I'm surprised that you don't find them. It is the rare HUD Code house that I do that I can't find that manufacturers label. You do have to get aggressive and go into closets, push clothes around and sometimes just feel the wall with your hands. I'll bet in the past 20 HUD Codes that I've done, only 1 or 2 were missing and one particular that I remember was an older one that had all new cabinets put in. Surprisingly enough, when I told them that I could not verify that it was a HUD Code (new siding had been put on), the owner remembered where the old cabinets were, went there, found the label and supplied a HUD number that they were able to get a letter from the manufacturer as to certification, DOM etc.
Most of the time the label is in one of the two small bedroom closets. If it is not there then the next most popular place is inside one of the kitchen cabinet doors. Least likely but the first place I look is the inside of the electrical service covering door.
If the HUD Label is on the house but no manufacturers label inside, I so state in my report. If certification is required from the manufacturer, that is the homeowner’s responsibility to get and provide, just like a legal description. Normally, I do not have anybody come back insisting on the DOM etc. I shoot a picture of each label and include it in the report.
BTW, have a restful 4th. We are supposed to have a glorious day; temp about 80 with full sunshine and low humidity. That after several days in the low to mid 90’s with heat indexes of 100 to 105. We are just not used to that. Came through Onaway the other day and the temp sign said 96! I stopped and checked my map just to make sure I had not taken a wrong turn and somehow ended up in Texas.
Anyway, enjoy the day.
