What Commercial Tree Work Can MTS Handle Under One Scope?

MTS can combine scheduled pruning, hazard-tree assessment, tree removal, stump grinding, storm response, parking-lot tree care, lot clearing, and related landscape work into one commercial scope. Recurring properties can also be scheduled seasonally instead of treating every tree issue as a separate project.

That matters when a property has more than one type of tree work to manage.

A commercial scope can cover:

• Common-area pruning
• Dead or broken branch removal
• Clearance around buildings and access routes
• Parking-lot tree maintenance
• Hazard-tree assessments
• Tree removal
• Stump grinding
• Storm-damaged trees
• Lot clearing
• Landscape restoration after tree work

MTS's current King County commercial tree-trimming service specifically advertises ongoing commercial contracts with scheduled seasonal service, documented work, and after-hours scheduling. Its Bellevue commercial work also includes regular pruning schedules, hazard-tree assessments, parking-lot tree care, and storm response for HOAs and property-management clients.

The scope should still be built around the property rather than a standard package. An office park with mature parking-lot trees has different access, pedestrian, and scheduling requirements from an HOA with wooded common areas.

How Should an HOA or Property Manager Plan Annual Tree Maintenance?

Start with a current tree inventory, separate immediate hazards from planned maintenance, define the properties and common areas covered, and turn that information into an annual scope with scheduled work, a process for approving additional work, storm-response terms, reporting, and a budget for unplanned tree failures.

That creates a plan the board, property manager, and contractor can all work from.

1. Know What You Are Managing

For a small community, that may simply mean identifying the trees in common areas.

Larger communities may benefit from an inventory that records:

• Tree location
• Species
• Approximate size
• Condition
• Priority
• Recommended work
• Previous work where records exist

The goal is not to create paperwork for every tree. It is to stop the same trees from being rediscovered every time the board changes or a new property manager takes over.

2. Separate Urgent Work From Planned Work

Dead branches over a walkway and routine clearance pruning should not compete for attention in the same way.

A practical maintenance plan separates:

Immediate issues

• Active failures
• Confirmed hazardous conditions
• Broken or hanging limbs
• Blocked access

Planned work

• Structural pruning
• Clearance
• Stump grinding
• Removals that can be scheduled
• Landscape restoration

3. Define the Contract Scope Clearly

A commercial tree-care scope should identify:

• Properties and addresses included
• Common areas covered
• Scheduled services
• What requires separate approval
• Emergency contact process
• Debris and wood handling
• Stump-grinding scope
• Site-access restrictions
• Work-hour restrictions
• Documentation expected after service
• How additional work will be authorized

Avoid vague language such as “maintain all trees as needed.” It is difficult to budget, price, or manage consistently.

4. Budget for Work That Cannot Be Predicted

No annual maintenance plan can predict every storm failure.

A better budget separates known maintenance from a reserve for unscheduled removals, storm damage, or newly identified hazards.

MTS currently advertises ongoing commercial and HOA tree-maintenance work rather than only one-off residential jobs.

When Does an HOA Need a Maintenance Contract Instead of One-Off Tree Calls?

A recurring agreement makes sense when an HOA has enough trees, common areas, sites, or annual work that handling every pruning, removal, and storm issue as a separate quote starts creating inconsistent budgets, incomplete records, and repeated vendor coordination.

Common signs include:

• Several common areas
• Multiple association properties
• A large mature-tree population
• Regular pruning or clearance work
• Repeated storm calls
• Frequent board turnover
• No reliable record of previous tree work
• Annual tree spending that is difficult to forecast
• A management company coordinating several communities

A contract does not need to mean every tree is pruned every year.

In fact, it should not.

Tree work should be scheduled around actual conditions, species, objectives, site use, and priority rather than applying one universal pruning interval across the property.

The value of the contract is the management structure: known sites, agreed scope, established contacts, documented work, and a clear route for approving work outside the plan.

How Does MTS Handle Multi-Site and Occupied Commercial Properties?

Commercial tree work should be planned around the people and operations already using the site. That means accounting for parking, tenant access, delivery areas, customer traffic, pedestrian routes, equipment staging, debris removal, and the hours when work can be completed with the least disruption.

This becomes especially important at:

• Retail centers
• Office properties
• Apartment communities
• HOA common areas
• Parking lots
• Schools or institutional properties
• Multi-building sites

Before work starts, the site contact should identify:

• Restricted parking areas
• Gates or access codes
• Loading areas
• High-traffic periods
• Tenant or resident notification requirements
• Noise restrictions
• Areas that cannot be blocked
• Where equipment can stage safely

MTS advertises after-hours scheduling for commercial tree work and flexible scheduling for commercial, HOA, and property-management customers. Availability still needs to be confirmed for the specific property and scope.

For sites that need planting, landscape installation, or ongoing landscape work alongside tree services, MTS also provides commercial landscaping and coordinates larger commercial projects with civil engineers, architects, and general contractors.

