Summary
Most San Ramon fences need no permit at all, but Municipal Code Section D3-4 requires a Building Permit for any fence or wall inside a mapped flood hazard area, and a Minor Exception or Variance before a fence or wall can rise above the height limits set in Table 3-1 or Table 3-2.
A. Applicability. The requirements of this Section apply to all fences and walls unless otherwise stated. 1. Fences or wall in flood hazard area. A fence or wall in an area subject to flooding identified on a Federal Flood Insurance Rate Map (FIRM) on file in the Engineering Services, Public Works Department shall require a Building Permit. ... 2. Increased fence or wall height - Permit required. The maximum fence or wall height allowed by Table 3-1 or Table 3-2 may be increased with Minor Exception or Variance approval, subject to the required findings in D6-24 (Minor Exceptions) or D6-29 (Variances) and the following requirements. ... Note: Fence height - No permit required. The Zoning Administrator may allow the height of a fence along a side or rear property line and/or within a side or rear setback to be a maximum of seven feet without a Minor Use Permit if the top one foot is constructed of open lattice subject to the approval of the Zoning Administrator; provided that the fence complies with all other applicable requirements of this Section, including the fence material limitations in Subsection E.
Full Breakdown
Section D3-4 applies to every fence and wall in the City except those required by a state or federal agency or by the City for public safety (Section D3-4.A.2). Inside a Federal Flood Insurance Rate Map (FIRM) area on file with Engineering Services in the Public Works Department, any fence or wall first requires a Building Permit (Section D3-4.A.1). Outside a flood zone, a compliant fence built to the Table 3-1 residential or Table 3-2 non-residential height limits needs no permit at all; the Zoning Administrator may even approve a side or rear fence up to seven feet with a top foot of open lattice without a Minor Use Permit, provided the lattice is at least 50 percent air-penetrable (Section D3-4.B.1, Note).
Anyone who wants a fence or wall taller than the table limits must instead obtain Minor Exception or Variance approval, showing compliance with the traffic safety visibility requirements of Section D3-6.F and accepting any conditions the Zoning Administrator sets for aesthetics (Section D3-4.B.2). A property owner may also add an architectural feature up to two feet above a six-foot fence, projecting no more than 18 inches from the posts and not crossing the property line, without a separate permit (Section D3-4.B.3).
Violations & Fines
Building or raising a fence in a flood hazard area, or above the Table 3-1/3-2 limits, without the required Building Permit or Minor Exception/Variance is treated as unpermitted construction, an infraction under the City's general penalty section, Section A1-32, fined up to $100 for a first offense, $200 for a second, and $550 for each additional violation within a year; the fence remains a continuing daily violation under Section A1-33 until it is permitted or removed.
