Questions about this score
What is the Buildability Score™ for 3921 N PAULINA ST, CHICAGO, IL, 60613?
3921 N PAULINA ST, CHICAGO, IL, 60613 carries a Buildability Score of 90 out of 100 (grade A+). The score is composed from 6 weighted factors — each cited to its federal or jurisdictional source and re-runnable live on this page.
What does a grade A+ mean?
Grade A+ reads as a scored buildability read across zoning, flood, seismic, soil, radon, wildfire, and utility factors. The grade is derived from the numeric score (90/100) on the published Buildability™ scale.
Which factor most affects 3921 N PAULINA ST, CHICAGO, IL, 60613?
The weakest factor at this address is radon (scored 75). That's the factor most likely to constrain what a design can carry, and the one to inspect first before committing capital.
What's this parcel's strongest attribute?
Flood scores 95 out of 100 — the highest of the 6 factors read for this address.
Where does the data come from?
Every factor cites the federal or jurisdictional dataset it came from — FEMA (flood), USGS (seismic), USFS (wildfire), EPA (radon), USDA/NRCS (soil), and the local jurisdiction's own zoning record where available. Sources are queried live and re-run on refresh; the score cannot outrun its data.
Does the Buildability Score account for local zoning in Chicago, IL?
When Chicago, IL's zoning record is on our roster, the score reads the jurisdiction's own dimensional standards for the district this parcel sits in. When it isn't, the zoning factor drops out rather than being estimated — which is why parcels in un-rostered jurisdictions still return a score, just one that doesn't count zoning.
Is this an official determination?
No. The Buildability Score™ is a preliminary due-diligence read, not an entitlement or permit approval. Governing bodies retain sole authority over binding land-use decisions. The score's role is to make the diligence conversation faster and better-grounded, not to replace it.
