UNDA Technology · Every decision, in context
Every decision on a site has a reason. We index it.
Councils, counties and utilities publish thousands of decisions a year, but the reasons are buried in minutes, reports and dockets. UNDA reads them, links each one to its site, its conditions and what happened next, and turns them into evidence for the people who build, manage and power property.

1804 Cool Spring Dr., Alexandria · carport addition
One request · Mount Vernon, Fairfax County
One request, 15 decisions around it.
In 2025, 1804 Cool Spring Dr. asked to build a carport closer to the side line than the rules allow. Within half a mile, the Board had already decided 15 side-yard cases since 1996: 13 approved, 2 denied.
The ask: 6.0 ft from the line.
An R-3 lot of about 12,036 sq ft. The carport would sit 6.0 ft from the southeast side lot line. Would that be too close?
Where the neighbours landed.
Nearby approvals ran from 3.3 to 10.7 ft, and three were at exactly 6.0 ft. Both denials were carports right at the line: 1.4 ft and 0.2 ft. The 0.2 ft carport was later approved at 6.0 ft.
Approved 6–0, July 2025.
The Board found the carport in keeping with the neighbourhood, with no harm to the adjoining lot, and the minimum reduction needed. Each case turns on its own facts: precedent, not prediction.

The side-yard decisions around a lot.
Before 1804 Cool Spring Dr. asked to build a carport 6.0 ft from the line, the Board had already decided 15 side-yard cases nearby. UNDA puts them in front of you before you apply.
How close to the side line? →Guides and samples
Start with the question you have.
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.
Products
One public record. A product for each job.
Each product reads the same kind of source, the decisions public bodies publish, and organises it for the people who act on it.
