Can You Build a House in Patna's Green Belt? Master Plan 2031 Rules
Quick answer
Patna's "green belt" is the green zones on the Master Plan 2031 map. A house there is allowed only under strict conditions.
- Urban Agriculture zone: non-leasehold land, house on at most 20% of the plot, up to 7 m tall, 60%+ under plants or farming.
- Conservation zone: plotted housing is prohibited. Only dwellings for people who farm the land.
- The 100 m belt around village settlements is different: ordinary houses are allowed.

Can you build a house? Green zone by zone
Cheap plots towards Bihta, Naubatpur, Phulwari, Sampatchak, Punpun or Fatuha are often green belt land. Sellers rarely say so. Buyers find out when the building plan is refused.
| Zone | Can you build a house? | FAR | Where |
|---|---|---|---|
| Urban Agriculture | Yes, with conditions: 20% coverage, 7 m height, 60% of land under plantation/farming, not leasehold | 0.75 | The band around the core city and around the proposed townships at Bihta, Naubatpur and Fatuha |
| Conservation | Plotted housing prohibited. Farm dwellings allowed. Other residential use only with the Authority's special approval, at 2% ground coverage | 0.50 | Beyond the urban agriculture band: most of the remaining rural area |
| Bio-Conservation | Not meant for housing; earmarked for riverfront and public recreation | — | Ganga lagoons and the land along the Punpun |
| Open Space Buffer | No; no construction within at least 9 m of a minor watercourse and 15 m of a major canal | — | Along rivers, canals and water bodies |
| Village settlement + 100 m belt (not green, but inside this area) | Yes, all types of residential buildings | 1 | The village settlement and 100 m outside it |
FAR (floor area ratio) is the total floor area on all floors compared with the plot. At FAR 0.75, a 1-kattha plot (about 1,361 sq ft) could carry about 1,021 sq ft. In the green belt, though, the coverage and height rules bind first.

