What Attracts Chipmunks to Your House?

Chipmunks are ground-dwelling rodents that dig multi-chambered burrows for shelter, food storage, and raising young, and they'll use almost any structure that offers the same protection a rock pile or fallen log would in the wild — a foundation, a retaining wall, a woodpile, the space under a porch or shed. Add a nearby food source, whether that's a bird feeder, pet food left outdoors, or garden produce, and the location becomes worth staying near. There's no distinct lure beyond that combination, and a chipmunk that's found a good burrow site will typically stay close to it as long as food remains nearby.
