SB288 amends California’s change‑in‑ownership rules to allow certain transfers of principal residences and family farms between parents and children and between grandparents and grandchildren (when the child‑generation parents are deceased) to avoid reassessment. It sets a formula that excludes up to $1,000,000 above the prior taxable value from being newly taxed, requires the transferee to occupy the home and claim a homeowners’ or disabled veterans’ exemption within specified windows, and treats transfers through trusts and probate as eligible when claimed properly.
The bill also prescribes administrative mechanics: confidentiality for exclusion claims, a statewide claim form from the State Board of Equalization after consultation with county assessors, a wildfire‑related timing exception for impacted properties, an assessor notice and late filing process with a one‑time processing fee cap, and emergency regulations to implement the scheme. Practically, SB288 affects estate planning, farm succession, assessor workloads, and local property tax revenues by limiting reassessments on a defined slice of intergenerational transfers.
At a Glance
What It Does
SB288 creates a change‑in‑ownership exclusion for transfers (including trust and probate transfers) of a transferor’s principal residence and for family farm parcels when transferred between parents/children or grandparents/grandchildren if the intermediate parents are deceased. The bill preserves the transferor’s base year value except that the exclusion only shelters up to $1,000,000 above the prior taxable value; any excess increases taxable value.
Who It Affects
The primary targets are families transferring homes or working farms across generations, county assessors and their offices, probate and title professionals handling intergenerational transfers, and county governments that may collect a processing fee for late claims. It also implicates planners advising on property tax consequences of estate strategies.
Why It Matters
SB288 changes the economics of keeping family homes and farms in the family by reducing abrupt tax spikes on eligible transferees, while carving out a dollar cap that preserves some reassessment revenue. It creates new filing, notice, and administrative requirements that counties must operationalize and that practitioners must account for when advising clients on transfers, trusts, and probate.

What This Bill Actually Does
SB288 establishes a narrowly drawn exclusion from reassessment for two types of intergenerational transfers: principal residences and family farms. For grandparent‑to‑grandchild transfers the exclusion is available only when the child generation (the parents of the grandchild) are deceased at the time of transfer.
Transfers made through inter vivos or testamentary trusts and transfers that result from probate orders are explicitly covered, but the transferee must turn the property into their principal residence and claim either the homeowners’ or disabled veterans’ exemption within one year.
The bill determines the new taxable value by adding the prior taxable value (adjusted as allowed elsewhere in law) to a second component calculated against fair market value at transfer. If fair market value is less than the prior taxable value plus $1,000,000, the second component is zero and the transferee effectively keeps the prior taxable base.
If fair market value exceeds that sum, the transferee’s new taxable value increases only by the amount above the prior taxable value plus $1,000,000. The statute treats each legal parcel of a family farm separately and excludes parcels that contain a family home from the farm parcel rule so they can instead qualify under the residence rule.Procedurally, SB288 requires claim forms prescribed by the State Board of Equalization after consulting the California Assessors’ Association and makes most claims confidential while permitting inspection by specified parties (transferor, transferee, their spouses, legal representatives, trustees, and estate executors).
Claim filing generally must occur within three years of the transfer (with earlier cutoffs if the property is later sold or the transferee stops occupying the residence), but there are special timing rules tied to supplemental or escape assessments and a carve‑out for properties reassessed because of designated 2025 wildfire disasters; that carve‑out extends certain filing windows for claims filed before January 1, 2031.If an assessor notifies a transferee that they may be eligible for the exclusion, the transferee must file a certified claim quickly or face reassessment activity; after a second notice the county may charge a one‑time processing fee (up to actual costs or $175) for late certified claims. The bill authorizes emergency regulations to get forms and procedures into place rapidly and makes technical enrollment rules for when an exclusion ends and the base year value must be re‑established.
The Five Things You Need to Know
The exclusion applies retroactively to transfers occurring on or after February 16, 2021.
To qualify, a transferee must make the property their principal residence within one year and file for the homeowners’ or disabled veterans’ exemption within one year of the transfer (or within one year of a probate order’s effective date).
The exclusion shelters up to $1,000,000 above the prior taxable value: if fair market value at transfer exceeds prior taxable value plus $1,000,000, the taxable value increases by that excess amount; otherwise there is no increase.
Claim filing is generally due within three years of the transfer (or earlier if the property is sold or the transferee stops occupying); special wildfire reassessment circumstances create an alternative three‑year window and other timing relief that applies only to claims filed before Jan 1, 2031.
If a transferee ignores assessor notice and files late after a second notice, the county may impose a one‑time processing fee up to actual costs or $175, reimbursable if the claim is later found ineligible.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Principal residence exclusion for parent‑child and eligible grandparent‑grandchild transfers
This subsection defines when a principal residence change in ownership is not a reassessment trigger: transfers between parents and children and transfers between grandparents and grandchildren provided the intermediary parents are deceased. It conditions the exclusion on the property becoming the transferee’s principal residence within one year and on timely filing for homeowners’ or disabled veterans’ exemption. It also explains when the exclusion is removed and how the base year value is enrolled if the transferee later becomes ineligible.
