Who pays an unpaid water bill when you buy a Fallbrook home?

Does the unpaid FPUD bill follow the home?

Escrow is nearing its closing date, and the seller’s final water bill is still open: under Fallbrook Public Utility District rules, that balance follows the property. Once you become the owner, you can become responsible for it.

FPUD tells buyers to make sure the seller paid the final bill because any outstanding balance transfers to the new property owner. The district’s new-customer information explains why: water used at the property is considered a benefit to that property.

Administrative Code Section 12.8 is titled “Water Rates or Service Charges Lien on Property.” It says water charges become a lien against the premises where the water was served. It also makes the present owner responsible for delinquent bills left by former owners or tenants.

So don’t treat the final water bill like an ordinary personal bill that stays with the customer whose name appears on it.

An unpaid balance can still cause trouble after closing. Under Section 12.8, FPUD may shut off water for unpaid charges. Service won’t resume at that property until the delinquency and additional turn-on charges have been paid in full.

If the new owner appeals to the FPUD Board, the owner first has to show that they pursued recovery from the prior owner or the agents involved in the real estate transaction.

What should you settle before closing?

Before closing, you should verify the property’s unpaid FPUD water and sewer charges and request an estimated bill for the closing date. FPUD Customer Service can prepare that estimate when you ask.

As the seller, confirm the final bill instead of assuming someone else has checked it. As the buyer, ask whether the balance has been paid. An estimate gives both sides a specific amount to review while escrow is still open, but it doesn’t replace confirmation that payment was made.

FPUD lists Customer Service at (760) 728-1125. Its office is at 990 E Mission Rd, Fallbrook, CA 92028. You can ask about the outstanding balance and the estimate tied to the planned closing date.

Water and sewer charges are one part of the closing ledger. Sellers can review California home-selling costs for other escrow items. The account check is also separate from what a California seller must disclose. One deals with money owed to the district. The other deals with information about the property.

Before you sign off on the closing figures, ask one simple question: does any unpaid FPUD balance remain attached to this property?

What happens after escrow closes?

After escrow closes, both the buyer and seller should call FPUD so the district can process the account transfer. FPUD will need the buyer’s first and last name from the seller for that transfer.

The timing matters. Check the balance and request the estimated bill before closing, then make the transfer call after escrow closes. That keeps an unpaid charge from surfacing only when you try to move the account into the buyer’s name.

You’ll have other post-closing paperwork, but it doesn’t run through FPUD. A supplemental property tax bill is separate from the water and sewer account. So is the homeowners’ exemption claim.

Why does the backflow questionnaire matter?

The Backflow Questionnaire helps FPUD decide whether the property still needs a backflow device and its monthly maintenance charge. Most of the new-owner packet is yours to keep. The questionnaire is the one item FPUD requires you to send back.

These devices are most common on properties that are agricultural or were agricultural in the past. FPUD also finds them on properties with an auxiliary water supply, such as a well or recycled water system. That means the charge can appear on a home that no longer looks like an agricultural property.

FPUD says every backflow device in its service area is inspected annually under state law. The monthly charge pays the district to inspect and maintain the device, including repairs or replacement when needed. You can read the district’s backflow program requirements, which also point to Administrative Code Section 19.22.

A device isn’t automatically removable just because the property’s use changed. If the property is no longer agricultural and has no auxiliary water supply, you may be able to have the device removed and stop the monthly maintenance charge. Start by completing the Backflow Questionnaire so FPUD can evaluate the property.

Different rules apply when the property uses FPUD’s agricultural water rate. That rate requires a backflow device installed at the meter and an active agricultural area served by that meter.

How is the residential sewer charge calculated?

FPUD bases the residential sewer charge on water used during the winter months. Its customer information identifies December through February, when customers irrigate less. The 2026 rate sheet describes residential billable flow using a two-year winter average.

The district’s materials give different levels of detail, but the point for a buyer is straightforward: winter-month water use affects the sewer charge. Don’t assume the sewer portion of a bill simply tracks the water used during one billing period after closing.

Wastewater service charges apply to every property connected to an FPUD wastewater line, even when the property is unoccupied. Leaving the home vacant doesn’t remove that charge.

For the applicable figures, use the sheet linked from FPUD’s water rates and fees page. The 2026 sheet is headed “Proposed Effective 01/01/2026,” so check the district’s posted material instead of relying on an older copied amount.

Is every Fallbrook address served by FPUD?

No, not every Fallbrook-area address is served by FPUD, so confirm the district for the specific property. Rainbow Municipal Water District serves Rainbow, Bonsall, and portions of Vista, Oceanside, and Fallbrook.

Call FPUD at (760) 728-1125 to confirm which district serves the address. This is especially important when the property may be near a service boundary.

The district determines which transfer instructions you follow. Rainbow asks new owners to submit its transfer form at least seven business days before the scheduled close of escrow. FPUD asks buyers and sellers to call after escrow closes. Rainbow explains its process on its start-service page.

Don’t assume FPUD’s unpaid-balance rule applies to a Rainbow account. That rule is FPUD’s. Identify the correct district first, then use that district’s transfer process.

Did FPUD’s supplier change affect these escrow steps?

No, FPUD’s 2024 wholesale supplier change didn’t alter these buyer and seller account steps. FPUD switched from the San Diego County Water Authority to Eastern Municipal Water District on January 1, 2024, after approval by the Local Agency Formation Commission and an election of FPUD voters.

FPUD describes the wholesaler switch as a paper change in who it pays. The water still comes from Metropolitan through the same pipes and facilities.

The Santa Margarita River Conjunctive Use Project is another part of the supply picture. It began delivering local water to homes in late 2021. FPUD says the project supplies about half of its water and is its cheapest source.

For escrow, your tasks remain the same: check the property balance, request the estimated closing bill, call after closing, and review any backflow charge.

The short version

An unpaid FPUD water or sewer balance can become the buyer’s responsibility because the charge follows the property. Before closing, verify the account balance and ask Customer Service for an estimated bill tied to the closing date.

Confirm that FPUD actually serves the address. If you’re unsure, call FPUD at (760) 728-1125. A property served by Rainbow Municipal Water District follows Rainbow’s transfer instructions instead.

After escrow closes, both sides should call FPUD. The district will need the buyer’s first and last name from the seller for the transfer.

Return the Backflow Questionnaire from the new-owner packet. On a former agricultural property, ask whether the device is still required and whether the monthly maintenance charge applies. If the property is no longer agricultural and has no auxiliary supply, you may be able to have the device removed and stop the fee.

Review the property’s winter water use, too, because FPUD uses winter-month consumption to set the residential sewer charge. For applicable figures, read the district’s posted rate sheet rather than using an older copied amount.
