Homebuyer Wins Refund of 1200 Yuan Water Meter Fee in Unjust Enrichment Case

Homebuyer Wins Refund of 1200 Yuan Water Meter Fee in Unjust Enrichment Case

Case Overview
In a significant consumer protection case from Eastern China, a homeowner successfully sued a real estate development company for unjust enrichment after the company charged an extra 1200 yuan for water meter installation. The court ruled that the developer improperly collected the fee outside the agreed housing price, ordering a full refund plus interest.

Case Background and Facts
Mr. Qian purchased an affordable housing unit from Zhejiang Economic Housing Development and Construction Company in 2003. When the developer handed over the property in April 2003, it charged Mr. Qian 1200 yuan under the label “water meter collection fee.” Mr. Qian paid this amount without immediate objection. In 2010, Mr. Qian learned from other residents that several homeowners had filed lawsuits challenging this charge. After inquiring with property management, he discovered the 1200 yuan fee might constitute unjust enrichment. The developer refused to refund the money, leading Mr. Qian to file a lawsuit in December 2010 seeking the return of 1200 yuan plus interest of 501.12 yuan calculated from April 18, 2003 to July 17, 2010 at an annual rate of 5.76 percent.

The developer defended itself on two main grounds. It argued that Mr. Qian’s claim was barred by the two-year statute of limitations, since the fee was paid in 2003 and the lawsuit was filed in 2010. The developer also claimed the fee was legitimate and not unjust enrichment. It explained that when the provincial pricing bureau approved the housing price in December 2001, the construction plans did not include a centralized smart water meter system. Later, to comply with city policy requiring individual water meters, the developer modified the design, which increased costs by over 1300 yuan per unit. The developer stated it charged only 1200 yuan per household and paid the full amount to contractors and the water company, retaining no profit.

Court Proceedings and Evidence
Mr. Qian submitted several pieces of evidence to support his claim. He presented the housing purchase contract proving his property purchase, the property ownership certificate showing his legal title, and the invoice demonstrating the developer collected 1200 yuan as a water meter fee. He also submitted a court judgment from a related case, which found that the developer’s water meter charge constituted unjust enrichment. The developer challenged the relevance of this judgment but did not dispute the authenticity of Mr. Qian’s documents.

The developer presented its own evidence, including construction drawings showing the original design lacked smart water meters, the pricing approval document from the provincial pricing bureau, engineering change orders showing the design modification, completion drawings confirming the water meters were installed, cost verification reports showing actual expenses of 1318.89 yuan per unit, and a cost calculation table supporting the 1200 yuan fee. Mr. Qian did not dispute the authenticity of these documents but argued they were irrelevant to the unjust enrichment claim.

Court Findings and Judgment
The court identified two main issues for resolution. The first issue was whether the developer’s collection of the 1200 yuan water meter fee constituted unjust enrichment. The court held that water supply facilities are essential infrastructure for habitable housing. A real estate developer has a contractual duty to ensure properties have complete and functional infrastructure. The purchase contract between Mr. Qian and the developer contained no special agreement requiring Mr. Qian to pay extra for water supply facilities beyond the housing price. The developer failed to prove that providing water supply facilities was not part of its contractual obligations. Therefore, the housing price already included the cost of water supply facilities. The court also noted that the provincial pricing bureau had already determined in its 2008 official response that the developer’s water meter fee collection was an unauthorized price increase outside the approved housing price. Based on these findings, the court concluded the developer’s collection of the 1200 yuan fee was indeed unjust enrichment.

The second issue was whether the statute of limitations barred Mr. Qian’s claim. The court applied the legal principle that the limitation period for unjust enrichment claims begins when the party knows or should know of both the unjust enrichment fact and the identity of the benefiting party. The developer could not prove that Mr. Qian knew or should have known the fee was unjust enrichment at the time of payment in 2003. The court accepted Mr. Qian’s statement that he only learned of the unjust enrichment in 2010 when notices about previous successful cases were posted in the residential community. Since Mr. Qian filed his lawsuit in December 2010, the court found the claim was timely.

The court ordered the developer to return the 1200 yuan to Mr. Qian within ten days of the judgment taking effect. It also ordered the developer to pay interest on the 1200 yuan at an annual rate of 5.76 percent from April 19, 2003 until the date of actual payment. The developer was required to bear the court costs of 25 yuan.

Key Legal Principles
The court applied two fundamental legal provisions. Article 92 of the General Principles of the Civil Law states that obtaining improper benefits without a legal basis causes unjust enrichment, and the benefited party must return the benefits to the injured party. Article 131 of the Supreme Peoples Court Opinions on Implementing the General Principles of the Civil Law provides that the returned unjust enrichment should include the original property and any profits derived from it.

Practical Insights
This case demonstrates that homebuyers can successfully challenge unauthorized fees charged by developers after property purchase. The court clarified that essential infrastructure costs, such as water supply facilities, are generally included in the housing price unless the contract specifically states otherwise. The case also highlights that the statute of limitations for unjust enrichment claims begins when the victim actually discovers the improper charge, not when the payment was made. Homeowners should be aware that official determinations by pricing authorities can serve as strong evidence in such disputes.
