Commercial Remodeling and Installations

Portland's Commercial General Contractor — Tenant Improvements, Buildouts, and Full-Scope Construction

Commercial construction in Portland runs on a different set of rules than residential work. The permits are harder. The codes are stricter. The stakes are higher — because every day your space isn't finished is a day you're not generating revenue. Boss PDX (CCB #232383) handles commercial projects across the Portland metro, from tenant improvement buildouts in the Pearl District to warehouse conversions in the Central Eastside Industrial District. We hold the licenses, carry the insurance, and know the process inside out — BDS commercial permitting, Oregon Structural Specialty Code, fire and life safety, ADA, and everything else that separates commercial contracting from hanging drywall in someone's basement.

We work with business owners, property managers, landlords, architects, and commercial real estate brokers. Whether you're building out a raw shell, renovating an existing space for a new tenant, or retrofitting a building to meet current code, we bring the project management discipline and trade expertise that commercial work demands.

Tenant Improvement (TI) Buildouts

Tenant improvements are the backbone of commercial contracting in Portland. When a business signs a lease on a space that doesn't match their operational needs, the TI buildout bridges the gap. This work ranges from cosmetic refreshes — new paint, flooring, and lighting — to full gut-and-rebuild projects that reconfigure walls, upgrade mechanical systems, and bring outdated spaces up to current Oregon building code.

A well-run TI project starts before the lease is even signed. We regularly provide preliminary budgets and scope reviews so tenants and landlords can negotiate realistic TI allowances. Too many deals fall apart because the allowance was set without contractor input, and the actual cost of code-required upgrades (fire sprinkler modifications, ADA-compliant restrooms, HVAC redistribution) blows past the number. We help you avoid that.

Our TI work covers every commercial use case:

• Office buildouts — open-plan layouts, private offices, conference rooms, server closets, reception areas, and break rooms
• Retail buildouts — storefronts, fitting rooms, display areas, point-of-sale stations, and customer-facing finishes
• Restaurant and bar buildouts — commercial kitchen construction, hood and ansul systems, grease traps, walk-in coolers, bar plumbing, and health department compliance
• Medical and dental office buildouts — specialized plumbing, medical gas, lead-lined walls for radiology, HIPAA-compliant layouts
• Warehouse and flex-space conversions — adding office space within warehouse shells, mezzanines, demising walls, and loading dock modifications

Every TI project in Portland requires a commercial building permit through the Bureau of Development Services (BDS). Even what seems like a simple interior renovation can trigger code upgrade requirements — particularly around fire sprinklers, seismic bracing, energy code compliance (Oregon Energy Efficiency Specialty Code), and accessibility. We handle the full permit process, from plan submission through final inspection sign-off.

Office Buildouts and Corporate Interiors

Portland's office market spans everything from historic brick-and-timber buildings in Old Town to Class A towers downtown to converted industrial spaces in the Central Eastside. Each building type presents different construction challenges.

In older buildings — and Portland has a lot of them — you're often dealing with unreinforced masonry (URM), outdated electrical panels, and plumbing that predates modern code. An office buildout in a 1920s building on SW Morrison isn't the same project as one in a 2015 concrete-and-steel building in the South Waterfront. We've done both, and we know what surprises to plan for.

Typical office buildout scope includes:

• Demising walls and interior partitions (metal stud and drywall, glass partitions)
• Suspended acoustical ceiling systems or exposed ceiling treatments
• Commercial flooring installation — LVT, carpet tile, polished concrete, epoxy
• Commercial lighting — LED retrofits, task lighting, architectural fixtures, occupancy sensors per Oregon energy code
• HVAC distribution — ductwork modifications, VAV boxes, supplemental cooling for server rooms
• Electrical — dedicated circuits, data/telecom rough-in, panel upgrades
• Fire alarm and sprinkler modifications
• Commercial restroom construction — ADA-compliant fixtures, partitions, and accessories

Restaurant, Bar, and Food Service Buildouts

Portland's food and beverage scene drives a constant flow of restaurant remodel and new buildout work. Building out a restaurant is the most complex type of tenant improvement — it touches every trade and every code section. Mechanical ventilation, commercial kitchen plumbing, Type I and Type II hoods, fire suppression (ansul systems), grease interceptors, walk-in refrigeration, and health department layout requirements all layer on top of the standard commercial buildout scope.

