Sign Regulations in Moorpark, CA

If you live in Moorpark or are thinking about moving there, sign regulations are one of those things you probably won't think about until they affect you directly. Moorpark has 5 specific rules on the books covering different aspects of sign regulations, and some of them might surprise you.

Garage Sale Signs

Moorpark caps garage-sale signage at six off-site directional signs, sized no larger than two feet by two feet, and requires written property-owner permission before posting any.

Key details: Sign limit: 6 off-site directional signs max. Size limit: 2 feet by 2 feet. Property permission: Written owner consent required. Removal: Taken down each day after sale. Placement ban: No utility poles or right-of-way.

Signs left up after sale hours, oversized signs, signs on utility poles or in the right-of-way, or signs posted without the property owner's written consent violate the code.

Window Signs

In Moorpark shopping centers, permanent window signs are capped at 25% of window area, and temporary window signs top out at 50% for up to 15 days per event.

Key details: Permanent window signs: Max 25% of window area. Temporary window signs: Max 50% of window, 15 days. Frequency limit: 4 events/year, 30 days apart. Permit: No sign permit required.

Exceeding the 25%/50% window coverage caps or running temporary signs past the 15-day/four-times-a-year limit makes the sign illegal, subject to removal or citation under Chapter 1.10's misdemeanor/infraction penalties.

Holiday Displays

Temporary holiday signs and displays on commercial or industrial buildings in Moorpark fall outside the sign code's definition of "sign," so no permit or area cap applies to them.

Key details: Definition section: Sec. 17.40.020, "Holiday sign or display". Exemption: Excluded from "sign" definition. Where exempt: Commercial and industrial buildings. Permit required: None for exempt displays.

Because qualifying holiday signs are excluded from the sign definition, there is no permit fine; unsafe or abandoned displays can still be cited as illegal signs under the chapter's general enforcement provisions.

Moorpark is more permissive than most cities when it comes to holiday displays. That said, there are still limits.

Digital Billboards

Moorpark bans off-site advertising signs and flashing signs outright, a combination that blocks digital billboards and electronic message displays with moving, blinking or color-changing images. Moorpark Municipal Code Section 17.40.130 lists both as prohibited signs citywide, with electronic copy allowed only on an on-site marquee sign that does not flash or change color.

Key details: Off-site signs (billboards): banned citywide, § 17.40.130(H). Flashing/digital displays: banned, § 17.40.130(E). Electronic copy allowed only: on on-site marquee signs, no flashing. Violation classification: misdemeanor/infraction, daily separate offense. Enforcing agency: Director of Community Development.

Violating Section 17.40.130 is a misdemeanor or infraction under Section 17.56.030(A), enforced by the director of community development, who holds Penal Code Section 836.5 arrest authority for violations committed in the officer's presence under Section 17.56.040. Each day a prohibited sign remains erected is a separate offense, and Section 17.56.030(B) additionally deems an illegal sign a public nuisance subject to summary abatement, with a new nuisance arising every day the condition continues. Sign-removal orders can be appealed to the planning commission and then the city council under Section 17.40.170.

This is one of the stricter rules in Moorpark's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Political Signs

Moorpark regulates political and campaign signs under MMC Chapter 17.40 (Sign Regulations). Size and location restrictions vary by zoning district. Political signs are protected speech under the First Amendment. The city provides campaign sign information on its website with specific guidelines for placement and removal.

Key details: Code Section: MMC Chapter 17.40. Permit Required: No, for temporary political signs. Public ROW: Signs prohibited. Removal of Others' Signs: Misdemeanor (EC §18310). Post-Election: Must remove within deadline.

Signs placed in the public right-of-way or on public property may be removed by the city. Signs exceeding size limits are subject to enforcement. Failure to remove signs after the post-election deadline may result in citation. Contact Code Compliance at (805) 517-6232 for sign regulation questions.
