Solar permitting in Allen, TX

1. #1

   Project Permit Transmittal Letter

   Contractor cover letter that introduces the submittal package to the plan reviewer. Editable before sending.

   NEC Warning Labels

   NEC-mandated placards (rapid shutdown, PV disconnect, dual power source, etc.) sized for label printing. Requires DC voltage/current values from your design.

   Allen note: Allen enforces NEC 690.12 rapid shutdown strictly — labels must be installed at the PV system disconnect AND the service equipment. Verify placement against the AHJ's photo checklist before final inspection.

   Portal Submission Cheat Sheet

   One-page reference with values to paste into Allen's permit portal. Print or keep on a second monitor while submitting.

   Allen note: Not a substitute for submission — installer still types values into the portal manually. TexPTO does not automate portal submissions.

   HOA Approval Request Letter (draft)

   AI-drafted letter to the homeowner's HOA requesting approval for the solar installation. Review, edit, and sign before sending.

   Allen note: Most Allen subdivisions (Starcreek, Twin Creeks, Watters Creek, etc.) require written HOA approval before the city will issue a permit. Check the specific subdivision's ACC process.

    Short AI-drafted blurb sized to paste into the AHJ portal's Description of Work field (typically 150-250 words).

• Missing required safety placard content
• Incomplete roof/array layout fire-access dimensions
• Missing Rapid Shutdown placard (NEC 690.12)
• VLLD distance exceeded (>10 ft Oncor limit)
