Do you need a building permit in San Benito County, California?

San Benito County, California requires a building permit before you build, add onto, alter, move or demolish most structures in the unincorporated county1. The Resource Management Agency's Building Division reviews plans and issues permits under the California Building Code, the International Code Council's model codes and the National Electric Code4. California's own permit statute puts it plainly: no building or structure may be erected, altered, repaired, moved or demolished without a separate permit from the local building official18. San Benito County's own code adopts the 2022 California building, residential and fire codes by reference with local amendments, and we could not confirm a county ordinance adopting the newer 2025 edition, so ask the Building Division which edition applies to your application19. If you remodel, repair or enlarge more than 50% of an existing structure, the county treats the whole structure as new and requires it to meet current code, with added fees20. Inside Hollister, the city runs its own zoning, and the county's rules here cover only unincorporated land3. Owner-builders may pull the permit themselves by signing an owner-builder declaration and becoming the responsible party of record1213.

Who is the San Benito County building department and how do you reach them?

San Benito County's Resource Management Agency (RMA) issues building permits and reviews plans through its Building and Code Enforcement Division4. RMA brings together planning, building, code compliance and public works at 2301 Technology Parkway in Hollister4. The same office and phone line handle the Planning Division, which reviews zoning applications, variances and subdivision maps for the unincorporated county21. The county's Building Permit Application and related forms are posted online, but the page does not lay out the full review, payment and inspection sequence, so ask the Building Division what to expect after you apply22.

Does San Benito County have zoning?

San Benito County zones the entire unincorporated county: every parcel has a base zone, and specific-plan or combining zones can modify the rules28. Districts include Agricultural Rangeland (AR), Agricultural Productive (AP), Rural (R), Rural Transition (RT), Rural Residential (RR), single-family Residential (R-1) and Multifamily Residential (RM)9. Minimum lot sizes are large in the rural zones: 40 acres in AR, 5 acres in AP and R, and 2.5 acres in RT; RR runs 0.5 to 1 acre depending on public sewer and water, and R-1 needs 5,000 square feet, 1 acre or 2.5 acres depending on services, with septic on a well pushing it to 2.5 acres7. Height is capped at 35 feet in AR, AP, R, RT, RR and RM, and 30 feet in R-123. Front setbacks are 30 feet in AR, 25 feet in AP, R, RT and RR, and 20 feet in R-1 and RM; interior side setbacks are 32 feet and rear setbacks 35 feet in the four rural districts24. Residential lot coverage tops out at 40% in RR and R-1 and 60% in RM25. Inside Hollister, the city adopts its own zoning ordinance, which it is currently overhauling, so a mailing address alone will not tell you which rulebook applies326.

How do septic permits work in San Benito County?

Septic systems — formally onsite wastewater treatment systems, or OWTS — fall under San Benito County Environmental Health, which permits new systems, repairs, engineered systems, commercial systems, alternative or innovative systems, and system abandonment1011. Fees are non-refundable and vary by system type: $855 for a new system or major repair, $445 for a minor repair, $980 for an engineered individual system, $1,100 for a commercial system, $2,148 for an alternative or innovative system, and $151 to abandon an old system11. You will need an accurate plot plan showing the system and its 100% expansion area, and you must notify Environmental Health with your installer's name and license number before work begins11. California's statewide OWTS policy sets minimum standards through the State Water Board and regional water boards, but San Benito County Environmental Health administers the permit locally, and its local rules must stay consistent with that statewide policy27. We could not confirm from an official county source whether a separate final inspection is required before a system can be covered, so ask Environmental Health directly when you apply5.

Can you live in an RV or tiny home on your land in San Benito County?

San Benito County allows a tiny home on wheels as a primary residence or accessory dwelling unit on unincorporated land outside Hollister city limits, as long as the zoning district allows a residential dwelling or ADU and the unit meets the county's detailed standards14. Those standards are specific: the tiny home must run between 150 and 400 gross square feet, sit on a paved parking pad with its wheels and undercarriage hidden behind a solid apron, connect to approved water and sewer utilities, and meet either ANSI 119.5 or NFPA 119214. A tiny home on wheels can be towed at up to 14 feet tall, though a home placed permanently on a lot may exceed that height if it still meets local roadway limits14. An ordinary RV is a different case: California generally limits RV occupancy to mobile home parks or special occupancy parks unless a local ordinance says otherwise28. San Benito County's own ordinance allows low-impact camping, including dry RV camping, only in the AR, AP, R, RR and RT zones, and it is temporary only: the sleeping accommodation may not be used for permanent human occupancy, and no camper may stay more than 14 consecutive nights15. The county allows permanent RV occupancy only in a qualifying rural farmworker housing project of at least five farmworkers, with a county license and permits16. We found no county rule letting an owner live full time in a single RV on raw land, so confirm with the Resource Management Agency's Planning Division before you try21. A detached accessory dwelling unit, up to 1,500 square feet, has no minimum size beyond the building code's efficiency-unit standard and needs Environmental Health clearance for water and wastewater29.

