30x40 Sites in Mysore: What the Dimension Means and What You Can Build
The short answer
A 30x40 site is 1,200 square feet of land and the default unit of the Mysore market. What that gives you once setbacks and floor-area limits are applied, and what to check before buying one.
What 30x40 means
A 30x40 site is 30 feet wide by 40 feet deep — 1,200 square feet of land, and the standard unit of the Mysore market. It measures land, not the house you can build on it.
The dimension is land, not floor space
Search results confuse this constantly, because the big national portals match "30x40" against their price filter and return sites priced between thirty and forty lakh. The dimension has nothing to do with price. It is thirty feet of frontage by forty feet of depth: 1,200 square feet of land, before a single wall is built.
The related sizes in the same market are 20x30 (600 sq ft), 30x50 (1,500), 40x40 (1,600), 40x60 (2,400) and 50x80 (4,000). When someone in Mysore says "a site" without qualifying it, the 30x40 is usually what they mean.
How much of a 30x40 you can actually build on
Not all of it. Setbacks — the open space that has to be left at the front, rear and sides — take a share of every plot, and the share is proportionally larger on a small one. Parking has to fit somewhere. Karnataka building rules also cap the total floor area through a floor-area ratio tied to plot size and the width of the road in front.
The practical consequence for a 30x40 is that ground coverage lands well short of the full 1,200 sq ft, and the floor-area cap starts to bind once you go past two floors. A G+1 on a 30x40 does not enclose twice 1,200 square feet, and a G+3 does not enclose four times it. Ask an architect for the numbers on the specific site and the specific road width before you plan around a figure.
Facing, road width and corners
East and north facing sites carry a premium in this market. Road width in front of the site affects the floor-area ratio you are permitted as well as access. A corner site gains light and access on two sides and loses buildable area to the second setback — which is also why corner sites are auctioned separately by the development authority.
What to check before buying a 30x40
Measure it. A site sold as 30x40 that measures 29x39 is smaller than the deed says and the difference is yours to discover. Beyond the tape: the approval status of the layout, the khata, the encumbrance certificate, whether the road is formed and asphalted, and whether the layout has actual construction in it or has stood empty for years.
A note on prices
The price of a 30x40 in Mysore varies by locality more than by anything else, and by approval status within a locality. We do not publish a rate table here, because a rate we cannot source honestly is worth less than none. What is listed on this site is real and current, and the listing pages show it.
Check it at source
Dimensions, approval and guidance value are all matters of record:
Mysore Urban Development Authority (MUDA)
The authority that sanctions layouts, allots sites and publishes e-auction notifications in Mysuru.
Kaveri Online Services, Department of Stamps and Registration, Government of Karnataka
The state registration portal — property registration appointments, encumbrance certificates, certified copies and the guidance-value lookup.
Fees, dates and document lists are set by these authorities and change. Where this guide describes a procedure, the notification or the department's own page is the authority — not this page.

Frequently asked questions
How many square feet is a 30x40 site?
1,200 square feet of land — 30 feet of frontage by 40 feet of depth.
How big a house can I build on a 30x40 site?
Less than the site area per floor, because setbacks and parking take a share, and the floor-area ratio caps the total across floors. Get the figures for the specific site and road width from an architect.
Does 30x40 mean the price is 30 to 40 lakh?
No. That is a search artefact from national portals matching the dimension against a price filter. 30x40 is a measurement of land.
Is a 30x40 site a good size in Mysore?
It is the default unit of this market, which makes it the easiest size to buy and the easiest to sell on. Whether it suits you depends on the house you want to build.
