Colorado Prices Are Catching Up to California — Unless You Rent

What everyone believes

“Colorado's cost of living is getting close to California's.”

The data's verdictmixed

Ask around Denver and you’ll hear it constantly: rent feels like California now. Housing prices feel like California now. The whole state, the theory goes, is quietly turning into California with better mountains. It’s usually said about one thing — a lease renewal, a house listing — and generalized to two entire states.

The broad claim, checked first

Before zooming into any one city or any one price tag: has Colorado’s overall cost of living actually moved toward California’s? The Bureau of Economic Analysis tracks exactly this — a price-level index for every state, benchmarked to the national average.

Cost-of-living index, Colorado vs. California (U.S. average = 100)
Both lines have barely moved in 16 years. California sits well above the national average; Colorado sits modestly above it. The distance between them today is almost exactly the distance in 2008.
0 years

of BEA price-level data — and the overall cost-of-living gap between Colorado and California has moved by 0.2 points in that time. Statistically flat.

Taken literally, the popular belief is wrong. Colorado has not been closing in on California’s overall cost of living. It never left second gear.

The one thing that actually moved: housing

So where is the “it feels like California now” feeling coming from? Break the same index into its components and one line stands out.

Cost-of-living gap, California minus Colorado (state level)
The all-items gap (the chart above, restated as a single line) hasn't moved. The housing-specific gap has closed by 43% over the same 16 years — California's housing premium eased slightly while Colorado's climbed.

Housing is the one category where Colorado is genuinely, measurably catching up. Everything else in the basket — groceries, utilities, general services — isn’t telling the same story, which is exactly why the belief feels true (people mostly complain about rent and home prices) while the state-level number stays flat.

Zoom into the cities people actually mean

Nobody comparing “Colorado” to “California” is thinking about Grand Junction versus Bakersfield. They mean Denver versus LA, or Denver versus the Bay Area. At that resolution, the convergence is sharper.

Housing cost-of-living gap vs. Denver, by metro
Both coastal metros' housing premium over Denver has shrunk — Los Angeles's gap with Denver is down 61% since 2008; the Bay Area's is down 30%. Denver didn't get cheap. The coast's premium over Denver just got smaller.
0%

— how much Denver's housing-cost gap with Los Angeles has closed since 2008. It's the sharpest convergence of any pair measured on this page.

That’s an index, benchmarked to the national average — useful for comparing regions on the same scale, less intuitive than an actual price tag. So here’s the same story in dollars: typical home value, Denver vs. LA vs. San Francisco, 2008 versus today.

Typical home value, 2008 vs. 2025
Denver's typical home value grew 133% since 2008 — more than LA's 77% or San Francisco's 89%. Denver homes went from 46% of LA's price to 61%; from 42% of San Francisco's price to 52%. Real convergence, not just an index artifact.

Two independent sources — BEA’s relative price index and Zillow’s raw dollar data — agree. Homeownership costs in Denver really have been closing the gap with the coastal California metros people actually compare it to.

The twist: rent didn’t get the memo

Here’s where it gets uncomfortable for the clean version of the belief. Home values converging is a story about buyers, and most people aren’t buying — they’re renting. Zillow’s rent index tells a different story.

Typical asking rent, Denver vs. LA vs. San Francisco
Denver rent grew, but so did LA's and San Francisco's — roughly in step. Denver rent was 72% of LA rent in 2015; it's 65% today. The gap widened, not narrowed.

Two reputable sources on the same general question point in different directions once you split buying from renting. That split — not a single yes-or-no — is the actual finding.

Against San Francisco rent specifically, Denver did narrow the gap a bit (57% of SF rent in 2015 to 61% today) — modest, and nowhere near the homeownership convergence. Against LA, the rent gap didn’t close at all. If “Colorado is getting close to California” is a claim about what it costs to rent an apartment, the data mostly says no.

Why the belief exists anyway

The homeownership story lines up with something real: people actually did move.

0%

growth in Californians filing a Colorado address on their tax return the following year, from the 2009-10 baseline (9,300/year) to the 2020-21 pandemic peak (16,153/year). It's cooled since — 14,044 in 2022-23 — but is still well above where it started.

California-to-Colorado migration (tax returns filed, by year)
A real, sizable increase in California-to-Colorado moves, peaking during the pandemic remote-work era — right when Denver's housing premium over LA was closing fastest. Correlated in time; this doesn't prove which caused which.

There’s also a real financial pull that has nothing to do with home prices. Colorado’s flat 4.40% income tax is a fraction of California’s top marginal rate (13.30%, effectively 14.6% with the state’s payroll surtax on wages above the cap). Colorado’s effective property tax rate (0.50%) is lower than California’s (0.70%) too, though California’s Prop 13 caps assessment growth in ways a headline rate doesn’t capture. None of that is “cost of living” in the price-index sense above, but it’s a second, separate reason a Californian relocating to Colorado plausibly feels like they came out ahead, on top of whatever the housing numbers say.

Verdict

Collapsing this into one yes-or-no would misstate what the data actually shows. Three separate answers, depending on the question actually being asked:

  • “Is Colorado’s overall cost of living catching up to California’s?” No. The state-level, all-items gap hasn’t moved in 16 years of BEA data.
  • “Are Denver home prices catching up to LA and San Francisco’s?” Yes, clearly — confirmed two independent ways, index and dollar terms alike. This is the real phenomenon behind the belief.
  • “Is rent catching up?” Mostly no. Denver’s rent gap with LA actually widened since 2015; the gap with San Francisco narrowed only modestly.

The belief survives as a story about buying a house in Denver specifically — and that part checks out. Stretched to “Colorado” and “California” as whole states, or to renting instead of buying, it doesn’t.

Methodology

BEA Regional Price Parities (RPP) — an index of price levels relative to the national average, US=100 — pulled at state level (California, Colorado) and metro level (Denver-Aurora-Centennial; Los Angeles-Long Beach-Anaheim; San Francisco-Oakland-Fremont), 2008-2024, the full available annual series. Cross-checked against Zillow's Home Value Index (ZHVI, 2008-2025) and Observed Rent Index (ZORI, 2015-2025) in raw dollar terms for the same metros, to see whether an index-based finding held up in the actual market. IRS migration data (2009-2023, by filing-year pair) used for California-to-Colorado tax-return counts as context, not causal proof. Tax figures are 2026 Tax Foundation published rates. Full data, provenance log, and every intermediate calculation: research/colorado-california-cost-of-living/ in the project repo.

Limitations

BEA's RPP data currently ends at 2024 (2025 not yet published); Zillow's series run through December 2025 for comparability, a year ahead of RPP — the two are not from the identical final month. RPP is a relative-to-national-average index, not a literal two-city dollar comparison, though it's designed for exactly this kind of cross-region read since both areas share the same US=100 baseline. 'Denver,' 'Los Angeles,' and 'San Francisco' are metro-area (MSA) figures — they represent those metro regions, not the states as a whole, and rural Colorado and inland California are both far cheaper than any number on this page. The migration trend is shown as context for why the belief exists, not as proof it caused the price trend — no causal claim is made. The tax comparison is descriptive (headline statutory/effective rates only) and doesn't model deductions, credits, or an individual household's actual bill.
