Pine Hills began in 1953 with the Robinswood and Pine Ridge Estates subdivisions along Pine Hills Road, grew as a bedroom community for Martin Marietta workers, and spread north toward Silver Star Road through the 1960s and 1970s. That history still shows in the housing. In the ACS 2024 5-year estimates, Pine Hills has about 80,000 residents, a median year built of 1980, 23.5% of homes built between 1950 and 1969 and 60.9% built between 1970 and 1999. Single-family detached houses make up 69.9% of units, and 55.4% of occupied homes are owner-occupied.
The earliest of those houses are now around 70 years old. Age alone does not mean a foundation problem, but it does mean decades of rainy seasons, plumbing changes and additions on the same slab.

What the state's subsidence records show
Pine Hills has more reported subsidence incidents inside its boundary than any other place in our research: about 32 in Florida Geological Survey (FGS) records, from 1961 to May 10, 2026. One, dated July 8, 2019, reads "1 Home threatened, concrete patio sinking into subsidence"; another, from Sept 20, 2023, is on Sunniland Dr.
Read those numbers carefully. FGS records are voluntary, mostly unverified reports, and FGS says "the cause of subsidence is not verified" for most of them. It lists look-alikes such as broken sewer and drain pipes, organic layers that compress, and buried debris. Older records are often located only to a survey section, so per-place counts are approximate.
The 1985 Map Series 110 places Pine Hills' interior point in Area III, described as clayey cover where cover-collapse sinkholes "dominate." It is a regional map, so treat the zone as indicative only, never as a verdict on one street.
Orange County permits apply in Pine Hills
Pine Hills has no city government, so permits go to Orange County. Orange County says structural repairs to foundations need a permit, construction plans are required in most cases, and plans must be signed and sealed by a Florida PE or registered architect when repairs affect structural stability; a Notice of Commencement is required when work exceeds $5,000 (Orange County permit pages). The office is the Division of Building Safety, (407) 836-5550, with online filing through Fast Track. Our Orange County permit guide walks through the steps.
A contractor's visit is not an engineer's report. Diagnosing the cause and writing a structural report is engineering, which only a Florida-licensed professional engineer may do. A contractor's free evaluation is a sales estimate, and Florida has no agency that inspects sinkholes for homeowners (FGS).

Pine Hills foundation questions
Is Pine Hills a city? Who handles permits?
No. Pine Hills is a Census-designated place in unincorporated Orange County, so Orange County's Division of Building Safety handles permits. Orange County says structural foundation repairs need a permit, and plans must be signed and sealed by a Florida engineer or registered architect when repairs affect structural stability. The licensed contractor you choose normally pulls the permit.
Why does Pine Hills have so many reported subsidence incidents?
No source explains it. Pine Hills has about 32 reported subsidence incidents in Florida Geological Survey records, the most of any place in our research, but FGS says most reports are never field-checked and the cause is not verified. Pipe leaks, compressing organic soil and poor fill can look similar. Only a licensed engineer or geologist can say what is happening at one house.
Can a contractor tell me whether my crack is a sinkhole?
A contractor can describe what it sees and quote a repair, but its free evaluation is a sales estimate, not an engineering opinion. Diagnosing the cause is engineering under Florida law, so it takes a Florida-licensed professional engineer. Typical national ranges from This Old House (2026), Bob Vila, HomeGuide (2026) and Angi (2026), estimates not quotes: an inspection runs $400 to $750, an engineer's report about $340 to $1,000.
