How Long Does Well Drilling Take in California?

Well drilling timelines depend on permitting, scheduling, and site conditions. This guide walks through each stage and the factors that affect how long your project will take.

Site Review

Before drilling, a contractor typically visits the site to assess access, geology, and placement. This may happen during the quote process or as a separate step. Site review helps the driller estimate depth, cost, and timeline. Allow a few days to a week for scheduling the visit, depending on contractor availability.

Permitting

Permit applications are submitted to the county. Review times vary—some counties process permits in a few weeks; others take longer. Your contractor may handle the application. Drilling cannot begin until the permit is approved. Factor permit time into your overall schedule.

Scheduling

Once the permit is approved, the contractor schedules the drilling date. During busy seasons, there may be a wait. Contractors often work on multiple projects and coordinate equipment and crew. Book early to secure your preferred timeframe.

Drilling and Completion

The actual drilling may take 1–3 days for a typical residential well. After drilling, the well is cased, developed (cleaned and tested), and the pump is installed. Each step can add a day or more. Weather delays or unexpected geology can extend the timeline.

Regional and Logistical Factors

Remote sites may require longer mobilization. Narrow roads or steep terrain can limit equipment access. In agricultural regions, drillers may be busiest during certain seasons. Contractors who regularly serve your area will have a better sense of local logistics and typical timelines.

The full project—including site review, permit application, scheduling, drilling, casing, development, and pump installation—can take several weeks to a few months. Permit review times vary by county.
What affects the timeline?
Permit processing time, contractor availability, weather, site access, and well depth all affect the schedule. Peak season (spring and summer) may have longer wait times. Remote or difficult-to-access sites can add mobilization and logistics time.
When is the best time to schedule well drilling?
Scheduling depends on contractor availability and your permit timeline. Some property owners prefer to avoid rainy season for access reasons. Contact contractors early to discuss availability and get on their schedule. See our blog on the best time to drill a well in California for more.
