Parcel Duality

Two identical houses sit side by side on a street in the Bay Area. Same lot size, same 1950s floor plan, same view of the same hills. One owner pays about $2,000 a year in property tax. The other pays about $20,000. Neither is cheating, and the county didn't make a mistake. The first family bought in 1978. The second bought last spring.

Most states would find that difference impossible to defend. California takes it for granted. It's what Proposition 13 was built to do, and after almost fifty years it has become the ground the state's housing market stands on.

What Jarvis built

In June 1978, California voters passed Proposition 13, the Jarvis-Gann initiative, by nearly two to one. It did three things that still matter:

• It capped the property tax rate at 1% of assessed value, plus whatever voter-approved bonds sit on top.
• It rolled every assessment back to its 1975–76 value, and after that limited increases to 2% a year, or inflation if lower.
• It said a property could be reassessed at market value only when it changes hands or when something new is built on it.

The anger behind it was real. Through the 1970s, California's land prices rose fast and assessors, newly professionalized after a bribery scandal, were keeping up with them. Retirees on fixed incomes watched their tax bills jump by a fifth or a quarter in a single year on houses they had paid off long ago. They had done nothing different. Their neighborhood had simply become more desirable, and the county was billing them for it. Meanwhile Sacramento was sitting on a multibillion-dollar surplus and not giving any of it back.

Underneath the tax bills was an older fear, about losing the land itself. A property tax is a bill that never ends, and the penalty for not paying it is the property. Someone who paid off a mortgage decades ago doesn't own their house outright in the way they thought. They hold it on the condition that they keep paying whatever the county says it's worth this year, and if the county's number rises faster than their income, the county can eventually sell it out from under them. For people whose house was most of what they had, rising assessments felt like a slow expropriation, carried out by a government that had never had to decide to take anything. Jarvis's movement came out of that sensitivity: the belief that people who hold land have a right not to have it taken away, and that a tax that tracks market value without limit is one way of taking it. Howard Jarvis didn't invent the grievance. He gave it a ballot number.

The market revalues. The government can't.

What Proposition 13 did underneath is simple to state and turned out to reach much further than it sounded in 1978. A property has a value. Before Jarvis, the market and the assessor were at least trying to track the same number. After Jarvis, only the market is allowed to keep looking.

The market reprices every parcel constantly. Every sale on the block, every new transit line, every employer that moves to town, every restaurant that makes a neighborhood fashionable shows up in what the next buyer will pay. The assessor's number, meanwhile, crawls forward at 2% a year from whatever it was on the day of the last sale. In a state where coastal land prices have often grown at several times that rate, the two numbers pull apart a little further every year for as long as the owner stays.

Run the arithmetic on the 1978 house. At the 2% ceiling, compounded for almost five decades, an assessment grows by roughly two and a half times. A house assessed at $60,000 in 1978 sits on the rolls today somewhere around $150,000. Its market value, anywhere near the coast, is ten times that. The county collects tax on a price that has not existed for forty years.

This is a strange arrangement for a government to accept. It is bound by law to value property using a figure it knows is false, while every private party it deals with (the lender, the buyer, the insurer, the heirs) uses the true one.

Deferred, not avoided

The change in value doesn't go away. It waits. Every year of appreciation the assessor isn't allowed to see builds up in the gap between the two prices, and all of it comes due on a single day: the day the property passes to a different owner. On that day the assessment jumps forty years in one step, and the new owner takes on the full tax in their first year.

That is the actual design of Proposition 13. It doesn't spare anyone the effect of rising land values. It moves the effect off the person who has owned the land while it gained value and onto the person who shows up afterward. The seller keeps all of the appreciation in the sale price. The buyer pays that price and also gets the tax bill that should have been rising steadily all along. The disruption Jarvis promised to prevent still happens. It happens at the time of transfer, and it falls on someone else.

Everything below follows from that one choice to defer. Owners avoid the moment of transfer, so they don't sell. Businesses arrange their affairs so that a transfer never legally takes place. Families pass property down in ways the law doesn't treat as a transfer. And the costs that pile up in the meantime land on whoever arrives last.

