Renovation Contractor in Sham Shui Po

Cosmetic work (painting, flooring, replacing fixtures in place) rarely needs a permit. Structural changes, wall removals, and significant plumbing or electrical alterations usually do, and rules in Sham Shui Po follow your national and local building codes. Ask the contractor to name the specific approval needed and who applies for it — a contractor who suggests skipping permits is transferring the legal risk to you.

Manage trades yourself only if the job involves one or two trades and you can be on site regularly. Once a project needs sequencing (demolition, then rough plumbing and wiring, then walls, then finishes), a contractor typically saves more in avoided rework and delays than their 10-20% management margin costs.

Hold back 10-15% of the contract value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp. Do not tell the contractor your contingency figure — it is your buffer, not extra scope budget.

Ask every contractor to break the quote into the same line items: demolition, structural, plumbing, electrical, walls and finishes, fixtures, and a stated allowance for materials you choose. Then compare line by line. A single lump-sum number cannot be compared and cannot be enforced when scope questions come up mid-project.

Budget renovations run roughly HK$300-500 per square foot, mid-range HK$600-1,000, and designer/luxury work HK$1,200+. A typical 400-500 sq ft flat therefore lands around HK$250,000-400,000 for a full mid-range renovation.

Almost every building requires you to notify management, pay a refundable renovation deposit, and keep noisy works within permitted weekday hours. Separately, structural alterations and drainage works fall under the Buildings Department's minor works regime and need registered contractors — your contractor should identify which items on your scope are controlled.
