Overview of ADU Laws in Aurora

Accessory Dwelling Units (ADUs) in Aurora, Colorado are governed by a specific set of regulations which reflect the city's commitment to offering flexible housing options to residents. The City of Aurora has adapted its zoning code to better accommodate ADUs, recognizing their potential to provide additional income, housing, and versatility for property owners.

ADUs are independent residential units that share the same lot as a primary residence. They can either be attached to the main house, such as a basement unit, or detached, like a backyard cottage. In 2018, notable changes to ADU regulations were made, aiming to streamline the process and encourage the development of these units.

Under the Aurora Unified Development Ordinance, there are certain use-specific standards for ADUs. Here are some key points to consider:

• Zoning: ADUs are permissible in various residential zones subject to compliance with certain conditions.
• Occupancy: Only one family group is usually allowed to reside in an ADU.
• Size: Restrictions may apply to the size and expansion of the unit.
• Location-Specific Regulations: The standards may vary based on the location within the municipality, particularly in areas of special concern like the Accident Potential Zone District.

The Aurora City Council regularly reviews and updates these ordinances to reflect the evolving housing needs of the city. Property owners within Aurora are expected to adhere to these regulations to ensure their ADU projects align with the municipal requirements. For more detailed information, one can review the dedicated sections of the Aurora Unified Development Ordinance tailored to residential and accessory uses.

Zoning Requirements for ADUs in Aurora

Aurora's zoning requirements for Accessory Dwelling Units (ADUs) are explicit, affecting the permissible locations, lot specifications, and placement within a property.

Applicable Zoning Districts

In Aurora, ADUs are subject to specific zoning districts regulations. While the Unified Development Ordinance details the exact districts, it is important to note that not all zones permit ADUs. Property owners must verify that their land is within a zone that allows for the construction or addition of an ADU.

Lot Size and Density Regulations

Aurora's zoning regulations have clear guidelines on lot size and density for ADUs. These regulations help preserve the character of neighborhoods while accommodating growth. Owners must adhere to minimum lot sizes, which influence the ability to build ADUs, and density requirements, which determine the number of dwelling units allowed per acre.

Setbacks and Location Restrictions

Setbacks and location play a crucial role in where ADUs can be placed on a property. These restrictions ensure that ADUs do not encroach upon neighboring properties or affect the general appearance of the neighborhood. Specific distances from property lines and the main residence must be maintained, and these measurements are defined within the Building & Zoning Code of the city of Aurora.

ADU Design and Size Standards in Aurora

In Aurora, Accessory Dwelling Units (ADUs) are subject to specific regulations to maintain community aesthetics and functionality. Size and design standards are central to these regulations, ensuring ADUs blend in with existing neighborhoods while providing versatile living spaces.

Maximum Size Limitations

• Detached ADUs cannot exceed 800 square feet or be taller than 20 feet.
• Attached ADUs must be smaller than the main residence and are often limited by lot coverage ratios.

These limits are designed to keep ADUs as secondary to the primary structure, both in function and in form.

Building and Safety Codes in Aurora

When constructing or modifying an Accessory Dwelling Unit (ADU) in Aurora, the City of Aurora's Building Department ensures that building and safety codes are rigorously followed to maintain community standards and safety.

Inspections and Compliance

The Inspection process for ADUs in Aurora is conducted by the Department of Building Safety to assess compliance with various building regulations. To initiate this process, compliance with the 2021 International Residential Code (IRC) is essential, particularly for areas such as the kitchen, bathroom, and bedroom facilities. The department oversees regular inspections during different stages of construction to verify that all aspects of the physical structure align with prescribed safety codes.

During the construction process, inspections are required at various stages to ensure compliance and safety. This includes a plans review during the pre-construction stage, an inspection for footings and foundation in the foundation stage, a review of structural integrity during framing, and a final inspection for overall safety and compliance before sign-off. Each of these checkpoints helps to guarantee that the construction meets necessary standards and regulations.

Health and Safety Requirements

The codes governing health and safety are stringent, with the IRC detailing minimum standards for various room types within an ADU. The kitchen must meet requirements for food preparation safety, and bedrooms must have proper egress windows. To ensure standards are met, the International Building Code (IBC) and its specific regulations are taken into account. Health and safety are paramount, and any deficiencies can lead to non-compliance, necessitating further inspection or adjustment in the construction approach.

Each area of the ADU must adhere to specific health and safety criteria:

• Kitchen: Proper ventilation, electrical and plumbing codes
• Bathroom: Adequate sanitation facilities, non-slip flooring, sufficient ventilation
• Bedroom: Fire safety measures, smoke detectors, escape routes

Adherence to these codes promotes the well-being of residents and supports the commitment of the City of Aurora to maintain a safe and compliant living environment.

Local Impact of ADUs in Aurora

Accessory Dwelling Units (ADUs) have become a notable solution in Aurora to the pressing housing shortage, providing an innovative approach to increasing the housing supply while offering various community advantages.

Effect on Housing Supply

The introduction of ADUs in Aurora, often referred to as mother-in-law apartments, granny flats, or secondary suites, has proven to be a strategic response to the housing crisis. By allowing homeowners to convert garages or basements or construct a separate unit on their property, Aurora is addressing the housing supply issue. In Colorado, cities like Denver and Colorado Springs on the Front Range have also adopted ADU regulations, which have added much-needed inventory to the Denver metro area's constricted housing market. Reports have shown that a majority of newly constructed ADUs are indeed contributing to the diversification of available housing options, hereby easing the housing supply constraints.

Community Benefits and Considerations

ADUs offer several community benefits that extend beyond expanding housing choices. They provide homeowners with the opportunity for additional rental income, which can help with mortgage payments and property upkeep, creating a positive economic ripple effect. In addition, ADUs can serve as viable living spaces for family members, such as offering a separate but proximate housing solution for aging relatives, which can strengthen family support systems. However, there remain important considerations for communities. The increase in density can strain local infrastructure, and there is an ongoing need to balance neighborhood character with new development. Despite these challenges, ADUs stand as a largely popular and pragmatic housing solution when executed with careful planning and stakeholder cooperation.

Published studies and local ordinances underscore the necessity to monitor ADU development closely, ensuring that they continue to provide benefits without overwhelming existing community resources or altering the neighborhood dynamics significantly.
