Detached ADUs in San Jose

All three are accessory dwelling units, but they are not the same project. A detached accessory dwelling unit is new construction from the ground up, so nothing about it is inherited from the existing house.

• Full privacy, with a separate entrance and no shared interior walls
• Independent utility runs, usually trenched from the main house or the street
• Its own foundation, framing, roof structure, and insulation envelope
• Layout freedom, since you are not working around an existing garage footprint or bearing wall
• Stronger rental appeal, because tenants treat it as a real house rather than a converted room

A garage conversion is faster and usually cheaper. A backyard ADU costs more and takes longer, and it is the option most of our clients pick anyway once they compare what each one is worth in five years. Our ADU construction services cover all four types, so we walk through the tradeoffs before anything gets drawn.

The part of a detached build that homeowners underestimate is everything below grade. Water, sewer, gas, and electrical have to reach the back of the lot, which means trenching across the yard and, in some cases, upgrading the main panel to carry the added load.

Santa Clara County soils vary quite a bit, and expansive clay shows up often enough that a soils report changes the foundation approach on a real share of the projects we take. We plan the trench routes around mature trees and hardscape early, so the landscaping you keep is a decision rather than an accident.

We are a licensed general contracting company based on Fruitdale Avenue in San Jose, owner operated by Becir Molabecirovic. We take fewer projects than a volume builder does, because the difference between an ADU that holds up and one that does not is in framing, flashing, and moisture detailing that nobody photographs.

Our work covers whole home remodels and additions in San Jose, Los Altos, and Portola Valley alongside our ADU builds, which is why we are comfortable when a backyard unit turns into a wider conversation about the main house. You can see finished work in our project portfolio.
