Items intended for outdoor use on a residential property such as picnic tables, children's toys and bicycles are allowed to be kept outdoors. Items intended for indoor use such as upholstered furniture and household appliances may not be stored outside. Tools, equipment and supplies utilized for automobile repair or construction may not be stored outside.
|Parking on unpaved surfaces
Parking on dirt areas is not allowed. Allowable parking surfaces for single-family dwellings include 6 inches of gravel, road base material (recycled asphalt), asphalt, or concrete. Allowable parking surfaces for 2-unit dwellings or multi-unit dwellings include road base, asphalt, or concrete.
|Too many cars
Denver households are allowed one vehicle per licensed driver, plus one extra vehicle. For example, a household consisting of three licensed drivers may have up to four vehicles at the residence. Additional cars would be considered in violation of the code.
Lawns may not exceed 6” in height. Plant growth may not extend onto adjacent sidewalks, streets or alleys.
Fences must be maintained, built to proper height (generally 4’ in the front and 6’ in the sides and back of residential lots), and constructed with approved materials (no barbed wire, corrugated metal or salvage materials). Check to see whether your fence requires a permit.
For public safety and safe access, snow, landscaping, debris and other obstructions must be removed from public sidewalks. Once snow has stopped falling, residences have twenty-four (24) hours to remove snow and ice from public sidewalks adjacent to their property. Once snow has stopped falling, businesses have four (4) hours to remove snow and ice from public sidewalks adjacent to their property.
Parking or storing inoperable motor vehicles in any residential zone district is restricted to one vehicle that must be stored inside an enclosed garage. A vehicle that is not operable cannot be stored on the street or in a driveway of a home.
Residents may have one yard sale every six months in Denver, provided that the sale lasts for less than 72 hours, items offered for sale were not bought for resale or received on consignment for the purpose of resale, and all external evidence of the sale is removed immediately afterward.
|Home occupations (at-home businesses)
Home occupations are allowed in Denver. The business must be operated by the resident in a completely enclosed structure, the primary dwelling unit or a detached accessory structure as allowed by the zoning code. The home occupation shall not display or create outside the building any external evidence of its operation. A sign of up to 100 square inches in size is allowed. See the Project Guide for Home Businesses for information.
|Too many animals
The Denver Zoning Code regulates how many household pets can be part of a home residence. Violations occur when the number of household pets exceeds 3 dogs, 5 cats, 2 rabbits, or 25 pigeons, or 5 total dogs and cats or 2 domestic honey bee hives.
|Construction without a permit
Most construction projects require a zoning permit and may also require a building permit. For example, construction of fences, sheds, and gazebos all require zoning permits and depending on their design require a building permit too. Check the requirements for your project under Home Projects.
|Too many unrelated people
Any number of persons related by blood, marriage or adoption may live together in a dwelling. In a single-unit dwelling, two unrelated persons per household are allowed, and with a home occupation permit, an additional unrelated person is allowed. In a two-unit dwelling or multi-unit dwelling, four unrelated persons per household are allowed, and with a home occupation permit, two additional unrelated persons are allowed.
The display, location and size of signs placed on private property are regulated by Zoning and other departments and agencies within the City and County of Denver. Read more about permit requirements and approvals of signs to avoid code violations.
