Home additions in Altamonte Springs, FL: Right Image Inc (Right Image Builders) is a licensed and insured Florida general contractor (CGC1539321) based in Oviedo, building room additions, second stories, in-law suites, garage conversions and ADUs across Altamonte Springs and Seminole County — structural engineering, permitting and construction under one contract.

Adding on is the most structural work a home can undergo — foundation, framing, roofline, and tie-ins all have to be engineered and permitted correctly. We manage the whole process, from feasibility and design through permits and final finishes.
Additions and accessory dwelling units (ADUs) are handled differently by each jurisdiction — the rules change between each city and the unincorporated parts of Seminole, Orange and Osceola counties. We build to what actually applies to your Altamonte Springs lot.
Add a bedroom, primary suite, or great-room bump-out with a foundation and roofline that match the existing home.

We work throughout Altamonte Springs — from Sanlando Springs and Spring Oaks to Spring Valley, Lake Brantley, Lake Orienta. Altamonte Springs is a dense, amenity-rich Seminole County hub near I-4 and Cranes Roost, and it sits in Seminole County, part of the Greater Orlando area we cover from our base in Oviedo.
Permitting for an Altamonte Springs home addition goes through City of Altamonte Springs Building Division. Altamonte Springs runs its own building department, so plan review and inspections stay local. We deal with that office directly on your behalf.
Alongside Altamonte Springs, we regularly take on work in nearby communities including Maitland, Casselberry, Longwood and Winter Park.
Every Altamonte Springs home addition we take on is run by the same licensed general contractor (CGC1539321) that pulls the permit — so there is one point of accountability from the first walkthrough in Sanlando Springs or Spring Oaks through final inspection with City of Altamonte Springs Building Division.
Altamonte Springs is dense and largely 1970s–80s — single-family streets in Spring Oaks, Sanlando Springs and Spring Valley, plus many condominium and townhome associations around Cranes Roost and SR 436. Condo and HOA rules often decide what a remodel can change on the outside. For additions and ADUs, it means confirming the zoning, setbacks and any HOA or architectural review for your specific lot before design starts.
Altamonte Springs does not permit ADUs, granny flats or garage apartments by right anywhere in the city. A guest house without kitchen facilities is permitted in the R-1AAA, R-1AA and R-1A districts, one per home; a guest house with cooking facilities needs a conditional use approved by the Planning Board after a public hearing. The R-1 districts don't allow guest houses.
Source: Altamonte Springs LDC §3.6.2(k) and §3.6.3(c), per the city's guest-house FAQ, City of Altamonte Springs (checked October 2026). Rules change, and HOA covenants can be stricter than the code; we confirm both for your parcel before design.
Typical time: about 3–5 months from permit to finish for a room addition; second stories and ADUs take longer. The stages are the same for every addition we build across Greater Orlando; what changes is the size of the job and the review time at your building department.
