Corvallis, OR Building Setbacks & Zoning: Structure Height Limits (2026)

LDC § 3.1.50, Table 3.1-3 sets the RS-6 Zone's Maximum Structure Height at 30 feet, and that limit cannot exceed any solar envelope already approved for a neighboring property under LDC Chapter 2.18 - Solar Access Permits or Chapter 4.6 - Solar Access, meaning a homeowner's roofline can be constrained below 30 feet if a neighbor holds a recorded Type 2 Solar Access Permit. The Code carves out three exceptions to the 30-foot base height. Architectural projections attached to the structure that are not used for human occupancy, such as chimneys, spires, domes, elevator shaft housings, and towers, can rise to 40 feet.

Cottage Cluster development is instead governed by the separate height provisions of LDC § 4.10.55, reflecting that cluster housing follows its own development standard rather than the standard single-family limit. Flagpoles are governed by the height provisions of LDC § 4.7.70.b, the Sign Code's flagpole standard, rather than the RS-6 table at all. Beyond the RS-6 table itself, LDC § 4.9.50.01 provides general exceptions to building heights and projections that can apply across zones, and a project seeking to exceed the 30-foot base height without qualifying for a listed exception must instead pursue a Development Standards Adjustment under LDC Chapter 2.12.

Owners planning a two-story addition or a tall roof pitch should confirm both the 30-foot base limit and any solar-envelope restriction recorded against the property with the Community Development Department before submitting building plans.
