Subdivision & Tentative Parcel Map Requirements
Municipal code citations, submittal checklists, and fees for the county and its largest city.
Mariposa County
Tentative parcel maps: Mariposa County Code Title 16 - Subdivisions. Minor land divisions (4 lots + remainder or less) are processed as Tentative Parcel Maps; major subdivisions (5+ lots) use Chapter 16.20 (Major Subdivision Requirements). Section 16.12.100 requires all land divisions (minor and major) to be field-marked with signage prior to review. Full chapter text confirmed via Mariposa County DocumentCenter posting of "16-20 MAJOR SUBDIVISIONS REQUIREMENTS" (https://mariposacounty.org/DocumentCenter/View/3296/16-20-MAJOR-SUBDIVISIONS-REQUIREMENTS).
Submittal checklist →The live Municode-hosted book (mariposa.municipalcodeonline.com) lists ordinances but its Title 16 text did not render through automated fetch; section numbers (16.12.100, Chapter 16.20) are corroborated instead through two County-published PDFs: the Land Division Info Sheet package and the standalone Chapter 16.20 document on the County's own DocumentCenter. The Land Division Info Sheet (2026 rev., 9 pages) doubles as the de facto tentative parcel map / land division submittal checklist — verified by downloading and running pdftotext on the PDF directly since WebFetch could not parse the binary stream.
Verified by downloading the County's official 2025 Planning Fee Schedule PDF and extracting text with pdftotext (WebFetch could not parse the compressed PDF stream directly). This is the Planning Department's own current fee-schedule document, so it is authoritative, but I could only locate this single official source stating the dollar figures — the Land Division Info Sheet (https://mariposacounty.gov/DocumentCenter/View/97795/241028-Land-Div-Info-Sheet-Package) corroborates that fees are deposit-based and billed at $130/hr but does not restate the dollar amounts, so treat the specific figures as single-sourced.
Primary source is the County Recorder's own Fee Schedule page, which explicitly separates 'Maps: Subdivision, Parcel, Survey, and Assessment' ($9/$2) from general documents ($14/$3). A second County page (List-of-Services-and-Costs) and deeds.com's summary of the County schedule both corroborate the general $14/$3 document rate, but neither independently restates the map-specific $9/$2 rate, so the map rate itself is single-sourced to the Recorder's official fee page.
Mariposa
Mariposa County has zero incorporated cities — Mariposa (the county seat) is an unincorporated CDP served entirely by Mariposa County government; there is no separate municipal code, planning department, or fee schedule for the town itself. A separate 'Mariposa Town Planning Area (TPA)' overlay exists within the County's subdivision ordinance with its own land-division standards, but it is administered by the County Planning Department, not a city government.
