What building in Lake Mary actually involves
Lake Mary is Seminole's corporate address — Heathrow, top-rated schools, and lots that rarely last on the open market. Every Lake Mary project runs through City of Lake Mary Building Department, and the county-level pieces — impact fees of about $4,000 on our smallest plan, plus Seminole County's review of septic, flood and access where it applies — follow Seminole County rules. Seminole sits inland, so wind design is the Central Florida baseline rather than the coastal upgrade, and the flood exposure that matters here is the St. Johns River basin on the north and east edges.

Do I need a permit to build a detached garage in Lake Mary?+
Yes. A detached garage is a permitted structure in Lake Mary — it goes through City of Lake Mary Building Department, and it has to satisfy setbacks, lot coverage, impervious-area limits and wind-load engineering. We pull it.
Can a detached garage in Lake Mary be converted to an apartment later?+
Yes, if the parcel allows an accessory dwelling. That's why we pre-wire and pre-plumb: roughing in the water, waste and electrical while the slab is open costs a fraction of retrofitting it later. The zoning question still gets answered first.
How long does it take to build a detached garage in Lake Mary?+
Usually 8–14 weeks from issued permit on a standard Lake Mary lot, with permitting ahead of that. Site access and utility runs are the common schedule variables.
What size detached garage can I build in Lake Mary?+
Setbacks, lot coverage and impervious-surface limits decide it, and those are parcel-specific. Send the address and we'll tell you the largest structure your lot actually supports before you fall in love with a size.
Do you build workshops and RV garages in Lake Mary?+
Yes — taller bays, wider doors, thicker slabs and dedicated electrical are all normal requests. The spec follows the use: a woodshop and a boat bay need different things, and both need to be on the permit set from the start.
