Simi Valley Sign Size, Height & Illumination Rules

Land Use and Zoning California 3 Minutes Read · published February 21, 2026 Flag of California

Simi Valley, California regulates signs through its municipal code and Planning Division permits. This guide summarizes how size, height, and illumination are controlled, how to apply for permits, common violations, and enforcement pathways. Exact allowances and limits often depend on zoning district, sign type (wall, freestanding, awning, temporary), and whether illumination or electrical work is required. For precise code text consult the municipal code and contact the Planning Division for pre-application review and permit filing.[1]

How sign rules are organized

Sign regulations in Simi Valley distinguish between permanent and temporary signs, business identification signs, and on-site vs off-site signage. Measurement rules for sign area and maximum height are set by zone and sign type; some zones include additional design standards and setback requirements.

Always check zone-specific rules before designing a sign.

Common size, height, and illumination provisions

Typical topics covered in the code and permit process include:

  • Sign area limits by frontage and zoning.
  • Maximum sign heights for freestanding signs and pylons.

Exact numeric limits (square footage, height in feet, lumen or lighting hours) vary by zoning and are specified in the municipal code and permit handouts; consult the code and Planning Division for the current numeric standards.[1]

Design review and variances

Where a proposed sign does not meet dimensional or illumination standards, applicants may pursue variances or design review as allowed by the zoning ordinance. Minor deviations may be addressed through administrative adjustments where the code authorizes them; major changes typically require a formal variance or conditional use permit and public notice.

Penalties & Enforcement

Enforcement of sign regulations is handled through administrative and code enforcement channels. Common enforcement actions include notices to comply, stop-work orders for unpermitted installations, and abatement. The Planning Division and Code Enforcement coordinate inspections and complaints; electrical violations are enforced through Building & Safety.

  • Fine amounts: not specified on the cited page; see the municipal code and enforcement pages for numeric penalties.[1]
  • Escalation: first, repeat, and continuing offence procedures not specified on the cited page.
  • Non-monetary sanctions: orders to remove or modify signs, stop-work orders, and abatement by the city.
  • Appeals and review: appeal routes and time limits are established in the municipal code or administrative procedures; specific time limits are not specified on the cited page.
  • Enforcers and complaint filing: Planning Division and Code Enforcement handle complaints; contact details on the Planning Department pages.[2]
Unpermitted illuminated signs often trigger both planning and electrical enforcement actions.

Applications & Forms

The primary application is the Sign Permit application available from the Planning Division; fee amounts and submittal checklists are provided on the city permit pages or at the counter. If the sign is illuminated, an electrical or building permit from Building & Safety is typically required as a separate submittal. Specific form names, numbers, and fees are listed on the Planning Division web pages and permit packet materials.[2]

Action steps

  • Confirm zoning and permitted sign types for your site.
  • Prepare scaled drawings showing sign area, height, mounting, and illumination details.
  • Request a pre-application review with Planning to identify variances or design review needs.
  • Submit the Sign Permit and pay applicable fees; obtain Building & Safety permits for electrical work if needed.
  • Schedule inspections and comply with any correction notices to avoid fines or abatement.
Start the permit process before contracting fabrication or installation.
