Allen FAQ
What is a sight visibility triangle in Allen?
A 25 ft x 25 ft triangle at corner lots where nothing between 30 inches and 8 feet tall is allowed, so drivers can see cross traffic.
Can I have a tree in my corner-lot front yard?
Yes, but canopies must be trimmed to 8 feet clear and trunks cannot obstruct sightlines. Low hedges and decorative walls are the usual problem.
Does the 30-inch rule apply to my driveway too?
Yes, a smaller 10-foot triangle applies at driveway approaches so vehicles backing out can see pedestrians and cyclists.
