Understanding Zoning in Portland

Zoning in Portland, OR, is designed to manage land use and development. This includes the rules set by the city to control how properties can be used, what types of buildings are allowed, and how new developments must proceed. Below, readers will find specific details about Portland’s zoning code and processes.

Overview of Portland Zoning Code

Portland's zoning code, detailed in Title 33, was developed to align with city, regional, and state regulations. The Bureau of Development Services (BDS) administers these rules, ensuring that new developments comply with the city’s strategic plans. Zoning codes dictate land use, building dimensions, and neighborhood compatibility. This includes regulations about height limits, setbacks, and lot coverage. Historic zoning and land division codes are also part of this comprehensive zoning framework.

Introduction to Residential Zoning

Residential zoning in Portland is critical for maintaining neighborhood character and managing growth. There are different zones such as R5, R10, and RX, each with unique criteria. For example, R5 includes single-family homes on lots of about 5,000 square feet while RX allows dense residential development like apartments. Understanding the specific zone for a property helps determine permissible uses, building heights, and other requirements. Property owners can find out their specific zoning requirements by contacting General Inquiries at (503) 823-7300.

Building Permit Application Process

Before starting any construction, homeowners and developers must apply for building permits. The process starts with understanding the zoning requirements for the project. Individuals need to submit plans that comply with regulations, including site plans, building designs, and environmental considerations. The permit application process often involves multiple steps, including plan reviews and inspections by BDS. Applicants can call (503) 823-7300 for assistance. The front desk team is available Monday through Friday from 8 a.m. to 5 p.m.

Shelter to Housing Continuum Project

The Shelter to Housing Continuum Project aims to expand housing options in Portland. Approved by the City Council, this initiative allows more flexibility in how properties can be used, especially for shelter and housing. It includes amendments to the zoning code to support temporary shelters, group living situations, and affordable housing projects. This project, part of the broader Design Overlay Zone Amendments, is crucial for addressing homelessness and housing shortages.

Comprehensive Plan and Zoning Reform

Portland's Comprehensive Plan outlines the city’s goals for land use and urban development. This plan guides the zoning code updates and reforms to ensure they align with long-term goals. Recent updates aim to promote sustainable growth, enhance urban livability, and support affordable housing initiatives. The Comprehensive Plan includes policies that address transportation, economic development, and environmental protection. Understanding this plan is essential for developers and property owners to navigate zoning reforms effectively.

By following these detailed guidelines and processes, residents and developers in Portland can ensure their projects align with city regulations and contribute to the community's growth and development.

Residential Infill Project (RIP) and Its Impact in Portland

The Residential Infill Project (RIP) in Portland, OR, aims to increase housing options and affordability by updating zoning laws. It includes regulations on building size, allowances for middle housing, and incentives for greater affordability.

Goals of Residential Infill Project

The main goal of the Residential Infill Project is to increase the availability of diverse housing types. By allowing the construction of duplexes, triplexes, and fourplexes on lots previously zoned for single-family homes, the project aims to address housing shortages.

Additionally, RIP seeks to make housing more accessible and affordable for low- and moderate-income residents. The project promotes efficient land use and seeks to create walkable, sustainable neighborhoods.

Infill and Housing Density

Infill refers to developing vacant or underused parcels within existing urban areas. The RIP increases housing density in Portland’s single-dwelling zones (R2.5, R5, and R7) by permitting up to four units on a single lot. This change helps to maximize the efficient use of land and existing infrastructure.

Increasing housing density aims to meet the growing demand for urban living while preserving green spaces outside the city. These measures help build vibrant communities with access to amenities and services.

Regulations for Duplexes, Triplexes, and Fourplexes

Under the Residential Infill Project, regulations for new duplexes, triplexes, and fourplexes include limits on building scale and design standards to ensure compatibility with existing neighborhoods.

Duplexes and triplexes must meet specific height and yard requirements, while fourplexes have more stringent guidelines to manage their larger footprint. These regulations aim to minimize adverse effects on neighborhood character while increasing housing options.

Affordability and Deeper Affordability in RIP

RIP includes measures to enhance housing affordability through a "deeper affordability" bonus. Projects that provide units affordable to households earning 60% or less of the median family income can access greater allowances in terms of unit numbers and building size. This approach encourages the development of low-income housing.

