Disclaimer & Purpose

This is not an official document; this document is not endorsed by the Grand Rapids Planning Commission, 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 late May, 2024. 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.

Shelterforce ADU Series

Shelterforce recently developed a six part series on ADUs (Accessory Dwelling Units). While there is currently no hope of meaningful zoning reform in Grand Rapids, MI I believe this remains a critical topic to track as ADUs should be the clearest path for residents to invest in their own neighborhoods - right on their own property.

ADU Convening

In October of 2020 Invest Health hosted a "convening" related to ADUs. The invited communities were Grand Rapids (MI), Missoiula (MT), Napa (CA), and Riverside (CA). The convenings were held for two hours over five days. The media and video of the convening are now available. Of particular interest is the financing options portion of day #2; local expertise in this area is extremely limited.

The first part of this article is a narrative in response to the surprising number of questions I received regarding “Why?”. Anyone interested only in the process and numbers can scroll straight down to “The Granny Flat Alternative”.

UPDATE: 2019-09 - It appears that the new status-quo is what is, the disappointing results of "Housing NOW" are what we have for the foreseeable future.

A Critique of NOW's ADU Proposal

It has been more than six months since the Housing NOW related zoning proposals were released, and then indefinitely tabled. I have yet to encounter a detailed critique of the proposals. Given the disappointing condition of the debate I've decided to offer one here for the topic of which I am most familiar: Accessory Dwelling Units [ADUs]. Are there problems with is proposal? The answer is "yes".

ADU Regulation Reform

The Grand Rapids Planning Commission is hosting a community discussion about possible changes to the zoning code related to Accessory Dwelling Units (aka: ADUs). This conversation is the result of a report of possible policy changes created by the Housing Advisory Committee.
