Rental conversions in Cleveland

In a Cleveland One-Family District, a house may be occupied by no more than one family plus up to two roomers or boarders.¹¹ Cleveland's Two-Family District permits houses occupied by no more than two families plus up to two roomers or boarders, along with everything allowed in a One-Family District.¹¹ Look up your parcel's district before you design anything, because a second kitchen in a One-Family District is a different conversation.

In a Cleveland Two-Family District, the Board of Zoning Appeals may, after a public hearing, allow an existing house to be remodeled into three to six units if each unit has at least two rooms and a bathroom, the lot is large enough, the outside shows no sign of more than two families, and there is parking for one car per family.¹¹

Cleveland's planning staff say a typical city residential lot is about 40 by 100 feet, or 4,000 square feet, while some conventional residential districts require 4,800 to 6,000 square feet, so an ordinary lot can be nonconforming.¹⁵ If your lot is small for its district, expect the city to ask questions even about a change that fits inside the existing walls.

Cleveland's Form-Based Code lists accessory dwelling units among its house-scale building types, alongside single-family homes, two-family homes and small buildings of three or four units.¹⁶ Cleveland's Form-Based Code applies only to properties that have been legislatively mapped into a form-based district, including the Detroit Shoreway and Cudell, Hough, Opportunity Corridor and Innovation Square pilots adopted in 2024 and the Housing Innovation District adopted in 2026; the rest of the city stays under conventional zoning.¹⁷

Outside those mapped districts, we found no city rule that allows a separate backyard unit, so a detached cottage or a unit over a garage should start with a call to the City Planning Commission. Cost vs. Value's ADU job is a new one-story, 660-square-foot detached unit on a slab, with a bedroom suite, a bath with walk-in shower, a kitchen, a mini-split heat pump, a stacked washer and dryer, and a paved parking space.¹⁸

Cleveland's rental registration covers every property the owner isn't living in, including units occupied by family members or friends even if nothing is paid, and a rental must be registered before tenants move in.¹⁹ An owner who lives outside Cuyahoga County and its neighboring counties (Summit, Lake, Portage, Medina, Lorain and Geauga) must name a Local Agent in Charge in a notarized affidavit before Cleveland issues a Certificate Approving Rental Occupancy.¹⁹

Cleveland's code presumes that any residential rental unit built before January 1, 1978 has lead-based paint, and a lead-safe certification is valid for two years from the date it is issued.³ When registering a Cleveland rental built before 1978, the owner must upload the unit's Lead Safe Certificate to the registration, and buildings with four or more units also need an HVAC certification.¹⁹

EPA's lead renovation rule generally doesn't cover homeowners working on their own pre-1978 homes, but it does apply if you rent out all or part of your home.²⁰ Before a renter signs a lease for most pre-1978 housing, federal law requires the landlord to disclose known lead-based paint and hazards, share available records, hand over EPA's Protect Your Family From Lead pamphlet and include a Lead Warning Statement.²¹

Cleveland's short-term rental law, passed in June 2026, requires a city license before a home is rented to guests for 30 consecutive days or fewer, with a $150 fee to apply and $150 for each yearly renewal.²²

Under Cleveland's short-term rental law, the home needs a certificate of occupancy, lead-safe certification, at least $500,000 in liability insurance, smoke and carbon monoxide alarms and a kitchen fire extinguisher, and a room below grade can't be used as a bedroom unless it meets habitable-room standards.²² Cleveland's short-term rental law caps short-term rentals at 10 percent of the residential units on a block, allows them in One-Family Districts subject to that cap, and requires a license to be revoked after three nuisance incidents in a year.²²

The Residential Code of Ohio requires the units of a two-family dwelling to be separated by wall and floor assemblies with at least a 1-hour fire-resistance rating, or a 1/2-hour rating in a building with a full sprinkler system.¹⁴ In an old double, that often means a new rated ceiling between the floors and closing up a shared back stair.

The Residential Code of Ohio requires every sleeping room, including one in a basement, to have at least one operable emergency escape and rescue opening, unless the home has an automatic sprinkler system and the basement has the means of egress the code spells out.¹⁴ The U.S. Fire Administration says homeowners and landlords should put smoke alarms in every bedroom, outside each sleeping area and on every level, test them monthly, and replace them 10 years from their manufacture date.²³

Many conversions in Cleveland are for family rather than rent: a parent on the first floor of a double, a grown child upstairs. Even then, Cleveland's registration rule, described above, treats a relative's unit as a rental.

If the unit is for someone older, put it on the ground floor and plan the bath for a walker or wheelchair from the start. NAHB's Certified Aging-in-Place Specialist (CAPS) credential trains remodelers in home modifications for aging in place.²⁴

Before you sign a contract, look the company up yourself. To build or rehabilitate homes in Cleveland, contractors must be bonded, insured and registered with the Department of Building and Housing, electricians and plumbers must also be licensed, and homeowners can call the department to confirm a contractor is registered.²⁵ Check an Ohio license
