Off-Grid Living in Kern County, California

I surveyed Kern County's off-grid rules by reviewing county public health and public works guidance, California state building and water law, and contacted or reviewed documents from the Public Health Department and Public Works Development Services. What I found is that Kern County does not operate a single unified off-grid code. Instead, regulatory authority is fragmented: incorporated cities - Bakersfield, Delano, McFarland, Shafter, Wasco, and others - each set their own zoning and building rules within their boundaries, while unincorporated areas follow county guidelines that are minimal and sector-specific rather than comprehensive. Understanding off-grid feasibility here requires first confirming which jurisdiction governs your property, then working through each of the eight domains in sequence.

Zoning and Lot Size: Varies by Municipality

Kern County does not publish a single countywide zoning code that I could confirm through county planning or public documents. Instead, minimum lot sizes, land-use classifications, and permitted uses are set by your city or by the unincorporated-county planning authority where your parcel sits. If you own land in unincorporated Kern County, the Kern County Planning & Natural Resources Division manages zoning; if your land is within a city, that city's planning department controls zoning and use restrictions.

The practical step: First, determine whether your property address is in incorporated or unincorporated Kern County. The Kern County Assessor's website or a quick call to the Planning & Natural Resources Division (559-445-2020 or similar) can confirm this. If you are unincorporated, ask the planning staff whether your parcel is zoned agricultural, rural-residential, or another category, and whether single-family residential and agricultural uses are permitted on the minimum lot size. If you are in a city, contact that city's planning department directly. Bring your legal description (township, range, section) and a map showing where you intend to build. Be prepared to explain that you plan off-grid systems (well, septic, solar); planners will tell you whether your zone permits it.

Dwelling Type and Size: No County-Level Restrictions

Kern County guidelines do not specify restrictions on dwelling size, tiny homes, RVs, or alternative housing types at the county level. California's Building Code does define tiny homes (see below), and state law limits RV occupancy to 180 days per year unless they are on a property with a permanent foundation, but Kern County itself does not impose additional dwelling-type rules that I could confirm.

This means your options depend entirely on your city or unincorporated-area zoning. A city may allow only site-built homes, or may permit ADUs (accessory dwelling units), or may explicitly allow RVs if they meet California standards. Unincorporated Kern County likely has similar variability. The practical sequence is to confirm zoning first (see above), then ask your planning department whether tiny homes, RVs on permanent foundations, or prefabricated structures are permitted in your zone. If tiny homes or alternative structures interest you, ask whether they must comply with Title 24 (California Building Code) and whether any local amendments apply.

Building Permits and California Building Standards

California's Title 24 Building Standards Code applies statewide and covers structural safety, sanitation, energy efficiency, and fire resistance. Each county administers Title 24 through its building department, but can adopt local amendments and stricter standards. Kern County does not publish a single countywide building code I could confirm; instead, each city and the unincorporated area likely have their own adopting ordinances.

The practical implication is that almost any building in Kern County - whether an off-grid home, a solar array structure, or an outbuilding - will require a building permit reviewed against Title 24. If your property is unincorporated, contact Kern County Public Works Development Services (which handles building inspections for unincorporated areas). If you are in a city, contact that city's building department. Expect to submit plans showing structural design, electrical layout (even if off-grid, solar systems must be permitted), plumbing (including septic connections), HVAC, and fire-safety features. An unconventional design - say, a rammed-earth or straw-bale home - will require an engineer's stamp and may face scrutiny; permitted, conventional construction (wood framing, ICF, etc.) is faster. Budget for plan review (typically several weeks) and inspections at framing, rough-in, and final stages.

Septic Systems: Permitted but Compost Toilets Prohibited

This is Kern County's clearest off-grid rule. The county permits individual on-site septic tanks through the Public Works Department, which requires a site plan approval and percolation testing. However, compost toilets are prohibited - a crucial distinction. You cannot use a compost toilet as your sole sanitary facility in Kern County, even if you own 10 acres. This is stricter than the California state baseline (which allows composting toilets as a supplement to a permitted system) and reflects Kern County's ground-water protection standards.

The minimum lot size for a property with both a well and a septic system is 1 acre net (that is, usable area, excluding slopes and wetlands). Setback distances are mandatory: your well must be at least a certain distance from your septic tank, leach field, seepage pit, storm drains, sanitary sewer lines, and property lines - exact distances are set by Kern County Public Health and typically range from 50 to 100 feet depending on soil type and system design. Kern County Public Health oversees septic and well approvals; Public Works handles the site-plan review.

The practical sequence: Contact Kern County Public Health (661-868-0201 or via kernpublichealth.com) and request a septic system application. You will need a legal description, a site plan showing the proposed septic tank and leach field locations, your proposed well location, and the distance between them. Public Health will direct you to conduct a percolation test (a soil infiltration test that determines the septic system design). This test costs $300-800 and must be done by a licensed contractor. Once the perc test is completed, you can propose a septic tank size and design. Public Health will approve or request modifications. You then hire a licensed installer to construct the system and obtain a final inspection. Do not assume that a 1-acre lot is large enough in practice; if soil percolation is poor, you may need a larger dispersal area or a more expensive aerobic or pressure-dosed system. Allow 6-12 weeks for approval.

Wells: Permitted with Setback Requirements

Private wells are permitted in Kern County and require approval through the Public Works Department. You must submit a site plan showing the proposed well location and its distance from septic systems, storm drains, sewer lines, and property lines. The well must be drilled by a California-licensed well contractor (not a handyman) and must meet California Well Standards, including casing, grouting, and disinfection. Once drilled, the water must be tested for drinking-quality standards (bacteria, nitrate, and other parameters set by California's Department of Water Resources and the county).

