Full Breakdown
UDC § 4.02.03(G)(2) waives Indio's standard four-foot side and rear yard ADU setback when a homeowner converts an existing accessory structure, the code names a detached garage as the example, into an ADU, provided the new unit sits in the same location and at the same dimensions as the structure it replaces. The same waiver covers ADUs built inside existing living area of the house. Building and Fire Code requirements can still force added clearance despite the waiver. Any expansion beyond the original garage footprint falls back under the standard setback and other development standards set out in UDC § 4.02.03.
Violations & Fines
Demanding a full four-foot setback on a like-for-like garage-to-ADU conversion, or ignoring Building and Fire Code clearance needs, misapplies UDC § 4.02.03(G)(2).
