Buying a new condominium is one of the biggest decisions you will make. The excitement builds from the moment you sign the Option to Purchase. But for many buyers, the most confusing part comes later. It is the moment the developer says the project is ready for a Temporary Occupation Permit, or TOP. If you are an owner at The Hill at One North, understanding this process helps you plan your move, your finances, and your renovation schedule with confidence.

What Is a Temporary Occupation Permit and Why Does It Matter

A Temporary Occupation Permit is the official green light from the Building and Construction Authority (BCA). It confirms that the building is safe for people to occupy. Without TOP, no one can legally live in the unit. For buyers at The Hill at One North, receiving TOP means you can finally take possession of your home.

The developer applies for TOP after all major construction work is done. This includes structural completion, M&E (mechanical and electrical) installation, and the finishing of common areas. BCA officers then inspect the development to ensure it meets safety and building code standards. Once approved, the developer can hand over the keys.

The Typical Timeline for TOP at The Hill at One North

Every project has its own schedule, but a general timeline helps you set expectations. Here is how the months usually break down.

• Structural completion (3 to 4 months before TOP): The building frame is finished. Roofing, external walls, and windows are in place.
• Internal fitting and M&E works (2 to 3 months before TOP): Plumbing, wiring, air conditioning, and fire safety systems are installed. Unit interiors receive their final finishes.
• Pre-TOP inspection (4 to 8 weeks before TOP): The developer invites you to view your unit. This is your chance to spot any visible defects.
• BCA inspection and approval (2 to 4 weeks before TOP): BCA officers conduct their checks. They may require minor rectifications before issuing the permit.
• TOP granted (target date): The developer receives the permit. You are notified and invited to schedule your defect walkthrough and key collection.

This timeline can shift due to weather, supply chain issues, or contractor availability. Your developer should provide regular updates. If you are planning your move, it is wise to build in a buffer of one to two months after the expected TOP date.

Step 1: The Pre-Top Inspection

Before BCA gets involved, the developer will arrange a pre-TOP inspection for buyers. This is not the same as the defect walkthrough that happens after TOP. It is an early look at your unit while construction is still finishing up.

What should you do during this visit?

• Bring a checklist. Note down any cracks, uneven surfaces, or misaligned doors.
• Check the windows and sliding doors for smooth operation.
• Look at the plumbing. Turn on taps and flush toilets if possible.
• Inspect the electrical points. Make sure switches and sockets are properly installed.
• Take photos of everything. They will help you remember issues later.

This is also a good time to measure your rooms. You can start planning your furniture layout and renovation works. Just remember that minor adjustments may still happen before the final handover.

Step 2: The BCA Inspection and Approval

The developer submits the application for TOP once the building is substantially complete. BCA officers then conduct a thorough inspection. They check for compliance with the Building Control Act, fire safety regulations, and accessibility requirements.

Common areas such as corridors, lift lobbies, and the swimming pool are inspected. The officers also review the building’s structural integrity and M&E systems. If any issues are found, the developer must fix them before a second inspection.

This stage can take anywhere from two to six weeks. Delays are not uncommon, especially if the developer needs to rectify multiple defects. The project sales team at The Hill at One North should keep you informed of the progress.

Step 3: Receiving the TOP and Key Collection

Once BCA issues the TOP, the developer will send you a formal notice. This notice usually includes the date when keys will be available for collection. You may also receive details about the defect liability period (DLP).

The DLP typically lasts 12 months from the date of TOP. During this period, the developer is responsible for fixing any structural or workmanship defects that appear. You should report any issues in writing as soon as you spot them.

Key collection is a straightforward process. You will sign the necessary documents, make any outstanding payment, and receive your key fobs and access cards. After that, you can start moving in.

What to Look For During Your Defect Walkthrough

The defect walkthrough is your most important inspection. It happens after TOP but before you move in. You should take it seriously.

Here is a checklist of areas to examine.

Area to inspect	What to look for	Common issues
Walls and ceilings	Cracks, uneven paint, damp spots	Hairline cracks, blistering paint
Flooring	Tiles or timber that are loose, chipped, or uneven	Hollow sounding tiles, scratched surfaces
Windows and doors	Smooth operation, proper sealing, no gaps	Sticking frames, broken handles, air leaks
Kitchen cabinets	Doors that close properly, no water damage	Misaligned hinges, swollen particle board
Bathroom fittings	Toilet flush, shower pressure, basin drainage	Slow drains, leaking pipes, cracked tiles
Electrical points	All sockets and switches work	Loose fittings, missing covers, no power
Air conditioning	Cooling function, remote control operation	Weak airflow, unusual noises, leaking units

Take your time. Bring a notebook and a camera. Do not be shy about pointing out problems. The developer’s representative will note them down and arrange for rectification.

Expert advice: Hire a professional inspector for your defect walkthrough. They have the tools to detect issues you might miss, such as moisture behind walls or electrical faults. The cost is small compared to the peace of mind it gives you.

Common Mistakes Buyers Make During the TOP Process

Many first time buyers rush through the process. They want to move in as soon as possible. But skipping steps can lead to headaches later.

Here are three mistakes to avoid.

1. Not attending the pre-TOP inspection. Some buyers think it is optional. It is not. This is your only chance to see the unit before the developer finishes all the touch ups. Missing it means you lose the opportunity to flag early issues.

2. Signing off on defects too quickly. The defect walkthrough can feel overwhelming. You may be eager to collect your keys. But signing the handover form without thoroughly checking the unit means you accept the condition as is. Always insist on fixing major defects before you sign.

3. Ignoring the defect liability period. After you move in, things can go wrong. A pipe may leak. A cabinet door may come loose. You have 12 months to report these issues. Do not assume they are your responsibility. Send a clear written report to the developer.

How to Prepare Financially for TOP

Receiving TOP triggers several financial obligations. You need to be ready.

• Final payment: You must pay the remaining balance of the purchase price. This includes any outstanding amounts from your progress payment schedule.
• Stamp duty and legal fees: These are usually settled before TOP, but double check with your lawyer.
• Moving costs: Engage a mover early. Prices can spike near the end of the month or during peak periods.
• Renovation budget: Even new units may need minor touch ups. Set aside a contingency fund of at least 5% of your renovation budget.

If you are using a home loan, your bank will disburse the final instalment upon TOP. Make sure your loan is in order. A delay in payment can postpone your key collection.

What Happens After You Get Your Keys

Once you have the keys, the real fun begins. You can start moving in furniture and setting up your home. But there are a few practical steps to take.

• Change the locks. Even though the unit is new, the developer and contractors have copies. Rekeying or installing a digital lock gives you peace of mind.
• Check the water heater and air conditioning. Run them for a few hours to ensure they work properly.
• Clean thoroughly. Construction dust can settle in every corner. A professional cleaning service is worth the expense.
• Register with the management corporation. You will need to pay monthly maintenance fees and follow the condo rules.
