LOCAL + LICENSED

Feasibility before promises

We review the address, existing structure, records, site constraints, utility questions, permit path, and intended use before a construction scope is finalized.

ONE GOAL / DIFFERENT PROPERTY PATHS

Start with the right ADU path for the property

Detached, attached, and converted-space projects share a purpose, but they do not share the same site work, structure, utility path, or permit questions.

Detached • Attached • Converted space

ADU AND CONVERSION SERVICES

Define the living unit before defining the finishes

The right scope starts with use, property conditions, legal constraints, and connected building systems, not a preset package or a square-foot promise.

Detached ADU planning and construction

Coordinate site placement, foundation, structure, envelope, utilities, energy measures, interiors, inspections, and site restoration.

Attached ADU and home expansion

Plan the connection to the existing home, structural changes, weatherproofing, fire separation, utilities, circulation, privacy, and finishes.

Garage conversion to living space

Review the existing garage, slab, framing, ceiling height, openings, egress, insulation, moisture, utilities, parking implications, and approved use.

Feasibility and preconstruction coordination

Organize records research, site review, design inputs, specialist needs, permit path, scope assumptions, allowances, and next decisions.

FIRST-PARTY PROJECT EVIDENCE / SACRAMENTO AREA

Two examples, with the evidence and limits stated clearly

01 · Completed Sacramento-area rear home addition
This completed residential addition shows exterior tie-ins, new openings, daylight, and finish coordination, the same tie-in work a garage conversion or ADU requires. Review our home addition service →

02 · Garage conversion design and visualization study
This first-party planning example shows how layout and 3D visualization can support early decisions before a construction scope is finalized. Review the garage conversion design study →

Both examples are provided to make our process easier to evaluate. ADU feasibility, permitting, scope, pricing, and construction remain property-specific.

A PROPERTY-SPECIFIC PROJECT SEQUENCE

How an ADU or garage conversion moves forward

The sequence changes with the site and jurisdiction, but the decision gates should remain visible from feasibility through final inspection.

Verify feasibility

Review the address, records, existing structures, site access, easements, setbacks, trees, utilities, parking questions, and intended use.

Coordinate design and approvals

Develop the measured scope, design documents, engineering when required, energy information, utility coordination, planning clearance, and building submittal.

Build and inspect

Protect the property; coordinate demolition or site work, structure, envelope, rough trades, insulation, drywall, finishes, equipment, fixtures, inspections, and corrections.

Close out the project

Resolve the punch list, collect applicable approvals and product information, review controls and maintenance, document completion, and confirm final agency steps.

Which Sacramento permitting authority applies?

A Sacramento mailing address does not by itself identify the permitting authority. First confirm whether the parcel is inside the City of Sacramento, in unincorporated Sacramento County, or within another incorporated city. The responsible jurisdiction controls the zoning, submittal, utility, fire, and inspection path.

Inside the City of Sacramento

Use the City ADU Resource Center, confirm City jurisdiction for the parcel, and follow the City's current Electronic Plan Check and building review process. Permit-ready resources still require site-specific review and approval.

Unincorporated Sacramento County

Use the County jurisdiction guidance to confirm that the parcel is in an unincorporated area, then follow Sacramento County planning and building requirements. Do not automatically apply City of Sacramento procedures.

Another incorporated city

If the property is in Citrus Heights, Elk Grove, Folsom, Galt, Isleton, Rancho Cordova, or another incorporated city, contact that city's planning and building department. Neither City of Sacramento nor unincorporated County procedures should be assumed to control the project.

The construction path also matters

A detached or attached ADU, a conversion ADU created from permitted existing space, non-ADU garage living space, and a garage replacement or major alteration can require different records, design, structural, energy, utility, parking, fire, and inspection decisions.

Site-specific approval still applies

Jurisdiction is the first checkpoint, not the approval. Confirm the legal parcel, existing records, setbacks, access, easements, trees, structure, fire separation, utilities, energy measures, and current agency requirements before scope or schedule promises are made.

DECISIONS TO MAKE BEFORE PLANS ARE FINAL

Solve the property questions before finish selections

Clarify long-term family use, rental goals, accessibility needs, privacy, bedrooms, storage, laundry, outdoor connection, and the relationship to the primary home.

Compare existing geometry, slab and framing conditions, ceiling height, openings, parking impact, utilities, expansion limits, site access, foundation work, and long-term flexibility.

Identify likely water, sewer, electrical, HVAC, gas when applicable, meter and panel conditions, trench routes, cleanouts, shutoffs, equipment clearances, and provider coordination.

Plan construction access, occupied-home protection, parking, material delivery, utility interruptions, neighbor conditions, emergency access, inspections, and site restoration.

Identify survey, engineering, agency corrections, service upgrades, windows, doors, cabinetry, appliances, plumbing fixtures, HVAC equipment, and finish selections that require early decisions.

Separate assumptions, allowances, exclusions, alternates, concealed-condition procedures, written approvals, payment milestones, inspection responsibility, and closeout documents.

OFFICIAL AND LOCAL PLANNING RESOURCES

Use the source that controls the next decision

State guidance explains the legal framework; the City and responsible agencies control the property-specific application, review, utility, and inspection path.

WHY US CONSTRUCTION

Design decisions stay connected to construction reality

Feasibility first. We separate verified property information from assumptions that still require agency, utility, or professional review.

Connected scope. Structure, envelope, kitchens, bathrooms, utilities, energy work, access, inspections, and finishes are coordinated as one project.

Written decisions. Scope, allowances, exclusions, alternates, changes, milestones, and closeout expectations are organized before they become field conflicts.

SACRAMENTO HOMEOWNER QUESTIONS

ADU and garage conversion FAQ

An ADU is an independent dwelling with permanent areas for living, sleeping, cooking, and sanitation. It may be detached, attached, or created by converting qualifying existing space. A garage conversion describes the construction path; it becomes an ADU only when the approved scope creates a legal dwelling that meets the applicable planning, building, energy, fire, utility, and inspection requirements.

No. Feasibility depends on the jurisdiction, legal status of the structure, setbacks and fire separation, ceiling and slab conditions, parking and access, utilities, energy compliance, windows and egress, protected trees, easements, and other property-specific constraints. The address and existing records should be reviewed before design promises are made.

Yes. The City of Sacramento lists garage conversions among projects that require a building permit, and ADU work also requires the applicable planning clearance and building review. All new submittals and resubmittals are handled through the City's Electronic Plan Check process. The exact path depends on the address and approved scope.

The City offers permit ready and preapproved ADU resources, but a plan still requires site-specific review and permitting. Lot conditions, utilities, setbacks, fire access, trees, grading, and the relationship to the existing home can require additional work or make a different design more appropriate.

The full calendar includes feasibility, records research, design, engineering when required, planning and building review, corrections, product decisions, construction, inspections, and closeout. Garage conversions often have less exterior construction than detached ADUs, but hidden conditions and utility upgrades can change the sequence. A reliable schedule is prepared only after the property and scope are reviewed.

Pricing depends on size, existing conditions, design and engineering, permit requirements, foundation and framing work, utilities, service upgrades, kitchens and bathrooms, energy measures, windows and doors, fire separation, access, finishes, and site work. We begin with a feasibility and scope review, then replace assumptions with measured information and a written proposal.

Emin prepared the page structure, official-source references, and homeowner decision flow. Umit Sahin reviewed the construction sequencing, contractor boundaries, permit checkpoints, utilities, inspections, change control, and closeout guidance. Property-specific design and code decisions remain with the responsible agencies and licensed professionals for the project.
