Prop 19 For Pleasanton Moves: Portability & Inheritance

If you are planning a move in or out of Pleasanton, or you are settling a family home, Proposition 19 can shape your property tax bill in a big way. You want clarity before you list, buy, or record a deed. In this guide, you will learn how Prop 19’s portability and inheritance rules work for Pleasanton and Alameda County, what to file, and the common pitfalls that trip up families. Let’s dive in.

Prop 19 changes in Pleasanton

Prop 19 changed two core rules that affect Pleasanton homeowners. First, eligible owners can transfer their property tax base to a new primary residence in California. Second, parent-to-child and certain grandparent-to-grandchild transfers are now much more limited.

Because Pleasanton prices are high, these rules can mean thousands of dollars per year in taxes. Portability may lower taxes when you move if you qualify. Inheritance rules can raise taxes if the property does not meet the new principal residence test and value limits.

Portability: keep your tax base when you move

Who qualifies

You may be eligible to transfer your base-year value if you are age 55 or older, severely disabled, or you lost your primary residence in a qualifying wildfire or other disaster. The replacement property must become your principal residence. Always confirm eligibility and documentation with the Alameda County Assessor.

What counts as a replacement home

Your replacement home can be anywhere in California if you make it your principal residence. Portability works across counties, including moves into or out of Alameda County. Be prepared to show proof of ownership and occupancy for both the original and new home.

How the calculation generally works

When you transfer your base, the assessor compares the market value of your original home and your replacement home. If your replacement is more expensive, the transferred base may be adjusted upward by the difference. If your replacement is less expensive, you may carry your original base without an upward adjustment. The exact calculation and limits are set by law and applied by the assessor.

A quick Pleasanton example

Imagine your Pleasanton home has a taxable value of about $200,000. You buy a replacement home for around $1,200,000. Under portability, you may be able to carry much of that $200,000 base to the new home with an adjustment based on the price difference. Your new assessed value can be far lower than a full reassessment at $1.2 million. The assessor will compute the final number.

Timing and filing steps

There is a required filing window tied to selling your original home and buying your replacement. The number of allowable transfers is limited. Because timing matters, contact the Alameda County Assessor as early as possible for current forms and deadlines. Keep all closing statements and ID ready.

Portability checklist

• Confirm eligibility based on age, disability, or disaster status.
• Call the Alameda County Assessor to request the base-year value transfer claim and filing window.
• Keep closing statements from both the sale and the purchase.
• Prepare proof of principal residence for the new home.
• Submit your claim promptly. Follow up on any notices.
• If you disagree with the calculation, ask for clarification or appeal within the allowed period.

Inheritance and family transfers after Prop 19

What changed

Before Prop 19, many parent-to-child transfers avoided reassessment, even for second homes. Today, most transfers are reassessed to market value. The main exception is a transfer of the family home when the child (or eligible grandchild) will occupy it as a principal residence and the value fits within a statutory cap.

When an exclusion may apply

To preserve some of the original taxable value, the home must be the family home, and the child must use it as a principal residence. An exclusion applies up to a capped amount set by law. Any value above that cap can be reassessed. You must file a claim with the county to secure the exclusion.

Practical Pleasanton scenarios

• Child moves in and files: If the Pleasanton home becomes the child’s principal residence and meets the cap, part of the original tax base may be preserved. The portion above the cap may be reassessed.
• Rental or vacation property: Transfers of non‑primary residences are generally reassessed at market value, which can raise annual taxes.
• Title transfer without occupancy: If the child does not make the home a principal residence, expect reassessment.

Documents to gather

• Recorded deed for the transfer.
• Death certificate for transfers at death.
• Trust documents or will, if applicable.
• Proof of relationship and occupancy as principal residence.
• Any closing statements or supporting records.

Filing and timing

You must file a claim with the county assessor to request any exclusion. Filing windows and acceptable proof of occupancy are set by the county. Contact the Alameda County Assessor to confirm the correct form and deadlines for your situation.

Estate planning tips for Pleasanton families

Because Pleasanton values are high, reassessment can be costly if the home will not be a principal residence for the child. Before you record any deed, talk with an estate planning attorney and tax advisor. Consider the broader plan, including trusts, timing of transfers, and the potential to keep or sell the property.

Who to contact in Alameda County

• Alameda County Assessor’s Office for eligibility, forms, and calculations.
• Alameda County Recorder/Clerk to record deeds and verify recordings.
• Alameda County Tax Collector for tax bills and payment schedules.
• Probate court clerk or the county self-help center for probate-related transfers.
• Trusted professionals: a real estate attorney, estate planning attorney, CPA or tax advisor, and a local real estate agent who knows Pleasanton values.

Common pitfalls to avoid

• Recording a deed before you understand the tax impact.
• Assuming all parent-to-child transfers avoid reassessment.
• Missing filing windows or failing to file the assessor’s claim after recording a deed.
• Confusing portability rules with inheritance rules, which are separate programs.
• Underestimating how Pleasanton pricing magnifies tax changes.