Family farm exclusion and parcel‑by‑parcel treatment
SB288 extends a similar exclusion to family farms and treats each legal parcel of a farm as a separate family farm for purposes of the exclusion, except that parcels containing a family home can qualify under the residence rules instead. This parcelized approach matters for operations composed of multiple tax parcels and limits the possibility of applying one large exclusion across disparate parcels.
Claim requirement and confidentiality
The statute makes the exclusions available only upon filing a claim and makes those claims nonpublic while explicitly allowing access to a short list of interested parties (transferor/transferee, spouses, trustees, legal representatives, executors). That confidentiality lowers privacy concerns for families but restricts public oversight and preserves the assessor’s ability to audit eligibility through the listed parties.
Valuation formula, definitions, and scope
Section (d) sets the two‑part taxable value calculation: the prior taxable value (with ordinary annual adjustments) plus either zero or the amount by which fair market value exceeds prior taxable value plus $1,000,000. Subdivision (e) supplies working definitions — children (broadly defined to include step, in‑law, adopted, and some foster relationships), family farm, family home, full cash value, and that 'transfer' includes trust and probate transfers. Those definitions govern eligibility disputes and how parcel types are categorized.
Claim filing windows and wildfire exception
This section prescribes the main deadline framework: generally a claim must be filed within three years of transfer or before the property is sold or the transferee stops occupying the residence, with an alternate six‑month rule tied to mailing of a supplemental/escape assessment. It adds a targeted exception for properties reassessed after specified 2025 wildfires — under strict conditions the claim window is extended and certain exemption filings are treated as timely — but that wildfire relief only applies to claims filed before January 1, 2031.
Assessor notice, certified claim requirement, and late‑filing fee
Assessors who identify potential eligibility must notify transferees; recipients must file a certified claim within 45 days or face a second notice which starts a 60‑day deadline before reassessment begins. If the transferee files after that second 60‑day period, the county may charge a one‑time processing fee (set against actual costs and capped at $175) subject to board of supervisors authorization and reimbursement if the claim is ineligible.
Regulatory authority and emergency procedures
The State Board of Equalization must produce claim forms and instructions after consulting the California Assessors’ Association and is authorized to adopt emergency regulations to implement the section quickly. The bill directs that these emergency regulations be treated as necessary for the public welfare for purposes of the Administrative Procedure Act, facilitating rapid operational roll‑out.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Grandchildren and children who inherit or receive family homes when parents are deceased — they avoid full reassessment shock and can retain the transferor’s base year benefit up to the $1,000,000 cushion.
- Family farm operators staying in the family — parcelized treatment lets smaller farm parcels avoid immediate large tax hikes, supporting agricultural continuity and succession.
- Estate beneficiaries in probate where the transferor’s home or farm passes under court order — the bill explicitly covers probate transfers and deems the one‑year occupancy/filing clock to run from the probate order’s effective date, simplifying conversions in many estates.
- Practices and advisors that counsel on succession planning — reduced tax exposure on qualifying transfers creates clearer, more predictable advice for families considering intra‑family transfers.
Who Bears the Cost
- County assessors — they must implement new claim forms and confidentiality rules, process possibly retroactive claims, handle wildfire‑related timing exceptions, and administer notice and fee procedures, increasing workload and systems complexity.
- Local governments and school districts — the $1,000,000 cap limits immediate reassessment revenue on eligible transfers and can reduce short‑term property tax growth relative to full reassessment scenarios.
- Title companies and probate attorneys — they must collect and supply the documentation necessary to support eligibility (proof of parental death, trust instruments, residency claims) and may face more client work to preserve exclusion rights.
- Transferees of higher‑value properties — purchasers whose transactions exceed the prior taxable value plus $1,000,000 will still face partial reassessment and must navigate filing windows or risk paying fees if notices are missed.
Key Issues
The Core Tension
The bill balances two legitimate goals — preventing disruptive tax spikes that force sales of family homes and farms, and preserving the integrity and revenue base of local property tax systems — but solving one problem (intergenerational continuity) forces trade‑offs: added administrative complexity, retroactive claim processing, and a $1,000,000 cap that limits relief for high‑value properties while shifting some fiscal costs to local governments.
SB288 trades administrative complexity for targeted tax relief. The retroactive effective date (Feb 16, 2021) and explicit coverage of trust and probate transfers mean assessors will confront both backlogged claims and disputes about when the occupancy and exemption clocks begin.
Demonstrating eligibility — showing that the child generation is deceased for grandchild transfers, proving the land parcel qualifies as a family farm, or isolating the 'reasonable size' of land underlying a family home — invites fact‑intensive adjudication that will increase appeals and workload.
The $1,000,000 cushion is an explicit compromise: it limits taxpayer relief compared with a full carryover but preserves some reassessment for very valuable properties. That dollar cap may blunt the policy’s intended support for farm continuity in regions with rapidly rising land values, producing an uneven benefit for smaller versus larger farms.
The wildfire timing exception improves fairness for disaster victims but adds a narrow, date‑bound complexity that will require assessors to track disaster proclamations, reassessment reasons, and probate timing to determine whether the extended windows apply.
