After the drawings are approved or the permit is issued, your wishes may change: an extra room, moving the kitchen, changing the facade, or a larger annex. This is normal in building projects that last months. But the key question is: does the change need re-approval? A wrong answer can mean a building that differs from its permit, and a problem that surfaces at the occupancy certificate or sale. This guide explains the general rule, examples of each type of change, the requirements of the add and modify building components service, the difference between changing before and after the permit, and why you should not change things on site directly.
The General Rule
If the change alters the building components in the permit (adding, removing or modifying a component, or changing areas, floors or use), it needs a regulatory route. Balady states that changes to a building permit after issue, such as adding a floor or removing an annex, are made through the add and modify building components service.
Examples
| Change | Likely route |
|---|---|
| Changing the internal layout without affecting areas or structural elements | Amending the construction drawings with the office, which decides whether it affects the approved set |
| Adding a room, annex or floor | Add and modify building components |
| Changing the use | Depends on the requirements, usually modifying components |
| Changing the facade design | Depends on the scope of change and identity requirements |
| Enlarging openings or removing load-bearing walls | Needs a structural study and a regulatory route |
For adding annexes and floors read: Adding an annex or rooftop room and Structural assessment for an additional floor.
Requirements of the Add and Modify Building Components Service
- Contracting an engineering office.
- Paying the service fee.
- An existing building permit.
See our addition and modification permit service, and read: Modifying building components.
Before or After the Permit?
| Timing | What happens | Ease |
|---|---|---|
| During design | The office amends the drawings directly | Easiest and cheapest |
| During review | The change is included in the response to comments | Easy, with possible delay |
| After the permit is issued | The add and modify building components service | Needs a procedure and fees |
| After construction without amendment | Status correction, and fines may apply | Hardest |
Why Not Change Things on Site Directly?
Because construction that departs from the drawings surfaces at the occupancy certificate, complicates sale, and may expose you to fines. Read: Made changes without amending the drawings? and Reasons the occupancy certificate is rejected.
Tips to Reduce Changes
- Use 3D design before approval.
- Discuss future needs early.
- Have the supervisor document any on-site change request and refer it to the office.
Frequently Asked Questions
Can I make changes before the permit is issued?
Yes, changing before issue is easier; the office amends it within the review round.
Do the structural drawings need amending too?
If the change affects elements or loads, yes.
Does changing colours and finishes need a permit?
Interior finishes usually do not, but the facade may be subject to urban identity requirements. Read: The facade renovation permit.
Who is responsible for an unapproved change?
The owner, contractor and supervisor, each according to their role. Read: Supervisor and contractor responsibility.
How long does modifying the permit take?
It depends on the scope of the change, the quality of the drawings and review rounds.
