Surprise communities Scott covers
Surprise was founded in 1938 by Flora Mae Statler and incorporated in 1960. Today it covers about 110 square miles. Scott covers all of it, including:
- Original Town Site: about one square mile along Grand Avenue, the city's original neighborhood.
- Sun City Grand: an active adult community built by Del Webb from 1996 to 2005, with four golf courses. Unlike Sun City and Sun City West, it's inside Surprise city limits.
- Surprise City Center: about a square mile around City Hall, between Bell and Greenway roads, including the Surprise Recreation Campus, Surprise Stadium and Ottawa University Arizona.
- Marley Park: a master-planned community opened in 2005.
- Sierra Montaña: a community at the foot of the White Tank Mountains, west of Loop 303.
- Asante: a Lennar-led community near 163rd Avenue that's expected to pass 14,000 homes when complete.
- Prasada: the master-planned area at Loop 303 and Waddell Road, anchored by the Village at Prasada shopping center.
Surprise ZIP codes include 85374, 85378, 85379, 85387 and 85388. Scott also serves Sun City West, Peoria and the rest of the West Valley. See the Peoria page.
What Surprise homeowners call about
Surprise is a homeowner city: 79.1% of homes are owner-occupied, and about 22% of residents are 65 or older, according to the Census. It's also still building out, with new homes going up in Asante, Prasada and other northwest neighborhoods. That shapes the work:
- Rekeys after closing: on a new home, keys pass through builders, subcontractors and agents. A rekey changes the pins inside your existing locks so only your new keys work. More on rekeying and home locks.
- Part-year residents: if you leave for the summer or hand keys to a caretaker, a rekey before you go means only the keys you give out will work.
- Keypad and smart locks: a code you can change from a distance is handy for part-year homes and for family members who check on the house.
- Safes: opening a safe when the combination is lost or the keypad dies, replacing safe locks, and moving safes during a move. More on safe services.
A note for HOA communities
Sun City Grand and most of Surprise's master-planned communities have design guidelines for the outside of a home. Check yours before you pick a new finish or style for front-door hardware. A rekey changes only the inside of the lock, so it doesn't change how the door looks.

Surprise's largest employers include the Dysart Unified School District, the City of Surprise, Sun Health and retailers along Bell Road and Loop 303. Scott handles the work an office, shop, clinic or school needs:
