Drawings & design · Existing buildings
When the drawings on file don't match what is actually standing, every later approval gets harder. We measure the property, draw it as it really is, compare it with the approved set and plan the route to completion, a new permit or regularisation.
An approved drawing records what the authority agreed to. An as-built drawing records what was actually built. In a perfect project they are the same. In practice, Dubai has many villas, shops and warehouses where the two drifted apart years ago, and the gap only surfaces when someone needs a new permit, a completion certificate or a clean sale.
As-built work has two quite different uses. On a project that has just finished, it is the record set the contractor and consultant hand over at completion, showing the final positions of walls, openings, services and levels. On an older property, it is the starting point for any new application: you can't design a modification, assess a structure or regularise an extension without an accurate picture of what exists today.
We survey the property, prepare the drawings and compare them against whatever approved records exist. Where differences need authority action, we explain the options and coordinate the application. The authority, and where relevant the master developer, decides whether to accept the works as built.
Older villas and units often changed hands without the approved set. Before any new permit, the consultant needs a reliable base drawing, and an as-built survey is the quickest way to get one.
A previous owner enclosed a terrace, added a room on the roof or moved the kitchen. Those changes need to be documented before anything else can be approved.
Completion inspections check that what was built follows the permit. Final records of the building and its services are part of a tidy handover and of the completion file.
Buyers, banks and tenants increasingly ask whether the built-up area and layout match the approvals. Knowing the answer before they ask puts you in control of the timeline.
As-built drawings are also the first step for a structural evaluation of an existing building and for most change-of-use applications, since both start from the building as it stands.
Each permit authority handles completion and after-the-fact changes in its own way. A few examples from their published material show why the as-built record matters:
| Authority | What it publishes | Why it matters for as-built work |
|---|---|---|
| Dubai Municipality | Building Completion Certificate services, including a route to obtain the certificate without the original contractor's or consultant's approval (listed at 7 working days), and a service to request a visit verifying that building violations have been corrected | Owners whose consultant or contractor has left the project, or who have violations to close, need accurate drawings of the current condition |
| Dubai Development Authority | A Third Party Building Survey by a Dubai Land Department-registered surveyor, mandatory before a completion certificate for buildings other than villas. DDA lists no service fee and 5 working days for feedback. | The survey submission includes CAD drawings, a polyline diagram and a coloured area diagram, so it relies on a precise as-built geometry |
| Trakhees (PCFC) | Circular No. 2 of 2025: after a completion certificate, extensions and minor structural modifications to existing facilities need a Modification NOC regardless of area, followed by a Modification Completion Certificate | Unapproved changes after completion have to be shown against the completed building to be assessed |
In master communities, the developer also keeps a record of what it approved. Developers such as Nakheel and Emaar expect alterations to go through their NOC process, so a regularisation usually involves the developer as well as the permit authority.
Enforcement is active. Dubai Municipality reported that since the start of 2026 its field teams had carried out more than 16,000 inspection visits in residential areas and recorded 2,395 violations. Construction works or alterations without the required permits were among the most prominent.
We scale the survey to the purpose. A one-bedroom apartment for a decoration permit needs less than a G+1 villa with an unapproved roof extension. A full set typically contains:
Where a DLD-registered surveyor's report is required, as in DDA's third-party building survey, we coordinate that surveyor's input with our drawings so the figures agree.
Title deed, site plan, any approved drawings, previous permits and NOCs, and the completion certificate if one was issued. Gaps in this file are noted.
Owner · our team
Our team visits, measures every level and the plot, photographs the building and records visible structural and services elements.
Our survey team
We produce the as-built set and compare it with the approved drawings. Each difference is classed: minor and within the approvals, needing a modification approval, or needing structural review.
Our team
You get a short report setting out the options: accept the property as it is, apply to regularise specific works, remove or modify works that can't be approved, or combine regularisation with a new project.
Our team · owner decides
Where regularisation is chosen, we prepare the drawings and supporting documents for the developer NOC and the permit authority, with structural and MEP input where needed, coordinated through a registered consultant where required.
Consultant · developer · authority
The authority inspects. Any required remedial works are completed by a licensed contractor, and the file is closed with the relevant completion or modification certificate.
Authority · contractor
Our survey and drawing fee depends mainly on:
Authority and developer charges for regularisation are separate and depend on the authority and the works. Under Local Order No. 3 of 1999, construction without a permit can bring fines of up to AED 50,000, doubled for a repeat, alongside remedial costs. We will not estimate a penalty we can't confirm. We tell you which charges to expect and confirm them with the authority.
For a wider view of what happens at the end of a project, read our guide to the building completion certificate.
Approved drawings show the design the authority permitted. As-built drawings show the property as it was actually built or as it stands today, based on measurement. Comparing the two shows whether any works need approval.
Often, if they meet the current rules and the structure is adequate. Some works can't be approved and must be modified or removed. The developer and the permit authority decide, and the route differs between authorities.
For some services, yes. For example, DDA's third-party building survey before a completion certificate must be carried out by a surveyor registered with the Dubai Land Department, though villas are excluded. For most design and regularisation work, a consultant's measured as-built survey is the starting point.
Sometimes copies can be requested from the authority or the developer through the owner's account. Where they can't be found, or don't match the villa, an as-built survey gives you a reliable record for the future.
Site measurement depends on the size of the property and on access, and we give you a programme once we have seen the floor area and the records. Drawing and comparison time depends on size and on the records available. Any regularisation application that follows has its own authority timeline.
