On Cook County highways and unincorporated roads, only the Cook County Department of Transportation and Highways may paint or authorize curb markings such as red no-parking, yellow loading, or blue accessible zones. Private curb painting is unauthorized and unenforceable, and varies suburb to suburb on local streets.

Passive panhandling is constitutionally protected speech in Illinois, but aggressive solicitation that touches, follows, or threatens a person can be charged as assault under 720 ILCS 5/12-3.05. Cook County Code Ch. 58 mirrors these limits in unincorporated areas; suburbs add their own ordinances.
Cook County has no countywide skateboarding ban. Forest Preserve District of Cook County rules under Ch. 90 prohibit skateboarding on most preserve roadways and trails. The Cook County Highway Department prohibits skating on county arterials. Suburban Cook municipalities each set their own downtown and sidewalk skateboarding rules.
Loud or unruly gatherings in unincorporated Cook County are enforced under Code Ch. 58 disorderly conduct and noise provisions, plus Illinois Municipal Code 65 ILCS 5/8-3-1 home rule authority used by suburbs. Many Cook municipalities adopted social host or unruly-gathering ordinances making hosts liable for fines and police-response cost recovery.
Illinois bars loitering only when paired with specific intent under 720 ILCS 5/26-1 disorderly conduct or narrow statutes such as prostitution loitering. Cook County Code Ch. 58 mirrors these limits. City of Chicago v. Morales struck broad gang-loitering ordinances, narrowing how all Cook municipalities enforce.
The Smoke Free Illinois Act (410 ILCS 82) bans smoking in enclosed public places and within 15 feet of building entrances. Cook County DPH enforces in unincorporated areas and contracting suburbs. Many Cook municipalities added park, beach, and outdoor-dining smoking bans on top of the state floor.

The Metropolitan Water Reclamation District of Greater Chicago provides reclaimed effluent for industrial cooling, irrigation, and biosolid reuse under Illinois EPA NPDES permits, but residential purple-pipe systems are rare.
Cook County Chapter 38 environmental control rules and Illinois Pollution Control Board Title 35 Part 901 set 75 dBA daytime construction equipment limits at residential property lines in unincorporated Cook. Most suburbs adopt parallel municipal noise ordinances with similar daytime caps.
625 ILCS 5/12-602 requires every motor vehicle to maintain a working muffler and bars excessive or unusual noise; Cook County Chapter 38 layers receiving-land dBA limits on idling delivery trucks. Suburbs add their own loading-dock and idling restrictions enforced by local police.
Hospital helipads in unincorporated Cook County require a Chapter 32 building permit plus Illinois Department of Public Health licensure under 77 IAC 250 hospital regulations. EMS helicopter flight noise itself is FAA preempted; only siting, lighting, and structural review are local.
Helicopter operations over Cook County fall under exclusive FAA jurisdiction under 49 USC 40103, so neither the county noise ordinance nor municipal codes can directly limit helicopter altitude or routes. Complaints route to the FAA Chicago FSDO and O'Hare TRACON.
Helicopter flight paths through Cook County airspace are sequenced exclusively by the FAA Chicago TRACON (C90) and O'Hare and Midway towers. State and local governments have no authority to designate or close in-flight rotorcraft routes under 49 USC 40103 federal preemption.
Both O'Hare and Midway are City of Chicago Department of Aviation airports operating under FAA Part 150 noise compatibility programs. Cook County has no county-owned commercial airport and therefore no county-level engine run-up rules; CDA airfield-use procedures govern run-ups.
Cook County Chapter 38 environmental control rules and Illinois Pollution Control Board Part 901 set octave-band sound limits that capture low-frequency bass through 31 Hz and 63 Hz bands. dB(C) measurements supplement dB(A) when complaints describe rumble or thumping bass.
