Do you need a building permit in Alpine County, California?

Yes. Alpine County generally requires permits for improvements, replacements and repairs, and requires a separate permit before a building or structure is erected, enlarged, altered, repaired, moved, improved, removed, converted or demolished.51 The county identifies new attached or detached structures larger than 120 square feet, carports, garages, barns and grading of at least 50 cubic yards among work requiring permits and inspections; setbacks still apply when work is permit-exempt.1

Alpine County has adopted and enforces the California Building Standards Code in Title 24, including applicable local amendments for buildings in flood hazard areas.14 Building Safety reviews plans before permit issuance and periodically inspects permitted work.3 Property owners may receive permits as owner-builders, but they accept responsibility for the work and worker safety and must follow the county's residence, labor and resale conditions.1015 Owner-builder status does not eliminate building-permit or inspection requirements.53

Who issues Alpine County building permits, and how do you apply?

The Alpine County Building Safety Division accepts building applications through the county's online portal, reviews plans and periodically inspects permitted work.16173 The office is at 50 Diamond Valley Rd in Markleeville and can be reached at 530-694-2140.16

The applicant must provide the information relevant to the proposed project and route plans for required agency approvals before permit issuance.17 Alpine County publishes a plan-review deposit estimated at $1.00 per square foot up to $2,500.00, subject to the Building Official's determination.18 If part of the project can be occupied safely before all permitted work is complete, the building official may issue a temporary certificate of occupancy for up to 90 days; a written extension request must show circumstances beyond the applicant's control.19 Projects that need special inspections must file a final report before a Certificate of Use and Occupancy is issued, and enclosing space under an elevated building in a flood hazard area requires a recorded nonconversion agreement first.20

Does Alpine County have zoning?

Alpine County has countywide zoning under Title 18, with allowed uses, setbacks, parking requirements and height limits varying by district.2 The AG Agriculture Zone generally requires 20 acres, the NC Neighborhood Commercial Zone requires 10,000 square feet and the C Commercial Zone requires 5,000 square feet, although conditional uses can change those minimums.212223 In RN and RE zones, the county sets minimum parcel size site by site based on services, environmental conditions and the General Plan; a zoning suffix can state the result.2425 Where public water or sewer is unavailable, lot size must also comply with the county's onsite-wastewater program.26

The MHD Markleeville Historic District uses the underlying zone's lot-area rule unless its design guidelines are more restrictive.27 A CR Commercial Recreation combined zone generally inherits area and width standards from its paired zone, with the more restrictive rule controlling when the standards differ.28 A single-family unit must contain at least 600 square feet of floor area and measure at least 20 feet in its least dimension.11 In the AG Zone, standard front, side and rear yards are each 30 feet unless changed for a conditional use.29 The Planning Division handles zoning maps and code enforcement.30

How do septic permits work in Alpine County?

Alpine County Health Department Environmental Health permits residential septic systems and inspects their installation.4 For construction needing a new or replacement onsite wastewater treatment system, submit a permit application and scaled plot plan to Environmental Health; that approval must come before Building Safety can issue its permit.7

Site feasibility deserves early attention: only 0.4% of mapped county soils are rated without severe limitations for a conventional septic drain field.31 That soil statistic does not decide an individual parcel, but it makes a parcel-specific evaluation especially important. Alternative or supplemental systems require annual inspection, and service inspections trigger written reporting requirements.32 Cesspools, surface effluent discharge and systems dedicated to substantial RV holding-tank waste are not authorized.33

Can you live in an RV or tiny home in Alpine County?

Alpine County allows living, sleeping or camping in an RV on a private site owned by the occupant, or used with the owner's written consent, for no more than 16 days per calendar year unless the Planning Commission approves an occupancy-permit extension.34 An extension may require advance notice, sanitary-waste receipts, Environmental Health approval and a one-RV limit.35

A tiny home must qualify and be approved under an authorized housing category, but we could not confirm a more specific Alpine County tiny-home occupancy rule; ask Planning and Building Safety before relying on one as a dwelling.36 A single mobile or manufactured home may be treated as a single-family residence in the AG, AP, RE and RN zones after approval of a certificate of compatibility.12 Alpine County permits ADUs in listed districts, but an ADU cannot be a short-term rental and must be rented for more than 30 days.3738

Building a home in Alpine County: what are the steps?

  1. Ask Planning to confirm the parcel's zoning, allowed residential use, setbacks and height standard.3940
  2. Confirm legal access; driveway work in a county road right-of-way requires an encroachment permit from Engineering.41
  3. Resolve water and wastewater early. A new or replacement septic system needs Environmental Health approval before a building permit, and well construction requires a county permit.713
  4. Submit the building application and project information through the online portal, then obtain required agency sign-offs.17
  5. Complete plan review, pay the applicable fees and call Building Safety for inspections as work reaches each required phase.183
  6. Do not occupy unfinished permitted space without Building Official approval; a temporary certificate is limited to 90 days unless a written extension is granted.19

What should you check before buying land in Alpine County?

Start with buildability, not acreage alone. Only 8.2% of Alpine County land has a slope of 15% or less, and 0.4% of mapped soils avoid a severe conventional-drain-field limitation.4231 Ask Planning about zoning, Environmental Health about septic and well feasibility, and Engineering about driveway access.304344

If land is being split, a tentative parcel map covers a division into four or fewer parcels, while a tentative subdivision map is required for five or more; a final or parcel map cannot go to the recorder until required improvements are completed or secured by agreement.4546 A residential short-term rental requires a county license, and the East Slope overlay caps licenses outside commercial zones at 35.4748 Projects in the Bear Valley, Kirkwood and Markleeville service areas also need the applicable provider's water or sewer approval before a building permit.49

Watch-outs

  • Permit-exempt work must still maintain Alpine County's applicable building setbacks.1
  • Private-site RV occupancy or camping is limited to 16 days per calendar year unless the Planning Commission approves an occupancy-permit extension.89
  • Environmental Health must approve a required new or replacement septic system before Building Safety can issue the building permit.7
  • A driveway connection involving a county road right-of-way requires an Alpine County encroachment permit.41
