Start With Your Columbus Property
In a house with a basement, compare the wall-floor joint after rain with the ceiling beneath bathrooms. In an apartment, note whether the wet spot aligns with a unit above. Give the repairer the pattern and dates, rather than asking only for the stain to be painted.
Columbus Code Enforcement
Columbus enforces a Housing Code for dwellings as well as separate zoning, nuisance and environmental codes. Ask for the housing route when the concern is a leaking roof, plumbing defect or deteriorated interior.
Before you contact them:Identify the street address and unit, list the damaged building components, and keep the landlord notice and photos together. If a violation notice is issued, use the named officer and case details for follow-up.

Ohio mold law snapshot
Ohio does not have a mold-specific statute, but habitability rules still apply.
Under Ohio Revised Code Section 5321.04, landlords must comply with all applicable building, housing, health, and safety codes that materially affect health and safety. They must make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition. Landlords must also keep all common areas safe and sanitary, maintain electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures in good working order, and supply running water, reasonable amounts of hot water, and reasonable heat at all times. This implied warranty of habitability cannot be waived by the landlord or tenant.

Repair Notices and Rent Decisions
Start with these Ohio rules, then check the local regulations section and your property's coverage. A statutory notice period is not always a deadline for finishing every repair. Keep proof of notice and get local legal advice before changing rent payments or ending a lease.
How long does a Columbus landlord have to fix mold?
For the remedies in Ohio Revised Code 5321.07, after written notice the landlord has a reasonable time based on severity and the work needed, or 30 days, whichever is sooner, to remedy the condition. A tenant must be current in rent and check the section's exclusions before using court rent deposits or termination. This is not a universal 30-day waiting period for every hazard.

Can Columbus tenants withhold rent for mold?
Ohio allows rent withholding through a formal rent escrow process. Tenants cannot simply refuse to pay rent; they must deposit rent with the clerk of the municipal or county court. Before using this remedy, the tenant must: (1) provide written notice to the landlord specifying the violation, (2) be current on rent payments, (3) allow the landlord a reasonable time (up to 30 days) to remedy the condition. A tenant who simply refuses to pay rent without using the escrow process may be subject to eviction. This remedy does not apply to landlords who own three or fewer rental units and provide proper written notice of this fact.

Does mold in Columbus require relocation?
Unclear as a standalone statewide mold relocation benefit in the sources reviewed for this guide. If mold or remediation makes the unit unsafe or unusable, Ohio tenants should look to the cited habitability, essential-services, condemnation, disaster, or lease-termination rules and ask legal aid whether rent abatement, substitute housing, temporary vacancy, or termination applies.

Does mold have to be disclosed in Columbus?
Ohio does not require landlords to disclose mold or high mold concentrations to prospective tenants. There is no state statute mandating mold disclosure in rental properties. However, for real estate sales, Ohio Revised Code Section 5302.30 requires sellers of residential properties (up to four units) to disclose known water damage, including mold, and any mold inspection results or remediation efforts. Federal lead paint disclosure requirements apply to properties built before 1978.
