So, in Dallas, the parking requirements for restaurants depend on the amount of seating the restaurant has. A few restaurants got around that by building giant patios with several times the seating as inside, because the regulation doesn't consider outside seating as seating.
Residents complained about people parking on their streets and blocking their driveways, and they threatened massive lawsuits. The city council caved and passed a new regulation counting outdoor seating as seating, with no grandfather clause. Now these restaurants have to either build massive parking garages or close their doors.
