ADU Builder & Contractor in Los Gatos

Los Gatos Lots Are Rarely Simple

Los Gatos has two kinds of ADU projects and they barely resemble each other. Down on the flats near downtown and around Blossom Hill, you are working with older homes on established lots where the constraint is space and mature trees. Up in the hills, the constraint is the ground itself: slope, access, drainage, and getting materials to a site that a concrete truck cannot easily reach.

As an ADU builder and contractor in Los Gatos, the first thing we do is establish which project you actually have. That determines the budget more than square footage does.

The ADU Types We Build

Each property leans toward a different answer, and part of our job is telling you which one fits before you pay for drawings.

  • Detached ADUs, a standalone unit in the yard, the strongest option when there is usable flat area and you want real separation for a tenant or family member.
  • Attached ADUs, a new unit built off the existing house, which is often the practical answer on a hillside parcel where a second foundation on slope is expensive.
  • Garage conversion ADUs, using a footprint that already exists, usually the fastest and cheapest route where the structure is sound.
  • JADUs, a junior unit carved out of the existing home, capped at 500 square feet, with its own entrance and an efficiency kitchen.

More on how we approach each of these is on our ADU construction page.

State Law and the Town of Los Gatos

State ADU law has removed most local discretion. It restricts how far a jurisdiction can limit unit size, parking, and owner occupancy, and it mandates ministerial review, meaning a compliant application is approved without a discretionary hearing.

Los Gatos is a town rather than a city, and it runs its own Community Development Department for planning and building permits. The submittal requirements, plan check comments, and inspection scheduling are the town's, not the county's and not the neighboring city's. Los Gatos also applies hillside development standards to properties above the flats, and those affect grading, height, and how visible a structure is from off site. We handle that process directly, so you are not the one chasing corrections between plan check rounds.

Building on Hillside Parcels

If your property is in the hills, the honest conversation happens early. Slope drives foundation design, and a stepped or pier foundation on a steep lot costs considerably more than a slab on flat ground. Access matters just as much: narrow, winding roads limit what size truck can deliver, and material staging on a site with no flat area adds labor to every phase.

Drainage is the third piece. Water moving downhill across your parcel has to be managed around a new structure, and getting that wrong shows up years later as a foundation problem. None of this makes a hillside ADU a bad idea. It makes an accurate assessment before design essential, which is exactly what we do at the site visit.

Design-Build Under One Contractor

We run ADU projects as design build, so the same team handles design, permitting, and construction. The alternative, where a designer produces a set and hands it off at bid time, is where budgets tend to break, and it breaks worst on complicated sites. When the people drawing the unit are the people building it, the plan reflects real costs and real site conditions from the start.

It also means one point of contact. Homeowners searching for ADU contractors near me are usually trying to avoid coordinating four separate parties, and a single general contractor removes exactly that. Our ADU contractor services page covers what each phase includes.

Quality of Build Over Volume

We are a licensed general contracting company based in San Jose, owner operated by Becir Molabecirovic, serving Los Gatos and the surrounding Santa Clara County cities. We keep the number of concurrent projects low deliberately, because that is what the work requires on sites like these.

Our portfolio includes whole house remodels in San Jose, Los Altos, and Portola Valley alongside kitchen and bath work and home additions. Portola Valley in particular is hillside work, and an accessory dwelling unit contractor who has built on slope brings judgment a volume ADU shop does not have. There is more about how we work on our about us page.

Frequently Asked Questions

Do I permit through the Town of Los Gatos or through the county?

Through the town. Los Gatos issues its own planning and building permits through its Community Development Department, and we manage the submittal and plan check for you.

Can I build an ADU on a hillside lot?

In most cases yes, but the design has to respond to slope, access, and drainage, and hillside development standards apply. The cost difference against a flat lot is real, which is why we assess it before you commit to a design.

Can the town deny my ADU?

If the design meets state and local standards, review is ministerial and it is approved without a discretionary hearing. Denials generally come from plans that miss a size, setback, or code requirement, which the design phase exists to prevent.

What if my home is in a historic district?

Older neighborhoods near downtown can carry additional design expectations. That does not prevent an ADU, but it shapes materials, roofline, and placement, and it is worth confirming early rather than at plan check.

How big can my ADU be?

State law protects a minimum allowable size regardless of local rules, with larger units possible depending on lot coverage, setbacks, and whether the unit is attached or detached. We size it against your specific parcel rather than a general number.

Create Your Dream ADU Designed Just for You

Every ADU project starts with a site evaluation. We'll visit your property, take measurements, review setback requirements, and discuss your goals. From there, we'll recommend floor plans that make sense or start designing something custom if that's the better route.
