Gridics PropZone Alternative: Plotzy vs PropZone for Site Selection (2026)

Gridics PropZone is the closest tool to Plotzy on the zoning side: both attach development allowances to parcels so you can screen sites by what the code permits. They differ in coverage, in what surrounds the zoning data, and in how they are sold. This page sets the two side by side for developers, investors, and brokers doing site selection. We build Plotzy, so we have flagged where PropZone is the stronger choice.

The short answer

Choose PropZone if you work in a city Gridics has fully modeled and you want 3D zoning envelopes, development-capacity math, and a collaborative project workspace. Choose Plotzy if you work across many markets, want nationwide parcel coverage with zoning on every parcel, and need the owner's contact information in the same workflow at a published price.

What Gridics PropZone is

Gridics is a Miami-based zoning technology company. Its CodeHub platform hosts and models zoning codes for municipalities that contract with it, and PropZone is the site selection and research product built on that work: parcel filters, parcel-level zoning and development-allowance data (including 3D zoning envelopes where modeled), owner information, prior transactions, a proprietary redevelopment-opportunity score, and project workflow tools for teams. The company cites CBRE, KW Commercial, and RE/MAX among its users.

What it costs

Gridics does not publish PropZone pricing; the site directs you to a demo. Users have reported an entry-level plan around $50 a month, with higher tiers for more markets and features. Confirm current pricing with Gridics before comparing, because the number you are quoted depends on the markets you need.

Where PropZone is the better choice

• Modeled cities. Where Gridics has built the full 3D zoning model, PropZone can show buildable envelope, density, and capacity per parcel in a way no nationwide dataset matches. Coverage is deepest in the cities Gridics has contracted with, and Florida markets are well represented.
• Development capacity math. If your screen is "how many units can this parcel hold under current code", a modeled envelope answers it directly.
• Team workspaces. PropZone's project workflow and collaboration tools are built for firms working sites together.
• A low entry price for a single modeled market, if the reported entry tier still holds.

Where Plotzy is the better choice

• Coverage. 150M+ parcels across 3,200+ counties, each with a zoning category and the municipality's own designation. If you work several states, or a market Gridics has not modeled, Plotzy has the parcel and its zoning.
• Owner contacts in the workflow. Owner of record on every parcel plus an AI contact lookup that returns phone, email, and mailing address from public sources.
• Zoning AI. Instead of a modeled envelope, Plotzy reads the ordinance itself and answers permitted-use, setback, height, FAR, and parking questions with the section cited, for any parcel where the code is covered.
• Published, monthly pricing. Starter $180 a month, Production $300 a month, no annual contract, seven-day trial without a card. You can see the plan matrix on the pricing page before you talk to anyone.
• Layers and exports. Zoning and FEMA flood layers, custom GeoJSON and shapefile uploads, folders, notes, saved searches, and CSV export.

Side by side

Plotzy's limits, stated plainly

• No 3D zoning envelopes or development-capacity calculations. Zoning AI answers from the text of the code; it does not model massing.
• No redevelopment or opportunity scoring.
• Zoning AI is in beta and ordinance coverage is growing by municipality.
• Owner contact lookups are metered.
• Team collaboration features are on the Scale plan.

Other alternatives to consider

• Zoneomics for standardized zoning lookups and formal zoning reports; see our Zoneomics alternatives page.
• Deepblocks, TestFit, and Archiwise for feasibility and massing once you have a candidate site.
• The city's own zoning map and code, which is what every one of these products is built on; our zoning hub links the official sources for major cities.

How to decide

Pick five parcels you know well in each market you work. In PropZone, check whether the market is modeled and whether the capacity numbers match what your architect told you. In Plotzy, check the zoning designation, ask Zoning AI the two questions that usually kill your deals, and run the owner lookup. The tool that gets you to a correct answer and a phone number in the markets you actually work is the right one.

Frequently asked questions

How much does Gridics PropZone cost?

Gridics does not publish PropZone pricing; access is through a demo request. Users have reported an entry tier around $50 a month, with higher tiers for additional markets and features. Confirm with Gridics for a current quote.

Does PropZone cover every city?

No. PropZone's zoning and development-allowance data is deepest in municipalities Gridics has modeled through its CodeHub work. Coverage in other markets is thinner. Plotzy carries a zoning designation on every parcel nationwide but does not model 3D envelopes.

Which is better for a developer screening sites in several states?

A nationwide parcel platform with zoning on every parcel, such as Plotzy, because the screen works the same in every county. PropZone is stronger inside the specific cities it has modeled.

Does Plotzy calculate how many units I can build?

No. Zoning AI answers density, height, setback, FAR, and parking questions from the ordinance with citations; it does not run massing or capacity models. Use a feasibility tool or an architect for that step.

Can I try both?

Plotzy offers a seven-day free trial with no credit card. PropZone is demo-led; request one from Gridics.
