Nov. 3 Parcel Taxes: What Bay Area Homeowners Need to Know

Why a Realtor is writing about a $129 tax

Nobody loses sleep over a parcel tax that costs about $129 a year. But parcel taxes show up in the tax bill a buyer pulls during due diligence, in escrow prorations at closing, and in the questions a careful buyer asks before writing an offer. Three are on the Nov. 3, 2026 ballot in my market, plus two transfer-tax measures that matter to a narrow group of sellers. Here is the plain-English version of each.

San Francisco Prop H: the Muni parcel tax

Prop H is a citizen initiative that would create a new parcel tax to fund Muni; it needs a simple majority to pass (GrowSF voter guide, read Sept. 27, 2026). For a single-family home, the tax is a flat $129 per year for homes up to 3,000 square feet, then $0.42 per square foot in the 3,000 to 5,000 square foot range, then $1.99 per square foot above 5,000 square feet with no cap (GrowSF Prop H guide, read Sept. 27, 2026). Multifamily buildings pay $249 per year up to 5,000 square feet, then $0.195 per square foot, capped at $50,000 (GrowSF, read Sept. 27, 2026).

Two details matter most to my clients: homeowners 65 and older who own a single-family home pay $0, and landlords of rent-controlled units can pass through at most $65 per unit per year (GrowSF, read Sept. 27, 2026). The tax would run 15 years, July 2027 through June 2042, and is expected to raise about $177 million per year (GrowSF voter guide, read Sept. 27, 2026; Local News Matters, SF Nov. 3, 2026 measures list). Tomorrow's post goes deeper on Prop H with worked examples.

Marin Measure P: 5 cents per square foot for child care

Across the bridge, Measure P (the Child Care Initiative) is a special parcel tax of 5 cents per building square foot: a 2,000 square foot home pays about $100 per year and a 3,000 square foot home about $150 (Marin County Elections, Measure P page). It would raise roughly $12.5 million per year over 15 years, needs a simple majority, allows an optional annual CPI adjustment and caps at 100,000 square feet per parcel (Marin County Elections, Measure P 11/03/26 page; Marin IJ, Sept. 25–26, 2026). One point worth knowing for older homeowners: opponents note there is no senior or low-income exemption in Measure P (Marin IJ, Sept. 25–26, 2026). That is a real difference from SF's Prop H.

Measure Z: a small one on the Tiburon Peninsula

Measure Z affects only Paradise Cay, the waterfront neighborhood on the Tiburon Peninsula. It would raise the existing dredging parcel tax from $1,900 to $2,200 per year, allow increases of up to 3 percent per year, and run 10 years, raising about $272,800 in the first year. Only 274 ballots go out for it (Marin IJ, Sept. 25, 2026). If you are buying or selling in Paradise Cay, this belongs in the disclosure conversation; it is far larger than the countywide measures.

Two other SF measures that touch sellers

Two other measures on the same ballot affect specific sellers. Prop I would dedicate half of transfer-tax revenue from sales over $10 million to affordable housing (Local News Matters, "San Francisco November 3, 2026"). It changes where the money goes, not what a seller pays. Prop J would add a transfer tax of 0.5 percent to 6 percent on foreclosed properties, estimated at $100 million to $150 million per year (Local News Matters, SF Nov. 3, 2026 measures). If you are buying or selling a foreclosure, read Prop J closely.

What this means if you are selling or inheriting a home

For a typical seller, a $129 or $150 per year tax will not move your sale price. It does show up in the escrow prorations, where buyer and seller split the year's property tax bill by closing date, and on the tax bill the buyer reads when running numbers. "What is this line item?" is a fair question, and knowing the answer keeps the deal smooth.

For families I work with in probate, parcel taxes are a small piece of a larger picture. When you inherit a home, the property tax question that matters most is Prop 19 reassessment, not a $129 parcel tax. But every recurring cost goes into the decision to keep, rent or sell, so read the special assessments line by line before the estate makes that call. Note the difference: Measure P has no senior exemption, so an heir who is 65 or older would still pay it in Marin, while the same heir living in a single-family home in San Francisco would owe nothing under Prop H.

Vote-by-mail ballots go out about 29 days before the election, so expect yours in early October. If you have questions about how this affects a home you own or are about to inherit in San Francisco or Marin County, reach out and I will walk through the tax bill with you.
