Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Contra Costa County
Tentative parcel maps: Ordinance Code Title 9 (Subdivisions), Division 94 (Maps), Chapter 94-2 (Tentative Maps) — e.g. §94-2.802 'Approval of Tentative Maps'; parcel/final map recordation requirements follow in Chapter 94-4 (Final Maps and Parcel Maps)
Submittal checklist →checklistUrl is the county's 'Parcel Maps and Final Maps' checklist (revised 2023), published via the County Surveyor/Engineering Services FAQ page (contracosta.ca.gov/FAQ.aspx?QID=1186) — this is the map-check checklist used after tentative approval, not a dedicated tentative-map application checklist. A general 'Engineering Services Submittal Check List' (CL-1) also exists at https://www.contracosta.ca.gov/DocumentCenter/View/7960/CL-1-Submittal-Checklist-PDF but is not TPM-specific. Municode individual section pages (e.g. nodeId=...CH94-2TEMA_94-2.802APTEMA) return HTTP 403 to automated fetch, so the section citation above is corroborated via the Title 9 table-of-contents URL and Google-indexed search snippets of the chapter, not a direct render of the section text.
Land Development Fee Schedule adopted by the Board of Supervisors May 24, 2022, effective August 10, 2022 (still the posted current schedule as of verification). Single-sourced to this PDF — no second corroborating document found; the county's Land Development page (contracosta.ca.gov/436/Land-Development) references this same PDF as the authoritative schedule rather than restating amounts.
Corroborated by a second source, Deeds.com's Contra Costa County recorder page (https://www.deeds.com/recorder/california/contra-costa/), which independently states the same $9.00 first-page / $3.00 additional-page figures. Note an older PDF fee schedule under the previous recorder (Stephen L. Weir) shows a stale $7.00/$3.00 rate — do not use that superseded figure.
City of Concord
Tentative parcel maps: Concord Municipal Code Title 17 (Subdivisions), Chapter 17.10 'Subdivision Maps' — governs tentative maps/tentative parcel maps (locally termed 'minor subdivisions,' up to 4 lots, decided by the Zoning Administrator) and final/parcel maps; tentative map approval expires 24 months absent an extension
Submittal checklist →codepublishing.com returned HTTP 403 to automated WebFetch, so the section citation is corroborated via search-engine-indexed snippets of Chapter 17.10 rather than a direct page render. A companion 'Parcel Map Review Checklist' (post-tentative, pre-recordation) exists at https://www.cityofconcord.org/DocumentCenter/View/3157/Parcel-Map-Review-Checklist-, and Major/Minor Subdivision application checklists are linked from the Planning Permits page (cityofconcord.org/176/Planning-Permits).
This is the City's current Fees and Charges Schedule, Exhibit A to Resolution 78-6042, last adopted 4-28-2026 (Res. No. 26-6042.1), fee items 26.1.5 and 26.2.1-26.2.2. Single-sourced to this PDF — the city's Fee Schedules index page (cityofconcord.org/224/Fee-Schedules) links to it as the current schedule but does not restate the dollar figures itself, so no independent second source was found.
The county-recorder portion of this figure is corroborated by the two sources cited in the county recordingFee entry above (contracostavote.gov and deeds.com).
