Building permits, zoning and land rules in El Dorado County, California

Yes. Unincorporated El Dorado County requires building permits for new construction, major renovations, electrical and plumbing work, and structural changes, and work cannot begin before approval¹. Required inspections depend on project scope and can include foundation, framing, plumbing, electrical, sheetrock and final inspections; required grading work must be cleared before building inspections begin¹. A covered building, trailer, coach or manufactured housing unit cannot be occupied until the final inspection is approved and a Certificate of Occupancy is issued; required utilities, road work and fire-district approval must also be complete¹¹. Applications dated in 2026 or later use the 2025 California Building Standards Code, while projects initiated earlier remain under the previous code during plan check and inspections¹². The county publishes fee schedules, collects half the building permit fee and the full planning fee at application, and collects the balance and other agency fees at issuance¹³.

El Dorado County's Building Division issues building permits and conducts inspections for regulated work in the unincorporated county^1,14. Reach the Placerville office at 2850 Fairlane Court, Placerville, CA 95667, phone (530) 621-5315, with an alternate line at (530) 621-5377 for inspections¹⁴. Walk-ins run 8 am to noon Monday through Friday except Wednesday, when walk-in hours shift to 9 am to noon, with appointments only from 1 to 4 pm¹⁴. For land in the Lake Tahoe Basin, use the South Lake Tahoe office at 924 B Emerald Bay Road, South Lake Tahoe, CA 96150, phone (530) 573-3330¹⁴. The Planning Division handles zoning, rezoning and subdivision review and can be reached at 530-621-5355^15,16.

Yes. El Dorado County's Title 130 zoning ordinance applies throughout the unincorporated county except listed federal, state, tribal and utility-related exemptions². Incorporated cities use separate municipal zoning, so Title 130 does not govern land inside city limits¹⁷. Residential lot sizes, setbacks and building heights are district-specific; additional agricultural, fire-safe, timber, wetland and riparian setbacks can also apply⁵. Meyers Area Plan parcels in the Tahoe Basin also have TRPA-based land-coverage rules, including special Town Center provisions¹⁸. An accessory dwelling unit or junior accessory dwelling unit is allowed by right in qualifying residential zones but remains subject to site, building, septic and fire rules⁸. The ordinance says dwelling area in mixed-use projects must comply with the building code but gives no numeric minimum there; ask Planning about the rule for the parcel and project^5,15.

Septic systems in El Dorado County go through the county's Environmental Management Department under its Private Sewage Disposal System Ordinance, not a separate state office^3,4. You need a percolation test before a site evaluation report can be completed, then a site approval report, before the county will accept your sewage-disposal-system permit application; the permit is issued only to the owner or an authorized representative⁴. Reach Environmental Management's Placerville office at 2850 Fairlane Court, Building C, phone (530) 621-5300, or the South Lake Tahoe office at 924 B Emerald Bay Rd., phone (530) 573-3450¹⁹. After the permit is approved, a Qualified Professional performs an open-trench inspection on every system, and the county's Environmental Management staff perform the final inspection within two weeks of that inspection³. Statewide, California's Water Boards oversee the policy that local programs like El Dorado's must follow²⁰. Soils are a serious limiting factor here: well under 1% of El Dorado County's soils rate free of severe limits for a conventional drain field in the USDA soil survey, in a county where only about 12% of the land sits at a gentle enough slope to make site work easy, so expect the county to lean on special-design systems in a lot of places²¹.

Not in a residential zone as ordinary camping. El Dorado County's permissive zoning ordinance does not allow camping by right or by conditional use permit in any residential zone⁹. Selected agricultural and recreational zones can allow a campground with a conditional use permit, but campground and RV-park stays are limited to 30 days and Environmental Health must find adequate water or septic capacity⁹. A genuine tiny home is different: the county describes tiny homes under 400 square feet, built on a permanent foundation and meeting Title 24 building codes, as suited to long-term housing, subject to the same zoning, building, fire and septic requirements as any other home⁷. A manufactured home can also be a permanent primary or accessory dwelling by right in a zone that permits a detached single-family home, once it meets the county's foundation, utility, fire and septic standards⁸.

1. Confirm the parcel's zoning district, minimum lot size, setbacks, height limit and allowed use with the Planning Division at 530-621-5355^5,15.
2. Start septic review early: obtain a percolation test, site evaluation and site approval report before Environmental Management, (530) 621-5300, accepts the sewage-disposal permit application^4,19.
3. Apply through Environmental Management for any well construction, destruction, deepening or repair¹⁰. A new driveway connecting to a county-maintained road needs an encroachment permit²².
4. Submit a complete building permit application to the Building Division, (530) 621-5315; the county requires the listed plans and supporting approvals before plan check begins^14,22. An owner-builder must complete the county's owner-builder paperwork and remains responsible for managing and completing the work⁶.
5. Schedule the inspections required by the project's scope, including any grading clearance before building inspections¹.
6. Complete utilities, road work and fire-district approval, then obtain final inspection approval and any required Certificate of Occupancy before moving in¹¹.

Zoning and lot size: ask the Planning Division which district covers the parcel because lot size, setbacks and height limits vary by district, and a proposed subdivision must also satisfy parcel configuration, utilities, fire-safe and road standards^5,15,16. Soils: well under 1% of El Dorado County's soils rate free of severe limits for a conventional septic drain field, and only about 12% of the county's land has a gentle slope, so budget for site-specific evaluation²¹. Agricultural grading is not broadly permit-free: narrow exemptions cover conversion of less than one acre outside the Tahoe Basin and qualifying practices that use approved best management practices without substantially changing natural contours^23,24. Flood status is parcel-specific¹⁶. A well needs a county permit for construction, destruction, deepening or repair¹⁰. El Dorado County's typical effective property tax rate is about 0.7%, with a median annual bill near $4,510²¹.
