[Red line for protecting rights when buying a house] Is it reasonable for the builder to only keep 50,000 yuan for the house payment? Legal terms and preliminary re-inspection negotiations on the "5% retention deposit" of the Ministry of Interior's standardized contract

Strong threats from builders: house payments are being maliciously reduced

In the greater Taipei area, purchasing pre-sale houses is an important financial decision for many young families and investors. However, when the house is finally built and ready for inspection and handover, many homeowners often face strong pressure from the builder or sales agent: "The only missing decoration is a few uneven paint. If you don't sign and hand over the house quickly, you won't be able to get the keys, and it will affect the funding period of the housing loan." What's more, many builders privately modify the "handover deposit (handover payment)" in the pre-sale contract to a fixed amount of "50,000 yuan" or "100,000 yuan." This leads to the fact that when the homeowner discovers major defects (such as hollow floor tiles and leaking balconies) during the initial inspection, he does not have enough financial leverage to control the builder. The builder therefore adopts a "put off and perfunctory" attitude towards the repair work, leaving the buyer in a passive abyss of pain. In fact, Taiwanese law has very clear and mandatory red lines regarding the retention money for pre-sale houses that must not be violated.

The red line of the finalized contract of the Ministry of the Interior: a legal guarantee of 5% of the total price of the house

According to Article 19 of the "Items that should be recorded and not recorded in the standardized contract for pre-sale housing sales" promulgated by the Ministry of the Interior of the Republic of China, it is clearly stipulated: The buyer must only pay the final payment after the builder has completely repaired all the deficiencies in the house inspection report and passed the re-inspection by both parties.
Legal fact check:
1. Many builders secretly record in the contract that "both parties agree to pay 50,000 yuan/100,000 yuan for the house." According to Article 17 of Taiwan's Consumer Protection Act, if a stereotyped contract clause violates the "matters to be recorded" announced by the Ministry of the Interior, the illegal clauseis illegal, and the builder shall be subject to a deadline for improvement and penalties by the competent authority. Invalid terms will automatically return to the legal standard of "5% of the total price". For example, for a pre-sale house in Shuangbei with a total price of NT$ 20 million, the legal deposit for handing over the house is as high as NT$ 1 million. This huge sum of money is the only bargaining chip to force the builder's engineering team to make serious repairs.
2. The builder shall not refuse the buyer to enter the room for inspection on the grounds of "failure to complete the house handover procedures", nor shall the builder maliciously withhold the keys and threaten the buyer to sign an "unconditional handover declaration" when the buyer has cooperated in the transfer of property rights.

Compliance negotiation and appeal process for initial inspection and re-inspection

When the home inspection finds deficiencies, the buyer should follow the following regulatory negotiation process to protect his property:
Step 1: Compile the formal "deficiency list": Entrust a professional home inspection company to issue a deficiency report in duplicate. After the on-site representatives of both parties (supervision representatives and sales representatives) sign and confirm, the report will be officially sent to the builder, requiring it to make improvements within the time limit for defect warranty liability in the Civil Code.
Step 2: Specify the re-inspection time in the contract: Both parties agreed to conduct the re-inspection within 14 to 30 days. Before the defects are completely repaired, the buyer has the right to refuse to sign the "House Delivery Consent", and the lending bank is not allowed to directly transfer 5% of the housing payment to the builder's account without obtaining the buyer's written funding consent.
Step 3: Complain to the Consumer Protection Officer:If the builder has a bad attitude and refuses to amend the illegal clauses in the contract, the buyer can directly file an online complaint through the Consumer Protection Council website of the Executive Yuan of the Republic of China (Consumer Protection Council). The Land Bureau and the Consumer Protection Officer will directly intervene in the mediation and impose a deadline on the builder to make improvements. Failure to do so will result in a fine of NT$ 30,000 to NT$ 300,000.

Basic Budget for Complaints and Litigation Agency for Missing House Inspection in Shuangbei

If you have a falling out with the builder and face mediation and legal proceedings, the relevant rights protection budget is approximately as follows:
* Completely free. This is the fastest and cheapest mediation channel.
* Each letter costs approximately NT$ 6,000 to NT$ 12,000. A certified letter formally records the legal date of the notice and claim of defect.
* The first-instance lawyer fees for civil litigation in the Greater Taipei area are about NT$ 80,000 to NT$ 150,000. Usually, if you win the case, you can request damages and interest from the builder.

Commercial acquisitions and businessmen’s long-term asset thinking: Legal bargaining chips are the financial line of defense for controlling project CapEx and maintaining IRR

For commercial businessmen who specialize in acquiring, renovating, and pre-sales projects in Shuangbei Hunting Land, or investing in large-scale apartment properties, When businessmen conduct large-scale property transactions, the 5% clause in the contract is the only protection against the failure of the builder, unfinished construction, or serious construction defects. If a businessman gives up the 5% lien in advance because he is eager to get the house quickly, once a water pipe bursts and a large area of ​​water leaks from the exterior wall is discovered after the house is handed over, the cost of subsequent repairs by self-employed workers will directly increase the initial CapEx, causing the IRR to plummet. Merchants should adhere to the compliant initial and re-inspection standards and keep the 5% balance in their accounts until all water, electricity and fire protection projects pass safely. This strict awareness of legal risk control is a professional survival rule for high-end real estate businessmen to ensure that asset safety and business investment profits are not compromised in high-financial leverage operations.

The latest standards for catching leaks and regulatory responsibilities in Shuangbei collective housing (2025-2026 practice)

According to Article 10 of the "Apartment Building Management Regulations" of the Ministry of the Interior and the trend of civil water leakage judgments in Shuangbei District Court in recent years, most water leakage disputes in old collective housing focus on the identification and definition of "exclusive parts" and "common parts". The roof platform and the public pipes are jointly owned by all separate owners, and the repair costs should be shared by public funds or all residents in proportion to their shares according to law; if the water supply and drainage pipes inside the floor slabs on the upper and lower floors are damaged, the pipes will be borne exclusively by the users or shared by the upper and lower floors.

At the engineering and technical level, modern professional leak detection has fully introduced non-destructive scientific testing, including "FLIR high-resolution infrared thermal imaging camera" (locating temperature difference leakage paths), "high frequency moisture meter" (measuring the moisture content of deep structures) and "pipeline air pressure and water pressure pressure test" (determining whether hot and cold water pipes are leaking). During construction, do not directly apply elastic cement or oil-based paint on the wet cement layer to seal it. Otherwise, the thermal expansion of internal water vapor will quickly cause the coating to blister and peel off, resulting in more serious powdery wall cancer. The standard construction method must first completely eliminate the water source, wait until the moisture content of the cement structure drops below 8%, and then apply the negative pressure resistant silicic acid permeability crystallized waterproof layer.

Recommendations on independent certificate storage and compensation process for water leakage repair

1. Take photos and videos as evidence immediately: Use rulers to record the leakage range, frequency of water discharge, direction of water mark diffusion, and keep time stamps.
2. Written notification and coordination survey: Officially notify the neighbors through the management committee or a certified letter, and agree on a professional third-party leak detection and appraisal unit recognized by both parties to conduct an on-site survey.
3. The contract states the warranty terms: When signing the contract for the project, be sure to clearly specify the waterproofing warranty period (usually 1 year for partial repairs, and 2 to 5 years for the whole room or roof re-construction), and specify the water test acceptance criteria (such as a 48-hour water storage test in the bathroom shower area) to protect your own asset rights.
