The deal analysis tool built for small developers, architects, and community-scale investors evaluating missing middle housing. Know before you commit.
Analyze a Deal →Single-family exclusionary zoning is being eliminated across the country. But knowing you can build a fourplex doesn't mean you should.
Existing deal analysis tools are built for institutional investors or house flippers. Nothing addresses the zoning, parking, and setback math that kills small infill deals.
Of rezoned parcels remain undeveloped. The opportunity is there. The confidence isn't. Small developers need clarity, not complexity.
Input your parcel's zoning code. InfillCalc calculates max units, setbacks, parking requirements, and FAR limits so you know what's buildable before you model the finances.
Per-unit cost estimates calibrated for missing middle typologies. Duplexes cost differently than fourplexes. Renovations cost differently than ground-up. We know the difference.
NOI, cap rate, cash-on-cash return, and development margin in one clear output. A definitive answer to "does this deal pencil out?" before you spend a dollar.
Triplex vs. fourplex? Renovate vs. build new? Compare scenarios side by side and find the configuration that maximizes returns on your specific site.
You've built a few projects. You see an empty lot. You need to know if a triplex makes sense before you go to the bank.
Clients ask if a project is financially viable. Now you can answer with numbers, not guesses. Add feasibility analysis to your services.
You want to build housing in your neighborhood. InfillCalc gives you the confidence to commit capital where it matters most.
InfillCalc exists so the numbers never stand in the way of the right project.
