Little Rock permit notes
City of Little Rock permits route through Little Rock 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 Arkansas engineer for a restaurant project in Little Rock?
For most restaurants of any meaningful size, yes. Arkansas Occupations Code §1001 requires MEP designs above certain thresholds to be stamped by a licensed Arkansas Professional Engineer. Drawings without a AR seal can stall plan review or trigger code-enforcement action. Pyra Engineering is a Arkansas-licensed firm; the drawings we deliver are stamped and ready for Little Rock permit submittal.
What's typical turnaround on MEP drawings for a restaurant in Little Rock?
Standard restaurant 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/Arkansas MBE-certified certification benefit me on a Little Rock project?
Yes if you're tracking diversity-spend goals on public-sector or large corporate projects. Pyra Engineering's Arkansas MBE-certified and MBE certifications count toward those goals; many City of Little Rock, 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 restaurants 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 code edition will my Little Rock restaurant be reviewed under?
Most AR cities are on 2021 the adopted Arkansas code editions/IPC/IFC for restaurant work, with NEC 2020 or 2023 for electrical. Little Rock-specific amendments apply on top — we draw to the AHJ-adopted edition.
Type I vs Type II hood — how do I tell which I need?
Type I = grease-laden vapors (fryers, griddles, char-broilers, ranges, open-flame ovens). Type II = heat or steam only (dishwashers, dough proofers, non-greasy ovens). When the load mixes, code defaults to Type I for the whole hood.
How is exhaust CFM sized?
Per the adopted Arkansas code editions 507.13.1 prescriptive minimums based on hood type and cooking duty (CFM per linear foot of hood). Wall canopy at medium duty = 300 CFM/ft; wall canopy at extra-heavy = 550. Performance-based design with capture-and-containment testing is the alternate path.
Do you size the make-up air or is the kitchen vendor doing that?
We size make-up air on every restaurant we draw. It's a balance equation with the Type I exhaust, not an afterthought. Vendors often spec MUA units that don't actually balance the hood — we catch that before submittal.
How is gas piping sized for a restaurant cookline?
Per NFPA 54 longest-length method. Most field problems we see come from undersized branches — a 3/4" branch that needs to be 1" because someone summed BTU/h per appliance instead of running the table at the actual length. We size every branch and put the table reference on the iso.
Do I need a grease interceptor and what size?
Most AR cities require one for any restaurant with a 3-compartment sink, mop sink, or pre-rinse station. Sizing per UPC interceptor table or local AHJ amendment — Little Rock and a few others have local amendments. We size to the local AHJ and call out the actual interceptor model so plumbing can quote accurately.
What's the most common second-round permit comment for restaurants?
Across our AR restaurant portfolio, the grease duct enclosure detail per the adopted Arkansas code editions 506.3 — drawings show the duct route but miss the fire-rated enclosure. We draw the enclosure detail explicitly to clear first-round review.
How do you size the electrical service for cooking equipment?
Connected load × demand factor per NEC Article 220. Cooking equipment is treated as continuous load (×1.25). Most AR restaurants land at 200–400A 208V/3-phase service for a 2,000–4,000 sf footprint.
Is fire suppression for the hood your scope?
No. Both the wet-chemical hood suppression system (Ansul, Pyro-Chem, etc.) and the building fire-sprinkler system are out of our scope — separately handled by the fire-protection contractor and fire alarm vendor. We provide the gas shutoff and electrical interlock points they tie into.
Do I need a ADA review for my restaurant?
ADA (Arkansas Department of Licensing and Regulation) Architectural Barriers Program reviews most projects with construction value above the threshold (~$50K). Restaurants almost always trigger it. We identify ADA scope at quote and produce TAS-compliant drawings.
What's the typical permit cycle count for a AR restaurant?
1–2 cycles when first submittal is complete. 3+ when something major is missed (grease duct enclosure, undersized gas piping, missing ADA). We target 1-cycle approval by writing to AHJ amendments up front.
How many restroom fixtures do I need?
Per IPC Table 422.1 — typical restaurant gets 1 WC + 1 lav per 75 occupants per gender, plus 1 service sink and 1 drinking fountain per 500 occupants. Single-occupant unisex restrooms can substitute for the gendered count in many AR jurisdictions.
Do you handle the energy code (the adopted Arkansas code editions + ASHRAE 90.1)?
Yes — every restaurant submittal includes COMcheck (envelope, lighting, mechanical) per the AHJ-adopted the adopted Arkansas code editions edition. Restaurants under 5,000 sf usually clear with prescriptive compliance; larger may need full energy modeling.
What outdoor air rate do you use for the dining room?
ASHRAE 62.1 Table 6.1: 7.5 cfm/person + 0.18 cfm/sf for restaurants. Bar areas are higher. We tag every space against 62.1 and sum to get the OA design rate.
Do I need a separate plumbing permit?
Most AR cities require it. The mechanical permit and electrical permit are usually separate too. We provide a drawing set that satisfies all three permit reviewers.
Can you stamp drawings for both Arkansas and out-of-state locations?
We're licensed in AR and FL. For other states, we partner with locally-licensed engineers when needed for franchise rollouts, but our seal is AR/FL.
What if the cookline equipment changes after permit?
Field-revision is the cheapest path if change is minor (replacing a fryer with another fryer). Major changes (adding a char-broiler to a Type II hood line) require a permit re-submittal. We do field revisions at hourly + a small mobilization fee.
Do you provide construction administration?
Yes — site visits, RFI responses, shop-drawing review for the kitchen exhaust, and final inspection support are standard scope. CA fee is typically 15-20% of the design fee for restaurants.
How do you coordinate with the kitchen consultant / vendor?
Kitchen vendor provides equipment cut sheets and electrical/gas load schedule. We integrate that into the MEP design. We need the vendor schedule before CD set.
Why is your fee lower than a full-service A&E firm?
We're a focused MEP shop with low overhead. We don't carry the architecture studio / interior design / business-development overhead a multi-discipline A&E firm carries. Same stamp, lower fee.
