Permit Thresholds
Wheat Ridge permit thresholds
- Code reference
- Retaining walls over 4' high (or supporting a surcharge) and other structural elements like decks or room additions explicitly require permits; any structural work in a remodel would qualify as an alteration requiring a permit.
- Code reference
- These requirements are enforced under the City of Wheat Ridge Municipal Code, Chapter 5, Article II, Division 2 (Building Permits).
- Use tax
- Per City Code Section 22-68, use tax is charged at 3.5% of 60% of the project valuation (60% of valuation is assumed to be materials subject to tax).Section 22-68
- Code reference
- Permit fees are based on the higher of the applicant’s valuation or the building official’s minimum (using ICC Building Valuation Data); a separate plan review fee (65% of the permit fee) applies where required.
Codes are amended regularly — verify current requirements with **City of Wheat Ridge Building Division (City of Wheat Ridge, Colorado) issues residential building permits.
Energy Code
Wheat Ridge energy code quick facts

Excavation built around Denver conditions
Excavation sets the base for foundations, utilities, drainage, hardscaping, and pools. In the Denver metro area, that work has to account for expansive clay soils, precise depths and slopes, protection of adjacent property, and City & County of Denver permit and inspection rules. As a municipally licensed Denver general contractor, we coordinate excavation with geotechnical recommendations, specialty trade partners, and the overall build sequence so the hole, trenches, and finish grade support what comes next.
text
Typical excavation scope
Common residential and commercial excavation work includes: - **Foundation and basement excavation** — Digging to design depth and removing unsuitable fill or weak soils so the foundation sits on competent bearing ground. - **Trenching and underground work** — Trenches for water, sewer, gas, electrical conduit, and subsurface drains (including French drains), with attention to depth, alignment, and required slope. - **Site preparation and grading** — Clearing vegetation and roots, rough grading to shape the site, and final grading to direct water away from structures. - **Hardscape and pool excavation** — Preparing pads and footings for patios and retaining walls, and excavating pool shapes to plan. - **Over-excavation and engineered backfill** — Removing expansive or unsuitable soils and replacing them with approved non-expansive fill compacted in controlled lifts. - **Shoring, sloping, and benching** — Temporary support or earthwork methods that keep excavation walls stable, especially on deeper digs or work near property lines.

Methods and materials used on Denver sites
Most bulk earthmoving uses mechanical excavation—excavators, backhoes, skid steers, mini excavators, and dozers—for open digs, grading, and mass haul. Hydrovac excavation (high-pressure water plus vacuum) is often preferred around existing utilities, in tight access areas, or where a more precise, less destructive dig is needed. Soil support may involve sloping (walls cut at an angle based on soil type), benching (stepped terraces), or shoring systems such as beams and lagging, sheet piles, braced frames, concrete piers, or tie-backs when walls cannot be laid back. On expansive bentonite-bearing clays common around Denver, geotechnical reports frequently call for over-excavation, engineered granular fill, moisture control, and sometimes lime or cement stabilization or geosynthetic reinforcement. Backfill is placed in thin lifts, moisture-conditioned, and compacted to specified density while protecting buried utilities.

Denver permits, inspections, and code basics
In Denver, excavation permits and inspections are handled through the City & County of Denver Community Planning and Development (CPD) Building Inspection Division, under the Denver Residential Code (DRC), Denver Commercial Building Code (DCBC), and related policies, along with OSHA safety requirements for worker protection. A permit is commonly required for excavations deeper than 4 feet; excavations within 6 feet of a property line without written neighbor permission; slopes steeper than 1.5 horizontal to 1.0 vertical; deeper retaining-wall or fence excavations (other than simple post holes); and work that needs engineered shoring or benching beyond prescriptive limits. Shallower work may be exempt when it stays within depth, setback, and slope thresholds (for example, digs 18 inches or less, or under 4 feet when set back from the property line at least as far as the excavation is deep and slopes are 1.5:1 or flatter). Projects that need shoring often require a geotechnical investigation sealed by a Colorado registered professional engineer, and complex support systems may need engineered designs and calculations. Deeper steep excavations can trigger fencing and access controls, pre-construction meetings with the Building Inspection Division Construction Inspector, posted notices, and in some cases written notice to adjacent owners before work starts. Work abutting public rights-of-way may also involve an excavation bond through the Denver Department of Transportation and Infrastructure. Inspection sign-off is frequently needed before the main structure permit can move forward.

What to evaluate before you hire
Look for a team that understands Denver’s expansive soils and CPD process—not just someone who owns a machine. Useful checkpoints include municipal licensing and ability to coordinate required permits; experience with local geotechnical recommendations; liability and workers’ compensation coverage (and bonding when work touches public ROW); equipment matched to the job (bulk earthwork vs. precision/hydrovac); documented OSHA-minded safety practices; clear scope for export/import of material, over-excavation, shoring, and backfill; and a realistic sequence that protects neighboring property and keeps drainage working during and after construction. Ask how they will handle utility locating, spoils, compaction verification, and inspection hold points before concrete or utilities go in.
FAQ
Common questions
Who handles the excavation permits and licensing?
A municipally licensed Denver general contractor coordinates the work and the licensed specialty trades involved. Excavation permits and inspections in Denver generally run through CPD’s Building Inspection Division. Whether a separate excavation permit is required depends on depth, proximity to property lines, slope, and whether engineered shoring or benching is needed.
When is an excavation permit typically required in Denver?
Common triggers include digs deeper than 4 feet, excavations within 6 feet of a property line without written adjacent-owner permission, slopes steeper than 1.5:1, deeper retaining-wall excavations, and work needing non-prescriptive shoring or benching. Limited shallow work may fall under code exceptions, but the final call follows Denver CPD rules for the specific site.
Why do Denver projects talk so much about expansive soils?
Much of the metro area has bentonite-bearing clays that swell and shrink with moisture. Geotechnical reports often require removing unsuitable soil and replacing it with engineered, non-expansive fill compacted in lifts, along with drainage and moisture control, so foundations and slabs are less likely to heave or settle.
What is the difference between sloping, benching, and shoring?
Sloping lays excavation walls back at a safe angle. Benching cuts those walls into steps. Shoring uses temporary structural support—such as sheet piles, beams and lagging, braces, or tie-backs—when space or depth makes open cut impractical. Deeper or constrained sites often need engineered designs and a pre-construction meeting with Denver inspectors.
When is hydrovac excavation useful?
Hydrovac uses water and vacuum to remove soil with more precision and less risk of damaging buried lines. It is especially helpful near known or suspected utilities, in tight access areas, and where mechanical buckets would be too aggressive.
How does excavation affect neighboring property?
Denver code emphasizes protecting adjacent public and private property. That can mean proper sloping or shoring, fencing and signage on steeper deep digs, notice requirements, and careful control of vibration, spoils, and drainage so adjoining lots and structures are not undermined or flooded.
