps
Electronic digital billboards and illuminated display screens are subject to strict photometrical controls to prevent glare hazards:
- Maximum Daytime Luminance (5,000 Nits): Outdoor digital LED billboards must not exceed a maximum brightness of 5,000 nits ($\text{cd/m}^2$) during daylight hours.
- Automatic Nighttime Dimming (500 Nits): Between dusk and dawn, digital screens must automatically dim to a maximum luminance of 500 nits via ambient light sensors.
- Prohibition of Flashing / Motion Video near Junctions: Full-motion video displays and rapid flashing animations are strictly prohibited on billboards situated within 100 meters of any signalized road intersection or expressway exit ramp.
