Can I split my lot in Royal Oak?

In the One-Family districts, only if the new lots match the surrounding comparison area. Section 770-21B(2) says a lot may not be divided for a new single-family dwelling unless each resulting lot equals or exceeds the width, depth, and area of the majority of the developed lots in the ordinance-defined area.

For an interior lot on a defined block, that comparison area is the same block. Where there is no defined block, the ordinance looks within 300 linear feet on both sides of the street, and corner lots use the lots at the same intersection (§ 770-21B(2)). So even a parcel that could yield two lots meeting the 6,000 square foot One-Family minimum (§ 770-34D) or 13,000 square foot Large Lot minimum (§ 770-35D) cannot split if the comparison-area lots are larger.

You would need the dimensions of the developed lots around you before knowing where you stand, and each new lot must still meet the district minimums for width, depth, and area. If your property is not in a One-Family district, ask the city which subdivision standards apply.

The analysis is parcel-specific, and the city applies it, not this page. Bring your survey and your block's lot dimensions to the planning division at 248-246-3280 before spending money on an application.
