17.3 Subdivision Map Act Maps and Certificates

Domain V professional activity 7 lists records of survey, corner records, lot line adjustments, subdivision maps, condominium plans, and LAFCO as State-regulated products. Knowledge items W through AA ask for legal content of tentative, parcel, and final maps, certificates of compliance, and certificates of correction and amended maps. Signing and sealing sit in knowledge item R and in 16 CCR 411. Independent OpenExamPrep teaching stays at published Government Code and Board-rule content. Local application checklists vary; they do not authorize invented statewide form fields.

Tentative maps: design, not a recorded survey

Government Code 66424.5(a) : a tentative map is made to show the design and improvement of a proposed subdivision and the existing conditions in and around it and need not be based upon an accurate or detailed final survey of the property. 66424.5(b) : a vesting tentative map meets 66424.5(a) and 66452. 66452(a) files the tentative map with the clerk of the advisory agency, or of the legislative body if there is no advisory agency, or with another officer designated by local ordinance. 66452(c) : at filing, a vesting tentative map shall have printed conspicuously on its face the words "Vesting Tentative Map." That printed legend is legal content, not decoration.

A tentative map is a planning instrument. It is not the ROS substitute, and it is not the recorded parcel or final map.

Which map: 66426, 66428, and parcel versus final

Government Code 66426 requires a tentative and final map for subdivisions creating five or more parcels, five or more condominiums (Civil Code 783), a community apartment project containing five or more parcels, or conversion of a dwelling to a stock cooperative containing five or more dwelling units, except where:

• The land before division contains less than five acres, each parcel abuts a maintained public street or highway, and no dedications or improvements are required.
• Each parcel has a gross area of 20 acres or more and approved access to a maintained public street or highway.
• The land has approved access and is part of a tract zoned for industrial or commercial development, with governing-body approval of street widths and configuration.
• Each parcel has a gross area of not less than 40 acres or is not less than a quarter of a quarter section.
• The land is solely an environmental subdivision under 66418.2.

For those listed exceptions, 66426(f) requires a parcel map. 66428 separately requires a parcel map for subdivisions as to which a final or parcel map is not otherwise required, unless waived by local ordinance under the findings 66428(b) lists (area, improvement and design, drainage, roads, sanitation, water, environmental protection, and other Map Act or local-ordinance requirements). Local ordinances may require a tentative map where a parcel map is required. A parcel map is not required for specified short-term railroad operating right-of-way leases under 66428(a)(1).

Parcel map legal content: 66445

66445 : a parcel map shall be prepared by, or under the direction of, a registered civil engineer or licensed land surveyor, shall show the location of streets and property lines bounding the property, and shall conform to the article's provisions, including:

• Sheet size 18 by 26 inches (460 by 660 mm), one-inch blank margin, scale large enough to show details, sheet numbers and relationships (66445(b)).
• Each parcel numbered or lettered; blocks may be numbered or lettered; each street named or otherwise designated; subdivision number shown with a description of the real property being subdivided (66445(c)).
• Subject to 66436, a statement signed and acknowledged by all parties having any record title interest, consenting to preparation and recordation, except that less inclusive requirements may be provided by local ordinance (66445(e)).
• Local agencies may put those statements on a separate instrument recorded concurrently (66445(f)); if so, the map references the separately recorded document, completed by the recorder under 66468.1 (66445(h)).
• On and after January 1, 1987, no additional survey and map requirements that do not affect record title interests belong on the parcel map; the map instead contains a notation of reference to survey and map information required by local ordinance under 66434.2 (66445(g)).
• If a field survey was performed, a statement by the engineer or surveyor that all monuments are of the character and occupy the positions indicated, or will be set on or before a specified date, and that the monuments are or will be sufficient to enable the survey to be retraced (66445(i)).

Parcel maps therefore can be compiled in some jurisdictions without a new field survey, but when a field survey was performed, 66445(i) is required legal content. Do not invent extra certificate titles beyond 66445 and locally authorized 66443-style additions.

Final map legal content: 66433–66436, 66443

66433 : content and form of final maps are governed by that article. 66434 : the final map shall be prepared by or under the direction of a registered civil engineer or licensed land surveyor, shall be based upon a survey, and shall conform to the listed provisions, including permanent-record media in black on tracing cloth or polyester base film (66434(a)); 18-by-26-inch sheets with a one-inch blank margin (66434(b)); all survey and mathematical information necessary to locate all monuments and to locate and retrace interior and exterior boundary lines, including bearings and distances, curve radii and arc or chord data, curve-center information, and ties to existing monuments used to establish the subdivision boundaries (66434(c)); parcel and street identifiers plus subdivision number and description of the real property (66434(d)); a distinctive exterior boundary that does not include a 66424.6 designated remainder or omitted parcel, which must be labeled as such, plus the definite location of the subdivision and its relation to surrounding surveys (66434(e)); and delineation of public streets or public easements left in effect, with the filing of the final map constituting abandonment of public streets and easements not shown, if a written notation lists recording data and the clerk or designee certifies the abandonment on the map (66434(g) — other-entity easements need notice and may not be abandoned as provided there).

