City of Naperville Building Design Guidelines
The City of Naperville's Building Design Guidelines serve as a comprehensive framework for maintaining architectural character and development quality within the community. These guidelines ensure that new construction, additions, and renovations respect Naperville's aesthetic values while promoting functional, sustainable, and accessible buildings.
As one of Illinois' most vibrant communities, Naperville places high value on thoughtful development that enhances the city's identity while meeting resident and business needs. These guidelines provide direction for property owners, developers, architects, and contractors planning building projects throughout the city.
Historical Context and Community Values
Naperville's architectural heritage reflects its Midwest roots and evolution from a small settlement to a thriving suburban center. The city values diverse architectural styles, from Victorian and historic downtown buildings to modern residential developments emphasizing smart design principles.
The Building Design Guidelines stem from Naperville's Comprehensive Plan, which emphasizes:
Preservation of Community Character: Maintaining distinctive qualities that make Naperville neighborhoods and commercial areas attractive and livable.
Quality of Place: Ensuring buildings contribute positively to the urban fabric through thoughtful design and attention to detail.
Sustainable Development: Encouraging environmentally responsible building practices that conserve resources and reduce long-term operational costs.
Accessible Design: Promoting universal design principles that create inclusive spaces accessible to people of all abilities.
Residential Design Guidelines
Residential development in Naperville encompasses single-family homes, duplexes, townhomes, and various multi-family housing types. The residential design guidelines focus on creating harmonious neighborhoods while allowing appropriate design expression.
Neighborhood Compatibility
Residential structures should respect the character of existing neighborhoods. This includes consideration of:
| Design Element | Guideline |
|---|---|
| Scale | Buildings should be appropriately sized relative to neighboring properties. |
| Setbacks | Maintain setbacks consistent with established neighborhood patterns. |
| Roof Forms | Roof designs should complement prevalent architectural styles in the vicinity. |
| Materials | Use quality materials consistent with those found in the surrounding area. |
Architectural Character
Design quality enhances property values and community pride. Residential buildings should exhibit intentional design, thoughtful details like well-crafted fenestration and trim, quality materials appropriate to the style, and balanced proportions between building elements for visual harmony.
Commercial and Mixed-Use Design Guidelines
Naperville's commercial areas range from traditional downtown storefronts to shopping centers and office parks. Commercial design guidelines emphasize creating distinctive, pedestrian-oriented places that support economic vitality.
Building Placement and Orientation
Commercial buildings should enhance street character and pedestrian experience through:
Street Frontage: Buildings should address streets with active frontages and engaging facades.
Pedestrian Scale: Design elements near sidewalks should relate to human scale rather than creating overwhelming blank walls.
Transparency: Incorporate windows and entrances along primary facades to create visual interest and connection to interior activities.
Entry Emphasis: Design prominent, clearly visible building entrances that welcome customers and visitors.
Architectural Quality
High-quality commercial architecture contributes to a vibrant, economically successful city. Commercial buildings should exhibit strong design concepts and avoid generic, formulaic appearance.
Key considerations include contextual design that responds to surroundings, facade articulation with variation in massing and materials, use of high-quality durable materials, and integration of signage as part of the architectural design.
Landscape and Site Design Guidelines
Integrating buildings with their surrounding landscape enhances community character, environmental quality, and property values. Site design guidelines address outdoor spaces around buildings.
Stormwater Management
Naperville encourages innovative stormwater management through green infrastructure such as rain gardens, bioswales, and permeable pavement; appropriate retention practices based on site conditions; and measures that filter pollutants from runoff before entering waterways.
Landscape Integration
Landscape design should complement architectural elements and provide functional benefits through use of native plant species appropriate to site conditions, appropriate street tree planting in public rights-of-way, landscaping to screen service areas and utilities, and creation of usable outdoor spaces for residents, employees, or visitors.
Sustainable Design Principles
Naperville encourages sustainable building practices that contribute to environmental quality and long-term value. The city incorporates sustainability considerations throughout the design review process.
Energy Efficiency
Buildings should minimize energy consumption through proper building envelope with appropriate insulation and windows; efficient HVAC systems, lighting, and appliances; and consideration of renewable energy technologies where appropriate.
Resource Conservation
Sustainable buildings use resources efficiently throughout their lifecycle, from construction through operation and eventual renovation or demolition.
Key considerations include selection of long-lasting materials, use of recycled materials when appropriate, implementation of water-saving fixtures and irrigation systems, and design that accommodates recycling and composting strategies.
Design Review Process
Naperville utilizes a design review process to ensure that proposed developments meet community standards and contribute positively to the built environment. The process varies based on project scale, location, and zoning.
Projects Subject to Review
| Project Type | Review Body |
|---|---|
| Downtown development or significant alterations | Downtown Advisory Commission |
| Historic preservation or properties in historic districts | Historic Preservation Commission |
| Planned developments and significant commercial projects | Plan Commission |
| Other projects requiring special approval | Zoning Board of Appeals |
Application Process
Property owners and developers should be prepared to submit comprehensive documentation including detailed site plans showing building placement and landscaping; all building elevations showing architectural details; material samples; documentation showing how proposed design relates to surrounding development; and a written explanation of design concepts and alignment with guidelines.
