The local numbers
How old the homes are in Rockton
Rockton has more new housing than the county as a whole. 41.2% of its 3,063 homes were built in 2000 or later, against 13.6% county-wide, for a median year built of 1996. Only two of the 13 Winnebago County communities have a higher share of homes built since 2000. Only 23.2% predate 1980 (county: 63.4%), so the permit and code rules below matter more here than the age of the foundation.
Of 2,910 households in Rockton, 81% own their home. The county figure is 65.9%. 73.3% of housing units are single-family detached houses (county: 70.4%).
Permits here run through the Winnebago County Building Division, not a city or village desk. It is at 404 Elm Street, Room 403, Rockford, (815) 319-4350. Its posted schedule values a finished basement at a set rate per square foot and charges a processing fee per trade; the schedule is undated, so confirm any dollar figure with the office. The county's codes page lists the 2015 International Residential Code, so confirm the edition with the Building Division.
Radon belongs on the checklist. IEMA says to retest if renovations or additions are made, and that homes with elevated levels have been found throughout the state. In Rockton, with 3,063 homes, that includes a basement you have just closed in with drywall.

- Code edition
- The County Building Division's codes apply: its codes page (last modified February 20, 2025) lists the 2015 International Residential Code, which looks old next to the statewide baseline that began January 1, 2025, so confirm the edition. Rockton's own municipal code, section 150.01, still lists 1990s model codes (BOCA 1996, CABO 1995), so do not treat it as the current rule. source 1 source 2
