Sign Regulations in Manteca, CA: What Residents Actually Need to Know

If you live in Manteca or are thinking about moving there, sign regulations are one of those things you probably won't think about until they affect you directly. Manteca has 6 specific rules on the books covering different aspects of sign regulations, and some of them might surprise you.

Political Signs

Manteca exempts noncommercial signs, including political signs, from a Sign Permit on private property, capping each at 32 square feet and requiring removal within seven days after the election or event.

Key details: Sign permit: Not required. Size cap: 32 sq ft per sign. Removal deadline: 7 days after election/event. Placement: Private property only. Right-of-way: Signs not allowed there.

A political sign larger than 32 square feet, one left up more than seven days after the election, or one planted in the public right-of-way violates the sign code and can be ordered removed.

Manteca is more permissive than most cities when it comes to political signs. That said, there are still limits.

Garage Sale Signs

Manteca allows up to four garage or yard sale signs, each capped at six square feet, without a Sign Permit, but the signs can't be attached to utility or street sign poles.

Key details: Sign permit: Not required. Max signs: 4 per sale. Max size: 6 sq ft each. Utility/street poles: Signs may not attach. Sale frequency: Separately capped, § 17.84.050.

Posting more than four garage-sale signs, oversized signs, or signs zip-tied to a utility or street sign pole is a sign-code violation Code Enforcement can order removed.

If you are coming from a city with tighter rules, you will find Manteca gives residents more flexibility on garage sale signs.

Window Signs

Manteca exempts permanent window signs from a sign permit, but caps them at four square feet per street frontage and bans illumination, per the zoning code's exempt-signs list.

Key details: Sign permit: Not required if compliant. Size cap: 4 sq ft per frontage. Illumination: Not allowed. Placement: Interior or exterior of window. Over the cap: Requires a Sign Permit.

A window sign over four square feet per frontage, or an illuminated one, loses its permit exemption; operating without the required Sign Permit is a zoning violation Code Enforcement can act on.

Manteca is more permissive than most cities when it comes to window signs. That said, there are still limits.

Digital Billboards

Electronic/digital display signs are allowed in Manteca only as part of an approved Regional Recreation/Hospitality Center project, and only after the City Council grants a Conditional Use Permit on the Planning Commission's recommendation.

Key details: Allowed use: Regional Recreation/Hospitality Center only. Approval: Conditional Use Permit. Decision body: City Council. Off-site ads: need special Council finding. Notice period: 10 days before hearing.

Operating an electronic display sign outside an approved Regional Recreation/Hospitality Center CUP, or running off-site advertising without Council authorization, violates Chapter 17.54 and defaults to an infraction with escalating fines under § 1.16.010.

This is not one of those rules that cities tend to ignore. Manteca actively enforces its digital billboards requirements.

Freeway-Facing Signs

Freeway-oriented freestanding signs in Manteca must be monument-style, well-proportioned, incorporate "Manteca" in the design, and are capped at 500 square feet per face and 75 feet in height within 1,000 feet of a state highway.

Key details: Max area: 500 sq ft per face. Max height: 75 feet. Location limit: within 1,000 ft of state highway. Design requirement: must say "Manteca". Permit: building permit required.

Signs installed without the required building permit, or built to different dimensions or design than approved, are code violations; unless a stricter penalty applies, violations default to an infraction carrying escalating fines up to $500 per repeat offense under § 1.16.010.

Holiday Displays

Manteca's sign code excludes holiday and cultural observance decorations from sign regulation entirely, so long as the display runs no more than 45 calendar days per year and carries no commercial advertising message.

Key details: Max display period: 45 calendar days/year. Measured: Per parcel or use. Commercial advertising: Not allowed. Sign permit needed?: No, within 45 days.

Displays that exceed 45 days per year or add commercial advertising lose the sign-definition exclusion and must obtain standard sign permitting under Title 17; unpermitted signage is enforced under MMC Chapter 1.10 per § 17.14.010.