We've built out restaurants, bars, breweries, coffee shops, and commissary kitchens across Portland — from food cart pods stepping up to brick-and-mortar to established restaurant groups expanding into new locations. Our commercial kitchen construction team understands the specific requirements of Multnomah County Health Department inspections and coordinates directly with your kitchen equipment vendors to ensure rough-in specs match final equipment selections.

Restaurant buildouts in Portland also frequently involve liquor license coordination (OLCC), outdoor dining permits, and — in historic districts — design review through the Portland Historic Landmarks Commission. We manage these parallel approval tracks so they don't bottleneck your opening date.

Retail Buildouts

Retail construction in Portland varies dramatically by neighborhood. A boutique buildout on NW 23rd Avenue has different design constraints (and landlord expectations) than a big-box subdivision in a Clackamas strip mall. We work across the full spectrum.

Retail buildouts prioritize the customer experience: storefront presentation, lighting design, traffic flow, fitting rooms, and point-of-sale areas. But behind the scenes, the mechanical and electrical work matters just as much. Insufficient HVAC means uncomfortable customers. Poor lighting means products don't sell. We balance the visible finishes with the systems that make a retail space actually function.

For multi-tenant retail properties, we coordinate closely with property management to minimize disruption to neighboring tenants during construction — controlling noise, dust, and access.

Warehouse Conversions and Adaptive Reuse

Portland's Central Eastside Industrial District, inner SE, and parts of NW Portland have seen a wave of warehouse and industrial building conversions. These projects turn former manufacturing facilities, auto shops, and distribution warehouses into offices, creative studios, event spaces, breweries, and mixed-use developments.

Adaptive reuse projects are complex because they involve change-of-occupancy — the building is being reclassified from one use to another under the Oregon Structural Specialty Code. This often triggers significant code upgrades:

• Seismic retrofitting — Portland sits in the Cascadia Subduction Zone. When a building changes occupancy to a higher-risk category (e.g., from storage to assembly), seismic upgrades are frequently required. This can mean steel moment frames, shear walls, foundation tie-downs, and roof-to-wall connections.
• Fire and life safety upgrades — new sprinkler systems, fire alarm systems, emergency lighting, and exit path compliance
• ADA accessibility — accessible entrances, restrooms, routes of travel, and parking
• Energy code compliance — insulation, window upgrades, and mechanical system efficiency per OEESC

We've completed warehouse conversions ranging from 2,000 to 30,000 square feet. These projects require structural engineering coordination, careful demolition planning (especially in buildings with hazardous materials like asbestos or lead paint), and phased construction sequencing.

ADA Compliance and Accessibility

The Americans with Disabilities Act applies to virtually every commercial space in Portland. When you renovate a commercial building, ADA compliance isn't optional — and it's not just about restrooms. Accessible routes of travel, door widths, threshold heights, counter heights, signage, parking, and ramp slopes all fall under ADA requirements.

Oregon's accessibility code (based on ICC A117.1) adds state-specific requirements on top of federal ADA standards. Portland BDS reviews commercial permit applications for accessibility compliance, and inspectors check it in the field. Getting it wrong means failed inspections, costly rework, and potential legal liability.

Common ADA scope in commercial renovation:

• ADA-compliant restroom construction — grab bars, clearances, fixture heights, accessible stalls
• Accessible entrance modifications — automatic door openers, ramp construction, threshold adjustments
• Interior route-of-travel compliance — hallway widths, door hardware, protruding object clearances
• Accessible parking and signage
• Counter and service window height requirements

We handle ADA compliance as an integrated part of every commercial project — not as an afterthought that gets value-engineered out and creates liability later.

Commercial Mechanical, Electrical, and Plumbing (MEP)

Commercial MEP systems are fundamentally different from residential. Higher voltages, three-phase power, rooftop HVAC units, commercial boilers, backflow prevention assemblies, grease interceptors, fire suppression — these systems require licensed commercial tradespeople and proper engineering.

Commercial HVAC

Portland's climate — mild but damp — creates specific HVAC challenges in commercial spaces. Proper ventilation and humidity control prevent mold issues that plague poorly designed commercial interiors. We install and modify rooftop units (RTUs), split systems, VRF systems, and dedicated outdoor air systems (DOAS). For restaurants, we handle the makeup air calculations that balance kitchen exhaust with conditioned supply air.

