Deschutes County Fire Hardening Requirements R327: Protecting Your Bend Home from Wildfire

Understanding the new R327 ordinance, defensible space, and how Newport Avenue Landscaping helps you achieve wildfire resilience.

Navigating Bend's New Wildfire Codes: R327 and Defensible Space

Central Oregon, with its stunning natural beauty, also faces an increasing threat from wildfires. In response, Deschutes County and the City of Sisters have taken proactive steps to enhance community safety through new building codes and upcoming landscaping ordinances. For homeowners in Bend and across Deschutes County, understanding these changes, particularly the R327 fire hardening requirements and the evolving defensible space guidelines, is paramount to protecting their properties and loved ones. Newport Avenue Landscaping is here to guide you through these regulations and provide expert solutions to make your home wildfire-resilient.

The R327 ordinance marks a significant shift in construction standards for new homes, focusing on ignition-resistant materials. For unincorporated Deschutes County and the City of Sisters, it took effect April 1, 2026. The City of Bend adopted its own equivalent home hardening requirements, effective May 15, 2026 for new residential building permits. This is just one piece of the puzzle. The Oregon State Fire Marshal is also drafting a comprehensive defensible space ordinance, anticipated for local adoption in 2026, which will directly impact how we manage our landscapes. This page will delve into the specifics of R327, explain the critical concept of defensible space, highlight the landscaping implications, and demonstrate how Newport Avenue Landscaping's full-service approach can help you not only comply but thrive in a fire-wise environment.

Deschutes County R327: What New Construction Needs to Know

The Deschutes County R327 fire hardening code is now mandatory for all new dwellings and accessory structures within unincorporated Deschutes County and the City of Sisters (effective April 1, 2026) [1]. The City of Bend adopted equivalent home hardening requirements effective May 15, 2026, applying to all new residential building permits submitted on or after that date. This ordinance, part of the Oregon Residential Specialty Code (ORSC) Section R327, is a critical measure designed to reduce the risk of home ignition from embers, radiant heat, and direct flame contact during a wildfire event. It's important to note that R327 focuses on the building's construction itself, not the surrounding landscape, though both are vital for comprehensive wildfire protection.

Who Does R327 Affect?

The R327 provisions are specifically applicable to new construction. This includes:

• All newly constructed dwellings.
• All newly constructed accessory structures (e.g., detached garages, workshops).

It's crucial for homeowners and builders to understand that R327 generally does not apply to existing homes, partial repairs, remodels, or additions. Manufactured dwellings, built to federal HUD standards, are also typically exempt, although many manufacturers offer optional fire hardening or wildfire packages [1]. This distinction is key: if you're building a new home or a significant new structure on your property, R327 compliance is a must.

Key Requirements and Materials

The core purpose of R327 is to make structures more resistant to wildfire. This is achieved through the use of specific ignition-resistant building materials and construction practices. Many of these materials are already common in modern construction, such as double-pane windows, cementitious siding (like Hardie Panel), and Class B or better asphalt shingles for roofing [1]. The Deschutes County Building Safety Division accepts products listed in the CalFire Building Materials Listings & Wildland Urban Interface (WUI) Listed Products Handbook for compliance, simplifying the selection process for builders.

While R327 is a significant step, it's important to remember that it makes a home more resistant, not fireproof. It buys critical time for evacuation and for emergency responders to protect life and property. The next crucial layer of protection comes from the surrounding landscape – defensible space.

Beyond the Walls: The Impending Defensible Space Ordinance

While R327 addresses the 'hardening' of structures, the Oregon State Fire Marshal is actively developing a statewide defensible space ordinance, expected to be adopted locally in 2026 [2]. This ordinance will establish minimum requirements for reducing wildfire risk on lands, creating a crucial buffer between your home and potential wildfire threats. Defensible space is not just about clearing vegetation; it's a strategic approach to landscape management that significantly increases your property's chances of surviving a wildfire and provides firefighters with a safer environment to work.

Understanding Defensible Space Zones

The concept of defensible space is typically broken down into three distinct zones, each with specific guidelines for vegetation management [3]:

• Zone 0 (0-5 feet from the home): The Immediate Zone. This area, closest to your home, should be a non-combustible zone. This means removing all flammable vegetation, especially directly under eaves and around windows. Keep roofs and gutters free of leaves and debris. Consider non-combustible materials for patios and walkways.
• Zone 1 (5-30 feet from the home): The Intermediate Zone. In this zone, the goal is to create a lean, clean, and green landscape. Use low-flammability plants, ensure trees are well-spaced, and prevent canopies from touching. Remove dead or dry vegetation. Woodpiles should be at least 30 feet from any structure, and combustible materials like propane tanks should be at least 10 feet away.
• Zone 2 (30-100+ feet from the home): The Extended Zone. This outermost zone focuses on reducing the intensity of a wildfire as it approaches your property. Selectively prune and thin trees and shrubs, removing highly flammable vegetation. Maintain proper spacing between trees and ensure branches are at least 10 feet from powerlines and buildings. For taller trees (over 18 feet), prune branches up to 6 feet from the ground; for shorter trees, prune up to one-third of their height.

These zones are designed to work together, creating layers of protection that disrupt the path of a wildfire and reduce its impact on your home. Implementing these practices proactively is key to safeguarding your property and contributing to a more fire-resilient community.

Landscaping for Resilience: Plant Choices in a Fire-Prone Region

The upcoming defensible space ordinance will undoubtedly place a greater emphasis on fire-wise landscaping practices. For homeowners in Bend and Central Oregon, this means making informed choices about the plants they cultivate and how they maintain their outdoor spaces. The right landscaping can act as a natural firebreak, while poor choices can inadvertently fuel a wildfire.

High-Risk Plants to Avoid

Certain plants common in Central Oregon are highly flammable due to their volatile oils, fine dead material, or dense growth habits. These should be avoided or significantly reduced, especially within the immediate and intermediate defensible space zones. High-risk plants include:

• Juniper: Considered one of the most dangerous due to its highly volatile oils and dense, dry foliage.
• Manzanita: Another common shrub with flammable characteristics.
• Arborvitae, Cedar, Pine, Spruce: Many conifers contain flammable resins and can ignite easily, especially when dry.

The tragic Flat Fire in 2025, which consumed over 20,000 acres and destroyed four homes near Sisters, serves as a stark reminder of the devastating impact wildfires can have, underscoring the urgency of fire-wise landscaping [4].

Fire-Resistant Plants to Embrace

Conversely, many beautiful and drought-tolerant plants thrive in Central Oregon while offering increased fire resistance. These plants typically have high moisture content, lack volatile oils, and grow in a less dense manner. Consider incorporating these into your landscape:

• Yarrow: A hardy perennial with attractive flowers.
• Stonecrop/Sedum: Succulents that store water, making them naturally fire-resistant.
• Snowberry: A native shrub with good moisture content.
• Currant: Another native shrub that can be a good choice.
• Aspen and Maple: Deciduous trees that are generally more fire-resistant than conifers.
• Native Grasses: Many native grasses remain green longer and have less fine, dry fuel than invasive species.

By strategically choosing fire-resistant plants and maintaining them properly, you can create a beautiful and safe landscape that enhances your home's protection against wildfires.
