With its panoramic views of the Cascade Mountains and proximity to the Deschutes River, Bend, Oregon has become a sought-after place for homeowners wanting to expand their property with a tiny home, prefab ADU, or backyard guest house.
The process of adding a modular accessory dwelling unit in Bend can feel intimidating. Every jurisdiction has unique requirements for permitting, site preparation, and delivery, and what seems straightforward at first can quickly become complex. Understanding the local landscape and building codes is key to a smooth project.
Fortunately, we’re here to help. Check out our guide below on how to make adding a tiny home or modular ADU to your property easy.Determining if a tiny home is right for you begins with your goals. Many Bend homeowners look to add a modular ADU to create space for family, downsize while staying close to nature, or generate rental income in the city’s strong vacation and long-term rental market. Others may be purchasing new property and want to plan a small secondary dwelling from the start.
Adding a tiny home makes sense in several situations:
You own a property and want to add extra living space
You’re helping a parent or adult child live nearby
You want to create an income-producing rental in Bend’s competitive market
You’re seeking a downsized lifestyle while keeping flexibility and comfort
The first step in permitting a tiny home in Bend is identifying the proper authority. Depending on where the property sits, you may need to apply with the City of Bend or with Deschutes County. Both provide zoning and building code information on their websites to guide property owners.
Once you know which jurisdiction applies, the next step is determining what structures are allowed. In most cases, additional dwellings fall under accessory dwelling units, sometimes referred to as guest houses or secondary dwelling units. ADUs can be detached or attached, and requirements vary depending on lot size, zoning, and intended use.
Working with a permitting specialist early in the process helps avoid delays and ensures compliance with local codes, saving both time and money.
Research Your Jurisdiction
Determine if your property falls under the City of Bend or Deschutes County. Review zoning maps and building code guidelines provided online.
City of Bend: Planning Division
Deschutes County: Community Development
Confirm What’s Allowed
Identify whether your project qualifies as an accessory dwelling unit, guest house, or another category. Requirements differ depending on whether it’s a primary or secondary dwelling.
Prepare Documentation
Gather site plans, property information, and any required engineering documents.
Submit Your Application
File permits with the correct jurisdiction, along with associated fees.
Coordinate Reviews and Approvals
Expect plan checks, possible site visits, and reviews to ensure compliance with zoning, building, and safety codes.
Receive Final Permits
Once approved, you can proceed with site preparation and delivery of your modular ADU.
Choosing the right builder requires careful research and a clear understanding of your project. Look for experience in designing and constructing homes that align with your preferred size, style, and complexity.
An established builder will have a portfolio of past projects, along with client reviews and testimonials that reflect their reliability and craftsmanship. Speaking with previous customers can give insight into communication, work quality, and whether deadlines were met. Local knowledge is especially important in Bend to ensure all zoning and code requirements are handled correctly.
Transparency is equally critical. The right builder should provide a detailed estimate, outline possible cost changes, and offer clear timelines. Ask about materials, warranties, and aftercare services to ensure long-term quality and peace of mind.
The best partner will combine technical skill with open communication, helping you bring your vision to life within your budget.
A modular builder constructs homes inside a factory setting, where sections of the home are completed under strict quality control. These modules are then transported to your site in Bend and assembled on a permanent foundation.
This process minimizes delays caused by weather and keeps materials protected indoors. It also ensures consistent standards and efficient scheduling, which shortens the overall project timeline. Modular homes are designed to meet or exceed Bend’s building codes, making them a dependable option.
Traditional on-site construction, often called stick-built, happens directly at the property. While this method allows flexibility for last-minute changes, it is often slower due to weather and coordination among trades. Both methods have strengths: modular emphasizes speed and predictability, while on-site provides customization and local adjustments.
Modular home builders offer significant savings when it comes to off-site built ADUs. Here’s an example of how combining the permitting, production and installation of a tiny home adds up:
| Item | Cost |
|---|---|
| Model B (Base price) | $67,500 |
| Upgrades (Optional additions & Appliances) | $12,000 |
| Site work, Foundation, Delivery & Setup | $34,000 |
| Sub Total w/ Tax (WA) | $125,172 |
| Permits (Wolf Service Fee & Jurisdiction Fee) | $7,500 |
| Total | $132 672 |
