ADU Construction in Pasadena

Planning a project in Pasadena, CA? An accessory dwelling unit is the biggest single upgrade most Pasadena homeowners can make to a lot: rental income, a place for parents or grown kids, or a home office that is actually separate from the house. We handle the whole job in-house, from the site survey and plans to permits, construction and final inspection.

Pasadena is about 14 miles east of our North Hollywood office, so our Southern California crews are on site quickly for estimates, inspections and the day-to-day work.

What's included

• Feasibility check of your Pasadena lot: setbacks, utilities, easements and access
• Custom or pre-approved floor plans, studio to two bedrooms
• Structural and Title 24 energy calculations
• Permit submittal and plan-check corrections with the building department
• Foundation, framing, roofing, plumbing, electrical and HVAC
• Kitchen, bath and finish work, through final inspection and certificate of occupancy

Building in Pasadena

Many Pasadena homes sit on hillside lots or in designated fire hazard severity zones. That can mean geotechnical review, retaining walls, and ignition-resistant materials under the California wildfire building standards. We plan for those requirements from the first site visit.

Building permits for Pasadena projects are issued by the City of Pasadena. California law requires local agencies to approve or deny a complete ADU application within 60 days, and owner occupancy is no longer required. We prepare the submittal so it is complete the first time.

What affects the price

• Detached new build versus attached or JADU
• Square footage and number of bedrooms
• Utility runs and whether the main panel or sewer lateral needs an upgrade
• Site access for equipment and the slope of the lot
• Finish level of the kitchen and bathroom

Every estimate is free, written and itemized. Call 844-975-5512 to schedule a visit.

Pasadena ADU Construction FAQ

How long does an ADU take to build in Pasadena?

Most detached ADUs take two to four months of design and permitting followed by four to six months of construction. Garage conversions and JADUs are usually faster. We give you a written schedule before you sign.

Can I rent out an ADU in Pasadena?

Yes. State law lets you rent an ADU long term. Short-term rental rules are set locally, so we confirm the current Pasadena rules during the feasibility check.

Do you handle the plans and permits?

Yes. Design, engineering, permit submittal and corrections are all part of our scope, so you deal with one company from start to finish.

Do you serve all of Pasadena?

Yes. We work throughout Pasadena and the surrounding Los Angeles County communities from our North Hollywood office. Call 844-975-5512 to schedule a free estimate.
