41 claims that get repeated about Bay Area home sales, each checked against a source and found not to apply. A checked claim is not the same as nothing applying — every entry names what was looked at and when. Where a jurisdiction does have a real requirement, it is on the list.
Alameda County
San Leandro
San Leandro requires a sewer lateral compliance certificate at sale, or is covered by EBMUD's program
NOT REQUIRED. The City of San Leandro's own FAQ states: "At this time, a sewer lateral compliance certificate is not required." It adds that the City may implement a sewer lateral ordinance in the future. San Leandro is NOT one of the communities in the EBMUD regional Private Sewer Lateral ordinance.
Why the claim spreads: San Leandro is inside EBMUD's water service area, so agents assume the EBMUD point-of-sale lateral ordinance applies. It does not — that ordinance names only Alameda, Albany, Emeryville, Oakland, Piedmont, El Cerrito, Kensington and the Richmond Annex.
Contra Costa County
Clayton
Clayton requires a sewer lateral inspection or certificate at point of sale
NOT REQUIRED. Clayton is served by Central Contra Costa Sanitary District, which states it has no point-of-sale sewer lateral inspection ordinance — an inspection before buying or selling is encouraged but not required. The property owner is responsible for the full lateral from building to main.
Why the claim spreads: Neighbouring Contra Costa jurisdictions (Richmond, San Pablo, Pinole, Hercules, Oakley) DO have point-of-sale requirements, so agents reasonably assume the whole county does.
Concord
Concord requires a sewer lateral inspection or certificate at point of sale
NOT REQUIRED. Concord is served by Central Contra Costa Sanitary District, which states it has no point-of-sale sewer lateral inspection ordinance — an inspection before buying or selling is encouraged but not required. The property owner is responsible for the full lateral from building to main.

Marin County
Corte Madera
Corte Madera requires a BESO energy audit before a home can be sold
NOT SUPPORTED. No time-of-sale energy audit ordinance was found for this town. Its energy ordinance is a reach code triggered by CONSTRUCTION, not by sale: Corte Madera's applies to "additions and alterations of 750 square feet of floor area" (being reduced to 500), and Tiburon's to "additions and alterations equal to or exceed 500 square feet of floor area in single family homes". Neither staff report contains the words sale, transfer, escrow or listing as a trigger. BESO is the City of BERKELEY's ordinance (Berkeley Municipal Code 19.81) and applies in Berkeley only. An independent industry roster of every California energy benchmarking and audit ordinance lists San Francisco, Berkeley, Los Angeles, San Jose and San Diego — and none of these three towns. Corte Madera does have a genuine residential resale report requirement — see that record. The energy claim is the false part.
Why the claim spreads: A widely-circulated county-by-county real-estate disclosure guide states that Tiburon, Sausalito and Corte Madera "must comply with BESO (Building Energy Saving Ordinance) audits prior to sale." It cites no ordinance number, and search engines now repeat the sentence back as fact. This is the same failure mode as the San Jose sewer lateral claim already in this dataset: an ordinance whose real trigger is renovation, relabelled as point-of-sale — and here compounded by borrowing another city's ordinance name.
Sausalito

Sausalito does have a genuine residential building report requirement and a Sausalito-Marin City Sanitary District lateral requirement — see those records. The energy claim is the false part.

Unincorporated Marin County
Marin County requires a resale inspection for homes in unincorporated areas
NOT REQUIRED. The Marin Association of REALTORS county disclosures advisory (§ 4.7, revised 2023-09-18) states: "Marin County currently does not require Seller to obtain a resale inspection for residential properties located in unincorporated portions of the County (although this may change), except for fire hardening and defensible space inspections, the necessity for which depends on the location of the property." The fire hardening/defensible space exception is the statewide AB 38 obligation already carried in this dataset, not a separate county resale inspection. A resale inspection can be obtained from the County voluntarily with the seller's consent.
Why the claim spreads: Several Marin towns DO mandate a resale inspection (Ross, Sausalito, Corte Madera, Belvedere), and unincorporated parcels routinely carry a town's mailing address, so the town's requirement gets attributed to the parcel. Whether a parcel is unincorporated is usually only settled by the preliminary title report.
San Mateo County
Belmont
Belmont requires a sewer lateral certification at point of sale
NOT AT POINT OF SALE. Belmont does require sewer lateral certification, but the trigger is renovations — not the sale of the property. Do not order a point-of-sale lateral certificate for a straightforward resale here.
Why the claim spreads: The city appears on 'cities requiring sewer lateral certification' lists without the trigger being read closely, so a renovation-triggered rule gets treated as a sale-triggered one.

