Adding a room, a second story, or a new bathroom in Maywood means working with lots that run 2,500 to 3,500 square feet and homes built between the 1920s and 1950s. That combination rarely leaves room for a standard detached addition. Seedling ADU Pasadena designs additions that fit Maywood’s narrow lots and older framing, and every project starts with a written price before any work begins. If you’re planning a garage addition, bathroom addition, or full second-story build, call (626) 657-5461 for a free estimate. We schedule crews locally and answer the phone with a live person around the clock.
Why Seedling ADU Pasadena Is Maywood’s Preferred Home Addition Contractor Company

Maywood homeowners call us because we understand what their houses actually are: small single-story bungalows on tiny lots, many with wood-frame construction and limited existing floor area. That housing stock rewards attached designs, not sprawling detached builds. Our Home Addition Contractor team has worked on homes throughout Maywood, including the blocks near Pine Avenue and the residential streets running east of Atlantic Boulevard. Those jobs taught us to check lot width before sketching anything. A standard 20-foot-wide detached addition often violates side setback requirements on Maywood’s narrow parcels, so we plan attached bump-outs, second-story additions over existing footprints, and garage conversions that preserve every usable inch.
Ben Ortega leads our crews and personally reviews each Maywood project before we submit plans. That matters when a 1930s bungalow hides knob-and-tube wiring or undersized ceiling joists behind plaster walls. We write allowances for those discoveries into the contract before demolition starts, then price any additional surprises in writing and get your approval before we touch a stud. No one in Maywood should watch a remodel quote balloon because a contractor skipped the inspection step. We don’t skip it.
Every crew member is background-checked, uniformed, and held to the Cedarwell Care Promise: shoe covers and drop cloths inside your home, pet-safe products where there is a choice, and a photo of the clean-up before we leave your Maywood property each day. Families with kids and pets know exactly who is walking through the door. And if something is not done right, our 365-Day Done Right Promise covers it, in writing.
Garage Addition Contractors in Maywood
Garage Addition Contractors in Maywood do more than pour concrete and frame walls. Most of our garage addition work here starts with a structural evaluation, because Maywood’s older garages were built as storage, not living space. We check the slab thickness, the existing footings, the roof framing, and whether the walls can carry the load of a new room above them. A typical garage addition in Maywood runs $80,000 to $180,000 depending on whether you’re converting the existing footprint, adding living space above it, or extending outward into the side yard.
Conversion With Parking Kept
Maywood enforces parking replacement rules on garage conversions. If you turn a garage into living space, the city may require you to provide a covered parking spot elsewhere on the lot. On a 3,000 square foot Maywood lot, that often means a compact carport tucked along the side or a tandem parking arrangement. We review the parking requirement before you commit to demolition, not after, so your plans don’t stall at the permit counter.
Adding A Second Story Over The Garage
When a side yard won’t fit an addition, going up over the existing garage often works. We verify the garage walls and footings can support a second floor, then design the stair placement inside the home’s existing footprint. This strategy keeps the lot’s outdoor space intact and avoids side setback problems entirely. A second-story addition over a garage in Maywood typically runs $150,000 to $280,000.
Bathroom Addition Contractor in Maywood

