Zero-lot line homes are built to the edge of the property boundary on one or more sides, creating more interior space from smaller lots. This design is popular in high-density areas and more affordable housing. Shared walls with neighbors reduce exterior maintenance costs. Requires careful planning for drainage, privacy, and access. Setback requirements, easements, and neighbor proximity affect design and livability. Zero-lot line homes appeal to buyers seeking affordability and smaller yards. Financing and insurance must address shared wall liability. Resale can be limited as some buyers prefer detached homes with private yards.
Pro Tip
Understand HOA responsibilities and shared wall maintenance before purchasing.