An important caveat: Kern County lies in the Southern San Joaquin Valley, an area with significant groundwater depletion and subsidence. Your ability to pump a well long-term depends on whether the groundwater basin underlying your parcel is managed by a Groundwater Sustainability Agency (GSA) under California's Sustainable Groundwater Management Act (SGMA). Many Kern County parcels fall under SGMA basins with pumping limits or fees. Before buying or drilling, verify with the Kern County Water Agency whether your parcel is subject to groundwater-management restrictions. This is not typically enforced at the time of drilling but may affect your long-term water rights.

The practical sequence: Contact Kern County Public Works Development Services (559-445-2020, ext. development) and request a well-permit application. Provide your site plan with proposed well location, distance from septic systems, and legal description. Once approved, hire a licensed well driller (typically $2,500-5,000 for a 100-200-foot well in unincorporated Kern County). After drilling and disinfection, arrange water testing through the county or a certified lab. Public Works will issue a final permit once the well is tested and documented. Verify groundwater availability and SGMA restrictions before drilling; this can be confirmed at the Kern County Water Agency (559-445-2020) or by contacting your local GSA.

Greywater Reuse: California Permits It; Kern County Does Not Address It

California's Plumbing Code permits laundry-to-landscape greywater systems in single-family homes without a permit if thirteen specified guidelines are followed (for example, the system must use gravity or a simple drip system, must not pool on the surface, and must irrigate non-edible plants only). All other greywater-reuse systems - such as those recycling shower water or from multiple sources - require a permit.

Kern County does not publish explicit guidelines on greywater reuse, which means you must assume that state law applies but that county or local water districts may have additional restrictions. The Kern County Water Agency or your local water provider may track or limit greywater harvesting to prevent over-pumping of the aquifer; some southern California districts have begun restricting it.

The practical step: Before installing a greywater system, contact Kern County Public Health (661-868-0201) and ask whether greywater reuse requires a county permit and whether any local restrictions exist. If your property is served by a specific water district (e.g., Delano Irrigation Company, Kern County Water Agency), contact that entity directly and ask the same. If you plan a simple laundry-to-landscape system that qualifies under state law and receives no objection from the county or water provider, you may proceed without a permit. If you plan a more complex system (e.g., shower greywater, treated recycled water), expect to need engineering approval and a permit from the county building or public health department.

Rainwater Harvesting: Legal in California; Kern County Silent

The California Rainwater Capture Act of 2012 explicitly legalized rainwater harvesting. Rooftop collection into a cistern of 360 gallons or less for outdoor non-potable use (landscape irrigation) requires no permit. Larger cisterns or systems intended for potable (drinking) use require a permit and engineering review.

Kern County does not publish explicit rainwater-harvesting rules, but as with greywater, you should verify with Kern County Public Health and your local water provider whether county or district restrictions apply. In an area with severe groundwater depletion, some water districts have begun tracking rainwater captures; this is not yet common in Kern County, but worth confirming.

The practical step: For a simple, unpermitted system (rooftop collection into a 300-gallon tank for landscape use), contact Kern County Public Health and your local water provider and ask whether anything precludes it. If you plan a larger system or potable rainwater use, ask the public health department or your water provider whether a permit is required. In practice, many Kern County residents install small rainwater cisterns without formal approval, but contacting the relevant authority first protects you from future compliance orders.

Utility Disconnection: Not Addressed by Kern County

Kern County guidelines do not specify whether you may disconnect from the electrical grid or natural gas. California state law now explicitly permits off-grid electricity (as of 2020, through AB 2468), but some jurisdictions can still require connection to a sewer or grid if municipal lines run within a certain distance of the property. The final call rests with your local Authority Having Jurisdiction (the county or city building department).

The practical step: Contact your local building department (Kern County Public Works Development Services if unincorporated, or your city's building department if incorporated) and ask directly whether off-grid electricity is permitted and whether gas disconnection is allowed. Ask whether a backup power system, tie-in capability, or other condition is required. Utility companies (Southern California Edison, Pacific Gas & Electric, or a local cooperative) also have disconnection policies; contact your utility and ask whether you may disconnect or whether any fee or safety inspection is required. In most cases, disconnection is now allowed, but confirming in advance prevents surprises during final inspection.

How to Confirm Locally: The Practical Sequence

Start by determining your jurisdiction (incorporated city or unincorporated Kern County). Call Kern County Planning & Natural Resources Division (559-445-2020) to confirm. Then follow this sequence:

1. Zoning and land use: Contact the planning department (county if unincorporated, city if incorporated) and ask whether your parcel's zone permits single-family residential and off-grid systems. Bring your legal description and address.

2. Well and septic: Contact Kern County Public Health (661-868-0201) and Public Works Development Services (559-445-2020) and request applications for a well and septic permit. Ask about minimum lot size, setback distances, and whether a percolation test is required.

3. Greywater and rainwater: Ask the same departments whether county or water-district restrictions apply. Ask to speak with someone in the water or environmental health section.

4. Building permit and dwelling type: Contact the building department and ask whether your proposed dwelling (conventional home, tiny home, RV, etc.) is permitted in your zone and whether it must comply with California Title 24. Ask for a list of required plan documents.

5. Utilities: Contact your local building department and your utility company and confirm whether off-grid electricity and gas disconnection are permitted and whether any conditions apply.

Be prepared to share your legal description, address, parcel size, and a sketch of your proposed systems. Expect responses to take 1-2 weeks. Plan to spend $500-2,000 on permits, testing, and inspections before you begin construction.
