Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Sierra County
Tentative parcel maps: Sierra County Code, Title 23 (Subdivision Regulations), Chapter 23.09, § 23.09.020 'Tentative parcel map required' (final parcel map provisions at § 23.10.010)
Submittal checklist →Sierra County Code is hosted on the General Code / county.codes platform (not Municode) at https://sierra.county.codes/, current through Ord. 1143 (Feb 17, 2026), per site search result. Verified § 23.09.020 exists and is titled 'Tentative parcel map required' via direct fetch of the code page. The 'checklistUrl' is the county's Tentative Parcel Map application form/instructions PDF (titled 'Tentative Parcel Map' in the Planning DocumentCenter) — a separate standalone 'submittal checklist' document was not found; the application PDF itself doubles as the submittal requirements list. A newer 'Tentative Parcel Map Application 2026' form is also linked from the Planning Application Forms page (https://sierracounty.ca.gov/403/Planning-Application-Forms) as /DocumentCenter/View/11763/Tentative-Parcel-Map-Application-2026.
Corroborated by two sources: the Planning Fees page (live fetch) and the official County Master Fee Schedule PDF (Schedule J — Planning Department), https://www.sierracounty.ca.gov/DocumentCenter/View/7669/County-Fee-Schedules, which lists 'Parcel Map Subdivisions', 'Parcel Map Waivers', and 'Parcel Mergers' as deposit-based applications billed at $65/hour (quarter-hour increments) after a $100 nonrefundable initial review fee, per Resolution 2018-024 (Master Fee Schedule) as amended. There is no separate flat 'tentative parcel map fee' — Sierra County runs 100% actual-cost-recovery deposit accounting for planning entitlements.
Double-verified: (1) County Master Fee Schedule PDF, Clerk-Recorder Schedule D, 'Recording of Maps: First Page $6.00 (GC 27372), Each Additional Page $2.00'; (2) the Clerk-Recorder's own current 'Schedule of Fees (Effective Jan 1, 2026)' PDF at https://www.sierracounty.ca.gov/DocumentCenter/View/6485/Schedule-of-Fees-01-01-22 (filename is stale but content is dated effective 1/1/2026), which states 'Recorder's Fees ... $6 First Page; $2 Second Page Survey Maps; $250 CD Survey Maps.' Note the county's general (non-map) document recording fee is separately $14 first page / $3 additional per the master schedule, rising to $15 first page effective March 1, 2026 per the Recorder's page (https://www.sierracounty.ca.gov/220/Recorder) — that increase applies to regular documents, not confirmed to apply to the GC 27372 map-specific fee.
