04:02.24 Zoning Petition - Expianation of Changes Principles and Approach: - Change standards in current districts, rather than a complete rezoning to better understand impacis on existing areas. - Aim for substantial but incremental changes, rather than wholesale changes, because development standards interact with other forces (market forces, affordable housing overlay) that affect affordable housing production and it is important to retain a benefit for affordable housing development. - Advance a zoning change soon while taking time to consider more wholesate changes down the road. Based on the recommendations by the Planning Board and CDD in 2022, setbacks will need more study and discussion, especially in terms of their effect on benefiting AHO development. - Zoning changes are not the only way to affect affordability and incremental zoning changes like these will allow CDD to bettor understand changes in affordability over time. This petition seeks to deliver substantive zoning relief for multi-family development while retaining specific measures that incentivize affordable housing production via the AHO pathway. Articie 4.000 Use Reguiations 4.20 Special Classification Rules - Eliminate footnote (i) under 4.21 to eliminate the prohibition of accessory dwelling units outside of Industrial Districts. - Eüminate footnote (i) under 4.2i to allow more existing accessory buiidings to be converted to residential uses. - Eliminate unnecessary requirements for special permit for accessory apartment development under 4.22.1 in order to streamline process. Future intent would be to allow a path for as-of-right accessory apartment development in line with existing dimensional regulations. Intent: to ease development process for Accessory Dwelling Units 4.30 Table of Use Regulations Modify the Table of Uses to allow all residential uses in all residential districts. Eliminate footnotes (2), (15), and (17), which prohibit exterior changes in Res A districts. - Eliminate footnote (5) from Res A, B, and C standards to eliminate Planning Board requirement for multifamily residential uses within residential districts. Primary Intent: to allow multifamily residential uses across the city. Secondary intent: to eliminate footnotes that further restrict residentiai development within fuily residential districts and to bring Res A and B uses in line with existing Res C uses, making multifamily uses both permissible and feasible.

04:02.24 Zoning Petition - Expianation of Changes Article 5.000 Development Standards 5.30 District Dimensional Regulations - Modify the Tabie of Dimensional Requirements - Residential Districts (Tabie 5-i) to: • Increase FAR to 1.0 for Res. A-1, A-2, B, C, C-1 to allow density required for multifamily development. • Decrease the minimum lot size in Res A-1, A-2 to 5,000 sqft, in line with Res B and C standards. • Decrease the minimum iot area for each dwelling unit in Res. A-T, A-2, B, C, C-1 to 1000 sqft, in line with Res. C-1A to allow for more density and flexibility for housing development. This would bring a lot of existing C-1 zoning into conformity as well. Decrease the minimum lot width in Res A-1, A-2 to 50 feet, in line with Res B and C standards. • Eliminate footnote (i) which distinguishes the dimensional differences between Res. C and Res. C-1, which would now be essentially standardized. • Eliminate footnote (i) which unnecessarily restricts FAR and minimum lot area for lots larger than 5000 sqft in Res B districts. - Modify the Table of Dimensional Requirements - Business Districts (Table 5-3) to: • Increase FAR to 1.0 for Bus. A-3, and to reduce the minimum lot area for each dwelling unit to 1000 sqft, in line with Res. C-1 as they are essentially the same zoning district. Article 9,000 Nonconfermity 9.20 Nonconformance - Amend footnote (c) that unnecessarily limits construction on nonconforming structures that is already occurring entirely within the structure to more closely conform with state law MCL Chapter 40A, Section 3. - Eliminate the rules that limit new additions to a small percentage of the existing area or volume within oinerwise conforming additions. • 8.22.1 (f) eliminate the area or volume limit of 10% • 8.22.2 (c) eliminate the area or volume limit of 25% ürner considerations not incided: Minimum Yard Setback Requirements - We considered adjusting minimum yard setback requirements in Res A and B districts but determined to retain setbacks for two reasons: one was at the discretion of the Planning Board recommendations in 2022 and the other was to continue to give AHO projects a competitive advantage over market rate development. Minimum Ratio of Private Open Space to Lot Area - We considered reducing the minimum ratio of private open space to lot area to 30%, in line with kes. C-T standaras, but erred on the side or caution, given climate resitience concerns as well as affordability concerns, given the AHO development advantage.

4/2/2024 ARTICLE 4.000 USE REGULATIONS 4.20 SPECIAL CLASSIFICATION RULES 4.21 Accessory Uses. j: Ne accessory building shall be used as a dwelling except in an Industrial District for the accommedation of a night watchman or janitor. i: No accessory building may be cenverted to-a-residential use unless it conforms with the district dimensional regulations specified in Section 5.30. 4.22 Accessory Apartments. The purpose of this Subsection 4.22 is to allow for the creation of accessory apartments in all districts. Many large existing single and two-family dwellings or other accessory buildings on their iots are underutilized: Aiteration of these buidings to provide one additional dweiling unit on the iot would be prohibited in most cases due to the existing floor area ratio and/or lot area per dwelling unit requirements of Subsection 5.31, among other zoning limitations. Given contemporary lifestyles, housing needs, and energy and maintenance costs, it is beneficial to the City to allow greater flexibility in the use of such buildinge to add new dwelling units without substantially altering the environmental quality of their surrounding neighborhoods. This Subsection 4.22 gives the Board of Zoning Appeal the authority to relax such requirements in certain instances as enumerated below. 4.22.1In all districts the Board of Zoning Appeal may grant a special permit for the alteration of an existing single- family detached dwelling, two-family dwelling, or accessory building on the same lot as a single-family or two-family dwelling to provide one accessory apartment if the following conditions are met: The building containi ing the accessory apartment has been in existence since on er before February 1; 1. 2019. In the-case of an accessery apartment wit ingle family or twe family dwelling, prier-to-alteration 2. the dwelling contains at least one theusand ei ht hundred (1800) square feet of gress fleer area: In the case of an accessory apartment within a-single family or two family dwelling, such accessory 3. apartment shall not occupy more than 900 square feet or thirty-five (35) percent of the gress fleer area of the principal dwelling, whichever is less. An accessory apartment created -an accessory building shall not occupy more than 900 square feet: 4. No more than one accessory apartment shall he allowed on any lot. Page 1 of 5
