Got an Unpermitted Structure Notice in Denver?
Here's How to Fight It.

Understanding Unpermitted Structure Violations in Denver

Code enforcement officers in Denver, CO regularly patrol neighborhoods and respond to neighbor complaints regarding sheds, decks, additions, or outbuildings built without permits. When they issue a notice, it is a formal legal warning that your property allegedly violates municipal ordinances — but it is not a final determination of guilt.

Ignoring this notice is the worst thing you can do. Under Colorado Rev. Stat. § 31-15, Denver has the authority to:

• Assess fines of $50–$1000 per day.
• Place a lien on your property once fines exceed $1,000, preventing you from selling or refinancing.
• Hire private contractors to abate the violation and bill you for the cost plus a 25–100% administrative surcharge.
• In severe cases, initiate misdemeanor criminal proceedings under CO law.

The Most Common Inspector Errors on This Violation Type

Our analysis of Unpermitted Structure cases across CO shows that inspectors make procedural errors in a significant percentage of notices. These errors are your leverage:

• structure predates permit requirement
• structure within exempt size threshold
• permit was issued but not closed

Your Strongest Defense Angle

Many structures were built before permit requirements existed, or fall below the square footage threshold that triggers permit requirements. Pre-existing structures often have grandfather protection.

This is the argument that wins the most Unpermitted Structure appeals in CO. But the specific ordinance language in Denver matters — the exact code section, the measurement standard, and the notice requirements all affect whether this argument applies to your case.

Your Rights as a Property Owner in Denver

Receiving a notice does not mean you are automatically liable. Under Colorado Rev. Stat. § 31-15, you have specific due process rights that Denver code enforcement must respect:

• Right to Proper Notice: The citation must clearly state the exact ordinance section violated, the specific condition that constitutes the violation, and what corrective action is required.
• Right to Appeal: You have 10 days to contest the violation before a hearing officer or magistrate. This deadline is absolute — missing it waives your appeal rights.
• Right to a Hearing: You are entitled to present evidence, call witnesses, and cross-examine the inspector at your appeal hearing.
• Right to Reasonable Compliance Time: You must be given adequate time to comply before fines are assessed. Unreasonably short compliance windows are grounds for appeal.

Once fines exceed $1,000, Denver may record a lien against your property — a serious consequence that affects your credit and your ability to sell or refinance.