Brisbane
Brisbane requires a sewer lateral certification at point of sale
NOT AT POINT OF SALE. Brisbane does require sewer lateral certification, but the trigger is renovations and meter size changes — not the sale of the property. Do not order a point-of-sale lateral certificate for a straightforward resale here.

Santa Clara County
Campbell
Campbell imposes a city-specific requirement — a resale report, energy audit or retrofit — that must be satisfied before a home sale closes
NONE FOUND. The Santa Clara County Association of REALTORS maintains the county's local-disclosure compilation, and it names a sale-triggered local requirement for only four jurisdictions: Morgan Hill (sewer lateral + water conservation fixtures), San Jose (rent ordinance, Ellis Act, street trees), Saratoga (sewer connection/septic report, occupancy inspection) and Sunnyvale (stormwater maintenance notice). Campbell is not among them. Two escrow/title presale-report charts covering 74 and 9 cities likewise name no Santa Clara County city. The statewide seller obligations still apply.
Why the claim spreads: Point-of-sale requirements are dense one county north — Alameda, Contra Costa, Marin and San Mateo all have several — so agents crossing county lines reasonably expect the same in Santa Clara County and go looking for a city report that does not exist.
Cupertino
Cupertino requires a sewer lateral certification at point of sale
NOT AT POINT OF SALE. Cupertino does require sewer lateral certification, but the trigger is renovations; the city performs the inspection — not the sale of the property. Do not order a point-of-sale lateral certificate for a straightforward resale here.
Why the claim spreads: The city appears on 'cities requiring sewer lateral certification' lists without the trigger being read closely, so a renovation-triggered rule gets treated as a sale-triggered one.

Los Gatos
Los Gatos requires a sewer lateral inspection at sale
NOT SUPPORTED. No sewer lateral inspection is required. West Valley Sanitation District maintains the lower portion when an approved property-line cleanout is installed.
Why the claim spreads: Same regional assumption as Palo Alto.

Palo Alto
Palo Alto requires a sewer lateral inspection at sale
NOT SUPPORTED. Palo Alto does not require sewer lateral inspections as part of the home-sale process. The owner is responsible for the upper lateral to the property line; the City maintains the lower lateral in the public right of way if it fails.
Why the claim spreads: Regional sewer-lateral ordinances are common enough in neighboring counties that agents assume Peninsula-wide coverage.

San Jose
San Jose requires a private sewer lateral inspection/certificate before a home can be sold
NOT SUPPORTED. The City of San Jose's own sanitary sewer pages describe maintenance responsibility and property-line cleanout requirements, not a point-of-sale certificate. The Santa Clara County Association of REALTORS local disclosure list for San Jose names the Apartment Rent Ordinance, Ellis Act and street tree requirements — no sewer lateral point-of-sale item. The Silicon Valley Association of REALTORS describes only the upper/lower lateral responsibility split for San Jose.
Why the claim spreads: Multiple plumbing-contractor websites describe a 'San Jose PSLP' program effective June 2022 exempting homes built within 15 years. Those are the exact terms of MORGAN HILL's ordinance (effective June 1, 2022, 15-year exemption). The claim appears to be Morgan Hill's ordinance mislabeled.

Saratoga
Saratoga requires a sewer lateral inspection at sale
NOT SUPPORTED for sewer laterals specifically. West Valley Sanitation District territory, same structure as Los Gatos. NOTE: Saratoga DOES have a separate septic/sewer-connection inspection for parcels beyond 200 feet of a public sewer, and an occupancy inspection for non-single-family transfers.
Why the claim spreads: Conflation of the septic inspection rule with a lateral inspection rule.
Solano County
Benicia
Benicia's property registration ordinance is a point-of-sale requirement that has to be cleared before escrow closes
NOT A SALE TRIGGER. The Solano Association of REALTORS county advisory describes these as vacant and foreclosed property registration programs: they "require the registration, maintenance, and security of vacant and foreclosed residential properties". The trigger is vacancy or foreclosure, not transfer. A seller of an occupied home is not caught by it; a bank selling an REO very likely is, and must register before it lists rather than before it closes. Rio Vista and Dixon had no registration programme as of 15 July 2016.
Why the claim spreads: It sits in the same county advisory as the genuine sale-triggered items, it is administered by Code Enforcement, and the phrase "registration ordinance" reads like a resale ordinance. It is also the item most likely to be genuinely relevant, because a large share of the transactions where anyone reads this advisory are REO.

Benicia
Benicia requires a resale inspection, occupancy inspection, energy audit, retrofit or point-of-sale sewer lateral test before a home sale closes
NONE FOUND. The City of Benicia's Building Safety Division describes permits for new construction, alterations, additions and owner-builder work, and inspections during construction. It names no resale inspection, occupancy certificate on transfer, energy audit, retrofit ordinance or point-of-sale lateral test. On laterals specifically the county REALTOR advisory states verbatim that "there are no mandatory inspections required for any of the cities in Solano County" — true when written in 2016, and still true for Benicia, though NO LONGER TRUE FOR VALLEJO, which adopted a point-of-sale lateral inspection ordinance in March 2025. The statewide seller obligations still apply.
Why the claim spreads: Benicia has the oldest housing stock in the county and visible sewer-infrastructure problems, which agents reasonably assume must be regulated at sale. Its vacant-property registration programme is also easily mistaken for one.
Fairfield
Fairfield's property registration ordinance is a point-of-sale requirement that has to be cleared before escrow closes

Unincorporated Solano County
Solano County requires a septic system inspection when a property is sold
NOT SUPPORTED for the sale trigger. Solano County Environmental Health's Onsite Sewage Disposal Program lists Sewage Disposal Permits, Liquid Waste Vehicle Permits, Operation & Maintenance Permits and Graywater Systems. None is described as triggered by sale, transfer, escrow or change of ownership. Note the contrast with San Mateo County, whose ordinance does require Operating Permit renewal at change of ownership — the answer is genuinely county-specific, so do not generalise either way.
Why the claim spreads: A septic inspection is near-universal as a buyer's due-diligence item and lenders often insist on one, which is easily mistaken for a government mandate. Some other California and out-of-state counties do impose one at transfer.

Unincorporated Solano County
Unincorporated Solano County imposes a local point-of-sale requirement — a county resale report, an energy or retrofit ordinance, or a defensible-space inspection of its own — that must be cleared before a home sale closes
NONE FOUND. Solano County Resource Management's Building & Safety ordinances page describes construction requirements only and names no sale trigger. Environmental Health's onsite-sewage program lists Sewage Disposal, Site Evaluation, Liquid Waste Vehicle and Operation & Maintenance permits plus graywater approvals, none of them triggered by transfer. On fire, the county's own page states that the State Fire Marshal released updated Local Responsibility Area Fire Hazard Severity Zone maps for Solano County on February 24, 2025 and that "Solano County will enforce requirements for building construction in the LRA in unincorporated areas of the County beginning July 2025" — building construction, not point of sale. Statewide AB 38 still applies to parcels in a High or Very High zone, and the 2025 remap changes which parcels those are. No county-level resale report, energy ordinance or retrofit ordinance was found.
Why the claim spreads: Solano is the only one of the nine counties where the unincorporated area is mostly agricultural, so agents assume it must be regulated like the rural parts of Marin or Sonoma, where fire districts genuinely do run resale inspections. The February 2025 fire-zone remap is also easy to misread as a new sale requirement when it is a building-code one.
Vacaville
Vacaville's property registration ordinance is a point-of-sale requirement that has to be cleared before escrow closes

Sonoma County
Healdsburg
Healdsburg requires a sewer lateral inspection or certificate at point of sale
NOT SUPPORTED BY THE ORDINANCE. Healdsburg Ordinance No. 1127 enumerates six triggers for a mandatory CCTV inspection and certificate of private sewer lateral compliance: (A) a qualifying sewer lateral service call; (B) issuance of a building permit valued at $25,000 or more where no inspection has occurred in the previous 20 years; (C) a sanitary sewer overflow caused by the lateral; (D) a change of use of the structure; (E) replacement or repair of any part of the lateral; and (F) significant repair or replacement of the main sewer line. Sale or transfer of the property is NOT among them. The only sale-related provision found concerns pre-existing SHARED lateral connections, which must be separated when a parcel is sold.
Why the claim spreads: An industry sewer-lateral requirements matrix lists Healdsburg as requiring certification at point of sale. That appears to be wrong, or to reflect a practice rather than the ordinance. Because a $25,000 building permit is a trigger, a seller who did recent work may still owe an inspection — which can look like a point-of-sale rule from the outside.
Unincorporated Sonoma County
Sonoma County sanitation districts require a point-of-sale sewer lateral inspection for laterals over 30 years old
NOT REQUIRED AT POINT OF SALE. Sonoma Water states that the proposed Private Sewer Lateral Ordinance for its sanitation zones and districts will NOT require any point-of-sale sewer lateral inspections or repairs. The 30-year figure is real but belongs to a different mechanism: the ordinance reaches properties 30 years or older, and the District itself conducts video inspections and smoke testing — offered FREE, and proceeding automatically unless the owner declines in writing. Where significant defects are found, the owner has one year from the report date to repair.
Why the claim spreads: An aggregated disclosure guide described this as a point-of-sale requirement for lines over 30 years old. The 30-year threshold and the inspection obligation are both genuine, so the rule reads like a point-of-sale trigger unless you check what actually sets it off — District-initiated inspection, not a sale.
