Setback

The minimum distance a building has to sit from a property line, road, or other feature. Local zoning sets the rules. Building inside a setback usually needs a variance.

Why a seller cares

Setbacks decide how close to a line anything can be built, and a structure inside one is a zoning violation a buyer's lender or a city inspection can catch. A shed or an addition too close to the line is a question at sale.

A simple example

Your detached garage sits four feet from the side line where the setback is five. The buyer's survey shows it, and the city is asked for a letter.

Setback: a simple example
What is foundWhat tends to follow
A structure inside the setback, built with a permitUsually fine; the permit is the answer
Built without a permitA variance, a letter from the city, or a disclosure the buyer accepts
Nothing inside the setbacksNothing to do

Setbacks are lines inside the lines, and the survey draws both.

What people get wrong

That setbacks only matter when building. They matter when selling, because the survey shows what was built.
