What Are GIS Maps & Why They Matter

What GIS Maps Include

This comprehensive approach makes the platform a trusted resource for professionals and the public alike.

Parcel Boundaries and Legal Descriptions

Every parcel in San Bernardino County is defined by precise boundary lines and a legal description, typically using the Public Land Survey System (PLSS) or metes and bounds. The GIS maps display these boundaries as vector polygons, allowing users to see exact property lines. Legal descriptions appear in the attribute table when a parcel is selected, including township, range, section, and parcel identifiers. This information is essential for title searches, deed preparation, and resolving boundary conflicts. Surveyors and attorneys rely on this data to verify accuracy before conducting field work. The system also highlights discrepancies between recorded deeds and mapped boundaries, helping users identify potential issues early.

Lot Dimensions, Zoning, and Land Use Layers

San Bernardino County GIS maps include detailed lot dimensions such as frontage, depth, and total square footage. These measurements are derived from official surveys and recorded plat maps. Zoning classifications—like residential, commercial, agricultural, or industrial—are displayed as color-coded overlays. Each zone includes links to the relevant municipal code and development standards. Land use layers show current usage, such as single-family homes, vacant land, or public facilities. Users can compare zoning with actual use to identify non-conforming properties or potential redevelopment opportunities. This layering system helps planners, investors, and homeowners understand how land can be legally used and developed within the county.

Users can view grant deeds, quitclaim deeds, and easements directly from the map interface. This transparency supports due diligence for buyers, lenders, and real estate agents. It also helps identify inherited properties or unresolved ownership disputes.

Assessed Value, Market Value, and Tax Data

San Bernardino County GIS maps provide assessed values as determined by the County Assessor, which are used to calculate property taxes.

Users can view tax delinquency flags and special assessments like Mello-Roos or school bonds. The system updates assessed values annually, following California Proposition 13 guidelines. This information helps homeowners budget for taxes and investors evaluate return on investment. It also supports appeals processes if a property is over-assessed.

Users can measure distances from property lines to proposed structures, ensuring compliance with local codes. The system also shows flood zones, fire hazard areas, and protected habitats that may require permits. Contractors and architects use this data to create site plans and submit accurate applications.

Verifying Legal Boundaries and Easements
