ADU Advisory
Build it. Rent it. We manage it.
Accessory Dwelling Units are the single biggest opportunity for San Diego property owners to increase income. Gibraltar handles the entire ADU journey — from feasibility analysis through construction to long-term rental management. No other property manager in San Diego offers this.
What's Included
Feasibility Analysis
We assess your property for ADU potential: lot size, zoning, setbacks, utility access, and projected rental income. Free for current management clients.
Design Coordination
We connect you with experienced ADU architects and designers who know San Diego's specific requirements. From studio to 1,200 sq ft — designed to maximize rental value.
Permit Navigation
California ADU law + city-specific ordinances = complexity. We guide you through Carlsbad, Vista, Encinitas, and every 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. Same person who'll manage the finished unit.
Rental Management
Once built, we place tenants and manage the ADU alongside your main property. ADU clients get a management fee discount — building the unit with us creates a long-term partnership.

Frequently Asked Questions
Can I build an ADU on my property?
+
Most residential lots in San Diego County qualify for at least one ADU under current California law (AB 68/SB 13). Specific requirements vary by city — we assess your lot for free.
How much does an ADU cost to build?
+
Typical range: $150,000 to $350,000 depending on size, finishes, and site conditions. At current San Diego rents ($1,800-$2,500/month for a studio/1-bed ADU), payback period is typically 6-10 years.
Do ADU clients get a discount on management?
+
Yes. ADU clients who build with our guidance receive a discounted management rate on the ADU unit. We view it as a long-term partnership — the ADU creates ongoing management revenue for both of us.
What cities have the best ADU opportunities?
+
Every city in San Diego County allows ADUs, but rules vary. Carlsbad, Vista, Escondido, and San Marcos tend to have the most straightforward processes. Coastal cities like Encinitas have additional overlay requirements. We know them all.
