Electrician in Rimforest, CA: Serving the Oldest Corner of the San Bernardino Mountains

Quick answer: Rimforest sits at 5,642 feet along State Route 18, and it's genuinely one of the oldest developed communities in the San Bernardino Mountains — home to the Daley Toll Road Monument, marking the first wagon road ever built into these mountains back in 1870. With a population of only around 400, it's also one of the smallest, tightest-knit communities on the mountain, with a housing stock old enough that knob-and-tube wiring, not just aluminum wiring, is a genuine concern for some properties.



Why Is Rimforest the Mountain's Oldest Access Point?

Long before the Rim of the World Highway was dedicated in 1915, the Daley Toll Road — built in 1870 by Edward Daley and his sons — was the first road into the San Bernardino Mountains capable of handling wagons, running from the city of San Bernardino up toward what's now Lake Arrowhead. It served loggers, cattlemen, and sheepherders for two decades before becoming a county road in 1890. The monument marking it, a California Historical Landmark, still sits just east of Rimforest today. That history matters for a practical reason: Rimforest was one of the first parts of this stretch of mountain to see real development, with subdivision of the original Redwood Springs Ranch beginning in 1921.

What Does Rimforest's Early Development Mean for Its Electrical Systems Today?

Because tracts here were platted and built out starting in the 1920s through the 1940s, Rimforest has a meaningfully older baseline housing stock than communities that developed primarily in the 1960s-70s boom seen elsewhere on the mountain. That earlier construction era means some Rimforest cabins may still have original or partially original electrical systems dating back much further than the aluminum wiring era we typically flag in newer 1960s-70s mountain construction.

Knob-and-Tube Wiring: The Issue Even Older Than Aluminum Wiring

Knob-and-tube wiring was the standard residential wiring method roughly through the 1940s, using ceramic knobs and tubes to route individual conductors through wall cavities and framing, with no ground wire and cloth or rubber insulation that degrades significantly with age. It's not automatically dangerous if it's been well-maintained and never buried under modern insulation — but it also can't safely support the load a modern household demands, it lacks grounding for sensitive electronics, and many insurers either won't cover a home with active knob-and-tube wiring or require an inspection and partial upgrade first. If your Rimforest cabin is old enough to potentially have original wiring, this is worth having evaluated directly rather than assumed either way.

A Small, Tight-Knit Community: What That Means for Local Electrical Service

With a population of roughly 400, Rimforest doesn't have the commercial infrastructure of Blue Jay or the tourist draw of Skyforest — it's a genuinely quiet residential community where word of mouth matters and an unfamiliar contractor stands out. Working this corridor regularly means understanding both the area's older housing stock and its specific access points along Highway 18, rather than treating it as an afterthought stop between larger communities.

What Are the Most Common Electrical Problems in Rimforest's Oldest Cabins?

Beyond potential knob-and-tube wiring in the oldest structures, the same broader mountain patterns apply — undersized panels, aluminum branch wiring in mid-century additions, and outdoor circuits worn down by decades of freeze-thaw cycling. If you've recently purchased an older Rimforest property, our guide to choosing a mountain electrician covers what a proper initial assessment should include, and our panel upgrade guide covers what a modernization project typically involves.

How Does San Bernardino County Permitting Work for Rimforest?

Electrical work here falls under the same San Bernardino County Land Use Services jurisdiction as the rest of the mountain. For older homes with non-standard historic construction, permit review can take slightly longer if existing wiring documentation is limited, which is common for properties this old.

How Much Does an Electrician in Rimforest Charge?

• Service call / diagnostic: $125–$195

FAQ

Does Rimforest have older homes than the rest of the Lake Arrowhead area?
Many do. Rimforest's original tracts were subdivided starting in 1921, decades before the 1960s-70s development boom seen in much of the broader area, so some cabins here have a genuinely older baseline construction era.

What is knob-and-tube wiring, and is it dangerous?
It's an early wiring method common through the 1940s, using ceramic knobs and tubes with no ground wire. It's not automatically dangerous if well-maintained, but it can't safely support modern electrical loads and many insurers require an upgrade before providing coverage.

Why is Rimforest historically significant?
It's home to the Daley Toll Road Monument, marking the first wagon road built into the San Bernardino Mountains in 1870, decades before the modern Rim of the World Highway existed.

Do I need a panel upgrade if my Rimforest cabin has knob-and-tube wiring?
Often a full or partial rewire is recommended alongside a panel upgrade, since knob-and-tube circuits generally can't be safely integrated with modern high-capacity electrical demand. An assessment determines the right scope for your specific property.

Is it hard to get an electrician out to a small community like Rimforest?
It shouldn't be, but confirm before hiring, since Rimforest's small size means some contractors treat it as an afterthought. We work this section of Highway 18 regularly.
