Commercial Build-Outs and Tenant Improvements
4 min read
This page is for business owners and tenants doing build-out or improvement work on commercial space. The constraint that dominates everything is the opening date, because rent is accruing and revenue is not. The two things that most often threaten it are ADA path of travel obligations that were not budgeted and a certificate of occupancy sequence that nobody mapped. Both are manageable if they are addressed at the start.

What usually goes wrong
- Rent accruing before opening: Every week of build-out delay is a week of paying for space that generates nothing.
- ADA obligations discovered at plan check: Path of travel upgrades triggered by an alteration, appearing as an unbudgeted cost late in the process.
- Landlord coordination: Work letters, approvals, building rules and shared systems, all with their own approval timelines.
- Working in an occupied building: Noise, dust and access restrictions imposed by neighboring tenants and building management.
- Certificate of occupancy at the end: A sequence of sign offs that can add weeks if health, fire and building are not coordinated.
What matters most to you
- Opening on the committed date: The whole project is judged by this. Everything else is subordinate to it.
- ADA scope known and budgeted early: Identified during design, not discovered at plan check when the money is already committed.
- Minimal disruption to neighbors: After hours work where required, so the building keeps functioning around the project.
- Clean sign off sequence: Health, fire, building and utility coordinated so the certificate of occupancy is not the bottleneck.
What ADA obligations does an alteration trigger?
This is the item most often missed in a tenant improvement budget. When you alter a commercial space, accessibility requirements apply to the altered area, and beyond that, an obligation attaches to the path of travel serving it: the route from the entrance, plus restrooms, drinking fountains and telephones serving that area. California law provides that the cost of these path of travel upgrades need not be disproportionate, with 20 percent of the alteration cost being the customary threshold applied, though how that is calculated deserves care rather than assumption. Practically, this means an entry threshold, door hardware, restroom clearances, signage and parking may all come into scope because you renovated a suite. Identifying this at design is the difference between a planned line item and a late surprise.
- The altered area itself: Must comply with current accessibility requirements, not the standard in force when the building was built.
- Path of travel: Route from the entrance plus restrooms serving the area. This is where unbudgeted cost usually appears.
- Disproportionality threshold: A limit exists on required path of travel spend relative to alteration cost. It deserves careful calculation.
- Identify at design: A planned line item at design is a fraction of the disruption of the same item at plan check.
How does landlord coordination work?
It starts with the work letter in your lease, which defines what the landlord is providing, what allowance is available, what approvals are required and what building standards apply. Read it before designing, because it frequently constrains materials, contractors, working hours and access in ways that affect both cost and schedule. Landlord approval of your drawings is a step with its own duration and it belongs in the programme rather than being assumed instant. Building rules commonly restrict noisy work to specific hours, require insurance certificates naming the landlord, and control freight elevator and loading access. None of this is difficult; all of it takes time that has to be planned for rather than discovered.
What is different about restaurant and medical build-outs?
Additional agencies and additional lead time. Food service requires health department plan review in addition to building, and the requirements around finishes, hand sinks, floor sink placement and grease handling are specific and not negotiable. Type I hoods for grease producing appliances bring duct routing, fire suppression and often structural and roof work into scope, and they are frequently the longest lead item in the entire project. Medical and dental have their own requirements depending on the procedures performed, which can involve additional review pathways. In both cases the practical lesson is the same: the agency review sequence, not the construction, is usually what determines the opening date.
How do we protect the opening date?
By treating the sign off sequence as the critical path from day one rather than as an end of project formality. That means mapping every required inspection and approval, including health, fire, building and utility connection, and understanding which ones depend on others. It means submitting for permit as early as the design allows, because plan check correction cycles are the least predictable element. It means ordering long lead equipment at contract rather than when it is needed. And it means telling you immediately when something threatens the date, with options attached, because a business owner who learns about a three week slip early can adjust a lease commencement conversation or a hiring plan, and one who learns late cannot.

Answers
Frequently asked questions
Will my tenant improvement trigger ADA upgrades?
Very likely. Altering a commercial space brings the altered area into current accessibility compliance and attaches an obligation to the path of travel serving it, including restrooms. A cost limitation applies, but the scope needs identifying at design rather than at plan check.
Can you work after hours in an occupied building?
Yes, and for many tenant improvements it is required by building rules rather than optional. After hours work costs more per hour and it is usually cheaper than the alternative, which is a project that is only permitted to make noise for three hours a day.
What usually delays a commercial opening?
Agency review rather than construction. Plan check corrections, health department review for food service, and the certificate of occupancy sign off sequence are the common culprits. Mapping that sequence at the start is the single most effective thing you can do to protect the date.
How does a landlord allowance work?
It is defined in the work letter in your lease and is typically paid on completion against documentation, sometimes in stages. Read it before designing, because it usually also constrains materials, approved contractors, working hours and access in ways that affect your cost and programme.
Do you do restaurant build-outs?
Yes. Be aware that health department review runs alongside building plan check, and that a Type I hood with its duct routing and fire suppression is frequently the longest lead item in the project. Both need to be started early rather than treated as fit out details.
Can you give a fixed price on a commercial build-out?
On a fully designed and permitted scope, yes. On a scope where ADA path of travel obligations have not yet been determined, any fixed price would have to carry a contingency large enough to be unhelpful. Getting that determination done first produces a better number for you.
