Summary
In Beaverton's RMB and RMC residential zones, buildings top out at 35 feet, but drop to 25 feet near the front or rear setback line under a 2022 rule.
Buildings in the RMB and RMC districts can be built up to the maximum height in the zone (35 feet), except near the front and/or rear setback. Additional height limitations apply as follows:
A. In the RMB district, the maximum building height at the rear setback line is 25 feet.

From the applicable setback line specified in A. or B., the maximum height rises at a 45-degree angle (a rate of 1 foot vertically for every 1 foot horizontally) toward the center of the lot until it reaches a maximum of 35 feet. See Figure 20.30.10).

Full Breakdown
Beaverton's Development Code caps building height at 35 feet in the RMB and RMC residential zones: its two lowest-density, mixed-housing districts inside city limits, Washington County, Oregon. Near the front and/or rear setback, that cap steps down: 25 feet at the rear setback line in RMB, and 25 feet at both front and rear setback lines in RMC. From that line, allowed height rises at a 45-degree angle toward the lot's center until it reaches the full 35 feet. Townhouses and cottage clusters are exempt from this stepped limit.
Violations & Fines
Design Review under Development Code Chapter 40 checks compliance before permits issue; building over the stepped limit is a code violation subject to city enforcement and permit denial or revision.