Commercial Electrical

Commercial electrical work in Oregon requires a licensed electrical contractor. We coordinate 200A to 1200A+ service upgrades, three-phase power distribution, sub-panel installations, dedicated equipment circuits, emergency and exit lighting, and fire alarm system integration. For office buildouts, we rough-in structured cabling pathways and coordinate with your IT vendor on data and telecom infrastructure.

Commercial Plumbing

Commercial plumbing covers more ground than most people realize. Beyond standard fixtures, commercial projects often require backflow prevention devices (required by Portland Water Bureau), grease interceptors for food service, medical gas piping, and concrete work for below-slab plumbing relocations. Sanitary waste and storm drainage modifications on commercial properties require engineering and BDS permits.

Fire Suppression and Life Safety

Most commercial spaces in Portland are required to have fire sprinkler systems. Any modification to the ceiling grid, wall layout, or occupancy of a sprinklered space requires the sprinkler system to be reviewed and potentially modified to maintain coverage. This is one of the most commonly overlooked costs in commercial TI budgets.

We coordinate with licensed fire protection contractors to handle sprinkler head relocations, new branch lines, and system modifications. We also manage fire alarm system work — adding or relocating pull stations, smoke detectors, horn/strobes, and ensuring the fire alarm control panel (FACP) is properly programmed and inspected by Portland Fire & Rescue.

Commercial Permits and Inspections in Portland

Portland's Bureau of Development Services (BDS) handles commercial building permits. The commercial permit process is more rigorous than residential:

• Plan review — commercial plans are reviewed by multiple BDS sections: structural, mechanical, electrical, plumbing, fire/life safety, and accessibility. Review times range from 4-8 weeks for straightforward TI projects to 12+ weeks for complex or change-of-occupancy projects.
• Pre-application conferences — for larger projects or change-of-occupancy, a pre-application conference with BDS is strongly recommended. We've been through enough of these to know which projects need one and which don't.
• Inspections — commercial projects require more inspection milestones than residential. Typical inspections include footing/foundation, underground plumbing, rough framing, rough electrical, rough mechanical, rough plumbing, insulation, fire sprinkler, fire alarm, lath, and final.
• Certificate of Occupancy (CO) — you cannot legally occupy a commercial space until BDS issues the CO. This requires passing all final inspections, including fire marshal sign-off.

We manage the entire permit lifecycle — application preparation, plan submission, examiner responses, inspection scheduling, and CO issuance. Our project managers have direct working relationships with BDS staff and understand how to keep projects moving through the review and inspection process without unnecessary delays.

Phased Construction and Minimizing Business Disruption

Many commercial renovation projects happen in occupied buildings — sometimes in the very space where a business is operating. Phased construction planning isn't a nice-to-have; it's a requirement for keeping your business running while the work gets done.

We develop phased construction plans that isolate work areas from occupied spaces using temporary barriers, dust containment systems (including negative air pressure), and carefully scheduled noise-intensive work during off-hours. For retail and restaurant renovations, we commonly work nights and weekends to minimize impact on business operations.

Phased construction adds complexity to project management — each phase has its own mobilization, material staging, and inspection sequence. We build this into the project schedule upfront so there are no surprises on timeline or cost.

Commercial vs. Residential Construction — Why It Matters

Business owners sometimes wonder why commercial construction costs more per square foot than residential. The reasons are structural:

• Code requirements — commercial buildings are held to the Oregon Structural Specialty Code, which has stricter requirements for fire resistance, structural loading, accessibility, and exiting than the Oregon Residential Specialty Code. These requirements directly increase material and labor costs.
• Permit complexity — commercial permits go through multiple review disciplines and take longer to obtain. Permit fees are higher. More inspections are required.
• Insurance and licensing — commercial work requires higher liability limits, and many trades require specific commercial licensing or certifications.
• Prevailing wage — public and some publicly-funded commercial projects in Oregon require prevailing wage rates under BOLI requirements.
• Material specifications — commercial-grade materials (fire-rated assemblies, commercial hardware, institutional fixtures) cost more than their residential equivalents.
• Schedule pressure — commercial projects often have lease-driven deadlines, opening dates, or occupancy requirements that demand accelerated schedules and the associated costs.

The premium you pay for commercial construction isn't markup — it's the cost of doing the work right in a more demanding regulatory and performance environment.

