Plaza One 89: A Mixed-Income Apartment Community in Downtown Columbia

What Plaza One 89 offers

Plaza One 89 is a mixed-income residential building located at 89 Assembly Street in downtown Columbia, South Carolina. The property combines market-rate and deed-restricted affordable units in a single structure, meaning renters with different income levels live in the same building rather than in separate complexes. The building sits in the heart of Columbia's central business district, within walking distance of the State House, local restaurants, shops, and the Congaree River.

The apartments range from studios to two-bedroom floor plans. Units include modern finishes, climate control, and access to shared building amenities. Because Plaza One 89 operates as a mixed-income community, some units rent at market rates while others are reserved for households earning below the area median income, though the exact income thresholds and rent levels change based on funding and local housing policy.

Key Takeaways

• Plaza One 89 is located at 89 Assembly Street in downtown Columbia and contains both market-rate and affordable units in the same building.
• The building offers studios and one- and two-bedroom apartments with modern amenities and shared community spaces.
• Some units are deed-restricted for households below the area median income, though income limits and rent amounts vary by unit and funding source.

Location and neighborhood context

Assembly Street is one of Columbia's primary downtown corridors, and Plaza One 89's position there places residents near government offices, cultural institutions, and dining options. The Congaree River is accessible by foot, and the building sits within the walkable downtown core where many residents can reach work, shopping, and recreation without a car.

The neighborhood has seen significant investment and development over the past decade. Mixed-income housing like Plaza One 89 is part of Columbia's broader strategy to keep downtown residential, to serve workers at various income levels, and to prevent displacement as the area becomes more desirable. Living downtown means shorter commutes for some workers and access to urban amenities, though it also means higher noise levels and less green space than suburban or residential neighborhoods.

Unit types and amenities

Plaza One 89 offers studio, one-bedroom, and two-bedroom floor plans. The exact square footage, layout, and finishes vary by unit type and lease date. All units include heating and air conditioning, and the building provides common areas such as lobbies, hallways, and in some cases fitness or community rooms, though the specific amenities available should be confirmed directly with the property.

Parking at downtown Columbia apartments is often limited or available for an additional monthly fee, so prospective renters should ask about parking options and costs before signing a lease. Some residents rely on street parking, paid lots, or public transit instead of reserved spaces.

Affordable units and income requirements

The affordable units at Plaza One 89 are restricted by deed to serve households below a certain income threshold. That threshold is typically set at 60% or 80% of the area median income, depending on the funding source and the specific unit. Area median income in the Columbia metropolitan area changes annually and varies by household size, so a household of two may have a different income limit than a household of four.

Renters interested in an affordable unit should contact the property management office at Plaza One 89 or reach out to the City of Columbia's Housing and Community Development department. They can provide the current income limits, available units, and the process for renting an affordable apartment. Availability changes frequently, and some affordable units may have waiting lists.

How to inquire about units

Prospective renters can visit the building in person at 89 Assembly Street or call the property management office for information about current openings, lease terms, and move-in costs. The property manager can answer questions about specific floor plans, utilities included in rent, and lease length options.

For information about affordable units specifically, the City of Columbia's Housing and Community Development department can direct you to current programs and income thresholds. You can also contact local nonprofits focused on housing, such as the Columbia Housing Authority or community development corporations, which sometimes maintain lists of affordable properties and can explain the process.

Downtown living considerations

Living in downtown Columbia offers walkability and proximity to work and entertainment, but it also comes with trade-offs. Noise from traffic, nearby bars, and events is common. Parking can be expensive or scarce. Property taxes and utilities may be higher than in suburban areas. On the other hand, residents save on transportation costs, have access to public transit options, and can participate more easily in downtown cultural and civic life.

Before signing a lease, visit the building and neighborhood at different times of day and night to get a sense of the environment. Talk to current residents if possible. Ask the property manager about noise policies, security measures, and what utilities are included in the rent.

Frequently Asked Questions

How do I know if I meet the income limit for an affordable unit?

Income limits are based on household size and the area median income for the Columbia metropolitan area, which is updated each year. The property manager or the City of Columbia's Housing and Community Development department can tell you the current limit for your household size and help you understand whether your income qualifies. You will likely need to provide recent pay stubs or tax returns as proof.

What utilities are included in the rent?

This varies by unit and lease. Some apartments include water and trash in the rent; others require tenants to pay those separately. Electricity, gas, and internet are typically the tenant's responsibility. Ask the property manager for a complete list of what is included before you sign.

Is there parking at Plaza One 89?

Parking availability and cost should be confirmed with the property management office. Downtown Columbia apartments often have limited parking, and some charge a separate monthly fee. Street parking may be available but is usually metered or restricted by time limits.

Can I visit the building before I apply?

Yes. You can visit 89 Assembly Street during business hours to see the lobby, common areas, and the neighborhood. The property manager can also show you a model unit or a vacant apartment if one is available. This is a good way to decide whether downtown living and the specific building suit your needs.

Who do I contact if I have questions about affordable housing programs?

The City of Columbia's Housing and Community Development department is the primary resource for information about affordable housing in the city.
