Development Plan Impact Alerts for Apartments

2.95

Derivation Chain

Step 1 Open public data for land management

→

Step 2 Lack of awareness of how development around my apartment affects property value

→

Step 3 Integrated monitoring of permits, urban planning, and transportation changes within a radius around the apartment

Problem

Homeowners in their 50s cannot proactively understand the impact of development plans—such as redevelopment, reconstruction, road construction, installation of undesirable facilities, and school relocations—around their apartment on property value and living environment. This information is distributed across local government departments (urban planning, architecture, transportation, environment), and missing the public notice or resident comment submission deadlines means losing the opportunity to assert their interests. This information is also essential for apartment sales and jeonse renewal decisions, but even real estate agents do not systematically monitor it.

Solution

Register your apartment address to automatically collect all urban planning changes, building permits, transportation projects, and environmental impact assessments within a 2km radius, display them on a map, and send immediate alerts when new notices are posted. It briefly analyzes the expected impact of each development plan on 'our apartment' (noise, traffic, view, value) and provides the deadline and method for submitting resident comments.

Target: Ages 45-60, own an apartment, plan to live there for 5+ years, sensitive to real estate value fluctuations.

Revenue Model: Free for one apartment. Premium at 4,900 KRW (approx. $3.70) per month (multi-property monitoring, historical development data, automatic generation of resident comment submission forms, weekly reports).
