Highest & Best Use\n\nThe legally permissible, physically possible, financially feasible, and maximally productive use of a site. How to reason about it.

Going Deeper (Intermediate)

Highest and best use (HBU) is the use that is legally permissible, physically possible, financially feasible, and maximally productive. It answers "what should go here?" and drives everything downstream.

Advanced / Pro-Level

Apply the four tests rigorously:

1. Legally permissible — zoning/entitlements (may require a rezone — a speculative play).
2. Physically possible — size, shape, topo, soils, access, utilities.
3. Financially feasible — market demand + returns that pencil.
4. Maximally productive — of the feasible options, the one with the highest residual land value. Use a market study to confirm demand and the residual land value method (what the land is worth given the best use's profit) to compare uses and decide what to pay. HBU "as vacant" vs "as improved" can differ. Challenge.

Practice Challenge

A site is zoned for retail, but the market is saturated with retail while apartments are in high demand and would yield far more profit. What does HBU analysis suggest? (Answer: apartments may be the highest and best use if a rezone is feasible — it passes physical/financial/maximally-productive tests; the play is to entitle (rezone) to the use the market actually rewards, since legally-permissible can be changed.)

In Practice

A corner lot zoned commercial would earn far more as retail than the single house someone wants to build. Highest-and-best-use analysis reveals what the land should become.

Common Mistakes to Avoid

• Underusing a valuable site
• Ignoring what's legally permissible
• Skipping the financial feasibility test

Takeaway: Ask what use is legal, possible, feasible, and most productive — that's the highest and best use.