What Tree Work Should Be Planned Before New Construction Starts?

Before clearing starts, the project team should identify the permitting jurisdiction, map the trees to retain or remove, check for critical areas and buffers, establish tree-protection requirements, and coordinate approved tree work with access, grading, utilities, and the construction schedule.

The jurisdiction matters.

“King County” does not mean one set of tree rules.

The county's clearing and grading regulations apply to unincorporated King County. Seattle, Bellevue, Sammamish, Issaquah, Redmond, Renton, Kirkland, and other incorporated cities have their own tree and development requirements.

What Requires a Clearing Permit in Unincorporated King County?

King County requires a clearing permit for vegetation removal in critical areas, properties subject to urban clearing standards or certain special-district clearing restrictions, clearing more than 7,000 square feet on RA-zoned property, and removal of 5,000 board feet or more of merchantable timber.

Those are county rules for unincorporated areas.

A project inside an incorporated city needs to be checked against that city's current code instead.

Review King County clearing and grading requirements

What About Critical Areas?

Wetlands, streams, steep slopes, flood areas, and regulated buffers can change what clearing or grading is allowed.

That is why critical-area review belongs early in the project, not after equipment arrives.

The practical sequence is:

1. Confirm jurisdiction.
2. Review mapped and site-specific constraints.
3. Identify retained and proposed-removal trees.
4. Determine what professional tree documentation is required.
5. Obtain permits or approvals.
6. Mark protection and work areas.
7. Begin authorized clearing.

For projects that need professional tree inventories, condition documentation, or retained-tree recommendations, MTS also provides arborist consultations and tree assessments.

What Does MTS Do During the Construction Sequence?

Commercial tree work can start before earthwork with tree assessment and removal planning, continue through site preparation with approved clearing and stump work, and return later for planting, mulch, or landscape installation. The tree scope should be coordinated with the construction sequence rather than treated as a stand-alone cleanup task.

Project Phase	Potential Tree / Landscape Scope	Key Decision	Typical Deliverable
Pre-design / permit	Tree review, inventory, retention/removal planning	What stays and what conflicts with the project?	Tree information or plan required by the jurisdiction
Pre-construction	Approved removals and tree-protection setup	Has the permitted work area been clearly identified?	Marked removals and protected trees
Site preparation	Clearing, stump grinding, debris handling	How does tree work coordinate with grading and access?	Cleared work area
Active construction	Protection of retained trees, if contracted	Is construction staying outside protected areas?	Site observations or corrective recommendations
Closeout	Cleanup, planting, mulch, landscape work	What landscape scope is required at completion?	Finished site/landscape work

Not every project requires an arborist report, tree survey, or tree protection plan.

The local jurisdiction and permit conditions determine that.

What Changes on Municipal and Other Publicly Funded Tree Work?

Publicly funded tree, landscape, or grounds-maintenance work in Washington can trigger public-works requirements that do not apply to ordinary private commercial work. When public funding and public-works criteria apply, landscape construction and grounds maintenance can be subject to prevailing wage, Intent and Affidavit filings, and certified payroll requirements.

Washington L&I identifies landscape construction and grounds maintenance among work that can qualify when a project uses public funds and includes construction, reconstruction, maintenance, or repair.

For applicable public works, contractor requirements can include:

• Valid UBI
• Current contractor registration or other required licensing
• Industrial insurance for employees
• No current debarment
• Public-works training unless an exemption applies
• Prevailing wage
• Statement of Intent to Pay Prevailing Wages
• Certified payroll
• Affidavit of Wages Paid

L&I says contractors and subcontractors bidding prevailing-wage work must meet responsible-bidder requirements, and certified payroll is required on public works projects.

Insurance, bonding, references, and other procurement requirements should come directly from the solicitation.

A public buyer should not assume that a contractor's ordinary commercial qualifications automatically satisfy a specific public-works bid.

Likewise, MTS should not be represented as holding municipal contracts, public-works eligibility, or a specific bonding capacity unless those credentials are confirmed for the project.

What Should a Commercial Buyer Verify Before Awarding Tree Work?

Before awarding commercial tree work in Washington, verify the contractor's current state registration, bond and liability-insurance status, workers' compensation coverage where applicable, relevant arborist credentials, and the written scope. Public work requires additional procurement and prevailing-wage checks.

Washington L&I's Verify tool allows buyers to check registration status, workers' compensation accounts, bond information, citations, and other contractor records.

What to Verify	Why It Matters	How to Check	Project-Specific Addition
WA contractor registration	Confirms current registration status	Washington L&I	Confirm required classification where relevant
Bond and liability insurance	Core contractor-registration requirements	L&I + current contractor documents	Contract may require higher limits
Workers' comp	Confirms employee coverage status	L&I Verify	Check during vendor onboarding
Arborist credential	Verifies the named professional's credential	ISA credential directory	Require a named arborist when the scope calls for one
Written scope	Makes competing proposals comparable	Contractor proposal	Define sites, trees, cleanup and exclusions
COI / endorsements	Documents contract-specific coverage	Contractor/insurance agent	Follow owner's actual insurance requirements
Public-works documentation	Required for applicable public work	L&I / awarding agency	Prevailing wage, Intent, payroll and Affidavit

Washington currently requires registered contractors to maintain a surety bond and general liability insurance. Minimum state registration requirements should not be confused with the higher insurance limits a particular commercial owner, GC, HOA, or public agency may require.

