Before you buy a lot near Moraga with a plan in mind, check the Pleasant Hill zoning map before anything else: a district label decides setbacks, lot size and uses. This Pleasant Hill guide covers: who controls zoning for a given parcel, how to match a parcel to its district, and when a variance or rezoning comes up.
The Pleasant Hill zoning map: start here
Inside town or city limits, the local government adopts its own zoning map, so property inside Pleasant Hill follows that code. Past the city line, around Orinda, the county's ordinance, if any, takes over; the county planning or zoning office can confirm. The quickest way to tell which applies: ask whether the parcel near Concord is inside the boundary.
The viewer Contra Costa County publishes
Property in and around Martinez appear on the Contra Costa County parcel viewer, a viewer that needs no account. Out toward Moraga, type a street address, an owner's name or a parcel number, and the matching parcel lights up. On ground around Moraga, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
What to ask before you buy
Have the parcel ID ready and describe the plan for the lot near Orinda; staff can point to the right section of the ordinance. Ask whether a parcel near Walnut Creek meets current minimum size, since some older splits don't.
Offices that can help
Deeds, mortgages and recorded plats for land near Orinda are with the County Recorder, sometimes only in person. Building or septic questions for a lot near Moraga go to planning, building or health offices, and the answer depends on jurisdiction.
City limits and county records
Pleasant Hill is part of Contra Costa County, California, so its parcels are on the county's map. Near Moraga, city or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the town limits near Walnut Creek often falls under county rules instead.
Where the recorded documents are
For anything that matters, get the recorded deed through the County Recorder; the parcel map near Walnut Creek only summarizes it. For land near Orinda, have ready the book and page shown in the record panel and the lookup takes minutes.
What the map can't tell you
Listed acreage is an estimate; only a licensed surveyor can set the real corners on land around Walnut Creek. On ground around Walnut Creek, records update in batches, so a deed recorded last month might lag behind.
Finding a parcel's zoning district
Start by finding the parcel on the Contra Costa County parcel viewer, copy its parcel ID, then compare it to the zoning map from the office covering Pleasant Hill. For a home near Walnut Creek, labels such as R-1, B-2 or AG stand for residential, commercial or agricultural districts; the letters vary from place to place.
Zoning is only step one
Even when zoning allows a use near Walnut Creek, you still need building permits and inspections; septic or sewer and driveway access are often reviewed too.
When a parcel crosses a boundary
Contra Costa County borders Alameda County, Marin County, Sacramento County, San Francisco County, and San Joaquin County; every one of them runs a separate parcel map. Ground near Martinez that runs to the line may show up across two assessors' files, so look at the neighboring map before you assume the acreage. With a lot near Lafayette, our state page lists every neighboring county map for California.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Martinez, but coverage can be spotty out of town. A screenshot of the parcel near Moraga with its ID helps when you meet an owner or agent.
Rules tied to a district
Near Lafayette, each district lists what's allowed outright and what needs approval. On ground around Orinda, overlay districts, whether historic, floodplain or corridor, may apply even when the base zoning looks simple.
Asking for an exception
Near Moraga, most of these involve time, so budget weeks or months before you close.
Getting your bearings
Martinez serves as the county seat, which is where the courthouse records live. Other places on the map include Walnut Creek, Concord, and Lafayette, each with its own cluster of lots. Around 1,155,025 people call Contra Costa County home (Census estimate, 2023) on about 717 square miles. Features like Clayton-Marsh Creek-Greenville Fault, San Pablo Dam Reservoir, and Mount Diablo State Park help you orient on the aerial around Walnut Creek.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
