Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Mendocino County
Tentative parcel maps: Mendocino County Code Title 17 (Division of Land Regulations), Chapter 17, Article V — Minor Subdivisions; tentative map review and approval procedure at Section 17-48.5 ("Recommendation of Subdivision Committee") following the tentative map submittal requirements at Section 17-47(A). Major subdivisions (final maps) are governed by Article IV of the same chapter.
Submittal checklist →Checklist verified live is the county's 'Minor Subdivision Application' packet (PDF, published/updated Aug 2025) issued by Dept. of Planning & Building Services — it doubles as both the application form and the submittal checklist (tentative map contents list, filing requirements). Code section confirmed by directly reading the rendered Municode article text (library.municode.com is a JS single-page app that blocks generic fetchers with a 403; content was retrieved successfully via a rendering proxy, and the returned section text — 'The Subdivision Committee shall examine each proposed tentative map for compliance...' at node S17-48.5 — matches Section 17-48.5 as the tentative-map review section).
The county's own Minor Subdivision Application (the authoritative current form) states verbatim: 'Check with a planner prior to submitting an application for the current fee. All fees are collected by the Department of Planning and Building Services.' A companion form referenced in the packet is titled 'Acknowledgement of Deposit/Hourly Fee,' confirming the fee is billed on a deposit/actual-cost basis rather than a published flat amount. Could not find a second source publishing an actual current dollar figure (the Dec-2024 Master Fee Schedule / Exhibit X spreadsheet on Legistar could not be rendered as text) — this is single-sourced to the application packet itself, which is authoritative for the process but does not give a dollar figure to corroborate.
Verified live on the County Recorder's official Fee Schedule page, which lists 'Filing of Maps -- 1st page - GC 27372: $9.00' and 'Each additional page: $2.00' as a separate line item from the standard document recording fee. Only one live source found for this specific map-filing fee; general searches independently corroborated the standard $13/$3 document fee (GC 27361) via multiple secondary sites, but not a second source specifically for the GC 27372 map fee, so treat the map-fee figure as single-sourced to the Recorder's own published schedule.
City of Ukiah
Tentative parcel maps: Ukiah City Code, Division 9 (Planning and Development), Chapter 1 (Subdivision), Article 18 (Minor Subdivision) — governs tentative parcel maps for minor land divisions (4 or fewer parcels).
Submittal checklist →Checklist verified live: City of Ukiah 'Minor Subdivisions' handout listing full Tentative Map submittal requirements, staff contacts, and a direct citation to 'Ukiah City Code Division 9 (Planning and Development), Chapter 1 (Subdivision), Article 18 (Minor Subdivision).' Handout last revised 9/29/2014 per its footer, but staff contact names/numbers on it match the current fee schedule's phone/fax, so it appears still in active use.
From the City's '2024 Fees for Planning Permits and Related Services,' adopted by City Council effective 2/21/24, table entry 'Subdivision — Minor: $1,000' (flat; not deposit/cost-recovery like the Major Subdivision line). This is the only fee-schedule source found; no second corroborating document was located restating this exact figure, so treat as single-sourced to the official adopted fee schedule PDF.
