Buildable takeaway
Full-lot buildable envelope appears supportive
Confidence
Medium
Best next step
Confirm the frontage line, measuring edge, and setback starting point with a current survey or plot plan.
Full-lot buildable envelope
10,200 sq ft
Deterministic envelope summary: The deterministic screen leaves about 10,200 sq ft in the full-lot buildable envelope.
Recommendation: Use this as an early deterministic screen only. The next spend should go toward verifying the key measured assumptions, not toward detailed design.
Read the full reportWhy this remains interesting
The full-lot buildable envelope supports multiple footprint-fit tests.
The frontage edge resolves cleanly enough to run a deterministic dimensional pass.
No trusted mapped hard constraints are currently clipping the full-lot envelope.
What could still change the answer
Front setback from the street edge is the main dimensional limit on the west side.
Final siting should still be checked against a current survey before reliance.
Mapped overlays and survey geometry should still be confirmed before design reliance.
