Most Hayward homes are 1950s–1960s tract houses. The Hayward Hills have homes on steep lots. Many Hayward tract homes have been expanded with added rooms and bathrooms, and original copper plumbing, water heaters and drains are reaching the end of their life. Hillside homes sit on steep lots with retaining walls and drains that need upkeep, and some neighborhoods sit right on the fault line.
