UNDA Technology · Precedent and market intelligence for property
Every decision on a site has a reason. We index it.
Councils and counties publish their decisions. The reasoning sits in minutes, staff reports and scanned books that nobody searches. UNDA reads the public record and turns it into evidence you can bring to your next application.
See every approval. Each condition. Every precedent.

The problem
The decision is public. The reasoning is buried.
A register tells you a case was approved. It rarely tells you why, what the board asked for, or how the same request went next door. That context decides how you prepare.
Outcome and date
Case number, address, approved or denied. Useful, but it stops at the result.
Reasons and conditions
The board’s findings, votes and conditions, often in scanned PDFs going back decades.
What happened next
Recorded distances, permit timing and the work that was actually built.
One record, joined by parcel
We connect all three, so every precedent around a site can be read in one place.
How an application moves
Every project passes the same desks. Precedent helps at each one.
Wants to build
A house, an addition, a new building or a change of use.
Prepares the application
Plans, setbacks and the case for any variance or rezoning.
Argues it, where needed
Hearings, appeals and conditions negotiated with the authority.
Decides
Within the rules it’s a permit. Outside them it goes to a board or panel.
Apply with evidence. Bring the board the decisions it has already made on similar sites: what was approved, what was refused, and the conditions it set. Precedent, not prediction.
