Permits, zoning and plan review

Most ADU projects require review for zoning compliance, building permits, plan review, and inspections. Typical checks include allowed use in the zoning district, maximum unit size, parking, setbacks, utility connections, and compliance with the adopted International Residential Code as applied by the City of Amarillo. To begin, submit a building permit application and required plans to the City building services portal or office. City building services - permits[2]

Penalties & Enforcement

The City enforces ADU rules through its code compliance and building inspections functions. Specific monetary fines, escalation, and exact sanction amounts for ADU violations are not consistently published on the primary ordinance pages; where the municipal code or department pages list penalties they are cited below or noted as "not specified on the cited page."

  • Fines: not specified on the cited page; municipal code and building regulations commonly authorize civil penalties and daily fines for continuing violations.
  • Escalation: first offence versus continuing offences are typically handled by progressive notices, civil fines, and potential court referral; exact ranges are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, orders to remove or disable an unlawful ADU, permit revocation, liens, or abatement actions are available under building and code authority.
  • Enforcer & complaints: Building Inspections and Code Compliance enforce construction and use rules; complaints are submitted via the City building services or code compliance contact pages. Contact building services
  • Appeals and review: permit denials and enforcement orders commonly carry appeal routes to the city review board or municipal court; time limits for appeal are not specified on the cited page.
Always preserve documentation of plans, permits, and inspection results when you build or occupy an ADU.

Applications & Forms

The City publishes a standard building permit application and plan submittal checklist on its building services pages; permit fees and required submittals (plans, energy compliance, plumbing/electrical permits) are listed there when available. If a numbered or named ADU-specific form is required, it will be on the City permit forms page; otherwise submit a standard residential building permit with ADU plans.[2]

  • Common forms: Building Permit Application, plan checklist, trade permits (electrical, plumbing, mechanical).
  • Fees: fee schedules are published by the City; if a specific ADU fee line item is not published, fees are calculated per the adopted fee schedule on the building services page.
  • Deadlines: plan review and permit timelines follow the City review process; expedited review availability is not specified on the cited page.

Common violations

  • Occupancy without a permit (unpermitted rental ADU).
  • Constructing beyond allowed size or encroaching on setbacks.
  • Failing required inspections or altering approved plans.
If you receive a notice, respond promptly and request inspection or appeal instructions in writing.
