UDCPR swept the previous rulebooks away on the day it commenced. It did not sweep away the permissions those rulebooks had already granted.

The short answer. Chapter 1, Regulation 1.5, UDCPR as updated 30 January 2025** preserves any development permission granted, and any development proposal on which action was taken, under the erstwhile regulations. Those remain valid unless UDCPR specifies otherwise. The owner may carry on developing exactly as approved, and for that limited purpose the old regulations stay in force. The protection is not unlimited: an unstarted permission must be renewed within its one year validity, and renewals cannot run beyond three years.

Note

Chapter 1, Regulation 1.2, UDCPR as updated 30 January 2025 is the other half of the picture. UDCPR came into force from the date of publication of the notification in the Official Gazette, and on that date all Development Control Regulations and special Regulations then in operation ceased to operate. Regulation 1.5 is what stops that ending reaching backwards into permissions already issued.

What the regulation says

Three protections sit in Chapter 1, Regulation 1.5**, and they do different jobs.

A granted permission survives. Notwithstanding anything in UDCPR, a permission granted under the erstwhile regulations is valid and continues to be valid.

So does a proposal that had progressed. The regulation defines "action taken" to include the issuance of a letter for payment of Development and other Charges after approval of the proposal in principle. A file that had reached that stage is inside the protection, not outside it.

The owner may finish under the old code. It is permissible for the owner to continue developing the project as approved under the erstwhile regulations in full, and the regulation states that for that limited purpose the erstwhile regulation shall remain in force.

The clock, which is the part people miss

How long a pre-UDCPR permission survives if work has not commenced

Banded by time from issue

  1. Within 1 yearThe original validity period. Work commenced, or the permission renewed in time, and the protection holds.
  2. Not renewed in timeThe development permission is deemed to have lapsedThe trigger is expiry of the one year validity without renewal
  3. Renewed, year to yearPermitted. There is no bar to further renewing a valid permission annually.
  4. Beyond 3 yearsNot available. The extended period shall in no case exceed three years.

So the savings clause is a bridge with a length, not a permanent exemption. A permission issued before commencement, never acted on and never renewed, lapses. One renewed diligently still runs out of road at three years.

What changes this answer

  • Whether action was taken. A proposal that reached the charges letter after in-principle approval is protected; one that did not is not.
  • Whether work commenced. The lapse provision is framed around work not being commenced within the validity period.
  • COVID-era proposals. Chapter 1, Regulation 1.5** carries specific transitional provisions for proposals that could not be sanctioned because of the pandemic, including a disposal deadline of 31 January 2022, after which applicants had to submit fresh proposals under UDCPR.
  • What the current regulations say instead. The protection runs "unless otherwise specified in these regulations", so a provision of UDCPR that speaks directly to the point can displace it.

Chapter 1, Regulation 1.4, Applicability of Regulations, sub-clause (vii), is the companion protection and it is broader in one way. Nothing in UDCPR requires the removal, alteration or abandonment of a lawfully established existing use or occupancy, or prevents it continuing. The exception is where the Authority considers the building unsafe or a hazard to adjacent property. Lawful existing use is protected; danger is not.

What this does not tell you

Which code applies to a parcel with no permission yet is a different question, answered by the applicability map and by who the Authority is for that area. And a permission's date does not tell you what was actually built under it, which is a filings question.
