Tree Trimming

Cincinnati Municipal Code Chapter 743 (Urban Forestry) regulates the trimming and maintenance of public trees. Only the city Urban Forestry Division or its authorized agents may trim or prune trees in public rights-of-way. Property owners are responsible for private tree maintenance but must not damage public trees.

Native Plants

Cincinnati has no ordinance requiring or restricting native plant landscaping on residential property. The city encourages pollinator gardens through Cincinnati Parks programming. CMC Chapter 731 (Weed Control) and Chapter 1423 (Landscaping and Buffer Yards) set general vegetation standards but do not mandate specific plant species.

Key details: Native Plant Mandate: None for residential properties. Weed Control Code: CMC Chapter 731. Zoning Landscaping: CMC Chapter 1423 (commercial/multi-family). City Promotion: Cincinnati Parks pollinator garden program. Caution: Keep native gardens maintained to avoid weed citations.

Tree Removal & Heritage Trees

Cincinnati requires a permit before removing any public tree. CMC Chapter 743 prohibits removal of public trees without replacing them with trees of equivalent dollar value. The Urban Forest Manager determines tree value based on species, size, location, and condition. Permit applications must be approved or denied within 15 days.

Key details: Code Reference: CMC Chapter 743 (Urban Forestry). Permit Required: Yes, for any public tree removal. Replacement: Trees of equivalent dollar value required. Permit Timeline: Approved or denied within 15 days. Valuation: Urban Forest Manager determines based on species, size, condition.

Removing a public tree without a permit is a code violation subject to fines and compensatory restitution for the full appraised tree value.

This is one of the stricter rules in Cincinnati's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Artificial Turf

Cincinnati does not have a specific ordinance prohibiting or regulating artificial turf on residential properties. The zoning code Chapter 1423 addresses landscaping requirements for commercial development but does not restrict synthetic grass on single-family lots. Standard property maintenance and drainage rules apply.

Key details: City Prohibition: None for residential artificial turf. Permit Required: No specific turf permit needed. Zoning Code: Ch. 1423 applies to commercial/multi-family only. Drainage: Must maintain proper stormwater drainage. Historic Districts: May face additional review.