How Is Commercial Tree Work Priced?

Commercial tree work is usually quoted from the defined scope: number and size of trees, number of properties, equipment access, debris handling, work-hour restrictions, site operations, required documentation, permits, and whether the work is recurring or a one-time project.

That is more useful than comparing a commercial property to a generic residential “price per tree.”

Potential proposal structures can include:

• Per-project pricing
• Per-tree or unit pricing
• Defined recurring maintenance scope
• Site-specific annual scope
• Separate pricing for approved additional work
• Separate emergency or after-hours work where offered

The actual structure should be stated in the proposal.

What Should You Send for a Useful Commercial Bid?

Provide as much of this as you have:

• Site address
• Additional property addresses
• Property/site plan
• Existing tree inventory
• Known problem trees
• Photos
• Desired services
• Access restrictions
• Parking or tenant restrictions
• Permitted work hours
• Bid deadline
• Insurance requirements
• Required proposal format
• Construction or permit documents
• Contact for site access

A detailed scope also makes competing bids easier to compare.

Two contractors may quote very different numbers because one has included stump grinding, haul-away, traffic control, after-hours work, or permit coordination and the other has not.

What Should Be Included in a Commercial Tree-Care Proposal?

A useful commercial proposal should identify the sites and work covered, price the agreed scope, explain cleanup and debris responsibilities, define access and scheduling assumptions, identify exclusions and optional work, and provide the contractor information needed for vendor onboarding.

Look for:

• Client and property name
• Service address or addresses
• Trees or areas included
• Type of pruning/removal work
• Stump-grinding scope
• Cleanup and disposal
• Equipment/access assumptions
• Parking or tenant restrictions
• Work window
• Permit responsibility
• Additional-work approval process
• Pricing
• Applicable taxes
• Requested insurance documentation
• Exclusions
• Proposal validity and contract terms

For recurring work, the proposal should also make clear what is scheduled and what remains on-demand.

That distinction is important.

A maintenance agreement should not create the impression that every tree will be pruned every year when no pruning is needed.

Why Use One Commercial Tree and Landscape Vendor?

Using one vendor can simplify coordination when a property needs tree removal, stump grinding, mulch, landscape maintenance, or post-construction planting as part of the same project. The practical advantage is fewer handoffs and one site contact for related outdoor work.

MTS currently provides both commercial tree work and commercial landscaping, including planting and landscape work for parking lots, entry areas, foundation plantings, and other commercial spaces. Its commercial landscaping page also states that larger projects are coordinated with civil engineers, architects, and general contractors.

That can be particularly useful when:

• A removed tree leaves a planting area to restore
• Several stumps need to be cleared before new landscaping
• Construction needs both clearing and finish planting
• An HOA wants tree and landscape work coordinated
• A commercial site has tree and planting maintenance in the same work area

It does not mean every project should be bundled.

The scopes should still be separated clearly enough that the buyer knows exactly what is included.

Commercial Tree Care FAQ

Can MTS service several commercial properties under one schedule?

MTS currently advertises ongoing commercial tree contracts, scheduled seasonal service, documented work, and commercial property-management experience. For a multi-site portfolio, provide the addresses, approximate scope, access restrictions, and administrative requirements so MTS can confirm how the properties can be scheduled.

Can commercial tree work be scheduled outside normal business hours?

Yes, for qualifying projects. MTS currently advertises after-hours scheduling for commercial tree work. Availability should still be confirmed for the particular site, equipment, local noise restrictions, crew schedule, and work window before it is included in the project plan.

Do developers always need an arborist report before clearing land in King County?

No. The requirement is determined by the property's jurisdiction and proposed work. In unincorporated King County, certain critical-area and larger clearing activities require permits. Incorporated cities use their own tree, clearing, and development rules.

Can MTS handle tree work and post-construction landscaping?

Yes. MTS currently provides commercial tree services and commercial landscaping. Its landscaping scope includes commercial sites, and MTS states that it coordinates larger projects with civil engineers, architects, and general contractors.

Does commercial tree work require prevailing wages?

Private commercial work does not automatically trigger Washington prevailing-wage law. Publicly funded construction, maintenance, and repair can. Washington L&I specifically includes landscape construction and grounds maintenance when the public-funding and public-works criteria are met.

What should an HOA send when requesting a tree-service bid?

Send the property addresses, common areas included, existing tree inventory if available, known hazards or removals, desired maintenance work, access restrictions, insurance requirements, proposal deadline, and the person authorized to approve additional work. That gives contractors enough information to quote a comparable scope.
