How Long Does a Building Permit Take?

Local Tips

• LADBS requires a separate Certificate of Occupancy inspection for any change of use, even when the scope of work is already covered under an active building permit — meaning a single project can involve parallel inspection tracks that both need to clear before the space can be legally occupied.
• Los Angeles has a dedicated mandatory soft-story retrofit program with its own fast-track queue, but applications require an engineer-stamped retrofit letter submitted upfront — starting the process without that letter in hand is one of the most common causes of rejection.

Local Tips

• EPIC-LA serves both unincorporated Los Angeles County and a large number of contract cities — meaning a 'county' permit may actually cover work inside a specific incorporated city that contracts its building department to LA County DPW, so the same permit portal handles multiple jurisdictions under one roof.
• LA County permit numbers span 47 distinct prefix formats across the EPIC-LA system — including compound prefixes like UNC-*, WLV-*, LKW-* for community areas, standalone BLD/ELEC/MECH/PLMB prefixes, and hyphenated formats like FEPC2024-0885 for environmental work — which can make it confusing to tell at a glance which track a permit is on.

Local Tips

• Pomona operates on a four-day work week for its Building and Safety counter (Mon-Thu), so applications submitted late Thursday typically don't get a response until the following Monday — planning submittal timing around the Friday closure is standard practice for Pomona contractors.
• Pomona runs its own EnerGov permit portal separate from the surrounding Accela cities (Ontario, Pasadena, San Bernardino County), so contractors working across Inland Empire cities have to juggle a different login and a different permit number format for Pomona jobs.

Local Tips

• Ontario is one of the largest logistics, warehouse, and industrial markets in Southern California, so industrial building permits tied to warehouse construction and tenant improvements are a disproportionately large share of the city's permit volume compared to neighboring residential-dominant cities.
• Ontario International Airport drives additional review for projects inside the airport influence area — proximity to the runway affects height limits, noise overlays, and in some cases requires FAA airspace review on top of the standard building permit process.

Local Tips

• Pasadena has extensive landmark districts and individually designated historic structures — any exterior alteration or addition inside a landmark district typically requires design review approval before a building permit can be issued, which can add weeks or months to a project's timeline.
• The Arroyo Seco and surrounding scenic areas are subject to additional design review and hillside considerations, so projects adjacent to the Arroyo face review layers that projects elsewhere in Pasadena don't encounter.

Local Tips

• San Bernardino County covers the largest land area of any county in the contiguous United States, including desert, mountain, and high-fire-hazard areas — projects outside the built-up Inland Empire often require additional fire clearance, defensible space verification, and access road review on top of standard building permit review.
• Title 24 solar and energy-efficiency requirements drive unusually high solar permit volume across unincorporated SBC, and the county handles this volume through the Accela Citizen Access portal alongside traditional building, grading, and trade permits.

Local Tips

• San Diego runs a one-stop-shop model: building, mechanical, electrical, plumbing, grading, solar, and ADU permits are all issued by a single department (DSD), so one Accela account covers everything instead of juggling multiple agencies.
• Permits submitted after January 16, 2018 live in the current Accela Citizen Access portal, while older permits remain in the legacy OpenDSD system — meaning some jobs require checking both when researching project history.

Local Tips

• Sacramento reports that roughly 38% of ADU plan check submittals are returned for corrections on the first review, which is a major driver of the 4-6 month average timeline contractors see on custom ADU projects.
• The city offers SolarAPP+ for instant automated residential solar permits on eligible systems — one of a small number of California cities to deploy the SolarAPP+ toolkit, which bypasses traditional plan check entirely.

Local Tips

• Charlotte is actively migrating every contractor and homeowner account from its legacy WebPermit portal to Accela Citizen Access — the county has stated the old portal 'will not remain open indefinitely,' so every user is being forced to set up a fresh Accela account with a new workflow even though surety bonds and license numbers carry over.
• Charlotte's permit numbers use a distinctive TYPE-YEAR-SEQUENCE format such as LDC-2024-001234, ZUP-2024-000567, or GRS-2024-000123 — different from most other Accela cities' numbering conventions and recognizable at a glance.

Local Tips

• Mecklenburg County uses a shared 'X-number' account system with Charlotte Land Development: contractors need a verified professional license before they can attach a bond or trust account to their X-number for permit payments, which is a common stumbling block for new accounts.
• Mecklenburg County Code Enforcement serves both unincorporated areas and several partner towns for building inspections, so a 'county' permit may actually cover a project inside a specific town depending on the inter-local agreement — always check which jurisdiction the permit was pulled under.

Local Tips

• Fort Lauderdale's LauderBuild portal has a unique 'Walk-Thru' permit system: applications can be submitted at any time but are only processed during a narrow next-business-day intake window (typically 8:00-9:30am), so missing the slot means waiting an extra day regardless of how simple the permit is.
• Hurricane recovery cycles create massive permit surges in Fort Lauderdale — storm season typically drives large spikes in roofing, electrical, and structural permits, and wait times on inspection scheduling tend to grow accordingly during recovery.

Local Tips

• Denver is a consolidated city and county, so a single permit covers what would otherwise be two separate filings in most other markets — one Accela account at CPD handles building, zoning, and most trade permits across the entire Denver jurisdiction.
• Effective December 2025, Denver added a 2.5% credit card surcharge on permit payments through the CPD portal, which changed how many contractors and homeowners decide to pay for fees on larger permits.
