You probably had an answer to that before you even finished reading the question. But I’m willing to bet it’s not the whole answer. There are a lot of things that go into building housing, and California is a big place, so different things might matter more in different places.
If you’re reading this blog, odds are the first thing that came to your mind is zoning. In the already-dense built-up parts of LA and OC, zoning is indeed the most likely culprit, since it is simply illegal to build more housing on most of the land. But go further east, and there’s lots of land zoned for residential development, yet prices are still much higher than comparable locations in other states. Looking at this could help shed light on factors other than zoning.
The Inland Empire Should be as Affordable as Phoenix
Here’s a look at the cheapest offerings in the Inland Empire and in Phoenix from DR Horton, one of the biggest homebuilders in the US, and of the big builders operating in California, probably the most focused on trying to build entry-level homes.
The cheapest offering in Phoenix is $136k; in the IE, $264k, making the cheapest new construction in the IE almost twice as costly as Phoenix. That’s quite a difference. In terms of amenities, the IE does better than Phoenix – driveable to SoCal’s beaches, close to a bigger urban center in LA, closer mountains, better climate – but not enough to justify that margin. And it terms of wages, Phoenix passed the IE after the Great Recession and has seen substantial wage growth in the last two years, while IE wages have been stagnant. So not only are IE residents getting hit with higher housing costs; their wages aren’t keeping up. Small wonder that the Phoenix MSA was the fastest growing region of the country last year, adding 82,000 people.
Taking all of DR Horton’s projects in the IE and in Phoenix, plus projects from Pardee Homes (another entry level builder) in Riverside County to fill things out a little, here’s the cheapest house offered in each subdivision, plotted against distance from the bedroom community to the central city.
As we’d expect, housing gets cheaper the further we get from the central city. You might look at this and think that the IE could hit Phoenix levels of affordability another 20 miles out, but cheap housing that far from the center city wouldn’t really do much to help. People will commute from Buckeye to Phoenix; no one is commuting from Barstow to LA. (Note: the low-cost developments close to Phoenix are all in South Phoenix, a historically black and Latino neighborhood that faced all the systematic discrimination and disinvestment you’d expect.)
Replotting the data looking at the cheapest house offered in each subdivision against the size of the house is very revealing.
The smallest new houses in the IE are in the neighborhood of 1,600 SF (though I know KB Home has a project at 1,430 SF), while in Phoenix many project are around 1,250 SF and one is as low as 1,100 SF. This is counterintuitive to housing prices being higher and wages being lower in the IE; we’d expect to see smaller houses in the IE than in Phoenix. The incremental cost per square foot is not substantially different between the two regions, but IE housing developments appear to face structural issues that add about $100k to the cost of a house. The same issues are probably responsible for making small houses infeasible in the IE.
Now looking at the largest house offered in each subdivision, let’s plot the cost per square foot versus distance from the city center.
While there will always be variability between municipalities, the overall trend is what you’d expect – cost per square foot declines as you move further from the city. This is a proxy for how much people value being able to live closer to the center.
Finally, let’s look at cost per square foot versus house size.
The cheapest new construction in the IE is around $120/SF (though KB Home has a project in Victorville that hits $100/SF) while in Phoenix many projects are under $100/SF. Note that cost per square foot doesn’t seem very impacted by house size; this is because we’re looking across the whole region. Within a given subdivision, house prices per square foot are always lower for larger houses.
Why is IE Housing So Expensive?
I think this should prompt a deeper look at what goes into the cost of building housing in California. Starting from the bottom up, the inputs to housing are:
The most basic input to housing is having a place to build. Unlike in LA/OC, there’s still a lot of greenfield land in the IE that is zoned for residential development or has approved master plans. High housing costs should bring that land to market to be developed.
Here is a plot of the difference between IE and Phoenix home prices, with a breakdown of the delta into structure costs and land costs.
With the exception of a strange jump in 2011 (that almost suggests a change in methodology of the underlying component data), the structure delta is remarkably stable throughout the housing bubble, Great Recession, and recovery. $20k to $30k of the price difference between the IE and Phoenix is in the physical structure itself. The large swings are driven entirely by land, with IE land prices rising higher than Phoenix during the bubble and recovery, and crashing to par during the recession.
This pattern suggests a structural issue with land availability. This could be due to second-order factors like CEQA, though as noted above there are many greenfield sites where master plans are already approved. However, another possibility is that in California, the inefficient property tax structure resulting from Prop 13 decreases the penalty for land speculation, because taxes do not keep pace with land values. In Arizona, property assessments increase with the value of the property and the increases are not capped like they are through Prop 13. Another possibility is that ownership of developable land in the IE is more concentrated, making collusion to drive up prices easier.
Zoning drives up the cost of housing by limiting the number of houses that the cost of land can be spread across. A detailed analysis of density and zoned capacity in the IE and Phoenix is well beyond the scope of this blog. However, as an example, consider the general plan of Buckeye, a growing suburb west of Phoenix with very affordable housing. Much of the city is zoned for 3-6 dwelling units per acre (du/ac), which is typical of “medium density” zoning found in many IE master plans.
General Impact Fees
General development impact fees are fees imposed by cities on new development that are intended to pay for the costs of providing public services to the new development. Again, a comprehensive review of general impact fees is beyond the scope of this blog.
