McKinney is the seat of Collin County, with 195,308 residents in 2020 across about 68 square miles. Its mix of a historic square, golf-course neighborhoods and new construction means older wood, fresh landscaping and plenty of eaves for pests to use.
McKinney is the county seat of Collin County, at about 577 feet above sea level on 67.7 square miles. Its Historic Downtown centers on the square, the Old Collin County Courthouse and the 1911 Post Office, now home to the Collin County History Museum. Adriatica Village and the TPC Craig Ranch golf course are among newer landmarks.
The city recorded 72,876 housing units in 2020 and an average household size near 2.9. July highs average about 92.7 degrees, the record is 112, and rainfall averages about 41 inches a year, peaking in May at 5.68 inches. That spring moisture, plus older timber and newer lawns, makes wasps, mosquitoes, ants and termites a yearly routine.
