Can My Manhattan Beach Property Taxes Jump More Than 2% in One Year Under Prop 8?

Published July 15, 2026

Yes. Once your assessment was lowered under Prop 8, it can snap back above 2% in a single year.

Yes. Once your Manhattan Beach property's assessed value has been temporarily lowered under Proposition 8's decline-in-value rule, the county assessor can raise it back by more than the usual 2 percent cap in a single year, and even all the way back to your full Proposition 13 factored base year value in one jump, as market values recover. That restoration is not limited by the 2 percent rule at all.

Two different caps, and owners mix them up

California property tax has two separate ceilings that people often blend into one rule. Proposition 13, from 1978, caps the annual increase in your assessed value at 2 percent as long as you own the property and made no changes to it, per California Constitution Article XIIIA, section 2. Proposition 8, passed later that same year, is a completely different mechanism. It requires the assessor to temporarily lower your assessed value, below your Prop 13 factored base year value, whenever the market value of your property drops below that base. Once your property is sitting in "decline in value" status, the 2 percent Prop 13 cap no longer governs it. Instead, the assessor is required to review the market value every January 1 lien date and adjust the assessment up or down to track the market, codified in Revenue and Taxation Code section 51(a)(2).

Why a jump can exceed 2 percent

Here is the mechanic owners in Manhattan Beach and the South Bay run into most: because a Prop 8 reduced assessment is not a Prop 13 base year value, it is not subject to the 2 percent annual growth ceiling. So if the local market recovers sharply after a downturn, the assessor can restore your assessed value in a single year all the way up to your original Prop 13 factored base year value (adjusted for the 2 percent trend you missed while your assessment was reduced), even if that jump is 8, 12, or 20 percent in one year. State guidance confirms there is no limit to how much value can be restored in any given year, up to that factored base year ceiling. The only hard ceiling is the factored base year value itself. The assessor cannot value your property above what it would have been worth under normal Prop 13 trending had the decline never happened.

Why this shows up in the South Bay right now

Coastal South Bay cities, including Manhattan Beach, Hermosa Beach, and Redondo Beach, saw a real dip in comparable sales during recent rate-driven slowdowns, which pushed some assessed values into decline-in-value status through the Los Angeles County Assessor's automatic Prop 8 review. As sale prices recovered, owners who had gotten used to a lower tax bill for a year or two have been surprised by an assessment jump well above 2 percent the following year. That is not an error and it is not a reassessment triggered by a sale. It is the statute working as designed.

What to check on your bill

If your assessed value moved by more than 2 percent without a sale, a remodel, or new construction, look at your Notice of Assessed Value from the LA County Assessor. It will show whether your property has been carried at a Prop 8 (decline in value) figure in prior years. If so, the current year's number is simply catching your assessment back up to the Prop 13 trend line, not exceeding it. You can also request an informal review or file a formal assessment appeal with the county Assessment Appeals Board if you believe the current market value is still below the restored figure, but the burden is on you to show comparable sales data.

What this means for you

Do not assume a 2 percent cap protects you every single year. It only protects an assessment that has been trending normally under Prop 13. Once a property has dipped into decline-in-value status, the door is open for a larger-than-2-percent jump back up, capped only by where your assessment would have landed anyway. Budget for that possibility if your area saw a dip in the last few years and prices have since recovered.

If you would rather someone else keep an eye on your assessment notices and flag anything unusual before your bill arrives, that is part of what we handle for our owners.
