R-1 — Residential
Ferndale sets no maximum lot coverage in R-1. The code works in the opposite direction. Instead of capping what you build, it sets a floor on what stays green: at least 25 percent of the lot must be green space. On top of that, 50 percent of the front yard and 50 percent of the combined side yards must be landscaped green space. Permeable pavers do not count toward these minimums (Sections 2.06, 2.08).
