Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Sonoma County
Tentative parcel maps: Sonoma County Code, Title V, Chapter 25 (Subdivisions), Article II - Parcel Map Procedures, Sec. 25-21 through 25-23 (tentative parcel map filing, processing, and 24-month recording deadline). Minor subdivisions (4 or fewer parcels) are processed as tentative parcel maps under this article; major subdivisions (5+) fall under Article I/III governing tentative (subdivision) maps.
Submittal checklist →Municode direct node URL returned HTTP 403 on live fetch (bot-blocked, not broken — confirmed via corroborating Google cache/search snippet quoting the same section 25-23 text about the 24-month filing deadline and tentative parcel map processing). Permit Sonoma's own overview page (https://permitsonoma.org/instructionsandforms/subdivision) restates the same ordinance citation and process, serving as the second source. Checklist is 'SUR-001 Parcel/Final Map Submittal Requirements Checklist,' published as an HTML instructions page (no separate PDF found) — verified live 2026-07.
Two corroborating PDFs both adopted by Board of Supervisors Ordinance No. 6554, effective 07/01/2026: the Planning fee schedule (Fees-2026-2027-Planning.pdf, line 'Subdivision Minor (at cost*, min. deposit) ... $6,174.00') and the Surveyor fee schedule (https://permitsonoma.org/Microsites/Permit%20Sonoma/Documents/Department%20Information/Fees/2026/Fees-2026-2027-Surveyor.pdf, line 'Minor Subdivision Map Review and Processing (at cost*, minimum deposit) ... $3,535.00'). Both downloaded and text-extracted via pdftotext to confirm figures. All fees are minimum deposits billed at actual cost, not flat fees.
Corroborated by a second source, deeds.com's Sonoma County recorder page, which quotes the identical fee schedule line: 'Maps [Government Codes 27372, 27361, 27397, & 27388.1] ... $9.00 $2.00 per additional page.' This map-specific fee is separate from the general document recording fee ($91 first page/$3 additional, or $14/$3 with a transfer-tax/SB2 exemption statement).
City of Santa Rosa
Tentative parcel maps: Santa Rosa City Code (eCode360), Title 19 - Subdivisions: Chapter 19-24 (Tentative Map Procedures) governs tentative maps generally; Chapter 19-32 (Parcel Map Procedures) specifically covers tentative and final parcel maps for minor subdivisions (4 or fewer parcels).
Submittal checklist →Chapter 19-32 confirmed live via WebSearch/WebFetch summary of ecode360.com content (application, review/distribution timelines, 24-month recording deadline with extension provisions). Checklist titled 'Parcel Map & Final Map Submittal Checklist,' linked from the city's official Final Maps & Parcel Maps page (https://www.srcity.org/527/Final-Maps-Parcel-Maps), serving as the second corroborating source for both the ordinance chapter and checklist link.
Downloaded the live Master Fee Schedule PDF (version V1, effective 07/01/2026, per Council-adopted schedule) and extracted text with pdftotext -layout. Line item: 'MINOR - TENTATIVE PARCEL MAP [10] ... $10,446.28' under Planning Application Fees > Subdivision. Corroborated by a second copy of the identical PDF hosted at https://www.srcity.org/DocumentCenter/View/16129 (linked from the city's Final Maps & Parcel Maps page as the 'PED Fee Schedule') — same file, same figures, confirming it is the current, actively-linked schedule rather than a stale duplicate.
City's own Final Maps & Parcel Maps page states recording occurs at 'the County Recorder's Office' after City Engineer approval, subdivision agreement, and bonding — no city-level recording fee exists. Recording fee amount is the same county fee documented above, so no second independent source was needed beyond the county fee schedule already verified.
