Swansea IL Real Estate: Homes, Schools, and Local Guide

Swansea is a village of about 14,710 people with the highest owner-occupancy rate in this part of St. Clair County and a genuinely mixed housing stock. It also has two things a buyer needs to check early: which of four school districts the address is in, and whether the parcel sits in the regulatory floodplain.

About Swansea, Illinois

Swansea has a population of about 14,710 and roughly 6,175 housing units. Owner-occupancy is 73.4%, the highest of the neighboring communities, and the village publishes that 43.9% of residents 25 and older hold a bachelor’s degree or higher.

The Swansea MetroLink station at 236 Metro Way has 716 parking spaces, and the village actively markets development sites around it. Unlike most of its neighbors, Swansea’s housing is not dominated by one era: 36.6% of homes were built in 2000 or later, while 24.6% were built before 1960.

Buying a Home in Swansea, IL

Swansea rewards buyers who do their homework, because two houses on opposite sides of the village can differ by forty years of construction and by two entirely different school districts.

What to weigh before you make an offer in Swansea:

• Pull the FEMA flood map for the specific parcel. The village itself identifies regulatory floodplain along Wolf Branch and Richland Creek. More below.
• Four PK-8 districts serve this one village. Verify by address, not by which street looks closest to which school.
• The housing stock is genuinely mixed. A quarter of homes predate 1960 and over a third were built since 2000, so inspection expectations should match the specific house, not the town.
• Owner-occupancy is high at 73.4%, which tends to mean settled streets and fewer rentals than neighboring communities.
• Transit-oriented development is an active village priority around the MetroLink station, with published TIF districts and incentives.

Schools in Swansea, IL

The Village of Swansea publishes its own list, and it confirms that this one village is served by four separate PK-8 districts, all feeding a single high school district. Two of those districts’ named schools are physically in Belleville, not Swansea.

The four PK-8 districts serving Swansea addresses:

• Wolf Branch School District 113: Wolf Branch Elementary (PK-4) at 125 Huntwood Road and Wolf Branch Middle (5-8) at 410 Huntwood Road, both in Swansea
• High Mount School District 116: High Mount School at 1721 Boul Avenue in Swansea, a single building covering PK through 8
• Whiteside School District 115: Whiteside Elementary on Lebanon Avenue and Whiteside Middle on Warrior Way, both in Belleville
• Belleville School District 118: the village specifically names Franklin Elementary at 301 North 2nd Street in Belleville

High school:

• Belleville Township High School District 201, which operates Belleville East and Belleville West

Which of the two Belleville high schools a Swansea student attends is set by District 201’s own attendance boundary. We do not print that split because the district does not publish it in a form we can verify, and guessing it would be worse than saying so. Ask the district with the parcel address.
