Tualatin's Home Business: The Rules That Matter

Every city handles home business a little differently. In Tualatin, Oregon, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Signage Rules

A residence housing a home occupation may have only one sign. Sign structures require a building permit application through the Planning Department. Sign permit applications are available through the city's forms portal.

Key details: Signs Allowed: 1 per residence. Permit: Building permit for sign structures. Application: Planning Department. Contact: 503-691-3026.

Sign removal order. Permit revocation risk. Code compliance fines $100 to $500.

Zoning Restrictions

Home occupations in Tualatin are allowed in residential zones as a conditional accessory use of a dwelling under Tualatin Development Code (TDC) Chapter 34 (Special Regulations), with additional standards drawn from the city's published Home Occupation Standards. The operator must hold a current City of Tualatin Business License, must own or operate the home occupation as a resident at the site, may employ only one on-site non-resident employee (off-site employees are unlimited), must store all materials and equipment inside built structures on the premises, and may not generate noise, smoke, or odors exceeding normal residential use. One sign is permitted. Customer trips between 10:00 p.m. and 7:30 a.m. are restricted.

Key details: Governing Chapter: TDC Chapter 34 (Special Regulations) - Home Occupations at TDC 34.031-34.055. Code Interpretation Pathway: TDC 31.070. Allowed Zones: Residential zones (e.g., RL Zone under TDC Chapter 40). Operator Requirement: Must be a resident at the home occupation site. On-Site Employees: One non-resident maximum; off-site employees unlimited.

Operating a home occupation in Tualatin without a current City of Tualatin Business License is a violation independently of TDC Chapter 34. Operating in a manner that exceeds the TDC 34 home-occupation standards (multiple on-site non-resident employees, outdoor storage, retailing not ancillary to the home occupation, signs in excess of the one permitted, customer trips outside the 7:30 a.m. - 10:00 p.m. window, or noise/smoke/odor exceeding normal residential use) converts the use into a commercial use that is not allowed in the residential zone; Tualatin Planning Division and Code Enforcement can issue zoning-violation notices, escalating civil penalties under the general code-enforcement framework, and can ultimately seek abatement or an injunction requiring the use to cease. Where the home occupation also generates noise that triggers TMC Chapter 6-14, the noise ordinance applies in parallel. Operators uncertain whether a contemplated activity qualifies should request a code interpretation under TDC 31.070 from the Tualatin Planning Division before commencing the use.

Customer Traffic Restrictions

No employee, client, subcontractor, or delivery trips may be made between 10:00 PM and 7:30 AM. Working on 3 or more motor vehicles per week creates a presumption of unauthorized home occupation. All materials must be stored inside structures.

Key details: No Trips: 10:00 PM – 7:30 AM. Vehicle Work: Under 3/week to avoid presumption. Storage: Inside structures only. Planning Contact: 503-691-3026.

Excessive traffic complaints: permit review. Revocation for repeat violations. Cease-and-desist order.

The Bottom Line

Tualatin's home business rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Tualatin is broadly strict or permissive.

Keep in mind that Tualatin can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
