NBC Setback & R-1 Zoning Calculator

Calculate open space requirements for a Basic Residential 1 (R-1) lot based on the National Building Code (PD 1096).

Calculation Result

For an R-1 lot of 200 sq.m, the Maximum Allowable Percentage of Site Occupancy (PSO) is 50%, and the Minimum Total Open Space within Lot (TOSL) is 50%.
Max Footprint=200×0.50=100 m2Required Open Space=200×0.50=100 m2\begin{aligned} \text{Max Footprint} &= 200 \times 0.50 = 100 \text{ m}^2 \\\\ \text{Required Open Space} &= 200 \times 0.50 = 100 \text{ m}^2 \end{aligned}
