Why do you need to look at the 'building deed' when buying a property?

Why do you need to look at the 'building deed' when buying a property? Fatal details that novice buyers are most likely to overlook

Last month, my client Kelvin finally saved enough for a down payment and was ready to buy his first property. When viewing the unit, he was very satisfied with the layout, the view, and the transportation, and the price was also considered reasonable. However, when the law firm reviewed the documents, they discovered that the building's deed stipulated 'no pets allowed' — and Kelvin had a golden retriever that had been with him for many years. In the end, he could only painfully give up this desired unit, wasting the deposit and legal fees.

This real-life case tells us: Buying a property is not just about the unit itself; the building's deed of mutual covenant, this 'invisible contract,' often determines the quality of life after moving in and can even affect the resale value of the property. According to data from the Estate Agents Authority, about 15-20% of sales disputes each year are related to buyers not understanding the terms of the building’s deed of mutual covenant. In today's article, I will use my 15 years of real estate experience to break down the key content of the building’s deed of mutual covenant and teach you how to avoid hidden pitfalls on your property purchasing journey.

What is a Building Deed? Why It Is More Important Than You Think

Legal Status of the Building Deed

The Deed of Mutual Covenant (DMC) is a legally binding document formulated by the developer when the building is completed. It regulates the management structure of the entire building, the rights and responsibilities of owners, and various usage restrictions. Once you sign the sale and purchase agreement, it means you agree to abide by all the terms in the DMC — even if you have never read through its contents.

:::tip Expert Tips The legal effect of a building deed is equivalent to a contract; violating its terms can be pursued by the owners' corporation or management company, and may even face legal action. This is not a 'reference document,' but a 'mandatory set of rules.' :::

Core Areas Covered by the Charter

A complete building deed usually includes the following contents:

  • Property Management Structure: Appointment of the management company, composition of the owners' corporation
  • Rules for Use of Public Facilities: Rights to use and charging standards for clubhouses, swimming pools, and parking lots
  • Unit Usage Restrictions: Whether pets are allowed, whether commercial activities are permitted, restrictions on renovation times
  • Maintenance Responsibilities: Who is responsible for repairing exterior walls, public facilities, windows, etc.
  • Management Fees and Miscellaneous Charges: How they are calculated, when adjustments are made, consequences of arrears
  • Resale Restrictions: Certain estates may restrict owners from reselling within a specified period

:::highlight Key Reminder The contents of the deed of mutual covenant vary greatly across different eras and developers. The deed of mutual covenant for old buildings may only have a few pages, while that of new developments can be hundreds of pages thick, with clauses as complex as those in commercial contracts. :::

Why Do Buyers Easily Overlook the Deed?

According to my many years of observation, more than 70% of first-time homebuyers have never fully read the building's deed of mutual covenant before signing. There are three reasons for this:

  1. Documents are lengthy and difficult: Legal documents often run from dozens to hundreds of pages, filled with professional terminology.
  2. Time pressure: The Hong Kong property market moves quickly, and buyers are often eager to place deposits, leaving little time for careful review.
  3. Over-reliance on agents: There is a misconception that real estate agents will highlight all important matters (in reality, agents may not be familiar with the details of each deed).

But it is precisely this 'settling for' mentality that lays countless hidden dangers for the future.

5 Major 'Landmine Spots' in Building Deeds: Real Case Analysis

Case 1: Pet Clause – Beloved Dog Becomes a 'Violation'

Background: Amy bought a two-bedroom unit in Tseung Kwan O, and only after moving in did she discover that the deed explicitly prohibited keeping any pets. The management office sent multiple warning letters, and eventually, she was forced to give away the cat that had been her companion for many years.

Sample Deed Clauses:

"Owners and residents shall not keep, breed, or allow any animals (including but not limited to cats, dogs, birds, reptiles) to enter or stay in the unit."

