It should not get past rough in -- where all is anticipated as locations for install, whether it be a range, shower,laundry, kitchen, or whatever code may require specific electrical installs are for the planned rough in. I see future hottub disconnects all the time, While I cannot stop the install of the branch circuit to a location, I do review with the responsible party circumstances that need to be addressed if & when a hottub is installed. If they install the hottub to close to outlets and have another inspection they may fail. Keep in mind that the future hottub is gennerally just electrical only.
