The local numbers
How old the homes are in Rockford
The bathrooms in Rockford sit in some of the oldest houses in the county. 22.4% of its 67,423 homes were built before 1940 (county: 15.5%) and 46.5% before 1960, with a median year built of 1963. Only one of the 13 Winnebago County communities has a higher share of pre-1940 homes. In a house that age the bathroom is usually small and has been redone at least once already, so a remodel often starts with finding out what is under the last layer of tile. See the small bathroom page for what that size of room costs.
74.3% of Rockford's homes were built before 1980 (county: 63.4%). The EPA's cutoff is 1978, so most of those houses fall under its lead-safe work rule: anyone paid to tear out a painted wall or window in them must be certified. Ask for the certificate before demolition starts.
33,697 of the 61,324 households in Rockford own their home, and 35.2% of those owners are 65 or older (county: 34.7%). That is the household that asks about a low-curb shower, grab bars and a comfort-height toilet; the accessible bathroom page covers the prices, and Illinois gives buyers 65 and older 15 business days to cancel a contract signed at home with an uninvited salesperson.
The permit office for Rockford is local, not the county. Rockford requires a plumbing permit to "erect, install, enlarge, alter, repair, remove, convert, or replace plumbing systems, equipment, appliances, or fixtures." Replacing a fixture in the same location is exempt as long as no trap or piping has to be resized or rearranged, so a same-spot toilet or faucet swap needs no plumbing permit but moving a toilet, tub or shower drain does. Swapping a receptacle, switch or light fixture is exempt if the wiring and box are not altered, and replacing wall coverings is exempt up to 50% of a room when no framing is exposed.
The city FAQ answers "Can a homeowner install plumbing work in their home?" with "Yes, if they reside in the single family dwelling, otherwise the work must be performed by a licensed plumbing contractor." Electrical work follows the same rule with a city-registered electrician, and general contractors are not licensed.
Who supplies the water matters for glass, fixtures and grout. The City of Rockford Water Division serves the city from municipal wells (about 147,000 people). Its 2025 Consumer Confidence Report does not publish hardness. Our hard water guide covers what that means for a new shower.
Post the permit where it can be seen from the street or at the main entrance before work starts, and request inspections one full business day ahead. Rockford adopted the 2021 IRC with local amendments for permits submitted on or after December 31, 2024, and plumbing follows the Illinois Plumbing Code with local amendments.

Permits, plumbing and water in Rockford
Wikipedia lists Rockford in Winnebago and Ogle counties; the Census figures on this page cover the whole city.
- Bathroom work and permits
- Rockford requires a plumbing permit to "erect, install, enlarge, alter, repair, remove, convert, or replace plumbing systems, equipment, appliances, or fixtures." Replacing a fixture in the same location is exempt as long as no trap or piping has to be resized or rearranged, so a same-spot toilet or faucet swap needs no plumbing permit but moving a toilet, tub or shower drain does. Swapping a receptacle, switch or light fixture is exempt if the wiring and box are not altered, and replacing wall coverings is exempt up to 50% of a room when no framing is exposed. source 1 source 2 source 3 source 4
- Permit office
- Permits come from the Community and Economic Development Department, Construction and Development Services, 425 East State Street, (779) 348-7158, or through the Rockford Citizen Portal. A permit is required for the "construction, alteration, enlargement, repair, or moving of a structure larger than 120 square feet." Painting, papering, tiling, carpeting, cabinets and counter tops are exempt, and so is replacing wall or ceiling coverings when 50% or less of the coverings in a room are removed and no framing is exposed to the point where hardwired smoke alarms become required. The permit must be posted visible from the street or at the primary entrance before work starts, and inspections are requested one full business day (24 hours) ahead. source 1 source 2 source 3
- Who may do the plumbing
- The city FAQ answers "Can a homeowner install plumbing work in their home?" with "Yes, if they reside in the single family dwelling, otherwise the work must be performed by a licensed plumbing contractor." Electrical work follows the same rule with a city-registered electrician, and general contractors are not licensed. source 1 source 2 source 3
- Permit fees
- The city fee schedule (an undated PDF) prices alterations and remodels at 0.55% of the total reported value, labor and materials included (minimum $13), plus $56 for each trade permit issued under the building permit, with a 10% technology surcharge. Starting work without a permit doubles the fee, to not less than $274. Confirm the current figures with Construction and Development Services before budgeting. source 1 source 2
- Code edition
- Rockford follows the 2021 ICC code cycle: the 2021 IRC with local amendments took effect January 1, 2025, for permits submitted on or after December 31, 2024. The local amendments we could read change permit exemptions (R105.2) and flood elevation (R322.2.1). Plumbing follows the Illinois Plumbing Code with local amendments, so confirm with the city before relying on the model text. source 1 source 2
- Contractor rules
- The city says "General contractors are not required to be licensed." Roofers need an Illinois state license. Electrical contractors must register with the city each calendar year ($25, or proof of a license or registration from another Illinois municipality). Plumbing permits go to a licensed plumber or to the owner-occupant of a single family home. source 1 source 2 source 3 source 4
- Water supplier
- The City of Rockford Water Division serves the city from municipal wells (about 147,000 people). Its 2025 Consumer Confidence Report does not publish hardness. It lists iron at 0.1 ppm (range 0 to 0.14, state limit 1.0) and manganese at 6 ppb (state limit 150), so rust-colored staining from city water is unlikely; white mineral scale on glass and fixtures is the more common complaint with groundwater, and a home hardness test tells you what yours is. source 1 source 2 source 3
- Also worth knowing
- Post the permit where it can be seen from the street or at the main entrance before work starts, and request inspections one full business day ahead. Rockford adopted the 2021 IRC with local amendments for permits submitted on or after December 31, 2024, and plumbing follows the Illinois Plumbing Code with local amendments. source 1 source 2 source 3