:::warning Guide to Avoiding Pitfalls Even if you see your neighbor keeping pets, it doesn't mean you are allowed to keep one. The management office may enforce the rules selectively, or the neighbor may be an 'old deed' owner (having kept pets before moving in, protected by a 'grandfather clause'). Before buying a property, be sure to confirm the pet policy with your lawyer and obtain written confirmation. :::

Insider Tip: Some estate deeds specify that 'small pets (such as dogs weighing no more than 20 pounds) may be approved at the discretion of the management office.' If you need to keep pets, you should prioritize choosing estates with such 'flexible clauses.'

Case 2: Renovation Restrictions — Drilling Walls Not Allowed on Weekends

Background: After buying a unit in a housing estate in Tsuen Wan, Jason plans to renovate it on the weekend. However, the Deed of Mutual Covenant stipulates that "the decoration time is limited to 9 am to 5 pm from Monday to Friday, and any noise works are strictly prohibited on weekends and public holidays". Since Jason had to go to work, he could only pay the decorator an additional "weekday wage", which increased the cost by nearly 30%.

Common Renovation Restriction Clauses:

  • Renovation time restrictions (e.g., no construction after 7 PM)
  • Materials must be transported using designated elevators
  • Renovation deposit must be submitted to the management office (usually $5,000-$20,000)
  • No alterations to exterior walls, windows, or balcony structures

:::tip Experts recommend When buying a property, you should request the 'Renovation Guidelines' from the management office to understand specific restrictions. If you plan a major renovation (such as combining rooms or changing the location of the kitchen or bathroom), you need to further confirm whether the deed allows structural wall modifications. :::

Case 3: Parking Space Usage Rights — Bought a Building but Can't Park

Background: David bought a unit with a parking space in Ma On Shan, but after moving in, he discovered that the deed stated that "the parking space is for private cars only and not for trucks, vans, or modified vehicles." His seven-seater was repeatedly denied entry to the car park by management because it was considered a "van."

Parking Space Related Terms and Pitfalls:

  • The parking space and the unit are sold under "sub-deed" and may not be tied up when resold in the future
  • Some housing estates stipulate that "visitor parking spaces are not allowed overnight"
  • The installation of electric vehicle charging facilities requires approval from the management office (some old buildings do not have relevant terms in the Deed of Mutual Covenant, resulting in the owner not being able to install chargers)

:::success Practical Advice If you need a parking space, you should confirm before signing the contract: (1) whether the parking space is registered under the same deed as the unit; (2) whether the joint deed restricts the type of vehicle; (3) whether an electric vehicle charging facility can be installed. These details directly affect the property's practicality and resale value. :::

Case 4: Clubhouse Facility Usage Fee — 'Free' Clubhouses Actually Charge Fees

Background: Sarah was attracted to the luxury clubhouse of the new development, thinking she could use it for free after moving in. However, the deed specified that "clubhouse facilities require additional fees, $50 per visit for the swimming pool, $300 per month for the gym." She only realized after moving in that the monthly clubhouse fees alone would cost an extra $500-$800.

Hidden Clubhouse Charges:

  • Some facilities require additional fees (such as the billiard room and karaoke room)
  • Management fees do not include clubhouse maintenance fees; in the future, a 'special levy' may be required
  • Certain residential estates require 'non-owner residents (such as tenants) to pay a deposit' to use the clubhouse

:::highlight Expert analysis Developers heavily promote clubhouse facilities when selling properties, but the deed of mutual covenant often transfers the operating costs of the clubhouse to the owners. Before buying a property, one should carefully read the 'Clubhouse Usage Rules' attached to the deed of mutual covenant to understand the actual costs. Some estates' clubhouses operate at a loss for long periods, and ultimately all owners need to 'chip in' to cover the deficit. :::

Case 5: Management Fee Adjustment Mechanism — Can Afford to Buy but Not to Pay

Background: Michael bought a unit with a management fee of "$3 per square foot," which he thought was reasonably acceptable. However, the deed states that "the management company has the right to adjust the management fee annually according to the inflation rate, without needing approval from the owners' meeting." Three years later, the management fee has risen to $4.2 per square foot, an increase of 40%.

