FAQ — Remodeling in Seattle
Does Kolmo serve all Seattle neighborhoods?
Yes — every neighborhood within Seattle city limits, from Ballard and Magnolia in the north to West Seattle and Beacon Hill in the south.
How does permitting work in Seattle?
We submit all permits through Seattle Department of Construction & Inspections (SDCI). Most homeowner projects (decks, kitchens, bathrooms, ADUs, basements) follow the STFI or full plan-review track. See /permits/city/seattle for fee and timeline detail per project.
Do you do ADUs and DADUs in Seattle?
Yes. Seattle's 2024 ADU ordinance allows up to two accessory dwelling units per lot (one attached, one detached). We handle design, permitting through SDCI, and construction.
How much does a kitchen remodel cost in Seattle?
Seattle kitchen remodels typically run $35,000–$120,000 depending on scope (mid-range refresh to gut + structural). Use our /calculator/kitchen for a real-time estimate based on your lot and scope.
