How Tinley Park Handles Building Safety: A Practical Guide

Tinley Park maintains 103 local ordinances across all categories, and 9 of those deal specifically with building safety. Here is a breakdown of what the city actually requires, what is prohibited, and where Tinley Park falls on the strict-to-permissive spectrum compared to other cities.

Scaffold & Sidewalk Shed

Any scaffold or ladder in Tinley Park that overhangs or could fall onto a public street, alley, or other public place must be firmly built, properly safeguarded, and cannot go up without a permit from the Director of Public Works. Village Code § 99.012 also bars leaving tools or materials where they could fall into a public way.

Key details: Permit required from: Director of Public Works. Trigger: Scaffold/ladder overhangs or could fall on public way. Loose materials: Cannot be left where they could fall into street. Original codification: '77 Code § 133.007, Ord. 62-0-004 (1962). Penalty: $50 to $750 per day, § 10.99.

Erecting a scaffold or ladder over a public way without the Director of Public Works' permit, or leaving tools where they can fall into a street, sidewalk, or alley, is punishable under the general penalty at Village Code § 10.99: a fine of $50 to $750, with each day the unpermitted or unsecured condition continues counted as a separate offense.

Electrical Permits

Tinley Park requires a permit for all electrical work, including low-voltage systems like alarms and communications cable, under the village's adopted 2020 National Electrical Code. Only licensed, bonded contractors can pull permits for most jobs, and commercial work always requires a licensed contractor.

Key details: Adopted code: 2020 National Electrical Code (NFPA 70). Contractor requirement: Licensed, bonded, registered with Building Dept.. Homeowner permit: Own residence only, 6-month residency. Commercial work: Licensed contractor required, no exceptions. General penalty: $50–$750 per day, § 10.99.

Doing electrical work without a village permit, using someone else's permit, or a contractor letting an unlicensed person work under their permit is a code violation. Because Chapter 155 sets no separate fine for this subsection, it falls under the village's general penalty in § 10.99: a fine of not less than $50 nor more than $750, with each day a violation continues counted as a separate offense. Courts may also add conditional discharge, restitution, community service, or an order to correct the violation by a set date.

Carbon Monoxide Detectors

Tinley Park has required carbon monoxide alarms since January 1, 2007 in every dwelling unit with a sleeping room, placed within 15 feet of the sleeping area. Owners must install them, landlords must keep them operable at lease start, and willful failure is a Class B misdemeanor.

Key details: Effective date: January 1, 2007. Placement: Within 15 feet of every sleeping room. State authority: Illinois Carbon Monoxide Detector Act, P.A. 094-0741. Install duty: Owner supplies and installs all alarms. Penalty: Class B criminal misdemeanor for willful failure.

Willful failure to install or maintain a required carbon monoxide alarm in operating condition is a Class B criminal misdemeanor under § 155.07(E)(2)(A)(4)(g), a criminal charge rather than a civil fine. Illinois classifies a Class B misdemeanor as punishable by up to six months in jail and a fine up to $1,500, and enforcement runs through the Building Department's inspection process alongside the Electrical Inspector's oversight of the wiring standards.

Building Inspections

Tinley Park requires the Building Official to inspect construction at defined stages before work may proceed, from footing and foundation through rough framing and insulation to a final inspection. Contractors must call the Building Department at least 48 hours ahead to schedule (two hours for concrete pours before 2:30 p.m.), and no rough framing inspection happens until electrical, plumbing and HVAC rough-ins are approved first.

Key details: Footing inspection: after excavation, before concrete pour. Rough inspection: before insulation, lath or gypsum board. Notice required: 48 hours by phone, excluding weekends. Concrete inspection notice: 2 hours, called in by 2:30 p.m.. Final inspection: after fire/alarm/suppression testing complete.

Building past an inspection point without the Building Official's written approval violates § 155.07(A)(1)J's ban on working outside the Code's terms, exposing the owner or contractor to the general misdemeanor penalty of up to $750 per day under § 155.07(A)(1)K. A Building Official who finds work does not comply with an inspected stage will refuse approval and can direct that a stop-work order be posted at the site until corrected.

Plumbing Permits

Tinley Park's Building Code makes the Illinois State Plumbing Code (2014), as amended, the governing standard for every plumbing installation, alteration, repair and replacement in the village, including water, sewage and medical gas systems. No registered plumbing contractor may start work without first securing a village permit, and the Plumbing Inspector can halt any job performed without one until the proper permit is in hand.

