The tenant improvement work letter is the bid boundary on a Kearny Mesa or Mission Valley suite. It tells you what the landlord funds, what the shell already includes, and what still sits on your side of the job. Read it before anyone prices demo, power, or millwork.
A tenant improvement work letter sets the funded scope
The letter is the construction exhibit on the lease. It names the funded scope, who performs it, and how the tenant improvement allowance is supposed to be spent.
In San Diego office and light industrial deals, that scope is interior work tied to your use of the suite. Think partitions, doors, ceiling grid, lights, flooring, and the HVAC and power that serve those rooms. Desks, chairs, copiers, and moving costs usually don’t count. Those are furniture and operations, not building work.
The letter also draws a line around base building work. A new roof, a shared lobby, or an elevator is the landlord’s capital project. It shouldn’t eat the tenant improvement allowance. If the letter is quiet on that split, the bid gets noisy later.
Turnkey means the landlord is building a defined list and handing you a finished suite. An allowance means you, or your contractor, run the work and the landlord reimburses eligible costs up to a cap. As-is means you take the suite in its current condition and fund the rest. Each shape changes who writes the bid and who holds the trades.
Watch what the allowance will actually pay. Some letters cover hard construction only. Others allow drawings, permit filings, and engineering. Soft costs that fall outside the letter still belong on a bid line. They just won’t come from landlord money.
When we walk a Convoy-corridor office or a Mission Valley suite off Camino del Rio, we read the landlord work letter first. Then we look at the room. The paper and the shell have to match, or the bid is fiction.
How the suite condition changes the remaining work
The remaining tenant scope starts with the condition of the suite on delivery, not with a wish list of finishes.
A true empty shell in Kearny Mesa still needs almost every interior trade. You’re looking at slab or existing floor, exposed structure or an open ceiling, and trunk utilities at the core. Power, data, restrooms, and HVAC distribution may stop at the demising wall. That’s a full build-out on the tenant side once landlord base work is done.
A warm shell is further along. Restroom cores, a ceiling, basic lighting, and HVAC to the suite are often in place. Your remaining work is layout, finishes, and extra capacity. A second-generation suite still holds the last tenant’s rooms, carpet, and lights. Much of that won’t match your plan or the building standard.
Leftover layout is where bids go wrong. People price paint over rooms that have to come out. Or they assume existing HVAC boxes will cover a denser floor plan. Older Mission Valley offices hide mismatched ceiling grid and restrooms that no longer fit the headcount. Light industrial along Ruffin or Clairemont Mesa often hands you a warehouse volume with a small office bump-out that has to grow.
Walk the suite with the work letter and a tape. Confirm what delivered means, including restrooms, HVAC coverage, and power at the panel. None of that is a guess you want from a leasing flyer.
If the suite is vacant, trade sequence is a separate problem. Our vacant suite tenant improvement planning walkthrough covers that order. The work letter is the funding map that sits on top of it. An empty room doesn’t mean an empty scope.
Why drawings and landlord criteria come before demo
Drawings come before demo because the landlord, the city, and the trades all need the same picture.
Most work letters require a space plan, then construction drawings, then landlord approval. Building criteria sit next to those sheets: door hardware, ceiling type, lighting, window coverings, and what you may not touch in the common corridor. Kearny Mesa business parks and Mission Valley office buildings each have their own rules for after-hours work, freight access, and insurance certificates. Those rules belong in the bid notes, not in a surprise email after walls are down.
Demo without approved drawings is how you open a wall the landlord wanted kept. It’s also how you pull a ceiling that held a shared fire line. We don’t start cutting until the plan is agreed and the permit path is clear.
For addresses inside the City of San Diego, which includes Kearny Mesa and Mission Valley, permit intake runs through Development Services. The party named in the work letter should carry that filing. Landlord-performed work and tenant-performed work can each need their own sheets. Don’t assume the landlord’s base-building permit covers your new rooms, your new restroom, or your extra electrical.
