Full Breakdown
Toledo's 2025 accessory dwelling unit ordinance ties ADU legality to continuous owner residency. " That means the ADU cannot be rented out as an investment unit separate from the main house while the owner lives elsewhere -- the owner must occupy the principal structure, not the ADU itself, for the accessory unit to remain lawful. 0207 standards: no more than one ADU per lot (subsection A), a separate exterior entrance for the ADU (subsection C), a footprint capped at 60 percent of the primary dwelling (subsection E), and a bar on mobile homes, RVs or travel trailers serving as ADUs (subsection L).
The owner-occupancy condition was adopted by Ordinance 440-25, passed September 23, 2025, and applies for the entire time the ADU exists on the lot -- if the owner moves out of the principal dwelling, the ADU's compliance with this section lapses.
Violations & Fines
Failing to maintain owner-occupancy of the principal dwelling while an ADU exists on the lot is a Zoning Code violation under Section 1115.0201/1115.0205 (using land inconsistent with the Zoning Code / violating a permit condition). Citations carry escalating fines of $75, $150, $300 and $600 for successive offenses under Section 1115.0507(C), and the City may pursue civil collection or injunctive relief under Section 1115.0504 if the violation is not corrected.
