Three Index rules to settle before a remodel is drawn

  1. The Index rule

    Rockfall, slides and avalanches

    Index designates geologically hazardous areas town wide, whether or not they have been mapped: erosion, landslide, seismic, mine, rockfall, flooding and volcanic hazards. Land within a 22-degree shadow angle from the base of a rock source counts as a suspected rockfall area, and signs of snow avalanches also mark a landslide hazard. A site listed in the town's critical areas map folio for one of these hazards needs a detailed study for that hazard; volcanic risk alone does not.

    What we do

    Before design starts, we check your address against the town's critical areas map folio for rockfall, landslide and avalanche listings.

  2. The Index rule

    The North Fork Skykomish

    The North Fork Skykomish River is a shoreline of statewide significance, and the town's Shoreline Master Program reaches 200 feet landward of its floodway edge or ordinary high water mark, whichever lies further inland. Inside that band the shoreline setback is 25 feet in the Shoreline Upland and Armored Bank environments and 35 feet in Urban Conservancy. In a mapped flood zone with a base flood elevation, a new or substantially improved home needs its lowest floor at least one foot above that elevation.

    What we do

    We check your lot against the shoreline environments map and the flood insurance rate map before any addition or deck is drawn.

  3. The Index rule

    One counter, several clocks

    Permit applications are filed with the town clerk at Index Town Hall. The town has up to 28 days to decide whether an application is complete and 120 days after that to issue a decision, and when outside planners or engineers review a project, the applicant reimburses those costs. Work that is not exempt from the critical areas code also needs the town's critical area forms, signed and notarized, before the permit is considered.

    What we do

    We prepare the drawings and the notarized critical area forms and file them with the town clerk as one complete application.

Each of these is answered on paper with the town before a crew is scheduled.

Volcano did a master bath remodel for us. The project was completed efficiently and on time. All of their workman were courteous and hard working. When we had a couple of material delivery delays they kindly adjusted their schedules. Their pricing was fine and the terms of the contract were fulfilled. We highly recommend Volcano Building.

Bar Unger, founder of Volcano Builders

I'm Bar, founder of Volcano Builders. I have been building for 20+ years, and our main office is in Bellevue, a short drive from Index. Most remodeling problems start before any work does: a vague price, a missed permit step, nobody answering the phone. So every project we take on gets a written, itemized price before work starts, a design and permit plan built around your city's rules, and one project manager you can actually reach.

Process

How your Index remodel works

Three steps, one team, and a written price before anyone picks up a tool.

  1. Consultation

    We visit your home, walk the space and talk through your goals and budget.

  2. Design and permits

    We design the project, price it in writing and handle the Town of Index building permit.

  3. Build and hand over

    One project manager runs the build through the final walkthrough.

Guide

Remodeling in Index: permits, the river, hazard ground and water

How a permit moves through Index Town Hall

Applications go on forms provided by the town to the town clerk at Town Hall, and the mayor, with the clerk and anyone the mayor designates, administers the process. The town has up to 28 days to call an application complete, 14 more days after any resubmission, and 120 days from a complete application to a final decision. If the town asks for more studies, the applicant has 90 days to supply them.

When the town uses outside planners, engineers or attorneys to review a project, the code has the applicant reimburse those costs plus a 10 percent administrative fee. The clerk estimates the deposit within 28 days of submission, and the application is not complete until it is paid.

Index builds to the 2021 editions of the International Residential Code and the International Existing Building Code with Washington's amendments, and electrical work follows the edition adopted by the state Department of Labor and Industries.

Building along the North Fork Skykomish

The town's shoreline program sorts land near the river into environments. Shoreline Upland covers the developed lots landward of Avenue A, Armored Bank covers roughly a mile of legally placed rock and riprap along the town limits, and Urban Conservancy protects the more natural stretches. The program's own inventory found that about nine in ten shoreline parcels in Index already have a building less than 20 feet back.

