Trinity Lawn Care.

The state insures Trinity Lawn Care under a single workers'-comp class, lawn care maintenance, and that matches what the company advertises: aeration and power raking, herbicide application, shrub and minor tree trimming, fall and spring clean-ups, hauling, and light installation of rock, bark and sod. The state puts the crew at one to three people, with the owner working on the jobs. Michael Yost and Michael Hansen have been listed as principals since 2015, and Leslie Gilbert and Michael Gilbert were added in 2026. The company works around Spokane, within roughly 25 miles of its base. This is a maintenance outfit with a narrow focus, a good match for a homeowner who wants the same small crew back every week, plus help with the spring aeration and the October leaf pile. Sod or a fresh bark bed on a residential lot fits the work mix well. A large commercial property, a retaining wall and patio project, or a new irrigation system designed from scratch is a different kind of job, better suited to a firm built around hardscape or irrigation design. Most lawn care in Spokane needs no permit at all, but the edges of this trade can. New irrigation tied into a home's water supply usually involves a backflow prevention device, which the City of Spokane and surrounding water purveyors require to be installed and tested. Grading that changes drainage toward a neighbor, or retaining walls past a modest height, can also draw a permit in Spokane or Spokane County. When a job crosses into that territory, expect the contractor to pull the permit and schedule the inspection, since they're the one answerable for the work.
