Deck Building in Glendale, CO

Glendale packs its housing stock into a footprint of a little over half a square mile, ringed entirely by Denver, with yards that run smaller and closer to neighboring structures than in most Front Range suburbs. A deck here is often working with less setback room than a comparable project a few miles away, and it is permitted by a city department that runs its own rules independent of Denver on every side. We plan Glendale decks around that tight geometry and around what the city has actually published, rather than importing a generic suburban deck checklist.

City Licensing and Valuation-Based Fees Apply the Same as Every Other Trade

A residential deck in Glendale follows the same city-wide framework as a kitchen remodel or a reroof: a City of Glendale contractor license is required before a permit is pulled, and a license from a neighboring city does not qualify a contractor to work in Glendale. The contractor license application and the permit application can be filed together, reviewed at the same time, and paid as one combined transaction — we file both together so a deck project is not stalled on a licensing step that could have moved with the permit itself.

Fees follow the same valuation-based structure published for every Glendale permit: plan review at 65% of the permit fee, a use tax calculated as valuation times 0.6 times 0.0375, and an Arapahoe Open Space Tax calculated as valuation times 0.6 times 0.0025. We build those two tax line items into a deck budget from the start, since a full deck rebuild carries enough valuation for the percentage to be noticeable.

A Glendale-Specific Permit Trigger by Height or Attachment Was Not Found

Some cities publish a rule exempting a low, detached platform deck from permitting while requiring a permit for any deck attached to the house or built above a certain height. We looked for that kind of Glendale-specific trigger and did not find one on an official city page. Rather than assume a small deck is automatically exempt, we confirm the permit requirement for the specific design — height above grade, attachment to the house, and footprint — with the Building & Permits Department before finalizing plans.

Deck construction otherwise falls under the city’s adopted 2024 International Residential Code, applied through Glendale Municipal Code Chapter 15.04, the same code basis that governs framing and roofing citywide.

Footing Depth and Guard Figures Are Not in a Published Glendale Deck Guide

Glendale has not published a standalone deck-construction bulletin with its own footing depth, guard height, or stair-rail figures the way some cities do. Those numbers fall under the adopted 2024 IRC rather than a Glendale-specific document, and we did not find a citizen-facing Glendale page stating the exact frost depth a footing must reach in this jurisdiction. We are not willing to publish a footing-depth number sourced from a contractor blog or a nearby-county estimate as if it were Glendale’s own figure — we confirm the current required footing depth, along with guard-height and baluster-spacing requirements, with the Building & Permits Department before excavation, and we design to whatever figure the office confirms for the address.

This matters more than it might elsewhere, because a footing poured to the wrong depth on a small Glendale lot is expensive to relocate — there is often no extra yard space to shift a deck a few feet and start over.

Deck Placement Follows Glendale’s Site-Specific PUDD Zoning

All property in Glendale is zoned Planned Unit Development District under Title 17, which the city states lets the Planning Commission review development on a site-by-site basis rather than through a fixed setback table by district. That means the buildable area for a deck on one Glendale parcel is not automatically the same as on a similar-looking lot nearby — the applicable setback can be tied to that specific property’s approved site plan. We confirm the buildable envelope for the address with Planning & Development before laying out ledger attachment points, stairs, or a landing, rather than measuring only off the existing patio or fence line.

Where a deck project sits near the mapped Cherry Creek floodplain, Glendale’s code requires a floodplain development permit before a structure is altered within that area — a real consideration for any Glendale property backing to the creek corridor.

Inspections Skip Fridays and Cluster Specialty Trades on Two Days

Once a deck permit is active, inspection requests must be submitted by 3:30 p.m. the day before the requested date, and the department is not currently performing inspections on Fridays. A deck with new exterior electrical — outlets, lighting, or a hot-tub circuit — runs into the added rule that electrical and low-voltage inspections are scheduled only on Tuesdays and Thursdays.

We schedule footing inspections before backfill and framing inspections before decking material covers the joists, timed to those fixed days, and we request each one before the 3:30 p.m. cutoff so a small scheduling miss does not sit the crew idle for several days waiting on the next available window.

How We Sequence a Glendale Deck

We start by confirming the buildable envelope with Planning & Development given the property’s PUDD status, confirming the permit requirement and footing/guard figures with the Building & Permits Department, and filing the permit and contractor license together with a complete plan set.

Once the permit is issued, we request a Colorado 811 utility locate at least two business days before excavation, dig and pour footings to the confirmed depth, and schedule the footing inspection before backfill covers the work. Framing, guards, and stairs follow, coordinated so rail post locations are set before decking closes over the joists, with electrical work timed to a Tuesday or Thursday inspection slot. A final inspection closes the permit once decking, guards, and stairs are complete.

Common Questions

Does every deck in Glendale need a permit?
We did not find a Glendale-specific rule exempting a low or detached deck from permitting. We confirm the requirement for the specific design — height, attachment, and footprint — with the Building & Permits Department before finalizing plans.

How deep do deck footings need to be in Glendale?
Glendale has not published its own footing-depth figure in a citizen-facing deck guide. We confirm the current required depth with the Building & Permits Department for the specific address before excavation rather than relying on a figure from a nearby jurisdiction.

What setback applies to a deck on a Glendale property?
Glendale zones all property as a Planned Unit Development District, so setbacks can be tied to a parcel’s own approved site plan rather than one citywide table. We confirm the buildable envelope for the address with Planning & Development before layout.

Do deck footings need a Colorado 811 utility locate?
Yes. Any excavation for footings requires a utility locate request through Colorado 811 at least two full business days before digging, a Colorado state requirement that applies the same way in Glendale as elsewhere in the state.
