Carmichael lots are older and more layered than they look
Most Carmichael housing dates to the 1950s-1970s build-out around Fair Oaks Boulevard and Walnut Avenue. Backyards have had several owners and several rounds of landscaping — original gunite pool, added patio, second patio, sheds, garden walls, sometimes a slab where a workshop used to be. ADU prep here usually means peeling back layers we did not necessarily know were there until we started. Pool removal is the most common single-line item on Carmichael ADU jobs.
Common Carmichael ADU prep scope
- Pool removal — partial or full depending on whether ADU sits over the footprint
- Layered patio and flatwork removal
- Shed, garden wall, and outbuilding demolition
- Mature canopy work coordinated with Sacramento County tree review
- Rough grade and compaction on the pad envelope
- Drainage redirection where old swales no longer work
Pool first, then everything else
On a Carmichael lot where the planned ADU sits over a former pool, we usually do pool removal as the first phase of the same mobilization. Full removal with engineered backfill and compaction is the structurally safer answer when an ADU slab will sit over the area. Doing it as one phase saves a second mobilization and lets the same crew transition from pool removal to pad shaping without losing a week.
Cost variables on a Carmichael ADU prep

| Layered patios and walkways | +$2,000-$5,000 | Very common on older Carmichael lots |
| Protected mature trees | Arborist + county review | Sacramento County oak ordinance applies |
| Outbuilding count | +$2,500-$7,500 each | Sheds, garden sheds, hobby slabs |
| Buried surprises | Photo + change order | Old plumbing, drylines, original irrigation |

Frequently asked questions
- Is pool removal typically part of a Carmichael ADU job?
- Yes — more than half the ADU prep calls we get from Carmichael involve a pool that is sitting in or near the planned footprint. Full removal with engineered backfill is the cleaner path when an ADU slab will sit over the area.
- Who pulls demolition and grading permits here?
- Sacramento County. Carmichael is unincorporated, so demolition, pool, and grading permits all run through building.saccounty.gov rather than a city department.
- How long does Carmichael ADU site prep take?
- Five to ten working days on site is typical when pool removal is involved. Simpler clearing-only jobs are faster. Permit timing and tree review run in parallel.
- Can the same crew handle pool removal and ADU pad prep?
- Yes, and it usually saves time and money. Doing both phases under one mobilization keeps the equipment on site and lets the pad shaping pick up right after backfill and compaction are signed off.
