If the City of Austin has issued MEP comments on your commercial plan review, the person who can actually clear them is the Texas-licensed professional engineer who sealed the drawings. A permit expediter can carry the paperwork and chase the calendar. Only a P.E. can revise and re-seal a mechanical, electrical or plumbing sheet. That distinction is the whole reason a comment cycle stalls: the person managing the submittal is usually not the person who can answer the comment.
What Austin actually sends you
Austin’s Development Services Department consolidates commercial plan review comments into a Master Comment Report – every reviewer, every discipline, one document. It is not a courtesy summary. It is the working file for your resubmittal, and DSD expects it back.
As DSD currently publishes the update process, a resubmittal has three parts:
- the Master Comment Report itself,
- a written response to each comment, and
- the complete updated plan set – not just the sheets you changed.
Sending only the revised sheets is the most common way an update comes back untouched. It is an administrative failure, not a technical one, and it costs a full cycle.
The Austin-specific trap: MEP permits are separate
In Austin the mechanical, electrical and plumbing trade permits are issued separately from the commercial building permit. The building plans still have to show coordination with the MEP systems, and reviewers flag anything that leaves it ambiguous how the MEP work will be permitted. Teams that have only worked in cities where MEP rides inside the building permit tend to under-document that coordination, and then read the resulting comments as arbitrary. They are not arbitrary – they are asking a question the drawing set never answered.
How to answer a comment so it closes on the first pass
A comment closes when the response contains the evidence, not a commitment to produce it. In practice that means:
- Answer in the reviewer’s vocabulary. If the comment cites a code section, the response cites the same section and shows compliance against it.
- Attach the calculation. Ventilation rates, load calculations, fixture counts, panel schedules – a number in a narrative response is an assertion; the calculation behind it is an answer.
- Respond to every comment, including the ones you think are wrong. A disagreement documented with a code basis is a valid response. A skipped comment is an open comment.
- Do not renumber or reorganise the report. The reviewer reads down their own list.
If a comment genuinely needs a conversation, DSD’s published practice is that the assigned reviewer responds to an email or call within one business day. When the discussion will run longer than about twenty minutes, or involves more than one review discipline, DSD asks you to book a Plan Review Consultation rather than handle it informally. Booking that meeting early is almost always cheaper than a second rejected update.
Where MEP comments come from on a finish-out
Across our project library the same four scopes generate most of the MEP comment volume on Texas commercial finish-outs:
- Ventilation and exhaust – outdoor-air rates against the occupancy actually being built, and exhaust for restrooms, kitchens and any process load.
- Electrical service and panel capacity – whether the existing service supports the new load, and whether the panel schedule reflects what is being added.
- Plumbing fixture counts and waste – fixture counts driven by the occupancy classification, and grease waste where food service is involved.
- Occupancy classification changes – the quiet one. A change of occupancy can move ventilation, exhaust, fixture counts and egress-related mechanical requirements all at once, and a set drawn against the old classification generates comments in every discipline.
If you are the building owner
On a vacant-suite, demising or change-of-occupancy project, the reviewer’s questions are usually about the base building – existing service size, available panel capacity, rooftop unit inventory, meter arrangement, how water and gas are separated between suites. Those are facts the owner holds, not the tenant. When an owner brings in their own MEP engineer, the comments get answered by the party who actually has the information, and the tenant’s contractor stops being a relay.
This is also why suite splits generate longer comment lists than straight finish-outs. Dividing one suite into three forces four decisions at once – electrical service division and metering, rooftop HVAC zoning to the new suite lines, water and gas separation, and whether the new occupancy changes ventilation and fixture counts. Made deliberately before the first submittal, they are four line items. Discovered in a Master Comment Report, they are a redesign.
Taking over a set someone else sealed
It happens: the original engineer is unresponsive, the architect has moved on, or the set was drawn out of state. A different Texas-licensed P.E. can take over the MEP scope – review the existing set, decide what is defensible, revise what is not, and seal the sheets they revise. What no one can do is seal someone else’s unreviewed work. Expect a review step before the resubmittal, and budget for it.

Frequently asked questions
Who can clear MEP permit review comments on a City of Austin commercial project?
The Texas-licensed professional engineer who sealed the MEP drawings. A permit expediter can manage the submittal and the calendar, but only a P.E. can revise and re-seal mechanical, electrical or plumbing sheets. If your original engineer is unresponsive or off the job, a different Texas P.E. can take over the MEP scope, review the existing set, and re-seal the sheets they revise.
What is a Master Comment Report in Austin?
It is the consolidated document Austin’s Development Services Department issues after commercial plan review, listing every reviewer’s comments across disciplines in one place. It is the working document for your resubmittal – you correct against it and respond to it, comment by comment.
What do I have to include when I resubmit after Austin MEP comments?
As DSD currently publishes the update process: the Master Comment Report, a written response to each comment, and the complete updated plan set. Sending only the revised sheets is the most common reason an update is bounced back without technical review.
Are MEP permits separate from the building permit in Austin?
Yes. In Austin the mechanical, electrical and plumbing trade permits are issued separately from the commercial building permit. The building plans still have to show coordination with the MEP systems, and reviewers will flag anything that leaves it ambiguous how the MEP work gets permitted.
Can I talk to the reviewer who wrote the comment?
Yes. DSD’s published practice is that the assigned reviewer responds to an email or call within one business day. If the conversation will run past about twenty minutes, or needs more than one review discipline in the room, DSD asks you to schedule a Plan Review Consultation instead of handling it ad hoc.
How long does a resubmittal take to clear?
It depends on the cycle you land in and how clean the response is. The variable you control is the response quality: a comment answered in one pass with the calculation attached usually closes; a comment answered with a promise usually comes back. Confirm current review timelines with Development Services for your specific permit.
I am the landlord, not the tenant. Can I bring in my own engineer to clear the comments?
Yes, and on a vacant-suite or demising project it is often faster. The owner controls the base building information the reviewer is asking about – existing service size, panel capacity, rooftop unit inventory, meter arrangement. An engineer working for the owner can answer those comments directly instead of routing them through a tenant’s contractor.
Does a suite split or change of occupancy make the comments worse?
Usually, yes – because those scopes touch the parts of the building the reviewer scrutinises most: how the electrical service is divided and metered, how rooftop HVAC is zoned to the new suite lines, how water and gas are separated, and whether the new occupancy classification changes ventilation, exhaust or fixture-count requirements. Getting those four decisions right before the first submittal is what keeps the comment list short.
Do you work outside Austin?
Yes. Pyra IXI is a Texas-registered engineering firm (TBPE F-22556) working across Texas commercial construction, and the comment-resolution process differs by city – Austin issues a Master Comment Report, Dallas runs a Q-Team session, San Antonio publishes plan review comments online through its permitting portal, and Houston works through the Permitting Center’s comment letter. The engineering is the same; the paperwork is not.
What does it cost to have an engineer clear permit comments?
It depends on how many comments there are, whether they are answerable from the existing design or require redesign, and whether we sealed the original set. Pyra IXI quotes commercial MEP scopes within one business day.
