Coverage · St. Louis Metro

Areas Served

Two offices — Chesterfield and Clayton — covering St. Louis County, St. Charles County, the City of St. Louis, and the communities beyond. A Missouri-licensed P.E. on every site visit.

Offices by appointment

Two offices,
one metro.

Chesterfield covers the west side of the county. Clayton covers central, south, and the city. Whichever is closer sets the drive — the engineer, the report, and the stamp are identical either way.

Why the address matters

Local knowledge
shortens the permit.

01 · Plan review

One county, many review desks

St. Louis County reviews most unincorporated work, but Chesterfield, Clayton, Kirkwood, Webster Groves, Ballwin and a dozen other municipalities run their own building departments with their own submittal standards. Drawings are formatted for the desk that will actually open them — which is why most of our sets clear plan review on the first pass.

02 · Soils

Expansive clay, west to east

West County subdivisions sit on clay that swells in a wet spring and shrinks in an August drought, moving footings a fraction of an inch every season. Closer to the river, the fill and bedrock story changes completely. The same crack means two different things depending on which side of the county it sits on.

03 · Housing stock

Post-war ranches, century-old brick

A 1968 split-level in Chesterfield and a 1912 brick four-square in Clayton fail in entirely different ways — truss-framed roofs and undersized headers in one, unreinforced masonry and notched joists in the other. Knowing the era of the neighborhood tells us what to look for before we open the crawlspace.

Every service, either city

Eight service lines,
on both sides of the county.

Engineering, architectural design, and inspection are delivered from both offices. Pick the city closest to the property to see the services written for that jurisdiction.
