How does Hawaii compare with the national average for a wood deck addition?

Homeowners in Hawaii typically recoup about 97% of the project's cost at resale, versus ~83% nationally. Hawaii is part of the Pacific Census division, which has the highest renovation resale returns of the 9 U.S. divisions.

What most affects the actual return in Hawaii?

Recency and condition. In Roots' model, work under 2 years old counts fully toward resale value, then depreciates toward ~20% after 10 years. A home with a documented maintenance record also typically sells closer to asking. Market conditions in the Pacific division set the regional baseline.

Where do these numbers come from?

Roots calibrates the national baseline for a wood deck addition against the 2024 Cost vs. Value Report (Zonda), then applies a Pacific-division adjustment derived from division-level averages in the 2024 Cost vs. Value Report, plus the model's own age and condition factors. Figures are modeled estimates, not appraisals.

Is a wood deck addition worth it in Hawaii?

Quick answer: It can be. In Hawaii, a wood deck addition typically returns about 97% of its cost at resale, above the ~83% national average. You likely won't recoup the full cost, but Hawaii is one of the stronger markets for it.

How Hawaii compares

Hawaii is part of the Pacific U.S. Census division, which has the highest renovation resale returns of the 9 divisions in Roots' valuation model. In practice that means a wood deck addition that returns ~83% of its cost nationally typically returns ~97% for a Hawaii home.

The same regional adjustment applies across the division (Hawaii plus AK, CA, OR, WA). Nationwide, the spread for this project runs from ~68% in the West North Central division to ~97% in the Pacific division. See the national breakdown for every region.

The Pacific market

The Pacific division carries the highest home prices and the strongest renovation returns in the country. When land and permits are scarce, improvements to an existing home capture more value. California's ADU-friendly legislation has also made added units a mainstream investment rather than a niche one.

Mild coastal climates make outdoor space usable nearly year-round, effectively extending the home's living area.

Protect the value you add

Whatever the project returns on paper, condition decides what you actually get: in Roots' model the value of completed work fades as it ages, and a documented maintenance record helps a home sell closer to asking. If you're planning around resale value, start with upkeep. The free maintenance checklist generator builds a seasonal schedule for Hawaii homes in about a minute.
