ADU Design, Permitting, Construction, and Financing in the Sacramento Area
Maruda Construction is a Sacramento-area contractor specializing in the full process of accessory dwelling unit (ADU) development — from initial feasibility through design, permitting, construction, and financing assistance. They operate as a single team across all phases, which is intended to reduce the handoffs and delays that often come with managing multiple contractors or consultants.
Their services cover detached ADU construction, including standard and premium configurations, as well as the coordination required to get a unit permitted and built in Sacramento-area jurisdictions. Maruda Construction positions itself as a full-service ADU builder for homeowners looking to add rental income, accommodate family members, or increase property value.
What the Process Looks Like
Maruda Construction begins each project with a feasibility visit — a 60 to 90 minute onsite meeting with the General Contractor. During this visit, homeowners receive:
- One to two siting concepts, provided as a photo overlay or sketch
- A parcel-specific permit and zoning checklist
- A realistic cost range and project timeline
- A one-page ROI summary with projected rent and cashflow estimate
Following the feasibility visit, a bankable cost estimate, permit roadmap, and ROI summary are typically delivered within five business days.
From there, the process moves through four main stages:
- Design — Permit-ready plans developed with architect and structural coordination
- Construction — Full site work, foundation, framing, MEP systems, and finishes
- Handover — Draw management, inspections, certificate of occupancy, and a handover packet including as-builts and warranties
- Financing assistance — Builder-led support to simplify loan packaging
A typical project timeline runs approximately four months from feasibility to occupancy, with the permitting phase taking up to eight weeks and construction around three and a half months, depending on scope and site complexity.
Typical Project Budgets
Maruda Construction provides the following general budget ranges for detached ADU builds:
- Standard ADU — 2 bed / 2 bath, approximately 746 sq ft: $230,000 – $245,000
- Premium ADU — 3 bed / 2 bath, 1,000+ sq ft: $260,000+
These figures are for detached ADUs. Final pricing is provided after the site visit and varies based on site complexity and utility work. Line-item estimates are available after the feasibility visit, and fixed-price or capped options may be available for defined scopes.
As a point of reference, one of their featured projects — a 746 sq ft detached ADU in Fair Oaks — involved full design, foundation, utilities, and finishes. Permits took approximately two months and the build took three and a half months, with a final cost in the $265,000 range.
Maruda Construction also assists with financing options for ADU projects. Having design, construction, and financing coordinated through one team is intended to reduce paperwork and support the underwriting process, as contractor-verified budgets can feed directly into the loan package. Financing is subject to borrower credit approval, property eligibility, appraisal, and underwriting, and its use is optional.
For homeowners in the Sacramento area considering an accessory dwelling unit — whether as a granny flat, in-law suite, backyard cottage, or income-generating rental unit — Maruda Construction offers a structured approach to managing the complexity of the ADU construction process from start to finish.
