The Lot That Couldn't Be Built On

The Mistake Nobody Talks About

This is a scenario, not a documented case: it is the pattern the screen exists to catch.

Picture a buyer who closes on a lot, retains an architect, orders a survey and a geotech report, and carries the loan for months before the first red flag.

The red flag? A historic preservation overlay that the county website didn't clearly show. The lot was zoned R-2. Permitted uses included "single-family and duplex residential." Everything looked green.

But the overlay — buried in a supplemental zoning map that was not kept current online — required design review, materials approval, and a public hearing process that killed the economics of a spec build.

The lot was technically buildable. Economically, it was dead.

This Happens More Than You Think

Not every case is this severe — but the pattern is consistent:

1. Buyer checks basic zoning (use + density)
2. Buyer misses overlays, conditional requirements, or environmental constraints
3. Buyer discovers the problem after committing capital
4. Buyer either eats the loss or spends months and thousands more navigating the issue

The cost of discovery after closing runs from a minor variance to a complete project redesign or abandonment.

The 20-Second Alternative

Buildability™ scores nine factors before you spend a dollar — the same published methodology (currently v3) on every parcel:

• Terrain (20% default weight): Lot-scale ground slope, queried live per request
• Zoning (16% default weight): Dimensional standards on record (FAR, coverage, minimum lot); omitted when only a designation name is known
• Flood (16% default weight): Flood zone, SFHA designation, and share of the lot inside an SFHA
• Soil (12% default weight): Soil survey suitability rating, queried live per request
• Wildfire (12% default weight): Hazard potential at the parcel; omitted when unmapped
• Utilities (12% default weight): Proximity to power, water, and road access; omitted when unmapped
• Lot geometry (11% default weight): Lot shape regularity computed from the real parcel ring
• Seismic (regional context, no weight): Seismic hazard level, queried live per request
• Radon (regional context, no weight): County radon zone designation

A scenario like this one is exactly what a first-pass screen is for: the report puts the zoning designation and its source in front of you in 20 seconds, so the supplemental-map check happens before closing, not after. Overlay districts and hearing timelines aren't yet modeled in the score — that's what your municipal follow-up (which the report links) is for, and it's a short call instead of a surprise after closing.

What To Do Next

Before you commit capital on any lot, check the Buildability Score™ at buildability.us. Checking an address is free with no signup — every factor cited to its government source. The full report, which adds the parcel record, is $99.

The question isn't whether you can afford one credit for a report. The question is whether you can afford to skip it.
