A townhouse is defined as a dwelling attached on one or both sides, in a row of three or more. Townhouses may be rental, condominium, co-op or freehold, but to qualify for the contest, the front garden must be cared for by the occupant. End units generally have larger gardens than middle units, but they are still classified as townhouse gardens.
Semi-detached houses are not classified as townhouses, even though they may sometimes have smaller gardens. They should be entered in the Large or Small Garden classes.
