Permits in Miami: what investors always missPermits, May 2026, 4 MIN.Permitting is where good deals slow down and where out-of-town investors lose the most time. It's rarely one big mistake. It's a handful of small, avoidable ones that push a two-month approval into a six-month one. Here's what actually trips people up in Miami-Dade and its municipalities.The Notice of Commencement is not optional paperworkBefore work starts on most projects above a minimal cost threshold, Florida law requires recording a Notice of Commencement (NOC) with the county: it identifies the property, the owner, and the contractor, and it protects everyone's lien rights. Investors coming from states without an equivalent requirement sometimes skip it or file it late, which can create real problems if a payment dispute comes up later and can also hold up final inspection if the inspector checks for it and it isn't on file.Owner-builder permits look cheaper and almost always cost moreFlorida allows property owners to pull permits themselves as an "owner-builder" without a licensed contractor of record, and it's tempting for investors trying to save on general contractor markup. In practice, owner-builder permits come with restrictions: the owner has to occupy the property or intend to, in most cases, and can't simply flip a property built under an owner-builder permit without running into resale disclosure issues and, sometimes, direct questions from the buyer's lender or insurer about who actually supervised the work.For investment properties specifically, pulling permits under a licensed contractor of record from the start avoids this entirely and, in our experience, moves through plan review faster because reviewers are used to seeing a contractor's information formatted correctly.Expired permits on the record follow the property, not the personThis is the single most common surprise we see. An expired, unfinaled permit from a previous owner doesn't disappear when the property sells. It sits on record and a new owner has to resolve it, sometimes by re-exposing the original work for inspection. Before submitting anything new, we check for open permits on file and get them closed or addressed as part of the same submission, rather than letting the county flag it mid-review and stall the new permit too.A clean, coordinated drawing set is the fastest thing you can controlPlan reviewers move fastest through submissions where architecture, structural, and MEP drawings actually agree with each other: same dimensions, same equipment locations, no contradictions between sheets. Most of the delay we see in first-round reviews isn't about the design being wrong; it's about drawings from different disciplines that were never fully coordinated before submission, which generates a round of comments, a resubmission, and another review cycle.Submitting one coordinated set the first time, architecture, structure, and MEP resolved together rather than stapled together, is the single highest-leverage thing an investor can control in the whole permitting timeline.Service: Permit expediting
