Renting is the norm here
Renter-occupied homes make up 55% of occupied homes in ZCTA 57104, a far higher share than across South Dakota. Housing units in buildings with twenty or more units, and in buildings with five to nineteen units, are each a larger share than statewide. Points to raise with the property manager ahead of any order:
- Is CenturyLink fiber already wired into the building, and if not, does the owner know whether it can be brought in?
- Does a tenant order for the unit directly, or does the owner need to approve it?
- Which wall or closet holds the connection point in my unit?
- Are other providers wired into the building?

Older buildings add a second set of questions
Close to half the housing stock is older in this ZCTA: 48% of housing units in ZCTA 57104 were built before 1960, far higher than the South Dakota share. In an older building or house, ask the installer to point out the line's entry spot, to say whether outside work or new inside cabling is planned, and to suggest a router spot in the unit.
Comparing with a nearby ZIP
Single-family detached homes make up 94% of housing units in nearby ZCTA 57055, a much higher share than in ZCTA 57104.

Tenant questions for 57104 households
Can a tenant in a large 57104 building order CenturyLink directly?
Ask the property manager whether tenants order on their own or need the owner's approval, and whether the building sets rules on installation dates or access. Keep the reply in writing.
Why does the unit number matter when I check CenturyLink?
Enter the full unit designation in CenturyLink's tool, not only the building address. Then ask CenturyLink to confirm the result for that unit.
My 57104 building went up before 1960; what do I clear with the landlord first?
Get written approval from the landlord or property manager for any new cabling, wall openings or exterior mounting before the installer arrives. Then ask CenturyLink which of those steps your unit would need.

ZIP results are shortlist evidence, not address-level serviceability. National catalog plans are excluded until market eligibility is proven. Confirm service, the current offer, and installation terms at the exact address. See our full ranking methodology.
