Summary
Lane Code sets no maximum building height in the Rural Residential (RR) zone: LC 16.290(7)(f) reads simply "Height. None." A homeowner on RR-zoned land outside Eugene, Springfield or another city can build as tall as the Oregon Residential Specialty Code and site conditions allow, with no zoning ceiling.
(7) Property Development Standards. All uses or development permitted by LC 16.290(2) through (4) above, except as may be provided therein, shall comply with the following development standards: ... (f) Height. None.
Full Breakdown
LC 16.290 governs the Rural Residential (RR) zone under the Rural Comprehensive Plan, the zone applied to the RR1, RR2, RR5 and RR10 minimum-lot-size designations that cover most unincorporated land outside the coast range's forest and farm zones. Subsection (7), "Property Development Standards," applies to every use or development permitted under LC 16.290(2) through (4), and it sets specific numeric limits for setbacks (20 feet from a state, county or local-access road right-of-way; 10 feet from all other property lines), riparian buffers (50 feet from Class I stream ordinary high water) and signs (200 square feet, no illumination or movement).
Height, by contrast, is addressed and answered in two words: LC 16.290(7)(f) reads "Height. None." There is no local ceiling on how tall a house, barn, shop or accessory building can be in the RR zone. That silence is deliberate: the same subsection regulates setbacks, riparian buffers, signs and parking in detail, so the absence of a height number is not an omission, it is the standard. A structure still has to meet the Oregon Residential Specialty Code's engineering and life-safety requirements, and a lot inside the Commercial Airport Safety or Airport Safety Combining Zones (LC 16.245, LC 16.246) can be capped by those overlay standards even though the base RR zone imposes none.
Building permits for new construction go through Lane County Land Management, and permit review checks the LC 16.290(7) setback, riparian and sign standards even where height is not at issue.
Violations & Fines
Because LC 16.290(7)(f) sets no height limit, there is no height violation to enforce in the RR zone itself. Enforcement instead attaches to the setback, riparian-buffer and sign standards in the same subsection, and to any building-permit or overlay-zone requirement a tall structure must still meet. Lane County pursues those violations under the county's general administrative enforcement chapter, LC 5.025: an Enforcement Officer issues an Order to Comply identifying the violated code sections and a compliance deadline, after which civil penalties accrue at up to $2,000 per violation per day ($2,500 per day in cases involving commercial gain) until the violation is corrected.
