The quick read

Residential permitting has slowed: 15 units authorized over the past twelve months, 32% below the prior year.

Buying strains local incomes far more than renting does — the median home is 9.1 times median household income, against a historic benchmark near three — while rent takes 19% of it.

Physical-risk exposure is above the national median, driven mainly by inland flooding, earthquake and coastal flooding.

Occupational employment and wages are published for metropolitan areas rather than for individual cities or ZIP areas, so these describe the wider labor market this location sits in. 2025 OEWS, U.S. Bureau of Labor Statistics.

The Bureau of Labor Statistics publishes city-level labor data only for places of 25,000 or more. This is the figure for Marin County, CA, which contains this city.

Housing & affordability

How it’s calculated →

Prices for everything a household buys run about 18% above the national average, on the Bureau of Economic Analysis index. Housing drives most of that difference.

Median rent of $2,797 takes 19% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 9.1 times median household income here, well above the historic benchmark, at a level conventionally described as seriously unaffordable.

Cost of living
117.6

Prices here run about 18% above the national average. The spread between places is driven mostly by housing — goods vary far less — and this excludes taxes.

Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.

Permitting is increasing — 2 consecutive years, measured from 2020 to 2025.

An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.

Population has fallen 1% since 2020, reaching 12,645 in 2024.

New construction is predominantly single-family: only 0% of permitted units are in buildings of five or more homes.

At 1.2 permitted units per 1,000 residents, building activity is below the median for measured US cities.

Weather & climate

9 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 66°F and January a low of 47°F.

Normal annual precipitation is 22.9 inches.

Air quality measures a median index of 28, in the Good band, and no day in the year passed 100.

unhealthy for sensitive groups

A comfortable median and a bad tail are different problems. Wildfire smoke and summer ozone show up in the worst tenth of days, not in the middle of the year.

Climate figures are thirty-year normals, not current conditions. They describe what a typical year looks like rather than what the weather is doing today. Air quality is measured rather than modelled, by EPA monitors, and published by county only where a monitor sits — roughly half the counties AreaProfile publishes have one, and the rest show nothing rather than an estimate. Air masses are regional, so a county reading describes the air over a place reasonably well, but it is still the county reading.

Physical risk

33 / 100
Physical resilience

The hazards accounting for most of this area's expected annual loss are inland flooding, earthquake and coastal flooding.

EarthquakeHigh
Coastal floodingHigh
Inland floodingHigh
WildfireModerate
TsunamiModerate

Low or minimal exposure: landslide, heat wave, volcanic activity, drought, lightning, tornado, strong wind, winter weather, hail.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA publishes at county level. City values are the population-weighted mean of the counties the city overlaps, using AreaProfile place-to-county land-area weights. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.

These are deaths, not offences — they say nothing about burglary, theft or assault.

Marin County records 1.2 homicide deaths per 100,000 residents a year, lower than most counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 4.3 per 100,000 — more than the homicide rate, because nationally most firearm deaths are suicides.

Drug overdose deaths run at 16.9 per 100,000 residents in Marin County.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides. The two columns overlap and should not be added.

Age-adjusted rates from provisional death certificate records, published by the CDC for Marin County as a whole — these rates are not published below county level. A county can hold both a dense city centre and a suburb whose experience of it is nothing alike, so this describes the county around San Anselmo rather than San Anselmo itself. That is why AreaProfile shows these figures and does not put them in the Area Score. Where fewer than ten deaths were recorded the count is suppressed at source, and a rate built on single figures moves sharply between releases. What this measure has that reported crime does not: a death certificate is filed whether or not the local police agency submitted a return that year, so the figures stay comparable between places and over time.

What this profile does not cover

Three things people look for are missing from every AreaProfile page, and each is missing for a reason rather than by oversight. The Area Score is calculated without them and the weighting is documented on the methodology page.

Reported crime
Offences reported to police are published by department rather than by town, and only where a department reported every month of the year. No municipal department reports for this place — many smaller communities are policed by the county — so there is no figure to show. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.
Taxes
Taxes are not published: no source covers them nationally with a method open enough to check. Cost of living now is — the index above is the Bureau of Economic Analysis price parity for this area — but it is a price level for all consumption rather than a budget for a household, its spread is driven mostly by housing, and it excludes taxes. Housing affordability is computed separately from rent, price and income, because that answers a narrower and more actionable question. Nothing here is individualised tax advice.
Anything about a specific address
Every figure describes an area, not a street or a house. School attendance zones, insurance pricing and the character of a neighbourhood all vary within the places measured here.

Access

Airport identity, position and runway data come from the FAA. “Major airport” is an AreaProfile classification — a public-use civil airport with a paved runway of at least 8,000 feet — not an FAA hub designation. Distances are straight-line, not driving distance.
