Retail permit timelines are the single most underestimated input in US store-opening schedules. International brands routinely walk in with European or APAC mental models — file it, get it in two weeks, build — and then watch the LADBS plan check eat four months of their opening calendar.
The table below is a market-by-market range for typical specialty retail TI work. The numbers cover plan check from submission to permit issuance — they do not include the time spent assembling the filing package, which usually adds 2–4 weeks on its own.
Typical retail TI permit timelines, by market
| Market | Filing type | Typical timeline | Source |
|---|---|---|---|
| New York City | Alt-2 (TI without structural) | 4–8 weeks | DOB Guard |
| New York City | Alt-1 (TI with structural/use change) | 8–16 weeks | DOB Guard |
| Los Angeles | Standard TI | 4–6 months (16–24 weeks) | Razi Architects, LADBS |
| Miami (City + Miami-Dade) | Commercial TI | 8–14 weeks | Field benchmarks |
| Chicago | Standard Plan Review | 6–12 weeks | Field benchmarks |
| Dallas | Commercial Build-Out | 6–10 weeks | Field benchmarks |
| Houston | OAE / Houston Permitting Center | 6–10 weeks | Field benchmarks |
| Atlanta | Commercial TI | 6–12 weeks | Field benchmarks |
| San Francisco | DBI commercial | 12–24 weeks | Field benchmarks |
| Boston | ISD commercial | 8–16 weeks | Field benchmarks |
| Seattle | SDCI commercial TI | 10–18 weeks | Field benchmarks |
What drives the range within a market
Inside any given market, the actual timeline depends on three things: the filing type you choose, the AHJ's current workload, and how many rounds of plan-check corrections your package runs through.
Filing type
NYC is the clearest example. A typical specialty retail TI on an existing certificate of occupancy can usually file as an Alt-2, which is the faster 4–8 week path. The moment the scope touches structural elements, occupancy classification or use, it becomes an Alt-1 — 8–16 weeks. The difference is the difference between opening for the holiday season and missing it.
LA is the opposite shape. There is no equivalent fast track for retail TI inside LADBS. Per Razi Architects: “Permitting (Standard TI): 4–6 months. Yes, really. LADBS is thorough. Plan checks often go through 2–3 rounds of corrections… Total Timeline: Expect 9–12 months from hiring an architect to opening your doors. If you are told it can be done in 3 months, be very skeptical.”
AHJ workload
Per DOB Guard, NYC's Department of Buildings processes more than 175,000 permit applications a year. The published timelines compress in slower quarters and stretch in busier ones. Q1 is typically faster than Q4. Your filing date matters more than your package quality at the margin.
Plan-check corrections
Every market runs plan-check rounds. A clean first submittal, prepared by a US-licensed architect who knows the AHJ's house style, will typically clear in 1–2 rounds. A submittal prepared offshore, or by an architect new to the jurisdiction, routinely runs to 3–4 rounds. Each round adds 2–4 weeks.
The failure modes that blow the schedule
- Filing too late. You cannot file until you have executed the lease and your design package is at CD 90%. If either is late, the whole opening calendar moves.
- Wrong filing type. Choosing Alt-1 when Alt-2 would have worked, or filing for a use change when you could have inherited the existing C of O.
- No pre-application meeting in jurisdictions that reward them. LA, San Francisco, Boston and Seattle all benefit from a pre-application conversation with the plan checker. Skipping it is the single most preventable cause of extra correction rounds.
- Landmarks or special-district review missed. NYC LPC, SF Planning, Miami HEPB and similar bodies add 4–12 weeks when triggered. The trigger is usually exterior signage, storefront modification or facade work. Discover this early.
How to use these numbers
Work backward from your published opening date. Add construction duration (8–16 weeks for typical specialty retail TI). Add the permit window above for your market. Add 2–4 weeks for filing assembly. The result is your earliest lease commencement date for an on-time opening.
If the math says your lease commencement has to be 9 months before opening day, that is what it is. Trying to compress it almost always shows up as cost — accelerated construction premiums, weekend AHJ filings, expediter fees — without buying the time back.
