Definition of dilapidated buildings: What kind of buildings can be called "dilapidated"?
Dangerous old age is based onOrdinance on Accelerated Redevelopment of Dangerous and Old Urban Buildings"Regulations on Dangerous and Old Buildings", Article 3 of which stipulates that dangerous and old buildings are mainly divided into two types: dangerous buildings and old buildings.
⠀⠀⠀⠀
1. Dangerous Buildings
This refers to buildings whose structures or equipment have safety concerns and have been notified by the building authority in accordance with the Building Act to repair, reinforce or demolish them within a specified period of time. Such buildings usually pose a direct threat to residential safety due to factors such as "structural damage", "unstable foundations" or "aging building materials". The building authority will conduct a professional assessment and confirm that the building does indeed pose a safety risk before issuing relevant notifications.
⠀⠀⠀⠀
2. Old Buildings
Old buildings refer to buildings that are more than 30 years old.Structural safety performance assessmentThose whose results do not reach the lowest level; or those whose houses are more than 30 years old, whose earthquake resistance does not meet certain standards, and whose improvements are ineffective or have no lifting equipment installed. This definition covers most of the old residential buildings in Taipei City and provides a legal basis for the reconstruction of these buildings.

Taipei City Elderly Care Query
Taipei City currently does not have a "Dangerous and Old Buildings Query System", but the Taipei City Government has established a completeUrban Renewal Analysis and Query System, and through a variety of inquiry channels, homeowners can easily confirm whether their buildings meet the conditions for urban renewal and reconstruction.
⠀⠀⠀⠀
In addition to online inquiries, the public can also obtain assistance through telephone consultation or counter services. The Taipei City Construction Management Office has a dedicated hotline where professionals provide consulting services to answer the public's various questions about the reconstruction of dilapidated old buildings.

Taipei City's Dangerous and Old Building Reward
⠀⠀⠀⠀
Taipei City's redevelopment of dilapidated and old buildings is not only a key government policy but also a crucial way to improve living quality and enhance urban safety. The Taipei City's volume incentive for dilapidated and old buildings is a key incentive for promoting the redevelopment of old buildings. By increasing building volume, it improves the economic benefits of redevelopment. Below, we also share two other incentives besides the volume incentive!
⠀⠀⠀⠀
Rewards for Dangerous and Old Buildings: 1. Volume Rewards
- The maximum is 1.3 times the base volume (legal volume) or 1.15 times the original volume of the building.
- If the site area is less than 200 square meters (about 60.5 pings) and the age of the adjacent buildings is less than 30 years, a volume bonus of 2% will also be given.
- Dangerous and old buildings: 6% ~ 10%
- Original volume is greater than reference volume: 10%
- Smart Building: 2% ~ 10%
- Setback Building: 8% ~ 10%
- Building seismic design: 2% ~ 10%
- Accessible environment: 3% ~ 5%
- Assist in obtaining development facilities: 5%
- Green Building Level: 2% ~ 10%
- Based on the above dangerous and old volume rewards, the total upper limit is 30% volume rewards.
⠀⠀⠀⠀
Rewards for Dangerous and Old Buildings II. Tax Rewards
- Land tax is exempted during the reconstruction period. However, if the reconstruction is not completed within the construction period and the fault is attributable to the land owner, land tax shall be levied in accordance with the law.
- After reconstruction, land tax and property tax will be halved for two years.
- If the legal owner of a building prior to reconstruction is a natural person and the owner of the reconstructed building has not transferred the property within the two-year period of the half-price property tax reduction as described in the preceding paragraph, the half-price property tax reduction period may be extended until the owner loses ownership, but this limit is ten years.
⠀⠀⠀⠀
Rewards for Dangerous and Old Buildings III. Cost Subsidy
⠀⠀⠀⠀
| Subsidy Projects | Subsidy amount (NTD) |
| Preliminary assessment of earthquake resistance | For buildings with a total floor area of less than 3,000 m², the fee is NT$12,000 per building. For buildings with a total floor area of 3,000 m² or more, 15,000 yuan per building Assessment agency review fee: 1,000 yuan per building |
| Detailed assessment of earthquake resistance | Not more than 30% of the assessed cost or $400,000 per building. |
| Review agency review fees | If the preliminary assessment result does not reach the minimum level, and the applicant submits the certification document of approval by the review agency, NT$6,000 per building A detailed assessment of earthquake resistance shall be conducted at a cost of 15% per building, but shall not exceed 200,000 yuan. |
| Reconstruction Plan | A subsidy of NT$55,000 per case |
⠀⠀⠀⠀
- The maximum value of the initial earthquake resistance assessment is 15,000, and the maximum value of the detailed assessment is 400,000.
- The reconstruction project provides a subsidy of 55,000.
⠀⠀⠀⠀
Taipei City Volume Bonus Calculator
according to"Measures for awarding construction volume of dangerous and old urban buildings"Organize it into the following table:
⠀⠀⠀⠀
base volume
Land area * statutory plot ratio; assuming a plot of land has an area of 800 square meters and the land use zoning is Taipei City Residential District II (the plot ratio is usually 200%).
⠀⠀⠀⠀
👉 Then:
Base volume = 800 × 200% = 1,600 square meters
⠀⠀⠀⠀
Original building volume
"Original building volume" refers to the actual floor area of buildings that were legally constructed before the implementation of volume control, deduced based on current regulations.
When many old houses were built, the government did not have such strict restrictions on the floor area ratio, so the actual floor area built often exceeds the current statutory floor area ratio.
As long as these types of buildings are approved by the competent authorities and confirmed to be not being used illegally, they can apply for additional urban renewal or dilapidated building volume incentives during future reconstruction, ensuring that the new building volume will not be reduced compared to the original, and may even have the opportunity to be slightly larger. This system is mainly designed to prevent homeowners from "building smaller and smaller" during reconstruction due to changes in regulations, and further encourage the renovation of old communities to improve safety and quality of life.
