20x30 House Construction Cost in Davanagere 2026: The Rental Yield Math

Davanagere has a large student and working-tenant population around the engineering and medical colleges, and the 20×30 is the plot size that most often gets built specifically to serve it.

So rather than just the build cost, here is the actual return math.

What Fits on 600 sqft

A 20×30 is 600 sqft of land. After DCC setbacks — roughly 1.0m front and rear, 0.6m sides for this plot size — you get about 450–500 sqft of built-up area per floor.

The G+2 is where the numbers get interesting.

Build Cost

Brick construction adds ₹100/sqft — ₹1.0 L on a G+1, ₹1.5 L on a G+2.

The Rental Math

A self-contained 450–500 sqft floor near the college belt in Davanagere typically lets for ₹9,000–13,000/month furnished-basic, depending on locality and whether it is let as a single unit or shared.

On a G+2 where you live on the ground floor and let two floors:

That is gross, on construction cost only, excluding land. Net of maintenance, vacancy and property tax, expect roughly two-thirds of it.

Two things that change the answer materially:

• Separate entrances. A rental floor with its own external staircase commands meaningfully more and lets faster than one you reach through the owner's hallway. Design it in from the start — retrofitting an external stair on a 20-foot-wide plot is close to impossible.
• Separate meters. Individual HESCOM meters per floor remove the single biggest source of tenant friction. Ask for this at the sanction stage.

The Davanagere Variable: Black Cotton Soil

This matters more on a small plot, not less.

Soil treatment cost is driven by footprint and depth, not by how many floors sit above. So the ₹1–2 lakhs it may add lands on a ₹20–30 lakh build rather than a ₹50 lakh one — a proportionally bigger hit.

And a specific warning for rental builds: a G+2 concentrates far more load onto a small footprint. If you are building three floors on 600 sqft over black cotton soil, the soil test is not optional. Get it before the design, not after.

Designing for Letability

• Staircase against the side wall, external if the rental floors are let separately.
• Each floor self-contained — own kitchen, own bathroom. A shared kitchen halves your rent.
• Cross-ventilation matters here. Davanagere summers are hot and tenants leave units that do not breathe. Windows on two walls per unit, minimum.
• Taller floor height helps. The 10'6" in Signature over the 10'0" in Foundation is a genuine comfort difference in this climate, and it shows in what you can charge.

Costs Outside the Rate

Budget an extra ₹3.5–6 lakhs all-in for a G+2, more if the soil report calls for a raft. Note the per-meter electricity cost if you are metering floors separately.

Build Time

8–11 months for a G+1, 11–14 months for a G+2. Add 2–4 weeks if a raft foundation is required.
