Freestanding, shares nothing
A detached unit is its own building
What makes a detached ADU worth the money is the same thing that makes it the bigger job: it shares nothing with your house. Own slab. Own framing. Own roof. On a flat Cordova Meadows lot we set a 612 sq ft single-story unit at the back of the yard, and because it stood completely free we could turn the living room windows toward the morning sun instead of staring at the side fence. That's the flexibility detached gives you that nothing else does. The price of it is a second foundation, a separate roof system, and a longer haul for materials from the street to the back. We map all of that before you sign anything.

City of Rancho Cordova permits
The Rancho Cordova permit path
Rancho Cordova incorporated in 2003. It's its own city now, so your detached ADU permit runs through the City of Rancho Cordova planning and building counter — not Sacramento County. That matters, and here's the good news: the City counter is one of the smoother, faster ADU desks in the whole metro. State law made the review ministerial, which means a complete, code-compliant set has to get issued. We submit a full package — site plan, floor plan, elevations, structural, Title-24, the MEP sheets, and SMUD service coordination. Clean first submissions on detached units have been turning around quick here. Submit something thin and you'll burn correction cycles you never needed.

Getting materials and power to the back
Everything that builds a detached unit has to physically reach the backyard. Most of Rancho Cordova helps you here — the lots are flat and easy to build on, which is half the battle on a detached job. On the older north side, in Cordova Meadows or Cordova Village near the old Mather field and Aerojet, the 1950s-60s tracts have decent side yards but aging infrastructure. Power runs through SMUD, not PG&E. The new meter, any panel work, the service drop — all SMUD's process and timeline. Those older homes often carry a 100-amp panel that's full, so a second dwelling means an upgrade. We measure gate width and side-yard clearance on the first visit and start SMUD early.

What the number actually is
What a detached ADU costs here
I'll give you a range, then tell you why ranges lie a little. A 600-ish sq ft one-bed detached unit with sensible mid-grade finishes generally lands around $238K to $298K all-in in Rancho Cordova. Push to a 1,000-plus sq ft two-bedroom with nicer cabinetry and fully separate utilities and you're closer to $360K to $450K. The honest caveat: detached carries its own foundation and its own roof, so it rarely pencils cheaper than converting an existing garage — if budget is the only driver, conversion wins. The flat terrain helps your number here, and on the older north side the savings are real. What moves it most is the finish package and your panel. We walk the yard, then hand you a fixed price.

