Adjust to match your bills

What you knowTrash cartThe price is set by the size of your garbage cart and includes two organics carts and a recycling split cart. These are the Town's 2026 maximum rates (a 4.04% increase over 2025). Homes served by the small truck pay more (32 gallons: $68.77 a month).

Value before exemptionsEnter your assessed (net) value from your tax bill: under Prop 13 it is often well below what the house would sell for. The wildfire tax is $0.1141 per square foot of building (shown for 2,000 sq ft), so that line varies by house. All seven San Anselmo tax rate areas carry the same rates in the 2025-26 rate book. San Anselmo voters chose in March 2024 to withdraw the Town from Marin Flood Control Zone 9 (Measure F), so we did not count the Ross Valley storm drainage fee Larkspur homes pay; if your bill still shows one, add it. We did not read a 2026-27 San Anselmo tax bill, so other small direct charges may exist.

How these numbers are made

Garbage: Marin Sanitary Service's San Anselmo residential flat rates effective January 1, 2026, adopted by the Town Council in Resolution 2025-4603 on November 10, 2025: $47.83 a month for a 20-gallon cart, $62.51 for 32, $125.13 for 64 and $187.69 for 96, each bundled with two organics carts and a recycling split cart, billed quarterly. Homes served by the small truck pay the higher ST rate.
Water: Marin Water rates effective July 1, 2026, for a single-family home with a 5/8-inch meter, billed every other month and halved to a month: ($55.61 service charge + $36.47 capital maintenance fee) / 2 = $46.04, and the bimonthly tier limits of 15, 25 and 80 units become 7.5, 12.5 and 40 units a month. The $0.66 per unit watershed management fee is added to each tier. Marin Water publishes no typical use, so the page starts at its default of 9 units a month.
Sewer: Ross Valley Sanitary District's single-family charge for the Ross Valley Rate Zone, $1,340 for 2026-27 (the Ordinance 102 maximum), counted with the property tax bill. We did not read a 2026-27 San Anselmo bill to confirm the amount billed.
Property tax: San Anselmo's seven tax rate areas (7-000 to 7-006) list identical rates in the County's 2025-26 rate book, so no one area is picked. Rates are the 2026-27 rates the Board of Supervisors adopted on August 25, 2026: 1% countywide, San Anselmo pension override 0.0590% and bonds 0.0040%, College of Marin bonds 0.0234%, Ross Valley School District bonds 0.0222%, Tamalpais Union bonds 0.0289% and Marin Healthcare District bonds 0.0185%, 1.1560% in all, less the $7,000 homeowners' exemption.
Flat charges on the bill (2026-27): Ross Valley School District parcel tax $1,282, Tamalpais Union parcel tax $560, Marin Wildfire tax at $0.1141 per square foot of building ($228.20 for 2,000 sq ft), Ross Valley Paramedic Authority tax $103.50 (Measure J: $94.50 plus up to $3 a year; this is the same tax as on Larkspur's 2026-27 bills, not a San Anselmo bill we read), Marin Water fire flow fee $75, Marin Emergency Radio Authority $29, SF Bay Restoration $12 and mosquito and vector control $12 (the district's 2025-26 report rate). The Ross Valley storm drainage fee is left out because San Anselmo voters chose in March 2024 to withdraw the Town from Flood Zone 9 (we could not confirm how the county bills it now). Seniors who file can be exempt from the Tamalpais Union parcel tax; we did not find the Ross Valley School District's senior exemption terms.
The starting home value is the Census ACS 2020-2024 median market value of owner-occupied homes ($1,576,700); under Prop 13 an owner who bought years ago has a lower assessed value and pays much less. Enter the net value from your tax bill.
Electricity and gas: same PG&E E-1 with MCE Light Green and G-1 construction as the neighboring Larkspur page, using baseline territory X (our reading: San Anselmo is not in the territory T described by named boundaries on the Mill Valley side of the county): $0.37292 per kWh up to the baseline and $0.45433 above it, plus PG&E's $0.79343 a day base services charge ($24.13 a month); gas $2.42480 and $2.92792 per therm plus the $0.12103 public purpose surcharge. Typical use is PG&E's 2024 residential average (EIA, about 500 kWh a month) and California's 2024 residential gas average (about 32 therms a month). Insurance is the 2022 California average homeowners premium (NAIC via the Insurance Information Institute).
