Appendix A: Frequently Asked Questions

complete[12] . The standards should be appropriate to, and consistent with, meeting the local government’s regional housing need and facilitate development at the permitted density. (Gov. Code, § 65589.5, subd. (f)(1).) However, it should be noted that compliance with historic preservation laws may otherwise constrain the approval of a housing development.

Under the Housing Accountability Act, is the retail/commercial component of a mixeduse project subject to review when the housing component must be approved?

Yes. The local government may apply objective, quantifiable, written development standards, conditions and policies to the entirety of the mixed-use project, so long as they were in effect when the application was deemed complete. (Gov. Code, § 65589.5, subd. (f)(1).)

Does the Housing Accountability Act apply to subdivision maps and other discretionary land use applications?

Yes. The HAA applies to denials of subdivision maps and other discretionary land use approvals or entitlements necessary for the issuance of a building permit (Gov. Code, § 65589.5, subd (h)(6).)

Does the Housing Accountability Act apply to applications for individual single-family residences or individual Accessory Dwelling Units (ADUs)?

No. A “housing development project” means a use consisting of residential units only, mixed use developments consisting of residential and non-residential uses with at least two-thirds of the square footage designated for residential use, or transitional or supportive housing. Because the term “units” is plural, a development has to consist of more than one unit to qualify under the HAA (Gov. Code, § 65589.5, subd. (h)(2).).

Does the Housing Accountability Act apply to an application that includes both a singlefamily residence and an Accessory Dwelling Unit?

Yes. Since an application for both a single-family residence and an ADU includes more than one residential unit, the HAA applies (Gov. Code, § 65589.5, subd. (h)(2).)
