ADU Construction and Garage Conversions

The difference between an ADU that pencils and one that stalls is the paperwork. We verify zoning, setbacks, and utilities on your parcel before you spend on plans, then run the ministerial submittal ourselves.

What's included

• ADU design and construction — detached and attached
• Garage conversions to livable, permitted space
• Junior ADUs and garage additions above existing structures
• Kitchenettes, bathrooms, and separate utility connections
• State and local ADU permit compliance (ministerial review)
• Fire separation and access requirements
• Utility tie-ins, HVAC, and insulation to code
• Final inspection and certificate of occupancy support

Why homeowners pick Ofir

• Permitted, rentable units with design and inspections handled in-house.
• Licensed and accountable — CSLB #1036242, verify us at cslb.ca.gov.
• One contract for design, permits, every trade, and the final walkthrough.
• Permits and inspections handled in-house by our own office.
• A polite, thorough crew — the words our Google reviewers use most.

Signs it's time to call

• The garage hasn't parked a car in years
• You want rental income but don't know if your lot qualifies
• Family needs a nearby place that isn't your guest room
• You've heard ADU rules got easier but not what they mean for your parcel

Timeline: Plan and permit stages commonly run two to three months on the ministerial ADU path; construction eight to sixteen weeks depending on size and whether it's a conversion or a detached build.

Getting ready: Garage-conversion prep is simple — empty the garage. Detached ADUs need a clear path for equipment and materials. Either way we confirm utility routes and staging during the site visit, so surprise is not part of the estimate.

How we price ADU and Garage Conversions — and stand behind it

Every ADU and Garage Conversions project starts with a free site visit and a written estimate: scope, line items, material allowances, and a calendar built from what we actually saw on your property — not a number guessed over the phone. The document says plainly what is included and what is not, so the only surprises are the pleasant kind. Change orders show up when you change the scope; if we overlooked something during our own walkthrough, correcting it is on us. Payment follows completed milestones rather than large up-front sums — California caps residential deposits at 10% or $1,000, and our contracts hold to that to the dollar. When the work is finished we walk it with you room by room against the written scope, close out the permit record, and leave the site clean. After move-in, one phone call reaches the same office that ran your project — the people who wrote the estimate answer the phone, not a new estimator starting from zero.
