Houston permit notes
City of Houston permits route through Houston Public Works Code Enforcement. Plan reviewers commonly comment on duct route and 506.3 grease duct enclosures; we draw to head off the typical second-round.
Frequently asked questions
Does Pyra Engineering design fire alarm or sprinkler systems?
No. Fire alarm system design and installation is the fire alarm vendor's scope. Sprinkler design is the fire-protection contractor / FPE scope. Pyra Engineering's scope is mechanical, electrical, and plumbing (MEP) only — we coordinate locations and conduit notes for FA/sprinkler tie-ins on our drawings, but we do not stamp those designs.
Do I need a sealed Texas engineer for a office tenant fit-out project in Houston?
For most offices of any meaningful size, yes. Texas Occupations Code §1001 requires MEP designs above certain thresholds to be stamped by a licensed Texas Professional Engineer. Drawings without a TX seal can stall plan review or trigger code-enforcement action. Pyra Engineering is a Texas-licensed firm; the drawings we deliver are stamped and ready for Houston permit submittal.
What's typical turnaround on MEP drawings for a office tenant fit-out in Houston?
Standard office tenant fit-out fit-outs run 2–4 weeks from kickoff to permit-ready package, depending on scope and how quickly architectural backgrounds settle. Fast-track schedules are doable when we surface the deadline at quote — we have a separate workflow for franchise-rollout pace and developer-deadline pressure.
Will Pyra Engineering stamp drawings done by a contractor or designer?
We perform an engineer-of-record review before stamping any third-party drawings. If the design is sound, we mark up the corrections needed and stamp once they're incorporated. If it isn't, we'll tell you up front rather than stamp something we don't stand behind. Stamping fees are scoped to the review effort.
Does the MBE/HUB certification benefit me on a Houston project?
Yes if you're tracking diversity-spend goals on public-sector or large corporate projects. Pyra Engineering's HUB and MBE certifications count toward those goals; many City of Houston, county, and Fortune-500 supplier-diversity programs accept them. Bringing us in lets you both meet the goal and get the engineering.
How does Pyra Engineering quote offices MEP design?
Fixed fee based on conditioned area, scope (full MEP vs. discipline-specific), and project type (shell, TI, or ground-up). Quotes typically come back within one business day of receiving the architectural set or a one-paragraph scope summary. No estimates without scope — we don't do range pricing that creeps.
What's the most common reason TX office fit-outs slip schedule?
Per our Q2 2026 survey of TX commercial fit-outs, 68% slip 2+ weeks from MEP-coordination causes. Top driver: shell-system mismatch — chilled-water capacity, condensate routes, panel space — all decided before the tenant arrives. We shell-review every TI before fee.
What landlord info do you need before I can ask for a TI fee?
Best three: chilled-water riser availability and capacity at the floor, the landlord panel schedule (or where they'll land your service), and the smoke-control / fire-alarm head-end status. With those, we fee accurately.
What if the landlord shell can't support our load?
Three options: (1) supplemental DX or VRF for the tenant zone, (2) splitting the floor into two HVAC zones with different setpoints, (3) negotiating with the landlord for shell upgrade. We tell you which is cleanest at shell review.
Do you handle the COMcheck for office TIs?
Yes — every TI submittal includes COMcheck (envelope, lighting, mechanical) plus the IECC 2021 / ASHRAE 90.1-2019 documentation Houston reviewers expect. We do energy modeling when threshold projects require it.
Can MEP be engaged at SD or is CD too late?
SD is cheapest. By CD the tenant criteria, equipment, and finishes are locked — every late MEP change is a rework. We do flat-rate SD-phase reviews specifically so MEP risk surfaces before the tenant signs off.
How is outdoor air sized for office?
ASHRAE 62.1 Table 6.1: 5 cfm/person + 0.06 cfm/sf for office. Conference rooms and reception get higher per-person rates. We tag every space and sum to design OA.
Do you do VAV or fan-coil zoning?
Both. VAV serving from a central AHU is most common for larger TIs. Fan coils are used when serving from a chilled-water plant with limited duct space. We pick based on shell.
How many panel circuits per workstation?
Typically 1 dedicated 20A per 3 workstations + general lighting + receptacle on shared circuits. We model load per NEC 220 with realistic diversity.
Do you spec lighting fixtures or just calc loads?
Both. We provide a lighting package (LED specs, fixture types, control strategy) plus the photometric calc. Architect can swap fixtures within the budget envelope.
What about IT closet cooling?
Dedicated split-DX or supplemental fan-coil sized for the IT load (typical 1.5–3 ton for a small comm closet). We coordinate location with low-voltage.
Daylight harvesting and occupancy sensors — required?
Per IECC 2021 §C405. Daylight harvesting required in regularly occupied daylit zones. Occupancy sensors required in most enclosed spaces. We include both in the lighting package.
Fire alarm modifications — your scope?
No — fire alarm is not in our scope. The fire alarm vendor designs and installs all FA work (tenant device additions, head-end tie-in, programming, testing). We coordinate locations on our drawings but do not stamp FA design.
Do you handle break room / pantry MEP?
Yes — exhaust hood (Type II usually), water/drain for sink, dishwasher rough-in, microwave/coffee circuits. Standard scope on office TI.
What's the typical permit cycle for office TI in Houston?
1–2 cycles is standard. Common second-round comments target energy code (COMcheck), accessible restroom layout, and emergency egress lighting circuits. We pre-empt all three on the first submittal.
Do you spec emergency egress lighting?
Yes — per NFPA 101 minimum illumination at egress paths, with battery backup or generator-fed. We design and circuit, owner/EC selects fixtures from our spec.
How do you handle conference room AV power?
Dedicated isolated-ground circuit for the AV rack, table-top floor boxes for laptop power, and ceiling-power for projectors/displays. All on our drawings.
What's typical fee compared to a full-service A&E?
We're 30–50% lower than multi-discipline A&E firms because we don't carry their overhead. Same stamp, faster turnaround on the MEP side.
Do you do construction administration?
Yes — CA scope includes RFI response, shop-drawing review, site visits, and punch-list. Typical CA fee is 15–20% of design fee for office TI.
Will you stamp drawings done by the tenant's preferred consultant?
We perform an engineer-of-record review first. If the design is sound, we mark up corrections and stamp. If not, we tell you up front.
How do you handle landlord vs tenant utility separation?
Submetering recommended for large TIs (over ~5,000 sf). We design separate meter banks for tenant electrical, gas, and water if the lease calls for it.
Open: Texas Tenant Fit-Out MEP Schedule Risk Survey (Q2 2026)
We’re surveying 100+ Texas GCs, architects, and developers on what actually breaks tenant fit-out MEP schedules — and what predicts the projects that stay on time. If you’ve shipped two or more TX commercial fit-outs in the last 12 months, your data would help.
