The short answer
Dubai Hills is one of the communities where the Dubai Development Authority (DDA) is the building authority, and Emaar is the master developer. A renovation that changes walls, services, layout or external appearance usually needs a modification permit from DDA, with an Emaar NOC first.
Two layers of approval
The Dubai Development Authority is the building authority for Dubai Hills, alongside communities such as Arabian Ranches, Al Barari, La Mer and City Walk. Emaar is the master developer. Both can have a say over the same works on the same villa, and meeting one does not discharge the other.
Even in a well-known community, read your own paperwork. Which authority approves your project depends on the community and zone your plot sits in, and it's confirmed from your plot documents.
Which works need approval
The test is what the work changes, not what it costs. Anything that affects walls, services, layout or external appearance needs a modification permit. In Dubai Hills, the items that most often cross that line are:
- Opening up the ground floor by removing or relocating walls.
- Moving a kitchen, a bathroom or a laundry, which moves drainage and supply runs.
- New or enlarged openings onto the garden.
- Pergolas, shade structures, outdoor kitchens and other additions visible from outside.
- Extensions of any kind, which change the envelope.
New finishes on the same layout and services are cosmetic. For the borderline cases, see do you need a permit to renovate your villa.
Where the Emaar NOC fits
In most master-developer communities, the master developer's No Objection Certificate is needed before drawings go to the building authority. It is most likely to matter for external changes and anything visible from the street or shared areas, because that is where the community's appearance is protected.
Treat the NOC as its own approval with its own drawings and comments. Emaar's design guidelines for the community shape what the NOC will accept, so they belong in the concept, not at submission. Our guide to master developer design guidelines explains why.
What to gather before design starts
- The title deed and plot documents.
- The approved drawings and any as-built layouts, so changes can be shown against what exists.
- The current Emaar design guidelines for your villa type.
- A plain list of what you want to change, room by room and outside.
If the villa has been altered since handover, find out whether those changes were approved. Unrecorded works affect what a new submission can achieve. Buying a villa to renovate covers the checks.
Who handles the submissions
The Architect of Record prepares, stamps and submits the drawings, obtains the Emaar NOC, answers the comments from Emaar and DDA, and keeps the approved set aligned with what is built. When the same studio designs the renovation and holds the AOR role, the drawings the authority reviews are the drawings that reach site.
At Ganggaan, design, Architect of Record permitting, FF&E sourcing and site supervision sit in one studio. Ganggaan prequalifies, tenders and supervises the contractor; it does not build the villa itself.
Before you call a contractor
- Confirm the authority and the master developer from your plot documents.
- Classify every item in the scope against walls, services, layout and external appearance.
- Bring the Architect of Record in at concept stage.
- Ask contractors to price only once the scope is approvable.
