AN ORDINANCE AMENDING ANCHORAGE MUNICIPAL CODESUBSECTIONS 21.05.070C.1.g., TABLE 21.05-3, TABLE OFACCESSORY USES; 21.05.070D.1., DEFINITIONS AND USE-SPECIFIC STANDARDS FOR ALLOWED ACCESSORY USES ANDSTRUCTURES, ACCESSORY DWELLING UNIT (ADU); AND21.06.020B., TABLE 21.06-1, TABLE OF DIMENSIONALSTANDARDS, TO ENCOURAGE DEVELOPMENT OF ACCESSORYDWELLING UNITS.

The Anchorage 2040 Land Use Plan, adopted by the Assembly in September 2017, anticipates a need for an additional 1,000 compact housing units in the Anchorage Bowl by 2040. This ordinance is an effort to meet the Anchorage 2040 Land Use Plan's goal of providing additional compact housing. At the time of writing, the amount of public-sector revenues and expenses are not yet quantifiable.

This re-write of the Accessory Dwelling Unit regulations is intended to meet the demand for additional compact housing within the Anchorage Bowl. As of this writing, there are individual property owners waiting for the adoption of this ordinance to construct new Accessory Dwelling Units.

Assembly Memorandum

No. AM 327-2018

Meeting Date: May 8, 2018

From: MAYOR 1 2 Subject: AN ORDINANCE AMENDING ANCHORAGE MUNICIPAL CODE 3

SUBSECTIONS 21.05.070C.1.G., TABLE 21.05-3, TABLE OF 4 ACCESSORY USES; 21.05.070D.1., DEFINITIONS AND USE-5 SPECIFIC STANDARDS FOR ALLOWED ACCESSORY USES 6 AND STRUCTURES, ACCESSORY DWELLING UNIT (ADU); 7 AND 21.06.020B., TABLE 21.06-1, TABLE OF DIMENSIONAL 8 STANDARDS, TO ENCOURAGE DEVELOPMENT OF 9 ACCESSORY DWELLING UNITS. 10

11 12 The Live. Work. Play. Housing Area of Focus (LWP) of the Anchorage 13 Economic Development Corporation (AEDC) was tasked with identifying 14 opportunities to augment housing development in support of workforce 15 development in Anchorage. A subcommittee of the LWP Housing Area of 16 Focus met regularly to work, research, and ultimately propose this Accessory 17 Dwelling Unit ordinance. The subcommittee was broadly represented and 18 included MOA staff, local developers, and members of LWP Housing. 19 20 This ordinance amends Accessory Dwelling Unit regulations in AMC chapters 21 21.5, Use Regulations and 21.6, Dimensional Standards and Measurements. 22 These amendments are intended to expand the supply of residential rental 23 units, make homeownership easier to attain and sustain, and encourage the 24 development of this type of alternative housing. This change will allow more 25 efficient use of residential property, allow development that is compatible with 26 existing neighborhoods, and create more affordable housing alternatives. While 27 this ordinance provides increased flexibility in the development of ADUs, it does 28 not change the underlying zoning density allowances. 29 30 The Anchorage 2020—Anchorage Bowl Comprehensive Plan (Anchorage 31 2020) and the Anchorage 2040 Land Use Plan (2040 LUP) support the need for 32 alternative affordable housing types like Accessory Dwelling Units. Policies 16 33 and 58 of the Anchorage 2020 call for the adoption of standards that provide a 34 variety of lot sizes and housing types and encourages more affordable housing 35 for low-income residents. 36 37

AM regarding Development of Page 2 Accessory Dwelling Units

The 2040 LUP supplements Anchorage 2020 with updated forecasts of future 1 housing need and more specific land use guidance. It identifies a need for up to 2 21,000 additional residential units, and a more diverse housing supply with a 3 greater number of “compact” housing units including accessory dwellings. The 4 2040 LUP targets an additional 1,000 new ADUs in the Anchorage Bowl by the 5 year 2040. 6 7 The Anchorage Bowl currently receives on average 20 applications for new 8 ADUs annually. To meet the goal of the 2040 LUP, that average would need to 9 double. The subcommittee believes creating more flexible ADU regulations 10 could help in narrowing the gap that currently exists in compact housing. 11 12 This ordinance proposes six primary changes to existing Accessory Dwelling 13 Unit regulations. They are as follows: 14 15

• Allowing detached Accessory Dwelling Units in the R-1 and R-1A 16 zoning districts. 17

18 • Increasing the maximum size of Accessory Dwelling Units. 19

20 • Provision to, in some cases, allow parking to be provided on street. 21

22 • Reducing setbacks for detached Accessory Dwelling Units. 23

24 • Increasing the maximum height of accessory structures in the R-1 25

and R-1A zoning districts to 25 feet. 26 27 • Detached accessory units taller than 15 feet require a 10-foot side 28

setback abutting a neighboring R-1 or R-1A lot. 29 30 31
