What foundation work covers

Foundation work in the Denver metro includes footings, stem walls, basement walls, and slabs-on-grade, plus the excavation that makes room for them. Soils and frost depth set the section. A municipally licensed Denver general contractor coordinates the project, design professionals, and licensed specialty trades. Cost is project-specific and depends on soils, depth, and whether the work is new or a repair.

text

Inspections and when drawings are sealed

City and County of Denver Community Planning and Development inspects footing depth and width and watches for setback encroachment at the footing or slab. Work cannot start until permits are issued. If the design exceeds IRC prescriptive limits (underpinning, sister curb, bench footing, basement dig-outs, helical or push piles), CPD asks for sealed drawings and calculations (DBCA 133.2). Phased permits can split foundation from superstructure.

text

Permits and who coordinates the work

Building permits come through CPD e-permits. Denver DOTI reviews Sewer Use and Drainage for excavations, grading, floodplain, and groundwater. Check floodplain at denvergov.org/flood. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades plus the design professionals required for the project.

What buyers should prepare

New house versus repair, basement versus crawl, any soils report, and distance to lot lines.
