Basement Apartment Rentsal

[Benjamin Ford]

I currently live in Falls Church, Virginia (Fairfax County) and am thinking about converting my basement into an apartment and renting it out. I think there may be Fairfax county rules against this, but I am wondering if anyone has an idea of how loosely/strictly those rules are enforced. Along the same lines, I know the county recently passed some laws that permit Airbnb and other short term rentals for a limited number (60) of days per year. I was wondering if anyone had an idea of how strictly that ordinance is enforced as well. 

Thanks,

Ben
