How long should I wait before requesting a landlord TI allowance increase in 2027?

The end-to-end buildout process and where the allowance ask fits

Tenant improvement allowances are not a standalone negotiation. They are one line in a sequence that starts long before drywall and ends long after occupancy, and the timing of your request only makes sense if you understand where you sit in that sequence.

The typical commercial buildout runs in seven phases. First comes space selection and letter of intent — this is where the TI number first appears, usually expressed as dollars per rentable square foot. Second is lease negotiation, where that LOI number gets papered into a work letter exhibit with conditions attached. Third is test fit and space planning, where an architect produces a preliminary layout and you discover whether the number you agreed to actually covers what you drew. Fourth is construction documents, the full permit set. Fifth is bidding and GC selection, where real pricing lands and the gap between allowance and cost becomes concrete. Sixth is permitting and construction. Seventh is punch list, certificate of occupancy, and allowance disbursement.

The single most important thing to understand about timing: your leverage is highest in phases one and two, and it collapses sharply after phase four. Once you have signed a lease with a stated allowance and produced construction documents, you have already committed. The landlord knows you cannot easily walk. Asking for an increase at phase five — when bids come in high — is the most common request and the weakest position.

That said, phase five requests are not hopeless. They succeed when tied to a documented scope change that the landlord's own requirements caused. If the building engineer required a larger electrical panel, if code review triggered a sprinkler head reconfiguration, if the landlord's base building was delivered out of spec — those are landlord-caused costs and a well-documented change order log gives you a legitimate ask that has nothing to do with your budget discipline.

The practical waiting rule breaks down like this. If you are pre-lease, do not wait at all — negotiate the number now, because this is the only moment you hold real cards. If you are mid-term with 18-plus months remaining, wait until you have either an expansion need, a renewal window opening, or a landlord-side event (building refinance, sale process, occupancy drop) that changes their calculus. If you are inside the renewal window, 60 to 120 days out is the sweet spot: close enough that the landlord is genuinely worried about a vacancy, far enough out that they have time to underwrite the incremental cost.

One nuance worth internalizing: the disbursement mechanics matter as much as the headline number. A $60 per square foot allowance paid as reimbursement after lien waivers is worth materially less than the same number paid progressively against approved draws, because you are float-financing the entire project. If you cannot win a higher number, win better payment terms — many landlords who will not move on dollars will move on timing, and that is often the more valuable concession for a company managing cash.

Roles: landlord, tenant, GC, and architect — who actually decides

Requesting an increase means knowing who you are asking. In most commercial deals the person you talk to is not the person who approves.

The landlord is rarely a single individual. In institutional ownership you are dealing with an asset manager who reports to a fund with return targets, a leasing agent who is compensated on deal volume and rent, and sometimes a property manager who controls construction oversight. The asset manager runs the numbers on net effective rent — total rent over the term minus concessions, discounted to present value. When you ask for a TI increase, you are asking them to accept a lower net effective rate unless you give something back. Understanding this reframes the conversation: an incremental allowance is almost always purchasable with term, rent, or flexibility. Two extra years, a slightly higher base rate in years four and five, a waived termination option — these are the currencies.

The tenant side is usually you plus a tenant rep broker. The broker's incentive is to close, and their commission is a function of total lease value, which means they are not automatically aligned with you on aggressive concession-chasing. That does not make them adversarial, but it means you should be explicit about priorities early. A good tenant rep will tell you what comparable deals in the submarket actually cleared at — that comp data is the single most useful input to your request, and it is information you cannot generate yourself.

The general contractor matters more than most tenants realize. GC selection determines whether your buildout comes in at the allowance or 40 percent over it. Landlords frequently require you to use their preferred contractor list, which reduces competitive tension. If you have any negotiating room, push for the right to competitively bid to at least three qualified GCs, including one of your choosing. The spread between a landlord-designated GC and a competitively bid GC on the same drawings is often 10 to 20 percent — which may be larger than the allowance increase you are chasing. Solving the cost problem from the supply side is sometimes easier than solving it from the landlord side.

