San Bernardino County, CA Building Permits, Zoning & Septic

Unincorporated San Bernardino County, California requires a building permit for any new detached building over 120 square feet, issued by the county's Land Use Services Building and Safety Division¹. The county zones every unincorporated parcel under its Development Code, with each property assigned to a zone or land use district². Where there is no sewer, San Bernardino County Environmental Health Services permits the septic system instead of the building office³. California's statewide owner-builder exemption applies here too, but the county permit itself is still required⁴.

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

Yes for most structures. Unincorporated San Bernardino County requires a permit for any new detached residential or non-residential building over 120 square feet, plus tenant improvements, solar, patio covers, additions, pools, carports, fences over 6 feet, retaining walls over 3 feet, re-roofing, grading, demolition and more¹¹¹. A one-story detached shed, tool room or playhouse at 120 square feet or less can be exempt, but only if it has no utilities, meets minimum setbacks and stays under 14 feet tall¹. Structures that already stood before 1946 may carry an exemption under County Ordinance 574, but that exemption disappears the moment the structure is deemed unsafe or is altered, added to, or has a change of occupancy¹¹. California law backs this up statewide: no building may be erected, altered or moved without a permit first obtained from the local building official, and every county building department must enforce the State Building Standards Code¹²¹³. California's owner-builder exemption still applies, but it only changes who can do the work, not whether San Bernardino County requires the permit itself⁴.

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

Building permits for unincorporated San Bernardino County go through Land Use Services' Building and Safety Division, based at the County Government Center, 385 N. Arrowhead Ave., First Floor, San Bernardino, CA 92415-0187¹⁴. Reach Land Use Services at (909) 387-8311; the same government center houses Land Development and Planning/Mining, so one call point covers most of a build¹⁴. Building and Safety enforces the state's Building, Electrical, Plumbing, Mechanical, Energy and disabled-access standards through the permit process: plan review, permit issuance, inspections and a final Certificate of Occupancy¹⁵. Fees changed as of 2026 and are split into Plan Review and Building Permit components, plus any school, traffic or drainage fees that apply to a specific project, so get a project-specific quote from the office before budgeting¹⁶.

Does San Bernardino County have zoning?

Yes, countywide. San Bernardino County regulates zoning for every unincorporated parcel through its Development Code, first readopted in 2007, with each property assigned to a zone or land use district that sets its own use rules and development standards²¹⁷¹⁸. In the county's AG, RC, FW and OS zoning districts across the Valley, Mountain and Desert regions, there is no maximum lot coverage limit, though other Development Code standards still apply¹⁹. Agricultural accessory structures get a break from the planning-permit process, not the building-permit process: structures up to 1,000 square feet need no planning permit in most residential districts, and in the RL district that rises to 10,000 square feet on parcels of 5 acres or less, but a building permit and all setback and height standards still apply⁸. Multi-family dwelling units have their own minimum sizes under the Development Code: 450 square feet for an efficiency, 650 for one bedroom, 850 for two, 1,050 for three, and 1,200 for four or more bedrooms⁹. A single dwelling placed in the county's Alternate Housing Overlay needs at least 725 square feet and 14 feet of width²⁰. California gives counties general authority to zone building height, bulk, lot coverage and setbacks, which is the statewide basis for all of this²¹.

How do septic permits work in San Bernardino County?

Where no sewer connection is available, San Bernardino County Environmental Health Services requires and permits an onsite wastewater treatment system before you can build³⁵. Statewide, septic regulation is split: the State Water Board and regional water boards set the policy, while a local agency like Environmental Health Services carries out permitting under its own Local Agency Management Program²². Soils here make this more than paperwork on many parcels: only about 14.5% of San Bernardino County's soils are rated free of severe limits for a conventional drain field, so budget for a site evaluation and possibly an engineered system¹⁰. If you're eyeing an accessory dwelling unit, know that sewer or septic capacity can determine whether one fits on the lot; the county specifically encourages coordinating with Environmental Health Services early for an ADU, junior ADU or guest house²³.

