Custom Homes on Lake Roesiger

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

Lake Roesiger sits in the Cascade foothills about seven miles east of Lake Stevens. At 348 acres across three connected basins, it is the third-largest natural lake in Snohomish County, ringed by a mix of older cabins, year-round homes and newer construction, with forested acreage rising on the hills behind the shore.

Real demand, real numbers

Summer 2026 sales show where the value sits. 117 NW Lake Roesiger Road sold for $1,607,750 in August 2026, and 113 NW Lake Roesiger Road, a home of about 1,200 square feet, sold for $1,250,000 in July 2026. When a modest house brings that price, most of it reflects the lot.

Building at Lake Roesiger

Lake Roesiger is in unincorporated Snohomish County, so homes here are permitted through the County’s Planning and Development Services rather than a city building department.

Building on the shoreline

At 348 acres, Lake Roesiger is a shoreline of the state under Washington’s Shoreline Management Act. Anything within 200 feet of the ordinary high water mark falls under Snohomish County’s Shoreline Management Program. A single-family home built for its owner is generally exempt from a shoreline substantial development permit, but it still has to meet the program’s buffer and vegetation standards, and the County confirms the exemption in writing before it issues the building permit. Docks and other work at the water’s edge are reviewed separately, under the shoreline program and state fish and wildlife rules. On a lake lot, those standards and the side setbacks together often decide the size and position of the house, so we work them out before design starts.

On the water

Gas and electric boats and water skiing are allowed on Lake Roesiger. The County park on the southeast shore and the state boat launch at the south end bring summer activity, which is worth weighing when siting a house, a dock and outdoor living spaces.

Hillside lots

Where a parcel has slopes of 33 percent or steeper, or such a slope lies within 200 feet of the planned work, the County requires a geotechnical engineer to evaluate it. A landslide hazard area includes land back from the top of a slope as far as the slope is tall, and building inside one takes a geotechnical report, County-approved mitigation, and a covenant recorded on the title before permits are issued. On a sloped lot, that line can set the buildable area, so it is mapped before the design is drawn.

Water and septic

Water and wastewater are lot-specific here. Some properties connect to a small community water system; others rely on a private well. Where a new permit-exempt well is needed, the County limits it to 950 gallons per day on an annual average, reducible to 350 in a drought, requires a water-use covenant recorded on the title, and expects stormwater handled on site with low-impact development methods. Septic design is part of the early site work, and both shape the budget from the first conversation.

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.
