What Santa Monica home values did
Santa Monica values peaked in June 2022, then slid 8.2% by January 2026, the month that matters for the 2026 assessment. Across Los Angeles County, the typical value was 1.6% below its own peak at the same point, so Santa Monica saw a deeper drop than the county as a whole.
Values have held roughly steady since January, through August 2026, so the picture for the 2027 roll looks similar so far.

Which Santa Monica owners may be over-assessed
Under Prop 13, your assessment starts at your purchase price and can rise up to 2% a year. Under Prop 8, it must drop to market value whenever market value as of January 1 is lower. The table compares a typical purchase in each year with the January 2026 typical value of $1,678,000.
| Bought in | Typical price that year | Rough 2026 assessment | vs. January 2026 value |
|---|---|---|---|
| 2021 | $1,658,000 | $1,831,000 | Possibly over-assessed by about $153,000 |
| 2022 | $1,803,000 | $1,952,000 | Possibly over-assessed by about $274,000 |
| 2023 | $1,710,000 | $1,815,000 | Possibly over-assessed by about $138,000 |
| 2024 | $1,693,000 | $1,762,000 | Possibly over-assessed by about $84,000 |
| 2025 | $1,665,000 | $1,699,000 | Close to market |
The buyers most likely to be over-assessed are those who bought in 2021, 2022, 2023 and 2024. A typical 2022 purchase would carry a 2026 assessment of roughly $1,952,000 after the 2% annual increases, about $274,000 more than the January 2026 typical value. At California's 1% base tax rate, that's on the order of $2,740 a year before local voter-approved add-ons.
This is an illustration built on citywide typical values, not an estimate of your home. Your assessment notice shows your actual assessed value, and some assessors lower values on their own in a falling market, so check it first. If you do appeal, your evidence has to show your home's market value.
Los Angeles County deadlines
- 2026 regular filing period: July 2 through November 30, 2026. If you think the 2026 value is too high, this is the window.
- Informal review: the Los Angeles County Assessor may review a decline-in-value request informally. File the formal application anyway if the deadline is close; an informal review doesn't extend it.
- Supplemental or escape assessments: these have their own deadline, generally 60 days from the notice date. Check the notice.

Building a Santa Monica case
A citywide index shows the trend. Your appeal needs your house. Look for sales of similar homes in Santa Monica that closed near January 1, 2026. The BOE treats comparable sales as the strongest evidence for a home, and the appeals board can't consider sales more than 90 days after the valuation date. Match living area, age, condition, lot and location as closely as you can, and write down every difference you can't adjust for.
Santa Monica sits in the Los Angeles-Long Beach-Anaheim metro, but neighborhood differences matter more than metro trends. A sale across town can be a weaker comparison than one a few streets away.
A Vulorean report pulls comparable sales and a January 1 value opinion into one document you can file with. Eligible self-file reports are free during launch, with no payment card required. Review every comparison before you use it; you know your home's condition better than any dataset.
