Housing, including apartments, currently exists in the Common district, so that aspect is not new. The Revitalization Roadmap (PDF), p. 71, summarizes housing at full build-out over many years, in every possible space, up to 193 units. Some developers may not want housing, but if they do, the number of units in each development is limited by the parking made available, which must comply with the bylaw. Sections 173-221J and 173-224 of the proposed zoning bylaw (PDF) explain this parking requirement. Housing in the Common is intended to allow a wider range of housing options for folks trying to build life as an adult and folks trying to preserve the life they have built in Littleton.
