Sidewalk & Pedestrian Rules in Boulder, CO

Boulder maintains 143 local ordinances across all categories, and 3 of those deal specifically with sidewalk & pedestrian rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Boulder falls on the strict-to-permissive spectrum compared to other cities.

Sidewalk Repair

Boulder places the duty to keep abutting sidewalks in good repair on the adjacent property owner, not the city. Under Section 8-2-6, B.R.C. 1981, if the city manager finds a sidewalk substandard, the owner gets 30 days to start and 60 days to finish repairs, with the city sharing half the cost, or the city can do the work and bill the owner.

Key details: Duty holder: Adjacent property owner. Time to start repair: 30 days from notice. Time to finish repair: 60 days from notice. City cost share: 50 percent of city's cost. Admin surcharge if city does it: Up to 15 percent.

Failing to maintain a sidewalk in good repair, or ignoring a city manager's repair notice under Section 8-2-6, lets the city perform the work itself and bill the property owner the full cost plus up to 15 percent for administration. Unpaid charges are certified to the Boulder County Treasurer and collected the same way as delinquent property taxes under Section 2-2-12, B.R.C. 1981.

Obstruction Rules

Boulder bars anyone from placing a building, fence, landscaping, or other obstruction in a public right-of-way, path, alley, or public easement without first getting city permission. Section 8-6-3, B.R.C. 1981, works with a broad definition of obstruction, from fences too close to a sidewalk to plants that block the view of traffic, and treats an unpermitted one as a public nuisance.

Key details: Permit required: Before any right-of-way obstruction. Fence/hedge setback: 18 inches from sidewalk. Admin surcharge if city removes: Up to 15 percent. Legal treatment: Public nuisance, suable by any resident. Governing sections: B.R.C. 1981 §§ 8-6-2 to 8-6-4.

Placing or maintaining an unpermitted obstruction in a public right-of-way, path, or easement violates Section 8-6-3, B.R.C. 1981, and is treated as a public nuisance under Section 8-6-4 that the city or any resident can sue to abate. If an owner ignores a removal order, the city manager can remove the obstruction directly and bill the owner the cost plus up to 15 percent for administration.

Compared to other cities, Boulder takes a harder line on obstruction rules. The enforcement and penalty structure reflects that.

Encroachment Permits

No one may build, place, or maintain a structure, fence, landscaping, or other encroachment in a Boulder public right-of-way or public easement without city permission under Boulder Revised Code section 8-6-3. The city manager grants revocable permits of up to three years under section 8-6-6, and commercial sidewalk encroachments must leave at least eight feet of clearance.

Key details: Base rule: Permit required for any right-of-way encroachment. Permit length: Revocable permit up to three years. Sidewalk clearance: Minimum 8 feet vertical/horizontal in commercial areas. Reviewing departments: Planning, public works, fire, and police. Unpermitted encroachment status: Treated as a public nuisance.

An encroachment placed or kept in the right-of-way without a permit is a public nuisance under section 8-6-4 that the city or any resident can sue to remove. The city manager can order it removed on a reasonable timeline, and if the owner doesn't comply, the city can remove it and charge the removal cost plus up to 15 percent for administration, certifiable as a lien through the Boulder County Treasurer. A hearing under Chapter 1-3 is available to contest the order.

Compared to other cities, Boulder takes a harder line on encroachment permits. The enforcement and penalty structure reflects that.

If you are a homeowner, renter, or business owner in Boulder, take the time to understand these requirements before they become a problem.
