My city will be amending our zoning ordinance to provide for stricter standards for infill development in our older residential districts. Currently these districts allow two family residential by right, with no restrictions other than lot size and area. Duplexes could be located on any lot and you could have an area that is entirely single family with uncompatible duplexes. We have been having problems with infill duplexes, such as not fitting the context of the surrounding development (e.g. side by side duplexes in area where 2 story homes are predominant, no windows on sides of the home, front doors on the side, etc.).
We are addressing some of these issues by compatibility requirements (for both single-family and two-family). Based on other ordinances, we are also considering requiring duplexes to be built on corner lots and each unit entrance to be located on each of the streets. This will limit the number of duplexes that could be built and give the appearance of single family homes from each of the streets. Does anyone else require stricter standards for duplexes, and if so, what?
Thanks for your input.