The architect shapes cost more than any other party, and does so before anyone is watching. Ceiling treatments, glass front offices, custom millwork, and specialty lighting are where budgets die. Bring the architect into the allowance conversation early and give them a hard number to design to, not a wish list to price. A test fit priced at the allowance number, produced before you finalize lease terms, is the strongest possible evidence when you request an increase — you are no longer saying "I think I need more," you are saying "here is a permit-ready drawing and a real bid showing the gap."

There is also a fifth party people forget: the project manager or owner's rep. On buildouts over roughly 10,000 square feet, hiring an independent owner's rep for a fee — often a percentage of project cost or a flat monthly rate — routinely pays for itself in change order discipline alone. They also know what the landlord's construction group will and will not fund, because they have negotiated against them before.

Real cost ranges, contingencies, and what your allowance actually covers

Numbers vary enormously by market, building class, and use type, so treat any range as a starting frame rather than a benchmark. The useful discipline is not memorizing figures but knowing which cost categories exist and which ones the allowance typically excludes.

Standard office buildouts break roughly into: demolition, framing and drywall, ceilings, flooring, doors and hardware, millwork, painting, electrical, mechanical (HVAC distribution), plumbing, fire protection, low voltage and data cabling, and finally general conditions plus GC fee. General conditions and fee together commonly run 15 to 25 percent of hard costs. Soft costs — architecture, engineering, permits, expediting, and project management — typically add another 10 to 20 percent on top of hard costs.

Here is the trap: many work letters define the allowance as applicable only to "hard construction costs," explicitly excluding furniture, cabling, security systems, audiovisual equipment, moving expenses, and sometimes even architectural fees. A generous-sounding allowance can leave you funding a substantial out-of-pocket amount you never budgeted. Before requesting an increase, read the exclusion list. Sometimes the more winnable ask is not more dollars but broader eligibility — expanding the allowance to cover soft costs and cabling can be worth as much as a headline bump, and it is a smaller-sounding concession for the landlord to approve.

Use type drives cost dramatically. A shell-condition space with no existing HVAC distribution, no ceiling grid, and no electrical distribution costs multiples of a second-generation space with usable infrastructure. Second-generation space — where a prior tenant left conference rooms, restrooms, and a functioning mechanical system — is frequently the cheapest path to occupancy, and taking a slightly less ideal layout in a second-gen suite can eliminate the entire allowance problem. Specialty uses escalate further: labs need fume hoods and specialized exhaust, restaurants need grease interceptors and hood systems, medical needs lead shielding and specialized plumbing, and data-heavy uses need redundant power and cooling. If your use is specialized, your allowance conversation is a fundamentally different negotiation and comparable office numbers will mislead you.

On contingency: carry 10 to 15 percent on a second-generation space and 15 to 20 percent on shell or older buildings where you cannot see behind the walls. Buildings constructed before roughly 1990 carry meaningful risk of asbestos-containing materials in flooring mastic, ceiling tile, and pipe insulation. Discovery mid-construction stops the job and triggers abatement costs and schedule delay. Negotiate hazardous-material remediation as a landlord obligation outside the allowance — this is standard and generally winnable, and it removes a category of catastrophic overrun from your ledger.

Two more allowance mechanics worth understanding. Amortized additional allowance: many landlords will fund above-standard TI in exchange for repaying it through rent at a stated interest rate over the term. This is effectively a loan from your landlord. Compare that rate against your actual cost of capital — if you can borrow more cheaply, or if you have cash, funding it yourself may be better. If your capital is scarce or expensive, landlord-amortized TI can be genuinely attractive financing. Unused allowance: most work letters let the landlord keep whatever you do not spend. Negotiate for unused amounts to convert to a rent credit, even at a partial ratio. Landlords resist, but partial conversion is achievable and it removes the perverse incentive to spend the full allowance on things you do not need.

