Bathroom & Shower Remodeling Across the Sierra Foothills
We work a contiguous band of foothill communities along I-80 and Highway 49 — from Loomis at about 350 feet up to Alta near 3,800 — across Placer County and western Nevada County, with Auburn at the centre.

The territory, in six verifiable lines
- Two counties: Placer County and western Nevada County — every community listed below was checked against the Census county boundary, not its mailing address.
- About 3,400 vertical feet from Loomis (approx. 360 ft) to Alta (approx. 3,800 ft), on four connected corridors along I-80 and Highway 49.
- Six permit offices, not two: Auburn, Loomis, Colfax, Grass Valley, Placer County and Nevada County. Nevada City contracts its building services to the county.
- Two addresses that mislead: Lake of the Pines is Auburn 95602 mail but a Nevada County permit; Alta Sierra is Grass Valley 95949 mail but also a Nevada County permit.
- Same code everywhere: a shower of at least 1,024 sq in that contains a 30-inch circle (CPC §408.6), a valve capped at 120°F (§408.3), safety glazing (CRC §R308.4.5).
- Water is soft on the PCWA systems serving Auburn, North Auburn, Newcastle and Loomis — the film on shower glass is soap scum, not scale.
Sources: county membership and community points from US Census TIGERweb; elevations from the USGS 3DEP elevation point query service at those points (one point per community, rounded to the nearest 10 ft); permit authority from each office's own site (verified 2026-09-19); 2022 California Plumbing Code §408.3 and §408.6; California Residential Code §R308.4.5; PCWA water quality reporting.
One contiguous territory, not a list of cities.
Our Auburn location works a connected stretch of the Sierra Nevada foothills rather than a scattering of unrelated markets. Everything we serve sits on one of four corridors: the low western foothills along I-80 below Auburn, the climb east from Auburn toward Colfax and Alta, the Highway 49 run north into Nevada County, and the western Nevada County branch toward Penn Valley.
That matters more than it sounds. A bathroom in Loomis at roughly 360 feet and a bathroom in Alta near 3,800 feet are not the same job — about 3,400 vertical feet separate them, and that changes winter access, delivery scheduling and, at the top end, what you should think about for supply lines running through an unheated exterior wall. Housing varies just as widely, from the oldest stock in the Gold Rush towns to gated lake communities built out as planned developments.
What does not vary is who we are: a bathroom- and shower-focused remodeler working out of Auburn, close enough to every community on this page to come back if something needs attention after the job is finished. The Sacramento side of the region is covered by our Rocklin office instead.
Where we work, in the order you’d drive it.
Elevations are approximate — one USGS reading near the middle of each community — and they are listed because in the foothills they are a practical detail, not trivia. Linked communities have a dedicated page.
Western Foothills
Placer CountyThe low end of the territory, west of Auburn along I-80. Elevations run from roughly 350 to 1,500 feet — close enough to the valley that winter access is rarely a factor. Loomis is an incorporated town with its own building division; the rest is unincorporated and permits through Placer County.
- Bathroom remodeling in Loomis≈ 360 ft
- Bathroom remodeling in Penryn≈ 630 ft
- Ophir≈ 690 ft
- Bathroom remodeling in Newcastle≈ 800 ft
- Auburn≈ 1,210 ft
- Bathroom remodeling in North Auburn≈ 1,480 ft
I-80 Foothill Corridor
Placer CountyClimbing east from Auburn, this is where elevation starts to matter. Colfax is around 2,400 feet and Alta around 3,800 — high enough that a winter storm can move a delivery day, and high enough to think about freeze exposure on supply lines in exterior walls.
- Auburn≈ 1,210 ft
- Bathroom remodeling in Meadow Vista≈ 1,710 ft
- Applegate≈ 2,000 ft
- Weimar≈ 2,250 ft
- Bathroom remodeling in Colfax≈ 2,380 ft
- Alta≈ 3,800 ft
Highway 49 / Nevada County
Nevada CountyNorth from Auburn on Highway 49 and across the county line. Grass Valley issues its own permits inside the city limits; everything else on this corridor — including Nevada City, which contracts its building services to the county — is a Nevada County permit.
