Lead Service Line Replacement Ordinance
Cicero
Cook County
In February 2020, the Town of Cicero adopted an ordinance requiring lead service line replacement during major renovations, extended vacancies, and other significant property changes.
Background
Cicero leaders saw a need to address public health issues related to lead service lines and also comply with state-mandated targets. Challenges with speculative real estate activity informed the Town’s approach. Through its vacant building registration program and property transfer process, staff identified patterns of long water shutoffs and property flipping — key moments when lead line replacement could be mandated. After about a year of discussion, the Town’s ordinance was adopted on February 11, 2020.
How It Works
The ordinance requires replacement of lead service lines when:
- A residential property is demolished and rebuilt.
- Renovations equal or exceed 50% of the building’s assessed value.
- Habitable space is increased (e.g., bedrooms, bathrooms).
- Interior water supply lines are changed beyond minor repairs.
- A residential building has been vacant for three or more months.
Initially, real estate agents and out-of-state buyers pushed back strongly. Within two months, resistance subsided, and realtors began advertising homes with copper service lines as a selling point for prospective buyers. Importantly, Cicero did not observe a decline in building permits or property transfers as a result of the ordinance.
To accelerate progress, Cicero is now supplementing private efforts by directly replacing lead service lines through grants awarded by the Illinois Department of Public Health.
Public Involvement
Public engagement prior to adoption was limited. Following adoption, the Town primarily relied on word-of-mouth promotion and shared ordinance details directly with realtors visiting Town Hall. Town leaders later reflected that greater public outreach – such as public discussions and information about the reason behind the ordinance and the positive benefits it would generate – could have reduced initial resistance.
Goal
Replacing as many lead service lines as possible with limited municipal resources.
Target
Homes receiving significant investment from major renovations and house flipping.
Financing
The ordinance applies to property owners. No public financing is involved.
Success
As of July 2025, 800+ homes have had lead service lines replaced as a result of the ordinance.
Lessons Learned
Large-scale replacements could have been made following the 2008 housing market crash, when widespread vacancies presented unique opportunities. Private property owners are often able to complete replacements at a lower cost due to fewer procedural requirements.
