In seconds.
Lost in a maze of city websites?
Public records. Local requirements. Building codes. Live zoning data. We go directly to the source, then compile your property-specific details into one clear report. All in seconds, not weeks.
How much of the lot you could build on.
Not every part of your property can hold an addition.
How tall your home or addition can be.
Local rules decide the max height allowed on your property.
How level (or steep) your property really is.
Because looks flat and is flat aren’t always the same.
Your home is your biggest investment. But
most people only know what it is today, not
what it could become. That’s called build
potential. And it might actually be more
important than square footage. Because it
reveals how your property could grow, expand,
and increase in value over time.

research. We built
Underbuilt Radar to give

A property is underbuilt when the current structure is smaller than what local zoning and building codes allow on that lot. For example, if a home is 1,500 square feet but zoning permits up to 4,500 square feet, that property is underbuilt. The Underbuilt Score in Breezy shows how much development potential remains. This concept is most relevant in markets where land is scarce and expensive. If you're not familiar with it, that's normal. It's a newer negotiation tool.
A floor area ratio (FAR) limits how much total building is allowed relative to the lot size. If your lot is 10,000 square feet and the FAR is 0.45, you can build up to 4,500 square feet of structure. FAR is one of the zoning factors that determines a property's Underbuilt Score in Breezy.
A setback requirement is the minimum distance a building must be set back from the property line. Front setbacks, side setbacks, and rear setbacks are defined by local zoning codes. Setbacks reduce how much of a lot you can actually build on, which is why the maximum buildable size is often smaller than the raw lot dimensions suggest. Breezy factors setbacks into the Underbuilt Score calculation.
The Underbuilt Score is a percentage that represents how much of a lot's building potential is currently unused. A score of 70% means the existing structure uses only about 30% of what zoning allows. A higher score means more room to build. A score near 0% means the property is already close to its maximum allowable size. The score accounts for zoning codes, setbacks, height limits, floor area ratios, and terrain.
The colorful map overlay in the Underbuilt view shows the topography of the lot. It highlights flat vs. sloped areas. This matters because building codes factor in slope when calculating how much you can build. Properties on steep terrain have less buildable area than the lot size alone would suggest. Flat areas can generally be built on; steep slopes often cannot.
