What should you check before buying a well-water home near El Dorado Hills?
Before you buy a well-water home in El Dorado Hills, verify five things on the specific parcel: the well-completion record, current well production, a certified-lab water analysis, any shared-well agreement, and your lender's written well requirements. California puts maintenance and water-quality testing on the owner of a private domestic well, so nobody else is monitoring this water for you. The time to find gaps is while your contingencies are still open.
Key Takeaways
- California requires a Well Completion Report to be filed with the Department of Water Resources within 60 days after a well is constructed, altered, or destroyed, so a missing report is a question worth asking.
- State guidance puts maintenance, water-quality testing, and eventual abandonment of a domestic well on the property owner, not on a utility.
- The EPA-backed recommendation to test drinking-water wells annually is a recommendation, not a California mandate, so ask for the actual lab reports, dates, and analytes instead of accepting "it tested fine."
- A yield figure on an old completion report is history, not a guarantee, which is why a current production evaluation matters.
- Lender well requirements are property-specific and vary by loan program, so get them in writing before you order tests.
What records should you pull on an El Dorado Hills well before you make an offer?
Start with the well-completion report, the seller's service history, and any county permit records, all tied to the assessor's parcel number. Tiegen tells buyers to start with the parcel, not the neighborhood. Two properties in El Dorado Hills can sit minutes apart and still differ in water source, well age, and maintenance history.
How do you find the well-completion report?
Anyone constructing, altering, or destroying a water well in California must file a Well Completion Report with the Department of Water Resources within 60 days after the work is done. The report can include the well's location, construction date, intended use, depth, geology, construction details, and reported yield. Under Water Code §13752, copies can be released to government agencies and the public, so you or your consultant can request the report instead of relying on the seller's description. The state's well-record data viewer documentation explains how the records are organized.
Treat the online database as a starting point. DWR's own GIS metadata for well completion reports and its well-completion program page indicate that individual records can contain missing or incorrect values, so check the original report. Confirm it belongs to your parcel, then compare the reported depth, construction, and yield with what the seller tells you today.
What should the seller hand over?
Ask for these in writing, early:
- The exact well location on the property
- Prior service invoices and pump information
- Every laboratory water report, with collection dates
- Records of any repair, deepening, replacement, or abandonment
- Any shared-well documents
A licensed well contractor needs a C-57 water-well-drilling license, and the driller is responsible for submitting the completion report. DWR's roles and responsibilities primer for domestic wells spells that out. If a repair invoice comes from someone you can't verify, that's a flag.
Which documents tell you what?
Document | What it tells you | Where to start |
|---|---|---|
Well Completion Report | Depth, construction, intended use, and yield reported at the time of the work | DWR well-completion records, verified against the original report |
Current production evaluation | How the well and pump perform today | Licensed well contractor |
Laboratory water analysis | Water quality on the day it was sampled | Certified laboratory, with chain of custody |
Service and pump records | Repair history and equipment age | Seller and prior service companies |
Shared-well agreement | Ownership, access, cost sharing, and what happens at sale | Seller and title review |
County permit and abandonment records | Original permits, alterations, replacement or sealed wells, correction notices | County environmental health or permitting office, using the parcel number |
How do you test flow, water quality, and equipment before contingencies expire?
Order three separate things: a current production evaluation, an independent water analysis from a certified lab, and a full inspection of the water system by a qualified well contractor. Each answers a different question, and passing one tells you nothing about the others.
How much water flow is enough?
There's no universal California gallons-per-minute number that makes a well "adequate." The right capacity depends on the home, storage, fixtures, irrigation demand, and any lender or local requirement. What you want is a documented evaluation that records the test method, pumping rate, test duration, recovery behavior, static and pumping water levels, pressure-tank performance, and any sign of seasonal decline. A yield figure from the original drilling is a historical data point, not a promise about this year.
Be honest with yourself about your own demand. A buyer planning a large landscape, a pool, or a guest house needs a different answer than one planning a modest lot. That's a conversation Tiegen has with clients before they ever write an offer.
What should a water test include?
Use a certified laboratory and choose the scope based on the property's geology, well construction, nearby land uses, and local environmental-health guidance. Keep the complete report and the chain of custody, not just the seller's statement that the water "tested fine." DWR's Be Well Prepared guidance notes that the EPA recommends annual testing of drinking-water wells. That's a recommendation, and the state's domestic well primer makes clear that testing is the owner's job. Private wells don't come with the consumer reports a municipal customer gets.
One more point: a clean water test and a strong flow test are different results. A well can pass a quality panel and still struggle to keep up with the house, or produce plenty of water that needs treatment.
What about the rest of the water system?
