Hi guys, I have a question. I did a home inspection today, the water heater was in the laundry room. The room was just off of the kitchen. The house is on a slab. I thought if a water heater is installed in a living space that it had to have a pan under it with a drain line. The agent call someone and they told her if the floor is concrete and not wood, you don’t have to have one. The floor is tile. I told the buyer that I would check with you all on how I should write it up. But I told her I would want to have one because if it goes out when shes at work or out of town, she is going to have a mess.

Listed pans shall comply with CSA LC3.
It also goes on to say the pan will be drained by an indirect waste pipe having a minimum diameter of 3/4". I always write up 2nd floor or attic water heaters that do not have pans or have damaged pans. It’s a judgment call on 1st floor heaters, i.e. is there really a risk of collateral damage from a leak? If so, then write it up. BTW, the 2003 IRC may or may not be applicable to your area. You need to know what your state/AHJ has adopted.
