Second-Story Additions for Pasadena Homeowners
Second-story additions in Pasadena call for more caution than almost anywhere else in the region, because so many streets are defined by one-story Craftsman bungalows and historic character. Simply Construction assesses feasibility honestly, then manages engineering, reviews and construction under one contract when an upper floor makes sense.
Sometimes the best answer is a partial second story, or a ground-floor addition instead. We tell you which approach fits your house and street before you spend money on full design and engineering.
Local Knowledge
Second-Story Additions in Pasadena
In landmark districts such as Bungalow Heaven, where one-story bungalows set the scale of the street, a second story that changes the front profile of a house is difficult to reconcile with historic review. Where upper-floor space is possible, it usually takes the form of a partial second story toward the rear, set well back from the facade and kept below the dominant roofline so the house still reads as a bungalow from the sidewalk.
Outside historic districts, second stories are more common but still reviewed for massing, privacy and compatibility. On hillside lots in the overlay, height, size and neighborhood compatibility standards apply, and views from neighboring homes in Linda Vista and San Rafael Heights deserve early attention.
Structurally, many older Pasadena homes rest on raised foundations with cripple walls and modest footings. An engineer determines whether the existing foundation can carry a second floor, and the answer often includes new footings, shear walls, hold-downs and foundation bolting. The Sierra Madre fault zone along the base of the San Gabriel Mountains is a reminder of why that work matters.
What's Included
What a Pasadena Second-Story Project Covers
- Feasibility review of historic status, hillside overlay rules and floor area
- Street-view sketches showing how the upper floor sits behind the original roofline
- Foundation bolting, cripple wall bracing and new footings as the engineer specifies
- Design or historic review submittals prepared and tracked by our team
- A stair location chosen to leave original built-ins, beams and fireplaces undisturbed
- Protection of original interior woodwork and finishes during framing and roofing
- Upper-floor framing, a new roof, mechanical and electrical extensions and final inspection

Planning Considerations
Second-Story Decisions for Pasadena Homes
Partial second stories and attic space
Many Pasadena homes, particularly larger Craftsman and revival houses, have roof forms that can accommodate living space tucked under the roof or a modest upper floor at the rear. These approaches add bedrooms or a primary suite while keeping the street profile largely intact. They often make review more manageable and reduce the structural demands placed on the original foundation.
Engineering an older house for a new floor
Adding weight to an older raised-foundation house also increases the earthquake forces acting on it. The engineer's design ties the new floor to the old, carries loads down to new or strengthened footings, and adds shear walls where the existing walls lack capacity. We price that work in the first phase so it never surprises you during construction.
Protecting original interiors
Craftsman interiors with original woodwork, built-ins and plaster are difficult to replace. During a second-story project, we protect or temporarily remove vulnerable elements, such as beamed ceilings beneath the new floor or built-in cabinetry near the new stair, and we route new ductwork and wiring to avoid cutting through the rooms that give the house its character.
Why Choose Us
Why Pasadena Homeowners Choose Simply Construction
Licensed, Bonded and Easy to Verify
Simply Construction inc. is a licensed California general contractor, CSLB [CSLB LICENSE # PLACEHOLDER].

We encourage every Pasadena homeowner to do exactly that before signing with anyone, including us.
Straight Answers on Feasibility
Some lots cannot fit the project an owner has in mind. We check zoning, setbacks, height limits, easements, slope and utility capacity early, and we tell you plainly what is achievable before you spend money on full drawings. When state law opens a path that the local code seems to block, as ADU and SB 9 rules often do, we explain how it applies to your property.
Care for Your Street and Your Neighbors
Large projects happen next door to people who live there. We plan staging, dumpster placement, deliveries and working hours around Pasadena rules, keep the site secured at the end of each day, and give you notice before loud or disruptive phases such as demolition, concrete pours or crane lifts, so you can give your neighbors a heads-up too.

FAQ
Second-Story Additions in Pasadena: Common Questions
Can I add a second story to a house in a Pasadena landmark district?
It depends on the house and the district. Full second stories that change the front profile of a one-story historic home are difficult to approve. A partial upper floor at the rear, set back and kept below the main roofline, has a better chance. We assess your home and district before recommending any design.
Will a second story affect my home's historic standing?
It can. A large upper floor on a designated or contributing house may be found incompatible, and changes to character-defining features can affect how the house is viewed within its district. That is why we engage with historic review early and favor designs that keep the original roofline and front facade intact.
Does the hillside overlay affect second-story additions?
Yes, if your lot is within it. The overlay addresses height, size and neighborhood compatibility for hillside properties, so a second story is evaluated against those standards and the views and privacy of nearby homes. We check whether the overlay applies at the first site visit.