A qualified well contractor should look at the casing, sanitary seal, wellhead, electrical controls, pump, pressure tank, storage tanks, filtration, and distribution plumbing. Ask whether any treatment system is leased, under warranty, or dependent on ongoing filter, membrane, ultraviolet, or chemical replacement. Those are ongoing costs and obligations you'd inherit.
Also look beyond the active well. DWR's well-record materials warn that improperly constructed or abandoned wells can become a source of groundwater contamination. Walk the property for old well sites, and ask for evidence that any abandoned well was properly sealed.
Tiegen's view is that in a wildfire-aware market like El Dorado County, careful disclosure review and inspection coordination protect buyers from costly surprises. Schedule the well work early enough that the results arrive while you can still act on them. Our El Dorado Hills home-buying timeline and inspection guide shows where these deadlines usually fall.
What about shared wells, permits, and lender requirements in El Dorado Hills?
For a shared well, you need the recorded agreement. For permits, you need the county's records on your parcel. For financing, you need your lender's written well requirements before you spend money on tests.
What should a shared-well agreement cover?
A verbal arrangement with the neighbor is not an adequate substitute for a written, enforceable document. The agreement should identify:
- Who owns the well and the equipment
- Easements and access rights
- Maintenance and repair duties, and how costs are split
- Water-use limits
- Dispute procedures and emergency authority
- Insurance
- What happens when a property sells or a participant stops paying
Confirm the agreement covers your parcel and is recorded or otherwise enforceable. Have it reviewed through title, and bring in a real estate attorney if it's missing, unclear, or contested. Also ask for the operating history: past repairs, past disputes, and who has actually been paying.
What if the well has no permit or no completion report?
Don't assume it's fine, and don't assume it's fatal. California's statewide filing rule does not replace local permitting and inspection requirements, so contact the county's environmental health or permitting office with the parcel number. Ask about the original permit, alterations, repairs, replacement wells, abandonment records, and any violation or correction notices. Confirm directly with the county how its process works and what it requires, rather than relying on general assumptions. If the records conflict or can't be found, get written clarification from the county and a licensed well professional before your contingencies expire.
Will your lender care about the well?
Often, yes. Lenders can set property-specific requirements for potable water, well production, water-quality results, shared-well documentation, access, and appraisal conditions, and these can differ by loan program and underwriting file. Ask your lender for its well-water requirements in writing before ordering tests, so you pay for the right scope once. If you're moving from out of the area, the El Dorado Hills relocation checklist and the guide on touring El Dorado Hills before you buy from the Bay Area can help you sequence this work.
Who pays for the tests, and what's required versus prudent?
Who pays for flow and water-quality testing during escrow is a matter of negotiation and your purchase contract, so confirm it in your own contract. In practice, buyers usually order investigations they want done during their investigation period. The only way to know your deadlines is to read the contract's inspection, investigation, title, and loan-contingency terms. Don't assume well issues can be sorted out after closing.
Here's how to think about the split. The completion report filing, local permitting, and any lender conditions are the documented requirements. Production testing, a broad lab panel, a full system inspection, and a shared-well legal review are prudent diligence that protects you whether or not anyone demands them. Your exact scope depends on the parcel, and that's the kind of property-specific review Tiegen walks clients through before they commit.
If you're weighing a well-water home near El Dorado Hills, the core move is the same every time: verify the parcel's records, test the well's output and water quality yourself, and get lender and county answers in writing while you still have contingencies. Tiegen coordinates that process end to end so nothing surfaces after you've removed protections.

FAQ
How do I find the well-completion report for a home in El Dorado Hills?
Search the Department of Water Resources' well-completion records by the property's location, then confirm the report matches your parcel. DWR cautions that database fields can be missing or wrong, so ask for the original report and compare it with the seller's records and the county's permit file.
What should a private-well water test include before I buy?
Use a certified laboratory and choose the panel based on the property's geology, well construction, and nearby land uses, ideally with local environmental-health input. Keep the full report and chain of custody. No single mandatory panel for every private domestic well was identified, so ask your lender and the lab what's appropriate for your file.
Can a well test pass if the well still has low production?
Yes, because water quality and water quantity are separate measurements. A well can meet a lab's quality results and still struggle to supply the home, especially with irrigation or seasonal decline. That's why a current production evaluation is its own step.
What records should I request for a shared well?
Ask for the recorded shared-well agreement, plus the operating and repair history. It should cover ownership, easements, maintenance duties, cost sharing, use limits, dispute procedures, and what happens at sale or nonpayment. Have title review it, and consult a real estate attorney if anything is missing or unclear.
Will a lender require a well inspection or water test?
It can. Lender requirements are property-specific and vary by loan program, covering potable water, production, water quality, and shared-well documentation. Ask for them in writing before you order any testing.