Traps in Management Fee Clauses:

  • Some deed of mutual covenant grants the management company the power to "unilaterally adjust management fees"
  • Management fees in certain estates include a "reserve fund," used for future major repairs (such as exterior wall renovations, elevator replacements)
  • Arrears in management fees may incur legal costs and even affect property resale

:::warning Risk Warning Management fees are the "invisible payments" after buying a property, directly affecting your cash flow. When purchasing a property, you should request the past 3-5 years of management fee adjustment records from the management office to assess future trends. In some older buildings, due to high maintenance needs, management fees may rise sharply in a short period. :::

How to Review a Building's Deed? 5 Practical Steps

Step 1: Request a complete copy of the deed from the lawyer

After signing the provisional sale and purchase agreement, your lawyer will request a copy of the building's deed from the seller's lawyer. Do not rely on the 'summary version' provided by the real estate agent, as summaries often omit critical details.

Timeline: Usually receive a copy of the deed within 7-14 days after signing the provisional agreement.

Step 2: Key Review of 8 Major Clauses

Even if the deed is hundreds of pages thick, you should prioritize reviewing the following areas:

  1. Pet Clauses: Whether pets are allowed, any size/breed restrictions
  2. Renovation Restrictions: Time limits, structural modification restrictions, deposit requirements
  3. Parking Space Usage: Whether the parking space is deeded, vehicle type restrictions, installation of charging facilities
  4. Clubhouse Facilities: Usage fees, maintenance responsibilities, tenant usage rights
  5. Management Fee Calculation: Charging standards, adjustment mechanisms, consequences of arrears
  6. Resale Restrictions: Whether there is a "no-sale period", right of first refusal clauses
  7. Maintenance Responsibilities: Who is responsible for the maintenance of windows, exterior walls, and rooftop
  8. Commercial Activity Restrictions: Whether operating an online store, tutoring center, etc., from home is allowed

:::tip Experts recommend If you do not understand legal terms, you can ask the lawyer to provide a 'key summary' and give written confirmation on the areas you are concerned about (such as keeping pets or renovations). The lawyer's fee already includes the service of reviewing the deed, so do not waste this right. :::

Step 3: On-Site Inspection of the Management Office's Implementation Strength

The terms of the deed are one thing, and the enforcement by the management office is another. I suggest you:

  • Visit the management office: Inquire about how common violations (such as pets and renovation complaints) are handled
  • Observe the estate environment: For example, if you see many households keeping pets, it may indicate that the management office enforces rules leniently
  • Review the owners' corporation meeting minutes: Understand whether there have been past disputes arising from deed restrictions

Insider Tip: In some housing estates, the management offices 'ignore the rules,' rendering the deed effectively meaningless. But this is not necessarily a good thing—when you need the management office to enforce rules (such as complaining about a noisy neighbor), they may just as well 'turn a blind eye'.

Step 4: Compare the Deed of Mutual Covenant terms of estates in the same district

The strictness of the deed of mutual covenant varies greatly between different housing estates. If you are hesitating between several estates, you should compare their deed of mutual covenant terms:

| Clause Category | Estate A (More Lenient) | Estate B (Stricter) | |-----------------|-------------------------|-----------------| | Pet Policy | Small dogs and cats allowed | Completely prohibited | | Renovation Hours | Monday to Saturday 9am-6pm | Weekdays only 9am-5pm | | Management Fee Adjustment | Requires owners' meeting approval | Management company can adjust unilaterally | | Clubhouse Charges | Free for owners | Some facilities require additional fees |

:::success Property Investment Strategy If you value flexibility in life (such as having pets or flexible renovation times), you should prioritize residential complexes with more lenient deed restrictions. Although the management of such complexes may be relatively 'loose,' at least you will not be restricted in every aspect. :::

Step 5: Keep written records to avoid future disputes

If a lawyer or management office has made an oral promise regarding the terms of the deed (such as 'small dogs are allowed'), be sure to request a written confirmation from them. Oral promises are difficult to prove legally, and if a dispute arises later, you will be in a disadvantageous position.

