When you hire SLObispo Remodelers, you're not handing your home off to a rotating cast of subs. The same in-house team handles your project from the first phone call through the final walkthrough: co-owners, project lead, interior designer, project manager, and crew.


We've built our team around reliability and accountability. One designer making your selections, one project manager running your jobsite, one point of contact keeping you in the loop. That's why our projects finish on schedule, on budget, and without the surprises homeowners have come to expect from remodeling.

Transparent Pre-Construction

Transparent Pre-Construction

Before construction begins, we run a structured pre-construction phase: architectural plans, engineering, interior design, selections, and accurate pricing. The estimate you approve is the price we build to. If unforeseen delays or added structural work comes up during the project, our manager will talk you through the situation and come up with a game plan for how to best reduce any added costs and delays. Our team's goal is to keep your project on budget and on time.

FROM FIRST CALL TO FINAL WALKTHROUGH

FROM FIRST CALL TO FINAL WALKTHROUGH

FROM FIRST CALL TO FINAL WALKTHROUGH

Every project we take on follows the same four-phase process. It's how we deliver on time, on budget, and without surprises.

Phase One

Phase One

CONSULTATION & IN-HOME ASSESSMENT

We start with a phone call to understand your scope, timeline, and budget, then schedule an in-home visit. Our estimator walks the space with you, assesses the site, and provides a working price range so you know what to expect before committing to design.

Phase Two

Phase Two

PRE-CONSTRUCTION PACKAGE

Once you're ready to move forward, we open the pre-construction phase: architectural plans, engineering, interior design, material selections, layouts, and 3D renderings. By the end of this phase, you have a complete design and an accurate construction estimate. For projects that require permits, we manage the full submission and approval process with the city and county.

Phase Three

Phase Three

PERMITTING & CONSTRUCTION

Additions and ADUs almost always require permits. We manage the full submission and approval process with the city and county, including planning department review. Once permits clear, our in-house crew handles the build, coordinating every trade, managing all inspections, and keeping your home as livable as possible throughout the project.

Phase Four

Phase Four

FINAL WALKTHROUGH

We walk the finished space together, address every item on the punch list, complete final permit sign-off where applicable, and document the finished project. You get the home you signed up for, fully built, fully cleaned, fully done.
