The approval layer over Hollywood premises
Mold assessment is licensed by the state rather than permitted by the town, which is the opposite of how plumbing or electrical work is handled here. No Broward municipality issues a mold permit or keeps a mold register: the assessor licence comes from the Florida Department of Business and Professional Regulation under Chapter 468 Part XVI, it is searchable on the state register, and section 468.8419 bars the holder from remediating a structure they assessed within twelve months. That is identical at every address in the county and we will say so rather than inventing a local office. What Hollywood adds is a documented flood history and a large stock of 1960s buildings that have been altered repeatedly, so the question of when a water event happened comes up here more often than anywhere else in the county.
On a commercial building that licensing position sits underneath a more immediate practical problem, which is that the premises cannot close. Three things make this work different from a house, and none of them is the science.
Occupancy changes the readings. People, a door cycling constantly and a kitchen running will move humidity, particle counts and pressure relationships in ways an empty building does not. Where the question is what occupants are exposed to, sampling has to happen during trading. Where it is whether a particular void holds a source, it has to happen when the building is quiet. Most jobs in Hollywood need both, and deciding which is which beforehand is most of the planning.
Zones rather than rooms. A commercial building is a set of air handling systems and each is effectively a separate building. Sampling by room in premises with four rooftop units produces a great many readings of four air masses; sampling by zone, with a control per zone where the intakes differ, produces an answer. It is also what keeps the cost sane, because zone count rather than floor area drives the work.
People are going to ask what it means. Staff, tenants and sometimes a regulator, so the report is written to be circulated, and it states plainly that a building assessment makes no findings about anybody's health.
The commercial position in Hollywood is the one published on every page of this site, because the rate card is not a Fort Lauderdale rate card. A flat price by property size, agreed before anyone drives out, with the accredited laboratory fee already inside it. It does not rise if the samples come back positive, nothing is added for the drive, and we take no payment of any kind from anyone who removes mold.

What Hollywood itself changes
The buildings in Hollywood
Hollywood has a median build year of 1969 across 72,843 housing units, which places most of the city in the first generation of Florida housing designed around central air conditioning from the outset rather than having it retrofitted later. That sounds like an advantage and it cuts both ways. These houses were designed to be cooled, so the envelope is tighter than the pre-war stock further south, but they were designed to a 1960s understanding of it: ducts sized generously, equipment specified by rule of thumb, and very little attention paid to what happens to humidity when the machine is satisfied early. Forty-three per cent of the stock is single-family detached and another 19% sits in buildings of fifty units or more, so the city carries both the single-storey slab house and the mid-century beachside block, and those two fail in completely different ways.
Where it hides in these buildings
The 1960s single-storey stock here puts almost everything that matters out of sight in two places. The first is the attic, where the air handler frequently sits along with duct runs that were insulated to the standard of the day and have had sixty years to compress, slip or split. The second is the slab edge, where a terrazzo or tiled floor meets an exterior block wall, which on a house of this era has no capillary break worth the name. Growth at a wall base behind furniture is the commonest Hollywood finding and it is invisible until something is moved.
The cooling systems here
Original ductwork is the defining piece of equipment in Hollywood, because the cooling has been replaced two or three times since 1969 and the duct almost never has. What that produces is a modern, efficient condenser and air handler blowing into a distribution system designed for a different machine, with insulation that has aged out and joints that have opened. In the beachside blocks the picture is different again: through-wall and packaged terminal units serving one room each, with no whole-house dehumidification anywhere in the building and a wall sleeve detailed half a century ago.
