Ground-level residences and upper-floor apartments give the Cartwright Apartments a neighborhood-friendly character. Roth views buildings like these as integral parts of a community, influenced by their interaction with the surrounding street environment.
The Cartwright Apartments stand out as a prominent feature on a corner lot during twilight. Its vertical design and ground-floor retail reflect the density-oriented approach Roth anticipates will become more prevalent under Oregon’s updated zoning regulations.

This undertaking embodies the kind of work I established Roth Arc to pursue. It’s a local property that holds the capacity to increase housing availability and address a distinct community need.”— Daniel Roth, AIA, Founder and Licensed Architect, RothArcSALEM, OR, UNITED STATES, August 3, 2026 /EINPresswire.com/ — Licensed Architect Daniel Roth, AIA, has launched Rotharc, a newly formed Salem architecture practice dedicated to multifamily housing, residential design, middle housing, and community and civic structures across the Willamette Valley.
The practice kicks off operations with a residential initiative for a local nonprofit organization in the Salem vicinity. The organization is currently assessing a residential property situated within a multifamily zone. Rotharc is collaborating with the group to determine how the land could accommodate roughly three to five extra units while expanding its housing capacity. This project remains in early planning stages, and the exact number and arrangement of homes have yet to be finalized.
“This project represents the type of work I started Rotharc to pursue,” Roth said. “It is a local property with the potential to provide more housing and serve a clear community need.”
This initiative underscores Rotharc’s overarching emphasis on locally grounded housing and community enhancement. The firm partners with private landowners, local developers, nonprofit entities, and families seeking architectural expertise for residential and community endeavors. Rotharc is not confined to nonprofit or income-restricted housing; it also collaborates with market-rate housing developers and private property owners aiming to add homes, repurpose underutilized land, or gain a clearer insight into a property’s development potential.
“There is a place for nonprofit housing, privately financed housing and locally driven development,” Roth said. “Each model can contribute to the housing supply when the project is planned carefully and responds to the site and the people who will use it.”
Multifamily housing constitutes a core focus of Rotharc’s portfolio. The firm offers architectural services for apartment complexes, small to medium-sized multifamily developments, residential infill projects, and middle housing types such as duplexes, triplexes, fourplexes, townhomes, and cottage clusters. Oregon’s revised housing and zoning regulations have unlocked fresh opportunities for middle housing and residential infill in numerous communities. However, the development potential of any given property continues to depend on local zoning, site conditions, access, utilities, building codes, and permitting requirements.
Before clients commit to a full architectural design or construction plan, Rotharc helps them evaluate these factors. The practice provides site feasibility studies, zoning analysis, land-use assessments, preliminary planning, and code reviews to help property owners understand what might be achievable on a parcel. “Many owners begin with a property and a general idea, but they do not yet know what the site can support,” Roth said. “Early planning gives them clearer information before they make larger decisions about design, financing and construction.”
Alongside multifamily and middle housing, Rotharc delivers custom residential architecture for new builds, additions, and major renovations. The firm also serves nonprofit facilities, community spaces, educational settings, faith-based buildings, and select civic projects. Rotharc operates as a principal-led studio, with Roth working directly with clients from early planning through design, permitting, and construction. This ensures that the architect who evaluates the site and develops the original concept remains engaged as the project progresses.
Roth launched Rotharc after eight years with CBTWO Architects in Salem, where he contributed to multifamily housing, senior living facilities, civic buildings, and community projects. He started in architectural drafting and construction documentation, later becoming a licensed architect in 2021 and moving into project management.
His background includes overseeing a nearly 300-unit apartment development and coordinating clients, engineers, consultants, and public agencies on housing and civic initiatives. “I had an excellent experience at my previous firm and learned from architects, land-use specialists and technical staff with decades of experience,” Roth said. “Over time, I developed a stronger interest in smaller-scale work that is rooted in the community where I live.”
Roth noted that the decision to base the firm in Salem was deliberate. He grew up in Oregon, finished his graduate architecture studies within the state, and has spent the majority of his professional career working in the Salem community. While Salem and the Willamette Valley are the firm’s primary service areas, Rotharc may also take on selected projects elsewhere in Oregon when the client and scope align well. The practice is now accepting inquiries from property owners, developers, nonprofit organizations, and community groups seeking architectural services for multifamily housing, middle housing, custom residences, and civic projects.
“My goal is to build the firm deliberately and take on projects where I can provide direct value,” Roth said. “This initial project is a strong place to begin because it combines housing, local development and a clear community purpose.”
