Summary
Westminster exempts masonry walls and fences of 4 feet or less, measured from grade on either side, from a building permit under Section 301.2.1 of the Administrative Code. Taller fences and walls fall outside that exemption and need a permit before construction, on top of any height limits the Zoning Code sets for the district.
301.2.1 Building permits. A building permit shall not be required for the following: ... 2. Masonry walls or fences not over 4 feet high from grade on either side. ... Exemption from the permit requirements of this code shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of the technical codes or any other laws or ordinances of the City.

Full Breakdown
2 of the Uniform Administrative Code to list twelve kinds of work a homeowner can build without pulling a building permit. Item 2 on that list is "masonry walls or fences not over 4 feet high from grade on either side," so a wall or fence at or under that height in Westminster does not need a permit application to the Building Official. Cross that 4-foot threshold with a masonry wall or fence, and the exemption no longer applies; the project needs a full permit and plan review before work begins.
030, which caps fences and walls at 6 feet in R1 side and rear yards (8 feet where the property backs a freeway right-of-way), 8 feet in side and rear yards of other zoning districts, and generally 3 feet within a required front setback, with different limits for corner lots and flag lots. The code also warns that being exempt from a permit does not excuse the work from complying with the technical codes or any other city ordinance, so an exempt 4-foot fence still has to meet the zoning height table and materials standards even without a permit application.
Violations & Fines
Building a fence or wall taller than the 4-foot permit-exempt threshold without first obtaining a building permit is unpermitted construction under Section 205.1 of the Administrative Code, charged as an infraction or, at the City or District Attorney's discretion, a misdemeanor. Each day the unpermitted fence stands is a separate violation under Section 205.2, and the Building Official can require it be permitted retroactively or removed.