That matters for older riverside houses. A home that sits closer to the water than its environment now allows may still grow, as long as the addition does not push further into the setback; going further needs a shoreline variance.

Flood rules run alongside. The town adopts FEMA's flood study for Snohomish County dated June 19, 2020, requires a floodplain development permit before work in a special flood hazard area, and asks for the lowest floor elevation on the application. In a mapped floodway, rebuilding a house is limited to work that adds no ground floor area or stays under half the structure's market value.

Critical areas: the code rewritten in 2025

Index adopted a new critical areas ordinance on December 1, 2025. It applies to all land in town, and its map folio at Town Hall is a general guide only: the real extent of a wetland, stream buffer or hazard is set in the field by a qualified consultant. The code encourages a pre-application meeting with the administrator, who also visits the property once the forms are in.

The Skykomish River and upper and lower Cripple "Coho" Creek are named fish habitat. The standard buffer is 150 feet for streams that support fish and 100 feet for other streams, and work within 200 feet of a habitat area needs a detailed study.

Some remodels skip this review. Changing an existing structure is exempt when it adds no footprint, does not increase the septic capacity needed and does not add to a nonconformity, so many interior kitchen and bathroom projects stay outside the critical areas process.

Septic, town water and room to grow

Every building lot in Index's residential zone must be approved by the Snohomish County health district for its on-site sewage system, and buildings keep the county's required distance from every part of the septic system. The minimum buildable lot is 7,000 square feet, except for lots held in single ownership before 1996.

Water comes from the town system, which runs under state water right Certificate 6450. An application for a new or upgraded service goes to the clerk, and the mayor may deny one that would well exceed standard residential use. A second unit or a large addition therefore starts with the water question as well as the septic one.

For accessory dwelling units, state law (HB 1337) lets a city prohibit them on lots not served by public sewers. The regional planning council's review of the town's 2015 plan also noted that physical constraints make new housing on Index's remaining land unlikely, so the answer for any one lot comes from the site itself.

Old houses, seasonal cabins

The Census Bureau's 2020 to 2024 survey puts the median home in Index at 1947, and counts roughly 38 of about 89 homes as built in 1939 or earlier. Nearly all are detached houses, and most of the homes counted as vacant are held for seasonal or occasional use. For a town this small the margins of error are wide, but the picture is of many prewar houses and cabins.

Houses of that age often hide older wiring, framing and plumbing behind the walls. We price that possibility into the written estimate rather than finding it midway through the job.

Questions

Index remodeling questions, answered

Where do I apply for a building permit in Index?

With the town clerk at Index Town Hall, on application forms the town provides. On our projects we assemble the drawings and any critical area forms and submit them, then track the application through the town's review.

How long does the town take to review an application?

The code gives the town up to 28 days to decide whether an application is complete and 120 days from a complete application to a final decision, with the clock paused while the applicant supplies requested information. We plan the schedule around those published limits.

Does an interior kitchen or bathroom remodel trigger critical areas review?

Often not. The critical areas code exempts changes to an existing structure that add no footprint, need no more septic capacity and do not add to a nonconformity. The building, plumbing and mechanical permits still apply.

My house is close to the river. Can I still add on?

Possibly. Inside the 200 foot shoreline band, a home already closer to the water than its environment allows may be expanded if the addition does not reach further into the setback, and flood zone rules set the height of any new floor. We check both maps for your lot first.

Can I add an accessory dwelling unit in Index?

It depends on the lot. The town code defines an ADU as an independent unit within the main house, every lot needs county health district approval for its septic system, and new or upgraded water service needs the mayor's approval under the town's limited water right. We confirm those three answers before any design work.

What will a home remodel in Index cost?

It depends on the scope and on what the house needs once it is opened, and an older house or a project needing outside review adds steps. You receive a written, itemized price before work starts, and typical ranges by project type are in our Remodeling Pricing Guide.
