Encinitas — Detached ADU
Owner had unused backyard space on a residential lot. We guided them through Encinitas's coastal overlay ADU requirements, coordinated design and permits, oversaw construction, and placed a tenant within 2 weeks of completion. The ADU now generates $4,374/month — managed by Gibraltar alongside the main property.

North County — Duplex Transformation
Underperforming duplex — one unit vacant, other below market. We renovated both units, added an ADU, and repositioned the entire property. Total monthly income went from $3,800 to $11,200. Triple the cash flow with the same owner investment.
How It Works — From Lot to Rent Check
Feasibility Analysis
We assess your lot: zoning, setbacks, utility access, and projected rental income. Free for current management clients. Takes 48 hours.
Design Coordination
We connect you with experienced ADU architects who know San Diego's specific requirements. Studio to 1,200 sq ft — designed to maximize rental value, not just square footage.
Permit Navigation
California ADU law plus city-specific ordinances equals complexity. We guide you through your city's unique requirements. No surprises at the building department.
Construction Oversight
We monitor the build: timeline, budget, quality. We're not the GC — but we protect your interest throughout construction. The same person who manages the finished unit.
Tenant Placement
Once built, we screen and place a quality tenant — typically within 2 weeks of certificate of occupancy. Professional photography, MLS listing, full background screening.
Ongoing Management
The ADU is managed alongside your main property. One manager, one statement, one point of contact. ADU clients receive a management fee discount.
ADU Rules by City
Every city in San Diego County allows ADUs — but the rules vary. Here's what to know for the cities we serve:
Carlsbad has adopted California's AB 68/SB 13 ADU provisions. Most residential lots qualify for at least one ADU. We guide owners through Carlsbad-specific setback and height requirements.
Encinitas has coastal zone overlay rules that affect ADU setbacks on properties west of I-5. Gibraltar navigates this for owners.

Why no other PM company offers this
Property management companies manage properties. Construction companies build them. Nobody does both — because it requires licensed real estate expertise and construction knowledge under the same roof.
Andrew Piretti has a BS in Civil Engineering, an MBA, and 54 years in San Diego real estate. He's managed properties while they were being built. He understands foundations, setbacks, and tenant screening equally well.
That's why Gibraltar can take you from "should I build an ADU?" to "your tenant moved in last Tuesday" — and manage it forever after. One team, one phone call, one relationship.
