How Much Does a Semi-Inground Pool Cost in Chicago, IL? [2026 Data]

The average cost for a semi-inground pool in Chicago, IL, is $12,432, with most homeowners paying between $7,252 and $20,720 on typical projects. Illinois sits just above the national price level, so costs in Chicago, IL, trend modestly higher than average once frost-line excavation, permitting, and one of the highest combined sales tax rates in the country are factored in.

Semi-Inground Pool Cost Factors 

Suburban Cook County lots tend to have more room to work with than city lots, which can affect excavation costs. Compact city lots and clay-heavy soil, especially on the South and Southwest Sides, shape how Chicago, IL, pool installers approach a semi-inground build.

Size

The larger your semi-inground pool, the higher the cost, with prices ranging from $7,200 for a 10-foot-diameter pool to $25,600 for a 24-foot-diameter pool. Standard pool types in prefabricated shapes will cost less than those with custom measurements. City lots often push homeowners toward smaller footprints, while North Shore and western suburbs see more 20-foot-plus installations. 

Here’s how semi-inground pool sizes vary in cost:

Materials

The material used for your semi-inground pool will impact the cost, ranging from an average of $3,100 for steel to $22,600 for concrete. Vinyl liner systems and steel-walled kits are commonly used in Chicago, IL, because they can be engineered to perform well in freeze-thaw climates when properly coated and installed, an important factor to consider when putting in a pool here.

Here’s how your semi-inground pool material might affect the cost:

Frost-Line Excavation

The cost of excavation for a semi-inground pool is an important cost factor, just as it is when deciding between an in-ground or above-ground pool. Design standards in Chicago, IL, commonly require structural elements to be installed to a depth of about 42 inches to protect against frost heave. This deeper excavation, along with clay-heavy soil common across the region, can add $700 to $2,500 in extra excavation compared to warmer-climate installations.

Pool Pro Costs

Hiring an experienced pool contractor in Chicago, IL, covers frost-line excavation, licensed plumbing and electrical work, and any required city or county permitting.

Labor

Chicago, IL, pool contractors charge $55 to $150 per hour, with labor representing roughly 25% to 50% of the total project cost. For a typical semi-inground project, combined labor across excavation, plumbing, and electrical runs $3,100 to $6,200.

Permits

Most semi-inground pool projects require a combination of building, electrical, and plumbing permits, along with zoning review where applicable. Permit costs range from $200 to $1,000 or more, depending on jurisdiction, project scope, and site conditions.

Additional Pros to Consider Hiring 

Beyond the core pool builder, homeowners often bring in a drainage specialist for clay-heavy lots, a licensed electrician for bonding and GFCI protection, and a fencing contractor. Barrier requirements are set by local municipalities and counties rather than a single statewide rule across Illinois.

Does a Semi-Inground Pool Increase Home Value?

Data suggests homeowners in Chicago, IL, can expect around a 7% increase in home value for an in-ground pool on average, with some projects reaching up to 55% of installation cost recouped at resale. Because of cold winters and a shorter swim season, pool ROI tends to land below what homeowners see in states with year-round warmth.

How Angi Gets Its Local Cost Data 

To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.

Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
