Home Additions in Kenmore

Kenmore is an easy drive from TopVolk's King County base — roughly 20 to 25 minutes via SR-522, depending on traffic near Lake Forest Park. Free on-site consultations are typically available within a week of the initial call. The first visit covers a site walkthrough, foundation assessment, rough scope discussion, and a candid read on what the City of Kenmore's permit process will require for your specific project and lot. No commissioned closer involved — Vladislav handles the visit. Call (206) 591-1096 to get on the calendar.

In the 98028 zip code, a room addition (200–300 sq ft, no wet areas) runs $45,000–$75,000. A full detached ADU with kitchen and bath lands at $130,000–$195,000 all-in, including permits and utility connections. A second-story addition comes in at $95,000–$200,000+, depending on whether existing footings need structural upgrades and what finish level you're targeting. The number that matters is the line-item quote produced after the site visit — that's what TopVolk delivers, not a ballpark range. Call (206) 591-1096 to schedule the free consultation with Vladislav and get real numbers tied to your specific project.

Kenmore is an incorporated city, so permits go through the City of Kenmore's Building Division — not King County DPER. A full permit submittal requires a site plan with setbacks and lot coverage calculated, dimensioned floor plans, structural calculations, and energy compliance documentation per the current Washington State Energy Code. Plan review currently runs 6 to 10 weeks for major structural work. Permit fees are based on project valuation and typically run $1,800–$4,500 for additions in the $75,000–$200,000 range. TopVolk prepares the complete permit package as WA Licensed Contractor of record — homeowners don't navigate the city portal solo or track down inspection scheduling themselves. Required inspections include rough-in framing, MEP rough-in, insulation, and final before certificate of occupancy is issued.

Yes — WA HB 1337 (2024) allows up to two ADUs per single-family lot statewide, and Kenmore's zoning now reflects that. A property in the 98028 zip code can have both an attached ADU (AADU) and a detached ADU (DADU) on the same lot simultaneously. The City of Kenmore still requires a full permit submittal with site plan, structural drawings if stick-framed, and utility connection details. Side and rear setbacks for a DADU are typically 5 feet, height is capped at 24 feet, and lot coverage limits still apply — smaller lots may constrain the DADU footprint significantly. A 400–500 sq ft DADU with kitchen, bath, and separate entrance runs $130,000–$175,000 in the current Kenmore labor market. Call (206) 591-1096 to talk through your specific lot constraints with Vladislav.

TopVolk provides a one-year workmanship warranty on all addition projects — covering framing connections, roofing installation, siding, windows, and interior finish work. Structural components follow manufacturer terms: engineered lumber products like LVL beams typically carry 25–50 year manufacturer warranties. Window coverage is product-specific; Milgard and Pella both offer transferable limited lifetime warranties on their vinyl and fiberglass lines, which matters if the home sells within a few years of the project completing. The contract also includes a deadline penalty clause — if TopVolk misses agreed project milestone dates, financial penalties are written into the agreement. That's not standard practice in this industry; it's a specific commitment Vladislav makes on every project.

TopVolk serves the full Seattle Metro — King, Snohomish, Pierce, and Kitsap counties. From Kenmore, that means regular work in Bothell, Kirkland, Redmond, Shoreline, Woodinville, and Mountlake Terrace. Scheduling for addition projects typically runs 2 to 4 weeks out for initial consultations, depending on current project load. For Kenmore homeowners specifically, access via SR-522 makes site visits easy to coordinate — whether the property is near Saint Edward State Park or along the Lake Washington waterfront. Call (206) 591-1096 or schedule directly with Vladislav to check current availability.