Common commercial pitfalls that cost more than the increase you're chasing

The failure modes here repeat with remarkable consistency across markets and deal sizes.

Asking without comps. A request unsupported by market data reads as a budget problem. A request supported by three recent comparable deals in the same submarket at higher allowance levels reads as a market correction. Your tenant rep broker has this data. Get it before you ask, and lead with it.

Asking at the wrong point in the landlord's fiscal calendar. Institutional owners have budget cycles, and leasing teams have quarterly and annual targets. A deal that closes in the final weeks of a quarter or fiscal year frequently gets concessions that the same deal would not receive six weeks earlier. This is not a guarantee, but if your timing is flexible, ask a broker who works that ownership group when their pressure points fall.

Treating the allowance as the only lever. Free rent, a reduced base rate, an expansion option, a right of first offer on adjacent space, a termination right, and reduced parking charges are all negotiable and all have quantifiable value. Landlords have strong preferences among these — free rent hits current cash flow but preserves the headline rent used in building valuation, while TI is a capital outlay. Some owners will trade months of free rent far more readily than allowance dollars. Ask which they prefer and let them tell you where the cheap concession is.

Signing a work letter with vague base-building delivery conditions. If the lease does not precisely define the condition of the space at delivery — demised walls closed, HVAC operational and adequate for the intended occupancy, ADA-compliant common restrooms, code-compliant egress and life safety — you will end up paying for base building deficiencies out of your own allowance. Specify delivery condition in writing with a punch list, and specify remedies if delivery is late.

Ignoring the schedule. Delay is expensive in ways that do not appear in the construction budget: holding over at your existing space at penalty rent (often 150 to 200 percent of base rate), double rent, and lost productivity. Negotiate rent commencement to be tied to substantial completion or certificate of occupancy, not a fixed calendar date. If the landlord controls construction and misses the date, you should not be paying rent on a space you cannot occupy. Landlord-delay provisions with day-for-day rent abatement are standard and worth insisting on.

Underestimating permitting. Municipal permit timelines vary from a few weeks to many months depending on jurisdiction and scope. Any change of use, occupancy classification change, or significant mechanical work extends review. Build permitting duration into your schedule realistically, and consider hiring a permit expediter in jurisdictions with known backlogs.

Failing to document change orders in real time. If you intend to request additional allowance for landlord-caused scope changes, you need a contemporaneous log: date, description, cause, cost, and who directed it. Reconstructing this after the fact, months later, is unconvincing and usually unsuccessful.

Overbuilding for a headcount plan that will not hold. Space needs shift, and hybrid work patterns have made historical density assumptions unreliable in many organizations. Building out fifty offices for a plan that never materializes wastes allowance and locks you into a layout you will pay to change. Design for reconfigurability — demountable partitions, generous power and data distribution, open-plan cores — rather than for a specific org chart.

A negotiation checklist and the sequence to run it in

Treat the request as a small campaign with a clear sequence rather than a single conversation. The order matters, because each step either builds leverage or reveals that you do not have any.

Step one: establish your walk-away alternative. Tour two or three genuinely viable competing spaces and get real proposals. This is not theater — you need actual alternatives, because experienced leasing agents can tell the difference between a tenant with options and one performing having them. Your alternative is your leverage, and everything downstream depends on it.

Step two: gather comparable deal data. Ask your broker for recent transactions in the submarket: allowance per square foot, free rent months, term length, and base rate. You want three to five comps in similar building class and size range.

Step three: produce a priced test fit. An architect's layout with a contractor's budgetary estimate turns your request from an assertion into evidence. This costs money and time but changes the entire character of the conversation.

Step four: quantify the gap and the ask. Know your number precisely. "We need $18 more per square foot based on this bid" is a negotiation. "Can you do better on TI?" is a request to be declined.

