Northridge is post-war tract and ranch housing on generous flat lots. It also gave its name to the 1994 earthquake, and the seismic performance of this housing stock is better documented than most.
What that means for building here
- Large lots make detached ADUs and substantial additions practical on most parcels.
- Some housing here was damaged and repaired after 1994, and the quality of those repairs varies, which is worth establishing before a major renovation.
- Slab-on-grade is common in the post-war tracts, so bolt-and-brace does not apply but slab-related foundation issues do.
- Summer heat drives insulation, glazing and HVAC decisions.
