When you buy a flat that isn't built yet, the completion date in the brochure is the one number you're relying on most. The official records show how often it slips.
The Gulmohar Atlas collects project records from five state RERA portals, 20,985 projects in all. Of the projects still listed as active, the share whose registered completion date has already passed, as of 11 October 2026:
Share of active projects with a completion date on file, as of 11 October 2026 (Noida 969 projects, Bengaluru 4,089, Mumbai MMR 6,277, Gurgaon 852). A signal to check, not proof of delay: portals may not show extensions or completion. Source: Gulmohar Atlas, October 2026.
In Noida, 72.4% of the 969 active projects with a completion date on file are past it. In Bengaluru it's 69.4% of 4,089.
Read this carefully. A past date on the register doesn't prove a project is late. Some will have finished and not had their record updated, and some will have approved extensions the portal doesn't display. But it does mean the date on the register can't be taken at face value. You need to check what's actually happening.
What "delayed" and "stalled" mean
These are different problems:
- Delayed: the project is being built, just behind its committed date. You get the flat late.
- Stalled: construction has stopped, often because of money problems, disputes or insolvency. You may not get the flat for years, if at all.
The best-known count is Anarock's. In May 2022 it found about 4.8 lakh homes worth ₹4.48 lakh crore stuck or delayed across seven major cities, in projects launched in 2014 or earlier, with 2.41 lakh of them in Delhi-NCR and 1.29 lakh in the Mumbai region. That count covers older projects only, so it shows the scale of the problem, not the odds for a project launched today.
The registers also show projects already in serious trouble. On UP-RERA, 166 Noida projects carry an NCLT (insolvency) status.
Step 1: verify the right entity and project
- Search your state's RERA portal using the registration number from the sale agreement, not the project's marketing name.
- Check that the promoter's legal name on the portal matches the company on your agreement and payment receipts.
- Check the phase or tower. Large projects are often registered in phases with different completion dates.
- Note the registered completion date and any extensions shown, and ask the developer in writing about any extension.
Our RERA guide walks through the portals.
Step 2: check the developer's past delivery
A developer's history is the best evidence you have:
- Search the portal for the promoter's other projects and pick at least three that should be finished.
- For each, compare the completion date they registered with when the occupancy or completion certificate was actually issued. Ask the local authority, or residents of the finished project.
- Look for a pattern. One late project can have a good reason. Repeated large gaps are a warning.
This won't predict exactly what happens next. It tells you whether this developer's dates have been reliable before.
Step 3: read complaints in context
Most portals show complaints and orders against a project. Count them, then read them:
- What are they about? Delayed possession, refunds or construction quality.
- How recent are they, and has the regulator issued orders?
- Has the developer complied with those orders?
There is no reliable rule like "more than X complaints means avoid". A small project with one serious order may be riskier than a large one with many minor complaints. If a record isn't available, treat it as unknown, not as clean.
Step 4: budget for a delay before you commit
If you're renting while you wait, a delay means paying rent longer, plus interest on whatever the bank has already disbursed. In our worked example, a ₹1.2 crore flat with a ₹90 lakh loan and ₹25,000 a month rent:
Illustration (model uc-vs-rtm@1): ₹1.2 crore flat, ₹90 lakh loan at 9% drawn over 36 months, ₹25,000 a month rent until possession. Extra rent is ₹1.5, ₹3.0 and ₹6.0 lakh; extra interest is only ₹0.1–0.3 lakh, because after possession you'd pay EMI interest anyway. Illustration — inputs are stated in the text.
Almost all of that cost is rent. Ask yourself whether you could carry 12–24 extra months of rent alongside the pre-EMI without strain, and keep the reserve to do it. For the full comparison with buying ready-to-move, see under-construction vs ready-to-move.
If you're already in a delayed project
Keep every payment record, letter and email. Check the project's RERA page for revised dates and orders. Talk to other buyers in the project. A local property lawyer can tell you what remedies apply under your state's RERA rules. We don't give legal advice on specific cases. A Gulmohar evaluation reads the project's RERA status and completion date when you pick it from our registry, but it doesn't check court records or orders.
Common questions
How do I check a builder's delivery record?
On your state's RERA portal, search the promoter's legal name rather than the project's marketing name. For at least three past projects, compare the completion date they registered with the date the occupancy or completion certificate was actually issued, which you can confirm with the local authority or with residents. A pattern of large gaps matters more than one late project.
Does RERA registration guarantee on-time possession?
No. Registration shows the project is registered with the state authority and carries a declared completion date, but it doesn't guarantee delivery. In the Gulmohar Atlas, 72% of Noida projects and 69% of Bengaluru projects still listed as active had passed their registered completion date as of October 2026.
How should I budget for a construction delay?
Work out what you'd keep paying each month until possession: mainly rent, plus interest on what has been disbursed. In our worked example, that's about ₹25,000 a month, or ₹3.2 lakh for a one-year delay and ₹6.3 lakh for two years. Make sure you could carry that without strain, and keep the reserve to do it.
