Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Marin County
Tentative parcel maps: Title 22 (Development Code), Article VI (Subdivisions), Chapter 22.84 (Tentative Maps) — e.g. §22.84.040 (Tentative Map Public Hearing)
Submittal checklist →Article VI of Title 22 Development Code is Marin County's Subdivision Ordinance (adopted June 24, 2003, amended since). Confirmed chapter/section structure via Municode nodeId string (TEMA = Tentative Maps, PUHE = Public Hearing) — the Municode page itself is JS-rendered and could not be fully text-scraped, so the section heading text is inferred from the node path, not directly quoted. Checklist is published by Public Works (DPW), not Planning — Marin's Land Development/Surveying counter reviews tentative and final maps jointly with Planning. DPW checklist page last updated per search results June 20, 2024.
This is the fee schedule PDF currently linked (July 2026) from the live Marin CDA Planning Division Fees page (https://www.marincounty.gov/departments/cda/planning/planning-permits/planning-division-fees). marincounty.gov and assets.marincounty.gov are Cloudflare-blocked to automated fetches; page and PDF were loaded in a real Chrome session and the PDF text extracted in-browser (pdf.js) — items 32-36, 'Property Modification: Tentative Map – Major/Minor/Amendment/Extension to Vest/Waiver'. Amounts match the FY 2024-25 adopted column of the Board's fee exhibit ('EXHIBIT A – MARIN CDA PLANNING DIVISION FEE SCHEDULE', FY 2024-25 Fee Amount column, https://marin.granicus.com/MetaViewer.php?view_id=33&clip_id=12349&meta_id=1343182). No FY 2025-26 or FY 2026-27 planning fee schedule has been published as of July 2026 — the November 2024 (FY 24-25) schedule is the county's current published schedule. Replaces the stale FY 23-24 figures (Major $23,910 etc., asOfDate 2023-06).
Assessor-Recorder-County Clerk fee schedule page, marked 'Page updated December 26, 2025.' Single-sourced (no second independent corroborating page found), but it is the county's own live official fee page, explicitly citing Government Code §27372 for the map-filing fee tier.
City of San Rafael
Tentative parcel maps: San Rafael Municipal Code (SRMC) Title 15 (Subdivisions) — Chapter 15.02 (Tentative Maps, e.g. §15.02.040 written statement, §15.02.130 phased final maps), Chapter 15.01 (General Provisions/Exceptions, §15.01.120), Chapter 15.04 (Vesting Tentative Maps), Chapter 15.07 (Hillside Subdivisions)
Submittal checklist →Section numbers quoted directly from the city's own 'Subdivision Submittal Requirements' page text, which cites SRMC 15.02.040, 15.01.120, 15.02.130, 15.04, and 15.07 by number. Minor subdivisions (4 or fewer lots) require a Parcel Map; major subdivisions (5+ lots) require a Tentative/Final Map, both filed with the Department of Community Development.
Pulled directly from the City's current Master Fee Schedule, Planning Services section 5, hosted June 2026 — this is the live, current fee document (linked from https://www.cityofsanrafael.org/master-fee-schedule/). Only one source found (the master fee schedule itself); no second corroborating staff report was located.
San Rafael has no separate recorder; final/parcel maps for city subdivisions are recorded with the Marin County Recorder like all other Marin jurisdictions.
