Cleveland ADU rules at a glance
Cleveland follows local ordinances layered on top of Ohio state ADU law. Typical restrictions cover maximum size (often 800–1,200 sqft), height (16–25 feet), side setbacks (4 feet minimum in most jurisdictions), parking (often waived near transit), and owner-occupancy. Buildability™ reads Cleveland's specific code against your exact lot.
Why this matters
ADU permits in Cleveland typically take 60–180 days and cost $15,000–$50,000+ in soft and hard costs combined. Before paying a designer or contractor, verify your lot's eligibility — setbacks, existing FAR, utility access, and local overlays can block a build that looks fine on paper.
