to expand your franchise into your neighbor's neighborhood, look
for a neighbor that has an empty lot. Click on the lot and select
the business you'd like to build. Back in your neighborhood you
will have a head quarters located in your inventory. Place the
building in your neighborhood and construct the building. You use
the building to supply your franchises with goods. The bigger the
franchise, the more floors you can add. You can have more than one
franchise, but you cannot put the same type of business in the same
neighborhood.