Key details: Adopted plumbing code: Illinois State Plumbing Code (2014), as amended. Permit required before: any plumbing installation or alteration. Enforcement: Plumbing Inspector can stop unpermitted work. Covers: water, sewage and medical gas systems. Adopting sections: § 155.01(A) and § 155.07(A)(1).

Performing plumbing work without a village permit lets the Plumbing Inspector shut the job down on the spot and order all workers to stop until a permit is secured. Continuing work after a stop-work order is unlawful and, under the Building Code's general penalty provisions, can draw a fine of up to $750 per day the violation continues, in addition to any separate charge for unlicensed plumbing work.

Childcare Center Rules

Any operation caring for three or more unrelated children under six, or three or more adults needing supervised care, for part or all of a day up to 9:00 p.m. counts as a day care center in Tinley Park and must be licensed. Village Code Chapter 114 makes running one without a license unlawful.

Key details: Regulated threshold: 3+ unrelated children under age 6. Also covers: 3+ adults needing supervised care. Cutoff time: Care ending no later than 9:00 p.m.. License fee: Flat rate, set by § 110.25. Max penalty: $500 fine or 6 months jail.

Operating a day care center in Tinley Park without the § 114.02 license is punishable under § 110.99: a fine of up to $500 per offense or a jail term of up to six months, with each day of unlicensed operation treated as a separate offense. The village enforces the license requirement independent of any separate state licensing action against the same facility.

Building Permits

Tinley Park requires a building permit before any excavation, grading, construction, addition, remodeling, alteration, repair or demolition begins. Applications go through the Building Official using village forms, and permit fees follow the fee schedule in Chapter XIII of the Building Code. Residential permits for one- and two-family homes, decks, sheds and garages expire in 180 days; all other permits run one year.

Key details: Permit required for: excavation, construction, additions, demolition. Residential permit life: 180 days from issue date. Other permit life: 1 year, two 3-month extensions. Renewal fee: first free, second 50% of original fee. Survey required: sealed Plat of Survey with application.

Building without the required permit, or varying from the approved plans without written Building Official approval, is unlawful under § 155.07(A)(1)J and K. Violators face a misdemeanor charge with a fine up to $750 per offense, and each day the violation continues counts as a separate offense. The village may also sue in civil court to enjoin continued unpermitted work, and unpaid permit-related fees bar the owner from obtaining any future permit for 30 days.

Elevator Maintenance

Village Code Chapter 150 requires every elevator, escalator and similar passenger equipment in Tinley Park to be inspected at least once every six months by the Building Commissioner's elevator inspector, with no new unit allowed into service before its first inspection. Owners must post the resulting safety certificate and keep equipment in good repair or face a fine of up to $500 per day.

Key details: Inspection frequency: at least every 6 months. New equipment: barred until first inspection passes. Inspector demand response: within 5 days. Max fine: $500 per day, § 150.99. Enforcing official: Building Commissioner.

Section 150.99 makes any violation of the elevator chapter punishable by a fine of up to $500, with each day the violation continues or occurs counted as a separate offense. That penalty does not limit other legal remedies available to the village under the building code or otherwise, including the Building Commissioner's authority to shut down unsafe equipment under § 150.02 until it is repaired and recertified.

Fire Sprinkler Requirements

Tinley Park requires automatic sprinkler systems in buildings over 7,500 square feet or exceeding two stories or 27 feet when used for assembly, educational, industrial, institutional, mercantile or storage occupancies, and in any building over four stories or 55 feet regardless of use, under Fire Prevention Code § 95.17.

Key details: Size trigger: Over 7,500 sq ft or 2 stories/27 ft. Height trigger: Over 4 stories or 55 ft, any use. Plan approval: ISO/insurer, then Fire Prevention Officer. Penalty: Up to $500 or 6 months, § 95.99.

Failing to install a required sprinkler system, or installing one without the Fire Prevention Officer's approved plans, is a misdemeanor under the Fire Prevention Code's general penalty section, § 95.99, punishable by a fine of up to $500 or up to six months imprisonment, with each ten days a violation continues counted as a separate offense.

The Bottom Line

Tinley Park's building safety rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Tinley Park is broadly strict or permissive.
