Assessing whether a tiny home is the right choice for you

Determining whether a tiny home is the right fit depends on your specific goals and lifestyle. For homeowners with existing property, adding a modular tiny home can be a smart way to expand your living space without the disruption of traditional construction. Whether you’re creating a private guest house, a retreat for family, or an income-generating rental, tiny homes offer flexibility and affordability. For those purchasing new property, a tiny home provides a quicker, more affordable path to homeownership while allowing for customization to fit your needs.

Tiny homes are also a great solution for multigenerational living, offering independence for a relative while keeping family members close. Additionally, they present a valuable opportunity for those looking to generate residual income with a rental property. To help you evaluate whether a tiny home is the right choice for you, consider the following:

  • Do you need extra living space on your property without major construction?
  • Are you looking for an affordable, efficient housing solution?
  • Is earning rental income through a secondary unit appealing to you?
  • Do you want to provide a private, independent living space for a family member?
  • Are you interested in adopting a more minimalist and sustainable lifestyle?

What is the permitting process like for homeowners in Tigard, Oregon?

The permit process typically starts by identifying the correct governing authority for your location. Depending on your property, you may need to submit permits to the city or the overseeing jurisdiction, which is often the county. Most local authorities provide zoning and building code details on their websites.

Once you’ve identified the appropriate jurisdiction, the next step is to determine which types of structures are permitted. This varies depending on whether the building will serve as the main residence or an additional unit. Secondary homes are often classified as accessory dwelling units (ADUs), guest houses, secondary dwellings, or hardship accommodations. ADUs can either be attached to the main structure or completely separate.

Consulting with a tiny home permit expert or building planner early in the process can save both time and money, significantly simplifying the process of obtaining the necessary permits.

Getting the paperwork started

Start by reviewing the zoning rules for your property through the City of Tigard and Washington County websites or by contacting local planning offices. Make sure your location allows for a tiny home or modular accessory dwelling unit (ADU).

Review Building Codes

Understand the building codes specific to Tigard and Washington County. These codes will govern the construction, safety standards, and structural integrity of your tiny home or ADU.

Consult with City and County Officials

Reach out to the City of Tigard and Washington County planning and building departments. Schedule a consultation to discuss your project and gather details on the specific permit requirements you’ll need to follow.

Prepare Utility Plans

Plan for utility connections (water, sewer, electricity) that align with city and county requirements. Ensure you have a clear plan for site preparation, including grading and foundation placement.

Submit Permit Applications

File the necessary building permit applications with the City of Tigard and Washington County. These submissions may include site plans, utility connection plans, and detailed project information.

Complete Safety Inspections

As construction moves forward, schedule safety inspections with local authorities. These inspections will confirm that your project meets all structural, electrical, and plumbing safety standards.

Obtain Final Approval

After passing all required inspections, finalize the permit process by obtaining a certificate of occupancy or equivalent approval from the city or county, allowing you to legally use your tiny home or ADU.

Choosing the perfect tiny home builder

Choosing the right home builder requires careful research and a clear understanding of your project’s requirements. Start by assessing the builder’s experience, especially in constructing homes that match the size, design, and complexity of the one you have in mind.

An experienced builder will have a portfolio of past projects that showcase their expertise and craftsmanship. Reading reviews, client testimonials, and speaking directly with previous clients can provide valuable insight into the builder’s reliability, quality of work, and ability to meet deadlines. Make sure the builder is well-versed in local building codes and regulations, as this is essential for a smooth permitting process and successful project completion.

In addition to technical expertise, consider how well the builder communicates and their transparency regarding costs and timelines. A trustworthy builder will offer a detailed estimate and be upfront about potential cost increases or delays. Ask about the types of materials they use and whether they provide warranties or post-construction support. These aspects are key to ensuring your home is built with high-quality, durable materials and that you have continued assistance after the project is completed.

Ultimately, the ideal home builder should combine experience, transparency, and effective communication to bring your vision to life within your budget and timeframe.

Modular versus on-site home builders

A modular home builder creates houses in a factory environment, where different sections, or modules, of the home are pre-assembled in a controlled setting. These modules are then transported to the construction site and put together on a foundation.

Modular building offers quicker completion times, as the process isn’t affected by weather or site conditions, and materials are kept indoors, preventing exposure to the elements. The factory setting also ensures stricter quality control and consistent building standards. Modular homes are designed to meet or exceed local building codes, making them a dependable and cost-efficient choice for those seeking a faster and more streamlined construction process.

In contrast, an on-site home builder constructs homes directly at the location where they will be situated. This traditional method, often called stick-built construction, provides more flexibility during the build, allowing for changes and adjustments as the project progresses. However, on-site construction is more prone to weather-related delays and requires careful coordination of various trades, such as framers, plumbers, and electricians, which can extend the timeline.

While on-site construction may take longer and involve more complexity, it offers greater customization and benefits from local expertise, making it ideal for projects requiring unique designs or adjustments to specific environmental conditions. Both approaches have their advantages: modular builders focus on speed and efficiency, while on-site builders emphasize flexibility and hands-on management.
