Home Remodeling Contractors in Murrieta, CA: Bathroom, Kitchen, Addition or ADU?
Most calls we get from Murrieta homeowners don't start with "I want an ADU." They start with "the bathroom is falling apart," "we need one more bedroom," or "my mom is moving in." The right answer might be a remodel, an addition, a garage conversion — or an ADU. Here's how we help you decide, and what to check before you hire any home remodeling contractor in Murrieta, CA.
Four ways to get more out of a Murrieta house
Bathroom or kitchen remodel — same footprint, better house
If the layout works and you simply need the space to be modern, safe and durable, a remodel is the fastest path. Bathroom remodels in Murrieta typically don't change the structure, so permitting is lighter — but you still need permits for plumbing, electrical and anything touching the shower or tub enclosure, and inspections through the City of Murrieta Building & Safety. Expect a few weeks of construction for a full bathroom and longer for a kitchen with layout changes.
Best for: homes in Bear Creek, California Oaks and Alta Murrieta built in the 1990s and 2000s that are structurally sound but dated. Watch for: contractors who quote a bathroom remodel without opening a wall — water damage behind 25-year-old tile is the most common surprise in the valley.
Room addition — more square footage, same address
An addition adds a bedroom, primary suite, office or family room to the existing house. It needs architectural drawings, structural engineering, a City of Murrieta permit, and often HOA architectural review in communities like Greer Ranch, Spencer's Crossing, Copper Canyon and Central Park. Additions are more expensive per square foot than a remodel because you're building foundation, framing, roof and exterior — but you keep one house, one kitchen and one tax parcel.
Best for: families who need space connected to the main living areas. Watch for: setbacks and lot coverage limits; some Murrieta lots simply don't have room to push outward.
Garage conversion — the quiet middle option
Converting an attached garage into living space is the lowest-cost way to add a bedroom or a junior ADU (JADU, up to 500 sq ft inside the existing footprint). No new foundation, no new roof. On this site we quote garage conversions at roughly $60K–$120K depending on plumbing, insulation, windows and finish level. Murrieta does not require replacement parking when a garage is converted to an ADU, which removes the objection most homeowners expect.
ADU — a separate home with separate income
A detached or attached accessory dwelling unit is its own residence with a kitchen, bath and entrance. It's the right call when the goal is rental income, true privacy for a parent or adult child, or long-term flexibility. In Murrieta a turnkey permitted ADU runs roughly $120K–$200K attached and $200K–$320K detached (up to 1,200 sq ft), with 6–9 months from contract to keys for a detached build. The City's Pre-Approved ADU Program (IB-113) can shorten plan check and lower design costs.
How to decide — three questions
- Who will use the space, and do they need their own kitchen? A kitchen is the line between an addition and an ADU — legally, financially and in terms of resale.
- Do you want rental income? Only an ADU or JADU can be rented as a separate unit (30+ day rentals in Murrieta). An addition can't.
- What does the lot allow? Side and rear setbacks for ADUs are 4 feet; additions follow the underlying zoning setbacks, which are larger. A free feasibility check on your parcel answers this before any design money is spent.
What to check before hiring home remodeling contractors in Murrieta
- CSLB license, active and correctly classified. Class B General Building covers remodels, additions and ADUs. Verify at cslb.ca.gov. Full Circle Builders Inc. is #1009685 (B and C-53).
- Who self-performs the work. Our crew handles concrete, masonry, framing, finish carpentry and painting in-house. Fewer subs means your bathroom isn't sitting half-demoed waiting on a tile sub.
- An itemized quote with allowances. Cabinets, counters, tile and fixtures should be line items, so an upgrade is a known number, not a surprise.
- Permits pulled in the company's name. If a contractor asks you to pull an owner-builder permit, they're shifting liability to you.
- A written warranty on workmanship, and a phone that gets answered after the final check clears. That's where our name comes from.
Living through a remodel in Murrieta
For occupied-home projects we build dust walls, keep working hours predictable, clean daily and keep one bathroom functional whenever the layout allows. For additions and ADUs, most of the heavy work happens outside the existing house — the disruptive weeks are the tie-in at the end. Ask any contractor how they'll protect your home before you ask what they charge.
