Construction is usually the largest single line in a housing budget. It divides into hard costs (the physical building: labor, materials, site work, the general contractor’s fee) and soft costs (architecture, engineering, permits, legal, insurance, financing fees and the developer’s own overhead). A contingency sits on top of both because estimates are never exact.
Construction cost enters rent through capital. Every dollar spent on the building must be borrowed or invested, and both lenders and investors expect to be paid. Under the assumptions in our shared model, each $10,000 of cost per unit requires roughly $68 per month in additional rent, so a change in the price of lumber, labor or a building-code requirement is also a change in the rent a new building must charge.
Articles in this section explain where construction dollars go, why costs differ by building type, what drives them up or down, and what any given requirement adds to the cost of a unit.
