You could if you wanted put in one of those motorized chairs that you sit in and it takes them up the stairs.The rail might have to be beefed up or changed to handle that kind of weight versus just putting a hand on the rail.When people get that age generally they do not want to move at all.

The owner is responsible to purchase specific beds, chairs, desks, TV's, etc.

If raised beds are required, I can help them with that (I've helped a local senior residence build raised beds so residents in wheel chairs can garden).Water will not be an issue, I can place a rain barrel on-site.I run the idea of a "release from liability" past Council, but it's not as pressing a concern up here ... fortunately we are still a less litigious society.The gardening season here is only 4-months and our participation will only be committed for the current season, so if it doesn't work out, we'll not do it next year.

My knee won't tolerate the time standing behind the chair.

So no certain value and portfolio is unsellable.5) Inability of banks to service portfolio payments means they lock up and stop issuing loans6) Music stops and no more chairs, people realize they bought at top of the market and better to just walk on the property.Now that Biden's talking like 2) (people need $15K tax credit to be a first-time buyer even if they can't afford a place) and price have inflated and we still have CMBS, seems almost prophetic. 

I bought 300 tables and chairs and two massive tents and a dance floor.  

One is a ~2200 sq ft pizza shop open 7 days a week, and the other is a 400 sq ft single chair barber shop open sporadic hours a few days a week.

If a tenant in a wheel chair needed a ramp installed to access an office to pay rent, you’d install a ramp.Im not sure how the SRO is but I imagine it’s much worse than individual apartments.

The hardware store sells a steel "chair" to set the water heater on, that will meet this requirement.Always get a new temperature and pressure relief valve; don't re-use the one from the old heater. 

Also I would put in 2 folding tables and a few chairs for people to sit in while waiting.
