Title

An Ordinance to Amend Section 5:1(1), 5:10.2, 5:10.4, 5:10.5 and 5:10.10 of Chapter 55 (Zoning Ordinance) of Title V of the Code of the City of Ann Arbor (Accessory Dwelling Units) (Ordinance No. ORD-16-16)

Memorandum

On April 19, the Planning Commission recommended approval of zoning text amendments related to Accessory Dwelling Units (ADUs).  The Environmental Commission passed a resolution supporting proposed changes on March 24, 2016 and the Housing and Human Services Board passed a similar resolution on May 12, 2016.

City Council held a work session on May 9th as ADUs are one of the council priorities for 2016.  At the work session City Council considered the matter.  The discussion led to a few changes to the text amendment. The update has a date of 5/24/16.

Description and analysis

 

Chapter 55 (Zoning), Section 5:1 (Definitions) - In this section, Accessory Apartment will be renamed Accessory Dwelling Unit, and ADUs can be allowed in accessory structures.  Occupancy standards are removed in the definition as they are addressed in the text of Section 5:10.2.

 

Chapter 55 (Zoning), Section 5:10 (R1A, R1B, R1C, R1D, R1E, single family district)

A purpose statement was added.  Proposed amendments allowing ADUs in R2A, but only on parcels with a single family dwelling unit; and exclude parcels that have a duplex.

 

Owner-occupancy is required in either the primary or accessory dwelling unit.  While an absence is allowed, it cannot exceed 6 months in a calendar year.  The owner may live in either the ADU or the principal unit. 

 

As proposed, ADUs can be developed as part of the primary unit (basement, attic, addition), or as a detached accessory structure. Legal, conforming accessory structures built before Dec. 31, 2016 can include an ADU.  In addition, existing legal accessory structures constructed before December 31, 2016 and more than 200 square feet can be demolished and rebuilt to include an ADU.  While this might encourage more accessory structures to come into compliance, it does not create a pathway for future new garages and carriage houses to have the option for an ADU.

 

The size of the ADU is intended to scale based on the lot size.  A minimum lot size of 5,000 square feet is required, allowing for an ADU of up to 600 square feet.  If the lot size is larger than 7,200 square feet, the ADU can be up to 800 square feet.

At least one off-street parking space is required in cases where the property is not within ¼ mile of a bus stop, or where parking cannot be provided as tandem or stacked parking in a drive that is located out of the required front yard.

 

There have been many community questions about enforcement.  Several proposed provisions offer means to enforcement, including owner-occupancy, a minimum rental/lease period of 30 days, deed restriction, required housing inspections, and others.  Most notably, applying the definition of Family in Section 5:7 to both the primary residence and ADU, requires occupancy on the site be limited to that of a single family residence without an ADU. By limiting occupancy to two persons plus their offspring living as a single housekeeping unit, staff feels that the provision allows for limitation on intensity of use. 

 

The deed restriction states that an ADU cannot be sold separately from the primary dwelling unit., e.g. as a condo.  It also indicates that the Certificate of Occupancy is in effect for the ADU while owner-occupied (subject to allowed temporary absences).  It also notes that the deed restriction shall run with the land and remain binding for successive owners.  Lastly it includes a provision where the deed restriction may lapse upon removal of the accessory dwelling unit.

 

If adopted, staff will develop an ADU guide to help potential homeowners understand the new regulations and requirements, including cost estimates and information on relevant housing and building codes.

 

If adopted, staff recommends consideration of incentives that could be provided in return for specific affordability limits.  Incentives could include fee waivers, work with architects on usable plans, and potential development of loan products with local banks or credit unions that can be used to provide attractive mortgages leveraged in return for affordability requirements.

5:10.2. - R1A, R1B, R1C, R1D, R1E single-family dwelling district.

(1)                     Intent.

(a)                     These single-family residential districts are designed to provide an environment of predominantly low-density, single-family detached dwellings, along with other related facilities which serve the residents in the district such as schools, recreational facilities, parks and churches. These districts should be convenient to commercial facilities and public transportation.

(b)                     It is the purpose of these districts to encourage the preservation and the continuation of the longstanding residential fabric in existing neighborhoods of predominantly 1-family dwellings, along with other related facilities which serve the residents in these districts.

(c)                     Accessory dwelling units are allowed to enable a new housing prototype that respects the look and scale of single-family neighborhoods while: supporting more efficient use of existing housing stock and infrastructure; providing housing that responds to changing family needs, smaller households, and increasing housing costs; providing accessible housing for seniors and persons with disabilities; and supporting affordable housing goals.

(cd)                     Application of the R1D and R1E district in newly developing areas may require a greater degree of services than the less dense 1-family dwelling districts. To assure health, safety and welfare, any future R1D or R1E zoning in newly developing areas should be contingent upon the availability or provision of adequate services to serve such higher densities, in addition to other pertinent planning considerations.

9.                     No building or other use of land except landscaped areas shall be situated within 30 feet of any adjacent residential property.

(e)                     One accessory apartment, subject to the following standards:

6.                     For purposes of this section, any new accessory recreational facility or permanent addition to an existing accessory recreational facility at a private swimming club will require a plot plan showing the existing and proposed structures and improvements on the site, instead of a site plan, as part of the special exception use application.

(4)                     Permitted accessory uses.

(a)                     Family day care homes in any dwelling if licensed by the State of Michigan Department of Social Services.

(b)                     Group day care homes in 1-family dwellings only if licensed by the State of Michigan Department of Social Services and if the following standards are met:
