What is the difference between a seller disclosure, an inspection report and a transfer certificate? A disclosure communicates known facts; an inspection reports on a defined scope of property conditions; a certificate documents compliance with a particular program. One does not replace the others.
For many covered one-to-four-unit residential sales, the baseline includes the California Transfer Disclosure Statement and Natural Hazard Disclosure, known material facts and prior reports, the federal lead disclosure for most pre-1978 housing, and HOA resale documents when applicable. Exemptions and additional notices remain property- and transfer-specific.
There is no single “Bay Area disclosure package” and no statewide rule requiring every seller to order a general home inspection before listing. Required information and local obligations depend on the address, property type and transfer.
This is educational information, not legal, property-condition or code-compliance advice. Current duties, exemptions and condition conclusions must be confirmed for the actual property and transfer.
Four terms with different meanings
| Term | What it means | Important limit |
|---|---|---|
| Disclosure | Information about the property and known facts provided to a buyer | It is not a warranty or a substitute for the seller's other disclosure duties. |
| Inspection | Observation or testing within a professional's defined scope | Access limits and exclusions can leave other conditions unexamined. |
| Report | A written record of findings or government records | A records report such as San Francisco's 3R is not a physical inspection. |
| Compliance certificate | Documentation of a specific program's requirements or formally approved status | It does not certify the entire property. |
California and federal disclosure terms
What is the Transfer Disclosure Statement?
California's statutory transfer-disclosure rules generally apply to transfers of one-to-four-unit residential property, including many condominium and planned-development resales, subject to stated exemptions. The Real Estate Transfer Disclosure Statement, commonly called the TDS, asks the seller to identify property features and disclose known defects, malfunctions and other conditions.
The TDS is not an inspection and is not a warranty. The seller answers from actual knowledge; a real estate licensee has a separate statutory role that includes a reasonably competent and diligent visual inspection in covered one-to-four-unit transactions. Neither role should be treated as a substitute for an engineer, contractor, environmental professional or other specialist.
Complete the seller's disclosures carefully rather than guessing, diagnosing or using an inspection report as a shortcut. If a question is unclear, identify the underlying facts and ask the appropriate real estate or legal professional how they should be presented.
California requires the TDS to be delivered as soon as practicable before transfer of title. If a disclosure required by the TDS article—or a material amendment to one—is delivered after an offer is executed, Civil Code Section 1102.3 gives the buyer a statutory termination period: three days after personal delivery or five days after delivery by mail or agreed electronic record. Early delivery is therefore more than an organizational preference; timing can affect the buyer's rights and the transaction.
Some transfers—such as specified court-ordered, foreclosure, fiduciary, co-owner, family and governmental transfers—may be exempt from the TDS article. The exemption language is specific, and an exemption from this form does not automatically eliminate every other disclosure duty, federal rule or local transfer requirement. Trust, probate, conservatorship and court-connected sellers should have the applicable exemption and remaining duties confirmed rather than inferred.
What is the Natural Hazard Disclosure?
The Natural Hazard Disclosure Statement, or NHD, addresses whether the property lies within mapped hazard areas. The current statutory statement includes:
- FEMA special flood hazard areas;
- potential dam-failure inundation areas;
- high or very high fire hazard severity zones, with the current form distinguishing high and very high zones in state responsibility areas and very high zones in local responsibility areas;
- designated wildland fire areas;
- earthquake fault zones; and
- seismic hazard zones for landslide or liquefaction.
A third-party natural-hazard report is commonly used to support this disclosure, but the NHD is still only a map-based disclosure. It does not predict whether a specific home will flood, slide, burn or experience earthquake damage, and it does not determine insurance availability or cost. A seller or agent's other known material information is not erased by the report.
What is a known material fact?
California's statutory forms are not an exhaustive list of everything that can matter. The current Civil Code preserves duties intended to prevent fraud, misrepresentation or deceit and expressly recognizes material facts affecting value or desirability, including physical condition and previously received inspection reports.
Material information can include physical conditions, prior inspection reports, water intrusion, repair history, permit questions, insurance losses, shared maintenance arrangements, occupant agreements and notices from public agencies. Missing records are not evidence that no issue exists. A seller's observation and a specialist's technical conclusion are different kinds of information.
An “as-is” sale does not waive the TDS article where it applies or authorize concealment of known material facts. It may affect who agrees to perform or pay for repairs, but other disclosure duties still must be analyzed under the law that governs the property and transaction.
What is the federal lead-based-paint disclosure?
Federal law applies to most housing built before 1978, with defined exemptions. Before a buyer is obligated under a contract for covered housing, the seller must provide the approved lead-hazard pamphlet, disclose known lead-based paint or lead hazards, provide available records and reports, and include the required warning and acknowledgment language in the contract process.
The buyer must also receive a 10-day opportunity to conduct a lead inspection or risk assessment unless the parties agree in writing to a different period or the buyer waives the opportunity in writing. The federal disclosure rule does not generally require the seller to conduct or pay for a lead inspection. If the seller already has lead-related records or commissions testing, however, the disclosure file should include the resulting information as required.
Required disclosure of known lead information is distinct from an optional seller-commissioned lead inspection.
What are HOA resale documents?
For a California common-interest development, the owner must provide the documents listed in Civil Code Section 4525 as soon as practicable before transfer of title or execution of a real property sales contract. The package can include governing documents, current financial and policy disclosures, assessments and unpaid charges, unresolved violation notices, approved assessment changes, rental restrictions and recent board minutes when requested.
Effective January 1, 2026, the Section 4525 statutory list also includes a copy of the report issued from the most recent exterior-elevated-element inspection conducted under Civil Code Section 5551. Section 5551 has its own applicability and inspection rules, so confirm what report the association actually has rather than assuming every HOA must have the same report. An association report is not a substitute for an inspection of the seller's unit, and a unit inspection does not reveal the association's reserves, insurance, litigation or planned capital work.
HOA governing documents can assign maintenance responsibility to the association or an individual owner. That distinction can affect which party is responsible under a local sidewalk or sewer-lateral program.
What other notices can apply?
Other California disclosures may apply because of the property's location, age, recent ownership history, condition, financing, occupancy or use. Examples can include wildfire defensible-space documentation in covered high and very high fire hazard severity zones; notices about water-conserving plumbing fixtures, special taxes or specified nearby uses; specified contractor-work and permit information when a single-family seller accepts an offer within 18 months after acquiring title; and, beginning January 1, 2026, a seller's duty to disclose in writing actual knowledge of residue from smoking tobacco or nicotine products, or a history of occupants smoking those products on the property. For this rule, smoking expressly includes using an electronic cigarette or vape device to inhale an aerosol. The duty applies to single-family residential property subject to the TDS article.
Tenant-occupied property, solar or other financed equipment, affordable-housing restrictions, seismic programs, manufactured housing, new subdivisions, estates and unusual title structures can add their own documents and professional questions. This guide is not a form inventory. Applicable duties require a property-specific determination under current law; last year's documents may not cover a current transfer.
What do Bay Area transfer-compliance programs cover?
Local requirements can apply in addition to the statewide and federal disclosures, and more than one can apply to the same sale. The comparison below covers representative programs in Westin's core Bay Area service area; it is not a complete list of every city, utility district, property type or exemption.
Confirm the exact parcel, jurisdiction, utility service area, building type, HOA responsibility and transfer type directly with the administering agency. Rules, fees, forms, processing systems and extensions can change.
| Place or program | When it may apply | Program requirement and timing | What the resulting document does—and does not—establish |
|---|---|---|---|
| Oakland sidewalk certification | Oakland title transfers, with enumerated exceptions; certain major renovations are a separate trigger | Check the City's records for a valid certificate. If none exists, arrange the required inspection and any repair, then obtain a standard, exemption or—when work cannot be finished before transfer—provisional certificate through OakDOT. The City states that a final compliance certificate is valid for five years and a provisional certificate must be issued before transfer. | Addresses the abutting sidewalk under Oakland's program. It does not inspect the house, private sewer lateral or every HOA walkway. |
| EBMUD Regional Private Sewer Lateral Program | Title transfers for residential, commercial and industrial properties in Alameda, Albany, Emeryville, Oakland, Piedmont, El Cerrito, Kensington and the Richmond Annex, subject to program rules and exemptions | Search the certificate status and determine whether the owner or HOA is responsible. If triggered, obtain an EBMUD Compliance Certificate after the required verification test, or determine whether a 180-day Time Extension Certificate is available before transfer. | Confirms the tested private sewer lateral met the program's leak-free standard. It is not a general plumbing inspection, and Berkeley uses its own sewer-lateral program. |
| Berkeley private sewer lateral | Transfers or sales of Berkeley buildings, including condominiums and developments with shared laterals, subject to stated exceptions | Check for a current City Sewer Lateral Certificate. Without qualifying evidence of prior compliant work, a contractor may need to test, repair or replace the lateral and obtain City verification. Berkeley may approve a six-month extension through its prescribed process in some cases. | Confirms compliance with Berkeley's private-sewer-lateral standard. It does not establish the condition of all plumbing or satisfy Berkeley's separate BESO requirements. |
| Berkeley BESO—single-family homes and duplexes | Sales beginning January 1, 2026, subject to building and transaction exemptions | Obtain a separate Home Energy Score for each unit before listing, place the score in the MLS Property Notes as directed by the City, and include the report and assessment confirmation in disclosure and transfer documents. Before the sale is finalized, follow one City path: obtain a compliance certificate for qualifying upgrades, obtain an approved exemption or complete the formal buyer-deferral and deposit steps at closing. The City's July 2026 guide describes seller-completed upgrades as a pre-listing path. | Documents the BESO assessment and the selected compliance path. It is not a whole-home condition inspection. Attached condominiums, ADUs and other property types have specific treatment that should be confirmed with BESO staff. |
| Berkeley BESO—three- and four-unit residential buildings | Through 2027, the City's current multifamily/commercial time-of-sale compliance path applies; the small-residential resilience standard is scheduled to begin for these properties in January 2028 | Check BESO status before listing and complete an energy assessment, document a qualifying upgrade or exemption, or obtain the formal buyer deferral under the current program. Confirm the rule for mixed-use and larger buildings by size and use. | Addresses energy-assessment or BESO status only. It does not replace physical-condition, HOA, sewer or other disclosures. |
| San Francisco 3R report | Sale or exchange of a residential building, except the first sale or exchange of a newly constructed residential building within one year of its Certificate of Final Completion | Order the Report of Residential Building Record early and deliver it to the buyer before the sale or exchange is completed. Confirm whether separate reports are needed for multiple buildings or individual condominium or cooperative interests. | Reports authorized use and building-permit information found in City records. DBI states that it is not a physical examination, omits plumbing and electrical permit history, and does not represent that the property complies with law. |
| San Francisco residential energy and water conservation | Covered residential title transfers by sale or exchange, subject to exemptions, prior recorded compliance and the code's prescribed postponement or escrow paths | Search for recorded certificates and confirm current applicability with DBI. Where required, obtain qualified energy and water inspections, complete applicable measures and record compliance, or use the formal process that allows responsibility to pass to the buyer with an escrow arrangement. | Confirms only the measures required by the Residential Energy Conservation Ordinance and Residential Water Conservation Ordinance. It is not a general home inspection or a substitute for the 3R report. |
What do optional inspection reports cover?
A general pre-listing inspection is different from a legally required local test or certificate. Optional inspections have different scopes, costs and access limitations. Selecting them for a particular property is part of the private professional conversation.
| Inspection or review | Subject | Important limit |
|---|---|---|
| General home inspection | Visible, accessible building systems and components within the agreement | Usually visual and noninvasive; not every component or concealed condition is included. |
| Structural pest inspection | Wood-destroying organisms and related conditions within the report's scope | It is not a structural engineering opinion or a guarantee against future damage. |
| Roof inspection | Roof coverings, visible conditions and the inspector's stated scope | Concealed conditions and future service life may remain uncertain. |
| Sewer camera inspection | Visible conditions along the accessible pipe | A camera report is not automatically the verification test or certificate required by a utility program. |
| Specialist evaluation | A specific structural, drainage, electrical, environmental or other question | Conclusions belong to the qualified professional and the scope of that engagement. |
A report may identify a condition without establishing its full cause, repair cost or legal significance. Cosmetic work must never conceal a known condition, and a repair does not necessarily remove the duty to disclose the condition's material history.
Frequently asked questions
Is a Bay Area seller required to get a general home inspection before listing?
Not as a universal statewide rule. California requires disclosures in many residential transfers, and some local programs require a particular inspection, test, report or certificate. A general pre-listing home inspection is a separate service unless the property's facts, contract or another rule make it necessary.
Is an inspection report the same as a disclosure?
No. The report communicates findings within the inspector's scope; the seller must still complete applicable disclosures and disclose other known material facts. The report should be included or referenced when required, but it does not speak for everything the seller knows.
Does the TDS replace the buyer's inspections?
No. The statutory TDS itself explains that it is not a warranty or a substitute for inspections. A buyer should investigate the property under the purchase agreement and with the appropriate professionals.
Does selling “as is” eliminate seller disclosures?
No. “As is” can affect the repair bargain, but it does not waive the TDS article where it applies or authorize concealment of known material facts. Other disclosure duties depend on the governing law and transaction facts, which should be reviewed with the transaction professionals.
Must a seller repair everything disclosed or found in an inspection?
Not automatically. Local compliance, safety, lender, insurance or contractual requirements can require action. An inspection finding by itself does not determine who must perform or pay for repairs. Property-specific conclusions belong with the responsible agency and qualified professionals.
Can the buyer take responsibility for local compliance after closing?
Only when the governing program provides an approved path and its steps are followed. Oakland, EBMUD, Berkeley and San Francisco each use different certificates, agreements, deposits, deadlines and eligibility rules. A private agreement between buyer and seller does not by itself satisfy the agency.
Who pays for a sidewalk, sewer lateral or energy upgrade?
The ordinance may place the compliance obligation on an owner or property while allowing the parties to negotiate cost or future work through a prescribed process. The purchase contract, escrow instructions, HOA documents and agency rules need to align. Confirm both legal responsibility and the negotiated economic allocation.
Are probate, trust or family transfers exempt from every disclosure?
No universal exemption applies to everything. A transfer may be exempt from one California disclosure article while remaining subject to other state or federal duties, known-material-fact principles or local programs. Confirm the precise transfer and the transferor's role with a California real estate attorney and the local agency.
Does a new inspection report affect disclosure duties?
It can. A seller should expect the report and material findings to become part of the factual record. An inspection does not replace the seller's own disclosure duties.
Professional boundary
This guide is educational real estate decision guidance, not legal, property-condition, engineering, environmental, construction, insurance or code-compliance advice. Disclosure obligations and exemptions depend on the property, parties, transfer and current law. Westin can discuss your property's circumstances privately and coordinate the appropriate professional conversations. A qualified California real estate attorney should confirm legal duties and exemptions; the administering city or utility should confirm local compliance; and appropriately licensed inspectors, engineers, contractors and environmental professionals should make condition conclusions within their disciplines.
