San Gabriel Valley Seismic Retrofit.

Bolt the house to the foundation, brace the cripple wall, add hold-downs. Earthquake Brace + Bolt (EBB) grant up to $3K.

The SGV is the fastest stretch of LA County we work in. Pasadena, Glendale, and Burbank all run their own building departments with shorter queues than LADBS. The catches are Pasadena's Landmark Districts and the separate municipal utilities — Burbank Water & Power, Glendale Water & Power, Pasadena Water & Power — each with their own connection fees and meter-set timelines.
