Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Mono County
Tentative parcel maps: Mono County Code Title 17 (Subdivisions), Chapter 17.36 (Land Divisions); Planning Commission approval findings at § 17.36.090
Submittal checklist →Checklist URL is the Planning Division's 'Parcel Map/Land Division' application packet (revised Oct 2020), which includes the required Tentative Parcel Map Checklist. Chapter/section citation corroborated by two independent WebSearch snippets referencing Mono County Code § 17.36.090 approval findings, plus the Municode chapter listing (Chapter 17.36 - LAND DIVISIONS).
Verified live via curl+pdftotext: Consolidated Fee Schedule effective July 1, 2024 lists 'Parcel Map: Tentative — HOURLY — $135.00'. Corroborating (but older) second source: the Planning Division's permit_fees_01.13.pdf (dated 2013) shows a prior structure of a $495 initial deposit against an estimated 53 hours at $99/hr for 'Parcel Map: Tentative'. The two sources agree the fee is a cost-accounted/time-and-materials charge, not a flat fee, but the exact current up-front deposit amount (if any) could not be independently corroborated in the 2024 schedule — flagged in gaps.
Verified live via curl+pdftotext of the Clerk-Recorder's official Fee Schedule, effective July 1, 2025 (cites Gov. Code § 27361 authority). Single primary source — the Recorder's public fee-calculator page (monocounty.ca.gov/clerk/page/fee-calculator) generally corroborates the recording-fee structure but was not independently fetched with exact map-fee text, so this is not fully double-verified.
City of Mammoth Lakes
Tentative parcel maps: Town of Mammoth Lakes Municipal Code Title 16 (Subdivisions) governs the substantive subdivision/tentative-map standards; the Zoning Code (Title 17) Chapter 17.60 (Applications, Processing, and Fees), Table 17.60.030, sets the procedural review authority for Tentative Parcel Maps (Planning Commission decision, appealable to Town Council); § 17.60.130-area provisions address tentative map expiration (24 months)
Municode's live pages for Mammoth Lakes returned HTTP 403 to direct fetch (bot-blocked, but confirmed live via search-index snippets showing exact chapter/section numbers and titles). Independently corroborated Title 16 as the Town's actual subdivision ordinance by downloading and full-text-searching the Town's own Zoning Code Update document (townofmammothlakes.ca.gov/DocumentCenter/View/4469), which states at p. III-21: 'Tentative maps shall be conditioned in compliance with Title 16 (Subdivisions).' No dedicated public 'Tentative Parcel Map submittal checklist' PDF was found on the Town's Planning Permit Applications and Fees page — checklist field omitted, see gaps.
Verified live via curl+pdftotext of the Community & Economic Development Fee Schedule FY 2025-2026, linked from the Town's official Planning Permit Applications and Fees page. Single-sourced for the exact $6,000 figure — the FY24-25 Master Fee Schedule staff report describes the same cost-accounted/deposit methodology but its fee table was not machine-readable to confirm the prior year's dollar amount, so this is not independently double-verified.
Mammoth Lakes is Mono County's only incorporated town and has no separate town Recorder; all real property recording (including final/parcel maps) is done through the Mono County Recorder in Bridgeport.