Deeper affordability incentives also include reduced parking requirements for projects meeting affordability thresholds. By lowering development costs, RIP aims to make affordable housing projects more financially viable for developers.

In summary, the Residential Infill Project impacts housing in Portland by promoting diverse and affordable housing options through updated zoning regulations.

Housing Diversity and Availability in Portland

Portland has implemented several reforms to increase housing diversity and availability. These changes address different housing types, expand options in low-density zones, support Accessory Dwelling Units (ADUs) and cottages, and encourage nonprofit involvement in housing development.

Expanding Housing Types

Portland's new zoning laws allow for more housing types in residential areas. The Residential Infill Project (RIP) introduces flexibility, enabling the construction of duplexes, triplexes, and fourplexes in zones previously restricted to single-family homes. This change aims to increase the availability of affordable housing. By offering diverse housing options, the city can cater to different income levels and family sizes, promoting a more inclusive community.

Middle Housing and Low-Density Zones

Middle housing refers to multi-unit housing types such as duplexes, triplexes, and quadplexes, often found in low-density zones. Portland’s zoning reform has expanded these options, allowing for increased density without drastically changing neighborhood character. Middle housing can bridge the gap between single-family homes and large apartment complexes, offering more affordable and versatile living options. This approach promotes economic inclusion by accommodating a broader range of income levels and household types.

Accessory Dwelling Units and Cottages

Accessory Dwelling Units (ADUs) and cottages provide additional housing without requiring significant land development. ADUs are small, self-contained living units on the same lot as a primary residence. Cottages are similar but may be grouped together in a cottage development. Portland has embraced these housing options to increase urban density and provide more affordable living spaces. These units can serve as housing for extended family, rental income for homeowners, or affordable options for small households.

Nonprofits and Habitat for Humanity Involvement

Nonprofits like Habitat for Humanity play a crucial role in Portland’s housing landscape. These organizations help build and maintain affordable housing, ensuring that lower-income residents have access to quality homes. Habitat for Humanity and other nonprofits have been integral in the city's efforts to provide diverse and affordable housing options. They collaborate with the city to leverage funds, volunteer efforts, and community partnerships to construct homes for those in need, furthering Portland's affordable-housing policy.

Expanding housing types, promoting middle housing, supporting ADUs and cottages, and involving nonprofits contribute significantly to Portland's efforts in enhancing housing diversity and availability. These measures aim to create a more inclusive and economically diverse community.

Residential Development Standards in Portland

Portland, OR, has specific residential development standards that residents must follow. These standards cover important aspects such as lot size, building height, privacy considerations, setbacks, driveways, and overlay zones.

Lot Size and Residential Lot Development

In Portland, the size of a residential lot varies depending on the zone. For example, in an R5 zone, each lot must be at least 5,000 square feet. Lot size impacts the number of units allowed on the property and the type of developments possible.

Residential lot development also has regulations on partitions and land divisions. Subdividing a larger lot into smaller parcels needs approval from the city's planning department. The aim is to ensure that new developments fit well within the existing neighborhood and infrastructure.

Building Height and Privacy Considerations

Building height in residential zones is another crucial standard. Most residential buildings in Portland must not exceed 30 to 35 feet, depending on the specific zoning category. Height limits are set to ensure that new buildings do not overshadow existing homes and to maintain neighborhood character.

Privacy is respected through height restrictions. Tall buildings can impact the privacy of adjacent properties. As a result, height limits, along with design guidelines, help mitigate issues related to overlooking and shadowing.

Setbacks, Driveways, and Livable Space

Setbacks are the required distances between a building and the property lines. In Portland, setback requirements can vary by zone. For instance, front yard setbacks might range from 10 to 15 feet and side yard setbacks from 5 to 10 feet. These regulations ensure adequate spacing between structures for safety, privacy, and aesthetics.

Driveway regulations restrict their width and placement to maintain a continuous streetscape. Ensuring driveways are appropriately designed helps maximize usable outdoor space and comply with livable space requirements.

Overlay Zones and Zoning Code Variations

Overlay zones add another layer of regulation beyond the base zoning. These zones address specific concerns like environmental protection, historic preservation, or design standards. For example, the Environmental Conservation overlay zone has extra rules to protect natural resources.

Portland's Zoning Code also allows for some variations. Developers might use planned development options for more flexible design, provided they meet overall community goals. Compliance with overlay zones ensures balanced development that respects area-specific needs and priorities.
