Originally built in 1888 as two-story duplex apartments, and renovated in 2003, these untis are being redesigned and updated to achieve Passive House certification through a comprehensive Deep Energy Retrofit (DER) of the buildings' exterior envelopes.

Since January, we have seen shifts in immigration enforcement and an expanded use of worksite raids. Immigration enforcement affects workers and employers. During this Know Your Rights training with Organized Power in Numbers, employers will have the chance to understand their Constitutional rights if immigration comes to the workplace, learn about different kinds of immigration enforcement actions, and hear about practical steps employers can take to prepare.
