Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Lake County
Tentative parcel maps: Code of Ordinances, Chapter 17 - Subdivision Regulation (Lake County adopted its Subdivision Ordinance under this chapter, implementing the Subdivision Map Act; tentative parcel maps for 4-or-fewer-lot divisions are processed under this chapter). Municode's viewer is a JS application that blocks scripted fetches, so the specific article/section number within Chapter 17 for tentative parcel maps could not be confirmed beyond the chapter level in this pass — verify the exact subsection live at the URL above.
Live Municode chapter link confirmed (HTTP 200, chapter title verified as 'SUBDIVISION REGULATION'). Chapter-level citation only; sub-section number not independently verified due to Municode's Angular SPA blocking automated content extraction.
Verified via direct PDF download + pdftotext (Master Fee, Cost Recovery Schedule, effective 7/1/2025). Figure is double-corroborated within the same official document: the summary 'Subdivision' fee table lists a $146 Tentative Parcel Map intake fee, and the itemized cost-recovery table later in the same document lists the full ~$2,730 deposit breakdown by department. No independent second document (e.g., a separate BOS resolution PDF) was found to cross-check against.
This is a scanned PDF; text extracted via OCR (tesseract) since it has no embedded text layer. Document is titled 'County of Lake Recorder's Office Schedule of Charges,' effective January 1, 2026 — a single primary source (the Recorder's own published fee schedule); no second corroborating source located.
City of Clearlake
Tentative parcel maps: Clearlake Municipal Code, Chapter XVI (Land Subdivision), Article I - General, §16-1.1 adopts Lake County Code Chapter 17 (Subdivision Regulation) by reference for the City; §16-2 (General Provisions) covers parcel map mergers, resubdivisions (4 or fewer parcels), and lot line adjustments, including application contents (§16-2.5) and fees (§16-2.6). Article II (§16-8 through §16-10) is a separate Vesting Tentative Map Ordinance for applicants who elect vesting-map processing.
Verified live via clearlake.municipal.codes (CivicPlus-hosted, current through Oct. 2019 per site banner, with a 'Recent Updates' folder for anything codified after — confirm no newer ordinance amendments before relying on section numbers). Per §16-2.8, approved parcel maps/instruments are delivered to the County Recorder for recording, confirming Clearlake routes recording to Lake County's Recorder rather than maintaining its own.
Verified via direct PDF download + pdftotext ('City of Clearlake Fee Schedule,' effective July 1, 2024). Only one source located — no second corroborating document (e.g., a council staff report) was found restating these figures, so this is single-sourced.
Clearlake does not operate its own recording office; final/parcel maps are recorded through the Lake County Recorder, so the county recording fee schedule applies.
