Mechanical, electrical, and plumbing engineering from one licensed California team, produced with your Title 24 compliance so every sheet agrees. Flat price up front, corrections answered free until your permit is issued.
Free scope review included. No obligation, no hourly billing.
Mechanical, electrical, and plumbing engineering for commercial and residential projects across San Diego County, produced as one coordinated set instead of three separate consultants who never see each other’s sheets.
Load calculations, equipment selection, ductwork layouts, and ventilation sized for San Diego’s mild coastal climate rather than a generic rule of thumb.
From $2,450
Service and panel sizing, load calculations, power and lighting plans, plus the Title 24 lighting controls documentation plan check expects.
From $2,150
Water, waste, vent, and gas routing with fixture unit calculations, including grease interceptor sizing for food service tenants.
From $1,950
All three disciplines drawn together and clash-checked against the architectural background before the set ever reaches DSD.
From $5,850
Residential and nonresidential energy calculations and forms, produced by the same team that sized your equipment.
From $1,450
Architects, GCs, and design-build firms: MEP production under your brand when your in-house team is at capacity.

San Diego sits mostly in California climate zone 7, one of the mildest in the state, which changes how HVAC should be sized. Cooling loads that would be normal inland are oversized here, and oversized equipment costs your client money twice, once at purchase and again every month in efficiency. We size to the actual zone. We also design around what San Diego plan check reviews closely: Title 24 nonresidential compliance, CALGreen requirements for EV-ready circuits and solar readiness, coastal corrosion on rooftop equipment, and ventilation for restaurant and medical tenants.
Architectural background, existing conditions, and scope. We review free.
One flat price per discipline or for the full coordinated set.
Calculations, layouts, schedules, and Title 24 produced together and clash-checked.
Submit to DSD. We answer plan-check corrections free until approval.
Mechanical, electrical, and plumbing drawn together with structural and Title 24, so sheets agree before submittal.
A flat written proposal before any work starts, priced per discipline or as a full set, never hourly.
Equipment selected for San Diego’s actual climate zone, not oversized from an inland default.
White-label MEP production for architects and design-build firms who need a second team on short notice.
Service areas: San Diego, Kearny Mesa, Sorrento Valley, Mission Valley, Chula Vista, Carlsbad, Escondido, Oceanside, La Jolla, Otay Mesa, and all of San Diego County. See also our MEP design, commercial permit drawings in San Diego, and structural engineer in San Diego.
An MEP set is judged on whether the calculations, the schedules, and the drawn layouts tell the same story. Here is what we deliver, and what plan check actually looks at.
Heating and cooling load calculations by zone, equipment selection and schedules, duct layouts with sizes, diffuser placement, ventilation rates by occupancy, and exhaust for restrooms, kitchens, and any process spaces. Rooftop equipment gets weight and support coordinated with the structural sheets.
Service and panel sizing with load calculations, single-line diagram, panel schedules, power plans, lighting layouts and photometrics where required, and Title 24 lighting control documentation. CALGreen EV-ready circuits and solar-ready provisions are included where the occupancy triggers them.
Water supply sizing by fixture units, waste and vent risers, gas line sizing and routing, water heater selection, and grease interceptor sizing for food service. Backflow prevention and any required point-of-use treatment are shown rather than left to the contractor.
All three disciplines are overlaid on the architectural background and clash-checked before delivery, so ductwork is not running through a beam and a panel is not landing on a door swing. Title 24 is produced by the same team, so the modeled equipment matches the scheduled equipment.
The single most common MEP correction in San Diego is a mismatch between the Title 24 energy model and the mechanical schedule. It happens constantly when the energy consultant and the mechanical engineer are different firms working from different revisions of the same drawing. The reviewer sees a 4-ton unit in the model and a 5-ton unit on the schedule and rejects both. Because we produce the calculations and the drawings together, that mismatch does not exist in the first place. The second most common is ventilation that meets the code minimum on paper but has no documented path back to the outside air source, which we resolve by showing the full route rather than a note.
MEP design from Fast Build runs $1,950 to $9,600 depending on scope and building size. A single discipline on a small tenant improvement, plumbing only for example, sits at the low end; a fully coordinated mechanical, electrical, and plumbing set for a restaurant or medical suite with Title 24 sits at the top. One flat quote up front, never hourly billing.
Mechanical covers HVAC equipment selection, load calculations, ductwork, and ventilation. Electrical covers service and panel sizing, load calculations, power and lighting layouts, and Title 24 lighting controls. Plumbing covers water, waste, vent, and gas routing plus fixture sizing. You also get the schedules, details, and calculations San Diego plan check asks for.
For most commercial work, yes. San Diego Development Services requires MEP sheets whenever your project adds or relocates HVAC, changes electrical service or panel loads, moves plumbing, or triggers a change of occupancy. Residential projects need them less often, though ADUs, additions, and full remodels usually do once mechanical or electrical loads change.
Yes. Nonresidential and residential Title 24 energy compliance is produced alongside the mechanical and electrical drawings by the same team, so the equipment on your schedules matches the equipment in the energy model. That alignment is one of the most common reasons a San Diego plan check comes back with corrections.
Most MEP packages are delivered in 2 to 4 weeks depending on scope and how quickly we receive the architectural background and existing conditions. We answer DSD plan-check corrections at no extra charge, so a comment on a mechanical sheet does not turn into a month of back and forth.
