Varies / optionsInteriors come from owner trades, another GC or separately coordinated subcontractors.
09 / Permit coordination
Responsibility for applying, submitting or obtaining permits. Supplying drawings or offering general guidance alone does not establish that responsibility. A stated owner/independent-GC applicant is an express exclusion from this company's application role. An explicit statement that the company handles permitting qualifies; an unnamed legal applicant is then a contract question.

11 / Completion and handoff
An explicit delivered endpoint or handover appropriate to this company's business role: documents, supplied materials, constructed shell or finished home. A positive status does not imply occupancy-ready delivery. State the actual endpoint. Generic completion language without a defined deliverable or handover remains unresolved.
Classic Buildings ↗
AdvertisedThe process specifies a final 71-point inspection; the inspected work depends on the selected contract.
Cleary Building Corp. ↗
AdvertisedThe material-only responsibility document describes delivery and unloading; this is a supply endpoint, not home occupancy.

Varies / optionsA weather-tight shell is an explicit endpoint; further move-in completion is a different arrangement.

Revolve Construction ↗
AdvertisedThe explicit core endpoint is an insulated weather-tight shell ready for interior trades.
12 / Warranty terms
An advertised duration and identified covered work or component, with limits retained. A generic assurance or unexplained duration without identifiable coverage does not establish terms; a positive status is not verification of the complete warranty contract.
Classic Buildings ↗
Not establishedMaterial-duration marketing does not establish an operative whole-project warranty.
Cleary Building Corp. ↗
AdvertisedThe material-only page advertises a lifetime paint warranty. This is component coverage, not a whole-building or residential workmanship warranty; full terms need confirmation.

Revolve Construction ↗
AdvertisedThe company lists St. Louis and advertises regional Missouri/Southern Illinois construction.
Use the record as a question for the proposal.
Advertised means a source expressly names a responsibility or deliverable. Expressly excluded requires a clear exclusion; varies requires an identified option or scope difference. Not established means the reviewed sources leave the question unsettled. It does not mean the company cannot do the work. Broad full-home language does not fill individual responsibility fields.
The sample is selected, not a local census. One company may appear in several markets and has one shared record. Geographic evidence may be a local base, named service area, project or broad state claim; the market page preserves that distinction. A company page does not establish independent project verification, a license, insurance, current availability or acceptance of the reader’s parcel.
Sources are company-controlled and may be uneven in detail or accessible only through a cached reader. Review dates are not service-change dates. These disclosure counts do not refresh Google inputs, registry records or any historical KC score. Read the cross-market method and counts, ranking method and full downloadable evidence.
