Bonus ADU Provisions (2) The Zoning Administrator may authorize an additional accessory dwelling if: (a) The additional accessory dwelling unit is a rental unit affordable for and reserved solely for "income -eligible households," as defined in this ordinance. It is subject to an agreement specifying the affordability requirements under this subsection in order to ensure that the housing shall serve only income -eligible households for a minimum period of 50 years. The monthly rent, including basic utilities, shall not exceed 30% of the income limit for the unit, all as determined by the Director of Housing, and the housing owner shall submit a report to the office of housing annually that documents how the affordable housing meets the terms of the recorded agreement. Prior to issuance of the first building permit for a project, and as a condition of that issuance, the applicant shall execute and record a declaration in a form acceptable to the Director that shall commit the applicant to satisfying the conditions for establishing a second accessory dwelling unit as approved by the Director; or (b) The applicant makes a commitment, in the manner required by this ordinance, that the new principal structure or the new accessory structure shall contain a detached accessory dwelling unit will meet a green building standard. A second accessory dwelling unit that is proposed within an existing structure does not require the structure to be updated to meet the green building standard; or (c) The applicant designs at least one of the dwellings on the lot to meet visitability standards including a no -step entry, [36"] wide doors and hallways, a bathroom that can be used by someone in a wheelchair, and at least [300 square feet] of living space on the main level. Based on Seattle Municipal Code 23.44.041.A. 1. a. (2). "Income eligible" is not defined in the Model Local ADU Ordinance, since that can be a matter left to local discretion. Seattle has chosen to link its definition to a percentage of the U.S. Housing and Urban Development's published Median Family Income data. See Seattle Municipal Code Section 23.84A.025. This Model Local ADU Ordinance also does not incorporate a green building standard; a local government may rely on its existing standards or adopt new ones for this purpose. Seattle's green building standard is rigorous, referencing the standards in Leadership in Energy and Environment Design (LEED), passive house and living building design standards, and other standards. The green building standard was adopted by the Director of Seattle's Department of Construction as Rule 20-2017 and Inspections and can be found at Seattle.gov/d pd/codes/ dr/DR2017-20.pdf. Some other mechanisms to promote affordable ADUs are: Letting the landlord charge market rate rent, but adopting no-fault eviction protection and/or a cap on the rate of rent increase over time. • Requiring the landlord to accept Section 8 vouchers. Based on Philadelphia Fair Housing Ordinance [Chapter 9-800 of the Philadelphia Code]: • Adopting the Good Cause eviction regulations for short-term rental [less than 12 months]. 35 1 HARP - Accessory Dwelling Units: Model State Act and Local Ordinance
