How do you handle parking at your multi family houses?

[Tyler Brown]

This isn't a situation I have at either of my current properties, but I'm looking to purchase a two family home, and I'm seeing some on the market that have a driveway that is only wide enough for one car.  While it may be long enough to fit several vehicles, the vehicle in front would have to be moved to get any vehicles behind it out.

If you have a property like this, how do you handle it?  Does your lease give the whole driveway to one unit, and instruct the other to park on the street?  All other things being equal, I assume you would charge a premium for the one with driveway access?  If one unit is a 3 bedroom, and one is a 2 bedroom, would you give the larger unit the driveway by default?  Would you not address it at all, and just tell the tenants to work it out amongst themselves?
