Summary
Auburn's accessory dwelling unit rule only works if the property owner lives on site: Zoning Ordinance Section 408.02(D)(4)(h) requires the principal dwelling unit to be owner-occupied before an ADU can be approved, and the code allows no waiver or variance from that condition.
These provisions apply to a residential unit that is located in an owner-occupied single family detached home, or is a separate structure on the same lot as an owner-occupied single family dwelling. ... The principal dwelling unit must be owner-occupied; and an accessory dwelling unit shall not be rented or used as income producing property. ... No accessory dwelling unit shall be approved unless all the conditions set forth above are met. No waivers or variances to this Section shall be allowed as a means of accommodating an accessory dwelling unit.
Full Breakdown
Auburn's accessory dwelling unit standards apply only to owner-occupied property from the outset. " That means an absentee landlord who buys a house purely as a rental cannot add a garage apartment or in-law suite and call it an accessory dwelling unit under this section; the owner has to actually live in the principal home. The ordinance backs this up with its closing clause in subsection (i): "No accessory dwelling unit shall be approved unless all the conditions set forth above are met. " That forecloses the usual escape route of appealing to the Board of Zoning Adjustment for relief from the owner-occupancy condition.
In practice, the Planning Department checks owner-occupancy at the zoning-certificate stage required under Section 804 before any ADU construction or conversion can begin, and if the owner later moves out, the unit falls out of compliance with the section that authorized it in the first place.
Violations & Fines
An accessory dwelling unit built or approved without the principal home being owner-occupied is not just a fine risk; Section 408.02(D)(4)(i) means the unit cannot lawfully be approved at all, and no waiver or variance can cure the defect. Where a non-compliant unit is built anyway, the general Zoning Ordinance penalty applies: up to a $500 fine and six months in city jail under Section 909, per day of violation.
