Buying Land in San Bernardino County, California

One county, several genuinely different land markets

San Bernardino County's southwestern edge -- Rancho Cucamonga, Ontario, Fontana, and the city of San Bernardino itself -- is dense Inland Empire suburb, built on conventional zoning and largely built out. Moving north and up in elevation, the San Bernardino Mountains hold long-established resort and cabin communities at Big Bear Lake and Lake Arrowhead, bordered by San Bernardino National Forest. North and east of the mountains, the county opens into vast Mojave Desert territory -- Victorville, Barstow, Twentynine Palms, and enormous stretches of BLM and private desert land running to the Nevada border.

The Mojave Desert and utility-scale solar development

San Bernardino County's desert has become one of the country's most significant sites for utility-scale solar power, most visibly the Ivanpah Solar Electric Generating System near the Nevada border, completed in 2014 as one of the world's largest concentrating solar power facilities at the time. That development didn't happen in a regulatory vacuum: the Desert Renewable Energy Conservation Plan (DRECP), a joint federal-state land-use plan finalized in 2016 covering millions of acres of California desert across several counties including San Bernardino, designates specific Development Focus Areas intended to steer utility-scale solar and wind toward lower-conflict land while protecting other desert areas for conservation.

For a landowner or buyer considering a lease to a solar or wind developer, or evaluating whether nearby large-scale renewable development affects a parcel's value or character, the DRECP framework is the right starting point -- see the dedicated wind-solar-leasing page below for how it actually structures desert land use in this county.

Mountain communities: a different feasibility picture entirely

Big Bear Lake and Lake Arrowhead developed as mountain resort communities beginning in the early 20th century and remain popular for cabins, vacation homes, and short-term rentals today. Both sit within San Bernardino National Forest's surrounding footprint and in State Responsibility Area wildland-fire territory, meaning CAL FIRE holds primary wildland-fire authority and Fire Hazard Severity Zone-based building and defensible-space requirements can apply. Elevation-appropriate snow-load construction standards are also a real factor at these elevations, distinct from the desert or valley portions of the county.

Desert land near federal boundaries

Away from the solar-development corridor, much of the county's remaining desert land is either BLM-managed public land or private parcels bordering it, including areas near Mojave National Preserve (established by the California Desert Protection Act of 1994) and Joshua Tree National Park. For remote desert parcels, confirming legal and physical road access, any grazing allotment or mineral-rights history, and groundwater availability are more central due-diligence steps than in more developed parts of the county.
