Oak Lawn permits native plant gardens, pollinator plantings, and naturalized landscaping provided they are intentionally designed, maintained, and do not violate the 8-inch grass/weed height limit for unmanaged turf areas. Documentation of intentional design is recommended.
Oak Lawn's property maintenance code caps grass and weed height at 8 inches for traditional lawns, but intentional native plant gardens, prairie-style plantings, and pollinator landscapes are increasingly recognized. Residents planning native landscaping should document the design (plant lists, garden boundaries, maintenance plan) and notify Code Enforcement in advance to avoid being mistaken for neglect. Plants must be from cultivated native species; noxious weeds listed under 505 ILCS 100 (ragweed, Canada thistle, Johnson grass, etc.) must still be controlled. Front yard native plantings are generally allowed if maintained with defined borders, paths, and visible care. Natural areas work best in side and rear yards. Invasive non-native species like buckthorn, garlic mustard, and Japanese knotweed should be removed. Contact Code Enforcement at (708) 499-7830 to discuss plans before installation.
Untended 'natural' areas that look like neglected turf can be cited under the 8-inch grass and weed ordinance. Noxious weeds present in native gardens must still be controlled under state law. Disputes typically resolve when the property owner documents intentional design and maintenance.
