Methodology

Every output is explainable.

UnlockLand is decision intelligence, not a black box. Behind every buildable-area estimate, yield study, feasibility score, and return figure sits a traceable chain of planning rules, stated assumptions, and cited data sources. This page explains exactly how that chain works.

From parcel to decision

Real parcels. Real planning rules. A result you can defend.

The reasoning pipeline — five recorded stages from raw parcel data to a cited, defensible result.

Principles we hold every result to

These are the commitments that make an UnlockLand output something you can defend in front of a lender, a planning officer, or an investment committee.

Traceable
Every number has a why

Open any result to see the rule, the assumption, and the data point it came from. Nothing is asserted without provenance.

Transparent
Assumptions are stated

We never bury inputs. Cost, revenue, timing, and risk assumptions are labeled and shown alongside the output.

Editable
Your inputs override ours

Defaults get you started fast, but you can replace any assumption with your own numbers and instantly recompute.

Honest
Uncertainty is flagged

Where data is incomplete or a bylaw is ambiguous, we say so and show ranges instead of false precision.

How an address becomes a decision

Each step is recorded, so you can open any result and trace it back to the rule and data point that produced it.

1
Identify the parcel

We resolve the address to a legal parcel and pull its geometry, lot dimensions, and jurisdiction.

Inputs: parcel boundaries, lot area, frontage, jurisdiction
2
Apply planning rules

Zoning designation, overlays, density, setbacks, height, and parking rules are layered onto the parcel to determine the legal envelope.

Inputs: zoning code, overlays, bylaw constraints
3
Generate buildable options

Within the legal and physical envelope, the AI produces massing and unit-mix scenarios that respect every binding constraint.

Inputs: envelope, efficiency ratios, product types
4
Test feasibility

Each scenario is run against construction cost, revenue, timing, and risk assumptions to produce a feasibility view.

Inputs: cost rates, sale/rent values, absorption, contingency
5
Compute and compare returns

We model the pro-forma, derive returns, and rank scenarios so you can choose the highest-and-best use with the trade-offs visible.

Inputs: capital stack, financing terms, exit assumptions

Planning rules we apply

UnlockLand encodes the constraints that govern what can legally and physically be built on a parcel. When a rule changes by jurisdiction or is ambiguous, we surface it rather than hide it.

Zoning & land use

Permitted uses, density caps, and the designation governing what can be built.

Setbacks & yards

Front, rear, and side setbacks that shape the buildable footprint.

Height & storeys

Maximum height, storey limits, and angular planes where applicable.

FAR / FSR & coverage

Floor-area ratios and lot coverage that cap total buildable area.

Parking & access

Minimum or maximum parking ratios and access requirements.

Overlays & constraints

Heritage, flood, environmental, and other overlays that modify base zoning.

Assumptions, made visible and editable

Feasibility and returns depend on assumptions. We default to market-calibrated values, label every one, and let you override them — because your numbers should be yours.

Construction cost

Hard and soft costs per buildable area, calibrated to product type, market, and recent escalation.

Default source: Market cost indices + regional benchmarks
Revenue

Sale prices or rents per unit and per area, drawn from comparable projects in the submarket.

Default source: Comparable sales & lease data
Timing & absorption

Entitlement, construction, and lease-up or sales durations that drive cash-flow phasing.

Default source: Regional delivery benchmarks
Risk & contingency

Planning, market, and execution risk expressed as contingencies and scenario adjustments.

Default source: UnlockLand risk model

Where our data comes from

We combine authoritative public records with continuously refreshed market data. Each output carries the provenance of the data it relied on.

Government

Municipal and regional zoning codes, official plans, bylaws, and parcel registries — the authoritative basis for what is permitted.

Geospatial

Parcel boundaries, topography, overlays, and mapping layers used to model the physical and legal envelope.

Market

Comparable sales, lease rates, and absorption data refreshed continuously to keep revenue assumptions current.

Cost

Construction cost indices and regional benchmarks for hard and soft costs by product type.

User & partner

Project inputs and professional workflows contributed by owners, builders, and consultants, used to refine context.

How feasibility and returns are computed

Buildable area

Derived from the binding constraint among FAR/FSR, coverage, setbacks, and height — we apply whichever rule produces the smallest legal envelope, then net for efficiency.

Yield & unit mix

Buildable area is allocated across product types using efficiency ratios and minimum unit sizes to estimate achievable units.

Feasibility score

A normalized read combining capacity, planning risk, cost intensity, and return potential — designed to compare scenarios, not replace underwriting.

Returns

A pro-forma projects revenue, costs, and financing across the timeline to produce margin, yield-on-cost, and IRR under your stated assumptions.

UnlockLand outputs are decision-support estimates, not appraisals, investment advice, or guarantees of permit approval. Always validate critical assumptions with qualified local professionals before committing capital. See our Terms of Service.
