5 Proven Steps for an Effective DDA Approval Process for Steel Structures, Pergolas & Outdoor Works
By Eng Amjed / November 4, 2025
The DDA approval process is a critical step before constructing any steel structure, pergola, or outdoor work in Dubai. Whether you are adding a shaded canopy, a steel mezzanine, or a decorative pergola to your villa or commercial property, the Dubai Development Authority (DDA) requires all such works to be structurally compliant, safe, and officially permitted. Understanding how to secure your DDA permit in Dubai efficiently ensures your design aligns with the Dubai Building Code (2021) and avoids costly project delays. In this comprehensive guide, we explain the five proven steps to obtain approvals for steel structures, pergolas, and outdoor works—from design preparation to final completion—based on DDA’s latest procedures and Structural Solutions’ on-ground experience.

How to get DDA approval for steel pergola outdoor structure in Dubai
Step 1 – Prepare Your Design & Documentation as per DDA Standards
The first step in the DDA approval process is preparing accurate and compliant documentation.
DDA enforces the Dubai Building Code 2021 (DBC 2021), which aligns with international standards such as ACI 318, ASCE 7-22, and AISC 360-16 for structural steel design.
Key documents required
- Architectural drawings – approved layout showing proposed modifications.
- Structural drawings – framing plan, foundation layout, details, and steel connection notes.
- Structural calculation report – signed and stamped by a licensed structural engineer.
- Material specifications – steel grade (e.g., S275 / S355), concrete strength, coating system.
- Site photographs and location plan – clearly showing existing and proposed conditions.
- Authority forms – DDA “Structural Submission Form” and “Application for Permit.”
💡 Tip: For pergolas and lightweight canopies, provide wind-load verification as per ASCE 7-22 (Chapter 26–30). DDA reviewers often request this even for small outdoor works.
Step 2 – Engage a Licensed Consultant & Structural Engineer
According to DDA regulations, submissions must be made by an authorized consultant.
You may appoint either:
- A registered consultancy under DDA, or
- A freelance structural engineer partnered with a licensed consultant (such as Structural Solutions / Nirvana AEC).
Roles and responsibilities
| Party | Responsibility |
|---|---|
| Consultant | Uploads applications to DDA portal, coordinates comments, and ensures compliance. |
| Structural Engineer | Designs members, prepares calculations, and confirms adequacy per DBC 2021. |
| Contractor | Executes fabrication and installation as per approved drawings. |
⚙️ Reference: DDA Portal – Building Permit Workflow
Working with a DDA-qualified consultant prevents submission rejection and speeds up approval. Structural Solutions has processed numerous permits for villa pergolas, outdoor canopies, and steel staircases under DDA jurisdiction.
Step 3 – Submit Online via the DDA Portal
Once drawings and reports are ready, the consultant submits them online through the DDA e-Services Portal.
Typical submission checklist
- Filled DDA application form (Project type: Steel Structure / Pergola / Outdoor Work).
- AutoCAD & PDF drawings.
- Stamped structural calculations PDF.
- Consultant trade license + Dubai Municipality registration.
- Owner’s Emirates ID + Title Deed copy.
- Payment voucher for application fees (usually AED 1,000–1,500).
After upload, DDA assigns a review engineer who checks structural adequacy, boundary setbacks, height limits, and material safety.
Common review comments
- Missing wind-load calculations.
- Insufficient connection details for base plates.
- Pergola height exceeding 2.5 m within setback areas.
- Missing contractor G+1 license copy for installation.
These comments must be addressed within 5–10 working days.
Step 4 – Respond to DDA Comments & Secure Final Approval
After the first review cycle, DDA issues an initial comment sheet through the portal.
How to handle comments effectively
- Reply using the official response template (
Response to DDA Comments.docx). - Revise drawings + calculations, highlighting all modifications in cloud bubbles.
- Upload revised set as “Revision 01 – Resubmission.”
- Include the consultant cover letter summarizing the responses.
DDA reviewers typically approve after one or two iterations when responses are clear and professionally formatted.
Final approval deliverables
Once approved, you will receive:
- DDA Approved Drawings (with QR code and official stamp).
- Structural NOC Letter for construction.
- DDA Permit Number for inspection tracking.
Step 5 – Execute Works, Site Inspection & Completion Certificate
After receiving approval, you may begin construction under your appointed G+1 contractor.
Site inspection requirements
- Notify DDA before starting fabrication.
- Keep approved drawings on site.
- DDA inspectors may verify foundation dimensions, anchor bolts, and steel sizes.
- Submit As-Built Drawings and photos after installation.
When the work passes inspection, DDA issues the Completion Certificate, officially closing the file.
✅ Compliance Reminder: Non-approved structures are subject to demolition and fines under DDA Circular No. (207/2023) – “Unauthorised Modifications Policy.”

Frequently Asked Questions
Q1: How long does the DDA approval process take for steel structures or pergolas?
A: It usually takes 10–15 working days for initial review and another 5–7 days for final approval, depending on project complexity and submission quality.
Q2: What is the difference between DDA and Dubai Municipality approval?
A: DDA applies to projects within its jurisdiction (e.g., Dubai Design District, Dubai Industrial City, Barsha South plots registered under DDA). Dubai Municipality (DM) covers other zones under its authority. Both follow the Dubai Building Code 2021.
Q3: Do I need a structural calculation report for a small pergola?
A: Yes. Even light structures require basic verification of member capacity and wind load resistance as per ASCE 7-22 Section 26–30. DDA does not accept unverified manual sketches.
Q4: Can a homeowner apply for DDA approval without a consultant?
A: No. Only registered consultants can upload drawings on the DDA portal. However, homeowners can work with freelance engineers through licensed consultancies like Structural Solutions / Nirvana AEC to save cost while remaining compliant.
Q5: What happens if I install a steel structure without DDA approval?
A: DDA may issue a violation notice, impose fines up to AED 50,000, and order removal of the unauthorized structure. A retrospective NOC may be possible only after submitting a full structural assessment.