Step five: identify what you will trade. Decide in advance whether you will pay for the increase with term, rent, amortization, or flexibility, and know your reservation price on each.

Step six: make the ask in writing through your broker, with the comps and the priced test fit attached. Written requests get circulated to the decision-maker; verbal ones get filtered.

Step seven: hold a deadline. Requests without dates drift. Give a decision date tied to a real constraint — a competing proposal expiring, a board approval meeting, a required occupancy date.

One final sequencing note. Whatever you win must land in the work letter exhibit with specific language covering the dollar amount, eligible cost categories, disbursement schedule, documentation required for draws, treatment of unused funds, and the deadline by which the allowance must be claimed. Allowances with short claim deadlines expire — if construction slips past the deadline, the money can simply evaporate. Negotiate a claim window that accounts for realistic permitting and construction duration plus buffer, and tie the clock to delivery of the space rather than lease execution.

Related questions

Can I request a TI allowance increase in the middle of a lease term?

You can ask, but without a triggering event the answer is usually no. Mid-term increases succeed when tied to an expansion, an early renewal extension, a landlord-caused scope change, or a building event that increases the landlord's motivation to retain you.

Is a higher allowance better than free rent?

It depends on your capital position. Allowance is capital you would otherwise spend; free rent is operating cash. If your buildout is expensive relative to rent, prioritize allowance. If your space is largely move-in ready, free rent is usually worth more.

What happens to allowance money I don't spend?

In most standard work letters, the landlord keeps it. Negotiate conversion of unused funds to a rent credit, even at partial value. Also negotiate a realistic claim deadline — unclaimed allowance frequently expires if construction runs past a fixed date.

Should I use the landlord's preferred general contractor?

Not without competitive tension. Push for the right to bid at least three qualified GCs including one of your choosing. Competitive bidding on identical drawings often produces savings comparable to the allowance increase you were seeking.

How much contingency should I carry on a buildout?

Roughly 10 to 15 percent for second-generation space with visible infrastructure, and 15 to 20 percent for shell space or older buildings with unknown conditions behind the walls. Older properties carry additional hazardous-material discovery risk.

FAQ

How far in advance of lease expiration should I start renewal negotiations?

For smaller spaces, roughly 9 to 12 months out. For larger requirements or anything needing significant construction, 12 to 24 months. You need enough runway to tour alternatives, produce a test fit, negotiate, permit, and build before your current lease ends. Starting late destroys your leverage because the landlord knows you have run out of time to leave.

Does asking for more allowance risk the landlord walking away from the deal?

Rarely, if the request is reasonable and supported. Landlords expect negotiation on concessions. What damages deals is not the ask itself but a pattern of repeated escalating requests after terms appear settled. Bundle your asks into a single well-documented request rather than dripping them out over weeks.

Can I get the landlord to fund furniture, cabling, and AV?

Sometimes, though it is usually an exclusion in the standard work letter. Expanding eligible cost categories is often an easier win than increasing the headline number, because it does not change the number the asset manager reports. Ask for it explicitly as a separate item rather than assuming coverage.

What is amortized additional allowance and should I take it?

It is landlord-funded improvement money repaid through increased rent at a stated interest rate over the lease term — effectively a loan. Take it when your own cost of capital is higher than the rate offered, or when preserving cash matters more than total cost. Compare the effective rate honestly against your alternatives.

How do I prove a scope change was the landlord's fault?

Contemporaneous documentation. Keep a change order log recording date, description, who directed the change, the underlying cause, and the cost impact. Landlord-caused items include base building deficiencies, building engineer requirements, and standards imposed after drawings were approved. Reconstructed documentation is far less persuasive.

Does building class affect what allowance I can expect?

Substantially. Class A properties in strong submarkets generally offer richer concession packages because rents and net effective economics support them. Older Class B and C properties may offer less allowance but lower base rent, and often come in second-generation condition, which reduces the buildout cost you need to fund in the first place.
