This is actually something that my father did successfully. It was easy. He just went to a home improvement store and found all the necessary pipe fittings to convert the hose(s) to the house Plumbing pipe(s) he was going to tie into, and found an outlet that was hidden(if you don't have an outlet, maybe you could conceal a heavy extension cord from someplace close), and he parked it in place, and built in the cabinet around it.
NO, definitely not so. I have changed hundreds of dishwashers and never found a case like that.
If the faucet on the sink.can hook up to the dishwasher then yes it can.
If you install a built in the landlord will ask you to leave it or replace the cabinets it replaced. Portable sounds a better deal to me.
Whirlpool 24 in. DU1100XTP Built-in from www.ajmadison.com is a dishwasher that is easy to install.
Possibly if the housing is big enough.
Fitting for WHAT.
The attachments for portable dishwashers are not universal, and do not fit all faucets. To fix this, a person can buy an attachment for their faucet the matches the dishwasher.
Get an adaptor
The majority of weights at weigh stations are permanently installed in the pavement. They are below the asphalt, and not portable at all.
Anything is possible but I doubt it for under $400. It is far easier to go the other way and convert from portable with a manufacturers kit.
Pour a cup of bleach in bottom and run it empty.
