The majority of residential streets in Cambridge and Somerville are marked Parking by Permit Only, thereby limiting parking to residents of each town.
Please note that these parking restrictions are not in effect on Sundays. This makes it much easier for open house visitors from out of town to park near properties they are visiting.
Many of my buyer clients over the years have preferred to meet me at Hammond Real Estate in Harvard Square so that we can travel together in my car to visit properties of interest. Hammond Real Estate offers free parking (to clients visiting with me at Hammond) at the University Place Parking Garage in Harvard Square.