Landlord approval isn’t a rubber stamp. If the letter only says subject to approval, expect a slow loop. Better letters name what the landlord may reject: structure, systems, exterior, and building-standard finishes. Your designer should draw to those limits. Change orders after approval are how remaining tenant money disappears.
Samples and cut sheets belong with the drawings when finishes leave the building standard. Carpet, wallcovering, and suite-entry signage get reviewed. A clinic or food use brings water demand and exhaust the office next door never had. Get those on paper early.
Where inspections still apply after landlord work
Landlord work finishing doesn’t close the inspection path for your remaining scope.
City inspectors still look at the work you add. New walls, new exits, electrical, mechanical, plumbing, and accessibility all draw their own inspections even if the landlord already signed off on the shell. A warm-shell delivery can still leave you with a restroom count, a corridor width, or a lighting layout that has to be shown again when you change the plan.
The landlord will also walk the job. Many letters call for a substantial-completion review and a punch list. That walk is about the funded scope, the building standard, and damage to common areas. It’s separate from the city’s card. Passing one doesn’t retire the other.
Fire and life safety is the inspection people forget. A Kearny Mesa office that adds rooms can change sprinkler coverage and horn-strobe layout. A light industrial suite that adds an office mezzanine changes exiting. Those items sit on drawings and on inspection lists. They rarely sit in a furniture budget.
Keep the two closeout piles straight. The city wants permitted work inspected and signed. The landlord wants as-builts, extra keys, and a suite that matches the approved plan. Your contractor should know which pile each item belongs to.
Inspection timing follows the city’s queue and the work that’s ready to show. We schedule walks when the trade is actually done. We keep the work letter, the drawings, and the inspection list on the same table so the remaining bid isn’t missing a trade that only shows up at the end.
What the TI bid should separate from landlord work
A clean commercial suite bid versus landlord work is two columns, not one lump sum.
Column one is work the letter already funds or assigns to the landlord. Column two is remaining tenant work: everything your operation needs that the letter doesn’t buy. If those columns share a line item, you’ll pay twice or fight over who owns the delay.
| Scope | Landlord / work letter | Remaining tenant bid |
|---|---|---|
| Base building to the suite | Structure, main HVAC, and power to the premises when the letter says so | Extra capacity, dedicated units, and distribution for your layout |
| Interior rooms | Building-standard walls and finishes listed in the letter | Custom millwork, branded reception, extra rooms |
| Restrooms | Core restrooms in a warm shell | Fixture upgrades, an extra restroom, finish beyond standard |
| Ceiling and lights | Grid and building-standard fixtures | Specialty lighting, open ceiling, acoustic treatment |
| Drawings and permits | Only if the letter names them as eligible | Design, engineering, and filings the allowance excludes |
| Furniture and equipment | Almost never | Desks, racks, appliances, security, AV |
| Building access rules | Building management process | After-hours labor on the tenant job |
The letter in your lease is the only document that assigns a real item to a real party. Permits, after-hours labor, and HVAC extras are the three that most often slide into the tenant column without anyone saying so out loud.
Ask the bidder to show landlord work as an exclusion, an allowance, or a separate section. If we didn’t perform the landlord’s scope, we shouldn’t bury it inside your number. If we’re bidding only remaining tenant work, the proposal should say that in the first paragraph.
Who holds the contract matters for the same reason. Landlord-performed work uses the landlord’s contractor. Tenant-performed work should use a licensed California contractor you can look up by name or number. You can confirm our license, CSLB #1042918, the same way. For a Kearny Mesa shortlist, start with this Kearny Mesa tenant improvement contractor guide. License first. Building experience second.
Improvements that attach to the building usually stay when you leave. Plan the bid as if the walls and HVAC won’t roll out on a truck. Furniture and trade fixtures are the items to flag if you need them back.
Our commercial remodeling and tenant improvement crews follow that split. We price landlord work only when we’re doing it. We price remaining tenant scope as its own job.
