What it is
Structural changes in TI projects: what triggers engineering and permits is a planning topic. The goal is not to memorize rules. The goal is to make decisions in the right order so the build is predictable.
Why it matters
When this is planned well, your project feels calmer. The schedule becomes easier to protect and the budget becomes easier to control.
Step by step approach
- Create a test fit layout and confirm accessibility impacts
- Coordinate engineering and life safety early
- Confirm lease responsibilities and landlord approval process
- Write the business program: people, equipment, brand feel, opening date
- Close out with inspections, training, manuals, and warranties
- Plan phasing to protect operations and keep access clear
- Order long lead items as soon as the permit set is stable
Use this list as a decision sequence. Planning time is cheaper than construction time.
Deep dive
Deep dive
This topic becomes easier when you focus on a clear sequence of decisions and written documentation. Use the checklists below as your anchor.
Scope starter
If you need to request bids or align expectations, use this starter scope template and customize it for your project.
Commercial scope starter Space address and suite number Business program and equipment list Demolition and prep scope Walls, ceilings, doors, glazing Mechanical electrical plumbing scope Life safety and accessibility scope Finishes and brand elements Phasing and access constraints Closeout documents and training
San Diego considerations
Commercial permits often involve multiple disciplines and reviews. Coordinate landlord approvals in parallel.
San Diego note
If your project is in San Diego County, confirm requirements with the City or County office that covers your address.
Decision matrix
Use this quick matrix to choose an approach that fits your priorities.
| Option | Best for | Tradeoffs |
|---|---|---|
| After hours work | Protect customers and staff | Premium labor and noise constraints |
| Full shutdown build | Fastest construction sequence | Lost revenue during closure |
| Phased build | Keep operations open | More coordination, may cost more |
Cost and timeline drivers
Most surprises are predictable when you know where they come from. Use these lists to plan and to compare options.
Cost drivers
- Lease and landlord standards
- Accessibility impacts and path of travel scope
- Phasing and after hours work
- Mechanical and electrical upgrades for equipment
- Fire and life safety coordination
- Durability requirements for high traffic finishes
- Long lead items such as HVAC and doors
- Plan review corrections and resubmittals
Timeline drivers
- Night or weekend work constraints
- Long lead items tied to opening date
- Plan review and correction cycles
- Inspections and sign offs for turnover
- Landlord approvals and coordination meetings
Planning tip
Documentation reduces unknowns. Unknowns create cost and schedule risk.
Documents to gather
Projects move faster when the right information is ready. This list is a practical starting point.
- Permit set and engineering documents
- Long lead procurement list with target dates
- Business program and equipment list
- Test fit layout and customer flow diagram
- Lease responsibility summary and landlord standards
- Closeout manuals, warranties, and training checklist
- Safety and phasing plan if occupied
Questions to ask

- How will accessibility and life safety be addressed
- What approvals are required from the landlord and when
- What long lead items could affect the opening date
- What is the realistic plan review timeline for this scope

Usually the design team and contractor coordinate, but roles must be clear in writing before permitting.
What should I expect at turnover
Expect a punch list period plus manuals, warranties, and basic training for building systems.
What is the first step in structural changes tenant improvement
Define the business program and opening date, then confirm lease responsibilities and required approvals.
