Zero lot line is a feature commonly associated with which type of development?

• A. Conventional subdivisions
• B. Industrial parks
• C. Planned Unit Developments
• D. Rural farmland

Answer: (C)

Zero-lot-line development means building a home directly up to one or more property lines, with little or no side yard and often shared walls with a neighboring unit. This approach is used to pack more housing onto a site while still providing common areas and flexibility in layout.

Planned Unit Developments are designed to optimize land use and can mix housing types with fewer traditional setbacks. They allow this kind of dense, connected layout by using zoning flexibility, covenants, and homeowners associations to manage shared walls and common spaces. That’s why zero-lot-line living is most closely associated with a Planned Unit Development.

Traditional conventional subdivisions typically impose standard setbacks around each lot, leaving space between homes. Industrial parks are non-residential and focus on factories and offices rather than homes. Rural farmland involves expansive lots with minimal housing density.
