Elevator Modernization in Seattle, Washington

A Seattle elevator modernization is an alteration under the Seattle Building Code, so it needs an SDCI conveyance permit before work starts and a city acceptance inspection before the car returns to service. We scope partial or full modernization, apply for the permit, and coordinate the inspection, as a licensed Washington elevator contractor.

When modernization is the right call, and when it is not

Age alone is not a reason. The reasons that hold up are parts that can no longer be sourced, repeated failures of the same subsystem, a controller only one company can service, and code items the building cannot meet with the existing equipment. If none of those apply, we will tell you to wait and write down what to watch for. That recommendation costs us work, which is why it is worth something.

Partial or full

Partial modernization replaces the parts causing the problems, usually the controller, drive, door operator, fixtures and emergency communication, and keeps sound machines, rails and structure. Full modernization replaces nearly everything but the rails and structure. In an occupied Seattle office or residential building, partial work done in stages is often what keeps one car running while the other is down.

The Seattle permit and inspection path

1. Scope and equipment selection. We specify the work and the equipment. For modernization we represent Smartrise, GAL and Innovation, and we disclose that when we recommend equipment.
2. SDCI conveyance permit. Required to install or alter a conveyance under SBC 3006.1 and 3006.2. The contractor applies, holding a Washington elevator contractor license and a Seattle business license. The city states most permits issue within 14 business days.
3. Installation. Staged where the building needs a car in service.
4. Acceptance inspection and tests. Performed before the equipment returns to service, with a city inspector.
5. Certificate of inspection. Required to operate under SBC 3009.1, posted in the machine room, control room or management office.

Code edition and what it means for your project

Seattle adopts ASME A17.1-2019/CSA B44:19 with city amendments (SBC 3003.1). The current elevator provisions of the 2021 Seattle Building Code took effect November 15, 2024 under Ordinance 127108. An alteration brings the altered equipment up to the code in force when the permit is issued, so the scope has to be written against the current Seattle provisions, not the edition the building was built under.

Seattle also requires quarterly firefighters’ service tests and annual shunt-trip tests (SBC 3028.5 and 3028.6). A modernization is the right time to make sure the new equipment and the building’s fire alarm interface support both cleanly.

What drives the cost of a Seattle modernization

We do not publish a price, because two buildings with the same elevator count can differ by a wide margin. These are the factors that move a proposal, so you can compare bids on substance:

• Scope. Controller and drive only, or doors, fixtures, machine, cab and hoistway equipment as well.
• Number of cars and stops. More stops means more door equipment and fixtures.
• Traction or hydraulic. Hydraulic work may include the power unit, valve or cylinder.
• Code items triggered by the alteration. Altered equipment is brought to the code in force, which can pull in firefighters’ service, door protection and communication items.
• Building systems. Fire alarm interface, emergency power and machine room conditions.
• Outage plan. Staging car by car in an occupied building takes longer than a single shutdown.
• Cab work. Optional cab interior work is often bundled; ask for it priced separately.

Managing the outage in an occupied Seattle building

The hardest part of a modernization is usually not the equipment. It is the months tenants spend with one fewer car. Starting alteration work takes the car out of normal service until the city’s acceptance inspection, so the outage plan belongs in the proposal, not in a phone call after signing. Ask every bidder how they will stage the cars, how long each car is expected to be down, what happens if a part arrives late, and how residents with mobility needs will be accommodated. We write those answers into our proposals.

Why owners call an independent

We are not a branch or dealer of Otis, KONE, Schindler or TK, and we are not trying to move your building onto a proprietary platform. Our goal is equipment more than one company can maintain after we leave, so your next maintenance contract is a real choice.

PDX Elevator Safety holds Washington Elevator Contractor License PDXELES742KK (license type LC, specialty All Areas) and Washington contractor registration PDXELES741KJ, both issued by the Department of Labor & Industries. You can confirm both at the L&I Verify a Contractor tool before you hire us, and you should do the same for anyone else you are considering.
