Home Renovation & ADU Contractor
Aldridge Construction is your Gilroy-based design–build partner for stress-free remodels, additions, and ADUs. With one accountable team managing planning, permitting, engineering, and construction, your scope, schedule, and budget stay in sync from the first sketch to the final walkthrough.
Because we work in Gilroy week in, week out, we move efficiently through GO Permit submittals and inspections, and leverage the City’s pre-approved ADU plans when they’re a fit, to help compress review timelines. Expect clean, code-ready drawings, transparent pricing, and durable craftsmanship that stands up for years.
Our Home Renovation and ADU Services
From early feasibility to the final punch list, we package remodels, additions, and ADUs/JADUs so approvals move quickly and construction stays efficient. Below is what we build—and how we keep City and County steps straightforward.
Home Renovations & Additions
Enhance your home with upgrades that improve comfort, flow, and long-term value.
- Kitchen & bath remodels: Smarter layouts, durable finishes, balanced lighting/ventilation, and code-compliant MEP work tuned for today’s standards.
- Interior upgrades: Flooring, trim, built-ins, and storage, planned to complement your home’s character while improving function.
- Whole-home updates: Insulation, HVAC/heat-pump options, efficient lighting, and window replacements planned to meet Title 24 energy requirements.
- Window/door improvements: Better egress, thermal comfort, and envelope performance with correct flashing details and inspection sequencing.
- Exterior refresh: Siding and roofing replacements using ventilated assemblies and a documented CALGreen waste-management approach.
- Structural reconfiguration: Wider openings, beams, and lateral upgrades engineered for safety and verified in plan check.
- Room & second-story additions: Full plan sets with structural calculations and energy forms included for a clean review path.
Accessory Dwelling Units (ADUs)
Create a guest home, caregiver suite, or long-term rental that fits your lot and budget.
- Detached, attached, and over-garage ADUs: Designs tailored to your architecture, utility layout, and site access for smooth permitting and build.
- Garage conversions: Structural, fire-separation, and energy details are drawn and specified so field work passes inspections the first time.
- JADUs (up to 500 sf) inside the main home: Dedicated exterior entry and an efficiency kitchen, plus the owner-occupancy deed restriction required for JADUs.
- Front-loaded feasibility: We verify setbacks, height, parking, utilities, and any local hazards (e.g., Calaveras Fault considerations) before we draw.
- Required reports & reviews: We coordinate geotech, structural, and any environmental submittals when the site or scope triggers them.
- Energy-ready plans: Title 24 modeling and CALGreen documentation are bundled so plan check proceeds without avoidable rework.
Aldridge Construction stays current with City of Hollister requirements and California energy/green codes. We provide permit-ready submittals so your ADU or JADU is comfortable, efficient, and approvable.
ADU Requirements in Hollister (What’s Allowed)
Hollister implements state ADU law with local standards for size, height, setbacks, parking, and rentals. We confirm parcel-specific rules at feasibility and reflect them in drawings, notes, and your site plan to reduce corrections and keep approvals ministerial wherever possible.
Size & Height
State law guarantees at least 850 sq ft (studio/1-bed) or 1,000 sq ft (2+ beds) for an attached or detached ADU; local maximums then apply based on zoning and lot standards. Typical detached heights begin at 16 ft, with additional allowances in certain contexts; we verify what applies to your parcel during intake.
Setbacks & Fire-Safety
Most detached ADUs observe minimum 4-ft side and rear setbacks under state preemption, while attached units track the base zone with state minimums preserved. Fire sprinklers are only required if the primary dwelling requires them; where wildfire or WUI notes apply, we integrate hardening measures and defensible-space details into your plans.
Utilities & Separate Entry
ADUs must have working water, sewer, and electric/gas; for some conversions, separate utility connections and capacity charges may be limited by state law. Your ADU needs a separate exterior entrance, and JADUs may retain an interior connection plus an owner-occupancy deed restriction, requirements we document and record as part of your permit path.
Parking & Rental Rules
At most one space per ADU/bedroom can be required, and tandem or driveway spaces typically count; multiple exemptions eliminate parking (e.g., conversion ADUs or proximity to transit). Hollister’s deed restriction prohibits rentals under 30 days for the primary and ADU; we prepare and record the City’s form before final.

Permits & Compliance We Handle
Aldridge Construction manages the paperwork and back-and-forth so you can focus on the build—not bureaucracy.
ADU Submittal (City of Hollister)
ADUs and JADUs are ministerially reviewed with a building permit (no hearing). We prepare full sets, site, floor, elevations, structural as needed, plus Title 24/CALGreen, submit via Accela, track corrections, and schedule inspections. If in the County with a matching pre-approved plan, we use that path to save design time.
Water & Environmental
Adding fixtures or bedrooms may require utility confirmations. We handle sewer notes with the City/Sunnyslope Water District and track San Benito’s regional role in Hollister. ADUs under 750 sq ft are exempt from fees, while larger units may be charged proportionately, as shown in your budget.
Renovation & Addition Permits
For remodels and additions, we assemble code-true drawings, structural calculations, and required notes (e.g., WUI/fire), then bundle energy and green-building documents so plan check proceeds cleanly, reducing rework and keeping review cycles predictable.
Coastal & Historic Overlays
Hollister is inland, so California Coastal Commission permits do not apply. If your parcel carries historic-resource considerations or fault-zone constraints (e.g., Calaveras Fault), we flag them early, fold objective standards or geologic steps into design, and keep the process objective and approvable.
Our Design–Build Process
Our integrated approach keeps design, approvals, and construction on one coordinated path—saving time, preventing scope drift, and protecting your budget.
Consultation & Site Feasibility
We begin with goals, timelines, and a budget checkpoint, then study zoning, setbacks, height limits, access, utility paths, tree/grade constraints, and any hazard overlays or deed-restriction steps. For ADUs, we verify size, height, parking, and deed requirements, so drawings start on solid ground.
Concept Design & Budget
You’ll compare clear layout options with value-engineering notes. We specify systems and assemblies that pass Title 24 and CALGreen without redesign at plan check, and we provide an itemized estimate with steerable allowances so finishes and features match your priorities.
Permitting & Approvals
We prepare forms, upload via Accela Citizen Access, respond to plan-check comments, and sequence inspections, while coordinating utility/fire sign-offs and sending clear status updates. For County parcels, we recommend pre-approved ADU plan sets when they align with your program, site, and timeline.
Construction
Dedicated project management coordinates trades, protects the work zone, and maintains a tidy, safe jobsite. Quality checkpoints at each milestone keep work on spec and inspections smooth, with assemblies detailed for durability and long-term performance.
