Oakland County itself does not regulate building setbacks — the Michigan Zoning Enabling Act (MCL 125.3101 et seq.) delegates all front, side, and rear yard requirements to the county's 62 cities, villages, and charter townships. Typical single-family setbacks in Detroit-Pontiac suburbs like Royal Oak, Troy, Farmington Hills, and Bloomfield Township are 25–40 ft front, 5–16 ft side, and 25–40 ft rear. Royal Oak's One-Family Residential district (§ 770-34) requires the greater of 25 ft or the average of adjacent dwellings (not to exceed 50 ft) at the front, 5 ft side, and 35 ft rear. Bloomfield Township's R-1, R-2, and R-3 districts require 40 ft front, 16 ft each side, and 35 ft rear. Accessory structures such as detached garages and sheds typically must sit at least 5 ft from side and rear lot lines and 10 ft from the principal dwelling. Setback violations are addressed by the local building or planning department, with relief available only by Zoning Board of Appeals variance.
City of Royal Oak Code of Ordinances Part II, Chapter 770, Article IV, § 770-34 One-Family Residential
All required front yard setback lines shall be the minimum perpendicular distance measured from the right-of-way of the road upon which a lot or parcel fronts to the nearest point of the principal structure. Unenclosed porches and steps may extend from the face of the building into a required front yard setback a distance not more than seven feet, and shall not exceed one story in height. Chimn...
Building height limits in Oakland County are set by each municipality, not the county. In Royal Oak's One-Family Residential district (§ 770-34), no principal building may exceed 30 ft in height, and the same 30 ft cap applies in the One-Family Large Lot Residential district (§ 770-35). Most other Oakland County suburbs (Troy, Farmington Hills, Bloomfield Hills, Madison Heights, Birmingham) use a comparable 30–35 ft ceiling for detached single-family homes and allow 2 to 2.5 stories. Detached accessory structures — garages, sheds, pool houses — are typically capped at 15 ft and one story. Architectural features such as chimneys, antennas, water tanks, church spires, and elevator penthouses are exempt from the maximum height but must not exceed certain projection limits. Height is generally measured from average grade at the front of the building to the midpoint of the highest gable roof, or to the deck of a flat roof.
City of Royal Oak Code of Ordinances Part II, Chapter 770, Article IV, § 770-35 One-Family Large Lot Residential
No principal building shall exceed a height of 30 feet. All principal buildings shall be set back the greater of 25 feet or the average setback of adjacent dwellings, but shall not exceed 50 feet from the front property line. All principal buildings shall be set back no less than five feet from the side property line. All principal buildings shall be set back no less than 35 feet from the rear ...
Lot coverage — the percentage of a lot that may be covered by buildings and impervious surface — is regulated by each Oakland County municipality, not the county. Typical single-family district lot coverage maximums in Detroit-Pontiac suburbs are 25–35 percent of total lot area for principal and accessory buildings combined. Larger-lot communities like Bloomfield Hills and Bloomfield Township use lower caps reflecting the rural character (often 15–25 percent), while denser inner-ring suburbs like Royal Oak, Ferndale, and Madison Heights typically allow 30–35 percent. Most communities separately limit accessory building coverage in the rear yard (commonly 25–30 percent of the rear yard). Driveways, patios, and pool decks are usually treated as impervious coverage subject to the same or a similar cap. Exceeding the cap requires a Zoning Board of Appeals variance under MCL 125.3604.
