Marin County building permits, September 28–October 4, 2026

Public notice. Marin County’s public data portal lists 101 building permits with an issue date from September 28, 2026, through October 4, 2026. The newest issue date in that set is October 4, 2026.

Of those 101 records, Residential leads with 98 rows and Commercial follows with 3. Those groups cover all 101. Residential work is about 97 percent of the week — a Marin-typical mix where household repairs, additions, and small residential projects dominate issued activity.

Three commercial permits are a small slice, but they still matter for town centers and employment sites from Novato through San Rafael to southern Marin. A commercial row clears a different inspection path than a kitchen remodel; both appear on the same county portal when the county is the issuer of record.

Marin County sits north of the Golden Gate with high housing costs and tight land use. Weekly permit counts are one of the few open signals that residential investment is still moving — seismic upgrades, additions, and fire-hardening work often hide inside a generic Residential type tag on the public file.

For neighbors in unincorporated Marin and county-reviewed projects, 101 issued rows with only three commercial tags say the week’s energy was on houses, not storefronts. That is a baseline, not a judgment about which town is “busy.”

Notice Nearby places this paper on /ca/marin. Compare later Filed Nearby pulls to see whether the commercial share rises above a handful of rows or residential continues to carry nearly the entire week.

Marin’s residential majority is not a surprise in a high-cost Bay Area county, but 98 residential versus 3 commercial is still a sharp split. If commercial rows climb in later weeks, that will show up clearly against this baseline.

Fire-hardening, soft-story, and addition work often hide inside a generic Residential type on county portals. This notice cannot invent those subtypes. It can say the county issued 101 permits in the window and almost all of them were residential.
