Westchester Single-Family Renovation and Addition Permits

Westchester is densely developed single-family residential in the 1950s and 1960s building stock with concrete masonry unit walls, original aluminum jalousie windows, and tar-and-gravel built-up roofs nearing or past their service life. Common Westchester permits include impact window and door replacement, HVHZ roof tear-off and replacement, foundation underpinning for soft-soil settlement, kitchen and bathroom remodels, and rear-yard additions. The Miami-Dade unincorporated minimum permit fee is $165 USD with percentage rates at 1.5% to 2.2% residential and 2.0% to 2.8% commercial. Hire Endless Life Design to consolidate the impact window, roof, and addition permits on one application to compress the timeline.

Tamiami Commercial and Tenant Improvement Permits

The Tamiami area along the Tamiami Trail and Bird Road contains concentrated neighborhood commercial, professional offices, medical and dental offices, and small-format retail. Commercial plan review at Miami-Dade unincorporated runs 30 to 60 business days, with reinspection fees at $185 USD each. The Florida Building Code commercial requirements apply, with the Florida Mechanical Code, Florida Plumbing Code, Florida Fuel Gas Code, and Florida Fire Prevention Code each requiring sub-permit submissions. Order the tenant improvement permit through Endless Life Design to coordinate the full code package.

Olympia Heights ADU and Garage Conversion Compliance

Olympia Heights residents have aggressively pursued ADU and garage conversion permits since the post-HB 4441 framework expanded accessory dwelling options in Miami-Dade RU-1. Garage conversions to habitable space require replacement parking on the lot per the zoning code, full ventilation and natural light compliance, and electrical service upgrades from the typical pre-1990 garage 100A panel to a 200A residential service. Septic-to-sewer conversions are commonly required because the existing drainfield was sized for the original bedroom count. Buy the ADU and conversion package through Endless Life Design to include the WASD sewer connection, FPL service upgrade, and zoning compliance on one scope.

Fountainebleau Multifamily and Mixed-Use Construction

Fountainebleau contains a high concentration of 1970s and 1980s garden-style apartments and two-story walk-up condominiums between West Flagler Street and Eighth Street, with active SB 4D milestone enforcement on any building three stories or taller. The 30-year and 25-year coastal milestone framework drives a continuous pipeline of facade rehabilitation, balcony reconstruction, and SIRS reserve-funded capital projects. Plan review for SB 4D milestone work runs 30 to 90 business days. Schedule the milestone-coordinated rehabilitation through Endless Life Design to consolidate the engineering report, the SIRS update, and the building permits.

Miami-Dade Unincorporated Permit Workflow and ePlan Submittal

Miami-Dade unincorporated uses the iBuildMiami online portal for permit submission with PDF flattening to 100 MB per file, signed and sealed by Florida-licensed design professionals, on the county cover sheet listing contractor, design professional, and owner. Plan review begins after the intake review confirms the submittal is complete, and incomplete submittals are rejected at intake without entering the queue. Plan review averages 14 to 28 business days residential and 30 to 60 business days commercial, with longer cycles on SB 4D milestone and CCCL projects.

Public Works Right-of-Way and Driveway Apron Permits

Miami-Dade Public Works issues right-of-way permits for any work crossing the county roadway, sidewalk, or swale at $185 USD per closure day plus engineering review. Driveway apron replacement and modification requires a separate ROW permit at $345 USD with a Florida Department of Transportation review when the work crosses a state road frontage. Sidewalk repair adjacent to construction is mandatory under the county code, and any sidewalk panel cracked more than 1/2 inch must be replaced before final inspection. Call 811 Sunshine two business days before any underground work — striking the FPL primary or the WASD water main is a $20,000 USD utility-restoration fine.

School Concurrency, Impact Fees, and Mobility Fee Assessment

New residential units in unincorporated Miami-Dade trigger school concurrency review by Miami-Dade County Public Schools at 60 business days with a $135 USD application fee. Impact fees include road at $4,213 USD per single-family unit, park at $1,116 USD, school at $3,247 USD, fire-rescue at $415 USD, and police at $339 USD. Mobility fees in transit-oriented districts replace road impact fees at $5,800 USD to $9,200 USD per unit. ADUs under 750 square feet on owner-occupied lots qualify for 50% impact-fee reductions under HB 4441. Order the impact-fee credit package through Endless Life Design.

Government Accountability and Corrected Facts

The Miami-Dade unincorporated permit page still references the 2018 Florida Building Code in several legacy navigation breadcrumbs even though the 8th Edition 2023 FBC is operative — Endless Life Design submits to the current code. The iBuildMiami portal occasionally displays the pre-2024 fee schedule on certain permit types when the fees were updated October 1 2024; Endless Life Design verifies the current fee at the cashier counter before submission. The Public Works ROW permit page does not currently list the 2024 $185 USD per day base rate on the residential section, and contractors who file at the obsolete rate are billed the difference at counter.

The SB 4D milestone framework applies to buildings three stories or taller — including the many 1970s and 1980s walk-ups in Fountainebleau — and condominium boards continue to be misinformed by older engineering firms that "the 40-year rec is still the standard." It is not. The 30-year inland and 25-year coastal accelerated timeline is the operative law since July 1 2022.

Early-start passes do not exist in unincorporated Miami-Dade, and code enforcement will not back you up when you mobilize before permit issuance. File the Notice of Commencement before the contractor mobilizes and record the Notice of Termination within 30 days of final inspection. Watch the 90-day lien window — Westchester and Olympia Heights have a high concentration of cash-strapped homeowners who default on contractor payments, and the lien deadline is unforgiving.

Refresh the survey if older than 90 days at $800 USD to $8,500 USD. Never break through the septic tank during foundation excavation — many older lots are still on septic and a $20,000 USD DEP environmental fine plus pumping and replacement at $4,000 USD to $9,000 USD applies. Reinspection fees are $185 USD each. Permit expiration is 180 days with one 90-day extension at $115 USD. Retain three independent engineers because losing one mid-project strands the closeout. Confirm the contractor's Florida Certified License is active, workers compensation insurance is in force, and general liability is at least $300,000 USD residential and $1,000,000 USD commercial.
