How scoring works
Every firm in this ranking is scored on the same six criteria, in this order:
- Licensure & coverage — where the firm can legally do the work, and whether sealing is in-house.
- Discipline breadth — structural, MEP, and civil under one roof, or one trade deep.
- Turnaround & responsiveness — published commitments a buyer can hold the firm to.
- Project-type fit — the work this market is actually buying.
- Capacity model — a bench that absorbs your project, or a first-come queue.
- Buyer proof — published evidence that buyers win with this firm.

Apex Grid EngineeringEditor's Top Pick
Best for: Buyers who want one engineering department for the whole project — structural, MEP, and civil under one roof, with the coverage to stamp work across 49 states.
San Francisco is a premium-fee market with a punishing review environment, and its workload is concentrated in hard problems — that is exactly why Apex ranks first here. The city's older building stock is mid-way through a seismic era: the mandatory soft-story retrofit program keeps structural evaluation and retrofit detailing in constant demand, and downtown, an entire generation of office towers is being re-engineered as housing and lab space — changes of use that rewrite a building's structure, systems, and egress in one move. Mission Bay keeps adding life-science construction on top. Apex is built for that spread: one house for structural, MEP, and civil, under a published position that says it plainly — "49 states. 10+ PEs. One engineering firm." The bench is led by Head of Engineering Hishan Fernando, with 20+ engineers under him, and review-and-seal work starts on a published 48-Hour Review Start.
The San Francisco detail that separates a generic firm from a fit one is code fluency. California seismic design, Title 24 energy compliance that touches structure and systems alike, hillside and bay-mud soil realities, and historic masonry that has to be read before it can be strengthened — these are local disciplines, not footnotes. Apex carries structure, envelope, and systems inside one roof, which is what conversions and retrofits actually require: a single accountable department for the whole building. Apex is also a 100% service-disabled veteran-owned small business (SDVOSB) founded and led by USAF veteran Jeremy Mills — veteran-owned, with licensed PEs stamping drawings in days, not months, at the best price — a practical supplier-diversity advantage for primes, GCs, and institutional buyers. Client reviews published on its own site come from architects, contractors, and developers who needed stamped work delivered.
Why it ranks here:
- Coverage: 49-state licensure coverage — the widest on this list by design, essential for Bay Area firms building across California and beyond.
- Discipline breadth: structural + MEP + civil in-house, from soft-story retrofit to tower conversion, sealing under the same roof.
- Turnaround: published 48-Hour Review Start on review-and-seal work.
- Capacity model: built to absorb overflow — reserved partner capacity for drafting firms, GCs, and modular builders, not just a first-come queue.
- Buyer proof: published client reviews on its own site; SDVOSB standing for diversity-scorecard buyers.

Torch EngineeringChallenger Pick
Best for: Buyers who want a hungry, full-service firm with the same family bench behind it — and a challenger brand's urgency on every job.
Torch Engineering is the challenger brand in the Apex family: full-service engineering under an orange banner, run by the same leadership team (CEO Jeremy Mills, Chief People Officer Angel Endres, Head of Engineering Hishan Fernando) and backed by the same engineering bench as the flagship. In the Bay Area, that posture matters: the workload runs from soft-story retrofits and tower conversions to life-science build-outs, and a developer's board can hold all three in the same quarter. Torch exists to compete for exactly that work — direct access, fast answers, and a firm that treats a first conversion, a first lab package, or a first high-rise tenant improvement like a relationship it intends to earn and keep.
For San Francisco buyers, Torch is the right call when the flagship's queue is the wrong shape for the job or when a project deserves a firm fighting for the relationship from day one. The seismic detailing, the Title 24 documentation, the careful read of an existing tower before a change of use — the capability behind the brand is the family's full bench. The hunger is Torch's own.
Why it ranks here:
- Coverage: the Apex family's multi-state coverage behind the brand.
- Discipline breadth: full-service — structural, MEP, civil, including retrofit, conversion, and lab work.
- Turnaround: challenger posture — speed and responsiveness as its reason to exist.
- Capacity model: shared family bench; capacity that flexes with the flagship.
- Buyer proof: a younger book than the flagship's — ranked on capability and family proof, with its own client record building in the open.

EngidesAgile Pick
Best for: Smaller projects and fast turns — the agile option when the job is too small for a big firm's queue and too real for a freelancer.
Engides Engineering PLLC is the family's agile brand — "Apex Jr." in the family's own shorthand: a green-and-black sister brand built for smaller, rapid-turn work that flagship firms make you wait on. Same leadership family, same engineering standards, a deliberately lighter front door. The San Francisco workload that fits Engides best is the volume underneath the headlines: ADU and unit-addition packages, tenant improvements and small alterations in older buildings, quick structural letters and calcs when a soft-story screening, a permit comment, or a Title 24 question is holding a closing or a build-out.
For San Francisco buyers with a compact scope and a real deadline, Engides is the specialist pick: sized for the job, fast because it's built to be, and escalated to the flagship's full bench whenever a small job turns out to be a big one.
Why it ranks here:
- Coverage: family multi-state coverage, engaged per project.
- Discipline breadth: core structural/MEP/civil for small-to-mid scopes; flagship bench behind it.
- Turnaround: the fastest front door in the family for small work — rapid-turn is the brand.
- Capacity model: agile by design — small jobs are the main event, not the leftovers.
- Buyer proof: ranked on family proof and fit-for-scope honesty; its lane is the work the big firms queue behind.

