Contractor’s License: B-842038ADU Builder in Temecula, CA
Detached ADUs, garage conversions and junior ADUs built to California code in Temecula, Murrieta and Southwest Riverside County.
An accessory dwelling unit adds usable square footage to your property, generates rental income, or houses family members on the same lot as your primary home. California’s ADU laws (AB 68, AB 881, SB 9) make permitting faster and more predictable than ever, and Temecula and Murrieta have streamlined their plan review timelines to match. A permitted ADU also increases your home’s appraised value because it counts as legal living space.
Woollard Construction builds three types of ADUs in Temecula and the surrounding area:
- Detached ADUs — Standalone units up to 1,200 square feet built in your backyard. Best for maximum privacy, rental income potential and resale value.
- Garage conversions — Convert an attached or detached garage into a code-compliant ADU. Typically the fastest and most affordable path to a permitted unit.
- Junior ADUs (JADUs) — Up to 500 square feet built within the existing footprint of your primary home. Ideal for aging parents or adult children.
Every ADU we build in Temecula or Murrieta includes full architectural plans, structural engineering, Title 24 energy compliance, permit submittal to Temecula or Murrieta planning departments, and construction through final inspection. Most projects take 4 to 6 months of construction time after permits are issued. Permitting typically adds 2 to 3 months on the front end.
ADU pricing in Temecula and Murrieta ranges from $180,000 for a basic garage conversion to $400,000 or more for a fully detached unit with premium finishes. The biggest cost drivers are square footage, site conditions (utilities, grading, foundation type), and finish level. We provide fixed-bid estimates so you know the total cost before signing.

Bathroom Remodeling in Temecula and Murrieta
Full bathroom remodels with custom tile, walk-in showers, vanities and plumbing upgrades. Fixed-bid pricing from $15,000 to $35,000.
A bathroom remodel is one of the highest-ROI home improvements you can make in Temecula. Updated bathrooms recover 60 to 70 percent of project cost at resale and improve daily quality of life immediately. Most Temecula and Murrieta homes built in the 1990s and early 2000s have original bathrooms with dated tile, builder-grade vanities, and inefficient layouts that benefit from a full remodel.
Our bathroom remodeling services in Temecula include:
- Custom tile work — Floor tile, shower walls, decorative accents, niches and herringbone or chevron patterns
- Walk-in showers — Curbless showers, frameless glass enclosures, multiple shower heads and bench seating
- Vanities and countertops — Custom and semi-custom vanities, quartz and natural stone countertops, undermount sinks
- Bathtub installation and replacement — Soaking tubs, freestanding tubs, tub-to-shower conversions
- Plumbing upgrades — Replace galvanized pipes, relocate fixtures, upgrade to PEX or copper
- Electrical and lighting — Recessed lighting, vanity sconces, exhaust fans, GFCI outlets, dedicated circuits
- Heated flooring — Radiant electric floor heat for tile installations
- Accessibility modifications — Walk-in tubs, grab bars, curbless showers, ADA-compliant layouts
Bathroom remodels in Temecula and Murrieta typically take 4 to 6 weeks from demo to final walkthrough. Smaller powder room refreshes run 2 to 3 weeks. Larger primary bathroom renovations with structural changes or layout reconfiguration take 6 to 10 weeks.
Bathroom Remodel Cost in Temecula
- Basic refresh ($15,000 to $20,000) — New vanity, toilet, tile floor, paint, mid-grade fixtures. Existing layout stays.
- Mid-range remodel ($20,000 to $28,000) — Tile shower, custom vanity, quartz counters, upgraded fixtures, new lighting.
- Full gut renovation ($28,000 to $35,000+) — Layout changes, walk-in shower with frameless glass, custom tile work, premium fixtures, heated floors.
