What types of ADU construction does Burnette Construction build in Antelope, CA?

Burnette Construction designs and builds all categories of Accessory Dwelling Units in Antelope and Sacramento County. Our core services include custom detached backyard cottages, attached ADU room additions, garage conversions (turning attached or detached garages into legal living suites), basement conversion ADUs, junior ADUs (JADUs), two-story accessory units, and prefab modular ADU installations. Each project is tailored to the homeowner's property layout, zoning setbacks, and living objectives.

How long does it take to design, permit, and construct an ADU in Sacramento County?

The timeline typically spans two main phases: preconstruction (design, engineering, Title 24 energy calculations, and Sacramento County plan check review), which takes between 8 and 14 weeks; followed by active construction, which ranges from 3 to 5 months for garage conversions and 5 to 8 months for custom ground-up detached ADUs. Burnette Construction expedites the permit submission process directly through Sacramento County Building and Planning to prevent administrative lag.

What are the California zoning setback and size rules for building an ADU in Antelope?

Under California state law (Gov. Code § 65852.2) and Sacramento County ordinances, homeowners are permitted to build detached ADUs up to 1,200 square feet with standard 4-foot rear and side yard property setbacks. Existing legally established garages converted to ADUs can maintain their current zero-foot setbacks. Detached ADUs are allowed minimum heights of 16 to 18 feet (and up to 25 feet for two-story builds or within half a mile of major transit corridors).

What is involved in converting an existing garage into a legal ADU?

A compliant garage conversion requires sealing the concrete foundation slab with an epoxy vapor barrier to block moisture, installing R-15 to R-21 wall and R-30 to R-38 ceiling insulation, applying closed-cell spray foam at headers to eliminate thermal bridging, cutting IRC Section R310 compliant egress windows (minimum 5.7 sq ft net opening), routing PEX-A water and ABS sewer lines, upgrading electrical service, and installing high-efficiency ductless mini-split HVAC units for Title 24 compliance.

Does Burnette Construction handle architectural drafting, engineering, and permits?

Yes. Burnette Construction is a full-service design-build general contractor. We handle site feasibility evaluation, custom architectural floor plans, 3D elevations, structural engineering calculations for Zone D1 seismic conditions on native expansive clay soils, California Title 24 Part 6 energy documentation, and complete permit acquisition through Sacramento County before mobilizing construction crews.

Can an attached or detached ADU be built as a two-story unit in Antelope?

Yes. For properties where yard size or lot coverage constraints limit ground-level building footprints, two-story attached or detached ADUs provide optimal square footage. Burnette Construction assesses foundation capacity, designs engineered underpinning piers anchored deep in clay soil zones, calculates CBC Section 2308 load paths, and strategically positions windows to preserve privacy for adjacent neighbors.

What payment methods does Burnette Construction accept for construction projects?

Burnette Construction accepts major payment cards including credit cards and debit cards. All project billings adhere strictly to California Contractors State License Board (CSLB) progress milestone billing schedules, with transparent written proposals, documented change orders, and zero hidden fees. We also partner with Acorn Finance to offer flexible project financing solutions for qualifying homeowners.

Is Burnette Construction licensed, bonded, and insured in California?

Yes. Burnette Construction is fully licensed by the California Contractors State License Board under Class B General Building Contractor License #1084547. We maintain full worker's compensation coverage and carry over $1,000,000 in general liability insurance. The company is veteran-owned and managed by USMC veteran Christian Perry (Owner & Responsible Managing Officer), holding an A+ rating with the Better Business Bureau.

What is the difference between an Attached ADU and a Detached Backyard Cottage?

An Attached ADU shares at least one common wall with the primary dwelling, utilizing shared structural tie-ins, integrated fire separation walls, and often tied directly into the main roofline. A Detached ADU is an independent, freestanding structure built in the backyard with its own foundation, separate perimeter setbacks, and independent utility trenching, providing maximum tenant privacy and acoustic separation.

How much does it cost to build an ADU in Antelope, California?

The cost to build an ADU in Antelope, CA typically ranges from $90,000 to $160,000 for a garage conversion, $150,000 to $280,000 for an attached ADU addition, and $200,000 to $380,000+ for a custom ground-up detached backyard home, depending on total square footage, architectural complexity, utility trenching distances, and chosen interior finish levels. Burnette Construction offers free on-site consultations and transparent cost calculations. Call (916) 821-9353 or visit 8100 Otium Way, Antelope, CA 95843 for a tailored quote.
