When Do You Need a Lake Oswego Landscape Architect?
You need a Landscape Architect in Lake Oswego when your project requires a registered professional, such as a public job or one that needs stamped drawings. Most residential yards need a landscape designer working with a licensed contractor. Grover’s Landscape Services & Design works that way as a design-build company, and we’ll say so if your site needs a registered architect instead.
Oregon protects the title, so the answer depends on who is allowed to call themselves what. Below we walk through the state rules, Lake Oswego’s tree permit rules, and what a good plan should contain before anyone starts digging.

What Is the Difference Between a Landscape Architect and a Landscape Designer in Oregon?
In Oregon, a landscape architect is registered with the State Landscape Architect Board, and only registered people may use that title. A landscape designer may plan plants and site features but not supply construction details and specifications. A licensed landscape contractor builds the work. On a residential yard the three roles overlap, and the state draws the lines.
Under ORS 671.316, nobody may use the titles landscape architect, registered landscape architect or landscape architectural designer unless registered. ORS 671.321 leaves other work open: anyone may make plans or drawings for the selection, placement or use of plants or other site features, and may call themselves a landscape designer for it, unless the drawings provide construction details and specifications.
When Do You Actually Need a Registered Landscape Architect?
Three situations come up. The first is a public project, because the state or a local government may contract for landscape architecture service projects only with registered landscape architects. The second is a site that needs technical drawings only a registered professional may prepare. The third is local. For a major forest management permit on a large forested tract, Lake Oswego requires a plan from a forest management professional, a category that includes landscape architects, arborists and foresters. A typical backyard garden, patio and planting job isn’t any of those. For landscape design Lake Oswego homeowners usually start with a designer or a design-build company, and a landscape designer Lake Oswego homeowners hire still needs a licensed builder.
Why Does Lake Oswego’s Tree Code Care About Your Plan?
Do I need a design before landscaping work starts? Often, yes. Oregon requires a written contract describing the work and materials once a job reaches $2,000, and Lake Oswego’s tree permit for a landscape purpose requires a plan that does more than remove a tree and plant replacements.
Lake Oswego’s tree code doesn’t apply to trees under six inches across, but removing a larger tree takes a permit. A simpler Type I permit covers up to two trees of 15 inches or less per year at a single-family home, but not trees inside the 25-foot Oswego Lake Special Setback.
Other removals need a Type II permit. One accepted reason is that the tree has outgrown its landscape area or removal is part of a landscape plan. The city defines that plan as plantings, possibly with walkways, patios and other features, and requires mitigation of a 1.5-inch deciduous tree or a six-foot evergreen for each tree removed. The plan and the permit travel together.
How Does Design-Build Work With a Landscape Designer Near Lake Oswego?
If you’re searching for the best landscape designer near Lake Oswego, ask who stays accountable after the drawing is done. Who designs residential landscapes in Lake Oswego? Independent designers, design-build contractors and registered architects all do, in different ways.
Oregon’s Landscape Contractors Board says design work doesn’t require a license when it contains no construction details or specifications, and that arranging and contracting for the installation does require a landscape or construction contractor license. So which landscape designer near me handles design and build? A design-build company does both under one contract.
Here’s how our landscape design and development service runs. We walk the property, measure it and check slope and drainage. You then get a written design proposal covering scope, design fee and a construction estimate, and our licensed crew builds once you approve it. Our guide to design versus development covers the split.
What Should a Lake Oswego Landscape Plan Include?
Our design work includes scaled site drawings, plant schedules, hardscape layouts, and lighting and irrigation plans built around your property. Garden design and planning Lake Oswego yards need also depends on slope, drainage, the lake setback and which trees stay.
A plan often reaches past the planting beds into hardscape construction, irrigation and sprinkler services and site preparation and excavation. Planning them together avoids a patio that collects water. Our landscape design tips cover Oregon’s wet winters and dry summers.

How Do You Check a Landscape Contractor Before You Sign?
Start with the license number, and ask which board issued it, since a Landscape Contractors Board or Construction Contractors Board license can each cover some landscape work. Then verify it with that board. Grover’s lists Oregon License #100592, and you can check ours the same way.
Next, read the contract. Oregon’s Landscape Contractors Board says it must include the license number, a general description of the work and materials, an estimated completion date, the price and payment schedule, a description of the guarantee, and, since January 2024, a notice of your right to cancel within three business days. Changes must be in writing, and an email or text from both sides counts.
Frequently Asked Questions
How much does landscape design cost in Lake Oswego?
It depends on the size of the property, the scope, and the site, including slope, drainage, existing trees and any lakefront setback. We don’t publish a flat price because it changes from yard to yard. After a site walk, Grover’s gives you a written design proposal that covers the scope, the design fee and an estimate for construction, so you see both before you decide. Ask any company whether its design fee is separate or built into the build price.
What is the difference between a landscape designer and a landscape architect?
In Oregon, a landscape architect is registered with the State Landscape Architect Board, and only registered people may use that title. A landscape designer plans the selection and placement of plants and site features but doesn’t supply construction details and specifications. Public landscape architecture projects require a registered architect, while a typical residential yard usually doesn’t. A designer’s plan then goes to a licensed contractor to build.
Do I need a design before installation work begins?
Yes. Oregon’s contract rules ask for a written description of the work and materials rather than a drawing, but a landscape contract for $2,000 or more has to include that description, and a design is how it gets specific. In Lake Oswego, a tree permit sought for a landscape purpose also expects a plan that includes plantings. Skipping the design usually means paying to fix what the plan would have caught.
Do you provide a plan-view sketch of the proposed design?
Yes. Our design work includes scaled site drawings, plant schedules, hardscape layouts, and lighting and irrigation plans, and you see the full design and pricing before any construction begins. A landscape design drawing shows where plants and features go. It isn’t an engineered structural drawing, so a retaining wall or drainage structure that needs engineering is a separate step.
Can you design and install as a single project?
Yes. Grover’s is a design-build company, so the same team that draws the plan builds it, under one written scope. The design gets your approval first, then our licensed crew handles the site preparation, hardscape, irrigation, planting and lighting on one schedule.
