ADU Consulting Services
An ADU is one of the most powerful moves a California homeowner can make — a second home for family, a long-term rental, or a genuine boost to resale value. But the rules, the numbers, and the paperwork are where most projects stall. Big House Real Estate walks you through every stage, from the first feasibility question to the day your unit is ready to live in.
What an ADU can do for you
Accessory Dwelling Units — granny flats, casitas, garage conversions, backyard cottages — have become a cornerstone of housing in San Diego County. State law has steadily cleared the way, and for many homeowners an ADU pencils out better than a move-up purchase. The question is rarely whether; it is how, and how much.
Rental income
A well-placed unit can offset a meaningful share of your mortgage, or become a standalone income property on land you already own.
Multi-generational living
Give aging parents independence while keeping them close, or give adult children a real start without leaving the property.
Property value
A permitted ADU adds durable, appraisable square footage — and makes your home far more compelling to a future buyer.
Why homeowners work with Big House
Local expertise
We know Vista, Oceanside, Carlsbad, Escondido and San Marcos zoning from the inside — what each city allows, and where the friction hides.
End-to-end guidance
Feasibility, design, permits, construction oversight and final support, coordinated by one team so nothing falls through the cracks.
Honest numbers
Clear cost ranges and realistic return projections up front, so you can decide with confidence instead of hope.
Trusted network
Architects, contractors and lenders we have actually worked with — not a list of names, a team that shows up.
How the process works
-
Initial consultation
We start with your goals and your property. What do you want the unit for, and what does the lot actually support? This sets the whole plan in motion.
-
Feasibility study
A detailed look at lot size, set-backs, zoning, utilities and design options — confirming what is possible before you spend on drawings.
-
Design & permitting
We shape a layout that fits how you live, then handle the drawings and permit submissions so the approval process moves smoothly.
-
Construction management
We coordinate vetted contractors, track the schedule and budget, and keep you updated at every milestone — no surprises.
-
Completion & support
Once your unit is finished we stay reachable for questions, adjustments and the small things that come up after move-in.
