A four-story town house development could soon come to downtown Plano after city planning commissioners approved the plans on Tuesday. The Plano Planning and Zoning Commission gave its approval to a zoning change that would allow Texas InTown Homes to construct 49 town-house units on a 2-acre lot across the street from the city's municipal court building. The zoning change will require Plano City Council approval at a future meeting before the developer can begin construction. The housing concept would feature individual, attached town house units for sale, with each unit taking up four stories. Some of the first-floor spaces could be outfitted for retail or other commercial uses, a Texas InTown Homes representative told commissioners. The developer plans to add on-street public parking to H Avenue and additional visitor parking. The commission also approved a preliminary site plan and new development standards restricting the buildings to four stories in height. There was previously a five-story limit.
