Attached, internal, and junior ADUs have the same maximum height limit as the primary dwelling unit. Detached ADUs are limited to 16 feet.
The municipality shall provide a ministerial review process which is not based on a discretionary approval for an ADU. The process shall take no less than 120 days.

ADUs cannot be sold separately from the primary dwelling units.
Connection and utility fees shall be reasonable, and shall not be disproportionately higher than those to develop primary dwellings, so as not to deter the development of ADUs. If a private sewage disposal system is used, such as a septic system, review and approval by a local health officer may be required. ~ State Standards
