Direct Answer

ADU potential can help a sale story when the opportunity is realistic, documented, and properly caveated. Buyers will still underwrite zoning, access, parking, construction cost, time, rent control, and execution risk.

Why It Matters

ADU Potential and Apartment Building Value matters because buyers do not price Westside apartment buildings from headlines alone. They review income, expenses, jurisdiction, condition, debt, documentation, and the risks that could appear during diligence.

Owner Takeaway

Use the concept as a screening lens, not a final answer. The building-specific conclusion should come from the rent roll, actual expenses, property condition, local rules, recent sales, and current buyer demand.
