Ms. Rhoda Chesterfield is a wealthy woman who lives directly under the Ross family's apartment. She used to be a fashion model for magazines where she was called a "Spring Chicken". She is the main antagonist of the series.
She owns a pet Chihuahua named Zeus, who she loves even more than her daughter. She doesn't like reptiles due to the fact that she has a phobia of them and because Mr. Kipling liked the taste of her. She even tried to have Mr. Kipling removed from the building after she found out he was living there; however, when a hawk tried to attack her Chihuahua, Mr. Kipling saved the dog's life by swatting the bird away with his tail. Afterward, she decided to allow Mr. Kipling to stay. She is cruel, bratty, spoiled, and mean at first, but somewhat softens and is nicer afterwards. Out of all the Ross children, she favours Emma, mainly because Emma annoyed her the least.
She hates large reptiles, such as Mr. Kipling. However, since Mr. Kipling saved her dog's life, she tolerates his presence.
She and her dog have cheat days, where they allow themselves to eat junk food. Ms. Chesterfield and Zeus usually binge (eat the food) together.
She thinks Zuri is very strange, and has called her a "strange little girl" multiple times.
She goes against Jessie´s idea of a Lemonade Stand in the lobby.
She flirts with Bertram and seems to have a crush on him but merely because he saved Zeus' life.
She hates Indian dragon fire peppers.
She has a habit of mispronouncing Jessie's name, names include "Bessie", "Nessie", "Essie", or "Tessie".
Not only does she mispronounce Jessie's name often but she also has a habit of mispronouncing other people's names such as, Darla, in Romancing the Crone. She called her, Marla. Although she may do it on purpose to annoy Jessie.
She wants Jessie to keep Zuri away from her as she seemed strange when Zuri tried to keep Ms. Chesterfield from finding Mr. Kipling.
