Weep holes are seldom done in residential construction in my experience. I have never seen a code requiring them(could be though). While they are recommended in commercial construction, they are part of a drainage system of through wall flashing & often a mortar baffle that helps keep the weep holes clear of mortar. The flashing intercepts any water & directs it to the weeps. I would not add weep holes to a wall not designed for them. I doubt if they would work & would more likely cause trouble or damage. If their are no water issues at this point their most likely won't be.

Thanks for the support everyone. I truly appreciate it. If I provide a bit more backround perhaps it will answer some of the questions that have been raised. My parents built their retirement home on a lake in central Ohio 23 yrs ago. They still enjoy the home, but my Dad feels the maintenance has become too much for him and periodically tells my mother (not me) they should sell. The last couple of years she told him she wasn't ready yet - she likes being near family. For the past 12 years they have been spending 6 mos. out of the year in a mobile home in FL. They have a lot of good friends there and it's particularly good for my Dad because he has buddies he hangs out with. Buddies who will ask him to come along if they run errands. In Ohio he has friends, but not the kind who want to hang out, so he's mostly in front of the tv during his waking hours. Going into town to run errands every day was his break, his entertainment so to speak, and now he can't do that. My mother's sister lives on the opposite coast of FL from where my parents winter. She has friends in a retirement community in central FL and has wanted to move there for a few years now. Her husband passed last July, and since she has been more avid to move. Since neither of my parents want to spend winters in Ohio, they are thinking of selling the lake house and buying into the development where Mom's sister wants to live. My mom's sister is 79 and has been undergoing cancer treatments for a number of years. One thing gets cleared, then something else pops up. She is doing okay - as in she's not feeling terrible - but from what I get from my mom the treatments continue. My fear is that if my parents sell the lake house, put all the proceeds into buying new home in the FL retirement community it could be only a matter of a few years until my mom is there by herself. I HATE thinking like that, but given my father's and my aunt's health issues it is a real possibility. I don't believe my mother would want to live there without any family around, so I would probably end up moving her back to Ohio to live with me. A better plan- to me -is for them to sell the lake house, buy an Ohio home closer to town for the 6 months they spend here and keep the trailer for winters since that is where Dad is happy. I've suggested this to Mom and that's when she told me she would never buy another house in Ohio. I'm not sure why she is so adamant. Last summer during our 30 min commutes back and forth to town I would point out areas on the outskirts and say "It's pretty out here and not too far from town." Once she shot back: "Why would I want to live where there wasn't a lake?" I replied, "Um...because you'd have something nicer to look at than your neighbor's windows? Which is what you would have with a house in FL." Maybe she sees buying a house in OH without a lake as "coming down in the world"? Or she feels buying another house here means eventually having to live here during the winter? Maybe she wants to be nearer her sister while she has her? I don't know. I agree the track I need to build for myself is a way to support myself in my own small place. Let mom and dad do what they want to do and cross the bridge of taking care of one or both of them when the time comes. I suppose I'm just trying to prepare myself psychologically for that future. Thanks again Lavender and all, for letting me explore that here.

There's a lot in your message that may be areas for concern. First, the main panel is a Federal, which is notorious for causing fires. Secondly, the breakers in this panel should be double-pole, instead of the single pole that you describe. 30amp fuses in the mobile home are scary, since it's unlikely that the internal wiring is heavy enough to carry this amount of current. Wires coming up through PVC that are taped off, but live, are very scary. My strong recommendation is that you have a professional electrician look at this. This type of job is over the head of most DIYers.

Now that I think about it, the 90° angles I indicated are obvious… It’s really the fact that that middle column is twisted such that it is directly opposite one column but on the other side, the edge of the column is facing into the wall space, or what will be the walls. Hard to explain it! Hope the picture helps.
