Land Use and Zoning Colorado 4 Minutes Read ยท published March 01, 2026 Flag of Colorado

Westminster, Colorado maintains rules governing historic resources, tree protection, floodplain and wetland areas, and sign regulations that affect homeowners, developers, and businesses. This guide summarizes how those rules are administered, where to find official code language and department contacts, and practical steps to comply, apply for permits, or appeal enforcement actions. Citations link to the city code and department pages so you can review primary sources. For site-specific projects, contact Westminster's planning or public works staff early to confirm applicability and required approvals[1].

Historic Preservation

Westminster's historic preservation program covers designation, review of alterations, and incentives for landmark properties. Local review standards and procedures are set by the city's preservation ordinances and administered by the Planning Division and Historic Landmark Commission. For detailed criteria and application requirements, consult the city preservation page and municipal code[2].

Designated landmarks often require a certificate of appropriateness for exterior changes.

Tree Protection & Landscape Rules

Tree protection and landscape requirements apply to new development, redevelopment, and in some cases to private property when removal affects public trees or protected specimen trees. Standards are found in Westminster's development code and Tree Protection regulations; check the planning division for permits and mitigation requirements[1].

Floodplain & Wetland Regulations

Floodplain development permits, elevation requirements, and wetland mitigation obligations are managed through the City's stormwater and floodplain program and through applicable sections of the municipal code. Projects in mapped floodplains may require engineering studies, floodplain development permits, and coordination with state or federal agencies as directed by city staff[3].

Work in a regulated floodplain typically needs a floodplain development permit before building.

Sign Regulations

Sign rules define types, sizes, locations, and permit requirements for commercial, institutional, and temporary signage. Restrictions vary by zoning district and sign type; the municipal code contains measurement methods and prohibited sign forms. Permit applications and submittal requirements are handled by the Planning Division or Building Permit center depending on sign scope[1].

Penalties & Enforcement

Enforcement is conducted by Westminster's Code Enforcement and Community Development staff, with support from Building and Public Works when related to safety, stormwater, or public infrastructure. Inspection programs and complaint intake are available through official department contact pages. Specific enforcement remedies, fines, and escalation procedures are in the municipal code or enforcement policies; where the cited city pages do not list numeric fines, the text below notes that the amounts are not specified on the cited page.

  • Fine amounts: not specified on the cited page; consult the municipal code for exact monetary penalties[1].
  • Escalation: first, repeat, and continuing offence procedures are governed by code; specific ranges are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, removal or remediation orders, permit revocation, or referral to municipal court are available enforcement tools.
  • Enforcer & complaints: Code Enforcement, Community Development, and Public Works accept complaints and schedule inspections via official contact pages[3].
  • Appeals & review: appeal paths typically include administrative review and municipal court; time limits for appeals are not specified on the cited page.
If you receive a notice, contact the listed city inspector promptly to discuss remedies and next steps.

Applications & Forms

Specific application names and forms (for example, certificates of appropriateness, tree removal permits, floodplain development permits, and sign permit applications) are available from the Planning Division or Building Permit Center. The cited city pages provide links to permit pages or directions to apply; where a specific form number or fee is not published on the cited page, it is noted as not specified on the cited page[2].

Many permit submittals now require digital plan files and a completeness checklist.

How-To

  1. Identify whether your property is in a historic district, floodplain, or subject to tree protections by contacting Planning or reviewing maps.
  2. Gather required documents: site plans, photos, engineering or arborist reports, and proposed sign drawings.
  3. Submit the appropriate permit application to the Planning Division or Building Permit Center and pay any application fees.
  4. Respond to inspection requests, adjust plans per review comments, and obtain final approvals before construction or installation.
  5. If denied, follow the appeals instructions on the decision notice or request an administrative review within the stated time limit.