Service areas
Where we build
Headquartered in the Greater Sacramento Area and serving homeowners from the Sierra foothills down through the Bay Area. Don't see your city? We probably still get there — just ask.
The most common things Sacramento homeowners ask before starting an ADU project.
Through the City of Rancho Cordova. The city incorporated back in 2003, so it runs its own planning and building department — your detached ADU permit goes to the City counter, not Sacramento County. This trips up homeowners who assume anything in the county runs through one office downtown. The City has its own ADU submittal requirements, its own fee schedule, and its own portal. The upside: that counter has a reputation as one of the smoother, faster ADU desks in the metro, so a clean set tends to move quickly. We confirm your parcel sits inside city limits before we draw a single sheet.
For a complete, code-compliant set on a standard detached unit, first plan-check comments from the City of Rancho Cordova come back fast by metro standards — often a few weeks, usually with one correction cycle before issuance. The City counter moves quicker than a lot of jurisdictions around here. Total pre-construction — signed contract to permit in hand — normally runs 8-11 weeks once you fold in design and structural engineering. The single biggest variable is submittal quality. A thin set triggers extra correction rounds, and three rounds of back-and-forth eats more calendar than any counter queue.
SMUD — the Sacramento Municipal Utility District — not PG&E. All of Rancho Cordova sits in SMUD territory. So the service drop for your detached ADU, any panel upgrade, and the new meter all go through SMUD's application process, which has its own rules and its own timeline. If your main panel is near capacity — common on the older north-side homes in Cordova Meadows and Cordova Village that still carry original 100-amp service — you're often looking at a $4K-$8K upgrade before the unit can be energized. We engage SMUD early, while the foundation cures, so the meter isn't the last thing holding up your final.
Because you're pouring a brand-new foundation and framing a brand-new roof, plus all the exterior walls, siding, and weatherproofing of a standalone building. A garage conversion reuses a slab and a roof that already exist. On a Rancho Cordova lot that structural difference alone is often $42K to $70K for a 600 sq ft unit. Detached buys you a freestanding home you can place and orient anywhere the setbacks allow, with no shared wall to your house. But if the lowest possible price is the goal, a conversion will almost always beat it — and on the older north side, where garages are plentiful, conversion is worth a real look.
Not necessarily. State law lets a detached ADU under 750 sq ft keep shared utilities with the main house, which dodges thousands in separate-connection fees. Above 750 sq ft a separate water connection is more likely to be required. For a unit you plan to rent long-term, a separate SMUD meter is usually worth it so the tenant pays the electric directly. On the older Cordova Meadows and Cordova Village homes, the existing sewer lateral is often aging — if it's tired, we plan around it so the new unit isn't tied to a line that's about to fail. We design the utility plan around how you intend to use the unit.
Usually yes. The state floor is 4-foot side and rear setbacks for a detached ADU, which opens up even modest lots. The older north-side tracts near Mather and Aerojet sit on flat lots with decent side yards, so fit is rarely the problem there. The newer south-side neighborhoods off Highway 50 — Anatolia, Sunridge, Stonecreek, Capital Village, The Preserve — have bigger homes on more modest yards, so the footprint gets planned more carefully. Everything in Rancho Cordova is flat, which makes the build easier once it fits. We measure all of it on the first visit and show you what actually works before you commit.
On the south side, often yes. The master-planned neighborhoods off Highway 50 — Anatolia, Sunridge, Stonecreek, Capital Village, The Preserve — frequently come with an HOA that has architectural design review, so siding, roof color, and how the unit reads from the street may need approval on top of the City permit. State law caps how far an HOA can go — it can't ban an ADU outright — but it can impose reasonable aesthetic standards. Many of these areas also carry Mello-Roos special taxes, which don't block the ADU but are worth understanding as part of your carrying cost. The older north-side neighborhoods generally have no HOA at all. We check your CC&Rs early.
Depends on size, finish, and which side of the city you're on, but a finished detached one-bedroom in Rancho Cordova generally rents in the $1,750-$2,500 a month range as of 2025-2026. This is an affordable-to-mid market, so rents sit a touch below the pricier Placer County suburbs but the construction cost is lower too, which helps the math. A two-bedroom in a newer south-side area near Sunridge or Anatolia sits at the top of that range. The White Rock Road corridor and the proximity to the Highway 50 job centers keep tenant demand steady. Detached units rent fast because tenants get real privacy and their own entrance.
Generally no — and that's a genuine advantage here. The terrain across Rancho Cordova is flat, which keeps the foundation simple and the access straightforward. You don't get the slope work or the stepped foundations that some hillier parts of the region force on you. The main thing we watch on the older north side is aging infrastructure: full 100-amp panels and tired sewer laterals in the 1950s-60s tracts. On the newer south side, the lots are clean and the soil is predictable, the constraint there is the smaller yard and the HOA. Flat ground plus a fast City counter is a good combination for a detached build.
Yes — the older north side in Cordova Meadows, Cordova Village, and the tracts near Mather and the Aerojet area, plus the newer south side off Highway 50 in Anatolia, Sunridge, Stonecreek, Capital Village, and The Preserve, and along the White Rock Road corridor. Each area has its own character: the north side brings flat, affordable lots with aging 100-amp panels and older sewer laterals, while the south side brings bigger master-planned homes on modest yards with HOAs and Mello-Roos. Rancho Cordova is about 15 minutes east of our Sacramento home base, well inside our core service area, so we know what the City flags before it flags it.

Building a Detached ADU in Rancho Cordova — A Straight Guide for Sacramento County Homeowners
A detached ADU is the version most Rancho Cordova homeowners picture: a small, freestanding home with its own foundation, its own roof, and its own front door, fully independent of the main house. It's also the version with the most moving parts. This guide is about building one inside the City of Rancho Cordova — the permit counter, the SMUD service rules, the split between the older north side and the newer south side, and the real 2025-2026 numbers. We build these for a living, so most of what follows is what we'd tell a neighbor over the fence.
01Section
What "detached" actually means here
Detached means freestanding. The unit doesn't touch your house — its own slab or stem-wall foundation, its own roof structure, four of its own exterior walls. That's the line separating it from an attached ADU, which shares at least one wall with the main home, and from a garage conversion, which reuses an existing shell. All three are legitimate ADUs under California law. They just build, cost, and live differently.
The appeal of detached is independence. Because it stands alone, we place it where the lot wants it and orient it for light and privacy rather than locking it to the geometry of your house. A tenant or family member gets a genuinely separate dwelling — their own entrance off the side yard, their own outdoor space, no footsteps overhead. On a flat Rancho Cordova lot, a detached unit at the back of the yard reads as a small home of its own rather than an add-on bolted to the house.
