Thinking about buying or selling property in Kalispell but not sure what you can build or how your plans fit local rules? You are not alone. Zoning and land use shape everything from home additions to short-term plans for a vacant lot. In this guide, you will learn how zoning works in the City of Kalispell and unincorporated Flathead County, what to check during a transaction, and where to confirm the details with official sources. Let’s dive in.
City or county: start here
Before you pull any rules, confirm if the property sits inside the City of Kalispell or in unincorporated Flathead County. Each has its own zoning map, code, and permit process.
- Inside city limits, the City of Kalispell Planning Department and City Council oversee zoning and planning. Start on the City of Kalispell website.
- In unincorporated areas, Flathead County Planning and Zoning administers county zoning and subdivision rules. Begin at the Flathead County website.
- Montana state law sets the framework for local planning and zoning, while cities and counties adopt the specific rules. For context, see the Montana legislative site.
How to verify jurisdiction
- Look up the address with the city or county to confirm city limits.
- Ask planning staff to verify the parcel’s zoning district and provide a zoning verification letter if needed.
- Use the official zoning map from the city or county to confirm the base district and any overlays.
What zoning districts mean
Zoning organizes land into districts, such as residential, mixed-use, commercial, industrial, or agricultural. Each district lists what is allowed and what may require special approval.
- Residential single-family: detached homes, accessory structures, minimum lot sizes, setbacks, and sometimes rules for ADUs.
- Multifamily: duplexes, townhomes, apartments, and different parking standards.
- Mixed-use and commercial: retail, office, and services along corridors and centers.
- Industrial or heavy commercial: warehousing and manufacturing, usually separated from housing.
- Agricultural and rural county zones: larger lots and lower residential density.
- Overlay districts: extra rules for areas like floodplains, historic districts, airports, or sensitive groundwater.
Names and allowed uses vary between city and county. Always pull the exact district standards from the city or county code.
What to check on any parcel
Before you make plans, check these core items in the governing zoning code:
- Permitted vs conditional uses for the district.
- Setbacks on all sides, plus maximum height and lot coverage.
- Minimum lot size and lot width.
- Parking requirements for the intended use.
- Landscaping and screening for commercial or multifamily.
- Overlay districts like floodplain, historic, or airport approach.
If anything is unclear, request written confirmation from planning staff.
Permits and approvals you may need
Projects often require more than one approval. The exact process depends on location, use, and site conditions.
- Building permits: Needed for most new construction, additions, and many remodels. Issued by the city inside city limits or by the county where applicable.
- Zoning approval and Certificate of Occupancy: Required before occupying a new use or structure.
- Conditional Use Permit (CUP): When a use is allowed only with conditions after public review.
- Variance: Relief from dimensional rules like setbacks when strict application creates hardship.
- Subdivision and platting: Dividing land into lots triggers subdivision review, infrastructure planning, and formal plat approval.
- Site plan review: Common for multifamily and nonresidential projects to review layout, access, parking, landscaping, drainage, and utilities.
- Floodplain, shoreline, or wetlands permits: Apply when near regulated waters or mapped flood zones.
Many approvals include public notice and hearings. Timelines and fees vary with project scope and infrastructure needs.
Buyer due diligence checklist
- Confirm jurisdiction and official zoning designation.
- Pull the zoning code text for your district and read allowed uses.
- Verify setbacks, height, lot coverage, and minimum lot size.
- Request building permit history and Certificates of Occupancy.
- Check FEMA flood maps and ask for elevation certificates if available via the FEMA Map Service Center.
- Confirm septic and well records with county environmental health for unincorporated properties.
- Ask about code violations, liens, or special assessments.
- Obtain HOA documents and CC&Rs if in a subdivision.
- Plan changes ahead. Ask planning staff if your intended use or addition is permitted, needs a CUP, or is unlikely under current rules.
Seller prep checklist
- Gather zoning confirmation and permit records.
- Address or disclose known code issues.
- Provide HOA, maintenance, and assessment documents.
- Consider a pre-listing zoning verification to answer common buyer questions.
Floodplains, wells, and other factors
Certain site conditions can change what is allowed, how you build, or what it costs to insure and maintain a property.
Floodplains and shorelines
Flood hazards are part of life near rivers, creeks, and lakes in Flathead County. If a property is in a Special Flood Hazard Area on FEMA Flood Insurance Rate Maps, expect elevation standards, limits on fill, and possible flood insurance requirements. Confirm zones and request elevation data through the FEMA Map Service Center and your local floodplain administrator.
Septic systems and wells
Unincorporated properties often use private wells and septic systems. County health or environmental departments regulate septic permits, setbacks, and drainfield suitability. In sensitive groundwater or source water protection areas, added storage and use limits may apply.
Environmental and habitat
Wetlands, steep slopes, and wildlife habitat can trigger added reviews or state and federal permits, including wetland rules under the Clean Water Act. Parcels next to public lands or conservation easements may carry limits on use.
Historic and design review
Designated historic districts or landmarks within the city may require design review for exterior changes. Always check with city planning if you are considering exterior work on an older property in a mapped historic area.
Roads, access, and frontage
New development and many remodels must address street frontage, sidewalks, and drainage. If access connects to a state highway, the Montana Department of Transportation reviews driveway location and sight distance.
Nonconforming uses and structures
A property may be legal nonconforming if it predates current rules. These uses or structures can often continue but have limits on expansion or rebuilding. Ask planning staff to confirm status in writing.
HOAs, covenants, and private rules
Private covenants and HOA rules are separate from zoning and can be more restrictive. Review the title report, recorded CC&Rs, and HOA documents during your contingency period.
Taxes, assessments, and districts
Local improvement districts and special assessments can add ongoing costs for infrastructure. Review county tax records and ask about any pending assessments.
Utility service
City parcels usually have municipal water and sewer. Many county parcels rely on wells and septic. Service availability and capacity affect project feasibility and hookup fees.
Planning your project timeline
Use this simple plan to reduce surprises and keep your project on track:
- Confirm city or county jurisdiction and zoning district.
- Read the district standards for use, setbacks, and height.
- Map constraints like floodplain, wetlands, or historic status.
- Verify utilities, or septic and well feasibility.
- Schedule a pre-application call with planning staff to discuss your concept and approvals needed.
- Build in time for public notice if a CUP, variance, or subdivision is required.
- Coordinate building permits and final inspections, then obtain a Certificate of Occupancy before use.
