Garage-to-Bedroom Conversion Services in Pasadena, CA 


A garage-to-bedroom conversion in Pasadena creates additional sleeping space for growing families, home offices, or rental income opportunities while navigating strict building code requirements for egress windows, ceiling height, and fire safety. Pasadena Master ADU Builder designs practical, permit-ready conversions that maximize space through open floor plans, improve energy efficiency with spray foam insulation, dual-pane windows, and Title 24 compliance, and increase your home's livable square footage without the cost of ground-up construction. We handle architectural drawings showing closet placement, electrical outlets at code-required spacing, HVAC ductwork extensions or mini-split systems, flooring transitions from garage concrete slabs to engineered hardwood or carpet, and drywall installation over proper vapor barriers that prevent moisture issues.


We guide you through site assessment evaluating existing foundation integrity, wall framing capacity for insulation retrofits, and natural light opportunities, then manage design development, permit applications with the Pasadena building department, and construction coordination including egress window installation meeting 24-inch height and 5.7 square foot opening minimums, smoke detector and carbon monoxide alarm placement, electrical panel upgrades, and finish carpentry. Our experienced team handles plan check responses, schedules required building inspections for rough framing, insulation, and final walkthrough, and ensures construction details like fire-rated drywall between living spaces, proper ventilation, heating loads, and flooring underlayment meet all code requirements.

Garage-to-Bedroom Conversion Services in Pasadena


We transform underused garages into safe, code-compliant bedrooms that increase usable living space and property value. Our garage conversion ADU services focus covers layout planning, utility upgrades, permit handling, and finish choices tailored to Pasadena homes.

Expertise of Pasadena Master ADU Builder


We have extensive experience converting attached and detached garages across Pasadena neighborhoods. Our team evaluates foundation condition, existing framing, and roof integration on site to determine whether the garage requires structural reinforcement or only interior work.


We document required egress windows, ceiling height compliance, and insulation upgrades to meet California Title 24 and local Pasadena code requirements. We also audit existing electrical and plumbing to plan new circuits, outlets, and any nearby bathroom connections.


We keep an account of prior projects and client preferences to speed decision-making. That project history helps us recommend proven flooring, window, and HVAC solutions that perform well in local climate and seismic conditions.

Full-Service Project Management


We manage the entire conversion from initial site survey through final inspection and permit sign-off. Our project managers prepare packet-ready permit submissions, schedule inspections, and coordinate subcontractors so work proceeds on a clear timeline.


We provide a written scope, phased schedule, and line-item budget to each client. This account-based approach ensures transparency for costs like materials, labor, and permit fees and prevents surprise charges during construction.


We maintain daily logs and photo records during construction. These records allow us to quickly resolve issues, keep homeowners informed, and support warranty or post-completion service requests.

ADU Customization Options


We offer customizable design packages that address layout, storage, lighting, and HVAC choices. Clients can select built-in closets, Murphy beds, fold-down desks, or wall-mounted shelving to maximize small floor plans common in Pasadena bungalows.


We present finish palettes with specific materials and maintenance notes, such as engineered hardwood for durability, moisture-resistant drywall, and low-VOC paints. We also offer window options that meet egress rules while improving natural light and sound control.


We can integrate ductless mini-split systems or tie into an existing central system depending on efficiency goals. Our team prepares a comparative cost and performance table for each option to help clients make informed decisions.

Our Process for Converting Your Garage to a Bedroom


We outline the steps we take, the decisions you will make, and the approvals you will need. Expect site measurement, a custom design, permit processing, and a phased construction plan with clear milestones.

Initial Consultation and Needs Assessment


We begin with an on-site visit to measure the garage and document existing utilities. Our team records wall dimensions, ceiling height, floor slab condition, and locations of electrical panels and plumbing lines. We discuss intended use, number of occupants, and required features such as an en suite bathroom, closet space, HVAC, and soundproofing. We clarify budget ranges and timeline constraints at this stage. We provide a preliminary feasibility check against Pasadena zoning rules and property setbacks. If you want, we produce a short video walkthrough and annotated floor plan to confirm scope and priorities before design work starts.


Design and Planning Phase


We develop schematic plans that convert the garage footprint into a bedroom layout with clear circulation and natural light. Plans show door and window placement, closet sizing, and any structural modifications like removing or replacing the garage door with framing and glazing. We specify insulation, vapor barriers, flooring type, electrical circuits, lighting plan, and HVAC options. We include accessibility details if required and propose sound attenuation for shared walls. We offer a 3D model and site map overlays on request to visualize solar orientation and street access. We finalize construction drawings and a materials list that contractors will use for accurate bids.


Permitting and Local Regulations


We prepare complete permit-ready documents tailored to Pasadena Building and Safety requirements. Our packet includes floor plans, structural calculations, energy compliance forms, and any plumbing or mechanical schematics. We submit plans electronically and monitor review comments from the city. We coordinate revisions and resubmit until we receive approval. We handle application for inspections and schedule them to align with construction phases. If California ADU or local ordinances affect the conversion, we identify applicable exceptions or required upgrades and document them for the permit file.


Construction and Finishing Touches


We sequence work to minimize disruption and protect the rest of the house. First, we perform structural modifications and frame new walls, then we complete rough-in for electrical, plumbing, and HVAC. We insulate, install drywall, and apply finishes such as paint and flooring. We fit doors, windows, trim, and closet systems. We coordinate final inspections and correct punch list items promptly. We deliver a brief video walkthrough and digital map of electrical and plumbing locations for your records. We also provide warranties and maintenance guidance for installed systems.

  • How much does garage-to-bedroom conversion cost?

Adding a bathroom increases costs to $45,000-$75,000 including plumbing installation, fixtures, tile work, ventilation, and sewer connections. Premium finishes, extensive structural work, HVAC installation, or electrical panel upgrades add $10,000-$20,000 to total project costs including permits and inspections.

  • Do I need permits for garage-to-bedroom conversion?

    Yes, garage-to-bedroom conversion requires building permits from Pasadena Building & Safety Department including general construction permit, electrical permit for outlets and circuits, mechanical permit for HVAC if adding heating and cooling, and plumbing permit if installing bathroom. Permits ensure compliance with egress window requirements, insulation standards, structural modifications, fire safety codes, and electrical capacity. Pasadena Master ADU Builder handles all permit applications, plan submissions, inspection coordination, and code compliance verification throughout the conversion process.
