Step 3 Missing repair claim deadlines and paying hundreds to thousands out of pocket

Problem

Apartment residents in their 50s discover post-move-in defects (leaks, cracks, condensation, etc.) but the free repair claim deadlines vary by category—interior finishing 2 years, waterproofing 5 years, structural 10 years, etc. Most residents don't know or forget these deadlines, ending up paying out of pocket for repairs that could have been claimed for free. The average defect repair cost per household is estimated at $1,500–$3,750 (200–500만원).

Solution

Users enter their apartment move-in date and complex name on the web, and the system auto-calculates claim deadlines by defect category, displayed as a visual timeline. Alerts are sent 3 months before each deadline. Also provides photo documentation guides by defect type, defect repair claim form templates, and relevant case law summaries. The core value is creating urgency around 'miss it and you pay out of pocket' with concrete action guides.

Target: Ages 45–60, apartment residents 1–9 years post-move-in, have experienced defects but don't know how to file claims
Revenue Model: Basic timeline and alerts free; defect inspection specialist referral commission; defect repair claim auto-fill $3.70 (4,900원)
Ecosystem Role: Regulation
MVP Estimate: 2_weeks
