What Are GIS Maps & Why They Matter
Geographic Information System (GIS) maps are digital representations of physical land features linked to databases containing property-specific information. In Silver Bow County, these maps integrate spatial data—such as parcel shapes and locations—with tabular data like ownership, taxes, and zoning. This fusion enables precise, visual analysis of land use and property characteristics.
GIS maps matter because they replace outdated paper plat books and fragmented records with a single, searchable source of truth. They reduce errors in boundary disputes, streamline permit applications, and support fair property tax assessments. For investors, they reveal development potential. For homeowners, they clarify property rights and responsibilities.
What GIS Maps Include
Silver Bow County GIS maps contain multiple data layers that users can activate or hide based on their needs. Each layer corresponds to a specific category of land or property information. These layers are updated regularly to reflect new subdivisions, zoning changes, or ownership transfers.
The core layers include parcel boundaries, road centerlines, hydrology, topography, and aerial photography from 2020, 2022, and 2024. Additional thematic layers show flood zones, historic districts, tax increment financing areas, and utility easements. All data adheres to Montana State Library geospatial standards.
Parcel Boundaries and Legal Descriptions
Every parcel in Silver Bow County has a digitally mapped boundary derived from official survey plats and deed descriptions. These boundaries are accurate to within 1–2 feet using GPS-verified control points. Each parcel includes a legal description in metes and bounds or lot-and-block format, matching records filed with the County Clerk and Recorder.
Users can click any parcel to view its legal description, which includes township, range, section, and subdivision details. This information is essential for title searches, boundary agreements, and land use planning. Discrepancies between GIS boundaries and physical markers should be reported to the Surveyor’s Office for correction.
Lot Dimensions, Zoning, and Land Use Layers
GIS maps display exact lot dimensions, including frontage, depth, and total square footage or acreage. These measurements come from certified surveys and subdivision plats. Zoning classifications—such as R-1 (Single Family), C-2 (Commercial), or AG (Agricultural)—are shown as colored overlays with labels.
Land use layers categorize parcels by current use: residential, commercial, industrial, vacant, or public. This helps planners assess development patterns and enforce zoning compliance. For example, a parcel zoned R-1 but used as a short-term rental may trigger code enforcement action.
Property Ownership and Historical Records
Current property ownership is displayed for each parcel, including the owner’s name and mailing address. This data syncs daily with the Clerk and Recorder’s deed database. Historical ownership records are available through the “Deed History” tab, showing past owners, sale dates, and transaction amounts since 2000.
While GIS shows current owners, it does not include sensitive personal information like phone numbers or email addresses. For full deed documents, users must request copies from the Clerk and Recorder’s Office for $2 per page or view them online via the Montana Cadastral portal.
Assessed Value, Market Value, and Tax Data
Each parcel includes the most recent assessed value, market value estimate, and annual property tax amount. Assessed values are calculated by the Property Appraiser using mass appraisal models and updated every year based on sales data and inspections. Market values reflect recent comparable sales within the neighborhood.
Tax data shows the total levy rate (currently $1.28 per $100 of assessed value in 2024), breakdown by taxing jurisdiction (city, school district, county), and payment status. Users can view tax history for the past five years and download tax bills in PDF format directly from the parcel details panel.
How GIS Maps Help Property Owners, Investors, and Professionals
GIS maps empower users to make smarter decisions about land and property. Homeowners use them to verify lot lines before building fences or decks. Investors analyze zoning and vacancy rates to identify redevelopment opportunities. Professionals rely on them for due diligence, permitting, and litigation support.
The tool reduces reliance on third-party services and minimizes errors from outdated maps. It also promotes transparency in government operations by making assessment and zoning data publicly accessible. This builds trust between citizens and local officials.
Planning Renovations or Construction
Before starting any construction project, property owners should use GIS maps to confirm setback requirements, flood zone status, and utility easements. Overlaying zoning and building footprint layers helps visualize compliance with local codes. For example, a homeowner adding a garage must ensure it’s at least 5 feet from the side property line in R-1 zones.
Developers use the tool to assess site suitability for new projects. They can quickly identify parcels with sewer access, flat terrain, and commercial zoning—key factors in feasibility studies. The 2024 aerial imagery layer reveals existing structures, tree cover, and drainage patterns critical for site design.
