ZONING REFORM Overall Tool Usage The survey was built around one simple question: Which of the tools have you used to increase housing choice and supply in your community? Overall, the average number of tools used by each community was 4.6. Some used as many as 11, while a couple reported having used none.

The chart shows two favorite tools. The first, Text amendments permitting new residential uses in existing districts , took place most often in commercial districts (64 percent), offering synergies between these two use types. But a majority of respondents also reported making changes in their residential districts (55 percent). The next most popular tool was process based: Expanding administrative review (43 percent, vs. longer and more uncertain discretionary approval processes. A complementary form-centered tool was also in the top tier (40 percent): Permitting missing middle housing and accessory dwelling units . Police power ordinances to regulate nuisances that are sometimes addressed through zoning (e.g., parking and noise) were employed by 38 percent of respondents. This process approach takes pressure off housing-specific regulations by using more direct methods to achieve the same result. A more flexible approach to nonconformities was used by 34 percent, another non-housing-specific process that creates overall regulatory relief. The suite of form-based tools aimed at allowing smaller (more affordable), denser (supporting more commerce and amenities), and potentially car-optional residential choices received lower but still significant support. Reducing or eliminating minimum dwelling unit size , including deferring to the statewide building code rather than regulating via zoning, was the most popular at 32 percent. Reducing or eliminating residential parking requirements was used by 27 percent. Twenty-eight percent said they had Reduced or eliminated minimum lot width and area . Additionally, the survey provided an open comment box to answer the question, “What other tools has your community used to increase housing supply and choice?” Responses included new zoning tools, as well as other strategies for supporting land acquisition, leveraging incentive programs, and establishing partnerships with nonprofit housing organizations. One of the tools used least is pre-reviewed plans; The League encourages readers to review our work, “This Used to Be Normal: Pattern Book Homes for 21st Century Michigan.”

The objectives of the Toolkit aim to: • Equip municipal leaders with the tools they need to update and contemporize local zoning and development review regulations to develop more, and a broader range, of housing types; • Highlight successful case studies in Michigan and nationwide that demonstrate the application of recommended strategies to reduce or remove regulatory barriers; • Share master plan language to support the implementation of each tool and demonstrate how to translate a vision into zoning policy; • Create messaging best practices to help everyone— elected leaders, municipal staff, residents, businesses, and other stakeholders—to broaden their understanding of housing needs and potential solutions within Michigan; and • Build the foundation for future work, focusing on housing strategies that can be championed by a broad coalition of stakeholders. This Toolkit is designed to help municipal leaders implement zoning reform to expand housing choice and supply and, in the process, combat the affordability crisis. As a community manager, elected or appointed official, zoning administrator, planner, or other person involved in guiding community change, we hope this Toolkit will be useful to you as you have important (and likely difficult) conversations with your colleagues and constituents on this complex issue. Zoning Survey To measure the efficacy of its toolkit, MAP surveyed both its members and RRC Communities about zoning reform and specifically about awareness and use of the toolkit to inform housing decisions. The survey was built around one simple question: Which of the tools have you used to increase housing choice and supply in your community? MAP heard from 50 cities, seven villages, 58 townships, and four counties. Overall, the average number of tools used by each community was 4.6. Some used as many as 11, while only a couple reported having used none.