It's the land, not the house

The gap is almost entirely a land gap, and that is the key to understanding what Proposition 13 actually protects.

Buildings don't appreciate. A 1955 ranch house is an old wooden box with old wiring. Left alone, it loses value every year, and nobody pays $1.8 million in Palo Alto for the drywall. What they pay for is the ground under it: the lot's place in a regional economy, its distance to jobs, its school district, its climate, its neighbors. In the expensive parts of California the land accounts for most of a home's market value, often three quarters or more, and it is the land that appreciated from $60,000 to $1.5 million while the structure sat and aged.

None of that value was made by the owner. It was made by everyone else: the firms that located nearby, the workers who came to staff them, the public spending on roads, water, and transit, and the zoning boards that kept new supply out. Rights and Property made the general case that a claim on a location is partly a claim on value the community created. Proposition 13 is a working example. It takes the one part of a home's value that the owner had least to do with and puts it almost entirely out of reach of the public that created it.

A land value tax, the Georgist remedy this site keeps coming back to, does the reverse. It taxes the ground and leaves the building alone. Proposition 13 effectively untaxes the ground and leaves the building exposed: add a second story or an accessory unit and the new construction is assessed at full current value, while the lot's forty-year appreciation stays frozen. Leave the lot alone and nothing changes. Few tax policies could better reward sitting still on valuable land.

Land is powerful

This matters because land in California is not just a place to live. It is the main store of wealth for most families who have any, and the main source of political power for those who hold it.

Consider what Proposition 13 does to the incentives of an incumbent owner. The market value of their home rises with scarcity. Their tax bill doesn't. So every housing shortage is pure gain to them. They collect the appreciation and pay almost none of the carrying cost that would normally come with holding a more valuable asset. Any new construction that would ease the shortage threatens that gain, and they pay nothing for opposing it. The homeowner who shows up at a planning commission meeting to fight a fourplex is not being irrational. They are defending a position the tax code has made unusually profitable to defend.

Then there is the lock-in. Because the low assessment resets on sale, moving is very expensive for long-term owners. An empty-nester couple in a four-bedroom house would, by moving to a smaller place across town, trade a $3,000 tax bill for a $12,000 one. So they stay. Multiply that across a state and a large share of California's family-sized housing is held by people who would give it up if the tax code let them, while the families who need it rent smaller places farther out. The housing is there. The law makes moving too costly.

The protection didn't stop at homes. Commercial and industrial property got the same treatment, and it has proven even more durable. A corporation does not die, retire, or downsize, and ownership can change through entity transfers structured so that no single buyer ever acquires control, which means no reassessment. Parking lots, warehouses, and underbuilt strip malls bought generations ago sit on some of the most valuable land in the world at carrying costs set during the Carter administration. When voters were offered Proposition 15 in 2020, which would have reassessed large commercial parcels at market value while leaving homes alone, they turned it down narrowly. The homeowner's shield had become cover for everyone else's too.

What the tax does to cities

The distortion doesn't stay inside property. It shapes how cities themselves are run.

Proposition 13 cut local property tax revenue by more than half almost overnight, and fixed the share each jurisdiction would get from the capped pool according to what it had collected before 1978. Cities that had kept taxes low in the 1970s have been stuck with a thin share ever since. Control over school funding moved to Sacramento, which had to backfill what the counties lost. Local government in California became a client of the state in a way it had not been before.

Cities then learned to chase the revenue they could still grow, which was sales tax. A car dealership or a big-box store brings in a steady stream of sales tax and costs little in services. A new apartment building brings in residents who need police, parks, and libraries, while paying property tax at a rate that has to be split with every other taxing district. So a city under Proposition 13 has a structural reason to zone for auto malls and against housing. Planners call this the fiscalization of land use. It's one more pressure pushing in the same direction as the incumbent homeowner.

New subdivisions picked up the slack in another way. Since general taxes now needed a two-thirds vote, developers and counties turned to Mello-Roos districts and special assessments, which put the cost of new roads, schools, and sewers on the buyers of new homes as a separate charge on top of their already full-rate property tax. So the people who arrive last pay the market assessment, pay for the infrastructure the earlier residents got as a shared public expense, and pay more for the house itself because of the shortage the whole system produced.