Urban Agriculture zone: the four conditions for a house
A house may be permitted only if all four are met:
- The land is not leasehold.
- Ground coverage is not more than 20%.
- Building height is not more than 7 m.
- At least 60% of the land is used for plantation or agriculture.
Also permitted: farming, horticulture, dairy and poultry, farm houses, parks, and storage and sale of farm produce. Schools, agro-processing, cold storage, godowns and expansion within existing homestead land need the Authority's special approval. Heavy industry, slaughter houses, wholesale mandis and hazardous storage are prohibited.
Townships: the Authority can allow planned township projects here, with the approval of the Bihar Urban Planning and Development Board. A builder selling a green-belt "township" must show that approval. Cutting farmland into plots is not a planned township.
How big a house on a 2- or 5-kattha green belt plot?
Figures use the Patna kattha of about 1,361 sq ft (check your deed). A 7 m height limit usually means ground + one floor.
| Plot | Area | Ground floor (20%) | Ground + 1 floor | Plantation/farming (min 60%) |
|---|---|---|---|---|
| 1 kattha | ~1,361 sq ft | ~272 sq ft | ~544 sq ft | ~817 sq ft |
| 2 kattha | ~2,723 sq ft | ~544 sq ft | ~1,089 sq ft | ~1,634 sq ft |
| 5 kattha (~15.6 decimal) | ~6,806 sq ft | ~1,361 sq ft | ~2,722 sq ft | ~4,084 sq ft |
| 10 kattha | ~13,613 sq ft | ~2,722 sq ft | ~5,445 sq ft | ~8,168 sq ft |
What this means: a 1–2 kattha plot here won't take a normal family home. On 1 kattha the ground floor is about 272 sq ft, roughly one large room. The zone is meant for low-density, farmhouse-style homes on large plots. "Three floors, no problem" on a 1–2 kattha "green belt colony" plot does not match the rules.
Conservation zone: can you build at all?
The Conservation zone is the largest rural part of the planning area. Its rules are stricter:
- Permitted: farming, horticulture, forestry; dwellings for people engaged in farming; existing homes and village settlements; cottage industries without power; storage of farm produce; fuel stations; resorts and riverfront uses.
- Only with the Authority's special approval: apartment-type housing, higher institutes, hospitals, and other residential use at 2% ground coverage.
- Prohibited: plotted housing, small industries or institutions, and any development between a river/canal/stream and its embankment.
How tight is 2%? On 1 acre (about 32 kattha), about 871 sq ft of ground coverage. On 2 kattha, about 54 sq ft. A small plot cut out of a Conservation field has almost no legal route to a house.
The 100-metre village belt rule
This is the most useful rule for green-belt landholders. Village settlements recorded in the revenue maps (khasra maps) are in the Village Settlements zone. It lies outside the core and growth nodes. A 100 m belt outside the settlement also counts as that zone, for natural growth. FAR here is 1.
The report is explicit: even if this belt looks like Conservation on the map, it is not Conservation. All types of homes, clinics, schools, shops, places of worship and household industries are permitted.
In practice: check your plot's distance from the settlement boundary on Bhu-Naksha. For a large deal, get the plan-approving office to confirm in writing where the boundary is measured from.
How do I check whether my land is in the green belt?
- Is the village in the Patna Planning Area? Take the block and mauza from your khatiyan or jamabandi. The 13 blocks and 575 villages are in our master plan guide.
- Look at Map 21 in the report (free on the PMAA website): is your area orange (residential) or green?
- Match it with the khesra map from Bhu-Naksha; the distance to the village shows there too.
- Get it in writing from the plan-approving office (municipal body or PMAA). Do this for any plot near a boundary or any large deal. A seller's word is not enough.
- Builder colony? Ask for the layout approval, the Board's township approval if in the Urban Agriculture zone, and the RERA registration.
What should you do before buying a green belt plot? (Our advice)
- Zone first, price second. Green belt land is cheaper because little can be built on it. Don't pay residential prices for it.
- "We'll get the plan passed"? Ask for it in writing, with the rule it relies on. No agent can change the conditions above.
- Avoid small plots. 1–2 kattha in Urban Agriculture won't take a usable house; plotted housing is prohibited in Conservation.
- Measure the distance to the village. Within 100 m, the far easier Village Settlements rules may apply.
- Check rivers and canals: nothing between a river or canal and its embankment, plus the 9 m and 15 m buffers.
- Papers still matter: Patna plot buying guide and how to avoid land fraud.
Patna green belt: frequently asked questions
Can green belt land be registered?
Yes. A zone doesn't stop a sale; its rules apply to construction. So a registered deed is no proof a house can be built. Exception: in the Patliputra Township special area (273 villages, 9 blocks), sale reopened on 1 August 2026 but construction is banned until 30.03.2027. A draft Development Plan 2047 is to replace PMP 2031 there. See registry open, construction banned and the village list.
Land conversion has ended. Is building in the green belt easier now?
No. The revenue conversion law was repealed in 2026, but in the Patna Planning Area the master plan zone still decides. The plan says no change of land use until zonal plans are made. Relaxation for government-sponsored projects doesn't cover private plots. Details: land conversion repealed.
A house already stands on green belt land. Is it legal?
A use that was lawful before the rules came in may continue. But a non-conforming use can't be extended or enlarged. A house built later without an approved plan doesn't become legal because of this.
Can the zone be changed, so I buy now and wait?
No change of land use is permitted until zonal plans are made, and most zones have none notified yet. There is no fixed route or date, so don't buy on the hope of a zone change.

Is "green belt" an actual master plan zone?
There is no zone called "Green Belt" in the Patna Master Plan 2031. The building rules list the zones: residential, commercial, industrial, public/semi-public, open space, old city, urban centres, village settlements, urban agriculture, conservation, water bodies, special reservations and transport. "Green belts" appear only as a permitted use inside the Open Space zone.
People say "green belt" because these zones are shaded green on the map. The report groups them as "Green cover (Forest, Bio Conservation, Urban Agriculture)", about 525.97 sq km, of which Urban Agriculture is about 134.06 sq km. The planning area is 1,167.04 sq km, and roughly half (49.89%) is not meant for urban development.
