Zoning - Minimum Housing Standards r CITY OF ROSEMOUNT EXECUTIVE SUMMARY FOR DISCUSSION COMMITTEE OF THE WHOLE DATE: September 22, 1997 AGENDA ITEM: Housin Zonin Standard Enhancements AGENDA NO. g g � . ITE�� # � � PREPARED BY: Rick Pearson, City Planner ATTACHMENTS: Current Standards and comparison with other cities. / Planning Staff have been discussing potential enhancements to the housing standards in the zoning ordinance. The issue originated with an internal discussion of the minimum single family requirements expected of the approved Hampton concept compared with the subsequent proposal that was approved. The need for enhancements to R-2,R-3 and R-4 districts is also apparent in light of the Town& Country project review process. The focus of the enhancements includes dwelling unit finished square footage minimums for living space and, explicit garage and storage requirements. Other standards may include private recreational amenities, linked open I green space beyond the usual setback requirements and increased landscaping. A comparison of other cities standards is being assembled for discussion. Inver Grove Heights, for example has a very sophisticated series of standards for town houses that may provide useful examples. Outside forces such as "Livable Communities" and market pressure will continue to influence development proposals. Standards can also control the ratio of units that might have affordable features such as single car garages for example. Buildings without basements may actually be desirable due to certain conditions such as a high water table or irrelevant for a disabled homeowner. In addition,the building industry is providing homebuilders more options that meet higher design standards such as metal roofs.
