How Much Does a Home Renovation Cost in Hawaii in 2026

Hawaii carpenters earned a mean $42.06 an hour in May 2025, against $31.55 nationally (BLS). The Remodeling 2025 Cost vs. Value Report (www.costvsvalue.com) puts a midrange minor kitchen remodel at $28,458, a U.S. figure. Hawaii’s $1,500 small-job exemption from contractor licensing ends wherever a building permit is required.

Zonda’s kitchen and bath numbers carry no Hawaii line

Zonda Media’s report sets the 2025 cost of 28 remodeling projects against their resale value in 119 U.S. markets. The report’s defined midrange minor kitchen remodel costs $28,458 as a national average, adds $32,141 in resale value and recoups 113%. Its defined midrange bath remodel runs $26,138, returns $20,915 and recoups 80%.

What Hawaii carpenters earn (BLS, May 2025)

The Bureau of Labor Statistics estimated 4,810 carpenters on Hawaii payrolls, with mean pay of $42.06 an hour ($87,480 a year) and a median of $41.00. Nationwide the mean was $31.55 and the median $29.12. Self-employed carpenters are excluded. A wage is not a job price, only one input to a contractor’s bid.

HRS chapter 444: who may take the job, and where $1,500 stops counting

HRS § 444-9 bars anyone from acting or advertising as a general engineering, general building or specialty contractor unless licensed under chapter 444 and the Contractors License Board’s rules. Section 444-2 lists ten exemptions. The small-job one, paragraph (4), covers a project whose aggregate contract price for labor and materials is not more than $1,500. It never applies where a building permit is required, nor to a piece of a larger project, nor to work split into contracts of $1,500 or less to evade the chapter. Among the others: employees paid wages only, installers of finished products that don’t become a permanent fixed part of the structure, and owner-builders (full list: § 444-2).

Check a license through the Contractors License Board.

Running your own remodel: the owner-builder exemption

Section 444-2.5 frees owners or lessees from licensing when they build or improve residential or farm buildings for their own use, or for a grandparent, parent, sibling or child, and don’t offer them for sale or lease. Its five provisos:

1. register with the county as § 444-9.1 provides;
2. electrical and plumbing work reserved to licensees stays outside the exemption, unless the owner holds that license under chapter 448E;
3. the owner supervises, hires appropriately licensed subcontractors, has licensees do the electrical and plumbing, deducts FICA and withholding taxes and carries workers’ compensation for unlicensed helpers (legally the owner’s employees), and keeps the work within all laws, ordinances, building codes and zoning;
4. until completion, the permit application, the permit, all contracts naming the workers, and proof of payment stay open to immediate inspection by the department;
5. afterward, those records are kept three years and produced within seven business days of a department request.

A sale, lease or offer to sell or lease within one year after completion (the county’s final inspection approval) is prima facie evidence the work was for sale or lease, except a sale or lease to the owner’s employees, permitted work valued under $10,000 on the permit, or an unforeseen hardship the board accepts. Owner-builders cannot recover from the contractors recovery fund. A first violation draws a fine of up to $5,000 or 50% of the permit-application value, whichever is greater; later ones, $10,000 or 60% (§ 444-23(e)). Hardship applications, a three-year ban on violators (anyone who obtains an exemption from the § 444-9 licensing requirement more than once in two years is rebuttably presumed a violator) and agricultural buildings needing no permit are also in the section.

Before you sign: HRS § 444-25.5

By the time a homeowner signs for home construction or improvements, the licensed contractor must have explained out loud, in detail, everyone’s lien rights, plus the homeowner’s option to demand bonding, what a bond protects and its approximate expense, and disclosed whatever else board rules require. The written contract needs both signatures before work starts and notice of the contractor’s right, under § 672E-11, to resolve alleged construction defects before any lawsuit. Condominium and cooperative unit owners and lessees count as homeowners, owner-builder status notwithstanding. A violation is deemed an unfair or deceptive practice, subject to chapter 480 and to chapter 444.

HAR § 16-77-80 sets nine contract contents, among them license number and classifications, the exact dollar amount due, the start date and days to complete, and subcontractors’ names and license numbers (full list: § 16-77-80(a)). Service-type work needing no county permit falls outside both the rule and § 444-25.5.

General excise tax on a contracting job

Hawaii taxes the contractor, not you: HRS § 237-13(3)(A) levies 4% of a contracting business’s gross income, and the City and County of Honolulu and the counties of Hawaii, Kauai and Maui each add a 0.5% surcharge through December 31, 2030, according to the Department of Taxation. A contractor may pass the tax on but need not; if it does, 4.7120% is the maximum pass-on rate.

Hawaii remodeling questions

Can an unlicensed handyman retile my shower?

Only if the whole job, labor plus materials, is $1,500 or less, needs no building permit, and is not part of a larger project or split up to evade the chapter (§ 444-2(4)), unless another § 444-2 exemption covers that person.

I’m fixing up my house and may sell next year. Can I be the owner-builder?

Not if you are building to sell. A sale or an offer to sell within one year after final inspection is prima facie evidence of that, outside the three exceptions in § 444-2.5(b).

Do the contract rules cover my condo unit?

Yes. Section 444-25.5(c) counts condominium and cooperative unit owners and lessees as homeowners.
