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.

National coverage for Zoning Slices

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.

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

Not sure if slices are the right fit?

We make five data products built for analyzing zoning, each designed for a different question, scale, and workflow.
