Date of Death Appraisals in Orange County: Commercial Property in Estates and Trusts

Orange County families have held commercial real estate for decades: an older apartment building in Santa Ana or Anaheim, a small industrial building in Fullerton or Orange, a neighborhood center in Garden Grove, a mixed-use building near the beach in Newport or Laguna. When the owner dies, the first number the trustee, the executor and the CPA all need is what each property was worth on the date of death. Our statewide guide to date-of-death appraisals covers the basics. This page covers what is different when the property is in Orange County.

When does an Orange County estate or trust need a date-of-death appraisal?

Most of the time when the property is commercial or income-producing. Common reasons:

• Stepped-up basis. Under Internal Revenue Code Section 1014(a), property acquired from a decedent generally takes a basis equal to its fair market value at the date of death. When an heir or the trust later sells, the CPA needs a supported number for that basis.
• Estate tax returns. For larger estates, the value of each property goes on the return. Under Section 2032, the executor can elect to value the estate as of six months after death instead (or as of the date of an earlier sale or distribution), but only if the election lowers both the gross estate and the tax. That can mean two values for the same property.
• Trust administration. A successor trustee dividing or selling property needs values to treat beneficiaries fairly and to report to them. See trust administration appraisals.
• Equalizing shares. One child keeps the apartment building, another takes the industrial building and a third takes cash. A value for every property, on the same date, is what makes that split fair.
• Disputes. Heirs, trustees and creditors sometimes disagree about value. An independent, well-supported report keeps the conversation on the evidence.
• Property tax. Prop 19 reassessment and any appeal of the new value turn on what the property was worth on the date of death (see below).

How does probate work for real estate in Orange County?

The Orange County Superior Court’s probate self-help page says probate court is at the Costa Mesa Justice Complex, 3390 Harbor Blvd., Costa Mesa, and that the Probate Clerk’s Office is on the first floor of that courthouse. Probate cases from every part of the county are heard there.

In a formal probate, the personal representative delivers the inventory to the probate referee designated by the court, and under Probate Code Section 8902 the referee appraises the property the personal representative does not. That is the court’s inventory value. It is not the same thing as a private narrative appraisal, and the two serve different purposes. We do not act as a probate referee. We provide independent appraisals to trustees, executors, heirs and their attorneys and CPAs.

Many Orange County estates never see a courtroom because the property was held in a living trust. Then there is no referee, and the successor trustee needs values on their own. If a trust dispute or a sale does end up in court, a report prepared as of the date of death is already on file.

What does the community property rule mean for basis?

California is a community property state, and that matters here. Section 1014(b)(6) treats the surviving spouse’s one-half share of community property as acquired from the decedent too, as long as at least half of the whole community interest was includible in the decedent’s gross estate. In plain terms, when the property was community property, the date-of-death value can set the new basis for the whole property, not just the decedent’s half. Many Orange County couples bought commercial property decades ago at a fraction of today’s prices, so that basis can make a large difference when the property is sold.

General information, not tax advice. Talk to your CPA about how Section 1014 applies to your estate.

Does Prop 19 trigger a reassessment of inherited Orange County commercial property?

Usually, yes. The State Board of Equalization explains that for transfers on or after February 16, 2021, Prop 19 limits the parent-child exclusion to a family home or family farm, with a value limit, and eliminates the exclusion for other real property. So when a parent dies and a child inherits an apartment building, a retail center or an industrial building, the Orange County Assessor will generally set a new base year value as of the date of death.

The paperwork has a clock. Under Revenue and Taxation Code Section 480, when a change in ownership happens because of a death, the change in ownership statement (BOE-502-D) is due within 150 days after the date of death, or, if the estate is probated, when the inventory and appraisal is filed. If the assessor’s new value looks too high, a supported date-of-death appraisal is the evidence for an appeal. For 2026, the State Board of Equalization lists November 30, 2026 as the end of the regular assessment appeal filing period in Orange County; supplemental and escape assessments have their own deadlines. See property tax appeal appraisals.

What Orange County issues change a value as of the date of death?

A date-of-death appraisal has to read the property as it was on that date. In Orange County, these come up again and again:

• Santa Ana rent stabilization. The City of Santa Ana’s Rent Stabilization and Just Cause Eviction Ordinance limits rent increases to the lower of 3 percent a year or 80 percent of the change in CPI for covered units, and the city says the cap applies to residential structures built on or before February 1, 1995, and to mobilehome parks established before 1990. The allowed increase resets each September: the city lists 3.00 percent for September 2024 through August 2025, 2.42 percent for the following year and 2.87 percent for September 2026 through August 2027. For an older Santa Ana apartment building, the rents in place and the cap in effect on the date of death shape the income and the value. Most other apartments in the county fall under the state cap in Civil Code Section 1947.12, which has its own exemptions.
• The coast. Property from Seal Beach to San Clemente can sit inside the California Coastal Zone, where development is reviewed under the Coastal Act and each city’s local coastal program. What an owner could build, rebuild or convert on the date of death is part of highest and best use, and coastal sales have to be read with those limits in mind.
• Wildfire at the canyon edge. The Airport Fire started September 9, 2024 near Trabuco Canyon, burned 23,526 acres in Orange and Riverside counties and destroyed 160 structures. For property near the wildland edge, the date of death decides whether the appraisal reads a pre-fire or post-fire property and market. See casualty loss appraisals for before-and-after values.
• Leases and occupancy on the date. A building that was half vacant on the date of death, or that had a below-market lease with years left, is valued that way, even if it is full today.
• Many markets in one county. Orange County has 34 incorporated cities, and an Anaheim industrial building, an Irvine office building and a Laguna Beach storefront do not trade the same way. Comparable sales have to come from the right submarket and the right time.

Can the appraisal be done years after the date of death?

Yes, and it often is. Estates and trusts can take a long time to settle, and sometimes nobody orders an appraisal until a property is about to be sold or a dispute starts. A retrospective appraisal uses the sales, leases and market conditions that were known or knowable as of the date of death. What helps most is anything that shows the property as it was then: photos, the rent roll and leases in place, operating statements for the year around the date, rent increase notices, and records of repairs or permits.

What should you send the appraiser?

• The exact date of death and, if there is one, the probate case number
• The purpose: basis, estate tax return, trust administration, division among heirs, a Prop 19 matter or a dispute
• A list of every property with address, APN and property type, in Orange County and anywhere else in California
• Rent rolls, leases, rent increase notices and operating statements from around the date of death
• Photos and repair or permit records from that time
• Any prior appraisals, purchase contracts, offers or assessor notices
• The attorney or CPA on the estate, and who else will rely on the report

Your appraiser will confirm the exact list on the first call.
