Court Rules Developer Must Refund 1200 Yuan Water Meter Fee Plus Interest for Unjust Enrichment

Case Overview
A Chinese civil court ruled that a real estate developer must refund 1200 yuan collected from homeowners for water meter installation, plus interest, finding the charge constituted unjust enrichment. The court determined the developer had improperly passed on costs that should have been included in the original housing price.

Case Background and Facts
In 2002, Mr. Li and Ms. Li purchased an affordable housing unit from a development company in Eastern China. The property was part of a subsidized housing project known as an economic适用 housing development. When the buyers took possession of their apartment in April 2003, the developer charged them 1200 yuan under the label of water meter fee collection. The developer issued a special invoice for real estate sales to document this payment.

Seven years later, in 2010, the homeowners learned from community notices that other residents had filed lawsuits challenging similar charges. Upon investigation, they discovered the 1200 yuan fee might have been improperly collected. The homeowners then filed a lawsuit seeking return of the 1200 yuan plus interest calculated from April 2003 to July 2010 at an annual rate of 5.76 percent, totaling 501.12 yuan in interest.

The developer argued that the claim exceeded the two-year statute of limitations. The developer also contended that the fee was justified because the original construction plans did not include the smart metering system later required by municipal policy. According to the developer, the design change added over 1300 yuan per household in costs, and the 1200 yuan fee was simply passed through to cover actual expenses paid to installation contractors and the water company.

Court Proceedings and Evidence
The homeowners presented a sales contract proving their purchase, a property certificate showing ownership, and the invoice documenting the 1200 yuan water meter charge. They also submitted a prior court judgment from a similar case that had found the charge constituted unjust enrichment.

The developer submitted construction drawings showing the original design did not include smart water meters, a government price approval document from December 2001 establishing the base housing price, engineering change orders from December 2001 adding the meters, completion drawings showing the meters were installed, cost verification reports showing actual per-unit costs of 1318.89 yuan, and a cost calculation sheet supporting the 1200 yuan fee.

Both sides agreed on the authenticity of all documents but disputed their relevance. The court accepted all evidence as authentic.

Court Findings and Judgment
The court identified two key issues. First, whether collecting the 1200 yuan water meter fee constituted unjust enrichment. The court held that water supply infrastructure is a basic necessity for normal residential use. Real estate developers have a contractual obligation to provide complete infrastructure. Since the purchase contract contained no special provision about separately charging for water supply facilities, the original housing price was deemed to include all infrastructure costs.

The court noted that the provincial pricing authority had already determined in 2008 that the developer improperly charged the water meter fee outside the approved housing price, effectively raising the price illegally. Based on this, the court found the developer had been unjustly enriched.

Second, regarding the statute of limitations, the court applied the principle that the limitation period for unjust enrichment claims begins when the plaintiff knows or should know about the unjust enrichment and the responsible party. The developer failed to prove the homeowners knew or should have known the fee was improper when it was collected in 2003. The court accepted the homeowners claim that they only learned of the unjust enrichment in 2010 when prior case notices were posted in the community. Therefore, the 2010 lawsuit was timely.

The court ordered the developer to refund the 1200 yuan within ten days and pay interest at 5.76 percent annually from April 20, 2003 until the date of payment. Court costs of 25 yuan were assessed against the developer.

Key Legal Principles
The court applied the principle that unjust enrichment occurs when a party obtains a benefit without legal basis, causing loss to another party. Real estate developers cannot charge buyers separately for basic infrastructure costs that should be included in the contract price. The statute of limitations for unjust enrichment claims runs from when the plaintiff actually discovers the unjust enrichment, not from the date of payment.

Practical Insights
This case demonstrates that homeowners can challenge improper fees collected by developers even years after the transaction. Government pricing authority determinations can serve as strong evidence in civil litigation. Buyers should carefully review all charges at closing and question any fees outside the contract price. Courts will examine whether developers have improperly shifted construction costs to buyers after government price approvals.
