What We Build in Butterfield
Bathroom remodels
Murrieta housing is concentrated in a narrow build window, which makes the findings consistent. Fiberglass tub surrounds with water tracking behind the seam. Builder grade tile over greenboard with no waterproofing membrane. Cracked grout letting the wall act as a sponge. We take the room to the studs and correct the substrate rather than tiling over the same failure. Most full remodels run three to five weeks.
Walk-in shower conversions
Removing a step-over tub and building a curbless walk-in shower is our most requested bathroom job. We slope the pan for drainage, install slip resistant tile, and block grab bars into the framing so they hold real weight rather than pulling out of drywall. See our tub to shower conversion work.
ADUs
Detached units where the lot allows, garage conversions where it does not, and junior ADUs where you would rather not change the exterior at all.
Room additions and lofts
A room addition extends your footprint. A loft addition builds above your existing floor plan when the lot leaves no room to expand sideways. Both need structural engineering, permits, and inspection.
Which ADU Type Fits Your Lot
The answer here comes down to measurement, not preference.
Detached units need real side yard
California requires four feet from the side and rear property lines and allows up to 1,200 square feet. On a standard Murrieta tract lot, once you subtract the house footprint and both side yards, the buildable area often cannot hold a unit worth building. We measure on the first visit and tell you before you spend on design.
Garage conversions use a footprint you already have
Foundation, roof, and walls are done. You add insulation, drywall, plumbing, electrical, HVAC, windows, and an entry door. California prohibits cities from requiring replacement parking for a conversion, so your driveway stays a driveway.
Junior ADUs avoid exterior work
Up to 500 square feet carved from your existing house with its own entrance and a small kitchen. The lightest permit and review path of the three. JADUs require you to live in the main house or the JADU. See our junior ADU work.
You are allowed one ADU and one JADU on nearly every single family lot in California.
HOA and Association Review
Where an HOA applies to your Butterfield property, state law prevents it from prohibiting an ADU on a single family lot. Architectural standards on exterior materials, colors, and roofing still apply.
Association review comes before the city permit. Submitting to the city first means redesigning the exterior after review and resubmitting, which adds months. We submit to the association first and design to the community standard so the package clears on the first pass.
Tell us which association governs your property on the first visit and we will design to its standards from the start.
Permits in Butterfield
Murrieta incorporated in 1991 and runs its own Building and Safety Division. Water and sewer service comes from Western Municipal Water District, Rancho California Water District, or Eastern Municipal Water District depending on the parcel.
State law sets the ADU baseline: 1,200 square feet maximum detached, 500 square feet for a JADU, four foot side and rear setbacks, a 16 foot height limit for a standard detached unit, and a required decision on a complete application within 60 days. California also requires every city to maintain a program of pre-approved ADU plans, which shortens plan check when one fits your lot.
We submit, handle every plan check correction, and schedule inspections.
Costs in Butterfield
Bathroom cost turns on whether plumbing moves, what demolition uncovers, and tile selection. ADU cost turns on trench distance, panel capacity, and site slope. See our full ADU cost breakdown.
These are estimated ranges. They cover construction and standard finishes. They exclude site plan, permit fees, school fees, and engineering consultants, plus any soils report, grading, trenching, retaining walls, HOA fees, or utility connection fees your property requires.

“As a plumbing contractor I've worked with a lot of builders over the past 25 years and the truly exceptional ones are few and far between. Woollard Construction is one of the best. We routinely go back to homes they've either remodeled or performed additions to years later for general plumbing maintenance or repairs and the homeowners still speak glowingly of their experience with Woollard construction even decades later. There is only ONE home builder I regularly recommend and that is Woollard Construction.”
“Everything about our experience with Woollard Construction was amazing!! Spencer was fantastic!! He was punctual, professional and great at communicating where we were in every step of the process. Our ADU is beautiful and we are so happy with how everything turned out.”
“We received several quotes before going with him, and his price was extremely competitive, especially considering the quality of his work. I was concerned about having the bathroom be an unusable mess during the remodel, but Spencer left it spotless each time he finished for the day. He communicated clearly every step of the way and was prompt and thorough.”
It depends on your side yard after setbacks. We measure on the first visit and tell you honestly rather than selling you a design that will not fit.
Price turns on whether plumbing gets relocated, what we find behind the walls, and your tile and fixture selections. We quote a fixed written scope after the walkthrough.
No. State law prevents an HOA from prohibiting an ADU on a single family lot. Architectural review still covers exterior materials, colors, and roofing.
Three to five weeks for a full remodel. Two to three weeks for a guest bath or powder room. Three to four weeks for a tub to walk-in shower conversion.
