LA County property tax reassessment

What Actually Triggers a Property Tax Reassessment in LA County (and What Doesn’t)

by Stephen Morris CPA, MBT, CCIM


Half the property tax questions we get are versions of, “Will this reassess my building?” The answer matters because a Prop 13 base from years ago is one of the most valuable assets an LA owner has, and it is surprisingly easy to blow it up with paperwork. Two things trigger reassessment: a change in ownership, and new construction. Everything else is myth management.

What does not trigger reassessment

Refinancing. Taking cash out. Transfers between spouses or registered domestic partners. Moving the property into your revocable living trust. Ordinary repairs and maintenance. None of these reassess anything, no matter what a title officer mutters at closing. Do not let reassessment fear stop a refinance that otherwise makes sense.

What does: change in ownership

A sale, obviously. A gift. An inheritance (with the narrow Prop 19 family-home exception covered in our Prop 19 article). Adding a non-spouse to title can be a partial change in ownership, reassessing the share transferred. The County learns about transfers from recorded documents and required filings, and unwinding a mistake after the fact ranges from hard to impossible.

The entity trap: where sophisticated owners get burned

Here is the one that catches families. Move your building into an LLC in the same proportions in which you already own it, and nothing happens—the transfer is excluded. However, the County remembers who the original owners were.

Later, transfer LLC interests, sell more than half, or allow one person to accumulate control, and reassessment may be triggered—sometimes years after everyone has forgotten the rules.

Entity transfers also come with their own state filing obligations, with penalties for failing to comply.

A pattern we often see is that parents form the LLC correctly, then gift membership interests to their children over a decade. The cumulative transfers eventually cross the threshold, but nobody is monitoring them.

The income tax plan and the property tax plan must be managed together, or one can quietly undermine the other.

New construction: additions count; upkeep does not

Build an ADU, add a unit or complete a garage conversion, and the new construction will be assessed and added to your existing tax base.

Replace a roof, repaint or repair plumbing, and it will generally be considered maintenance rather than assessable new construction.

The grey area is a major renovation that is considered “substantially equivalent to new”. If you are planning a full gut renovation, establish how the assessor is likely to view it before applying for permits.

Will refinancing reassess my property?

No. Loans are not considered changes in ownership.

Does putting my building in an LLC trigger reassessment?

Not if the ownership proportions remain identical. The danger comes later, when interests in the LLC begin to change hands.

Track cumulative transfers carefully, or the county will do it for you.

My trust owns my rental. Is that a problem?

A transfer to a revocable living trust is excluded. Irrevocable trusts and trusts involving other beneficiaries are a different matter. Seek advice before recording the transfer.

I am adding my daughter to the title of a rental property. Will it be reassessed?

This is likely to constitute a partial change in ownership relating to her share. Since Proposition 19, there is no rental-property exclusion to prevent reassessment. Likely a partial change in ownership on her share, and since Prop 19 there is no rental exclusion to save it. Talk to us about better routes first.
