Types of Apartment Buildings

Low-Rise Apartment Buildings

These buildings are generally 1-4 stories high and may feature a small number of units. They often lack elevators.

Mid-Rise Apartment Buildings

Mid-rise structures are typically 5-9 stories tall and frequently include elevators and additional amenities.

High-Rise Apartment Buildings

High-rises are tower blocks that exceed nine stories and include sophisticated amenities such as elevators, security systems, recreational facilities, and sometimes even commercial spaces.

Depreciation Rules

In the context of United States tax code:

  • When 80% or more of the revenue is derived from residential rental units, the building may be depreciated over 27.5 years.
  • For buildings with less than 80% residential income or mixed-use (combining commercial and residential), the depreciation period extends to 39 years as for commercial property.

Applicability

Residential Use

Primarily, apartment buildings serve as residential homes for individuals and families. They provide housing solutions in urban areas where single-family homes may be less feasible.

Mixed-Use

Some apartment buildings incorporate commercial spaces, such as retail stores or offices, primarily at the ground level, to serve the convenience of the residents and the broader community.

Special Considerations

  • Zoning Laws: Compliance with local zoning laws is crucial. These laws dictate how land can be used and the types of structures that may be built.
  • Property Management: Effective management is essential for maintaining the condition of the building, ensuring tenant satisfaction, and maximizing financial returns.
  • Market Conditions: The demand for apartment units can fluctuate based on economic conditions, population trends, and demographics.

Historical Context

Apartment buildings have been part of urban development since ancient Rome, where “insulae” were multi-story apartment structures. In modern times, the rise of cities led to increased prominence of apartment buildings as a practical housing solution.

Examples

  • Trump Tower: A high-rise building in New York City with both residential and commercial units.
  • Marina City: A notable example of mixed-use apartment buildings in Chicago that contain apartments, shops, and a marina.

Comparison with Other Residential Properties

  • Single-Family Homes: Standalone buildings designed for one family, offering more privacy but requiring more maintenance.
  • Condominiums: Similar to apartments but typically owned by the residents, who are responsible for their units and share ownership of common areas.
  • Townhouses: Multi-floor homes that share walls with the next-door neighbors but have separate entrances.
  • Condominium (Condo): A type of residential unit owned by an individual within a multi-unit complex.
  • Cooperative Housing (Co-op): A collective ownership model where residents own shares in the corporation that owns the building.
  • Tenement: Historically, a multi-family renting building of lesser quality and amenities, now an older term still used in some contexts.
