Additional Residential Unit

Additional Residential Unit: a practical Canadian real estate investor guide to underwriting use, deal risk, common traps, and Realist.ca implementation.

Definition

Additional Residential Unit is a real estate term investors use to assess as-of-right value, entitlement risk, construction timing, municipal charges, and whether density is theoretical or buildable.

Example

An investor reviewing a Canadian property tags additional residential unit as a diligence item, links it to source documents, and reruns the model if the answer changes purchase price, closing certainty, rent, financing, capex, or exit value.

Why It Matters

Additional Residential Unit matters because it changes as-of-right value, entitlement risk, construction timing, municipal charges, and whether density is theoretical or buildable. The mistake is treating it as paperwork when it is really a deal constraint.

Investor Interpretation

Use additional residential unit as a decision filter: if it cannot be verified, priced, insured, financed, or managed, the right move is a lower offer, stronger condition, larger reserve, or a walk-away.

Realist Tie-In

Realist.ca can make Additional Residential Unit searchable, connect it to related guides, attach it to saved deal analyses, and surface the right checklist/calculator beside listings, underwriting pages, and investor lead magnets.
