Authorities Made Easy: Building Permission and Land Conversion in Thane (2026 Guide)

Before you rely on any of this: rules, fees and portals change often. This guide was updated in October 2026 for Maharashtra's 2025 land revenue reform. UDCPR clauses below are from the official copy consolidated to 30 January 2025; later changes are notified separately. Confirm the current position with the authority, or an architect who has filed in your area recently, before you spend money. This is a plain-English guide, not legal advice.

Inside Thane city, building plans are approved by the Thane Municipal Corporation (TMC) under the state's Unified Development Control and Promotion Regulations (UDCPR), filed online by your architect. Thane also has rules that apply nowhere else, written into UDCPR itself, and a short drive in any direction puts you under a different authority. So two questions decide everything: who approves this survey number, and which Thane-only rules touch it?

If the land is still agricultural on paper, the 2025 reform means no separate NA permission from the Collector where the plan allows housing: the building permission does the conversion.

First question: which authority governs your plot?

"Thane" on a listing can mean the city, the district or just "near Thane". The authorities you are likely to meet:

Thane Municipal Corporation: plots inside TMC limits, where the Municipal Commissioner or his appointee is the "Authority" under UDCPR. TMC is listed among the live authorities on the state's Building Plan Management System (BPMS), and its own site is thanecity.gov.in.
The neighbouring corporations: Kalyan-Dombivli, Navi Mumbai, Mira-Bhayandar, Bhiwandi-Nizampur and Ulhasnagar are separate corporations, each listed separately on BPMS for Thane district. A plot in Dombivli or Mira Road is not a TMC file just because the address says Thane district.
MMRDA, in its notified areas: MMRDA prepares the Regional Plan for the Mumbai Metropolitan Region and is the Special Planning Authority for specific notified areas. One example in Thane district: the State appointed it SPA for the Bhiwandi Surrounding Notified Area by a notification of 17 March 2007, now 60 villages of Bhiwandi taluka.
The District Collector, in Regional Plan areas: where land sits outside every planning authority, UDCPR names the Collector as the Authority. The zoning there comes from the MMR Regional Plan 2016-36, which MMRDA says was sanctioned on 20 April 2021 and came into force on 20 June 2021.
MIDC and NAINA areas: UDCPR expressly does not apply to them, so their own regulations govern.

The rulebook: UDCPR, with a Thane chapter

Thane follows UDCPR, sanctioned by the State on 2 December 2020 and applicable to every planning authority and Regional Plan area in Maharashtra except Greater Mumbai and a short list of others, including MIDC, NAINA and JNPT. Mumbai's DCPR 2034 does not apply here; our Mumbai guide covers that rulebook. UDCPR has been modified dozens of times since 2020, so use the latest consolidated copy from the Directorate of Town Planning (currently updated to 30 January 2025) and ask your architect about anything notified since.

What generic Maharashtra guides miss is that UDCPR treats Thane differently in places (30 January 2025 copy):

Rule	What it says for Thane
Parking (Regulation 8.2.2)	TMC's multiplying factor for off-street parking is 1.00, the same as Pune. Other corporations in the MMR use 0.8, so a Thane building needs more parking than the same building in a neighbouring city. Redevelopment projects in TMC use 0.8.
Ancillary FSI premium (Regulation 6.1.1)	Charged at 15 per cent of the ready reckoner land rate in Pune and Thane, against 10 per cent in other MMR corporations.
Big roads (Regulation 10.2.2)	No construction within 7.5 m of the Eastern Express Highway or of roads wider than 52.5 m.
Air Force Station Thane (Regulation 10.2.5)	No construction, digging or tree planting within 100 m of the station boundary.
Defence establishment (Regulation 10.2.6)	Height limits in colour-coded zones around the unit in Kolshet, Kavesar and Waghbil, from nil near the boundary to 84 m further out.
Chemical zone (Regulation 10.2.4)	A 100 m green belt around hazardous chemical industries, then a 150 m low density zone limited to FSI 0.5 and ground plus two floors.
Small-plot redevelopment (Regulation 10.2.15)	On plots up to 1,500 sq m with buildings up to 24 m, the 6 m side and rear margin can be relaxed to 3 m in genuine hardship, subject to a fire NOC.

If your plot is near the highway, Kolshet or an industrial belt, read these clauses before design starts.

Thane's development plan: check the draft as well

The zoning of your survey number comes from TMC's development plan. According to TMC's commissioner, quoted by PTI in The Week on 14 October 2024, the original plan was approved in 1999 for 20 years, and the draft of the first revised plan was published that day for 60 days of suggestions and objections, to be heard by a government-appointed committee. As of October 2026 we could not find a notification sanctioning the revised plan, so treat it as a draft unless your architect shows you otherwise.

