Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Alameda County
Tentative parcel maps: Alameda County Code of Ordinances, Title 16 (Subdivisions), Chapter 16.08 (Tentative Maps); Final/Parcel Maps in Chapter 16.12 (Final Maps and Parcel Maps).
Submittal checklist →Checklist source is the CDA Planning Department's 'Guide: Applying for a Subdivision (Tentative Parcel Map or Tentative Tract Map) and Signature Page' (rev. 1/17/25), confirmed via pdftotext extraction. It walks through the pre-application-meeting requirement, online portal (acpermit.acgov.org), and hearing/appeal process rather than a line-item document checklist.
Single-sourced to the Planning Dept subdivision application guide itself (extracted via pdftotext); could not find a separate current fee-resolution PDF corroborating the $4,000 figure independently. Planning Dept confirmed by phone at (510) 670-5400 as the number to call for current deposit amounts; PWA Development Section handles the subsequent Parcel/Tract Map review at (510) 670-6601 under a separate fee.
Verified directly from the Clerk-Recorder's official fee schedule (effective 1/1/2024, still current as of this search) via pdftotext extraction — line items 'Maps (1st page) $83.00 / GC 27372' and 'Maps (Each additional page) $2.00 / GC 27372'. Corroborated by an independent 2023 fee-schedule search snippet also citing $83.00 for the first page. Note this map-specific fee (GC 27372) is separate from the standard document recording fee ($89 first page + $75 SB2 fee) that applies to deeds/liens.
City of Oakland
Tentative parcel maps: Oakland Municipal Code, Title 16 (Subdivisions), Chapter 16.08 (Tentative Maps) governs Tentative Parcel/Tract Map approval; Chapter 16.24 (Parcel Maps) governs the final Parcel Map that divides the property.
Submittal checklist →Checklist ('Tentative Parcel Map Supplemental Submittal Requirements,' updated August 2025) confirmed via pdftotext — requires obtaining a Parcel Map Number from the Alameda County Recorder's Mapping Division ((510) 208-9857), a digital copy of the Tentative Parcel Map, and lists required map content (datum, north arrow, easements, parcel dimensions, etc.). A separate companion application/checklist for the final Parcel Map or Tract Map ('Application for Parcel Map or Tract Map,' DOT Engineering Services) was also verified via pdftotext at https://cao-94612.s3.amazonaws.com/documents/Application-for-Parcel-Map-PM-Permit-or-Tract-Map-TM-Permit.pdf.
Extracted via pdftotext from the City's official Zoning Fee Schedule 2025-2026 (dated 9/18/2025), retrieved through the Wayback Machine after the live oaklandca.gov URL returned HTTP 403 to automated fetches (likely bot-blocking, not a broken link — the same file is linked from the live Planning & Building fee-schedule page). Single-sourced; no independent second document corroborating this exact total was found. Separate 'Application for Tentative Tract Map/TTM (5+ lots)' and 'Application for Parcel Map Waiver' fee lines also exist on the same schedule at different totals.
Oakland is within Alameda County and does not have its own Recorder; final Parcel/Tract Maps are recorded with the Alameda County Clerk-Recorder in Oakland (1106 Madison Street). The City's own submittal instructions direct the applicant's Land Surveyor and title company to coordinate directly with the County Recorder for Mylar map recording.
