Commercial tenant improvements
Turn a leased commercial space into a place your business can use
Constructive Solutions plans and builds tenant improvements for commercial clients across San Francisco and the Bay Area. We coordinate preconstruction, trade work, interior construction and turnover around the property, approved documents and project requirements.

A commercial TI partner
Tenant improvement construction begins before work starts on site
A tenant improvement, often shortened to TI, adapts leased commercial space to a tenant’s operational needs. The work can involve selective demolition, new layouts, partitions, ceilings, flooring, millwork, lighting, electrical, plumbing, HVAC coordination and accessibility improvements. The right scope depends on the existing building, intended use, lease terms and approved plans.
Early contractor involvement gives owners, tenants, brokers and design teams a practical construction perspective while important decisions are still being made. Existing conditions, building rules, long-lead materials, utility capacity, permit pathways and landlord requirements can all affect cost and schedule.

What we coordinate
Commercial tenant improvement services
The service plan is built around the project’s current stage, delivery method and documented responsibilities. Typical workstreams may include:
Preconstruction
Develop scope alignment, pricing, schedule logic, trade input, constructability feedback, alternates and procurement priorities as documents advance.
Site logistics
Plan building access, deliveries, temporary protection, communication protocols and construction sequencing for the approved work.
Interior construction
Coordinate demolition, framing, drywall, ceilings, flooring, painting, glazing, doors, hardware, millwork and other specified finish scopes.
Building-system trades
Coordinate documented electrical, lighting, low-voltage, plumbing, mechanical, HVAC and fire-life-safety scopes with the appropriate project partners.
Quality control and turnover
Track field questions, inspections, punch-list work, closeout requirements and turnover items established for the project.
Related delivery capabilities include preconstruction, construction management and design-build.
From lease questions to turnover
A coordinated tenant improvement process
No two commercial spaces begin at the same point. This framework helps organize early discussions without assuming that every project follows an identical sequence.
Illustrative process graphic; it does not depict a specific Constructive Solutions project.
Define the requirements
Confirm the property, intended use, decision-makers, lease responsibilities, design status, target dates and known constraints.
Investigate and price
Review available information, align the preliminary scope, obtain trade input and identify assumptions, exclusions and owner decisions.
Plan and build
Coordinate approved documents, building access, procurement, submittals, field work, inspections and project communication.
Complete and turn over
Resolve punch-list items and organize applicable closeout and turnover requirements for the completed space.
Decisions that shape the project
Lease responsibilities, allowance and delivery method
A lease may identify landlord work, tenant work, reimbursement procedures, approval requirements and a tenant improvement allowance. Those commercial terms should be reviewed with the appropriate legal, real-estate and financial advisers. The contractor’s role is to help translate the approved construction scope into a practical plan, price and schedule.
Our tenant improvement budget and allowance guide explains common terminology and budgeting considerations. The service page does not replace lease, accounting or legal advice.

Related construction terms
Tenant improvement, build-out and fit-out
| Term | How it is commonly used | What matters for planning |
|---|---|---|
| Tenant improvement | Work adapting leased commercial space for a particular tenant or use. | Lease scope, allowance procedures, existing conditions, approvals and operational requirements. |
| Build-out | A broad term for constructing or completing an interior space. | Starting condition, design completeness, trade scope, systems and finish level. |
| Fit-out | Often used interchangeably with interior build-out, depending on the market and project team. | Use the documents and responsibility matrix rather than relying on terminology alone. |

Planning questions
Tenant improvement FAQs
When should a tenant improvement contractor become involved?
Early involvement can be useful while the design and lease-related construction responsibilities are still being clarified. The contractor can review available information, identify construction questions and begin developing scope, pricing and schedule logic. Final lease and design decisions remain with the appropriate parties.
How long does a commercial tenant improvement take?
Duration depends on design completion, approvals, scope, space condition, procurement, inspections, building access and decision timing. A useful schedule should identify both preconstruction activities and field construction rather than presenting one generic duration.
Can work happen in an occupied building?
Many tenant improvements occur in operating commercial buildings. The project plan may need to address working hours, access routes, temporary protection, noise, dust, shutdowns, deliveries and communication with building management. Feasibility depends on the actual scope and building requirements.
What affects tenant improvement cost?
Major variables include existing conditions, intended use, layout complexity, finish selections, building-system upgrades, code requirements, design completeness, schedule constraints and market pricing. Current project documents and trade input are more reliable than a universal per-square-foot number.
Who pays for tenant improvements?
Responsibility varies by lease. A landlord may fund defined work or provide an allowance, while the tenant may fund costs beyond agreed terms. Review the lease with qualified advisers and confirm the construction responsibility matrix before relying on an allowance assumption.
