A bill for an act providing for the disclosure of lead service lines in real estate disclosures.(See SF 425.)

Iowa Senate Study Bill 1063 (SSB1063) was introduced to require property sellers to disclose the presence of lead service lines in real estate transactions. The bill defined 'lead service lines' and mandated their inclusion in property disclosure statements. SSB1063 was later renumbered as Senate File 425 (SF 425) and eventually replaced by House File 876 (HF 876), which was signed into law on June 6, 2025, with an effective date of January 1, 2026.

Media coverage highlighted the law's potential to enhance public health by ensuring homebuyers are informed about lead service lines, thereby enabling them to take necessary precautions or plan for replacements. The legislation was seen as a proactive step toward addressing lead contamination risks in drinking water.

Some reports noted challenges in implementing the law, such as low response rates to surveys aimed at identifying lead service lines. For instance, as of early 2026, fewer than 25% of Des Moines Water Works customers responded to a survey intended to locate potential lead pipes, raising concerns about the effectiveness of voluntary compliance measures.
