High-rise Buildings
Similar to condominium communities, high-rise owners typically only own their unit and have a shared interest in the common area. High-rise communities have very specific needs & unique challenges.

Cardinal's Response Efforts to COVID-19

The Coronavirus pandemic has been stressful for us all. We’ve had to make a lot of changes and adapt to a whole new way of life. We’re pleased to hear from our community that our response to the pandemic has been felt in positive ways.
“The Cardinal Management response to COVID-19 has been exceptionally informative and professional.  I have attended each of the CMG tele-conferences and found them to be very useful.  The senior executives have demonstrated their sincere concern for the customers and their presentations have been excellent.”
"We at Hawthorne never received any guidance like what Cardinal has been issuing on a regular basis regarding the pandemic.  I am impressed with the level of content and the level of detail of the specific information regarding issues of direct interest of the HOAs. Frankly, I am extremely pleased that we have signed on with Cardinal."
“Our Property Manager has exhibited a great deal of leadership and flexibility when addressing the many issues and concerns that have transpired in our community during the COVID-19 pandemic.”
"What a great job Cardinal Management has done in issuing these COVID-19 updates. I think they've been super informative. I appreciate receiving the info both as a board member and a citizen. Very helpful, and I'm sure each update we've received took considerable time and attention to compile, especially under the circumstances. Many thanks for all the good work!"
“Thank you. You are amazing. We have never had such a tense topic that affected everyone and you maneuvered us through it.”
