I had a developer client last March who wanted to open a dental office in a Las Vegas valley strip mall. The lease was signed. The build-out budget was tight. The doctor wanted to see patients within 60 days.
We submitted in Henderson, Nevada — not Las Vegas city, not unincorporated Clark County. The permit issued in 24 hours. One business day. Twenty-four hours.
I wish that were a typo. It's not. We picked up the stamped set the next morning at the Henderson Building Department on Water Street.
What Henderson does that other cities don't
Henderson runs an over-the-counter (OTC) commercial TI program that lets a designer of record submit, sit for review, answer questions, and walk out with a permit — in a single day. The program isn't unique conceptually (Phoenix has something similar, San Diego has a DSD lite track, Long Beach has Express Plan Check). But Henderson's actually delivers what the brochure promises.
The qualification thresholds are tight, on purpose. To be OTC-eligible, the project has to be:
- A tenant improvement, not ground-up.
- Under 5,000 square feet of floor area being modified.
- No change of occupancy classification (an M to A-2 conversion disqualifies you).
- No structural modifications beyond non-load-bearing partition walls.
- No exterior changes to the building shell.
- MEP scope limited to within the tenant footprint (no new gas service, no new water service, no service upgrades).
About 60% of dental, retail, and office TIs in the Las Vegas valley qualify on those criteria. Restaurants typically don't (the change of occupancy alone usually disqualifies). Medical offices often qualify if there's no specialty exhaust system being added.
How the Henderson OTC day actually goes
I'll walk you through the dental office. We arrived at 8:15 AM with the printed set, the application forms, and the OTC-eligibility checklist filled out. The desk attendant — Marcus, who''s been there for years — checked the eligibility list, took our application, and gave us a number. Number 7. They take a max of 12 OTC walk-ins per day.
We sat in the waiting area for 90 minutes. At 9:50, the building reviewer called us back to a conference room. He spent 25 minutes reading the set with us across the table. Two questions came up — one about an accessible-route detail at the reception desk, one about a fire-rating callout on the corridor wall. We had answers ready (the route detail was on sheet A2.2; the fire rating was 1-hour per UL U419). He marked his approval on the set.
He routed us to mechanical/electrical/plumbing review next. Three more reviewers, three more 15-minute conversations. The plumbing reviewer wanted us to clarify the dental-suction line venting. We sketched the modification on his marked-up sheet, signed it, and he approved. By 12:40 PM we had four sign-offs and a pass-through to the cashier.
Permit fees were $1,840 — Clark County valley average. We paid by card. The permit document printed at 1:05 PM. We were in the parking lot by 1:15. Total elapsed time from doors-opening to permit-in-hand: just under five hours.
Why Vegas city and unincorporated Clark County don't have this
I''ve asked. The Henderson process works because Henderson Building Department made a deliberate decision in 2019 to staff for daily walk-in volume. They added two MEP reviewers and a senior building reviewer specifically for the OTC counter. That choice has political consequences — it requires committed staffing budget that other Las Vegas valley AHJs haven't matched.
Las Vegas city building has a similar program on paper. In practice, OTC review at City of Las Vegas runs 5-10 business days because the reviewers are also handling regular plan-check queue, and walk-ins go to the back of that queue. Clark County unincorporated doesn't run an OTC program at all.
What this means if you have a Vegas-area project
Three things:
- If the parcel is in the City of Henderson AND your project meets the OTC eligibility criteria, file in Henderson. Even if your other location options are technically faster on paper, Henderson is faster in reality.
- If your parcel is just outside Henderson city limits but you have flexibility on which storefront to lease, factor Henderson's permit speed into the leasing decision. We've seen tenants pay $200-$400/month more in lease just to be in a Henderson address — and recover it inside six months from faster build-out.
- If your scope disqualifies you from OTC (most restaurants, most ground-up, most service upgrades), Henderson's standard plan-check track is still faster than Las Vegas city. Average we've seen: 14 days at Henderson standard versus 22-28 at Vegas. The advantage is smaller but still meaningful.
Henderson Building Department is the unsung permit speedrun of the Southwest. Most West Coast developers have never heard of it. The ones who have, plan their lease decisions around it.
We've now filed nine OTC permits at Henderson in the last 14 months. Average elapsed time: 6.5 hours. The 24-hour benchmark for the dental office included an overnight wait for the cashier counter to reopen. If we'd arrived 90 minutes earlier, the permit would've issued same-day. Same as the other eight.
