Summary
Elk Grove lets homeowners convert an attached or detached garage into livable space by permitting it as an accessory dwelling unit under EGMC Section 23.90.040, with a 150-square-foot expansion allowance and no added setback if the garage keeps its footprint.

Full Breakdown
90, since the Community Development Director reviews these conversions administratively rather than as a remodel. " Under subsection (D)(1), a garage converted this way is exempt from the chapter's setback standards in subsection (G) as long as it maintains side and rear setbacks sufficient for fire and safety, and the conversion may add up to 150 square feet beyond the garage's existing footprint, limited to space needed for ingress and egress. Subsection (G)(1) confirms no additional setback applies to an existing accessory structure converted into an ADU, but any converted space must meet Building Code requirements for protection of life and safety, meaning a full building permit review covering egress windows, ceiling height, insulation, and fire separation is still required even though no discretionary land-use entitlement is needed.
040(J), which requires one additional off-street parking space per ADU bedroom unless the unit qualifies for an exemption, such as being part of an existing structure or located within a half-mile of a bus stop. 130(C), which applies only when a lot is being split into two dwelling units and requires the vacated garage door opening to be replaced with matching wall covering, siding, or windows.
Violations & Fines
Because a garage-to-ADU conversion is processed through zoning clearance and building permit review rather than by self-certification, occupying a converted garage as habitable space without the building permit sign-off required by Section 23.90.040(G)(1) exposes the space to code enforcement as unpermitted construction. The City's Building Division can red-tag work that lacks inspection sign-off for electrical, plumbing, and life-safety items, and an ADU built without permits cannot be legally rented under Section 23.90.040(I)'s 30-day minimum rental term protection. Owners who skip the parking analysis under subsection (J) risk a correction notice requiring either replacement parking or documentation of an exemption before final inspection.
