ADU Contractors in Tigard, Oregon: Building in a Growing Portland Metro Community

Tigard, Oregon is one of the fastest-growing cities in the Portland metropolitan area, with a strong emphasis on increasing housing density and affordability. As part of Washington County and closely tied to regional housing initiatives, Tigard has embraced Accessory Dwelling Units (ADUs) as a practical solution to its housing needs. Whether you're near downtown Tigard, the Metzger neighborhood, or along the Fanno Creek Trail corridor, hiring experienced ADU contractors in Tigard, OR is the first step toward maximizing your property's potential.

Tigard ADU Regulations and Zoning Requirements

Before breaking ground, it's essential to understand Tigard's specific ADU rules. The City of Tigard follows Oregon's statewide ADU legislation, which has significantly loosened restrictions in recent years. Under Oregon House Bill 2001, single-family zones must allow at least one ADU per lot. Tigard's Community Development Code further outlines local standards that your ADU contractor must navigate, including:

  • Maximum ADU size: Typically up to 75% of the primary dwelling's square footage or 800 square feet, whichever is less, though this can vary by zone
  • Setback requirements: Rear and side yard setbacks generally apply, often requiring a minimum of 5 feet
  • Height restrictions: Detached ADUs are generally limited to a maximum height of 25 feet
  • Owner-occupancy: Oregon state law has removed mandatory owner-occupancy requirements for ADUs
  • Utility connections: Separate utility connections may be required depending on the ADU type

Types of ADUs Commonly Built in Tigard

Skilled ADU contractors in Tigard are experienced in building several types of accessory dwelling units suited to the city's residential landscape. The most common types include:

  1. Detached ADUs (DADUs): Standalone structures in the backyard, popular in Tigard's larger residential lots
  2. Attached ADUs: Units connected to the primary home, often used as in-law suites
  3. Garage Conversions: Converting existing garages into livable ADU spaces, a cost-effective option
  4. Basement Conversions: Transforming existing basement space into a fully permitted ADU

Why Hire a Local Tigard ADU Contractor?

Working with a local ADU contractor familiar with Tigard's permitting process through the City of Tigard's Community Development Department can save you significant time and money.
