What Sacramento ADU lots usually look like
Most Sacramento ADU jobs land on infill parcels in Curtis Park, Tahoe Park, Land Park, Oak Park, East Sac, and the older grid north of Broadway. Those lots typically have a detached garage off the alley, a mature tree or two with protected canopy, a 36-42 inch side gate, and sometimes a midcentury pool that has not been swum in for a decade. The pad envelope is usually 600-1,200 square feet behind the house — small footprint, but tight conditions for equipment and haul-off.
Common Sacramento ADU prep scope
- Detached garage or carport demolition (alley-accessed lots especially)
- Old gunite or concrete pool removal where the ADU footprint overlaps the shell
- Mature tree coordination — Sacramento heritage-tree review before any canopy work
- Tight side-yard access planning when alley access is blocked
- Concrete patio, walkway, and flatwork removal inside the build envelope
- Rough grade, compaction, and drainage shaping toward the alley or street
- Utility trench prep for the builder's sub-panel, water, and sewer lateral
Access matters more here than people expect
On older central-Sacramento lots, equipment access is the first thing we walk. If the property has an alley, most demo and haul-off can run from the back — which is faster and protects the front yard. If alley access is blocked or there isn't one, everything has to thread the side yard, and a 36-inch gate limits us to skid steers and mini-excavators. We confirm the access plan before quoting because it drives the equipment list, the haul-off route, and the crew size.
Cost variables on a Sacramento ADU site prep
| Variable | Effect on Scope | Notes |
|---|---|---|
| Alley access vs side-yard only | Lower or higher cost | Alley = larger equipment, faster haul. Side yard = mini-excavator only. |
| Existing detached garage | +$3,000-$8,000 | Most older Sacramento infill lots have one; slab removal scoped separately |
| Pool inside ADU footprint | +$10,000-$20,000 | Usually requires full removal with documented compaction |
| Heritage / protected tree in the work zone | Permit + arborist time | City review can add 2-4 weeks before clearing |
| Concrete patio + walkway scope | +$1,500-$4,500 | Common around midcentury Sacramento homes |
Handing off to the foundation crew
- We leave the pad rough-graded with documented compaction notes
- Drainage routed off the pad in the direction the engineer's plan calls for
- Utility trench paths cleared and accessible to the builder's sub crews
- Debris hauled, work area broom-clean, and access path restored
- Photos of subgrade and any buried surprises (old footings, pipes, drylines) given to the GC
Frequently asked questions
- How long does ADU site prep take on a Sacramento infill lot?
- Most jobs run three to seven working days on site once we mobilize. Permit timing, mature tree review, and pool removal scope are usually the longer items on the calendar — start those conversations before the foundation crew is booked.
- Do you handle pool removal when an ADU will sit over the footprint?
- Yes. When the planned ADU footprint crosses a former pool, full removal with engineered backfill and compaction documentation is the safer path. A partial fill-in is rarely structurally acceptable under an ADU slab in Sacramento.
- Can you work on a Sacramento lot with a 36-inch side gate?
- Yes, with mini-excavators, skid steers, and hand tools. Tight access lots take longer and cost more than alley-accessed lots, but they are routine for us in central Sacramento. We walk the access path before quoting so the equipment plan is honest.
- Does Sacramento have a tree ordinance that affects ADU clearing?
- Yes. The City of Sacramento has a heritage tree ordinance and additional rules for trees on private property over a certain trunk diameter. We flag protected trees during the walk and coordinate review before any canopy work happens.
- Are you the GC for the ADU?
- No. We are site prep specialists — clearing, demolition, grading, and pad readiness — and we hand the site off to your ADU builder or general contractor. Scope and final pad spec depend on your architect's plan.
