The local numbers

How old the homes are in unincorporated Winnebago County

Housing age in unincorporated Winnebago County is close to the Winnebago County norm. 26.5% of its 3,356 homes predate 1960 and 18% went up in 2000 or later.

55.1% of the 3,079 occupied homes in unincorporated Winnebago County heat mainly with utility gas, and 10.9% with electricity. The Census counts no homes here that heat mainly with wood. So for most households the chimney is a furnace and water heater flue first and a fireplace second, which is why a liner sized for a gas appliance matters as much as a clean firebox.

Outdoor burning in unincorporated Winnebago County has its own rule. Winnebago County Code Sec. 42-3 covers unincorporated areas. Landscape waste burning is banned in unincorporated areas surrounded by, or within a mile of, a city or village that bans it. Fireplace ash goes in a lidded metal can at least 10 feet from the house, per the U.S. Fire Administration, and never on a burn pile with leaves.

The Winnebago County Building Division issues the building permit for Unincorporated Winnebago County. It is at 404 Elm Street, Room 403, Rockford, (815) 319-4350. Its pages do not say whether a chimney rebuild, a new liner or a stove install needs a permit, so call before the work is scheduled.

Local rules

Permits, burning rules and fire service in unincorporated Winnebago County

This page covers the rural parts of the county outside any city or village, and its Census numbers are the summed estimates of the six townships with no city or village mostly inside them (Burritt, Harrison, Laona, Owen, Seward and Shirland). Those townships include the census-designated places Lake Summerset and Westlake Village, which also have their own pages, and a small part of Machesney Park, so the figures overlap. A median year built is not shown because medians cannot be summed. We found no primary-source permit page for Seward or Shirland themselves, and neither is on the County Building Division's list of municipalities served, so call the Building Division at 815-319-4350 to confirm.

Chimney, stove and liner work
County Code Chapter 18 makes it unlawful to alter a structure without a permit. The county pages we read do not name chimney, liner or stove work either way, so call the Building Division at (815) 319-4350 before a rebuild, a new liner or a stove or insert install. source

Ordinance 2016 CO 034 adopts the 2015 IRC at Winnebago County Code Sec. 18-321 with amendments (we did not retrieve the amendment text). That listing looks old next to the statewide baseline that began January 1, 2025, so confirm the edition with the Building Division before designing. source 1 source 2