A Bathroom Addition Contractor in Maywood faces a specific challenge: the city’s small bungalows were built with one bathroom, and adding a second one means finding space without expanding the footprint. We usually locate new bathrooms adjacent to existing plumbing walls, above the kitchen or laundry, or inside a converted rear porch. A full bathroom addition in Maywood runs $35,000 to $75,000 depending on whether we’re adding a three-quarter bath inside existing square footage or building a new wet wall into an addition. A half-bath addition runs $18,000 to $35,000.
Working Inside The Existing Footprint
On a 2,800 square foot Maywood lot, we often convert a walk-in closet, a pantry, or the back corner of a primary bedroom into a new bathroom. That keeps the project a remodel rather than an addition, which simplifies permitting and keeps costs down. We match the existing floor level, route drainage to the nearest stack, and run a dedicated exhaust fan so moisture doesn’t sit in an older wood-framed wall.
Bathroom Inside A New Addition
When a Maywood family adds a primary suite or a rear family room, a bathroom is usually part of the plan. We run new supply lines and a separate drain line, insulate the exterior wall for Maywood’s cool wet winters, and waterproof the shower pan and surround before tile goes in. Every bathroom job gets a written line-item price before work starts, so you know the cost of fixtures, tile, plumbing, and labor separately.
Trusted Brands We Service in Maywood
Seedling ADU Pasadena works with the prefab and modular brands Maywood homeowners research before they call anyone. We offer hands-on support for Cover, Dvele, and Boxabl units, helping you select the right model for your lot width and setback limits. A Boxabl or Cover unit can be a strong fit for Maywood’s compact parcels when designed as an attached addition rather than a standalone structure. We also use James Hardie siding and trim on framed additions to handle Maywood’s seasonal rain and keep maintenance down. Because we stock ordering access and coordinate directly with these manufacturers, our Maywood customers avoid the multi-month delays that plague independent buyers.
Common Home Addition Contractor Problems We See in Maywood Homes
- Side setback rejection. A standard 20-foot-wide detached addition fails Maywood’s side setback rules on most lots under 3,500 square feet. We verify lot width against the city’s current zoning before we ever sketch a plan, saving you design fees and permit resubmissions.
- Knob-and-tube wiring and undersized framing. Homes built in the 1920s through 1940s in Maywood frequently hide outdated wiring and 2×4 joists that were never meant to carry modern loads. We open the walls with an inspection-first approach and write material allowances into the contract before demolition.
- Parking replacement surprises. Converting a garage triggers Maywood’s parking replacement rules, and discovering that after demolition has already started is expensive. We confirm the parking obligation during the planning phase and design a compliant carport or tandem space.
- Flat-roof ponding and water intrusion. Many Maywood homes have flat or low-slope roofs that pond water during winter rains. When we open a wall for an addition, we check the roof drainage and waterproofing at the connection point so the new work doesn’t inherit old leaks.

FAQs About Home Addition Contractor in Maywood
On a 3,000 square foot Maywood lot, most standard detached additions won’t fit between the required side setbacks. You’ll typically need an attached design: a bump-out off the rear of the house, a second story over the existing footprint, or a garage conversion with living space above it. We verify lot width against current zoning before sketching plans, so you don’t pay for a design the city will reject. Call (626) 657-5461 and we’ll check your lot dimensions during the free estimate.
Opening a 1930s Maywood home for an addition typically triggers upgrades to the electrical panel, the wiring inside the affected walls, and the structural framing where new loads connect. You may also need foundation anchorage bolts and insulation meeting current Title 24 standards. We scope these permit-triggered upgrades during the planning phase and write them into your contract as a material allowance, with any surprises priced and approved in writing before work continues.
Yes. Maywood garages built in the 1920s through 1950s were often constructed on thinner slabs with shallow footings and undersized rafters. A structural evaluation tells us whether the existing slab and walls can carry the load of a finished living space, and whether a second story is even possible. We include this evaluation at the start of every Maywood garage conversion and garage addition. Call (626) 657-5461 to schedule one.
Maywood requires covered parking replacement when a garage is converted or repurposed for living space, even if you’re building above it. We design a compliant carport, tandem parking pad, or angled space that fits the remaining lot width and meets the city’s current parking code. This is resolved during the planning phase, so your permit application doesn’t stall and your budget doesn’t absorb a late change order.
Maywood’s older wood-framed bungalows were built with minimal insulation and often have flat or low-slope roof sections that pond water during winter rains. When we tie a new addition into those walls and rooflines, we address moisture control at the connection points and add insulation that meets current code. Skipping this step means the new addition inherits the old house’s drainage problems. We don’t skip it.