How do you build a home in San Benito County, step by step?

  1. Confirm your parcel's zoning district and minimum lot size with the Resource Management Agency's Planning Division before you buy — San Benito County's rural districts require anywhere from 2.5 to 40 acres depending on the zone217.
  2. If you are dividing or combining parcels, get your map reviewed under the county's Subdivision Map Act ordinance before you record anything3031.
  3. Apply for your septic permit with San Benito County Environmental Health and budget for the system-specific fee, from $151 for an abandonment to $2,148 for an alternative or innovative system511.
  4. If you need a new or modified well, apply through the San Benito County Water District, which coordinates with Environmental Health on groundwater-protection standards3217.
  5. Submit your building permit application to the Resource Management Agency's Building Division along with your site plan, and expect published engineering and planning fees on top of the permit itself, such as $255 for a C-District review of an existing building or $523 for new construction433.
  6. If you are putting an agricultural building on a parcel larger than 5 acres, ask the Planning Department about the impact-fee exemption when you file the building permit application; the exemption does not waive the permit itself, and projects that miss it can ask the Board of Supervisors for a reduction, deferral or waiver34.

What should you check before buying land in San Benito County?

San Benito County's nearest metro-scale city is about 36 miles from the county's center, so factor real drive time into daily life if you are not near Hollister35. Land here is not cheap relative to its rural feel: farmland recently priced around $5,362 an acre, and the typical home value is about $771,210, among the higher figures in this county-guide series3637. Water is the county's biggest swing factor — it gets only about 17 inches of rain a year and has been in severe drought roughly 37% of years on record, and any new or modified well needs a San Benito County Water District permit383932. Septic siting deserves real scrutiny here: only about 6% of the county's soil is rated free of severe limits for a conventional drain field, so plan on an engineered or alternative system being the norm rather than the exception, and budget accordingly40. Only about 20% of the county's land sits at 15% slope or less, so a lot of San Benito County is hillier than it looks on a map, and grading and access costs can add up fast41. Property taxes run a typical effective rate around 0.8%, with a median bill near $6,078 a year, reflecting the county's high home values4243.

Watch-outs

  • San Benito County's zoning ordinance applies only outside Hollister city limits; the city of Hollister runs its own separate zoning ordinance that it is currently overhauling, so confirm which jurisdiction actually covers your parcel26.
  • Driveways onto a State highway need a Caltrans encroachment permit, and we could not confirm San Benito County's own driveway or encroachment permit process, so ask the Resource Management Agency before you plan a new access point444.
  • Only about 6% of San Benito County's soil is rated free of severe limits for a conventional septic drain field, so budget for a site evaluation and likely an engineered or alternative system before you commit to a building site40.
  • We could not confirm a minimum dwelling size for a primary home in unincorporated San Benito County; only detached accessory dwelling units are stated to have no minimum beyond the efficiency-unit standard, so ask the Resource Management Agency's Planning Division before you design a small home2921.
  • The county's building codes cite the 2022 California edition, and we could not confirm a county ordinance adopting the 2025 edition, so ask the Building Division which applies to your application19.
  • Residential developments subject to the county's inclusionary-housing in-lieu fees must pay them in full before a certificate of occupancy and final inspection45.

Water rights & wells in San Benito County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from California’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellPermit required — restricted

California requires no STATE permit for a domestic well — wells are permitted by the county — but under SGMA a Groundwater Sustainability Agency can meter or restrict new wells in medium/high-priority and critically overdrafted basins, and Executive Order N-7-22 requires counties in those basins to get GSA verification that a new well is consistent with the Groundwater Sustainability Plan before permitting.

Limit: 2 acre-feet/year de minimis under SGMA (Water Code §10721(e)) — largely exempt from GSA metering/fees
