What is a Lot Restriction?

Lot restrictions are imposed by municipalities to control the development of property within their borders. Developers must comply with these restrictions, which cover aspects like minimum lot width, minimum lot area, maximum lot coverage (i.e. how much of the lot your building can cover), setbacks, height restrictions, impervious structures, off-street parking and the number of buildings on a lot:

  • Impervious structures are artificial structures such as driveways and sidewalks that are covered by impenetrable materials like asphalt, concrete, brick and stone. Municipalities restrict the percentage of a lot’s impervious surface area to reduce environmental damage. If the minimum impervious rate is 70%, that means the maximum impervious surface area of a 10,000 ft2 lot is 7,000 ft2.
  • Setbacksare imposed by municipalities to indicate how far a property must be from a boundary line or adjacent properties. In other words, you can’t build your home too near the street or your neighbor’s house. How near or far is determined by the setback.
  • Maximum height restrictionsrefer to the maximum height in feet of the structure to be built, from the peak of the roof to the lowest grade (ground) at a maximum of five feet from the perimeter of house.
