The 2026 ranking
Resale ROI varies sharply by project type. From highest recoup to lowest:
- Deck and outdoor additions: 65–75%. The return champion. They extend living square footage for a fraction of an interior project’s cost.
- Kitchens and finished basements: up to 70%. The highest-impact interior work, adding usable space and buyer appeal.
- Bathroom additions: 53–60%. Solid recoup, faster sales, real daily value.
- Master suite additions: 50–60%. Strong when the home lacks a primary suite buyers expect.
- Second-story additions: 40–50%. Lower recoup because of the structural tie-in cost, but the right move when moving is off the table.
The outlier: ADUs
ADUs do not fit the resale-recoup chart cleanly because their biggest return is rent, not resale. They add roughly 41% of cost in appraisal value, then pay monthly on top. Over five to seven years, many fully recoup on rental income alone. See our ADU cost and ROI guide.
How to use this
ROI is one input among several. The best project is the one that fits how you live and how long you will stay. If you are renovating to sell soon, weight the recoup numbers. If you are staying, weight daily use and let the return be a bonus. Get a tailored range from our cost estimator.
