Want to add a garage, run a home business or split a lot near San Bruno? Start by checking the Pacifica zoning map, since the zoning district decides the answer. This Pacifica guide covers: which office sets the rules for a lot, how to match a parcel to its district, and the questions that save a wasted trip.
The Pacifica zoning map: start here
Within municipal limits, the town or city normally writes the zoning code, so a lot in Pacifica answers to that map. Past the city line, around Daly City, the county may have its own zoning, or none at all; the county planning or zoning office can confirm. To find out which side of the line a parcel is on: ask whether the parcel near Millbrae is inside the boundary.
The viewer San Mateo County publishes
Your first stop is the San Mateo County parcel viewer; it covers every tax parcel from Burlingame to South San Francisco. If you're looking near Burlingame, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Burlingame, the parcel card usually lists the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
City limits and county records
Pacifica is part of San Mateo County, California, and the county assessor maps its lots. Closer to Daly City, City or town hall handles matters such as zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits toward Burlingame usually follows county rules, not municipal ones.
Zoning is only step one
Once zoning clears a project near Millbrae, a building permit is a separate step; health and road departments may weigh in on land near Colma.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Daly City, but coverage can be spotty out of town. A printout of the tract near Colma is a good backup.
What to ask before you buy
Have the parcel ID ready and describe the plan for the lot near San Bruno; ask what's allowed by right and what needs a permit. Also ask whether the lot near Daly City is a legal lot of record, since some older splits don't.
Finding a parcel's zoning district
Some planning offices post the city zoning map as a PDF; if you can't find it, ask staff for the district by parcel number for land near Daly City. Labels such as R-1, B-2 or AG aren't self-explanatory, so read the ordinance chapter for each; codes near Daly City may differ from the next town's.
Sections, lots and bearings
California uses the Public Land Survey System, so rural legal descriptions near Millbrae cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Millbrae vary in size. Write down the legal description for the tract near Millbrae when you talk to a surveyor.
Before you lean on the lines
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real boundary on land around Millbrae. With a lot near Burlingame, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Rules tied to a district
For acreage around South San Francisco, each district lists what's allowed outright and what needs approval. Around Burlingame, overlay districts, whether historic, floodplain or corridor, may apply even when the base zoning looks simple.
Getting your bearings
Redwood City holds the county offices, where most land records are kept. You'll also find San Bruno, Millbrae, Colma, and Daly City, where town lots give way to larger tracts. About 726,353 people live in San Mateo County (Census estimate, 2023) across roughly 449 square miles. Landmarks such as Don Edwards San Francisco Bay National Wildlife Refuge help you orient on the aerial around Daly City.
Changing what's allowed
Near South San Francisco, most of these involve time, so budget weeks or months before you close.
Where the recorded documents are
For anything that matters, pull the recorded deed from the County Recorder; the parcel map near Millbrae only summarizes it. Long-held tracts around Burlingame can trace back through a long string of deeds, so a title company can sort it out before a purchase.
