While California doesn't legally mandate well inspections before sale, most buyers and lenders require them. A professional well inspection can identify issues before they derail your sale and provides documentation that protects you as a seller. Most real estate transactions involving private wells include inspection contingencies.
California requires sellers to disclose known material facts about the property's water source, including: that the home uses a private well (not municipal water), any known well problems or repairs, water quality issues you're aware of, well age if known, shared well agreements, and any permits or violations. These are typically disclosed on the Transfer Disclosure Statement (TDS) and Seller Property Questionnaire (SPQ).
Lenders typically require testing for coliform bacteria, nitrates, and sometimes nitrites. FHA and VA loans have specific requirements. Many buyers also request tests for pH, hardness, iron, manganese, and total dissolved solids. In agricultural areas, arsenic testing is often requested. Testing typically costs $150-$500 depending on the panel.
Yes, significant well problems can derail a sale. Common deal-breakers include failed water quality tests (especially bacteria), inadequate water flow (low GPM), unpermitted wells, wells that don't meet current setback requirements, and major equipment failures. However, many issues can be resolved with proper treatment, repairs, or price adjustments.
A basic well inspection costs $200-$400 and includes pump performance testing, pressure system evaluation, and visual inspection. Comprehensive inspections with water testing range from $400-$800. Video camera inspections for well casing condition cost an additional $300-$600. Many sellers opt for comprehensive inspections to avoid surprises.
This is negotiable. In California, buyers often pay for inspections as part of their due diligence. However, some sellers opt to pre-inspect to identify and address issues before listing. Who pays for repairs is also negotiable and often split or credited through price adjustments.
If coliform bacteria is detected, the well typically needs shock chlorination (cost: $200-$400) followed by re-testing. Most sales proceed after successful treatment. If bacteria persists, the well may need repairs to address the contamination source, or a UV treatment system may be installed. Buyers may request credits or repairs as a condition of proceeding.
Yes, both FHA and VA loans have specific requirements. Wells must meet local codes and setback requirements, water must test safe for coliform and nitrates, the well must provide adequate water supply, and proper documentation must exist. FHA specifically requires wells to be at least 50 feet from septic tanks and 100 feet from septic drain fields.
