Tenant Parking at a duplex

[Josh Pryor]

I have an inherited tenant with a small issue. The garage does not come with their unit. There are 2 parking spots in front of garage door, and 2 on side of house. They constantly park in front of the garage. Both spots in front of the garage door are taken. I’m left without using the garage. This is my first time dealing with this stuff. Can I write a letter that gives us assigned spots? Should I have them sign it? I thought I could include a gift card for a local eatery and a note that states that moving forward, unit A parks here, unit B parks here, so they can use their garage. Make sense? I’m looking for a peaceful resolution.
