Field notes
The page separates apartments (30 years or older) from detached and multi-family low-rise homes (20 years or older), then compares the figures with rebuilding and redevelopment thresholds. Its source note names housing census data supplied through Seoul Data Hub, while redevelopment activity is compiled from press reports and Seoul announcements through October 2026. It cautions that district averages are approximate and that actual designation is assessed at block level.