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

Not as a general matter. San Bernardino County's Development Code makes it unlawful to place, use or occupy any vehicle on a parcel for camping, dwelling or residency unless that use is specifically authorized⁶. The one exception for an ordinary landowner: the property owner may camp recreationally in their own RV or trailer for up to 4 days within any 30-day period, and only in the RC, AG, or RL-5-acre-or-larger zoning districts⁶. Longer use requires a Site Plan Permit and Special Use Permit, such as the county's own exception for RVs used as seasonal labor quarters⁶. Temporary structures used for camping or dwelling face the same rule: no use without a Temporary Use Permit, Special Event Permit or other required approval²⁴. Statewide, California treats RVs as vehicles, not permanent dwellings, and limits their occupancy to mobilehome or special-occupancy parks unless local rules say otherwise, which lines up with San Bernardino County's own ordinance²⁵. A tiny home can be occupied legally only if it qualifies as a HUD-Code manufactured home, a California-code home, factory-built housing, an RV, a park trailer or a camping cabin approved for its site; anything else is a noncomplying structure²⁶. A manufactured home may be sited inside or outside a mobilehome park under the Mobilehome Parks Act, subject to the same local zoning approvals as any other structure, so confirm what a specific parcel's zone district allows before you buy²⁷²⁸.

Building a home in San Bernardino County: the steps, in order

First, confirm the parcel's zone district, minimum lot size and whether a subdivision or road-access issue applies with Land Use Services Planning before you buy²⁸¹⁸. Second, if there is no sewer, get a septic site evaluation from Environmental Health Services, since much of the county's soil needs an engineered system⁵¹⁰. Third, confirm your road is legal access: San Bernardino County only recognizes a road as legal access if it has a dedicated right-of-way to the county and public, or a public-use easement, and road dedication or paving can be required as a permit condition²⁹. Fourth, if the parcel sits in a County Floodplain Overlay or Floodplain Safety Review Area, no structure may be built, altered or converted there without full compliance with the county's floodplain chapter³⁰. Fifth, apply for the building permit through Building and Safety, budgeting separately for Plan Review and Building Permit fee components¹⁴¹⁶. Sixth, if you're an owner-builder, remember the county caps for-sale, licensed-subcontractor structures at 4 a year, and a principal-residence exemption at 2 uses within any three-year period⁷. Seventh, complete inspections in sequence and clear Building and Safety, Planning, Land Development, Public Works Roads and Fire Department sign-off before the county issues your Certificate of Occupancy³¹³².

What to check before you buy land in San Bernardino County

This is a desert and mountain county more than a green one: only 4.1% of the land is wooded, average precipitation is about 6.6 inches a year, and severe drought hits roughly 39% of years³³³⁴³⁵. Terrain is gentler than the numbers might suggest, with 66% of the land at a 15% slope or less, but federal land covers a huge 87% of the county, which limits where private parcels sit and what borders them³⁶³⁷. If you're buying a larger tract with an eye toward splitting it, California's Subdivision Map Act and the county's own Development Code require a Tentative Map first, then a Parcel Map for four or fewer resulting parcels or a Final Map for five or more, plus whatever minimum lot size and improvement conditions apply to that zone³⁸³⁹. Prices reflect the mix of desert and mountain terrain: the typical home value is about $553,855, farmland runs around $47,339 an acre, and a typical home insurance premium is about $1,376 a year⁴⁰⁴¹⁴². The effective property tax rate runs about 0.7%, with a median property tax bill near $3,346 a year⁴³⁴⁴.

Watch-outs

San Bernardino County's Development Code makes vehicle occupancy for camping or dwelling unlawful without authorization; the only exception for an ordinary owner is up to 4 days in any 30-day period, and only in RC, AG or RL-5-acre-or-larger zones, so do not assume year-round RV living is allowed on a given parcel⁶.
No single countywide table gives minimum lot size or setbacks for every zone district; confirm the exact figures for a specific parcel with Land Use Services Planning before you buy²⁸¹⁸.
The county's floodplain rules and road-access (legal-access) requirements can add real cost and delay on a rural parcel; check both with Land Use Services before closing, not after³⁰²⁹.

Water rights & wells in San Bernardino County

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

Adjudicated — rights fixed

Water rights here have been fixed by a court. New supply effectively means acquiring an existing right.

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
