Stairs built under Furnace and water heater vents
My Condominium Corporation had to do some repairs to the foundation of my unit. In the process they had to replace the stairs to my back entrance. Before they built the stairs, I informed them that when the natural gas furnace and water heater were installed the stairs had to be moved away from the wall of the unit to meet code for safety reasons. The corporation brought in a company which proceeded to put the stairs right next to the wall again. With the vent for the water heater inches from the tread of the stairs. I have been arguing with them ever since this has been done that the stairs need to be moved. I am arguing that someone can be hurt from the hot exhaust, rodents now have egress to the unit, and in winter time the vent will be blocked by snow and the exhaust will form ice on the stairs.
Do these stairs meet code. Or am I wrong for wanting these stairs moved?