- Bathroom remodeling in North Auburn≈ 1,480 ft
- Bathroom remodeling in Lake of the Pines≈ 1,550 ft
- Bathroom remodeling in Alta Sierra≈ 2,080 ft
- Bathroom remodeling in Grass Valley≈ 2,450 ft
- Bathroom remodeling in Nevada City≈ 2,390 ft
Western Nevada County
Nevada CountyThe western side of the county, out toward Penn Valley. Two of the three communities here are gated lake communities with their own associations, which makes site logistics — gate access, delivery windows, debris staging — part of the plan rather than an afterthought.
- Bathroom remodeling in Lake of the Pines≈ 1,550 ft
- Penn Valley≈ 1,450 ft
- Bathroom remodeling in Lake Wildwood≈ 1,450 ft
The communities listed without a link — Ophir, Applegate, Weimar, Alta, Penn Valley — are places we cover that are small enough not to need a page of their own. Ophir, Applegate and Weimar are unincorporated Placer County; Penn Valley is unincorporated Nevada County; Alta is a small Placer County community at the top of the I-80 corridor. If your address is in one of them, call us and we will confirm it straight away.
Who issues your building permit
Six offices operate across this one territory, and the boundary that matters is the city limit — not the postal city on your envelope. Getting it wrong is an avoidable delay.
| If you live in | Your permit comes from |
|---|---|
| Auburn, inside city limits | City of Auburn Building Division (official page) |
| North Auburn, Newcastle, Penryn, Ophir, Meadow Vista, Applegate, Weimar, Alta, Gold Hill | Placer County |
| Loomis, inside the town limits | Town of Loomis (official page) |
| Colfax, inside city limits | City of Colfax (official page) |
| Grass Valley, inside city limits | City of Grass Valley (official page) |
| Alta Sierra, Lake of the Pines, Lake Wildwood, Penn Valley, Wolf — and Nevada City, which contracts building services to the county | Nevada County (official page) |
Three cases are worth calling out, because homeowners get them wrong often enough that we now check first:
Lake of the Pineshas an Auburn mailing address — ZIP 95602 — but sits in Nevada County. The mail says Auburn; the permit does not.
Alta Sierra shares ZIP 95949with Grass Valley, so addresses read “Grass Valley, CA 95949.” But Alta Sierra is unincorporated, so the permit comes from Nevada County, not the City of Grass Valley.
Nevada City has its own planning department, but it contracts building department services to the county: you apply with the city, then the city-approved plans go to the Nevada County Building Department, which issues the permit.
We pull the permit as part of the job, so this is our problem to get right rather than yours. It is still worth knowing which authority you are dealing with before anyone quotes you a timeline — and what the fee is built from, which our cost guide sets out office by office with links to the adopted fee schedules. Each authority above also has a detailed guide: Placer County, Nevada County, the City of Auburn and the City of Grass Valley.
What’s different about a foothill bathroom
Only the things that genuinely change the work. Not everything on this list applies to every address.
Elevation, where it actually matters
Our territory spans about 3,400 vertical feet. At the top of the I-80 corridor — Colfax around 2,400 feet, Alta near 3,800 — winter weather can affect a delivery day, and freeze exposure on supply lines in exterior walls is a real design consideration. At Loomis, around 360 feet, none of that applies. We plan for altitude where it exists and ignore it where it does not.
Wells and septic systems
Common on rural foothill properties, and worth confirming before design rather than during demolition. Well water can affect finish choices — iron staining of light grout is the issue we ask about most — and it is a per-property question, not a per-town one, so we check rather than assume.
Treated water here is soft, not hard
On the PCWA systems that serve Auburn, North Auburn, Newcastle and Loomis, water under 60 mg/L is classed as soft and the Foothill/Sunset system averages around 21.75 mg/L. That matters for what you buy: the film on shower glass here is soap scum, and it comes off with cleaning rather than needing a softener to prevent scale.
Older housing stock
The Gold Rush towns carry genuinely old buildings, and bathrooms in homes of that vintage were usually retrofitted into rooms never designed for them. Expect undersized framing bays, drain lines in awkward places, and wall thicknesses that decide where a niche can go. Pre-1994 homes also carry a code obligation: under Civil Code §1101.4, noncompliant water fixtures elsewhere in the house must be replaced before a permit for an alteration can be finaled.
Gated lake communities
Lake Wildwood and Lake of the Pines are both gated and both run by an association. Crew access, delivery windows and debris staging have to be arranged in advance, and association rules sit on top of — not instead of — the county building permit. It is a scheduling difference rather than a difficulty, as long as somebody plans for it.
