There is no new KMBR 2026 rulebook. Here is what the October 2025 and August 2026 amendments to Kerala's Municipality Building Rules change for a house: permits, yards, road setbacks, roofs and fees.
Before you rely on any of this: this guide reads the Kerala Gazette text of the 2019, 2021 and October 2025 rules. The August 2026 amendment is described from a published legal update, because its gazette text was not on the Local Self Government Department's site when we checked on 2 November 2026. Rules change, and fee figures below are our reading of the schedules. An architect or your local body's help desk confirms what applies to a specific plot. This is a plain-English guide, not legal advice.
There is no new rulebook called KMBR 2026. Kerala's municipal corporations and municipalities still follow the Kerala Municipality Building Rules, 2019 (KMBR), but most of what matters for a house was rewritten on 29 October 2025, and a short amendment followed in August 2026. If you are building in 2026, you are building under KMBR 2019 as amended by both.
For a typical home, the changes are good news: no height cap for self-certified permits, more flexible yards, smaller road setbacks on narrow lanes, and an occupancy certificate once the essentials are done. This guide goes through each change, then the fees and the steps in order.
KMBR 2019 was issued as G.O.(P) No. 77/2019/LSGD and published in the Kerala Gazette on 8 November 2019, replacing the 1999 rules. Since then:
KMBR applies in corporations and municipalities. Grama panchayats follow the Kerala Panchayat Building Rules, 2019 (KPBR), which were amended in step. For which body issues your permit, and the land and coastal checks that come before it, see our guides for Kochi and Thiruvananthapuram.
The 2026 amendment is short. TeamLease's summary describes two new provisos in rule 26, the yards rule, and one in rule 33, the room height rule:
All three sentences were in the original 2019 rules. The October 2025 amendment replaced rule 26 and rule 33 wholesale: the new text dropped the front yard and air-conditioning lines and reworded the 50 cm relaxation. So the 2026 amendment is best read as restoring the 2019 wording. Rule 33 does not apply to residential buildings, so the air-conditioning line matters for shops and offices, not your house. The front yard line does: in 2019 it relaxed a 3 m front yard to 2 m for houses on narrow unnotified roads. Ask your architect to confirm how the gazette wording sits alongside the 2025 average yard before you fix the front of the plan.
Low risk buildings get an Acknowledgement Certificate, which the rules treat as the permit, on the owner's and licensee's self-certification. The 2025 rules widened the definition for houses:
| Residential (Group A1) | 2021 rules | 2025 rules |
|---|---|---|
| Built-up area | Under 300 sq m | Under 300 sq m |
| Height | Under 7 m | No limit set |
| Storeys | Two | Two, excluding basement |
So a two-storey house under about 3,229 sq ft with a pitched roof or a tall ground floor no longer drops out of the fast route because it crosses 7 m. The 2021 rules give the Secretary five working days to issue the certificate. Kerala Kaumudi reported the department's estimate that about 80 per cent of houses can now get permission within minutes.
Rule 26 and Table 4 were replaced. Each yard now has a minimum and an average, and the average is worked out from the area of the yard. That suits irregular plots and stepped plans: one part of the building can come closer to the boundary if the rest of that face stands further back.
| Yard (buildings up to 10 m) | 2019 rules | 2025 rules: average / minimum |
|---|---|---|
| Front, ordinary house | 3 m | 3 m / 1.8 m |
| Rear, ordinary house | 1.5 m | 1.5 m / 1 m |
| Sides, ordinary house | 1 m | 1 m / 1 m |
| Front, small plot | 2 m | 1.8 m / 1.2 m |
| Rear, small plot | 1 m | 1 m / 0.5 m |
| Sides, small plot | 0.6 m | 0.6 m / 0.6 m |
A "small plot" is up to 125 sq m (about 1,345 sq ft, or roughly 3 cents) with a building up to 200 sq m. Two other provisos matter for tight sites:
For how yards, coverage and height interact in general, see our explainer on setbacks, FAR and height limits.
