Zoning: Accessory Dwelling Units

Status

As of 2018-12-18 this document is obsolete. The City Commission ratified changes to the zoning concerning ADUs on that date. Theoretically there will be another set of changes sometime in March/April/May/... at which point this document is will be updated to reflect whatever that result is.

Briefly, the changes on 2018-12-18 were:

  • Floor area ratio changed to 40% (from 25%). Size now has a hard limit of 850sq/ft. Minimum remains 400sq/ft.
  • Height reduced from 25ft to 20ft, except in some extremely rare cases.
  • Minimum lot area of 5,000sq/ft removed, now lots only need to be conforming to the minimum lot size of the zone.
  • Confusion between ADU size and Accessory Structure size has been resolved; and ADU doubles the sq/ft allowed in the Accessory Structure.
  • No change to permitting process.
  • No change to Owner Occupancy or Deed Restriction requirement.
  • No change to unit (1), occupancy (2), or bedroom (2) limit.

Disclaimer & Purpose

This is not an official document; this document is not endorsed by the Grand Rapids Planning Commision, nor are its authors qualified to present legal opinions.

The purpose of this document is to provide an introduction to the regulations related to Accessory Dwelling Units in the city of Grand Rapids, MI as of 2018. Within the Zoning the topic of Accessory Dwelling Units are directly addressed in section [5.9.03]. Other sections of the code may still impact the development of ADUs so we have attempted to cross-reference the most relevant sections.

DASH 3.0

Still slated for launch on August 27th.

This map illustrates what Downtown will look like when the DASH 3.0 is launched, including the enhanced RAPID#19 Michigan Crosstown as well as the LakerLine. Construction of the LakerLine begins later this year with service commencing in 2020. The combination of these route changes create a far more effective mesh of transit service for downtown.

EV Charging Stations

Electric charging stations where installed in 2011.

  • 5 downtown (1 on-street)
  • 1 in Oak Industrial Park
  • 1 at Waste Water site.

All stations have been upgraded; new stations have two cords and have retaining clips to help keep the cords off the ground which was an issue with the previous charging stations.

Voter Support Of the RAPID in 2017

RAPID Support By Precinct, 2017

This is a map of voter's support of RAPID funding in November 2017. Creation of this map was inspired by the "Transit Supporter Split" BLOG post. That post, at least proposed, that in the city of Portland [Oregon] that transit support had a conical shape: strongest downtown, tapering down as one moved out through the neighborhoods, and zeroing out into opposition when one reached the true suburbs. It raised the question of what support for the RAPID looks like in Grand Rapids.
