Tenant Improvements Requirements: Who Sets Them
Tenant improvements requirements come from the landlord, municipality, insurer, and lender, with paperwork and approvals unfolding at different stages.
Nobody refuses a fit-out outright. What happens instead is that the work stalls, one document at a time, while the rent runs. This page lists what you will be asked to produce, who asks for it, and the order the requests arrive in.
Tenant improvements requirements come from three separate parties. The landlord protects the building, the municipality protects the public, and your insurer and lender protect themselves.
What to take away
- Three parties set requirements, and each has its own list, its own timetable and its own idea of what counts as complete.
- Most delays are documentary rather than physicalan insurance certificate with the wrong named party stops a job as effectively as a missing wall.
- Ask for every list in writing before the lease is signed, because after signing you have no way to simplify any of them.
What the landlord requires
The landlord's requirements are contractual, which means they are negotiable while the lease is in draft and fixed afterwards.
Landlord approval requirements
- Drawings for design and construction approval
- Contractor the landlord will accept
- Insurance certificates for you and trades
- Schedule and working hours
- Evidence of payment and lien waivers
- Closeout documents and sign-off certificates
The allowance mechanics behind that last group, and why the money arrives late, are set out in tenant improvements.
The work letter usually covers six items.
- Delivery condition.The condition of the shell, the base building electrical and mechanical capacity, the sprinkler layout, the ceiling grid, and who removes the last tenant's improvements.
- Approved contractor list.Which trades you must hire from the landlord's list, usually sprinkler, fire alarm, HVAC controls and electrical service, because a fault in any of them reaches other tenants.
- Insurance limits.What your contractor carries and what you carry: general liability per occurrence and in aggregate, workers' compensation, builder's risk, the landlord named as additional insured, and a waiver of subrogation.
- Hours.When work may happen, which windows are reserved for noisy trades, and how freight elevator use and after-hours access are booked.
- Plans.What you submit, who pays the landlord's reviewer, how long the landlord has to respond, and whether silence counts as approval.
- Closeout documents.As-built drawings, the final permit sign-off, warranties, maintenance manuals, lien waivers, and proof that contractors were paid.
Allowances are quoted per rentable square foot and vary with building class, market and lease term. Every published figure is deal specific, so confirm the amount, the triggers and the deadline in the work letter.
What the municipality requires
This list is local, and the only reliable source for it is the office that issues the permit. What is broadly common is the shape.
Municipal permit sequence
- Confirm the use is allowed at the address
- Submit permit application with stamped drawings
- Undergo review by building, fire, accessibility desks
- Pass inspections at defined stages
- Obtain final sign-off before occupation
- A permit application with drawings stamped by whoever local rules require to stamp them.
- Evidence that the use itself is allowed at the address before anyone reviews the construction. Finding that out is the subject of zoning and permits.
- Review by more than one deskbuilding, fire, accessibility, health where food is involved, and sometimes a utility or a transport authority.
- Inspections at defined stages, most of which happen before the work they inspect is covered up.
- A final sign-off before the space may be occupied. The general idea behind that document is described in the entry on the certificate of occupancy, though the name and the process differ by jurisdiction.
A typical alteration package holds the application form, a stamped architectural set with demolition, floor, ceiling and finish plans, and a life safety plan. It also carries an electrical and plumbing set, a sprinkler and alarm plan, and the contractor's insurance certificate.
Review runs in rounds. Zoning or use confirmation comes first. Comments from the building, fire and accessibility desks go back to the designer, who resubmits until the desks clear. Review time follows the office's backlog, not the code.
Inspections track the work. Footings and slab come before the pour, in-wall electrical, plumbing and mechanical before the walls close. Firestopping, a sprinkler hydrostatic test, a fire alarm test and a final inspection come later.

Two rule sets sit behind almost every review. Construction rules come from a model code adopted and amended by a state or municipality, published in the I-Codes library.
Accessibility rules for public spaces come from a separate federal standard, explained for small businesses in the ADA primer. Neither is optional and neither is automatically satisfied by the other.
What your own side requires
- Insurance.Your insurer will want to know what is being built and by whom, and may have conditions of its own about hot works, sprinkler shutdowns and security during construction.
- Finance.A lender funding the fit-out will want the drawings, the contract, the schedule of values and evidence that the landlord's contribution is committed.
- Your lawyer.A property lawyer reads the work letter alongside the lease, because the two documents allocate the same risks in different words and the conflict is usually resolved against the tenant.
The order things happen in
| Stage | Who asks | What you produce |
|---|---|---|
| Before the letter of intent | You | A brief describing the space you need built |
| Before the lease is signed | Landlord | Agreed delivery condition, work letter, approval timetable |
| Before design starts | Landlord | Appointed designer, base building information request |
| Before permit application | Municipality | Stamped drawings, use confirmation, application forms |
| Before work starts | Landlord and insurer | Insurance certificates, contractor details, schedule, method statements |
| During the work | Municipality | Inspections at defined stages |
| Before the contribution is paid | Landlord | Invoices, lien waivers, evidence of completion |
| Before occupation | Municipality | Final sign-off, then the landlord's own closeout list |
| Before the end of the term | Landlord | Restoration scope, method and any cash allowance agreed in the work letter |
The requirements people forget
Some obligations sit outside the construction contract entirely and surface late.
Requirements people forget
- Ventilation and air handling for your layout
- Fire strategy review for new walls and doors
- Data and telephone cabling lead time
- Restoration obligations settled in writing
- Ventilation and air handling have to serve the layout you built, not the one the base building assumed. The reference standard for outdoor air rates is ASHRAE 62.1, and a designer will tell you whether your plan changes what the system has to deliver.
- Anything that changes the fire strategy, including new walls, new doors and new storage arrangements, has to be reviewed against the life safety requirements the building was approved under.
- Data and telephone cabling is frequently outside the base contract and outside the landlord's contribution, and it has its own lead time.
- Restoration at the end of the term is a requirement created on the day you build. Settle in writing what comes out and what stays.
Getting the lists early
Ask for all three lists before the lease is signed, in one email each, and keep the replies. A landlord who will not describe the approval process in writing is telling you something about how the process will run. The same request to the permit office costs nothing and often reveals a review step nobody mentioned.
If you are fitting out a floor, the base building questions worth asking first are in office space. If the work sits inside a trading unit, the approval sequence is tighter and the ordering rules in retail space apply on top of everything here.
Common questions
Can the landlord reasonably refuse my contractor?
That depends entirely on what the lease says, which is why the standard for objection belongs in the draft. A clause allowing refusal without a stated reason is a clause that can stop your job for any reason.
Do I need permits for cosmetic work?
Sometimes not, and the line is local. Painting and carpet usually sit below the threshold. Anything touching walls, doors, ceilings, power, water or the fire systems usually does not. Ask the permit office rather than the contractor.
Who is responsible if the drawings fail review?
Whoever produced them, under whatever contract you signed with them. This is worth reading before you appoint a designer, because a redesign at your cost also spends time you are paying rent for.
Is a second-generation space simpler?
The construction usually is. The paperwork can be worse, because you inherit whatever the last tenant built without a permit, and the review that uncovers it lands on you.