Rule 23 sets a separate minimum distance from a road, and the stricter of it and Table 4 applies. It is still 3 m from highways, district roads, notified roads and any unnotified road 6 m or wider, and 2 m from unnotified roads under 6 m. The 2025 changes are on small roads:
Rule 24's limit on height by street width no longer applies to single or two-unit houses up to 8 m high.
Rule 74 now lets single and two-unit houses up to three storeys and 10 m add a sheet or tiled sloping roof over the terrace, open on all sides, with up to 2.4 m clear between terrace and roof (it was 1.8 m). It is not counted in built-up area. The 2019 wording said the Secretary "may permit" it and charged a permit fee; the 2025 wording drops both. A new rule 74A allows a sheet roof of up to 15 sq m in the front and rear yards of houses up to 300 sq m, open on three sides and at least 60 cm from the road boundary, with rainwater kept on your plot.
Schedule I and Schedule II were replaced in October 2025. For a house (Group A1), per sq m of built-up area:
| Built-up area | Corporation | Municipality |
|---|---|---|
| Up to 80 sq m | ₹5 | ₹3.50 |
| 80 to 150 sq m | ₹20 | ₹17.50 |
| 150 to 300 sq m | ₹70 | ₹60 |
| Above 300 sq m | ₹150 | ₹150 |
The application fee is ₹150 up to 100 sq m, ₹500 from 100 to 300 sq m, and ₹4,000 (₹3,000 in a municipality) above that. The schedule sets the slab by the building's total built-up area. Worked example: a 140 sq m (about 1,507 sq ft) house in a corporation pays 140 × ₹20 = ₹2,800 permit fee plus ₹500 application fee, ₹3,300 in all. At 160 sq m it moves to the ₹70 slab: 160 × ₹70 = ₹11,200 plus ₹500. If your design is just over 150 sq m, it is worth asking your architect whether it needs to be. K-SMART calculates the final figure. For the cost of the build itself, see our Kochi construction cost breakdown.
From the rules: five working days for the Acknowledgement Certificate on a self-certified application, and fifteen days for the Secretary to decide a regular permit (both from 2021). LSGD's building permits page adds that you may appeal if 15 days pass, and that a permit not decided within 30 days is deemed granted. Under the 2025 rules, if the documents and drawings are verified online, the physical site check is no longer required before the permit and happens at plinth stage instead.
Occupancy. A single or two-unit house up to 500 sq m can now get its occupancy certificate once the structure, external doors, minimum sanitation and stair handrails are complete, so finishing work need not hold it up. If a yard comes out short, the Secretary may allow a tolerance of 5 per cent of that yard or 25 cm, whichever is less.
Built without a permit? A permit can be granted for work already started at twice the permit fee for the part built. It is a remedy, not a plan.
Bigger homes. New buildings over 300 sq m need rainwater storage, and new homes over 300 sq m a biodegradable waste system unless an organised collection system exists. Houses over 500 sq m need a solar installation sized by Table 19.
Under Chapter XXI of KMBR 2019, plans must be prepared and signed by a person registered under the rules. An architect registered with the Council of Architecture under the Architects Act, 1972 is deemed registered and may sign all plans for a building permit; chartered engineers registered with the Institution of Engineers (India) are deemed registered too. Your guide to what the set should contain is our drawing set explainer.
There is no single KMBR 2026 book. Read the 2019 rules together with the October 2025 amendment gazette on LSGD's site, linked above, and watch LSGD's gazette list for the August 2026 text. If you buy a printed copy, check that it includes the 29 October 2025 amendment.
For a house under 300 sq m and two storeys, a self-certified permit on K-SMART. Yards for an ordinary plot average 3 m in front, 1.5 m at the rear and 1 m at the sides, with the road setback from rule 23 on top. FSI is 3 without extra fee and coverage 65 per cent.
Under rule 74 as amended, a single or two-unit house up to three storeys and 10 m can add an open sheet or tiled roof up to 2.4 m above the terrace, and it does not count as built-up area. The department told Kerala Kaumudi no permission is needed; confirm with your local body.
No. Panchayats follow KPBR 2019, which was amended alongside KMBR in October 2025 and again in August 2026. Check the KPBR text for panchayat plots.