This matters more since the 2025 reform, because the new law accepts a use permitted by the draft or final development plan. Check your plot's zone and any reservation, such as a park or a road, in both the 1999 plan and the draft.

Land conversion after the 2025 reform

The Maharashtra Land Revenue Code (Second Amendment) Act, 2025 (bill text as gazetted on 8 December 2025, PRS India) rewrote sections 42 and 47 of the Code. Punekar News reported on 12 February 2026 that a Government Resolution had put it into effect. In short:

No Collector's permission is needed to change agricultural land to non-agricultural use if the draft or final Development Plan, the Regional Plan or the development control regulations permit that use.
The planning authority's permission does the conversion. Inside Thane city that is TMC; the revenue records, including the 7/12, are then updated.
A one-time premium replaces conversion tax and the annual NA tax, collected before permission at 0.1 per cent of the land's current ready reckoner value up to 1,000 sq m, 0.25 per cent from 1,000 to 4,000 sq m, and 0.5 per cent above that. As an illustration only, a 250 sq m plot with a ready reckoner land value of ₹1.5 crore would pay about ₹15,000. Rates: IGR Maharashtra.
Class II land is not upgraded by a building permission; those restrictions and any nazarana still apply.

Our Pune guide covers the reform in more depth, including land converted earlier. Two cautions for Thane: the reform only helps where the zone permits housing, and in a Regional Plan area, where the Collector is the building Authority, we could not find official guidance on how the premium is collected, so ask the Collector's office before you budget.

Building permission inside TMC

Your architect or licensed engineer files the proposal on BPMS, the Urban Development Department's online system. The portal lists services from building permission and plinth intimation to part and full occupancy. Its Procedure for Building Permission, written for municipal councils, shows the flow: owner e-KYC, uploads, a scrutiny fee, a site visit, scrutiny against the regulations, then development charges and a digitally signed permission. In practice you cannot file it yourself: the system is built around a licensed professional who signs the drawings.

UDCPR sets the clock:

Decision: after objections are complied with and plans resubmitted, the Authority must grant or refuse within 60 days (Regulation 2.6.1).
Deemed permission: if the Authority does not respond within 60 days of a complete notice with fees, the plans are deemed sanctioned, but only if they fully comply (Regulation 2.6.2). Do not rely on it without your architect's advice.
Plinth: once the plinth is complete, you file an intimation in Appendix F, certified by your architect or engineer, before building further. Officers inspect about 10 per cent of these cases (Regulation 2.8.4).
Occupancy: after the completion certificate, the Authority must issue or refuse the occupancy certificate within 21 days, failing which the work is deemed approved for occupation if it matches the sanctioned plans (Regulation 2.10).

Without an OC, utility connections, resale and home loans all become harder.

Cluster redevelopment in Thane

If your plot holds an old building, check whether it falls inside an urban renewal cluster before planning a standalone redevelopment. UDCPR's Urban Renewal Scheme (Regulation 14.8) applies to municipal corporations, including Thane, for clusters of at least 10,000 sq m in non-congested areas or 4,000 sq m in congested areas, on a road at least 18 m wide. Clusters come from the development plan or an Urban Renewal Plan notified by the Commissioner, and a note for Thane treats structures in gaothans merged into the corporation in 1982 as protected and legal. Ask TMC's town planning department whether your property sits in one.

The sequence, in one place

Confirm the authority for the survey number.
Pull the 7/12 or property card on Mahabhumi and read the holder, other rights and occupancy class.
Check the zone and reservations in both the sanctioned development plan and the 2024 draft revised plan.
Appoint an architect who files on BPMS.
File for permission, paying the one-time NA premium with it if the land is agricultural.
Build to plinth and file the plinth intimation before going higher.
Submit the completion certificate and obtain the OC.

Frequently asked questions

Who approves building plans in Thane?

Inside the city, the Thane Municipal Corporation under UDCPR 2020, through a licensed professional filing on BPMS. Neighbouring cities have their own corporations, MMRDA approves in its notified areas, and the Collector in Regional Plan areas.

Do I still need NA permission to build in Thane?

Not a separate one, if the draft or final development plan or the Regional Plan permits your use. Since the 2025 amendment, the building permission effects the conversion, with a one-time premium.

Has Thane's revised development plan been sanctioned?

We could not find a sanction notification as of October 2026 for the draft published in October 2024, so check both plans for your survey number.

Can my old building be redeveloped on its own?

Often, but first check whether it sits inside an urban renewal cluster under UDCPR Regulation 14.8, in which case the cluster plan may govern.

Approvals go faster when the person handling them has filed with your authority before. Browse architects on MOA, see their published work and message them directly, with no commission on either side.
