Answers from the rulebook for Dorris

Dorris’s own rules

  • Local zoningPresent (with conditions)

    Land inside Dorris city limits (Siskiyou County, CA). The city administers its own zoning code (Title 18, Zoning). This is not a county rule.

    • The city planning department states it oversees compliance with the zoning code; use and development must comply with the district rules for the parcel.
    • The code text reviewed is the city-posted PDF, a 1999 codification with later ordinances (for example ord. 219, 2014; sections stamped 'revised 5-17'). The planning page links a separate zoning code, which was not opened. Confirm the current adopted text before relying on it.
    • Applies only inside the city limits; unincorporated Siskiyou County land is not covered.
    “oversees compliance with state and local regulations, including but not limited to the general plan, zoning code, subdivision ordinance, and california environmental quality act.”
  • Zoning districtsPublished (with conditions)

    Zoning districts inside Dorris city limits, as listed in Title 18 (Zoning) of the city code. Districts listed include R-A, R-1, R-2, R-3, M-H, C-1, C-2, M, O-S, P-A and PUD.

    • The chapter list is from the city-posted 1999 codification with later amendments; district boundaries are on the zoning map (not opened).
    • Use permitted within each district depends on that district's chapter; this claim only confirms the districts are published.
    “18.09 residential agriculture, r-a 18.10 low density residential, r-1 18.12 medium density residential, r-2 18.14 high density residential, r-3”
  • Minimum lot sizeSpecified

    Single-family lots in the R-1 (Low Density Residential) district inside Dorris city limits

    • The R-1 purpose section states a 6,000 sq ft lot minimum; larger lots are not prohibited by the zone.
    • This is from the purpose statement (section 18.10.010). The site development standards table (section 18.10.040) was referenced but not retrieved, so confirm it.
    • Text is from the city-posted 1999 codification with later amendments; confirm against current code.

    R-1 minimum lot size: >= 6000 sq ft (Larger lots are not prohibited; purpose statement, not the site standards table)

    “the assigned density is consistent with typical residential development with six thousand (6,000) square foot lot minimums. nothing in this zone district prohibits larger lot sizes.”
  • Subdividing landRegulated (with conditions)

    Land divisions inside Dorris city limits

    • Subdivisions require approval by the city council, which checks conformity with law and lot size and shape against city requirements.
    • Subdivision ordinance is linked from the planning page; Title 16 text read is from the 1999 codification with later amendments.
    • Lot line adjustments and other split types were not reviewed.
    “16.04.030 approval by city council. a. the city council shall determine whether the proposed subdivision is in conformity with law, whether the size and shape of the proposed lots are in general conformance to city requirements”
  • Permit processPartial

Unanswered questions are usually a sign that Dorris publishes no rule on the point, not that none exists. Siskiyou County’s page lists the county offices to call.
