Accessory Dwelling Units

A Second Home On Land You Already Own

California has spent the last several years making ADUs dramatically easier to build. Most homeowners still assume their lot does not qualify. Usually it does.

We build detached ADUs, attached additions, garage conversions and junior ADUs — from the zoning check and site plan all the way through final inspection and utility hookups.

The first thing we do is confirm what your specific parcel allows before you spend a dollar on design: setbacks, lot coverage, height limits, utility capacity and whether a separate meter makes sense. Then we design to what actually gets approved instead of what has to be redrawn twice.

What Drives Your Price

We price every project individually after walking the space — so rather than publish numbers that would not apply to your home, here is what actually moves the total, and how to compare bids fairly.

Your estimate is free, written and line-item. We walk the space, measure, and put every line in writing with allowances stated in dollars so you can raise or lower them yourself. No obligation, and no number scribbled on the back of a business card.

What Moves the Number

  • Detached new construction vs converting an existing structure
  • How far utilities have to be trenched from the main house
  • Whether a separate electrical meter and service upgrade are required
  • Soil and foundation requirements on your specific lot
  • Site access — a backyard with no equipment access costs more to build in
  • Finish level, which on a rental you may deliberately keep modest

How to Compare Bids Fairly

A low bid is often just a smaller scope. When you compare estimates, check that each one includes permits, the same allowances, debris removal, and the same level of demolition. Ask every contractor what happens when they find something unexpected — the answer tells you more than the number does.

Verify any license at cslb.ca.gov before you sign anything. Ours is #1125128.

How Long It Takes

Real durations from our own jobs. Permitting is the phase most homeowners underestimate — it is controlled by the building department, not by us.

Where We Work

ADUs on the Central Coast

ADU rules differ between the City of Santa Maria, unincorporated Santa Barbara County, Lompoc and the smaller jurisdictions around us. We check your parcel against the ordinance that actually applies to it, not the general state rule, before anyone starts drawing.

FAQ

ADUs — Questions

Can I build an ADU on my lot?

Most likely. State law now requires cities to permit ADUs on nearly all single-family lots, subject to size and setback rules. We check your specific parcel first, free, before any design work starts.

How long does an ADU take?

Plan on roughly 2 to 5 months for design and permitting, then 5 to 8 months of construction depending on size and whether it is detached or a conversion.

Does an ADU need its own utilities?

Not always. Junior ADUs and some conversions can share. Detached units often need a separate panel and sometimes a separate meter — we will tell you which applies before you commit.

Will an ADU raise my property taxes?

The ADU itself gets assessed and added to your assessment; your existing home is not reassessed. Talk to the county assessor for specifics on your property.

Can I rent it out?

In most cases yes, though short-term rental rules vary by jurisdiction and change often. Check current local ordinances before you build a business plan around nightly rentals.

Is a garage conversion cheaper than building new?

Usually, because the slab and some framing already exist. But not always — if the slab is not thick enough, the walls are not to code, or drainage has to be redone, the savings shrink fast. We check that during feasibility.