Recommended Documents to Keep:

  • Lawyer’s deed review report
  • Written responses from the management office (e.g., approval letters regarding pets or renovations)
  • Minutes of the owners’ corporation meetings (e.g., involving amendments to the deed)

Special Situations: Pitfalls in Deeds of Old Buildings, Village Houses, and Tong Lau

Old Building Deeds: Outdated Clauses, Difficult to Enforce

Old buildings completed in the 1960s-1980s often have very simple deed contents, and sometimes there is no clear management structure. Common problems include:

  • No owners' corporation: Difficult to coordinate maintenance and management matters
  • Unclear maintenance responsibilities: When exterior walls peel or the rooftop leaks, owners shift the responsibility to each other
  • Difficulty in collecting management fees: Some owners default for a long time, leading to building disrepair

:::warning Risk Warning Before buying an old building, you should check the records of the 'Building Repair Orders' (available on the Buildings Department website). If the building has received repair orders multiple times, it indicates poor management and there may be large maintenance costs to pay in the future. :::

Village House Deed: Complex Land Ownership

The concept of a 'Deed of Mutual Covenant' for village houses is different from that of private housing estates, mainly involving land ownership issues:

  • Ding House: Need to confirm whether the seller is an indigenous inhabitant, and whether there are transfer restrictions on the land deed.
  • Ancestral Hall Land: The land is jointly owned by multiple members of the "hall," and resale requires unanimous consent.
  • Illegal Construction Issues: Unauthorized building on village houses is common; before buying, it is necessary to check if there is a "demolition order."

Insider Advice: Before buying a village house, be sure to hire a lawyer familiar with land ownership in the New Territories, and request the seller to provide a 'Boundary Map' and a 'Land Search Record' to ensure clear ownership.

Tong Lau Deed: Almost 'No One in Charge'

Before the war, Tong Lau buildings usually did not have formal deeds, and management was extremely loose:

  • No management company or owners' corporation
  • Public areas (such as stairs and rooftops) are not maintained
  • Neighbor disputes (such as noise and hygiene) are difficult to resolve

:::highlight Investment perspective Although Tong Lau have lower prices, their future maintenance costs are high and reselling is difficult. Unless you plan to hold it long-term and live in it yourself, it is not recommended for first-time homebuyers to choose a Tong Lau. :::

Summary: The Building Deed is your 'Real Estate Handbook'

Buying a property is a major life decision, and the building's deed is like a product's "instruction manual" — it determines the quality of life after moving in, the property's ability to retain value, and the ease of resale in the future. Based on my 15 years of experience in real estate, more than 80% of property purchase disputes stem from buyers not carefully reading the deed before signing the contract.

Review the 5 key points of this article:

  1. The deed of mutual covenant (DMC) of a building is legally binding, and violations of its terms can result in liability.
  2. Pets, renovations, parking spaces, clubhouse, and management fees are the most common "minefields."
  3. Reviewing the DMC requires time and professional knowledge, so do not rely too heavily on real estate agents.
  4. Inspect the management office in person to assess enforcement, and understand the actual implementation of the DMC.
  5. Keep written records to avoid disputes where "things said are considered not said" in the future.

Buying a property is not just about being able to 'afford it'; it also needs to be 'comfortable to live in' and 'easy to sell.' Taking the time to understand the building's deed of mutual covenant is like buying an extra insurance for your home ownership journey. Remember: The devil is in the details, and the deed holds hidden secrets.
