Timeline

Typical timing

Plan review: 10–15 business days (standard); over-the-counter same-day for eligible simple projects
Total cycle: 3–6 weeks from application to final inspection

Simple fence permits with complete, accurate submittals tend to move faster. Pool-barrier and structural masonry reviews may take longer. Inspection scheduling typically adds 2–5 business days per required inspection. Expedited review may be available for an additional fee on eligible submittals.

Process

How the permit process works

Determine whether your fence requires a permit Check the height and type of your planned fence. Standard wood, vinyl, chain-link, or metal fences 6 feet and under generally do not require a Denver building permit. A permit is required for fences over 6 feet, pool-barrier fences, and masonry walls over 6 feet. Separately confirm that your fence height and placement comply with Denver Zoning Code Section 10.5.5 regardless of whether a permit is required. When in doubt, call Denver CPD at 720-865-2705 or visit permits.denvergov.org.
Check zoning, easements, and overlay districts Confirm your zoning district and any applicable overlay zones using Denver's online zoning map or by contacting Denver CPD. Verify whether your property is in a FEMA Special Flood Hazard Area and check for drainage, utility, or access easements on your plat before placing any fence posts. If your property is in a Denver landmark or historic district, contact the Landmark Preservation Commission before proceeding.
Review HOA and deed restrictions Check your community's CC&Rs or HOA governing documents for fence height, material, color, and design requirements. HOA rules are enforced separately from city permits and are often more restrictive. Obtain HOA approval before starting construction if required by your community.
Prepare plans and supporting documents For fences requiring a permit, prepare a site plan showing lot lines, the proposed fence line, and distances to property lines and structures. Include an elevation drawing with height, material, and post spacing. Fences over 6 feet and masonry walls require footing and structural details. Pool-barrier fences must include gate hardware specifications and a layout showing the compliant enclosure perimeter.
Submit through Denver's online permit portal Create or log in to an account at permits.denvergov.org, select the appropriate residential building permit type, upload your documents, and submit. Simple fence projects may be eligible for over-the-counter (OTC) review at the Wellington Webb Building, 201 W. Colfax Ave., Denver, CO 80202.
Respond to plan review comments Denver CPD reviewers evaluate submittals against the 2021 IRC and Denver Zoning Code. If corrections are requested, update your drawings and resubmit through the portal. OTC projects are reviewed while you wait at the permit counter.
Receive approval and begin construction Once the permit is issued and fees are paid, download and keep the permit card or approval printout accessible at the job site during all phases of construction. Do not begin permitted fence construction before the permit is issued.
Schedule required inspections Request inspections through permits.denvergov.org or by calling the Denver CPD inspection line as construction progresses. Fences over 6 feet and pool-barrier fences typically require a footing inspection before pouring concrete and a final inspection when the fence is complete.
Pass final inspection and close out the permit After the final inspection passes, the permit is closed and the fence becomes part of the official city record. Retain all documentation — it supports insurance claims, title review, and future resale.

What can go wrong

Denver CPD can issue a stop-work order if unpermitted construction is discovered for work that required a permit.
The city may require removal or structural opening of an unpermitted fence at the owner's expense.
Administrative penalties and daily fines can accrue under the Denver Revised Municipal Code until the violation is resolved.
After-the-fact permits for completed fences may require destructive inspection of footings and concealed structural members.
A pool without a compliant barrier enclosure is a serious safety and liability risk; non-compliant pool fences expose homeowners to liability in the event of an accidental drowning.
Homeowner's insurance may deny claims for damage involving unpermitted structures.
Unpermitted or non-compliant fences flagged during a home sale can delay or derail the transaction, and retroactive permitting is more disruptive and expensive than upfront compliance.
Landmark or historic district violations can result in mandatory restoration or removal orders from the Denver Landmark Preservation Commission.

FAQ

Common Austin deck permit questions

Do I need a permit to build a fence in Denver, CO?

It depends on height and type. Most standard wood, vinyl, chain-link, or metal residential fences 6 feet and under do NOT require a building permit from the City and County of Denver. However, a permit IS required for any fence exceeding 6 feet in height, any fence serving as a swimming pool barrier, and masonry walls over 6 feet. Front yard fences are subject to Denver Zoning Code height limits regardless of permit status. When uncertain, call Denver CPD at 720-865-2705.

What is the maximum fence height in Denver without a permit?

In rear and side yards, fences 6 feet (72 inches) and under generally do not require a building permit. In required front yard setbacks, Denver Zoning Code Section 10.5.5 limits solid fences to 4 feet in height and open/decorative fences (at least 50% open area) to 4.5 feet — regardless of whether a permit is required. Exceeding these front yard limits is a zoning violation.

Does a pool fence always require a permit in Denver?

Yes. Any fence or barrier that encloses a swimming pool requires a building permit from Denver CPD. The enclosure must comply with the 2021 IRC Section R326, including minimum height requirements, self-closing and self-latching gates, and specific climb-resistance and spacing standards. Non-compliant pool barriers are a serious safety hazard and a significant liability risk.

How much does a fence permit cost in Denver?

Denver permit fees are based on declared construction valuation. For a typical residential fence requiring a permit, expect roughly $75–$250 in combined permit and plan review fees. Standard fences 6 feet and under typically require no building permit and therefore incur no permit fee. Confirm the current fee schedule at denvergov.org/cpd before applying.

Where do I apply for a fence permit in Denver?

Submit your application online through Denver's permit portal at permits.denvergov.org. In-person and over-the-counter service is available at the Wellington Webb Building, 201 W. Colfax Ave., Denver, CO 80202. You can also call Denver CPD at 720-865-2705 for assistance determining whether your project requires a permit.

What building code does Denver use for fences?

Denver uses the 2021 International Residential Code (IRC) with local amendments under the Denver Building and Fire Code (Denver Revised Municipal Code Chapter 10) for structural and safety requirements. Fence height, location, and design standards are governed by Denver Zoning Code Section 10.5.5 (Fences, Walls, and Similar Structures). Pool-barrier fences must also comply with IRC Section R326.

My property is in a Denver historic or landmark district — do I need extra steps for a fence?

Possibly. Properties in Denver landmark or historic districts (such as Curtis Park, Highlands, or Baker) may require design review or a Certificate of Appropriateness from the Denver Landmark Preservation Commission before constructing or replacing a fence. Contact Denver CPD at 720-865-2709 or visit denvergov.org/landmark for requirements before starting any fence work.

What happens if I build an unpermitted fence in Denver?

For fences that don't require a permit (standard fences 6 feet and under), there is no city permit penalty — though zoning violations for front-yard height limits can still be cited. If your fence required a permit (over 6 feet, pool barrier, or structural masonry) and you skipped it, Denver CPD can issue a stop-work order and require removal or retroactive inspection. Daily fines can accrue, and after-the-fact permits may require opening completed footings. Unpermitted work flagged during a home sale can delay or derail the transaction.
