Building & renovation: say what exactly you’re looking for

Building & renovation in Hong Kong

Updated 4 November 2026

A renovation in Hong Kong usually costs about HK$1,000 per square foot on average, with most quoted jobs between HK$600 and HK$1,400 per square foot, according to sellers' websites. Office refreshes and fit-outs are priced lower per square foot, and small flats are often quoted as one total. The quickest way to current prices for your flat or office is a request on BlaBlaPrice.

Permits and approvals

Most interior alterations in Hong Kong need government approval under the Buildings Ordinance, and minor works permits are often part of the job. One seller's guide budgets HK$15,000–50,000 for these approvals, so ask whether your quote includes them. Some projects also need specific licences before groundwork can start, and the fees differ from job to job, so get them named in writing before you sign.

Season and timing

Hong Kong's summer runs from June to August and its winter from December to February, with November sitting between the two. Painting, sealing and finishing work suits the cooler months, so a request in November gives you time to plan the work for winter. Schedule the noisiest stage, such as hacking out tiles or moving pipework, early in the programme, so that the finishing work can follow.

How renovation is quoted here

Flats and offices in Hong Kong are quoted per square foot, so measure the floor area in sq ft rather than square metres, and state the district. A full-gut renovation runs from HK$600 to HK$1,400 per sq ft, while an office refresh is HK$300–500, so tell the seller which scope you mean. Ask whether the price includes materials as well as labour.

What to put in your request

Describe the scope of work in your own words: which rooms, which trades and what must be removed. Add the floor area in square feet, the district (Central, Kowloon, Sha Tin, Tsuen Wan or Tuen Mun), whether the flat is owned or rented, your deadline and your budget. A photo of the space helps sellers quote without a visit.
