Nevada County runs from Gold Rush foothill towns up to Truckee near Lake Tahoe. My Neighborhood 2.0, the county’s map, links parcels to the recorded maps that created them.
My Neighborhood 2.0
The county’s GIS team rebuilt its My Neighborhood app as an Esri Experience app. A panel labeled Parcel Search and Recorded Maps holds six options: search by address, search by APN, search a list of APNs, search parcels by drawing a shape, and search recorded parcel maps or recorded subdivision maps. A feedback survey sits in the upper right.
The disclaimer says parcel boundaries on the site are not legal boundaries and directs users to the Recorder or Assessor for legal information. The app is linked from our California directory entry for Nevada County, and you can click the Sierra foothills on our county map.
APNs and recorded maps
California parcels use an assessor’s parcel number with book, page and parcel segments. The list search lets you paste several APNs at once, and the shape search selects every parcel inside an area you draw. The recorded map searches are the highlight, pulling up the parcel map or subdivision map that created a lot. Tips:
- Use the recorded subdivision map search to find the original tract map for a neighborhood.
- Parcel maps split land into four or fewer lots in California, so rural splits often have one.
- Paste a list of APNs when you are researching several lots at once.
How to find property lines in Nevada County
With recorded maps built in, the app does more of the work than most.
- Find the parcel and open the recorded parcel or subdivision map that created it.
- Get the deed from the Nevada County Clerk-Recorder.
- Look for monuments shown on the recorded map; foothill brush and pine needles can hide them.
- Hire a California licensed land surveyor for fences, additions or disputes.
Wildfire and defensible space
Much of the county lies in high fire hazard zones, and California requires defensible space around homes in those areas. Insurance availability has become a major issue for foothill buyers, so check fire hazard zoning and get insurance quotes early.
Gold Rush history and mining ground
Grass Valley and Nevada City grew around hard-rock and hydraulic mining, and old shafts, tailings and mining claims still affect some parcels. Mineral rights may be separate from surface ownership, so review the title report on rural land.
Truckee and the high country
Truckee sits on the east side of the county near Donner Lake, with snow loads and building rules very different from the foothills. The town handles its own planning, and short-term rental rules there change often.
Nevada County plat book
No bound atlas is sold for the county as far as we know. What makes up for it is unusual: My Neighborhood 2.0 can pull recorded parcel maps and subdivision maps directly, so the drawings surveyors use are a few clicks away.
Acreage and hunting land
Tahoe National Forest and BLM land offer public hunting, while private acreage around North San Juan and Rough and Ready shows owner and size on click. California Department of Fish and Wildlife sets seasons.
Proposition 13 and supplemental bills
Under Proposition 13, a purchase sets the base value, and yearly increases are capped at 2 percent until the next change in ownership. After closing, the Assessor typically sends a supplemental tax bill covering the difference between the old and new values for the rest of the fiscal year. That surprise bill catches many buyers off guard, so budget for it.
Proposition 19 lets eligible owners who are 55 or older, disabled, or wildfire victims move their base value to a replacement home anywhere in California. Retirees moving to Grass Valley or Penn Valley often use it. Inheritances changed too, with parent-to-child transfers now limited mostly to family homes the heirs live in. Ask the Assessor’s office about forms and deadlines.
Outside the towns, most foothill homes rely on wells and septic systems, and some draw irrigation water from Nevada Irrigation District canals. Well yields in hard rock vary a lot from one lot to the next, so a flow test is worth ordering before you buy. Septic designs on steep or rocky lots can be costly, and the county’s environmental health office reviews them. In the Truckee area, snow removal and wood stove rules add their own costs.
Is the Nevada County GIS map accurate?
The county says parcel lines on the site are not legal boundaries. The recorded maps in the app are the better reference, and a survey is the final answer. See assessor maps versus surveys.

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.
