Before a consultant spends weeks on a full drawing set, it is worth knowing whether Dubai Municipality will accept the basic design. That is what the preliminary approval, also called the initial design concept approval, is for. It is optional, inexpensive and fast to apply for, and it can save a project from a full redesign later.
This guide explains what Dubai Municipality's preliminary approval is, when it is worth applying for, the documents and fees involved, and how it fits into the wider permit process for new buildings, additions and modifications on the Dubai mainland.
For help preparing and submitting your design, see our Dubai Municipality approval services.
The short answer
Dubai Municipality's preliminary approval is an early review of the architectural design against building codes and planning standards, before the final design is prepared. A building consultant applies through the Build in Dubai platform with the architectural drawings, or for additions and modifications, the approved and proposed drawings. The fee is AED 100 to AED 250 plus a AED 20 Knowledge and Innovation fee. The approval is optional, and it does not allow construction to start; a building permit is still required.
What preliminary approval does and doesn't do
Preliminary approval answers one question early: is the concept acceptable in principle? Dubai Municipality checks the proposed architecture against the planning rules and building codes that apply to the plot, such as land use, setbacks, height, coverage and parking.
It does not:
- Allow any work to start on site.
- Replace the building permit, which still needs full architectural, structural and MEP drawings and other entities' NOCs.
- Guarantee approval of the final design if it changes from the approved concept.
Think of it as a planning check that reduces the risk of the full submission, not as a permit.
Which projects can use preliminary approval
Dubai Municipality offers initial design approval for:
- New buildings, including villas, investment villas, multi-storey buildings and buildings developed under a floor area ratio.
- Additions and modifications to existing buildings.
Because it is optional, you can apply directly for a building permit or modification permit instead. Our Dubai Municipality approval process guide explains the full permit route.
When it is worth applying
Preliminary approval is most useful when there is real planning risk in the concept. Typical cases include:
- Plots with tight setbacks or unusual shapes, where the buildable area is not obvious.
- Designs that push height, coverage or floor area limits.
- Extensions to older villas, where the existing building may not match current rules.
- Mixed or unusual uses, where the permitted use on the affection plan is open to interpretation.
- Larger buildings, where a redesign after detailed engineering would be expensive.
For a simple, code-compliant villa or a small modification with clear rules, many consultants go straight to the permit.
Documents for preliminary approval
New buildings
- Architectural drawings of the proposed building: site plan, floor plans, sections and elevations.
- Supporting plot documents, such as the affection plan and ownership documents, as the platform requires.
Additions and modifications
- The approved (licensed) drawing, with the area to be modified highlighted in yellow.
- The proposed drawing, with the proposed change highlighted in red.
Clear marking of what changes is the most important thing in a modification submission. Reviewers compare the two drawings directly.
The preliminary approval process, step by step
- Log in to the Build in Dubai platform. The building consultant applies; owners do not submit directly.
- Upload the drawings and supporting documents.
- Submit and pay the fee.
- Receive Dubai Municipality's response. The application is approved, rejected, or returned for consultation and revision.
- Develop the final design. Use the approved concept and any comments as the basis for the full permit submission.
Fees
Dubai Municipality's initial design approval fees, as published, are:
- Villa, investment villa or building up to 7 floors: AED 100 plus AED 20 = AED 120.
- Building over 7 floors: AED 150 plus AED 20 = AED 170.
- Floor area ratio building: AED 250 plus AED 20 = AED 270.
- Modification or addition (all types): AED 100 plus AED 20 = AED 120.
The AED 20 is the Knowledge and Innovation fee. Payment can be made through Dubai Municipality's channels, including the DM app, DubaiNow and the Dubai Smart Government portal.
How preliminary approval fits into the full process
- Plot checks: affection plan and, in master communities, the developer NOC.
- Preliminary approval (optional): concept check against planning rules.
- Full design: architectural, structural, MEP and fire and life safety drawings.
- Building permit: submitted online, with other entities' NOCs added in the same application.
- Inspections: structural inspections during construction.
- Completion certificate: after the final joint inspection.
For villas, see our guide to DM villa building permits and completion certificates. For how residential and commercial routes differ, read commercial vs residential DM approval.
Common reasons preliminary designs are returned
- Setback or height breaches against the affection plan.
- Built-up area over the permitted limit, often from counting rules for balconies, basements or roof structures.
- Parking below the requirement for the use and size.
- Use not permitted on the plot.
- Unclear modification drawings that don't show what is existing and what is proposed.
Our guide to architectural design mistakes that cause approval delays covers these in more depth.
Preliminary approval in other jurisdictions
If your plot isn't on the mainland, the equivalent step sits with another authority. The Dubai Development Authority, for example, has its own preliminary design approval with a published 5-working-day estimate; see our DDA preliminary design approval guide. Trakhees issues a concept design NOC; see how to get Trakhees approval.
Preliminary approval vs building permit: a side-by-side view
- Purpose: preliminary approval checks the concept against planning rules; the building permit authorises construction.
- Drawings: preliminary needs architectural drawings only; the permit needs architecture, structure, MEP, insulation, drainage and fire and life safety.
- Other entities: preliminary is a Dubai Municipality review; the permit collects NOCs from DEWA, RTA, Civil Defence and others in the same application.
- Fee: preliminary is a flat AED 100 to AED 250 plus AED 20; the permit fee is calculated on area and component rates.
- Outcome: preliminary gives approval in principle; the permit gives stamped drawings you can build from.
The two steps answer different questions. A consultant who uses preliminary approval well treats it as a filter: only concepts that pass go on to detailed engineering, so structural and MEP effort is never spent on a layout that planning will not accept.
How to read Dubai Municipality's comments
A returned preliminary application usually comes back with comments tied to specific rules. Read them in three groups:
- Hard planning limits, such as setbacks, height, built-up area and permitted use. These need a design change; there is rarely room for argument.
- Calculation questions, such as how balconies, roof structures, basements or service areas were counted. These are often resolved with a clearer area statement rather than a redesign.
- Drawing clarity, such as missing dimensions, unclear marking of existing and proposed work, or an inconsistent site plan. These are fixed by improving the drawing set.
Respond to each comment directly on the revised drawings and keep a short response sheet. It speeds up the second review and shows the reviewer that every point was addressed.
Preliminary approval for villa extensions and older buildings
Extensions are where preliminary approval earns its fee. Older villas were often permitted under earlier rules, and some have unapproved additions such as enclosed terraces, roof rooms or service blocks. Before designing the extension, compare the latest approved drawings with the building as it stands. If the two differ, the existing differences may need to be regularised before or alongside the new work.
A preliminary submission with the approved drawing marked in yellow and the proposed change in red gives Dubai Municipality a clear picture early, and tells you whether the extension is feasible before the owner commits to a contractor. Our villa renovation process guide explains how extension, modification and decoration routes differ.
A pre-submission checklist
- Confirm the affection plan is current and matches the owner and plot number.
- Check permitted use, height, setbacks and built-up area before massing.
- Prepare a clear area statement showing how each space is counted.
- Show parking provision against the requirement for the use.
- For modifications, mark existing work in yellow and proposed work in red.
- Get the developer NOC first in master communities.
- Agree the scope and budget of the full design with the owner, so the approved concept can move straight to permit stage.
