邸 refers to a grand residence or mansion, while 亭 (same reading) refers to a pavilion, inn, or restaurant name, and the two kanji have a similar shape that learners often mix up.
From Middle Chinese 邸 (teiX), meaning 'residence of a high official' or 'mansion'. The honorific usage in Japanese developed naturally from this elevated sense.
principal residence; main house
