**建築図面なし、建築確認なし、旧耐震建築物

実は、新築や改築が完了した後に完了検査を受け、「検査済証」が交付された建物の数は、竣工が古くなるほど少なくなる。国土交通省がまとめたデータによると、1998年度時点の完了検査率（検査済証交付件数／建築確認件数）は38％だが、以前は15％程度だったといわれている。

国や地方自治体は、この完了検査と1999年から導入された中間検査を組み合わせて検査率を高める3カ年計画（2002〜2004年）を実施し、建築違反の取り締まりを強化している。さらに国土交通省は2003年、完了検査に基づく検査済証のない建物への住宅ローン融資を自粛するよう金融機関に要請した。

昔に比べれば完了検査の実施率は格段に上がっているが、2012年度時点では、特定行政庁（建築主事）による検査が85％、指定確認検査機関による検査が91％となっている。法令遵守が強く求められる現代においても、約1割の建築物が完了検査を受けていないという事実は、既存建築物ストックの有効活用に根深い問題を投げかけている。

**No building drawings, No building permit., old earthquake-resistant building**

In fact, the number of buildings that have undergone completion inspections after new construction or renovations has been completed and have been issued with an "inspection certificate" is lower the older the construction is completed. According to data compiled by the Ministry of Land, Infrastructure, Transport and Tourism, the rate of completed inspections (number of inspection certificates issued/number of building permits) as of fiscal 1998 was 38%, but it is said to have been around 15% in the past.

The national and local governments have stepped up their crackdown on building violations by implementing a three-year plan (2002-2004) to increase the inspection rate by combining these completion inspections with interim inspections, which were introduced in 1999. Furthermore, in 2003, the Ministry of Land, Infrastructure, Transport and Tourism requested financial institutions to refrain from financing mortgages for buildings that do not have a certificate of inspection based on completion inspections.

Although the percentage of completed inspections is much higher than in the past, as of FY2012, 85% of inspections were conducted by specified administrative agencies (building inspectors) and 91% were conducted by designated inspection agencies. Even in this day and age where there is a strong demand for legal compliance, the fact that approximately 10% of buildings have not been inspected for completion poses a deep-rooted problem for the effective use of existing building stock.

We will introduce an example of using an old building that does not have a building permit.