66436 requires a signed, acknowledged consent statement from parties with record title interest, with listed omissions (including certain easements that cannot ripen into a fee, and original United States or State patent reserved interests). 66443 allows additional certificates required by local ordinance. BPC 8765(c) then exempts a separate ROS when a Subdivision Map Act map is in preparation or recorded — the final or parcel map is the public survey record for that division, not a second 8762 map of the same lots.

Lot line adjustments: 66412(d)

Government Code 66412(d) excepts from the Map Act a lot line adjustment between four or fewer existing adjoining parcels, where land taken from one parcel is added to an adjoining parcel, and where a greater number of parcels than originally existed is not thereby created, if approved by the local agency or advisory agency. Review is limited to whether resulting parcels conform to the local general plan, applicable specific plan, applicable coastal plan, and zoning and building ordinances. Conditions or exactions are limited to those conformity items, prepayment of real property taxes, or facilitating relocation of existing utilities, infrastructure, or easements. No tentative map, parcel map, or final map shall be required as a condition of approval. The adjustment shall be reflected in a deed, which shall be recorded. No record of survey shall be required unless required by BPC 8762. Approval or disapproval proceeds under the Permit Streamlining Act. Exam trap: calling a five-parcel reconfiguration a 66412(d) adjustment, or telling a client that 66412(d) repeals 8762 when new lines are not of record.

Certificates of compliance: 66499.35

66499.35(a) : any owner, or a vendee under a contract of sale, may request a determination whether the real property complies with the Map Act and local ordinances enacted pursuant to it. If it complies, the city or county shall cause a certificate of compliance to be recorded identifying the real property and stating that the division complies. A reasonable fee may cover issuance and recording. 66499.35(b) : if it does not comply, the agency shall issue a conditional certificate of compliance, may impose conditions that would have applied at the time the applicant acquired the interest (or, for the owner who created the illegal division and still owns a resulting parcel, conditions applicable to a current division), and records the conditional certificate as notice that those conditions must be fulfilled before a development permit. Compliance with the conditions is not required until a permit or other grant of approval for development is issued. 66499.35(c) issues a certificate for property approved for development under 66499.34. 66499.35(d) : a recorded final map, parcel map, official map, or approved certificate of exception already constitutes a certificate of compliance for the parcels described. 66499.35(e) treats certain official maps under 66499.52(b) the same way.

66499.35(f)(1) lists information the local agency deems necessary, including but not limited to:

• (A) Name or names of owners.
• (B) Assessor parcel number or numbers.
• (C) Number of parcels for which the certificate is issued and recorded.
• (D) Legal description of the parcel or parcels.
• (E) The statutory notice that the certificate relates only to Map Act and local-ordinance compliance, that the parcel may be sold, leased, or financed without further Map Act compliance, and that development may require permits.
• (F) Any conditions to be fulfilled before a development permit, as specified in a conditional certificate.

Multiple parcels may share one recorded certificate if descriptions are clearly identified and distinguished (66499.35(f)(2)). Do not add unpublished owner-application blanks as if they were statewide 66499.35 fields.

Certificates of correction and amending maps: 66469–66472.1

66469 allows amendment of a recorded final or parcel map by certificate of correction or amending map to correct a course or distance error; show an omitted course or distance; correct an error in the description of the real property; indicate monuments set after death, disability, retirement, or replacement of the engineer or surveyor charged with setting them; show the proper location or character of a monument that was shown wrong; correct 66434.2 additional information if the correction does not burden present fee owners or alter record title; or correct other map errors or omissions approved by the county surveyor or city engineer that do not affect any property right (examples: lot numbers, acreage, street names, identification of adjacent record maps). "Error" does not include changes in courses or distances from which an error is not ascertainable from the data shown on the map. You cannot "correct" a boundary into a new location with a certificate of correction.

66470 : the amending map or certificate of correction shall be prepared and signed by a registered civil engineer or licensed land surveyor. An amending map shall conform to 66434 if a final map, or to 66445(a)–(d) and (f)–(i) if a parcel map. It shall set forth the corrections in detail and show the names of the fee owners of the affected real property on the date the original map was filed or recorded. After recordation, the recorder transmits a certified copy to the county surveyor or engineer, who maintains an index.

