A new property owner discovered their purchased shop, previously a juice bar for 12 years, is zoned as a 'professional office' in an R1 residential area, preventing them from opening a cafe. A neighbour has reportedly complained for years. The advice suggests the previous owner may have operated illegally and that converting to a cafe is likely not permissible in an R1 zone, advising caution and verification with authorities rather than relying on past usage.
