Absolutely. California’s 2024 ADU laws make it easier than ever to convert garages into rental units. The new regulations eliminated owner-occupancy requirements, so you can rent out both your main house and garage conversion simultaneously. In Lexington’s rental market, converted garage ADUs typically rent for $1,500 to $3,000 per month, depending on size and amenities. To qualify as a legal ADU, the conversion must include proper permits, separate entrance, kitchen facilities, and bathroom. We ensure your conversion meets all requirements for legal rental use.
Most garage conversions in Lexington take 6-12 weeks to complete, depending on complexity and permit approval times. Simple bedroom conversions typically finish in 6-8 weeks, while full ADU builds with kitchen and bathroom can take 10-12 weeks. The timeline includes permit approval (2-4 weeks), construction (4-8 weeks), and final inspections (1 week). Weather, material availability, and change orders can affect timing. We provide realistic schedules upfront and keep you updated on progress throughout the project.
Yes, professional garage conversions typically increase property values by 10-30% in the Bay Area market. The exact increase depends on the quality of conversion, local market conditions, and whether it’s a basic room addition or full ADU. Garage conversions add functional square footage to your home, which directly impacts appraisal values. More importantly, the rental income potential from an ADU conversion can provide ongoing returns that far exceed the initial investment. Many clients see their conversion pay for itself within 3-5 years through rental income.
A basic garage conversion creates additional living space like a bedroom, office, or family room within your existing home. A garage ADU (Accessory Dwelling Unit) creates a completely independent living space with its own entrance, kitchen, and bathroom that can be rented separately. ADU conversions require more extensive permits and construction but offer greater rental income potential and property value increases. Basic conversions are less expensive but can’t be rented as separate units. We help you determine which option best fits your goals and budget based on your specific situation and local regulations.
