HOA Architectural Review Workflow: n8n + AI to Google Sheets

Turn HOA architectural requests into a tracked, board-ready workflow—automatically

This HOA Architectural Review Workflow uses n8n + AI to capture each homeowner change request, generate an ARC ID with a 30-day review deadline, summarize and flag it with gpt-6-luna, and log everything in Google Sheets—while keeping both the owner and the board updated by email until a decision is made.

What this workflow does

• Collect submissions through an n8n Form for architectural change requests from homeowners.
• Normalize and track each request: required fields are validated, a unique ARC ID is generated, and the request is timestamped with a 30-day review deadline.
• Handle missing information: if required fields are missing, the workflow appends an error row to a Google Sheets “Errors” tab and emails the board via Gmail.
• AI advisory + owner acknowledgment: for valid requests, it sends details to gpt-6-luna to produce advisory flags, a short board summary, and an acknowledgment note to the owner.
• Log and notify: the workflow appends the full request (including AI output) to the Google Sheets “ARC Requests” tab, emails the owner with the deadline, and emails the board a new-request notification.
• Board decisions: accepts board decisions via a POST webhook, updates the matching Google Sheets row, and continues keeping stakeholders informed.

Use cases

• Prevent HOA architectural requests from “disappearing” into an inbox by creating an auditable ARC pipeline.
• Enable the board to quickly review requests with AI-generated flags and summaries.
• Automatically track deadlines and ensure homeowners receive timely acknowledgments and updates.
