Project profit on a development site across a range of home sizes. Enter sale price and build cost per square foot, and choose a fee schedule: Rohnert Park fee areas are built in, or enter your own.
Price and build cost per sf
Dollars per living sf. Values for sizes in between are straight-line between these two points.
Site and soft costs
Density
Homes per acre is straight-line between the two sizes, times acres, rounded down to whole homes.
Fees and other costs
Total project profit by home size
Per-home fees. The Rohnert Park schedules use the City’s Development Impact Fees handout (rev. July 16, 2026) for single-family homes, plus the Cotati-Rohnert Park Unified School District fee of $5.38/sf (effective August 10, 2026). The fee area matters: pick the one the site is in. Not included: building permit and plan check fees, parkland dedication or in-lieu fees set at map approval, the Copeland Creek drainage fee ($630 per acre, if in that district), per-acre Wilfred Dowdell fees, financing, and subdivision and planning fees. Choose Custom to enter fees for any other jurisdiction.
Sale prices, costs, density and fees are your assumptions, not market data.
