How Prop 19 Works For Roseville Move‑Up Buyers

Thinking about moving up to a larger or newer home in Roseville but worried your property taxes will jump? You are not alone. Many Placer County homeowners want more space or different features, yet hesitate because they have a low tax base under Prop 13. The good news is that California’s Prop 19 can help eligible owners transfer a lower assessed value to a new primary residence, which can make a move more affordable. In this guide, you will learn how Prop 19 works, who qualifies, how the tax math is calculated, and the practical steps to use it in Roseville. Let’s dive in.

Prop 19 in plain English

Prop 19 lets eligible homeowners transfer the assessed value from their current primary residence to a new primary residence anywhere in California. Before 2021, most transfers were limited to the same or participating counties. Prop 19 removed that barrier for eligible claimants and updated several rules so more people can use the benefit.

When you buy a replacement home that costs more than your original home, the assessor adds only the difference in market value to your old base. If you buy a home that costs less than your original, you generally keep your old base without a downward reset beyond standard Prop 13 rules. Either way, portability can lower the taxable value of your next home compared to starting fresh at full market price.

This matters for move‑up buyers because you can often increase your home’s size or features while keeping your property taxes closer to what you pay now than you might expect.

Who qualifies in California

You can claim a Prop 19 transfer if you meet one of these eligibility categories:

• You are age 55 or older at the time of transfer.
• You are severely disabled.
• You lost your primary residence to a wildfire or other qualifying disaster.

To use the benefit, you must transfer the assessed value from your current primary residence to a replacement primary residence in California. The replacement property must become your principal residence. If you do not meet one of the eligibility categories, you generally cannot transfer your base under Prop 19.

Prop 19 also expanded how many times eligible owners can transfer their base compared to older rules. The exact number and any exceptions should be confirmed with state guidance and the Placer County Assessor.

How the tax math works

The assessor starts with your current home’s base‑year value. Then the assessor compares market values and adjusts if the replacement home costs more than the original. Here is the general idea for a replacement that costs more:

• New assessed value = your original base‑year value + (replacement market value − original market value).

If the replacement costs less than the original, the base transfers without a downward reset beyond normal Prop 13 rules.

Example for illustration only

• Original home base‑year value: $300,000.
• Original home market value at time of sale: $700,000.
• Replacement home market value (purchase price): $900,000.
• Difference: $900,000 − $700,000 = $200,000.
• New assessed value: $300,000 + $200,000 = $500,000.

Approximate annual property tax is about 1 percent of assessed value. In this example, that would be about $5,000, plus any voter‑approved parcel taxes, Mello‑Roos, and special assessments that apply to the replacement property.

What stays the same: Mello‑Roos and assessments

Prop 19 portability does not remove local charges that are tied to a specific property. In Roseville and across Placer County, many homes carry additional amounts on the tax bill, including:

• Voter‑approved local bonds and parcel taxes.
• Community facilities districts (Mello‑Roos), common in many newer subdivisions and planned communities.
• Special assessments for services like landscape and lighting.

These items still apply to your replacement property even if you transfer a lower base. Before you write an offer, review the property’s tax disclosures so you understand the full tax picture, not just the base rate.

Roseville specifics to keep in mind

Roseville offers a wide range of neighborhoods, from established areas to newer master‑planned communities. Newer areas are more likely to have Mello‑Roos or special assessments. Those costs can be significant and are not reduced by Prop 19.

Placer County processes Prop 19 claims with specific forms and documentation. Filing is not automatic. You will need to work with the Placer County Assessor to submit the claim, verify timing, and respond to any requests for more information.

Step‑by‑step checklist to use Prop 19

• Confirm eligibility
  • Verify you are 55 or older, severely disabled, or a qualifying disaster victim.
  • Confirm your original home is your principal residence.
• Gather documents for your original property
  • Deed and most recent property tax bill showing assessed value.
  • Proof it was your principal residence, such as driver’s license or voter registration.
• Gather documents for your replacement property
  • Purchase contract, closing disclosure or settlement statement, and deed when recorded.
  • Any occupancy statements or affidavits required by the county.
• File your claim with the Placer County Assessor
  • Obtain the current base‑year transfer claim form for Prop 19 and complete it.
  • Include proof of eligibility and required documents.
  • Confirm the filing window and whether you can submit at or before closing.
• Coordinate with escrow, title, and your lender
  • Tell your closing team that you plan to claim Prop 19.
  • Ask how tax proration and provisional amounts will be handled at closing.
  • Make sure your lender understands the timing of the assessor’s adjustment.
• After filing
  • The assessor reviews your claim, may request more info, and then issues the adjusted assessed value.
  • Continue paying any provisional tax amounts until the adjustment appears on your bill.

Timing and sequence questions

Many buyers ask if they need to sell before they buy. Prop 19 allows a transfer when you purchase a replacement primary residence, as long as you can show the base‑year value comes from an eligible original residence. The exact sequence and documentation can vary, so confirm the acceptable timing with the Placer County Assessor and your escrow team.

If you are building or buying new construction, the county may use the value at completion for the market value calculation. Ask the assessor how market value will be determined for your specific situation.

Processing times differ across counties. Some places make provisional adjustments at closing, while others update the assessment after your claim is approved and then issue an adjusted bill. Check with Placer County for current timing.

Common move‑up scenarios

• Buying a more expensive home in Roseville
  • Your taxes may rise, but typically by less than they would if the new home were assessed at full purchase price.
• Moving to another California county
  • Eligible claimants can transfer their base anywhere in the state. You will file the claim in the county where you buy the replacement property.
• Buying new construction
  • Expect the assessor to use the market value when the home is complete or as otherwise determined by county rules. Confirm details before you close.
• Planning multiple moves over time
  • Prop 19 expanded how many times eligible owners can transfer. Confirm current limits and documentation needs with the county.

Avoid pitfalls and plan ahead

• Do not assume portability is automatic. You must file a proper claim and provide documentation.
• Budget for Mello‑Roos and parcel taxes on the new property. These charges are not reduced by Prop 19.
• Coordinate early with the assessor, escrow, title, and your lender so tax proration and loan qualification align with the expected assessment.
• If you are close to age 55, check the exact eligibility date required for your transaction.
• If inheritances or family transfers are part of your plan, note that Prop 19 changed inheritance exclusions. Those rules are separate from portability.

Plan your Roseville move with clarity

If you are trying to decide whether to remodel, stay put, or move up, Prop 19 can give you more flexibility. The key is to run the numbers with your likely purchase price, your current assessed value, and the replacement property’s local assessments. That way, you can compare the real monthly cost of each option and choose with confidence.
