Can You Drill a Well Anywhere? Permits & Location Rules
Owning property doesn't automatically mean you can drill a well wherever you want. California has setback requirements, permit processes, and zoning rules that determine where wells can be located. Understanding these requirements before you start planning saves time, money, and potential legal issues.

This guide covers California well drilling regulations, setback distances from contamination sources, the permit process, and factors that determine the best location for your well.

California State Requirements
All water well drilling in California requires:
- Well permit from local enforcement agency (usually county environmental health)
- Licensed C-57 well drilling contractor
- Well completion report filed with state
- Compliance with California Well Standards (Bulletin 74-81 and 74-90)
County Permit Process
San Diego County:
- Permit through Department of Environmental Health
- Fee: $500-1,000+ depending on well type
- Site inspection may be required
- Typically 2-4 weeks processing
Riverside County:
- Environmental Health Department
- Similar fee structure to San Diego
- May require additional review in some areas
Drilling Without Permit
Don't do it. Consequences include:
- Fines up to $25,000 per day of violation
- Required destruction of non-permitted well
- Liability for any contamination
- Title issues when selling property
- No legal recourse if problems occur
Setback Requirements
California requires minimum distances between wells and potential contamination sources:
Standard California Setbacks
| Feature | Minimum Distance |
|---|---|
| Septic tank | 50-100 feet |
| Leach field/drain field | 100 feet |
| Sewer lines | 50 feet |
| Animal enclosures | 50-100 feet |
| Property lines | Varies by county (often 5-50 feet) |
| Buildings | 5-10 feet (for drilling access) |
| Surface water | 50 feet |
| Flood zones | Special requirements |
Local Variations
Counties may have stricter requirements:
- San Diego County often requires 100 feet from septic
- Some areas require 50 feet from property lines
- Groundwater protection zones may have additional rules
Setback Challenges
On smaller properties, meeting all setbacks can be difficult:
- May limit viable drilling locations
- Could require variance (rarely granted)
- Some properties simply can't accommodate a well
Restrictions Beyond Setbacks
Adjudicated Groundwater Basins
Some areas have court-ordered water allocation:
- May limit or prohibit new wells
- Require purchase of water rights
- Subject to pumping restrictions
Check with your county or water agency if you're in a managed basin.
Sustainable Groundwater Management Act (SGMA)
California's SGMA may affect new wells in:
- Medium and high-priority basins
- Critically overdrafted basins
- Areas implementing Groundwater Sustainability Plans
Zoning and Land Use
- Some zones may restrict well use (domestic only vs. agricultural)
- HOAs may have covenants against wells
- Historic districts may have additional review
Environmental Restrictions
- Endangered species habitat
- Wetlands
- Vernal pools
- Archaeological sensitive areas
Easements
- Utility easements may prohibit drilling
- Access easements may limit locations
- Check title report before planning
Site Selection Factors
Rig Access
Drilling rigs are large vehicles:
- Need 12+ feet width, 40+ feet length
- 20+ feet overhead clearance
- Stable, relatively flat surface
- Access for water truck and support vehicles
Water Table Location
- Research neighboring well logs (county records)
- Understand local geology
- Consider depth estimates for budgeting
Future Development
Consider where you might:
- Install future septic (setback requirements)
- Add structures
- Create animal areas
Topography
- Avoid low areas where runoff collects
- Consider flooding potential
- Steep slopes require special techniques
Wells With Municipal Water
Supplemental Wells
Many properties have both well and city water:
- Well for irrigation, washing, outdoor use
- Municipal water for drinking
- Saves money on water bills
Requirements
- Backflow prevention: Required to prevent well water from entering municipal system
- Separate plumbing: Well and municipal systems cannot be cross-connected
- Permit still required: Even for irrigation-only wells
Water District Rules
- Some districts have notification requirements
- May charge fees for secondary water source
- Check with your provider before drilling
The Permit Process
Typical Steps
- Site evaluation: Driller assesses property, identifies viable locations
- Application: Submit permit application with site plan
- Review: County reviews setbacks, zoning, any restrictions
- Approval: Permit issued (2-6 weeks typical)
- Drilling: Work must begin within permit validity period
- Inspection: Some counties inspect during or after drilling
- Completion report: Filed with state within 60 days
Your Driller Should Handle
Reputable contractors typically:
- Prepare and submit permit applications
- Create required site plans
- Coordinate inspections
- File completion reports
This is part of their service—you shouldn't need to navigate the bureaucracy yourself.
Frequently Asked Questions
Do I need a permit to drill a well in California?
Yes. California requires permits for all water well drilling. You'll need a well permit from the county environmental health department (or equivalent local enforcing agency). Fees range from $300-1,500 depending on county and well type. Your drilling contractor typically handles the permit application process as part of their services.
What are the setback requirements for wells?
California has minimum setbacks from potential contamination sources: typically 100 feet from septic tanks and leach fields, 50 feet from sewers and animal enclosures, and various distances from property lines (often 5-50 feet depending on county). Local requirements may be stricter than state minimums—always verify with your county.
Can I drill a well on any property I own?
Owning property doesn't automatically guarantee drilling rights. Restrictions may include: utility easements, HOA covenants, adjudicated groundwater basins requiring water rights, endangered species habitat, slope limitations, flood zones, and inadequate space to meet setback requirements. In some areas, water rights may be separate from land ownership.
Can I drill a well if I'm connected to city water?
Usually yes, but with requirements. Many areas allow supplemental wells for irrigation while maintaining municipal connection for drinking water. Cross-connection prevention (backflow preventer) is typically required to prevent well water from entering the municipal system. Some water districts have additional rules or notification requirements—check with your provider.
How close to my septic can I drill?
California generally requires at least 100 feet from septic leach fields and 50-100 feet from septic tanks. These are minimum distances—more is better. On small properties, this can be the limiting factor in whether a well is feasible at all.
What happens if I drill without a permit?
Drilling without a permit in California can result in fines up to $25,000 per day, required destruction of the well at your expense, liability for any contamination, title issues when selling property, and no legal recourse if the well has problems. It's not worth the risk—permits exist to protect your water and your neighbors'.
Site Assessment & Permit Assistance
Southern California Well Service evaluates drilling feasibility, identifies the best well location, and handles the permit process for properties throughout San Diego, Riverside, and San Bernardino counties.
