What are the rules for decks, patios, and gazebos in Rochester Hills?

Decks, patios and gazebos have specific rules that override parts of the general accessory framework.

• Attached AND detached decks meet detached-accessory setbacks (§ 138-10.105.B.1). A roof less than 50% open within 10 feet of the principal structure uses principal-building setbacks; an open roof at least 50% open follows deck standards.
• Patios are allowed in side or rear yards with a 5-foot setback from property lines (§ 138-10.105.C).
• Gazebos in RE, R-1 through R-5, RCD, RM-1 and RMH are limited to 180 square feet and one story/16 feet. Their area does NOT count toward the accessory floor-area cap, and they use detached-accessory setbacks (§ 138-10.106).
• The front-yard deck exception allows a deck no wider than the residence and projecting at most 10 feet from its front plane (§ 138-10.102.A.1).

Site-plan exemptions do not remove zoning or building-permit requirements.
