Tinley Park's zoning code caps the percentage of a residential lot that can be covered by buildings and impervious surfaces. Typical R-3 districts limit principal building coverage to approximately 30-35% of lot area.
Lot coverage in Tinley Park is regulated by the zoning ordinance to preserve open space, manage stormwater, and maintain neighborhood character. In R-3 single-family districts, principal building coverage is typically capped at around 30-35% of lot area, with an additional allowance for accessory structures. Impervious surface limits (including driveways, patios, and pools) are often capped at 50-60% combined. Denser multi-family and commercial districts have different coverage allowances. Coverage calculations include all building footprints, patios, decks over a certain height, driveways, and walkways. Exceeding coverage triggers stormwater review and may require detention improvements. Owners planning additions, new driveways, or patios should verify compliance with Community Development before proceeding.
Exceeding coverage: permit denial, stop-work orders, fines up to $1,000 per day, and required removal of excess impervious surface.
