Full Breakdown
Dublin Municipal Code Sec. A requires a permit from the Building Official before any person installs, erects, constructs, enlarges, adds to, alters, repairs, moves, removes, demolishes, converts, occupies, equips, or improves a building, structure, or facility, or any electrical, plumbing, or mechanical installation, except as provided in Sec. 310. A separate permit is required for each building or structure, though the permit can include accessories such as fences, retaining walls, exterior lighting, and sprinkler systems if shown on the approved plans (Sec. B). Private water supply and sewage disposal systems need a separate approval from the Health Officer, and Zone 7 Water Agency approvals must be secured first where they apply (Sec. C). Sec. 24 always needs a permit regardless of the exemption list.
Violations & Fines
Building, erecting, or altering a structure without a required permit, or violating a Building Official directive or the approved construction documents, is prosecuted under Sec. 1.04.030 as a misdemeanor, punishable by up to six months in county jail and a $1,000 fine, or as an infraction at the enforcement officer's discretion under Government Code Sec. 36900. The Building Official may also issue a stop work order under Sec. 7.28.180, halting all cited work immediately until the violation is corrected and resumption is authorized.
