How do I know if my patio is a dutiful place to put a barn owl box?

Over the weekend, our school's Roots and Shoots club built some barn owl boxes to sell. I would similar to to buy one, but I don't know what kind of environment they live surrounded by. Does anyone know from like personal experience?
Answers: "Habitat Open country, forest edges and clearings, cultivated areas, and cities...This nocturnal spirit of a bird frequents such places as belfries, deserted buildings, and hollow trees. It hunts its food -- almost entirely rodents -- in junk dumps, neglected cemeteries, run-down farm, and empty lots contained by large cities."

"Habitat: The Barn Owl's favorite habitat consists of an expand low-lying area, preferably below 750-ft. elevation, near an abundant vole population. Although the owl have an extensive range it is atypical higher within the mountains. Grasslands in areas of milder climates near old buildings or hollow trees for perch and nesting may support large concentrations. The owl also avoids areas next to low mean January temperature, densely forested and intensively cultivated areas."

If you get the barn owl box, here is some biddable info:
"Recommended Site Characteristics for Barn Owl Nest Box Placement:

At least 12 ha of contiguous, upright quality hunting habitat (pastures, hay field, fields that hold been unfarmed for at least 3 years, grassy marshlands) available in 1 km radius of the nest box site (about 5% of the land nouns within this radius). Within a 10 km radius an supplementary 100 ha of good hunting habitat for dispersing birds is preferable.
Several unprocessed nesting and roosting opportunities (e.g. hollow trees, old-fashioned barns, old bridges) inside 3 km radius.
Dense forest should not exceed 50% of the habitat in a 3 km radius, to reduce risk of Great Horned Owl predation.
Within 30 km of the Lake Erie shoreline, to benefit from moderating lake effect.
A low density of well-traveled covered roads (e.g. provincial highway, busy regional roads) within 1 km radius.
Rodenticides are unused in and around buildings and neighbouring orchards and fields.
A passable expectation that the amount of foraging habitat will not decline over the next 5 years.
Presence of corn crib or hay lofts on the plant, which may sustain rodent populations and provide foraging opportunities during stocky snowfall or prolonged periods of significant snow cover on ground.
Notes on Barn Owl Nest Box Placement:

Boxes should be located within or on farm structures (i.e. generous wooden barn, unused concrete silo, abandoned tobacco kilns) so that birds hold unrestricted, year-round access. Avoid erecting nesting boxes on trees or telephone posts due to large predation risks (unless providing a predator baffle).
Preferably there should be little human disturbance around the nest box, although barn owls will nest surrounded by barns being used for regular and routine sheep farm activities.
Boxes should be fastened on the outside or inside of fruit farm structures at least 6 metres (18 feet) rotten the ground, preferably with the entrance facing directly to the outside and towards hunting habitat.
If affixed to the inside of a barn, a 6" by 6" hole should be cut within the side of the barn and the nest box attached so that birds fly directly into the box from outside.
If a box is placed on the exterior face of an existing wooden barn, it should be fastened give or take a few 1 metre (3 feet) below the eave. This will give some protection from the weather but not interfere next to the birds coming and going. Place the box so that the nest exit faces towards hunting habitat."
Barn Owls live anywhere near are good trees and a food source. If you hold rats, mice, squirrels or chipmunks you have a great nouns for barn owls. If not then consiter buying one and giving it to a wildlife enterprise or a nature center