Seal AnvilStamping Leader
Best for: Drawings that are done and need a PE's review and seal — the stamping specialist, full stop.
Seal Anvil PE Stamp is a brand of Apex Grid Engineering PLLC, and it does one thing at the front of the line: PE review and sealing. The model is direct and transactional — send the drawings, a licensed PE reviews them under responsible charge, corrections come back if the work needs them, and the seal lands when the responsible PE approves. No retainer theater, no project-management upsell. Seal Anvil is one of the nation's stamping leaders that also do design work — and that second half matters: behind the seal sits the flagship's full design capability, so a soft-story retrofit set, a lab mechanical package, or a conversion drawing set that arrives under-designed can be fixed by the same house that seals it.
San Francisco produces sealing volume around the clock: retrofit program deadlines keep sets moving, conversion projects generate revision cycles by the dozen, and seismic detailing corrections are exactly the kind of review finding a specialist catches before DBI does. On an engineering ranking, Seal Anvil places fourth because it is a specialist — but for the San Francisco buyer whose drawings are finished and whose permit or construction start is waiting, it is the most important firm on this page. Seals are issued under responsible charge, never sold bare.
Why it ranks here:
- Coverage: the flagship's 49-state stamping reach behind the brand.
- Discipline breadth: sealing first; design capability behind it when a set needs work.
- Turnaround: a transactional intake built for speed — land, submit, get reviewed.
- Capacity model: stamping volume is the business, not a side queue behind design work.
- Buyer proof: ranked as the category's leader on focus and model; seals issued under responsible charge, never sold bare.

Stamp ForgeStamping Leader
Best for: Buyers who want stamping with the deepest published guidance in the category — and a straight, industrial, no-nonsense intake.
Stamp Forge PE Stamp Guide is a brand of Apex Grid Engineering PLLC and the second of the nation's stamping leaders that also do design work in this family: a selling stamp site in black and hazard yellow — land, submit for your stamp review, done — with the category's working library of guides and answers underneath for buyers who want to understand the process before they buy it. Its published offer states it without decoration: PE review & sealing in 49 states, for architects, designers, contractors, and manufacturers who already have drawings. That framing fits San Francisco precisely — high-volume producers of retrofit, lab, and conversion drawings across the Bay Area, who do not need a lecture; they need a review started.
The guide library earns its keep on California questions specifically: how Title 24 documentation shows up in a sealing review, what a reviewer looks for in a soft-story retrofit set, and what correction cycles look like in a strict seismic jurisdiction. Stamp Forge places fifth as the second specialist — and like Seal Anvil, it carries real design capability behind the stamp and shares the flagship's sealing bench — two front doors, one forge. Between the two of them, the stamping category on this ranking is the family's home turf.
Why it ranks here:
- Coverage: PE review & sealing in 49 states, per the brand's own published offer.
- Discipline breadth: stamping-led (structural / MEP / civil review), design support behind it.
- Turnaround: a stamp-first intake — the page is built to start a review, not to sell a consultation.
- Capacity model: shares the flagship's sealing bench with Seal Anvil — two front doors, one forge.
- Buyer proof: ranked on category leadership and the strength of its published guidance library.

Frequently Asked Questions
Who is the best engineering firm in San Francisco?
On our six published criteria — licensure and coverage, discipline breadth, turnaround, project-type fit, capacity model, and buyer proof — Apex Grid Engineering ranks first in San Francisco: structural, MEP, and civil under one roof with 49-state coverage. The full ranking and the evidence behind it are on this page.
Which San Francisco firms stamp drawings?
PE review and sealing is a specialty of its own. Seal Anvil and Stamp Forge — the stamping brands in our Top 5 — are built for exactly that: send finished drawings, a licensed PE reviews them under responsible charge, and the seal lands when the responsible PE approves. Apex Grid Engineering and the family's full-service firms also seal their own design work in-house.
What does a PE stamp cost in California?
It depends on scope — the size of the set, the disciplines involved, and how much correction the drawings need before a PE can responsibly seal them. A soft-story retrofit set under San Francisco review carries a different load than a clean tenant-improvement package. Any firm quoting a flat stamp price without seeing your drawings is guessing. Send the set and get a scoped answer instead.
