Quick answer

The short version

5 key points
  • Start with your declaration, bylaws and house rules. They spell out what AC types are allowed, where condensers can go and what needs board approval.
  • Most associations require a written alteration request with equipment specs, a layout drawing, condensate and electrical details, and proof of a licensed, insured contractor.
  • Hawaii DCCA guidance says associations should require licensed contractors and permits. AC work in Hawaii calls for a C-52 license, and new electrical circuits need an electrical permit.
  • Condenser placement, wall or slab penetrations, noise, condensate drainage and changes to common elements are the most common approval hurdles.
  • Approval times vary by building. Start early, especially if you want AC before the hottest months.

Hawaii Energy instant rebates, program year through 30 June 2027

Taken off your invoice, not claimed later. First-come, first-served while program funds last. Requires a Hawaiian Electric account, so Kauai (KIUC) is not eligible, and the work must be done by a Hawaii Energy Clean Energy Ally except where noted.

What qualifiesRebateCounted
Split AC / mini-splitSet by the outdoor unit's size and SEER2 rating: $450 from 8,000 to under 20,000 BTU at 17.2+ SEER2, which covers 9,000 and 12,000 BTU units (they earn nothing below 17.2); $550 starts at 30,000 BTU. Counted per condenser, so three single-zone systems earn three rebates while one multi-zone earns one. Newly constructed homes do not qualify; newly purchased homes do.$400-$550per outdoor unit (condenser)
Central AC retrofitOld outdoor unit must be 13.0 SEER or lower and the new one 15.2 SEER2 or better. Pre-approval from Hawaii Energy is required before the work starts.$1,250per system

01Quick answer: the condo AC approval process

In Hawaii, a condominium association is often called an AOAO, short for Association of Apartment Owners. Most AOAOs require approval before an owner installs new AC or makes changes that affect the building's exterior, structure, electrical system or common elements.

The typical path looks like this: read your governing documents, talk to your managing agent, get a proposal from a licensed contractor, submit an alteration request with drawings and specs, secure permits where required, then schedule the work with building management once approved.

This guide is general information

Every building's documents are different, and this is not legal advice. Your declaration, bylaws, house rules and managing agent have the final word. For questions about your rights or obligations as an owner, consult your association or an attorney.

02Step-by-step: getting your condo AC approved

Here is how the process usually unfolds in Honolulu buildings, from walk-ups in Makiki to towers in Kakaako.

Step 1: Read your declaration, bylaws and house rules

These documents define what is part of your unit, what is a common element and what needs approval. Many buildings also have written alteration guidelines or an AC policy listing approved system types, condenser locations and contractor requirements. Hawaii DCCA guidance encourages owners to check these documents before starting any project. Your managing agent or resident manager can provide copies.

Step 2: Talk to management early

Ask a few questions before you get quotes: What AC types are allowed? Where can outdoor units go? Are new wall or slab penetrations permitted? Is there enough electrical capacity for a new circuit? Are there work-hour, elevator or insurance requirements? The answers shape what your contractor proposes.

Step 3: Get a site visit and proposal

Have a licensed contractor visit your unit to confirm what your building allows and what your space needs. AC work in Hawaii requires a C-52 Ventilating and Air Conditioning contractor license, and refrigerant handling requires EPA Section 608 certification. You can verify any contractor's license on the DCCA license search.

Step 4: Submit the alteration request

Most buildings use an alteration form describing the proposed work, the equipment and where it goes, backed by supporting documents. The section below lists what associations commonly ask for. A complete package the first time is the fastest route to approval.

Step 5: Get permits when required

Hawaii DCCA guidance says associations should require licensed contractors and permits. With the City and County of Honolulu, new electrical circuits and panel work require electrical permits, and some installations may require a building permit. A like-for-like replacement often does not need a building permit, but check with your contractor and building. Our guide to AC permits in Honolulu covers what triggers one.

Step 6: Board or managing agent review

Some managing agents approve routine requests quickly; other buildings send alterations to a board that meets monthly. Approvals may come with conditions, such as a specific condenser location or an owner agreement to maintain the equipment. Read those conditions carefully before signing.

Step 7: Schedule the installation

Once approved, your contractor coordinates with building management on service elevator reservations, loading dock and parking access, allowed work hours, floor and hallway protection and any water or power shutoffs. Giving neighbors a heads-up about drilling days goes a long way.

03What to include in your alteration request

A complete package is the best way to avoid a second round of questions. Most requests include:

  • A written scope of work describing the equipment and what changes
  • Manufacturer cut sheets showing size, dimensions and sound ratings
  • A simple layout drawing with indoor and outdoor unit locations and line-set routing
  • A condensate plan showing where water drains
  • Electrical details, including any new circuit and disconnect
  • Contractor license information and a certificate of insurance, often naming the association
  • Proposed work dates and hours

04Building rules that commonly cause delays

These are the issues boards scrutinize most:

  • Condenser placement: Many buildings limit outdoor units to lanais, roofs or specific brackets, and some restrict anything visible from outside.
  • Penetrations: Drilling through exterior walls or concrete slabs often needs specific approval. Some high-rises require scanning before any core drilling to avoid tendons, rebar or conduits.
  • Noise: Boards may review sound ratings to protect neighbors, especially for lanai condensers near bedrooms.
  • Condensate: Water must go to an approved drain, not onto a lanai below or down the building face.
  • Electrical capacity: Older buildings may have limited capacity per unit.
  • Appearance: Line-set covers and equipment colors may need to match the building.

05Replacing existing AC vs adding new AC

Replacing an existing system with the same type in the same location is usually the simplest approval, and some buildings handle it administratively. Adding split AC where there was none, moving a condenser or switching from a wall sleeve to a mini-split generally requires the full alteration process.

If your tower uses chilled-water fan coils or water-source heat pumps, replacements must also match the building's system and are coordinated with building engineering.

It varies widely by building. Some managing agents approve routine requests quickly, while others review alterations at monthly board meetings. A complete request with drawings and specs helps avoid delays.

Many Honolulu buildings allow it, often with rules on placement, mounting, noise and drainage. Some prohibit it. Your declaration, house rules and managing agent will tell you what is allowed.

AC work requires a Hawaii C-52 Ventilating and Air Conditioning contractor license, and refrigerant work requires EPA Section 608 certification. Most associations also ask for a certificate of insurance. You can verify licenses on the DCCA license search.

It may. New electrical circuits and panel work require electrical permits, and some installations may need a building permit. We handle permits when required.

In many buildings, the owner is responsible for AC equipment serving their unit, and approvals sometimes include a maintenance agreement. Your governing documents and approval letter spell out the details.
