Municipal code citations, submittal checklists, and fees for the county and its largest city.
San Luis Obispo County
Tentative parcel maps: Title 21 (Real Property Division), Chapter 21.02 (Applications, Content, Processing and Time Limits), § 21.02.046 "Contents of tentative parcel and tract maps"
Submittal checklist →Title 21 is the county's Real Property Division Ordinance (implements the Subdivision Map Act) and is hosted on Municode Library. Section 21.02.046 is corroborated by a second mirror (slocounty-ca.elaws.us/code/cc_title21_ch21.02_sec21.02.046), which returned an error on direct fetch but appeared in search snippets confirming the section title and chapter. The checklist page (Planning & Building 'Tentative Parcel Map' service page) points to a downloadable 'Land Division – Checklist & Application Package'; the exact PDF file URL could not be resolved because the destination link is JS-obscured on the page, so the checklistUrl given here is the service page that hosts the download link, not the PDF itself.
Verified by downloading the county's official 'Comprehensive Fee Schedule FY 2025-2026' PDF (effective July 1, 2025) and extracting text with pdftotext — row 'S20 Parcel Map' lists $10,756.00 + $957.28 TSF = $11,713.28, with additional Public Works/Env. Health columns. Single-sourced: I could not locate a second independent document (e.g., a Board of Supervisors fee-resolution staff report) restating this exact figure within the time available; the county's Public Works fee schedule PDF (public-works-fee-schedule-2025-26-eff-7-1-25) was found but returned an HTML wrapper page instead of extractable PDF text, so it could not be used to corroborate the Public Works portion of the fee.
Figure returned directly from the Clerk-Recorder's official fee schedule page (titled 'Fee Schedule Effective July 1, 2026, through June 30, 2027' at this URL despite the legacy '2024' slug). Single-sourced — a second corroborating document (e.g., a Board resolution PDF) was not independently pulled and verified in this session.
City of San Luis Obispo
Tentative parcel maps: San Luis Obispo Municipal Code, Title 16 (Subdivisions), Chapter 16.08 (Types of Maps Required), § 16.08.050 "Tentative parcel maps" (see also Ch. 16.14, Parcel and Final Maps, for map form/contents/recordation)
City subdivision ordinance is Title 16 of the Municipal Code, mirrored on sanluisobispo.municipal.codes (a Municode-family site). A specific tentative-parcel-map submittal checklist PDF could not be confirmed — the City's fee/document pages (slocity.org) are behind Akamai bot protection and returned 403/Access Denied on every direct fetch attempt in this session, so checklistUrl is omitted rather than guessed.
The City of San Luis Obispo has no separate Recorder — recordation of final/parcel maps for city subdivisions is handled by the County Clerk-Recorder per state law (Gov. Code map recordation requirements), so the county's per-page fee applies.
