Living Below the Surface: Why Chicago Basement Apartments Face Unique Drainage Challenges That Require Expert Maintenance
Chicago’s basement apartments offer affordable housing options in a city where every square foot counts, but these below-grade living spaces come with specialized drainage requirements that can make or break your comfort and safety. Location and elevation can strongly influence the viability and ease of creating a dry basement unit, given Chicago’s marshland history. While different soil engineering strategies can divert water and affect drainage, sitting at a low elevation in any of these areas suggests that a project may require more intensive foundation drainage and/or waterproofing work.
The Unique Challenges of Below-Grade Living
Unlike ground-level apartments, basement units face constant hydrostatic pressure from surrounding soil and groundwater. A basement may be used for habitable rooms or a dwelling unit, regardless of the depth of the floor below grade, if the floors and walls are impervious to leakage of underground and surface water and are protected from dampness. This creates a perfect storm for drainage issues that require specialized attention.
Chicago’s geography compounds these challenges. Today, an estimated 42% of Cook County is impervious surface, meaning water from Chicago’s recent record-breaking storms cannot be absorbed. As a result, basement flooding and stormwater management has become a huge issue in Chicago, and for our Chicago bungalows. The city’s aging infrastructure adds another layer of complexity, as the Department of Water Management’s flood control efforts deal with drainage systems that are more than 100 years old. Factor in these additional problems, and you have a perfect storm for basement flooding in Chicagoland.
Sump Pump Systems: Your First Line of Defense
For basement apartments, sump pumps aren’t just recommended—they’re essential. A basement sump pump sits at the lowest point of your house in a pit that fills as moisture enters the building. When the water level rises, a float switches it on, and the unit pumps the liquid out of your home through a discharge pipe. Here in the Chicago area, sump pumps are essential to the protection of basements from water incursion.
However, sump pumps require regular maintenance to function properly. One way to avoid an unexpected repair is to perform regular testing and maintenance on your sump pump. If not, it’s much better to find out during a test than during a heavy rainstorm. Test your sump pump regularly (especially before rainy seasons) to ensure it’s working correctly. Clean the pit of debris that can clog the intake. Consider professional maintenance annually.
Battery backup systems are particularly crucial for basement apartments. You can purchase a sump pump with a battery backup. These will typically provide enough power for five to seven hours of continuous pumping or one to three days of intermittent pumping.
Floor Drain Maintenance: The Often-Overlooked Component
Floor drains in basement apartments serve as critical overflow protection, but they require specialized attention. According to Chicago plumbing code, any floor drain or drain trap installed below a basement floor or underground shall be no less than 3 inches (76 mm) in diameter. Floor drains shall connect into traps, shall be accessible and readily cleaned, and shall be located so that they are easily visible.
These drains face unique challenges in below-grade environments. Floor drain traps shall have removable strainers. The floor drain shall be constructed so that the drain is capable of being cleaned. Regular maintenance is essential because foundation and floor drains are in good repair and clog-free. Regularly test the sump pump to make sure it’s operating properly.
One critical issue in basement apartments is trap seal maintenance. Floor drain seals subject to evaporation shall be of the deep seal type, shall be fed by means of a priming device designed for that purpose, or shall be filled with vegetable oil. When trap seals dry out, they can allow sewer gases to enter the living space, creating health hazards.

Warning Signs That Demand Immediate Attention
Basement apartment residents should watch for specific warning signs that indicate drainage system problems. These include water backing up through floor drains, unusual odors emanating from drain openings, and visible water stains around drain areas. Certain questions need to be answered to dispatch a sewer crew: the address location, whether the water is dirty or clean, where the water is coming from (floor drain, toilet, shower etc.), how many inches of water have backed up and whether this is a basement, crawl space or ground level.
Prevention: The Best Medicine
The most effective approach to basement apartment drainage is prevention. While performing your own inspections and maintenance can help prolong the life of your sump pump, it is advisable to have one of our certified plumbers conduct a quick inspection or service on an annual basis. By proactively tackling these actions, you can lessen the risk of the sump pump failing, limiting any issues, while ensuring your basement remains dry, safe and well protected.
Regular professional maintenance should include hydro jetting to clear accumulated debris, inspection of sump pump float switches and discharge lines, testing of backup power systems, and verification that floor drain traps maintain proper water seals. This comprehensive approach ensures that your below-grade living space remains safe, dry, and comfortable year-round.
Living in a Chicago basement apartment doesn’t have to mean constant worry about water intrusion. With proper maintenance, professional support, and understanding of your drainage system’s unique requirements, you can enjoy all the benefits of below-grade living while staying dry and secure.
