East Altadena/Pasadena, unlike the Palisades and Brentwood and Santa Monica, banned modern remodels. Every single house is original from 1900-1920. 

There are zero new rebuilds, no white 2015 Cape Cods--they don't exist. My house was built in 1915. You can't rebuild the history of these places. Rebuilding is great, it will all eventually be rebuilt, but the charm can't be replaced by new construction.
