Full Breakdown
6(k), titled "Nonconformity," governs garage conversions directly: "In no event shall the establishment of an ADU create a new nonconformity or expand an existing nonconformity. 6, including the one-ADU-per-lot cap in subsection (a), the 1,200-square-foot maximum and 300-square-foot minimum floor area in subsection (c), the two-story height cap in subsection (e), the one-or-two-space parking requirement in subsection (g), and the 10-foot (one-story) or 15-foot (two-story) rear setback in subsection (h). If the existing garage sits inside a required setback, or the lot already carries a nonconforming condition the conversion would deepen, such as inadequate side yard or excess lot coverage, the conversion is barred outright rather than grandfathered in.
5, and go through the site plan and/or conditional use review required by § 405's introductory paragraph before the city issues any permit for the converted space.
Violations & Fines
Converting a garage into livable space without a permit, or in a way that creates or worsens a zoning nonconformity, violates § 405.1.6(k) and is enforced through the city's code compliance process, which can require the space be restored to non-habitable accessory use until it meets every ADU standard or is properly permitted.
