This is how our residential front yard setback ordinance reads:
(b) Front Yard. There shall be a front yard of not less than thirty feet, provided that if forty percent or more of all the frontage on one side of a street between two intersecting streets has been developed with one-family houses, the front yard so established shall prevail. This section shall not be construed to permit any new house to be closer than twenty feet to the front lot line, or require a front yard setback of more than fifty feet from the front lot line.
OK, so in a lot of the older neighborhoods with houses at 20 feet, this means that the established front yard setback (20') will be what we go by, as opposed to the 30 feet.
What about in a new neighborhood where all of the houses are setback 40 feet. Does this mean any new infill (or a front addition) has to be set back at 40 feet, or can it go with a 30 ft setback?
I'm thinking literal interpretation says yes it has to be at the 40 foot, but criminy, this stuff tends to make you go in circles if you look at it too often.
