Missouri Compliance

Detailed for Missouri, not adapted to it

Missouri projects often face review requirements shaped by local city and county building departments, St. Louis and Kansas City-area submittal standards, frost-depth foundations, basement and crawlspace conditions, storm-prone sites, floodplain documentation near major rivers, and New Madrid seismic considerations in parts of the state. Generic drafting can create plan-review comments, resubmittals, and avoidable permit delays.
Every Cadgency set is prepared with Missouri permitting in mind. We organize plans, elevations, structural notes, schedules, details, foundation coordination, site-specific references, and revision responses so residential, remodel, accessory structure, tenant improvement, and light commercial projects are easier for reviewers to process.

FAQ

Missouri questions, answered

Many structural scopes, additions, garages, tenant improvements, light commercial projects, and certain permit submittals may require a Missouri-licensed professional depending on project type, city, county, site conditions, and local AHJ requirements. Cadgency prepares the drawing set and coordinates sealing when required.

Yes. We prepare Missouri drawings for floodplain sites, basement remodels, crawlspace work, additions, garages, storm repairs, rural structures, tenant improvements, and light commercial permit sets.

Typical residential permit sets run 5 to 10 business days depending on scope, existing information, structural requirements, local review standards, frost-depth foundations, floodplain documentation, basement or crawlspace coordination, and whether zoning or plan-check comments are involved. As-builts and smaller revisions are usually faster.

Whatever you have: sketches, photos, old plans, survey information, floodplain details, foundation requirements, basement notes, or a basic description of what you want to build. We turn that information into a clear Missouri-ready drawing package.