Researching Property Value Trends
Investors and appraisers use GIS maps to track property value trends across neighborhoods. By comparing assessed values over time and overlaying sales data, they identify areas with rising demand or undervalued assets. The tool supports side-by-side parcel comparisons using the “Compare” feature.
For instance, a user might analyze all parcels in the East Ridge subdivision sold between 2022 and 2024. The average price per square foot increased from $185 to $210, indicating strong market growth. This insight guides bidding strategies and portfolio decisions.
Verifying Legal Boundaries and Easements
Boundary disputes are common in rural and historic areas of Silver Bow County. GIS maps provide a reliable reference point for resolving conflicts. Users can print a high-resolution parcel map with dimensions and legal description to share with neighbors or attorneys.
Easements for utilities, roads, or drainage are shown as dashed lines with labels indicating the holder (e.g., NorthWestern Energy or City of Butte). These easements restrict certain land uses and must be honored during construction. Ignoring them can lead to fines or forced removal of structures.
Downloading Property & Parcel Data in Silver Bow County
Silver Bow County allows users to download parcel data for offline analysis, reporting, or integration with other software. Downloads are free and available in several formats. The process is straightforward and requires only a few clicks within the Parcel Viewer interface.

Tips for Efficient Downloading and Filtering
For large areas, filter data before downloading to reduce file size. Use the “Filter” tool to select only residential parcels, parcels over 1 acre, or those with recent sales. This saves time and storage space. Avoid downloading the entire county unless necessary—full dataset exceeds 500 MB.
Schedule downloads during off-peak hours (before 8 AM or after 6 PM) for faster processing. The system limits concurrent downloads to three per user. If you need bulk data for research, contact the GIS Coordinator to request a custom export.

What You Can Find in Silver Bow County Parcel Data
Parcel data in Silver Bow County covers every aspect of land ownership and use. From basic lot size to complex tax levies, the dataset supports diverse applications. All information comes from official sources and is verified annually during the assessment cycle.
The data structure follows the Montana Cadastral Framework, ensuring compatibility with state and federal systems. Fields are standardized and documented in a public data dictionary available on the Property Appraiser’s website.
Property Ownership and Deed History
Each parcel record includes the current owner’s full name and mailing address. If the property is held in trust or by an LLC, the entity name appears instead. Ownership changes are reflected within 48 hours of deed recording at the Clerk and Recorder’s Office.
Deed history shows up to 10 past transactions, including sale price, date, and grantor/grantee names. This helps trace ownership chains and identify potential title issues. For example, a gap in ownership between 2015 and 2017 may indicate an unrecorded transfer requiring legal review.
Lot Dimensions, Zoning, and Land Use Details
Every parcel lists exact dimensions in feet or meters, total area in acres or square feet, and frontage along public roads. These values come from certified surveys and are used to calculate density and setback compliance. Irregularly shaped lots include multiple dimension lines for accuracy.
Zoning codes follow the Silver Bow County Unified Development Code. Each code links to a description of permitted uses, height limits, and parking requirements. Land use codes indicate current activity: residential, commercial, agricultural, or vacant. These codes influence tax rates and development potential.
Assessed Value, Market Value, and Tax Information
Assessed values are set annually on January 1 and published by March 15. They represent 100% of market value for residential properties and 95% for commercial, per Montana law. Market values are estimates based on recent sales of similar properties within the same neighborhood.
Tax information includes the total annual tax due, broken down by jurisdiction. In 2024, the average residential tax bill in Butte was $2,840. Users can view payment history, delinquency status, and exemption eligibility (e.g., senior or veteran discounts).
Easements, Rights-of-Way, and Special Districts
Easements are recorded rights allowing others to use part of a property for specific purposes. Common types include utility lines, driveway access, and drainage channels. GIS maps display these as labeled polygons or lines with the granting authority noted.
Rights-of-way refer to public road access corridors. They appear as shaded strips along streets and highways. Special districts—such as fire protection, water, or lighting districts—are shown with boundary lines and annual assessment amounts. Property owners in these districts pay additional fees for services.
