The Buildability Score™ Methodology
Data version: Q2 2026 · Last updated 2026-04-26
TL;DR. The Buildability Score™ is a 0-100 composite property-feasibility indicator developed by Buildability™. It analyzes 142 factors across 6 dimensions to answer one question: "Can I actually build something here, and how hard will it be?" The output is a score (0-100), a letter grade (A+ through F), and a plain-English verdict. It is the fastest way to triage any U.S. property for development potential.
The three-layer formula
Buildability Score = Gate Status × (Σ wᵢ × xᵢ) × Confidence Modifier. Layer 1 is Gate Status — a binary check for dealbreaker conditions (prohibited use, no utility access, severe environmental blocker). If any gate triggers, the score is zero regardless of other factors. Layer 2 is the weighted sum of 142 normalized factor values across 6 dimensions. Layer 3 is the confidence modifier — a multiplier that down-weights the final score based on data completeness, so a score built from 18/20 verified sources rates higher than one with 12/20.
The 6 dimensions
Zoning Compliance (30% weight, 24 factors): use permissions, setbacks, FAR, height, coverage, overlays, ADU eligibility, parking, density. Environmental Risk (25% weight, 28 factors): FEMA flood zone, wildfire hazard, seismic risk, soil, wetlands, air quality, EPA sites, radon, contamination proximity. Infrastructure Readiness (15% weight, 18 factors): water, sewer, electric, gas, broadband, service confirmation, hookup capacity, distance to main lines. Market Feasibility (15% weight, 22 factors): comparable sales, price per sqft, days on market, trends, absorption, vacancy, rental yield, opportunity zones. Approval Friction (10% weight, 20 factors): review transparency, expedite availability, timeline, consistency, public process, variance history. Data Confidence (5% weight, 30 factors): source coverage, freshness, cross-validation, ambiguity flags.
Regional weighting adjustments
The weighting matrix shifts by region to reflect dominant risk factors. Florida: environmental risk weighted 40% to reflect flood and hurricane exposure. California: regulatory compliance weighted 45% to reflect complex entitlement processes and CEQA. Texas: infrastructure weighted 25% because utility access varies widely across undeveloped parcels. Coastal jurisdictions: environmental weighted higher. Rural jurisdictions: infrastructure and market factors weighted higher.
Score interpretation
A score of 85+ (A/A+) signals a strong development candidate with few obstacles. 70-84 (B/B+) indicates a buildable lot with manageable constraints. 55-69 (C) suggests a project is possible but requires specialized work or entitlement effort. 40-54 (D) warns of serious constraints that will likely require variances, waivers, or site modifications. Below 40 (F) is a hard stop — usually because a gate has triggered. A gate-triggered score of zero means at least one dealbreaker condition exists (no access, prohibited use, severe environmental blocker) that cannot be worked around without a code change.
Why it is better than a human zoning consultant
A human consultant spends 2-8 weeks manually checking zoning code, calling the planning department, pulling FEMA maps, and writing a narrative report. They charge $2,000-$4,500 per property and typically cover 40-80 factors. Buildability™ covers 142 factors, pulls from 20+ live government APIs, runs multi-model AI analysis (Claude, GPT-4o, Gemini) for consensus, and returns results in about 20 seconds. For about 1% of the cost and 0.01% of the time, Buildability™ delivers more comprehensive due diligence than most consultants produce.
