If you own property in Chicago, you know that the city has rigorous standards and requirements when it comes to building maintenance and safety. As a property owner, it’s important to understand Chicago’s building inspection process, so you can keep your buildings up to code and avoid potential fines or violations. In this comprehensive guide, we’ll walk through everything you need to know about Chicago building inspections for residential and commercial properties in the Windy City.

Overview of Chicago’s Building Inspections

The City of Chicago conducts regular building inspections to ensure properties comply with the Chicago Building Code and other regulations. These inspections cover everything from structural integrity, fire safety, plumbing, electrical systems, ventilation, and more.

The Department of Buildings (DOB) oversees inspections and enforces the building codes. Violations can result in citations and fines until they are addressed and cleared. The city may also conduct spot inspections in response to complaints or after major weather events to check for damage.

Some of the main goals of Chicago’s rigorous inspection system include:

  • Ensuring buildings are structurally sound and safe for occupancy
  • Preventing electrical fires and faults through proper wiring
  • Maintaining healthy air quality and ventilation
  • Checking for water leaks, damage, or other plumbing issues
  • Requiring functioning fire alarms, sprinklers, and safety exits
  • Ensuring buildings are accessible for people with disabilities
  • Preserving Chicago’s historic building stock

Thorough inspections benefit owners by identifying issues early, before they become bigger problems. They also give tenants and visitors peace of mind that buildings meet modern life safety standards.

Types of Building Inspections in Chicago

There are a variety of building inspections that Chicago property owners should be aware of:

1. Certificate of Occupancy Inspections

A Certificate of Occupancy (CO) is required before a new building can be occupied or an existing building can have its use or occupancy changed. The CO inspection examines overall life safety issues, fire protection systems, means of egress, structural integrity, and compliance with zoning.

COs must be maintained and updated. The city requires CO inspections whenever:

  • A property changes owners
  • The building is vacant for more than a year
  • Renovations are made that require new building permits

2. Periodic Inspections

Chicago conducts periodic inspections of existing buildings to check for any new code violations. Issues with facades, balconies, exterior walls, and fire escapes are prioritized. High-rise office buildings typically get inspected every 3 years.

3. Complaint Inspections

The city will promptly inspect any property about which a complaint has been made concerning safety or building code violations. Common complaints involve issues like lack of heat, plumbing problems, or pest infestations.

4. Special Inspections

Special inspections may occur:

  • After major weather events – Chicago inspects properties after storms, flooding, or other disasters to check for structural damage. This occurred after the February 2022 winter storms.
  • Pre-purchase inspections – The city may conduct an inspection for a new owner before the sale of a building closes. This inspection focuses on potential code violations and system defects.
  • Spot inspections – Chicago frequently performs random spot inspections to proactively check for violations. These are common in high-density areas like large apartment buildings.

5. Inspections of Construction Work

Several inspections are required for new construction projects or major renovations in Chicago, including:

  • Foundation and framing
  • Electrical, mechanical, and plumbing systems
  • Energy code compliance
  • Fire protection systems
  • Occupancy permit

The number and type will depend on the scope of work. The Department of Buildings will outline the needed inspections when issuing permits.

6. Elevator Inspections

Elevators in Chicago buildings must be annually tested and permitted. The city inspects elevators, escalators, and other conveyances for compliance with safety codes and maintenance requirements.

Chicago Building Inspection Process Explained

So what exactly happens during a Chicago building inspection? Here’s an overview of the process:

Scheduling the Inspection

For city-initiated periodic inspections, the Department of Buildings will contact the property owner by mail to schedule a date. For complaint-driven inspections, the city will reach out to arrange a time after receiving the complaint.

Construction inspections must be scheduled by the contractor or owner through the city’s online permit system. Elevator inspections are also scheduled annually through the Department of Buildings.

Day of Inspection

The inspector will arrive and review all areas of the building related to the type of inspection. For example, an elevator inspection will involve examining equipment, shafts, and machine rooms. A CO inspection may cover more areas.

The inspector will be checking for compliance with the Chicago Building Code and noting any violations or deficiencies. It’s helpful for the owner or manager to accompany them in case any questions arise.

Inspector’s Report

After completing the inspection, the inspector will generate a report listing any code violations observed. Minor issues may just receive a notice, while major violations get classified as citations requiring remedy within a set timeframe (typically 30 days).

Making Repairs

For violations found, owners must make the necessary repairs or corrections. This may involve upgrades like installing handrails, replacing old wiring, removing mold, or other fixes. All violations must be addressed before their compliance deadline.

Following Up

After completing repairs, owners can contact the city to schedule a re-inspection to clear any outstanding violations once issues are fixed. Fines apply if violations remain unaddressed past compliance deadlines.

Passing Inspection

If all goes well, the building will pass its inspection once any previous deficiencies get properly corrected. No news is good news when it comes to Chicago inspections!
