Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Los Angeles County
Tentative parcel maps: LA County Code Title 21 (Subdivisions), Chapter 21.40 "Tentative Maps" governs tentative parcel/tract maps generally; parcel-map-specific procedures for 4-or-fewer-parcel divisions are cross-referenced from Chapter 21.06 (Definitions) and Chapter 21.44 (Final Maps). Confirmed live on Municode at nodeId TIT21SU_CH21.40TEMA.
Submittal checklist →Checklist PDF (form 00263A, revised 11/26/2025) is the Dept. of Regional Planning's 'Subdivisions Application Checklist,' filed via EPIC-LA (epicla.lacounty.gov). Verified by direct curl + pdftotext, not just search snippet.
Verified by downloading the PDF (Dept. of Regional Planning 'Subdivision Fees Table,' effective March 1, 2026) and extracting text with pdftotext -layout — single primary source found (the official current fee resolution itself); no separate second document restates this exact total, so treat as single-sourced from the authoritative fee table.
Verified via curl + pdftotext of DPW's official fee notice (effective July 1, 2026, CPI-adjusted annually). This document only itemizes the Record of Survey fee table; the general Recorder base-fee bulletin (lavote.gov, Rev 4/1/2022) confirms the $15/$3-per-page pattern for standard documents but does not separately itemize maps, so the map-specific $13/$3 figures are single-sourced to the DPW notice. Contact Brett Silva (626) 458-5127 / bsilva@dpw.lacounty.gov for confirmation.
City of Los Angeles
Tentative parcel maps: LAMC Chapter 1, Article 7, "Division of Land Regulations" — Sec. 17.50 "Parcel Maps – General Provisions" governs parcel maps (4 or fewer parcels); Sec. 17.01 covers Tract Maps (5+ parcels). Confirmed via search results returning both amlegal.com section pages directly (direct WebFetch blocked by 403 bot protection, but Google-cached search snippets and the permitmanual.engineering.lacity.gov cross-references corroborate the section numbers).
Submittal checklist →This CP-6110 checklist is specifically for Tentative Tract Maps (5+ parcels); a parallel parcel-map (4-or-fewer) filing instructions document exists on the same planning.lacity.gov odocument path per Bureau of Engineering's 'Technical Procedures 01 - Tentative Subdivisions' page (https://permitmanual.engineering.lacity.gov/land-development/technical-procedures/01-tentative-subdivisions) but a dedicated parcel-map-only checklist URL could not be independently confirmed — only single-sourced to the tract-map checklist as the closest verified document.
Single-sourced to search-result summaries of the Comprehensive Fee Update page and LAMC Sec. 19.02/11.12 references; WebFetch was blocked (403) on the actual LAMC fee-section text and the interactive Fee Estimator tool, so no exact dollar amount is reported here — flagged in gaps.
