Would it make sense to look at percentage vs. number of hazards? So, for each resident, the outcome would be the percentage of possible hazards they experienced, which might circumvent the number of rooms issue.

Subject: How to code hazards across house rooms
Dear List: I have just received an SPSS data file from a colleague that contains responses from a City’s elderly residents who reported on safety hazards within their homes/apartments. Each room could have anywhere from 10 to 14 hazards
that the residents had to check off. We are interested in getting a total hazards score for the five rooms (across the kitchen, living room, bedroom, dining room, and bathroom). However, I have noticed that not all of the residents had five rooms. Some lived
in efficiency apartments and only had two rooms. If I totaled up the number of hazards across all rooms those with fewer rooms would automatically have lower hazards. If I obtained the mean across all of the rooms than residents could have the same mean number
of hazards but it would be based upon a different number of rooms. I am trying to figure out how to factor in the number of rooms. Some way of weighting the scores but I am a bit dumbfounded on this. I realize that this is not an SPSS question but would appreciate
suggestions (if you would like to chime in) as I begin to figure out how to analyze the data. Thanks in advance, martin
