Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Napa County
Tentative parcel maps: Napa County Code of Ordinances, Title 17 (Subdivisions), Chapter 17.08 (Contents/Filing/Processing of Tentative Maps), §§17.08.020, 17.08.030, 17.08.040, 17.08.050 — tentative map form, content, and processing requirements. Chapter 17.22 covers Parcel Maps specifically; Chapter 17.20 covers Final Maps.
Submittal checklist →Checklist confirmed via direct PDF text extraction — titled 'TENTATIVE PARCEL MAP AND TENTATIVE SUBDIVISION MAP APPLICATION PACKET' from Napa County Planning, Building, and Environmental Services, and its own 'Land Division Application Completeness Checklist' cites the same 17.08.xxx sections, corroborating the ordinance citation. Municode chapter subsection titles (e.g. Ch. 17.08, 17.20, 17.22) were found via Google-cached search snippets; the live Municode page itself returned a JS-rendered shell (403/blocked to automated fetch), so exact chapter title wording could not be independently re-confirmed by direct fetch — only the chapter numbers and cross-referenced section numbers are double-sourced.
Line item 'Land Division: Tentative Map (Parcel or Subdivision)' in Napa County Fee Resolution Part 80 (Planning & Conservation), effective 07/01/2026, verified by downloading the PDF and extracting text with pdftotext. Single-sourced for the exact dollar figures — the county's own tentative-map application checklist PDF corroborates that a fee deposit is required at pre-application but does not restate the dollar amount, so that is not full double-verification of the number itself. Distinct from the separate County Surveyor/Public Works 'Final parcel map filing' map-check fee ($184/hr, $8,000 deposit, Fee Resolution Part 140) charged later at final map stage.
From the Napa County Recorder-County Clerk (John Tuteur) Fee Schedule, effective July 1, 2026, verified via pdftotext extraction of the PDF; the schedule separately lists standard document recording ($15 first page/$3 additional) vs. a distinct 'MAP FILING' line item ($8/$2) used for parcel/final maps. Single-sourced — no second independent restatement of this specific map-filing fee was found.
City of Napa
Tentative parcel maps: City of Napa Municipal Code, Title 16 (Subdivisions), Chapter 16.20 — Tentative Maps (governs Tentative Parcel Maps and Tentative Subdivision Maps; per NMC §16.20.090, tentative maps expire 24 months after approval, consistent with Gov. Code §66452.6). Chapter 16.12 covers Subdivision Maps Generally; Chapter 16.24 covers Final Maps.
Submittal checklist →Checklist confirmed by direct PDF extraction — 'TENTATIVE MAP Submittal Requirements' from City of Napa Planning Division, listing application types 'Tentative Subdivision Map / Vesting Tentative Map / Tentative Parcel Map.' A second, engineering-focused 'Subdivision Map Checklist' (final map plan-check items) is at https://www.cityofnapa.org/DocumentCenter/View/839/Subdivision-Map-Checklist-PDF and was also verified by PDF extraction (Public Works Engineering Division, Nov. 2019). Chapter 16.20 title 'TENTATIVE MAPS' corroborated across two independent mirrors of the same code (ecode360.com and qcode.us search-result titles), though both live hosts return JS-challenge pages to automated fetch, so full chapter text could not be re-extracted directly.
Stated directly on the City's Tentative Map submittal-requirements form: 'Fee/Initial Deposit - City Fee Schedule charges staff time and materials. The initial deposit is $5,000, check payable to City of Napa.' Single-sourced — the City's standalone consolidated fee-schedule page (cityofnapa.org/Archive.aspx, fee schedule effective dates 2021/2023) could not be located current for 2026 to independently corroborate the $5,000 figure.
The City of Napa does not maintain its own Recorder; final/parcel maps for City subdivisions are recorded at the Napa County Recorder-County Clerk's office under the same county Map Filing fee schedule listed above.
