See what the site can carry
District rules, FAR, height, density, parking, and overlays load with the parcel so you know what is allowed before you commit capital.
Why DEV?
Model any parcel against live zoning, see massing and returns together, and leave with something you can share.
Massing and returns in one view
Live 3D sits beside the financial model. Change the scheme and watch buildable area and returns move together.
Export the analysis you built
Share a PDF of the feasibility and returns. The model you ran is the document your team reviews.
Monthly plans with included usage.
City counts estimate typical coverage. Additional usage is available as on-demand spending at the standard rate.

Short tutorials that walk you through the product, from first open to a finished workflow.
Product Overview
A walkthrough of DEV from first open to a finished site model. See how parcel selection, zoning, massing, and returns connect in one workspace.
Property Data
How parcel geometry, property records, and assumption sliders load for a site. Adjust inputs and watch constraints and yields respond before you build the scheme.
3D Model
View 3D massing alongside district rules, FAR, height, and overlays. Change the program and see the massing update beside the feasibility study.
Financial Returns
Model multifamily, condo, retail, office, hotel, and industrial scenarios. Returns move with the massing so you can test whether a site pencils.
Export Options
Share the analysis as a PDF or pull outputs for your team. The model you built becomes the document you send to partners and reviewers.
FAQ DEV
How the product works, what you can verify, and how usage is metered.
A typical first-pass feasibility study takes about five minutes. Once you select a parcel, DEV brings its property data, zoning, 3D massing, and financial analysis into one workflow so you can begin testing assumptions immediately.
Yes. DEV brings the parcel's district, permitted uses, FAR, height, setbacks, density, parking, and overlays into the property panel alongside your project. You can work from those values without reading the ordinance first.
Yes. Zoning comes from the city's ordinance and published maps, and each value includes a citation to its source. When a value is derived rather than stated directly, the Method view explains how it was determined.
Yes. Select multiple parcels and DEV will treat them as one site, combining their land and frontage. You can also draw a custom boundary for split parcels, ground leases, or land that is not yet accurately reflected in county records.
Yes. DEV provides local starting assumptions for rents, cap rate, hard and soft costs, contingency, and land price. Every input is editable, and the income, costs, and returns update as you make changes.
You can create a branded PDF with the property, zoning, demographic charts, assumptions, and returns. You can also export assumptions to CSV or share the project by link.
You can still select or draw a site, create a 3D massing, and use the financial model. DEV clearly indicates that zoning is unavailable until the city has been built.
Every data point comes from a Deepblocks or third-party service. Building and storing city data, and retrieving parcel information, all carry costs. Your subscription offsets those costs and includes an allowance at a subsidized rate. Additional usage becomes on-demand spending at the standard rate; DEV shows your usage and asks before incurring an on-demand charge.
