Tucson FAQ
Does this apply to single-family homes?
Most shade and canopy ratios target commercial parking and streetscapes, not single homes, though native-plant preservation rules still apply.
Can I substitute shade structures for trees?
In some pedestrian zones awnings or canopies count, but UDC tree counts generally must still be met for stormwater and ecological benefits.
