Full Breakdown

2750 of the Eugene Code sets maximum building height by residential zone: 30 feet for a main building in R-1, 35 feet in R-2, 50 feet in R-3, and 120 feet in R-4. Accessory buildings are capped lower: 25 feet in R-2 and 30 feet in R-3 and R-4. 2751(3)(a) adds a step-down rule: in the R-3 and R-4 zones, any portion of a building within 50 feet of an abutting R-1 boundary, or directly across an alley from R-1 land, is limited to 30 feet regardless of the zone's normal maximum.

2751(3)(b)-(c)). 2751(3)(d), though that bonus does not apply in R-1 to accessory dwellings, accessory buildings, or development on alley access lots. 5550(6)(a)3. 6720. The section is current through Ordinance No. 20716, effective January 2, 2025.

Violations & Fines

A building that exceeds its zone's height maximum is an unlawful structure and public nuisance under EC 9.0210, abatable under EC Chapter 6. The city manager may issue a stop work order under EC 9.0230 as soon as work is found to be out of compliance with Chapter 9, and continuing work after the order is independent grounds for additional penalties. EC 9.0270 authorizes an administrative civil penalty under EC Chapter 2, capped at $2,000 per day per EC 2.018(5), with at least five calendar days to correct the violation before a penalty issues unless it poses an immediate threat to health or safety. Penalty notices may be appealed to a hearings officer under EC 2.021, and an unpaid, final penalty becomes a lien against the property.

Frequently Asked Questions

How tall can a house be built in Eugene?
It depends on the zone: 30 feet in R-1, 35 feet in R-2, 50 feet in R-3, and 120 feet in R-4, per Table 9.2750. A 7-foot bonus is added in any zone for roof slopes of 6:12 or steeper, except for R-1 accessory dwellings, accessory buildings and alley access lot development.
Can an R-3 or R-4 building near my R-1 house be built to the full zone height?
No. EC 9.2751(3)(a) limits any portion of an R-3 or R-4 building within 50 feet of an abutting R-1 boundary, or directly across an alley from R-1 land, to 30 feet, regardless of the zone's normal maximum height.
What is the height limit for accessory buildings in Eugene?
Accessory buildings are capped at 25 feet in R-2 and 30 feet in R-3 and R-4 under Table 9.2750; R-1 accessory building height is addressed separately under EC 9.2751(16) and does not receive the steep-roof height bonus.
What happens if a structure is built taller than the code allows?
The city can issue a stop work order under EC 9.0230 and treat the oversized structure as a public nuisance under EC 9.0210. An administrative civil penalty of up to $2,000 per day may follow under EC 9.0270 and EC 2.018 if the violation is not corrected after notice.
