Why Lake Elsinore Homeowners Choose Woollard Construction
35 years in construction, 21 in this valley
Spencer started in construction in 1990. Woollard has built in the Temecula Valley since 2004. More than 350 completed projects. We have graded enough hillside pads in this county to price one accurately.
Site work in the original number
The reason Lake Elsinore quotes come in low and finish high is site work. Grading, retaining, drainage, and engineered foundations get left off the proposal and appear later as change orders. We survey the pad first and put those costs in writing before you sign. More about the company.
One point of contact
Spencer walks your property, measures the setbacks, checks the slope and the drainage path, and stays on the job through final sign off. See what past clients say.
ADU Construction in Lake Elsinore, CA
An accessory dwelling unit puts a second legal home on your lot. Rental demand here is real, and lot sizes in the older neighborhoods support full detached units. See our full ADU services.
Detached ADUs
California allows up to 1,200 square feet detached. Separate entrance, separate utilities, no shared walls, highest rent. On a flat pad this is straightforward. On grade it needs a soils report and engineered foundation design, which we price before design begins.
Garage conversion ADUs
Rosetta Canyon, Alberhill, and Summerly tract homes have tight side yards where a detached unit will not clear setbacks. A garage conversion works instead. The foundation, roof, and walls already exist, so you add insulation, drywall, plumbing, electrical, HVAC, windows, and an entry door. California prohibits cities from requiring replacement parking for a conversion.
Attached ADUs and junior ADUs
An attached unit shares one wall and costs less than detached because utility runs are shorter. A junior ADU carves up to 500 square feet out of your existing floor plan with its own entrance and a small kitchen. JADUs require owner occupancy. Standard ADUs do not.
What Makes Lake Elsinore Projects Different
Four conditions here that a Temecula quote will not account for.
The city runs a Permit Ready ADU Program
Lake Elsinore keeps pre-approved ADU plans on file through the Planning Division at 130 South Main Street. Choosing a pre-approved plan cuts plan check time and design cost. The plan has to fit your lot, which is what the first site visit determines. We compare that route against a custom set and tell you which one saves you more.
Slope drives cost more than square footage
Tuscany Hills, Canyon Hills, and Country Club Heights sit on grade. A detached ADU on a sloped pad needs a soils report, engineered foundation work, retaining, and a drainage plan. That cost is labor and engineering, not materials, and it separates a real quote from a low one.
Flood zone rules apply near the lake
Lakeland Village and the lakefront parcels sit in mapped flood zones. Structures there face elevation requirements and different foundation details. This does not stop a project. It changes the design. We pull the flood map on your parcel before drawing anything.
Drainage is not optional here
Water running off a hillside lot has to go somewhere, and a new structure changes the path. A drainage plan protects your foundation and your neighbor's. Skipping it creates a problem that surfaces during the first heavy winter.
What a Hillside ADU Actually Costs You in Site Work
Lake Elsinore homeowners get two quotes for the same detached ADU and the numbers differ by fifty thousand dollars. The gap is almost always site work, and the low quote is the one hiding it.
The soils report comes first
A sloped pad needs a geotechnical report before an engineer will stamp a foundation design. The report tells you the bearing capacity, the expansion potential of the soil, and whether you need caissons, a deepened footing, or a standard slab. Skipping this step means an engineer designs blind or a plan checker rejects the submittal.
Retaining and grading are separate line items
Cutting a level pad into a slope creates a cut face and a fill face. One or both usually need a retaining wall. Anything over four feet in height needs its own engineering and permit. This is real construction cost and it belongs in the proposal, not in a change order.
Drainage protects your foundation and your neighbor
A new pad changes where water goes during a storm. A drainage plan routes it away from both foundations and off the property legally. Lake Elsinore inspectors look at this closely because the terrain makes it matter.
Utility runs get longer on big lots
A detached unit 80 feet from the main house needs an 80 foot trench for water, sewer or septic, and electrical. On rock or hardpan that trench costs more per foot. We measure the run on the first visit.
Bathroom Remodeling in Lake Elsinore
Lake Elsinore incorporated in 1888 and holds housing stock from nearly every decade since. Lakeland Village carries older cottages and mid century homes with original plumbing. Rosetta Canyon and Canyon Hills tract homes from the 2000s are now hitting the age where builder grade finishes fail. See our bathroom remodeling work.
Full bathroom remodels
We take the room to the studs. On older homes we check supply lines and drains during demolition and tell you what needs replacing before we close walls. You approve tile, fixtures, vanity, lighting, and layout before demolition starts. Most run three to five weeks.
Walk-in shower conversions
Pulling 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 carry weight.
What we protect while we work
We contain the work area, protect flooring on the path in and out, and clean daily. The rest of your house stays usable.
Room Additions and Loft Builds
A room addition extends your footprint. A loft addition builds space above your existing floor plan, which is often the better answer on a sloped Lake Elsinore lot where expanding outward means retaining walls. Both need structural engineering, permits, and inspection.
Lake Elsinore Permits and Approvals
The Planning Division sits at 130 South Main Street and can be reached at 951-674-3124. Elsinore Valley Municipal Water District handles water and sewer.
State law sets the ADU baseline regardless of city: 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.
Hillside parcels add a soils report and grading permit to the package. Flood zone parcels add elevation certification. We handle all of it, including every plan check correction.

Estimated costs. Every property is different, so your final price depends on your lot, design, and finish selections. We give you a firm number after a free site visit.
Site work is what separates a Lake Elsinore quote from a Temecula quote. Grading, retaining walls, soils reports, and engineered foundations add real cost on grade. We itemize that separately so you see exactly what the terrain is costing you. See our full ADU cost breakdown.

What Temecula Valley homeowners say
More than 350 completed projects in Southern California and the Temecula Valley, and a five star rating across Google, Yelp and Houzz.
“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.”
Usually yes. You need a soils report and engineered foundation design. The added cost is site work, not the unit itself. We give you that number before you commit to design.
Yes, on two fronts. You skip most custom design fees and you move through plan check faster because the design has already cleared review. The plan has to fit your lot, which the first site visit determines.
Elevation and foundation requirements change. The project still happens. We pull the flood map for your parcel before drawing anything so the design accounts for it from the start.
A detached ADU runs four to seven months of construction after permits are issued. Slope and site work extend the front end. Garage conversions move faster on both ends.
We serve Lake Elsinore, Wildomar, Murrieta, Menifee, and Temecula from one office. License B-842038. Call (951) 551-6165 for a free site visit.
No, not for a standard ADU. California removed that requirement for standard ADUs permitted after January 1, 2020. Junior ADUs still require the owner to live in the main house or the JADU.
