The State Legislature has declared that accessory dwelling units are a valuable form of housing in California. Accessory dwelling units provide housing for family members, students, the elderly, in-home health care providers, the disabled, and others, at below market prices, and within existing neighborhoods. Homeowners who create accessory dwelling units benefit from added income, and an increased sense of security. (Gov't. Code § 65852.150.)

The city has a long history of various types of accessory dwelling units. By enacting this division 17.38, the City Council intends to:

A. Establish the requirements for accessory dwelling units and junior accessory dwelling units in the city, consistent with California Government Code section 65852.2 and 65852.22;

B. Encourage the use of existing accessory dwelling units and the construction of new accessory dwelling units, consistent with this Division;

C. Help achieve the goals and policies of the General Plan Housing Element by encouraging a mix of housing types affordable to all economic segments of the community; and

D. Clarify the requirements for the various kinds of accessory dwelling units in the city. (Ord. 768 N.S., 01/2023)

An accessory dwelling unit may also include (1) an efficiency unit, as defined in Health and Safety Code section 17958.1 and (2) a manufactured home as defined in Health and Safety Code section 18007.

Affordable housing definitions:

Affordable Rent Level means that the accessory dwelling unit household’s monthly cost of rent, plus the cost of electricity, gas, water and sewer service, and garbage collection (“utilities”) is 30% or less than the upper limit of the annual gross household income, divided by 12, for a specified income category and household size as last published by the California Department of Housing and Community Development (HCD). The City shall determine maximum affordable rent levels for rent-restricted accessory dwelling units following the annual publication of the State Income Limits by HCD. In determining rent levels, the household size for rent-restricted accessory dwelling units shall be: studio, 1 person; one-bedroom, 2 persons; two-bedroom, 3 persons; and, three-bedroom, 4 persons. The cost of utilities for the accessory dwelling unit shall be included in the affordable rent level. For rent-restricted accessory dwelling units where utilities are separately metered and billed, and where the accessory dwelling unit household is responsible for the costs of that household’s use of utilities, the maximum rent shall be set at 90% of the affordable rent level. (California Health and Safety Code section 50053)

Affordable unit means a dwelling unit for sale or rent that meets the California State Department of Housing and Community Development standards of income eligibility and affordable rent levels for Alameda County. (Health and Safety Code sections 50052.5(h) and 50053.)

Gross Household Income means the total monies earned or received by all occupants of an accessory dwelling unit age 18 and over, including: wages and all types of compensation, before any payroll deductions; spousal and child support; social security, retirement, disability, insurance, and other types of periodic payments; unemployment compensation and other payments in-lieu of earnings; welfare and other public assistance; interest, dividends and other payments generated from any real or personal property; net business income; and, any other type of payment determined to qualify as income by the U.S. Department of Housing and Urban Development (HUD) and as published in HUD’s Housing Choice Voucher Program Guidebook. The annual gross household income is calculated by multiplying the monthly amounts earned or received at the time of certification by 12 and adjusting for anticipated payments and changes in amounts over the next 12 months.

Household means those persons who collectively occupy a housing unit. A household shall include any child or dependent, as defined Internal Revenue Code section 152, who is under the age of 18 or who is under the age of 24 and is a full-time student.

Household Size means the number of persons in a household.
