Custom Homes in Mukilteo

Cost-plus custom home building for Mukilteo and the greater Snohomish County area.

Mukilteo is a waterfront city on Puget Sound, about 25 miles north of Seattle, where a historic Old Town core sits alongside view-driven neighborhoods like Chennault Beach, Harbour Pointe, and Goat Trail. The draw here is consistent across the city: sweeping views of the Sound, the islands, and the Olympics, and a mix of established character homes and newer custom construction.

Real demand, real numbers

The range in Mukilteo runs wide. A view estate at 9716 58th Pl W sold for $4,100,000, while more typical homes still move quickly — 10421 62nd Pl W, in the Chennault Beach community, sold for $1,165,000 in August 2026. Either way, well-built homes on strong lots don’t sit on the market here.

Building in Mukilteo

The City of Mukilteo runs its own Permit Center and Building Official, separate from Snohomish County, with applications submitted online. New construction and additions are also subject to the city’s street-improvement standards — a site-specific factor worth accounting for early, not after a design is finished.

Bluffs and steep slopes

A lot of Mukilteo’s view property sits on or near the bluffs above the Sound. The city treats any slope of 40 percent or steeper with more than ten feet of vertical relief as a geologic sensitive area. Building near one requires a geotechnical report from a licensed professional, a minimum 25-foot setback from the top or toe of the slope, and the slope’s vegetation left in place. A deck that adds no real load, or an accessory building of 120 square feet or less, can come within ten feet. On a view lot, that setback often decides how close the house can sit to the view, so we settle it before design starts.

Trees

Mukilteo’s tree code, updated in 2024, regulates evergreens over 8 inches in diameter and deciduous trees over 12 inches. New development has to keep at least a quarter of the existing significant trees, and removal needs city approval. Where that minimum can’t be met, each tree removed is replaced with one to three new trees, depending on its size.

Near the water

Within 200 feet of the shoreline, the city’s shoreline rules cap a home at 30 or 35 feet, depending on the zone, and lot coverage at 30 to 35 percent. For waterfront lots, those limits and the slope setback together shape the design more than anything else.

How we build

Every Lockie Homes project runs on the same Feasibility and Construction Agreement (FCA) process, regardless of where it’s built: open-book cost-plus pricing, a Bid-Backed Budget built from real subcontractor bids, and a dedicated project manager keeping you informed at every stage.
