Assuming, you can climb stairs without great difficulty, shouldn't really need to do anything. Maybe look at where a strong handhold could be installed.
If stairs are problematic, you might consider a travel trailer. Preferably one that is low to the ground to minimize stairs.
If it's really bad and you incorporate a motorized scooter into your daily routine, you could consider a toy hauler (assumes you have someone who can open the loading door for you). Then you can just ride the scooter in and out minimizing the stairs.
