Engineering Hawaiʻi's Spaces
From restaurant permits to high-rise sprinkler compliance, LOFTE delivers stamped, permit-ready mechanical, plumbing, and fire-protection design across Oʻahu — fast, and under one stamp.
Three kinds of buildings. One engineering partner.
Every project starts with a trigger — a renovation, a violation, an ordinance deadline, or failed equipment. We turn that trigger into a permit-ready solution.
Restaurant owners & operators
Kitchen hoods, HVAC, grease waste, and fire-protection scope — stamped for permit, without resubmittal cycles.
Boards & general managers
Navigate the high-rise sprinkler ordinance with an evaluation, options, design, and a defensible reserve number.
New high-rise & affordable housing
Ground-up high-rise and affordable housing developments — mechanical, plumbing, and fire-protection design coordinated from concept through permit.
Mechanical, plumbing & fire-protection engineering — under one stamp.
HVAC & Mechanical Design
Air conditioning, ventilation, and exhaust engineered for comfort, code, and permit approval.
Plumbing Design
Water, waste, grease, and gas systems — including drain, waste, vent and water piping stacks — designed to Hawaiʻi code.
Fire Sprinkler & Fire Protection
Sprinkler and fire-protection design for high-rises, restaurants, ADUs, and code-driven upgrades.
Code Compliance & NOV Resolution
Resolve Notices of Violation that require a licensed mechanical engineer — quickly and defensibly.
Equipment Replacement
Engineered replacement of chillers, fans, air handlers, cooling towers, boilers, pumps, water heaters, and drain, waste, vent & water piping stacks.

Every service written around your trigger event, from evaluation to permit.
Permit-savvy engineering, built for how Hawaiʻi actually builds.
One stamp, fewer cycles
Mechanical, plumbing, and fire protection coordinated under a single licensed stamp — fewer resubmittals through DPP.
Responsiveness that moves permits
Emergencies — NOVs, failed equipment — happen fast. We respond fast, because a stalled permit costs real money.
Local code fluency
Deep familiarity with Honolulu's ordinances and DPP process, from restaurant build-outs to the high-rise sprinkler mandate.
The sprinkler-ordinance decision every Oʻahu board is facing.
Honolulu's fire-safety ordinance pushes older residential high-rises toward life-safety evaluation or a sprinkler retrofit. We help boards understand their options and plan reserves around a defensible number.

Questions Oʻahu owners & boards ask us.
Straight answers to the questions people (and AI assistants) ask about engineering, permits, and Hawaiʻi code.
Usually, yes. Restaurant build-outs and renovations on Oʻahu commonly require stamped drawings for the kitchen exhaust hood, HVAC, grease waste, and fire-protection scope before DPP will issue a permit. LOFTE provides all of it under one stamp to avoid resubmittal cycles.
It requires older residential high-rises that haven't passed a life-safety evaluation to either comply or commit to installing fire sprinklers, on a phased timeline. Hundreds of Oʻahu buildings face this decision. We guide boards through evaluation, options, design, and budgeting. (Confirm current deadlines with the City & County of Honolulu.)
Often, yes. Code can pull fire-sprinkler design into certain new dwellings, ADUs, and large additions — usually discovered mid-permit. We offer flat-fee, fast-turnaround residential sprinkler design to keep your permit moving.
NOVs are time-sensitive. We prioritize them: evaluate the condition, prepare stamped corrective drawings, and work the resolution through the authority to bring the property back into compliance as quickly as possible.
