Not every internal renovation in Dubai needs a building permit — but more do than owners assume, and getting it wrong risks a stop-work order. As a rule, works that move or remove walls, relocate wet areas, change MEP routes or touch the structure need approval; purely cosmetic works like painting, tiling and like-for-like replacements usually do not — though your community or building may still require an NOC. On the mainland modifications run through Dubai Municipality's Build in Dubai portal, in DDA zones via a Building Modification Permit, and in Nakheel and Palm communities through Trakhees. The Property Masters confirms whether your works need a permit and manages the submission. We are the approvals-management service — the authority issues the permit.
When an Internal Modification Needs a Permit
The dividing line is whether the works touch the structure, the layout, the wet areas or the building services. As a general guide, a permit is needed when you:
- Move or remove internal walls — changing the layout of the unit.
- Touch a structural wall, column or slab — anything load-bearing always needs engineering approval.
- Relocate wet areas — moving a kitchen or bathroom changes the drainage and waterproofing.
- Change the MEP — re-routing electrical, HVAC, plumbing or fire systems.
By contrast, cosmetic works usually do not need a building permit, for example:
- Painting and decorating.
- Tiling and floor finishes (like-for-like).
- Replacing fittings like-for-like without moving services.
"Cosmetic" still may need a community NOC. Even when the authority does not require a permit, the building or community may still require its own NOC and approved contractor for internal works. We check both the authority threshold and the community rule before you start.
Which Authority (When a Permit Is Needed)
- Mainland Dubai → Dubai Municipality (DM), via the Build in Dubai portal.
- DDA free zones → a DDA Building Modification Permit.
- Nakheel / Palm / PCFC communities → Trakhees, with the community NOC first.
Where the works affect fire systems or means of escape, Dubai Civil Defence (DCD) fire approval also applies — see Civil Defence approval.
The Risk of Skipping Approval
Carrying out modifiable works without the required permit carries real risk. The authority can issue a stop-work order and apply penalties, and unpermitted structural or wet-area changes can complicate a later sale, valuation or insurance claim. We do not publish specific fine figures — they are set by the authority and change — but the principle is firm: confirm the permit position before works begin, not after.
What the Submission Has to Address
When a permit is needed, the submission generally covers:
- Existing and proposed layout drawings showing what changes.
- Structural drawings where any load-bearing element is affected, stamped by a registered engineer.
- MEP drawings where services move, including fire in DCD format where relevant.
- Tenancy / ownership documents and the building or community NOC.
Timelines & Fees
Modification fees and timelines depend on the authority and the scope of the works, and they are not published as a single fixed figure (in DDA zones, a Building Modification Permit is involved). Community deposits vary by community — we confirm the figure with your building. For everything else, fees and timelines vary — we confirm the current figures for your specific modification.
We also carry out the works
We are a licensed fit-out contractor as well as an approvals-management service, so the same company that submits this application can deliver the project it covers:

Frequently Asked Questions
Does every internal renovation need a permit in Dubai?
No, but more do than owners assume. Works that move or remove walls, touch a structural element, relocate wet areas like kitchens or bathrooms, or change the MEP generally need a permit. Purely cosmetic works such as painting, tiling and like-for-like fitting replacements usually do not — though your building or community may still require its own NOC.
Which cosmetic works usually don't need a building permit?
Painting and decorating, like-for-like tiling and floor finishes, and replacing fittings like-for-like without moving services usually do not need a building permit. However, even for these the building or community may still require an NOC and an approved contractor, so we check both the authority threshold and the community rule before you start.
What happens if I modify without approval?
The authority can issue a stop-work order and apply penalties, and unpermitted structural or wet-area changes can complicate a later sale, valuation or insurance claim. We don't publish specific fine figures because they are set by the authority and change, but the safe approach is to confirm the permit position before works begin, not after.
Who approves internal modifications?
It depends on where the unit sits. On the mainland it is Dubai Municipality via the Build in Dubai portal; in a DDA free zone it is a DDA Building Modification Permit; in Nakheel and Palm communities it is Trakhees with the community NOC first. Where fire systems or escape routes are affected, Dubai Civil Defence approval also applies.
Do I need a community NOC for internal works?
Often, yes. Even when the authority does not require a building permit for cosmetic works, the building or community may still require its own NOC and an approved contractor for any internal works. We confirm the community's rule alongside the authority's permit threshold so nothing is missed.
