A Primary Suite Built Onto Your LA Home
Serving: Los Feliz, Hancock Park, Cheviot Hills, Westchester, Encino, Sherman Oaks, and Altadena.
Los Angeles Home Remodelers designs and builds the primary suite addition Los Angeles couples ask us for most: a quiet bedroom, an en suite bathroom, and a walk-in closet, added off the back or up top. We handle design, engineering, permits, and the build under one contract.
Some people still call it a master bedroom addition. It’s the same project, and it starts with where your sewer line runs and how much floor area your lot has left.
Suites go wrong on the details, so we settle three before anyone draws: how far the bath sits from the sewer line, which walls the closet gets for hanging rods, and what separates your bedroom from the kids’ rooms.
- Sewer line located first
- Closet walls planned for rods
- Sound insulation at shared walls
- Egress window in the bedroom
- Blocking for future grab bars
- Warranty terms in writing [confirm]

Choosing a Primary Suite Contractor in LA
Ask where the new bath will drain before you look at tile. Then check the CSLB license, and confirm it’s a B general license that covers the whole addition, not only the finishes.
Compare bids line by line. A low suite bid often leaves out the sewer connection, the sound insulation, or the closet build-out, then adds them as change orders. Your contract prices every line below up front.
- Site survey and floor-area check
- Framing and roof tie-in

- Sliding door to a private patio
- Footings and foundation
- Sewer and drain connection
- Sound insulation at shared walls
- Curbless shower and membrane
- Walk-in closet shelving and lights

What Working With Us Looks Like
One point of contact
Your project manager runs the survey, design, permits, and build, and answers your calls. You never chase an architect, an engineer, and a framer for three different answers.
Written scope, written changes
Every item in your suite, down to the closet rods and the shower valve, is a line item. Any change gets priced and signed before a crew touches it.
A clean site, every evening
A sealed-off work zone, floor protection inside, and a locked site each night. We tell you ahead of time which days the new wall opens into the house.
Five Parts of a Primary Suite in Los Angeles
Five pieces decide how the suite lives day to day. Settle the bedroom layout and the bath location first, because together they set the footprint and the plumbing run.
Bedroom Layout
Your primary bedroom needs one clear wall for the bed, room to walk both sides, and a window that meets egress rules. We put the suite at the far end of the house, so you reach it without passing the kids' rooms.
En Suite Bath
The en suite bathroom goes where its drain can reach the sewer line with enough slope. That's usually the side of the suite nearest the existing bath or the main line.
Walk-In Closet
A walk-in closet needs long walls more than floor area. Two facing walls of hanging rods with an aisle between them beats a square room with one good wall. We plan lights and outlets inside.
Door to the Yard
A sliding door or a pair of French doors opens the bedroom to a private patio. On a slab ranch, we keep the threshold low for a no-step exit. We also check the setback, since a door near the lot line changes what neighbors see.
Natural Light
Set bedroom windows high on walls that face the neighbors and low on walls that face your yard. A skylight or clerestory brings natural light into the bath without a view in.
Primary Suite Styles LA Homeowners Choose
Pick a style that matches the rest of the house, so the suite reads as original and not as a box added on.
Calm Minimal
Flat-panel doors, plaster-white walls, and one wood tone. This look suits mid-century and modern homes, and it keeps a smaller suite from feeling crowded.
Warm Wood
White oak floors, wood-slat closet doors, and a wood vanity with a stone top. It fits Craftsman houses, where the new trim can match the original casings.
Spanish Revival Suite
Arched openings, painted tile at the vanity, and wrought-iron hardware. We match the plaster texture and the roof tile, so the addition looks like part of a 1920s Spanish house.
Mid-Century Suite
Wide sliders, a low roofline, and clerestory windows. This look opens a ranch bedroom to the yard, and it’s the easiest style to match on a post-war slab house.
Accessible Ground-Floor Suite
Wide doorways, a curbless shower, and lever handles throughout. It looks like any other suite, but it works for aging in place.
Where Should Your Primary Suite Go in LA?
Your lot and your plumbing decide where the suite goes. Match the location to your yard, your floor-area limit, and how far the new bath sits from the sewer.

