Grosvenor continued the family interest in horse racing and, when he was living in the country estate, he spent time hunting and fishing.
He gave generously to charity, and built and restored churches.
He was an early patron of the Chester architect John Douglas.
In 1865–66 Douglas designed St John's Church for him in his estate village of Aldford.
About the same time, Grosvenor gave fields in Chester to the city council for the formation of Grosvenor Park.
For this park Douglas designed a number of items, including the Entrance Lodge, the gates, and a cover for Billy Hobby's Well.
In 1865 the citizens of Chester began to raise money for the erection of a statue "to mark the public and private worth of his lordship, and the high estimation in which he is held by his neighbours and tenants, as well as by all classes of the community".
 Over £5,000 (equivalent to £480,000 as of 2019) was raised.
 The statue showing the marquess in his garter robes was designed by Thomas Thornycroft, and erected in 1869; it still stands in Grosvenor Park.

Grosvenor's parents had instilled "high moral principles" in their children, and these stayed with Richard throughout his life.
He has been described as "of austere character and unswerving devotion to duty as family man, politician and landlord".
His obituary in The Times says "he administered his vast estate with a combination of intelligence and generosity not often witnessed".