However, like with land costs, the long shadow of Prop 13 means that basic structure of taxation and municipal finance in California lends itself to high development impact fees. Unable to reassess properties to true market value or increase the tax rate, and limited in their ability to assess fees by subsequent propositions, California cities increasingly rely on development fees to plug holes in municipal budgets. Young cities in the Inland Empire, such as Jurupa Valley and Menifee, as well as other inland cities that have annexed land in recent years, face additional budget shortfalls as a result of faulty city finance legislation passed by the state during the financial crisis. The convoluted system of state funding to municipalities is itself a legacy of Prop 13.
To take some example, the city I live in, Glendale, charges a fee of $18,751 per multi-family unit (page 115 of 146) and $21,828 per single-family unit for parks alone. That fee could easily be expected to add $100-$150/month to baseline rents. In the Inland Empire, cash strapped cities have driven total impact fees up as high as $65,000 per unit in Riverside County and $75,000 per unit in San Bernardino County – around 25% of the cost of some of the cheapest development.
Meanwhile, the city of Buckeye charges literally no parks fee on most new residential development. The sum of parks, library, streets, public safety, water, and wastewater fees ranges from about $10k in the lowest cost districts to $20k in the highest cost districts. Across Maricopa County in Surprise, the sum of fire, police, library, parks, general government, public works, water, and wastewater fees is similar, ranging from about $10k to $18k. Surprise charges a parks fee of $785 – less than 5% of what Glendale charges, despite Glendale being a major secondary central business district with a large commercial tax base and large sales tax generators.
Lastly, it should be noted that impact fees can be used outright as a way for NIMBYs to stop development, since higher fees will decrease construction.
Special District Fees
Special district fees, or community facilities districts, more commonly known as Mello-Roos fees in California, are additional property taxes assessed in special districts to fund improvements such as streets, water, drainage, schools, parks, and so on. Mello-Roos fees are assessed as parcel taxes, not based on real value, so the actual burden is much higher for lower value parcels. This encourages the development of larger, more expensive houses, because there is “more house” to spread the cost across. As far as I know, there’s no equivalent in Arizona.
The cost of materials fluctuates with both the supply of materials available and the demand for construction materials. While this could have national impacts, there is little reason to suspect the market for materials is so different between SoCal and Arizona that it would drive a regional difference in the cost of construction.
Without doing much in the way of detailed investigation, we can say with some certainty that California’s building code has more stringent requirements. First, the seismic detailing required for safe construction in California should result in some increase in costs. Second, California has famously high standards for energy efficiency for new construction. It’s hard to say off-hand what the cost impact is, but these aren’t things we’d want to compromise on anyway.
California does appear to have higher construction labor costs than Arizona. Ideally, this would be a comparison between residential construction workers in the IE in Phoenix; however, data doesn’t seem to be available for residential construction, and I could only find California at the state level.
According to the NAHB, a single-family home generates 3 full-time jobs for a year. If IE labor costs were about $300/week higher than Phoenix, that would be almost $50,000 per house. However, builders should respond to higher labor costs by trying to use less labor, and higher-wage labor tends to be more efficient than low-wage labor. In addition, labor costs will scale with house size, so the impact of labor costs should be less on smaller houses.
This is a squishier thing to measure than land and impact fees, since there is no way to spread the cost of land out over more units than the zoning allows and no way to evade impact fees. Note that the NAHB’s estimate of average wages and salaries in building a single-family home is literally greater than the purchase price of the cheapest single-family construction in Phoenix. Finally, it should go without saying that driving down wages results in negative social outcomes in a way that decreasing the profits of land-owning rentiers or reducing exorbitant impact fees does not.
Soft costs – such as engineering, permitting consultants, architects, and so on – should vary more or less according to regulatory complexity, so if it is more difficult to permit new housing, higher soft costs would result.
Longer times between purchase of the land and sale of the home will result in higher carrying costs, both because of the additional interest that accrues over that time and the fact that longer lag times make projects riskier. An analysis of the impacts of this factor is well beyond the scope of this blog, but cities should do all they can to reduce the time frame and provide certainty in the permitting process.
There are many factors that drive the cost of building new housing. If California is serious about reducing the housing shortage in the state, it must look to and study regions that build new housing at lower costs, understand which factors are the largest cost drivers, and work to alleviate those factors that can be improved in a socially and environmentally responsible manner.

A podcast on Market Urbanism, or the cross between free-market policies and urban issues. We discuss how a liberalized urban approach would lead to more housing, faster transport, improved public services, and better quality of life. Tap to listen.
Market Urbanism Report is sponsored by Panoramic Interests, a progressive developer in San Francisco. Panoramic, which is owned by Patrick Kennedy, specializes in 160 sqft micro-units (called MicroPads) that are built using modular construction materials. Panoramic has long touted these units as a cost-effective way to house San Francisco’s growing homeless population. But Panoramic also builds larger units of between 440-690 sqft. To learn more about Panoramic’s micro-unit model, read MUR’s coverage on the firm in its America’s Progressive Developers series. Or visit Panoramic’s website.
Market Urbanism Report is a media company that advances free-market city policy. We aim for a liberalized approach that produces cheaper housing, faster transport and better quality-of-life.
Market Urbanism is a theory calling for free-market solutions to urban problems. Rooted in classical liberalism, it posits that cities work best through the bottom-up, private sector activity of many individuals, not top-down government plans. In this nifty guide, Scott Beyer describes how these free-market ideas can apply to housing, transport and public administration. You can purchase the book (including one signed by the author) below.
