Doubts
FAQ’s
What makes an accessory apartment "legal" in Long Island?
A legal accessory apartment must be approved by your local town or village. It requires a specific permit, adherence to strict building codes (like fire separation and egress windows), and an official Certificate of Occupancy. TCR Builders handles this entire compliance process.
Can I just rent out my basement without a permit?
No. Renting an illegal apartment in Nassau or Suffolk County can lead to massive fines, forced evictions, and severe liability issues if a tenant gets hurt. We strongly advise—and exclusively build—fully permitted, legal units to protect you and your investment.
Are there zoning restrictions for accessory apartments in my town?
Yes, every town and village in Long Island has its own specific rules. Some require the homeowner to live on the property, while others have minimum lot size or parking requirements. We conduct a full feasibility study to determine exactly what is allowed on your specific property.
Do I need separate utilities for the accessory apartment?
While it depends on local codes, it is highly recommended and often required to have separate electrical sub-panels or meters, as well as dedicated heating controls, so tenants can manage their own usage. We handle all of this specialized plumbing and electrical work.
Will my property taxes go up if I add an accessory apartment?
Adding a second kitchen and legally habitable square footage will likely increase your home’s assessed value. However, the reliable monthly rental income generated typically far exceeds any incremental increase in property taxes, making it a highly profitable long-term investment.
How long does the permitting process take?
Because accessory apartments often require special use permits or zoning board approvals, the paperwork phase can take several months before construction begins. TCR Builders manages this entire timeline and deals directly with the town, keeping you updated every step of the way.