The adjustments that kept the core

Voters have revisited the arrangement several times, and each change has made the central structure more entrenched rather than less.

Proposition 58 in 1986 let parents pass their low assessment to their children without reassessment, and Proposition 193 extended it to grandchildren. For thirty-four years, a family could hand down not just a house but a tax rate frozen in the 1970s, and could rent the house out at market rates while keeping it. Proposition 19 in 2020 narrowed that to a family home the heir actually lives in, which closed the most obvious abuse, while in the same measure extending portability, so that owners over 55 could carry their low assessment to a new home anywhere in the state. The frozen number is no longer attached only to one parcel. For many owners it has become a personal entitlement that goes where they go.

The result is one of the lowest homeownership rates of any state, around 55%, alongside property tax bills that are among the most unequal between neighbors anywhere in the country. The system Jarvis sold as protection for homeowners has come to protect the homeowners who already had homes.

Keeping the part that was right

It's worth being careful here, because the 1978 grievance was legitimate and any replacement has to answer it. The right not to have one's land taken away is about as basic a property right as there is, and a tax is no less a taking because the process is slow and the notices come on letterhead. A widow should not lose a house she owns outright because a software company opened an office two miles away. That was a real injustice, and it's why Proposition 13 remains popular with people it hurts.

Three things are all true at once. People who hold land have a right not to have it taken from them. The value of land is created by the community and belongs, at least in part, to it. And the market price is the best measure anyone has of what that land is worth. Proposition 13 treats these as incompatible and gives up the second and third to save the first. But only the first and second ever seemed to conflict, and they only conflict if the tax has to be paid in cash, every year, by whoever happens to be living in the house.

It doesn't. A land value tax assessed at the real market price can be deferred for an owner-occupant who can't pay, as a lien against the land that is settled when the property eventually sells or passes to heirs. No one loses their land over a bill they can't pay, because the bill is never enforced by taking the land while they hold it. The widow stays in her house. The public's claim on the value it created still accumulates and is collected when the land changes hands. The assessor is allowed to see what the market sees.

Notice that this defers to the same moment Proposition 13 does: the transfer. The timing was never the problem. What Proposition 13 gets wrong is who pays when that moment comes. Under Jarvis, the tax that went uncollected while the land gained value is simply forgiven, and the next owner starts paying the full rate. Under a deferral lien, the tax that went uncollected is paid out of the proceeds by the party who received the appreciation, and the next owner starts on the same terms as everyone else. Both make the reckoning wait until a sale. Only one sends the bill to the person who got the gain. Transitioning to LVT works through how such a change could be phased in without taking value from anyone who bought under the current rules.

Getting from Jarvis to a land value tax also means finding a revenue-neutral version of it: one that, on the day it takes effect, collects the same total that property taxes collect now, only divided differently. That matters for more than politics. Proposition 13 is written into the state constitution, so replacing it takes a statewide vote, and voters who hear "new tax" will not look past the headline. A revenue-neutral land tax isn't a new tax. It's the same amount of money raised from a different base. And because the full market value of California's land is so much larger than the frozen roll the assessor works from now, the rate needed to raise the same revenue could be well below today's 1%. The owners who bought recently, and anyone who builds, would pay less. Those sitting on long-held land, especially the old commercial parcels, would pay more, with deferral for the owner-occupants who can't. Settling on that base, that rate, and that schedule in a form people can check for themselves is the real work of any transition. Until it can be shown that the change moves the bill without raising it, the argument for a land tax will keep losing to the fear that it is just a larger tax under a better name.

What Jarvis set out to protect was a person's hold on their land. What the law ended up sheltering was the land's value, which was never theirs alone. Separate the two, protect the person directly, and let the government see the same price the market sees, and most of the distortions described here lose their reason to exist: the lock-in, the incentive to oppose new housing, the underused commercial lots, the cities zoning for car dealerships. Land would still be powerful in California. It would just stop being subsidized.
