Richard Koenig of Housing Opportunity Development Corp spoke to the morning group about the daunting task of building affordable housing on the North Shore. He showed photos of some recently built, affordable and very attractive, apartment buildings in Wilmette, Glenview, Highland park and other locations. It can take 4-6 years for a building to finally be constructed from concept to reality.  Many zoning regulations must be met and every step of the process is overseen by the local governments. There is always a long waiting list for tenants once a building is available to rent.
