Renovating an older villa
If your villa was built twenty or more years ago — much of Jumeirah, Umm Suqeim and the early phases of the golf and ranch communities — something changed this year that most owners have not heard about yet, and it lands at exactly the moment you would be planning a renovation anyway.
The Quality and Safety Certificate
Law No. 3 of 2026 introduces a Quality and Safety Certificate for buildings twenty years old or more. The owner applies through the digital window, naming an engineering firm, which inspects the structure and reports on structural integrity, external cladding, external and common-area electrical and mechanical installations, windows, doors and barriers, Civil Defence compliance and CCTV requirements. The report is due within six months of initial approval, extendable to two years on request.
Read that list again with a renovation in mind. Structure, cladding, electrical, mechanical, windows and doors — it is very nearly the same list a full renovation opens up. Doing the inspection and the renovation as two separate exercises a year apart means paying twice for the same access.
What twenty years does to a villa
Older villas in this market share a predictable set of problems, and none of them are visible at a viewing.
Cooling and electrical loads were sized for how houses were used two decades ago, before the kitchen had three appliances that draw properly and before every room had a screen in it. Waterproofing in wet areas has a service life, and it is usually shorter than the building. And the drawings on file describe the villa as it was approved, not as it was built — which is why demolition on an older villa reliably reveals a slab thicker than recorded or a service run nobody drew.
This is not an argument against buying an older villa. The plots are larger, the locations are established, and the built form is often more generous than what replaces it. It is an argument for spending properly on the survey before anyone quotes a price.
What the plot allows, before you plan an extension
Owners of older villas very often want more floor area, and this is where an early check saves months. On a private villa there is no maximum built-up area, but the setbacks on the planning map must be respected; roof-level construction is capped at 50% of the roof floor area, and total building height at 16 m.
Setbacks come from your plot, not from a rule of thumb: the Dubai Building Code is explicit that they follow the permitting authority’s requirements as recorded in the DCR or affection plan, and that those take precedence over the code’s own table. Annexes are treated separately — they may sit on the plot boundary, must keep 1.5 m from the main villa, may not exceed 60% of the main building’s gross area, and are capped at 5.5 m high.
And one definition that settles a recurring argument over quotations: an indoor pool counts towards built-up area, while uncovered landscaping, hardscape and lightweight shade structures such as pergolas do not.
Who regulates your villa may not be who you think
Not every Dubai villa answers to Dubai Municipality. Communities developed on land held by PCFC or Dubai World — Nakheel’s among them — are regulated by Trakhees under Decree No. 22 of 2009. There is no published map of which streets fall where, and anyone who hands you one has made it up: jurisdiction follows the landowner and master developer, not the postcode.
The difference is real. Dubai Municipality’s self-décor route is scoped to commercial, office and investment units, so a private villa falls outside it. Trakhees wrote its equivalent circular the other way round and applies it to residential units as well. Same renovation, two regulators, two answers — which is why the first question we ask is the community, not the wish list.