Commercial Construction Costs in Portland

Commercial construction costs in Portland vary widely based on scope, but here are realistic ranges for 2026:

• Basic office TI (cosmetic) — $45-$75 per square foot. Paint, flooring, minor electrical, furniture-ready.
• Standard office buildout — $85-$150 per square foot. New walls, ceilings, lighting, HVAC modifications, basic finishes.
• Retail buildout — $75-$175 per square foot depending on finishes and storefront work.
• Restaurant/bar buildout — $150-$350+ per square foot. Kitchen buildouts, hood systems, specialized plumbing, and high-end finishes push costs up significantly.
• Warehouse conversion — $100-$250 per square foot depending on seismic, mechanical, and accessibility scope.
• Medical/dental office — $125-$250 per square foot. Specialized systems and infection control requirements add cost.

These ranges assume Portland-area labor rates and current material pricing. Actual costs depend on existing conditions, code requirements, finish levels, and schedule constraints.

Our Commercial Project Management Approach

Commercial projects live and die on project management. A missed inspection delays the next phase. An uncoordinated subcontractor holds up the critical path. A permit revision adds three weeks. These cascading delays cost money — your money.

Every Boss PDX commercial project gets a dedicated project manager who owns the schedule, coordinates trades, manages the permit process, and communicates progress to all stakeholders. We use structured scheduling with clear milestones, weekly progress reporting, and proactive issue resolution. Our project managers don't wait for problems to become crises — they identify risks early and address them before they impact your timeline or budget.

For larger projects, we provide detailed construction schedules, regular owner-architect-contractor (OAC) meetings, RFI tracking, submittal management, and change order documentation. This isn't overhead — it's how commercial projects stay on track.

Frequently Asked Questions

How long does a commercial tenant improvement take in Portland?

Timeline depends on scope and permit complexity. A cosmetic TI (paint, flooring, lighting) in an existing permitted space can take 2-4 weeks of construction. A full office buildout with wall construction, MEP work, and ceiling systems typically runs 6-12 weeks. Restaurant buildouts with commercial kitchen construction often take 10-16 weeks. Add 4-8 weeks on the front end for BDS commercial plan review and permitting. We provide detailed project schedules during the estimating phase so you can plan your lease start date and business opening accordingly.

Do I need a permit for a commercial remodel in Portland?

Almost always, yes. Portland BDS requires commercial building permits for any work that modifies walls, ceilings, electrical systems, plumbing, mechanical systems, or fire protection systems. Even "cosmetic" renovations can trigger permit requirements if they affect accessibility, egress, or fire-rated assemblies. Working without permits in a commercial space creates serious liability — it can void your insurance, violate your lease, and result in BDS enforcement action including stop-work orders and fines. We pull all required permits and manage the inspection process.

What is the difference between a TI allowance and actual construction cost?

A tenant improvement allowance is the dollar amount a landlord contributes toward buildout of the space, typically negotiated as part of the lease (expressed as dollars per square foot). The actual construction cost is what the work costs to build. These numbers are often different — sometimes significantly. A landlord might offer $40/SF TI allowance on a space that needs $120/SF in construction to meet the tenant's needs. The tenant pays the difference. We help tenants and landlords align TI allowances with realistic construction budgets before the lease is signed, which prevents disputes and project delays later.

Can you work nights and weekends to avoid disrupting my business?

Yes. We regularly perform commercial renovation work during off-hours to minimize disruption to operating businesses. This is common for restaurant renovations, retail remodels, and office renovations in occupied buildings. Off-hours work may carry a premium for overtime labor rates, but it's often worth it to keep revenue flowing during construction. We'll build a phased construction plan that balances cost, timeline, and business continuity.

What commercial trades do you self-perform vs. subcontract?

We self-perform general carpentry, framing, drywall, doors and hardware, finish carpentry, and project management. We subcontract licensed specialty trades: electrical, plumbing, HVAC, fire sprinkler, fire alarm, roofing, and structural steel. All subcontractors carry their own Oregon licenses, insurance, and bonding. We manage all subcontractors directly — you have one point of contact and one contract, not a dozen.

Do you handle commercial seismic retrofits?

Yes. Portland has a large inventory of unreinforced masonry (URM) buildings, and the city's URM retrofit mandate is driving significant seismic upgrade work. We also handle seismic upgrades triggered by change-of-occupancy or substantial renovation thresholds under the Oregon Structural Specialty Code. Seismic retrofit work requires structural engineering design — we coordinate with licensed structural engineers and handle the construction execution, from steel moment frame installation to foundation modifications.
