How Denver Handles Historic Preservation: A Practical Guide

Denver maintains 204 local ordinances across all categories, and 2 of those deal specifically with historic preservation. Here is a breakdown of what the city actually requires, what is prohibited, and where Denver falls on the strict-to-permissive spectrum compared to other cities.

HPOZ Rules

DRMC chapter 30 establishes Denver historic districts including LoDo, Curtis Park, Humboldt Street, Quality Hill, and parts of Capitol Hill and Cheesman Park. Exterior alterations need a Certificate of Appropriateness from the Landmark Preservation Commission.

Key details: Approval needed: Certificate of Appropriateness. Issuer: Landmark Preservation Commission. Code chapter: DRMC chapter 30. Demolition delay: Up to one year.

Unpermitted alteration in a Denver historic district violates DRMC §30-6 with stop-work orders, daily fines up to $999, and restoration orders. Demolition without COA can result in mandatory rebuild or fines equal to assessed historic value plus criminal charges.

This is not one of those rules that cities tend to ignore. Denver actively enforces its hpoz rules requirements.

Historic-Cultural Monuments

Owners or community groups can nominate Denver structures as individual landmarks under DRMC chapter 30. Landmark Preservation Commission reviews applications using significance, integrity, and exterior criteria. Designation triggers Certificate of Appropriateness review for exterior changes.

Key details: Eligibility: Thirty plus years old. Final approval: Denver City Council. Exterior review: All changes need COA. Tax credit: Up to thirty percent.

Demolition or alteration of a designated landmark without COA violates DRMC §30-6 with daily fines up to $999, restoration orders, and possible misdemeanor charges. Tom's Diner-style demolition battles demonstrate the lengthy hearing process before any change.

This is not one of those rules that cities tend to ignore. Denver actively enforces its historic-cultural monuments requirements.

The Bottom Line

Denver is tougher than many cities when it comes to historic preservation. Out of the 2 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Denver, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Denver's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
