Buildable envelope
The part of a lot left over once setbacks, easements, and corridors are removed.
Start with the parcel boundary, subtract every setback, then subtract every easement and right-of-way that prohibits structures. What remains is where a house, addition, pool, or shop can legally sit.
On irregular or corridor-crossed lots the envelope can be a small fraction of the recorded acreage.
Why it matters when you buy
Two lots of identical acreage can have wildly different envelopes, and only one may fit your plan.