Curbless shower
A shower with no curb, a linear drain, and a bench. It’s the easiest shower to use at any age, and in a new addition we set the floor low from the start.
Soaking tub
A deep freestanding or drop-in tub for long soaks. Plan one only if you’ll use it, because it takes floor space a bigger shower or a double vanity could use.
Double vanity
Two sinks with drawers between them, on a wall at least [60] inches long. It ends the morning line at one shared sink.
Undersized water heater
A soaking tub and a second shower can outrun an old tank heater. We check its size early and plan a larger tank or a tankless unit if yours falls short.
What Your LA Home Type Means for a Primary Suite
Your house’s era decides where the suite fits and how the new bath reaches the sewer. Here’s what each type usually allows.
1940s–60s
Single-Story Ranch
Ranches in Encino and Woodland Hills suit a ground-floor suite off the back bedroom hall. The slab means the new drain runs in a trench to the main line, so we locate it with a camera before design.
1980s–2000s
Two-Story Stucco
These homes usually put the suite upstairs, over the garage or a rear bump-out. We stack the new bath above an existing one when we can, which keeps the drain short and the ceilings below intact.
1910s–30s
Craftsman Bungalow
Bungalows in Eagle Rock and Highland Park sit on raised foundations, so the suite’s plumbing runs in the crawlspace. HPOZ review may set the roof pitch and siding [verify].
Any era
Hillside Homes
A hillside suite often steps down the slope below the main floor. If the bath sits lower than the sewer line, it needs an ejector pump, and the Hillside Ordinance limits size [verify].
Any era
One-Bathroom Houses
Adding a primary bath here doubles your bathrooms, so we check the main sewer line, the water heater, and the water pressure first. Old clay or cast-iron lines often get replaced during the work.
Do You Need a Permit for a Primary Suite in LA?
Yes. A primary suite adds floor area, plumbing, and wiring, so LADBS needs plans, plan check, and inspections from footings to final. City Planning rules on floor area and setbacks come first [verify for your zone].
Part of the addition permit
- New floor area and foundation
- Bath drain and sewer connection
- New circuits, lights, and outlets
- Heating and cooling extension
- New exterior doors and windows
Usually permit-free
- Closet shelving and drawer units
- Paint, trim, and door hardware
- Blinds and window coverings
- Mirrors and towel bars
- Furniture, rugs, and bedding
Bedrooms need an egress window
The California Residential Code calls for an emergency escape opening in every sleeping room [verify code section]. We size the bedroom window for it on the first sketch, so the design doesn’t shift in plan check.
Title 24 covers the new suite
California’s Title 24 energy code sets insulation, window, and lighting rules for the addition. A Title 24 report goes in with your plans, and the inspector checks the work before drywall.
Smoke and CO alarms go in too
A permitted addition usually brings interconnected smoke alarms and carbon monoxide alarms through the house [verify]. We wire them into the plan, so the final inspection doesn’t stall on the old hallway.
Why Homeowners Pick Us Over the Lowest Bid
The lowest addition bid in Los Angeles usually leaves out the engineering, the footings, or the roof tie-in. We price the real scope during design, so your change-order column stays close to empty.
- Line-item scope, including footings, framing, and tie-ins
- One project manager answers your calls start to finish
- Materials get ordered only after the permit is issued
- A sealed work zone, so the rest of the house stays livable
- Payments tied to milestones, never to a calendar
- A written workmanship warranty you can hold us to
- Crews who work on our jobs only, not day labor

How Your LA Primary Suite Gets Built
A permitted primary suite runs in six phases. Plan check and inspections set most of the pace, not the carpentry.
Phase 01
Survey & layout
We survey the lot, find the sewer line, and sketch bedroom, bath, and closet options. You pick one layout before we draw the full set.
Phase 02
Design & engineering
We draw the plans, the engineer sizes footings and beams, and you choose tile, tub, and vanity. This phase runs about [6–10] weeks.
Phase 03
Plan check & permit
LADBS reviews the plans and the Title 24 report, often for [8–12] weeks. We answer corrections and order long-lead items like the tub and windows.
Phase 04
Foundation & plumbing
We dig footings, trench the new drain to the sewer, and pour. The city inspects the footings and the underfloor plumbing first.
Phase 05
Framing & rough-ins
Walls, roof tie-in, and windows go up in [3–5] weeks. Rough plumbing, wiring, and sound insulation then pass inspection before drywall.
Phase 06
Finishes & final
Tile, vanity, closet, and doors go in over [5–8] weeks. After final inspection, we open the wall to the house.

Primary Suite Addition FAQs
Click a question to see the answer. The first one is open to start.
How much space do you need for a primary suite addition?
Most suites need a bedroom, a bath, and a closet in one footprint, often around [300–500] square feet. Your floor-area limit and setbacks set the real cap, so we check them in ZIMAS before we sketch anything.
Can I add a primary bathroom to my house?
Usually, yes, if the new drain can reach your sewer line with enough slope. We run a camera through the main line first. If the bath sits too low or too far away, an ejector pump or a new branch line solves it.
Should a primary suite go on the ground floor or upstairs?
Go ground floor if you plan to stay into retirement or want a door to the yard. Go upstairs if your yard is small or you want distance from the street. An upstairs suite also means engineering and a stair.
Does a primary suite addition add value?
It often does, because it adds a bedroom and a bath. We’re builders, not appraisers, so ask a local agent or appraiser to run comparable sales. For tax effects, ask the LA County Assessor about new-construction assessment.
What makes a primary suite work for aging in place?
A ground-floor suite with a no-step entry, a curbless shower, and doorways at least [36] inches wide. Add blocking for grab bars and a shower bench now, even if you won’t need them for years.
How does the plumbing reach a new en suite bathroom?
The new drain ties into your sewer line, either in a trench under the slab or through the crawlspace. Supply lines branch from the nearest main, and the city inspects both before the floor or walls close.
How big should a walk-in closet be?
Plan on at least [5] feet of width for rods on one side, or about [7] feet for rods on both sides with an aisle. Measure your current hanging space, and we’ll size the closet to beat it.
How do you keep the suite quiet from the kids' rooms?
We put sound insulation in the shared walls and ceiling, hang a solid-core door, and use closets between rooms as a buffer. Placing the suite at the far end of the house does the most, so we start there.
Do I need a permit for a primary suite addition in Los Angeles?
Yes. Any addition with a bedroom and bath needs LADBS plan check, a building permit, and inspections. We pull the permit [in our name, confirm], prepare the Title 24 report, and book every inspection through final.
Can we live at home while you build the suite?
Most families do. We build the suite behind a sealed wall and open it into the house near the end. Expect noise on foundation and framing days, and a short water shutoff when the plumbing ties in.
