What excavation work covers

Excavation in the Denver metro includes foundation cut, site grading, utility trenches, benching, sloping, and shoring when soils or lot-line conditions require it. Neighboring structures, utilities, and the public right-of-way often drive method. A municipally licensed Denver general contractor coordinates earthwork and licensed specialty trades. Cost is project-specific and depends on depth, soils, and protection of adjacent property.

text

When shoring and extra permits show up

Denver CPD commonly treats excavation, benching, or shoring as a separate permit when the cut is more than 4 feet deep, closer than 4 feet to a lot line, or steeper than 1.5 horizontal to 1 vertical. IRC houses follow building-code policy ADMIN 130/131 and DCBC 3307; those details often ride with the residential construction permit, with excavation issued first. Shoring and soils packages are typically sealed by design professionals. Work that abuts the public ROW may need a DOTI excavation bond; shoring that enters the ROW needs a temporary shoring ROW permit.

Permits and who coordinates the work

City and County of Denver Community Planning and Development reviews excavation and shoring. Denver DOTI reviews Sewer Use and Drainage (SUDP) for excavations, grading, floodplain, groundwater, and ROW impacts. The residential permitting guide also calls for DDPHE review on excavations. Check floodplain status at denvergov.org/flood before drawing. 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 for excavation scopes.

What buyers should prepare

Proposed depth, distance to lot lines, any soils report, photos of neighboring structures, and whether the dig will touch the alley or street.

FAQ

Common questions

Do I need a separate excavation permit in Denver?

Often yes when the cut is over 4 feet deep, close to a lot line, or steeper than 1.5 to 1. Houses may include excavation details with the building permit, with excavation issued before construction.

Who handles excavation permits and licensing?

A municipally licensed Denver general contractor coordinates the project and licensed specialty trades. Colorado has no statewide general contractor license.

What is SUDP doing on a dig?

DOTI reviews sewer, storm grading, floodplain, groundwater, and ROW impacts for excavations. It is a separate review that typically runs with the building package.

When is shoring required?

When slopes cannot be laid back to the allowed ratio, when the cut is near a lot line or structure, or when the soils report requires it. Design professionals seal those packages.

What information helps define scope?

Depth, lot-line clearance, floodplain status, existing utilities, and city or county.
