Can a person live in a tent until the home is up to APS standards?

That's what hotels/motels are for: temporary residence while work is being performed inside one's permanent residence. Or a friend's home or a relative's home or or OR some place with a TOILET. Anything BUT a tent, for petesake! Not to mention, how was this person with COPD able to withstand the living conditions that APS condemned in the first place, if they can't withstand 'work conditions' inside the home while it's being cleaned up?

No. My non expert opinion is that APS will not approve of a vulnerable adult receiving 24/7 care in a tent while their unclean/less clean home’s floor is cleaned and repaired, not even if the tent has access to a hose and extension cord with heater or fans and some kind of toileting facilities.

The description that the floor needs to be cleaned before it can be repaired makes me visualize a hoarding situation.

The part where the work area includes the whole house and that the occupants won’t have access to it during non work hours leads me to believe that money is tight and the work is being done by non professionals and that the house is in unusually bad shape.

The best way to find out what APS will consider appropriate is to ask.

Note that the city or county may also have regulations prohibiting people from living in tents, RVs, etc. for an extended period of time.

Why does the floor need fixing? Who is paying for the repair?
Do you have homeowners insurance or if you rent does the landlord? Homeowners may pay for a hotel stay if it can be proven the person has a health problem. Usually in circumstances like this, plactic sheeting can be put up in the doorways so partials will not escape. Ask that the people doing the work vacuum very well whent they leave.

I also agree to call APS and see if they can help in some way. I just had my Den repainted and the painter did a lot of spackling and sanding. The dust bothered me a little so I can see where someone with breathing problems it would bother.

Zoning restrictions might apply; best to check with the local community government and determine if temporary tent living is allowed.  

I have serious concerns though about anyone  living in a tent other than serious and experienced backpackers.

I have been in many a tent in many a place, and my personal opinion is "no".
If such a thing is contemplated I would get the opinion of APS personnel first.

Whose idea is this? The person needing care, or somebody else?

Common sense says no. And I can't imagine a caregiver having to work in a tent.

Sometimes there is a post in this group that is so outrageous that after I get done wiping the tears of laughter off of my face from reading it, I wonder if it's real or not. Like the one who asked if it's okay for an elder living alone with dementia and mobility issues to crawl around on the floor like an insect to get from one area of the house to another.
This one is even better!
I'm going to assume that it's a real question we have here being asked by a real person looking for some real advice. So, I'm going to help you out and speak as plainly as I can so you understand.

NO! IT IS NOT OKAY!!! A person who has a live-in caregiver CANNOT stay in a tent outside.

I'm going to take some liberty here and assume that the tent you're talking about isn't a M*A*S*H hospital. Or some luxurious setup out in the desert complete with servants, camels, treasure and a beautiful harem girl who tells your loved one exciting stories to keep them entertained while the belly-dancers are resting.

So unless your tent is one of these two kinds, NO! IT IS NOT OKAY!!!

The person with the live-in caregiver can get a respite stay in a care facility paid for by their insurance while the work gets done.
If the damage getting repaired was an accident the homeowner's insurance may pay for a stay in a motel or hotel with a kitchenette, depending on how long the work takes.
An Airbnb could be a possibility like PeggySue has said.
Also, unless you are the live-in caregiver, don't expect the employee to have to share a motel/hotel room with the elder they take care of. A live-in caregiver provides 24 hour care. That does not mean they have to be in the same room with the elder every moment. I'll call that cruel and unusual punishment. I don't think APS would approve of that either.

If a short term hotel/motel is not an option renting an RV might be an option that would be sorta between the choice of a tent and a hotel.
As long as there is running water, electricity, easy access, it is safe and there is a caregiver present if one is needed I would think that it would be acceptable.
But it might be wise to run this pass APS as long as they are involved.
If money is a problem they may put you in contact with services that could help with housing.

Agreeing with PeggySue, a motel or short term rental (airbnb etc) would be more appropriate.

If APS has already been out I don’t see how they could be in a tent. Can the elder and caregiver be moved to a super 8 kitchenette?
