Lawmakers in Sacramento are currently hyper-focused on a ghost. They are chasing software. Specifically, they are targeting price-optimization algorithms used by large landlords, claiming these digital tools are the primary engine behind California’s skyrocketing rents. It is a convenient narrative for a politician because it provides a clear villain with a face made of lines of code. However, the math does not support the outrage. If every rent-setting algorithm in the Golden State were deleted tomorrow, the average tenant would not see their monthly payment drop by a single dollar.
The crisis is not a product of data science. It is a product of simple, brutal arithmetic involving a decades-long failure to build enough roofs. California has created a massive supply deficit that no amount of antitrust litigation against software companies can fix. To understand why your rent is high, you have to look past the computer screen and into the physical world of zoning maps, permit delays, and the "Not In My Back Yard" (NIMBY) sentiment that has strangled the state’s urban centers for fifty years.

The Mirage of Algorithmic Collusion
The current legal crusade against companies like RealPage suggests that landlords are using shared data to artificially inflate prices. Critics argue that by using the same software, competing property managers are essentially forming a digital cartel. This theory assumes that the software has some magical power to override the laws of supply and demand.
It doesn’t. More reporting by Financial Times explores related views on this issue.
An algorithm is a mirror, not a hammer. It looks at historical data, current occupancy rates, and what the building down the street is charging. If a landlord tries to set a rent that the local market cannot support, the unit sits empty. An empty unit earns zero dollars. No software in the world can force a tenant to pay $4,000 for a studio apartment if there are five other identical studios available for $3,000 nearby. The software only "raises" rents when it detects that there are more people looking for homes than there are homes available.
Focusing on the software is like blaming a thermometer for the fever. The thermometer tells you the patient is sick, but breaking the glass won't lower the temperature. In California, the "fever" is a housing shortage estimated to be between 2 million and 3.5 million units. When you have that kind of scarcity, prices go up whether a human or a machine is doing the math.
The High Cost of the Paper Shield
While the public is distracted by the "evil algorithm" narrative, the real barrier to affordable living remains the California Environmental Quality Act (CEQA). Originally intended to protect the state’s natural beauty, CEQA has been weaponized by local interest groups to stall, shrink, or kill housing projects that have nothing to do with environmental degradation.
In many coastal cities, a single disgruntled neighbor can file a CEQA lawsuit to stop a multi-family apartment complex. These legal battles can drag on for years, adding millions of dollars in holding costs and legal fees to a project. By the time the first shovel hits the dirt, the developer has to charge higher rents just to break even on the investment.
Consider a hypothetical scenario where a developer wants to build 100 units of "workforce housing" near a transit hub. Under current conditions, that developer might spend five years in the "entitlement" phase. They pay interest on loans. They pay architects. They pay lawyers to fight off CEQA challenges regarding "neighborhood character" or "shadows."
If the project is finally approved, the cost of those five years of delays is baked into the monthly rent of every tenant who moves in. The algorithm didn't create that cost; the regulatory environment did.
The Suburban Stranglehold
California’s geography of exclusion is written in its zoning codes. For a century, the state has prioritized single-family homes over every other type of dwelling. This has created a low-density sprawl that makes it impossible to house a growing workforce in the places where the jobs actually are.
When a city zones 75 percent of its land for single-family homes only, it is effectively outlawing affordability. It ensures that the only way to add new residents is to push them further into the desert or the forest, increasing commute times and carbon emissions.
The Density Gap
To stabilize prices, California needs "missing middle" housing—townhomes, duplexes, and small apartment buildings. These are the types of homes that provide a bridge between luxury high-rises and suburban mansions. Yet, in many California jurisdictions, these structures are still functionally illegal or burdened with "impact fees" that make them financially non-viable.

Impact fees are another hidden tax on renters. Some cities charge developers $50,000 to $100,000 per unit in fees before a single nail is driven. These fees supposedly pay for parks, sewers, and schools. While these services are necessary, putting the entire financial burden on new construction ensures that new housing will always be expensive. It protects existing homeowners from tax increases while shifting the bill to the next generation of residents.
The Rent Control Trap
When prices get too high, the instinctive political reaction is to cap them. Rent control sounds like a compassionate solution, and for the lucky few who are already in rent-controlled units, it is a lifeline. But as an industry-wide fix, it often backfires.
Strict rent control discourages developers from building new rental stock. If they can’t see a path to a reasonable return on investment because of price caps, they will simply build condominiums for sale or move their capital to a different state altogether. Furthermore, it discourages current landlords from maintaining their properties. If the rent is capped but the cost of labor, lumber, and taxes continues to rise, the building eventually falls into disrepair.
The result is a stagnant market. People in rent-controlled units never move, even if they no longer need the space, because they can’t afford to pay market rate elsewhere. This reduces "churn" in the market, making it even harder for newcomers or young families to find a place to live.
Why the Algorithm Narrative Persists
If the data shows that supply is the issue, why are we seeing a wave of anti-algorithm legislation? Because building housing is politically difficult. It requires standing up to wealthy homeowners who vote in every local election and who view any new apartment building as a threat to their property value.
Attacking a software company in Texas is easy. It requires no political courage. It doesn't offend any local voting bloc. It allows politicians to claim they are "fighting for the little guy" without actually solving the structural problems that keep the little guy broke.
We have seen this play out before. In the 1970s, the focus was on "greedy developers." In the 1990s, it was "foreign investors." Today, it is "big tech algorithms." The villain changes, but the vacancy rate stays at historic lows.
The Path Out of the Crisis
There is no version of the future where California becomes affordable without a massive, sustained increase in construction. This requires more than just "encouraging" growth; it requires stripping local governments of the power to say "no" to projects that meet state standards.
The state has made some progress with "Builder’s Remedy" laws, which allow developers to bypass local zoning if a city hasn't met its state-mandated housing goals. We are seeing the first wave of these projects now, and the backlash from local city councils has been fierce. This is the real frontline of the housing war. It is a battle between those who want California to be a functional state for everyone and those who want it to remain a gated community for the wealthy and the established.
Real Solutions vs. Political Theater
A real strategy for California would look like this:
- Standardizing building codes across the state to reduce architectural and engineering costs.
- Replacing per-unit impact fees with broader infrastructure funding mechanisms.
- Creating a fast-track legal process for housing disputes to prevent years of CEQA-related delays.
- Ending the prohibition on multi-family housing in transit-rich areas.
These are not "market-disrupting" ideas. They are the basic requirements for a healthy economy. When people spend 50 percent of their income on rent, they aren't spending it at local businesses. They aren't saving for retirement. They aren't starting families. The housing shortage is a massive drag on the entire California economy, siphoning wealth away from workers and into the hands of landholders.
The Hard Truth
The focus on rent-setting software is a distraction from the uncomfortable reality that California’s housing crisis is self-inflicted. It is the result of thousands of small decisions made in city hall basements over the course of decades. Every time a duplex was rejected, every time a permit was delayed by six months, every time a height limit was lowered to "preserve views," the price of living in California went up.
Stop looking for a conspiracy in the code. The problem is in the dirt. Until the state allows enough wood and concrete to be stacked on top of that dirt to house its population, the numbers on the screen will keep climbing, algorithm or no algorithm.
If you want to lower the rent, you have to build the house.
