R-100 — One Family Residential (R-100)
Sterling Heights measures front and street-side setbacks from the centerline of the road, not from the lot line, using the Master Road Plan classification: local street 60 feet from centerline, collector 65 feet, secondary 73 feet, major 100 feet, regional 115 or 142 feet, cul-de-sac 80 to 90 feet by radius, freeway 40 feet from the right-of-way line, private road 30 feet from the easement line (Section 3.04.A.6.a). On a standard 60 foot local right-of-way that works out to 30 feet of yard behind the lot line. If the actual right-of-way is wider than planned, the setback becomes half the right-of-way plus 40 feet on major and regional roads or plus 30 feet on all others (Section 3.04.A.6.a).
Side: 10 feet on the least side (8 feet with a side-entry garage) and 25 feet total for both sides. A side-entry garage door must sit at least 22 feet from the side lot line (Section 3.04.A.6.b). Rear: 40 feet, reducible by 5 feet where the lot abuts a private open space at least 20 feet deep that is part of the development (Section 3.04.A.6.c, A.11).
Projections: eaves and chimneys may project 3 feet into the front yard, 5 feet into the rear, and 2 feet into the side; unenclosed porches may project 10 feet into the front yard and 15 feet into the rear; decks may project 15 feet into the rear yard subject to conditions (Section 28.10). Nothing over 30 inches tall may stand in the 25 foot corner sight triangle (Section 28.03).