66471 : the county, city surveyor, or city engineer examines the instrument; for a certificate of correction, that office has 20 working days to examine for compliance with 66469 and 66470, endorse, and present it to the recorder, or return it with required changes; after resubmission and approval, 10 working days to present it for recordation.

66472.1 is the separate, ordinance-authorized path to modify map conditions after recording when circumstances change, the modifications do not impose additional burden on fee owners, do not alter record title interests reflected on the map, and the modified map conforms to 66474, after a public hearing confined to the proposed modification. That is not a stealth lot-line change.

BPC 8770.5 lets a filed ROS be amended in the same manner subdivision maps may be amended under the Map Act, for omitted courses or distances and listed minor errors approved by the county surveyor.

Condominium plans and LAFCO maps

Government Code 66427 : a map of a condominium project, community apartment project, or specified stock-cooperative conversion need not show the buildings or how buildings or airspace are divided, and need not include a condominium plan as defined in Civil Code 4120 or 6540. The governing body may not refuse the parcel, tentative, or final map for absence of a condominium plan. Fees and lot-design requirements are computed from surface lots. After an approved parcel or final map for condominiums, separating three-dimensional portions into condominiums is not a further subdivision if the authorized condominium count is not increased, among other 66427(e) conditions.

Civil Code 4285 states condominium-plan legal content: (a) a description or survey map of the project that refers to or shows monumentation on the ground; (b) a three-dimensional description identifying the common area and each separate interest, which may extend an indefinite distance upward or downward; (c) a certificate consenting to recordation, signed and acknowledged as provided in Civil Code 4290. 4290 requires signatures of fee owners, lessors and lessees of a terminating estate for years, life tenants and remainder interests, and each recorded deed-of-trust trustee or beneficiary and mortgagee; owners of mineral rights, easements, rights-of-way, and other nonpossessory interests need not sign.

LAFCO maps implement changes of organization and reorganization under the Cortese-Knox-Hertzberg Local Government Reorganization Act (Government Code Title 5, Division 3). The statewide duty is a definite map and geographic description of the affected territory for commission action and later State Board of Equalization tax-rate-area work, prepared by a person authorized to practice land surveying. Sheet size, north-arrow blocks, and certificate wording are set by local LAFCO procedures and Board of Equalization mapping standards, which are not a single PLS Act form. Do not treat a county's 8.5-by-11 or 18-by-26 handout as unpublished "statewide" fields. Seal the description and map under BPC 8761 and 16 CCR 411; expect county surveyor technical review before a commission hearing.

Signing and sealing: BPC 8761 and 16 CCR 411

BPC 8761(b)–(d) : land-surveying documents are prepared by or under the responsible charge of an authorized licensee and include name and license number. Interim documents need a purpose notation such as "preliminary" or "for examination only." Final maps, plats, reports, descriptions, and other land-surveying documents shall bear signature, seal or stamp, and date. On multiple pages, those elements appear at a minimum on the title, cover, or signature sheet unless otherwise required by law (ROS 8764.5 statements are an example of a more specific face-of-map rule). 8761(f) forbids sealing after the named certificate has expired, been suspended, or been revoked unless renewed or reissued.

16 CCR 411(b) : the land surveyor seal authorized by BPC 8750 is not less than one and one-half inches in diameter, with "Professional Land Surveyor" or "Licensed Land Surveyor" in the top border, "State of California" in the bottom border, and the licensee's name and certificate number in the center. 411(d) allows an abbreviated given name if the surname listed with the Board appears on both seal and signature. 411(e) allows permanent ink, impression, or electronically generated seal representations and electronic signatures. 411(f) prohibits preprinting blank forms with the seal or signature, decals of seal or signature, and a rubber stamp of the signature. 411(g)(2) : maps, plats, reports, descriptions, or other professional land-surveying documents shall be signed and sealed so all work can be clearly attributed to the licensee in responsible charge. 411(g)(3) : two or more responsible-charge licensees each sign and seal with a notation describing the work done under each. 411(h) : include the date of signing and sealing immediately below or next to the signature and seal.

Worked example. A client wants to move a fence line between two existing lots and "just file a parcel map." If the facts are four or fewer adjoining parcels, no extra parcel created, and local 66412(d) approval, the Map Act vehicle is a recorded deed, not a tentative/parcel/final map. If the new line is not of record, BPC 8762 may still demand an ROS. A buyer of an old illegal split requests marketable-parcel paper: 66499.35 is a certificate or conditional certificate, and a recorded 1985 parcel map already is a certificate of compliance for lots it describes. A five-lot residential cut needs a tentative map (design, no final survey required) and later a final map based upon a survey with 66434 math, 66436 owner statements, and 16 CCR 411 seals dated next to the signatures.
