The homes here

A 1989 house in the trees. Bainbridge housing is newer than Seattle's, a 1989 median against King County's 1983, and far more of it is detached, 78% against the county's 50% (Census American Community Survey 2024 five-year estimates). The typical home is a two-story wood-frame house on a wooded lot with a long drive, a deck and a porch up a few steps, so the first question is whether a main-floor bedroom and bath can be carved from a study or a dining room, or whether a stair lift or platform lift is the answer.

Why start with an assessment. Where every contractor visit costs ferry time, a whole-home safety assessment by a certified aging-in-place specialist or an occupational therapist comes first, so the bathroom, the entry and the stairs are one job and one set of permits rather than three trips.

The bathroom. A late-1980s primary bath has a garden tub and a curbed shower. The bathroom safety remodel that fits is a curbless shower with a linear drain and a bench, grab bars in blocking behind the tile, a comfort-height toilet and non-slip flooring.

Rain, moss and the deck. The Seattle area records 152 days a year with measurable rain (NOAA 1991 to 2020 normals), and a cedar deck under fir trees grows moss fast. The entry job is a covered landing, a ramp or step-free entry with a gritted surface, railings on both sides.

The ferry. Washington State Ferries runs the Seattle to Bainbridge Island route; the road alternative loops through Kitsap County. Island homeowners report longer waits for mainland contractors and bids that include ferry time and freight. Ask each bidder where they are based and how they price the crossing.

Licensing and permits in Kitsap County

L&I registers contractors under chapter 18.27 RCW: a $30,000 bond for a general contractor, $15,000 for a specialty contractor, liability insurance, and no competency test; electricians and plumbers are separately licensed. The only exemption is casual work under $500, and on any residential job of $1,000 or more you must receive the Notice to Customer disclosure before work starts. Check the registration, bond and lawsuit history at L&I's Verify a Contractor tool. Bainbridge Island is its own city and issues its own building permits; write into the contract who pulls them. The Washington page has the full state rule and the $25,000 Homeowner Recovery Fund.

Who pays

Most Bainbridge families pay directly, from savings, a home equity line or siblings splitting the cost: no pre-approval, your choice of contractor, a start date you control. Paying out of pocket covers the tools. Kitsap County Division of Aging & Long Term Care, the Area Agency on Aging, is at 360-337-7068; Community Living Connections at 1-855-567-0252 is the statewide entry point. Northwest Access Fund makes low-interest home modification loans to seniors and people with disabilities. A long-term care policy often includes a capped home modification benefit. Original Medicare pays nothing toward remodeling; for Medicaid, ask the Washington State Health Care Authority what is covered and whether there is a waitlist; veterans should ask the VA about the HISA grant.
