Zoning Slices
GIS layers that merge base and overlay districts into unique geometric combinations (“Slices”) to compute prevailing regulations — so you don’t have to.
Product specifications.
Structured GIS deliverables built for high-performance spatial queries and analysis workflows.
Zoning Slice
Every geometric intersection maps a discrete combination of base and overlay regulations.
Customizable Variables
Select from residential and nonresidential use permissions, ADU allowances, building heights, parking mandates, and minimum lot sizes.
Standard GIS Vector
File Geodatabase (.gdb), GeoJSON, and GeoPackage (.gpkg) formats ready for direct ingestion.
Built for your workflow.
Tailored zoning intelligence for the professionals who rely on it most.
Policy Research
Investigate trends around single-family prominence, missing middle housing, ADU adoption, and more.
Data Integration
Drop Zoning Slices directly into your data pipeline.
Geospatial Visualization
Display zoning regulatory outcomes as clean, non-overlapping polygons as you conduct internal analysis.
Scenario Planning
Model the impact of zoning proposals or decisions by comparing Slice outcomes before and after different scenarios.
Site Selection
Filter by the exact combination of zoning outcomes you need — permitted uses, minimum lot sizes, height caps — across any geography, at scale.

All You Need Is a Geography
Choose your geographic scope, select variable and license exactly what you require.
Zoning Slices reveal the land use regulations that apply to each unique combination of base and overlay districts, including permitted uses, dimensional requirements, lot characteristics, and more. You choose the geographies and regulations you need. We deliver the GIS layers.
1. Select Geographic Scope
2. Search Area
Type in the name of the jurisdiction (e.g., city, town, township, county) without typing in the state name. Then select the jurisdiction from the results.
3. Select Variables or Choose a Package
Select one or more use types to see their available variables. Each use type has its own set of data fields.
Choose a preset variable package
Or select use types
Every order includes all base variables listed in our Data Dictionary at no extra charge — the options below are additional, optional variables.
Why our data is the gold standard
Derived From Verified District Data
Each Slice is computed by flattening our verified base and overlay Zoning District data into non-overlapping polygons, so every Slice inherits the same sourcing rigor as our District-level data.
Human Verification
Our dataset is created, verified, and updated by human experts, not AI. Every entry undergoes a multi-step review process by team members with expertise spanning law, geography, planning, and data science.
Regular Update Cycles
Recognizing the value of refreshed zoning data, we continuously monitor, track, and input updates, and we regularly conduct full-state and full-metro area reviews.
Frequently asked questions
-
Any area shown on our coverage map, which is continually expanding.
-
Zoning Slices flatten the zoning map into a single non-overlapping layer. Wherever a base district and one or more overlays coincide, we merge them into one polygon (a Slice) and compute the prevailing regulations that actually govern that Slice. Zoning Districts, by contrast, tell you the rules for each zoning district in the selected geography, and provide the individual district polygon, with base and overlay districts provided separately. Zoning Districts show what each district requires or allows; Slices resolve differing regulations to show what governs a given geography.
-
Yes. At your option, Zoning Slices can carry a full slate of dimensional standards, including, but not limited to, floor area ratio, maximum height, lot coverage, minimum lot size, setbacks, and unit size requirements.
-
Unzoned land produces no Zoning Slice polygon, so it appears as a gap in the layer.
-
By email, as a geodatabase, GeoJSON, and GeoPackage.
-
Yes. Contact us to discuss pricing and delivery for larger geographies.
-
Embedding Zoning Slices in an internal tool or platform is permitted under our standard Data Licensing Agreement. Public-facing portals and subscriber-based portals fall outside of our standard agreement; if you're planning either, contact us and we'll discuss custom license terms.
-
Yes, as provided in our Data Licensing Agreement, including required attribution to Land Use Labs and safeguards against third-party downloads of the Zoning Slices themselves.
