Should be ADA-friendly apartment numbering mounted on the wall in the corridor outside the unit. Should have braille lettering in addition to visual numbers. Should be minimal, clean, industrial with no exposed fasteners. Flush mount okay but provide information about installation in fire-rated sleeve. No wiring, no electricity, no operation. Aesthetic is copper, matte black, distressed/blackened bronze, stones, high-aggregate concrete, zinc and leather. Industrial-type aesthetic is okay.
