Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Humboldt County
Tentative parcel maps: Title III (Land Use and Development), Division 2 (Subdivision Regulations), Chapter 3 "Tentative Subdivision Maps" (§§ 323-1 through 323-6); parcel map specifics at Chapter 6, Article IV "Parcel Map" (§§ 326-30 through 326-34)
Submittal checklist →Verified live on General Code's humboldt.county.codes platform (current through Ord. 2784, passed 3/10/2026 per page footer). Checklist PDF confirmed via pdftotext extraction — titled 'PLOT PLAN AND TENTATIVE MAP CHECKLIST', linked from the Planning Division Forms & Handouts page (https://humboldtgov.org/3363/Planning-Division-Forms-Handouts).
Extracted directly from the PDF text (WebFetch could not render it — pdftotext -layout was used on the downloaded file). Line item: 'Subdivision ( Parcel Map - PMS) $5,200.00', effective 2/16/2026. Single-sourced to this official fee schedule; did not find a second independent corroborating document restating this exact figure (an older FY2019-20 schedule exists at a different URL but has since been superseded, so it isn't a valid corroboration of the current amount).
Recorder fee schedule states 'All Fees Effective as of January 1, 2022 ... Revised 11/2021 (no change as of 1/1/2024)'. This document is still the one actively linked from the live Clerk-Recorder page (https://humboldtgov.org/244/Clerk-Recorder) as of 2026-07, which corroborates it is current. No separate itemized 'parcel map' recording line was found (maps are recorded under the standard per-page fee plus the state-mandated $10/page Survey Monument Fund fee under PRC 8771).
City of Eureka
Tentative parcel maps: Eureka Municipal Code, Chapter 154 "Subdivision Regulations" — provisions applicable to tentative parcel maps include § 154.071 "Form and Contents"
amlegal.com blocks automated fetches (403) so the exact subchapter breakdown for tentative maps within Chapter 154 could not be fully confirmed beyond section titles surfaced in search snippets (§154.003 Conformity to General Plan, §154.005 Modification of Requirements, §154.071 Form and Contents, §154.175 Amendment by Certificate of Correction). Recommend a human confirm the precise tentative-map subchapter (likely §§154.070-154.075) directly on codelibrary.amlegal.com or library.municode.com/ca/eureka. No dedicated tentative-map submittal checklist PDF was found on eurekaca.gov; omitted checklistUrl as a gap rather than guessing.
City of Eureka Schedule of Fees and Service Charges, Fiscal Year 2025-26 (extracted via pdftotext after WebFetch failed to render the PDF text). Two separate fee line items apply — a Planning land-division processing fee and a separate Public Works/Engineering plan-check fee — both appear in the same official document, so this is corroborated within one authoritative source but not by a second independent document.
Eureka has no separate municipal Recorder; recordation of maps within city limits still occurs at the county Recorder per Government Code map-recording authority.
