Permitted uses, buildings, and other structures are listed in the Land Use Table in OHMC 15.10.040.

1. Area Per Dwelling Unit and Lot Dimensions. The minimum land area or lot size per dwelling shall be 15,000 square feet and the minimum width of the lot at the front building line shall be 100 feet. However, this shall not apply to prevent the construction of a one-family dwelling on a lot existing prior to the date of the enactment of this Zoning title.
2. Front Yards. No building, or part of a building other than steps, open porches, eaves and cornices and similar fixtures shall extend nearer the front street line (right-of-way line) than the average distance of setback of the nearest main building with 100 feet on each side of such building and fronting the same side of the street. When only one building exists on the same side of the street with the building to be erected and within 100 feet thereof, the building setback from the street line shall be not less than the setback of the existing building and twenty-five feet. When no building exists on the same side of the street with the building to be erected and within 100 feet thereof, the setback at the front shall be twenty-five feet from the side line of the street. However, the above shall not apply to require placing a building more than ten feet back of the front main wall of an existing adjacent building within 100 feet thereof. Building setbacks specifically established by OHMC 15.40.040 or by any other action of Council shall take precedence over the above.
3. Rear Yards. There shall be a rear yard with a depth of not less than twenty-five feet. When a building or property extends through a block from street to street, the front yard requirements shall be observed on both streets. On corner lots, the rear yard shall be not less than ten feet.
4. Side Yards. There shall be two side yards with a total width of not less than thirty feet, with a minimum side yard of eight feet. For a nonresidential building other than a garage or other accessory building, there shall be two side yards with a total width of not less than sixty feet, and for each foot the height of such building exceeds thirty-five feet, the total width of the two side yards shall be increased by four feet. The width of the narrower of the two side yards shall not be less than one-third of the total width of the two side yards.
5. Corner Lots. In the case of a corner lot, both yards abutting streets shall be determined as provided in Part B hereof. The minimum width of the lot at the building line parallel to the street considered to be the front street shall be 110 feet.
6. Height. No dwelling shall exceed two and one-half stories or thirty feet in height.
