How Old Is Geddes's Housing Stock?
With 94% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Geddes — it's the dominant profile. The median build year of 1902 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Geddes were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Geddes: Remediation Cost in Perspective
How does remediation fit within the broader financial picture for Geddes homeowners? The equity share is moderate — large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.
Remediation costs are moderate relative to home values in Geddes. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 33% below the South Dakota average.
Protecting Children from Lead in Geddes
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older interior plumbing shapes the local picture: 94% of Geddes homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
