How Albany Handles Accessory Structures: A Practical Guide

Albany maintains 58 local ordinances across all categories, and 6 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Albany falls on the strict-to-permissive spectrum compared to other cities.

ADU Rules

Albany allows Accessory Dwelling Units (ADUs) as an accessory use in many residential districts under the Unified Sustainable Development Ordinance (USDO), Chapter 375 of the City Code. The USDO sets where ADUs are permitted, size and design limits relative to the principal dwelling, parking treatment, and the requirement that the ADU comply with the NY State Building Code. ADU construction also triggers a building permit and, when offered for rent, a Residential Occupancy Permit under Chapter 231.

Key details: Authority: Authority: City of Albany Code Chapter 375 — Unified Sustainable Development Ordinance. Adus Permitted As: ADUs are permitted as an accessory use in many residential and mixed-use. Adu Must Be: ADU must be subordinate to the principal dwelling — size and bulk. Compliance With Ny: Compliance with the NY State Uniform Fire Prevention and Building Code is. Building Permit From: Building permit required from the Department of Buildings & Regulatory Compliance.

Building, converting, or operating an ADU without complying with USDO Chapter 375 — including building without a permit, exceeding the size or bulk limits for accessory uses, locating an ADU in a district where it is not permitted, or renting the ADU without a Residential Occupancy Permit under Ch. 231 — is a zoning violation. The Department of Buildings & Regulatory Compliance may issue stop-work orders, citations, and orders to abate, and the City may pursue civil penalties under the USDO's enforcement article and the general penalty provisions of the City Code. Continued violations after notice may also be referred to the Corporation Counsel.

ADU Impact Fees

New York is not a development impact fee state in the California or Washington sense; the Legislature has not enacted a general municipal impact fee enabling statute. Localities derive site-specific exaction authority from State Environmental Quality Review Act (SEQRA) findings and subdivision/site plan review, but flat per-unit residential impact fees are rare and legally constrained. Albany charges building permit fees, plan review fees, and utility connection charges, but no separate parks, transportation, or school impact fees on ADU construction.

Key details: Impact Fee Authority: None statewide in New York. Key Precedent: Albany Area Builders v. Guilderland (1989). Accessory Structure Permit: ~$50-$100 (Albany Fee Chart). Building Code: 19 NYCRR 1219. School Impact Fees: Not authorized in NY.

Failure to pay permit fees blocks issuance of the building permit and certificate of occupancy. Unpermitted construction to avoid fees: stop-work order under USDO §375-5, double permit fees on after-the-fact applications, and exposure of concealed work for inspection. Unpaid Albany Water Department tap fees become a lien on the property and can be certified to Albany County for collection on the tax roll. Inaccurate cost-of-construction valuations on permit applications expose the homeowner to enforcement under New York Penal Law 175.30 (false written statement) if egregious.

Albany is more permissive than most cities when it comes to adu impact fees. That said, there are still limits.

ADU Owner Occupancy

The Albany USDO (Chapter 375), as amended September 8, 2025, explicitly requires the property owner of any lot containing an accessory dwelling unit to occupy either the primary or accessory dwelling unit as their primary residence and to certify such occupancy biennially with the Department of Buildings and Regulatory Compliance. This is one of the most explicit owner-occupancy mandates among New York mid-sized cities and materially constrains pure investor conversion. The use is also restricted to lots with a single-unit dwelling, and no more than two dwelling structures may be permitted on the lot.

Key details: Owner-Occupancy: Required by USDO (one of two units). Certification Cycle: Biennial (every 24 months). Certifying Authority: Dept. of Buildings & Regulatory Compliance. STR Cap: No <30-day rentals either unit. State Preemption: None (New York home rule).

Renting both the primary and accessory units without occupying either as primary residence: USDO violation under §375-5 with civil penalties, possible revocation of the ADU use approval, and conversion of the lot to non-conforming status. Failure to file biennial owner-occupancy certification: notice of violation, civil penalties accruing per day uncured, and potential nullification of the ADU permit. False certification: USDO enforcement plus potential New York Penal Law 175.30 prosecution. Operating either unit as a short-term rental: separate violation of the express less-than-30-day prohibition with citations and possible court-ordered injunction.

This is one of the stricter rules in Albany's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

ADU Permits

The City of Albany's Unified Sustainable Development Ordinance (USDO), codified as Chapter 375 of the Albany Code, was amended by the Common Council on September 8, 2025 to permit accessory dwelling units (ADUs) as a use accessory to a single-unit dwelling. An ADU is capped at 800 square feet of gross floor area, no more than two dwelling structures may be permitted on a single lot, and the property owner must occupy either the primary or accessory unit as a primary residence with biennial certification to the Department of Buildings and Regulatory Compliance. Construction is governed by the New York State Uniform Fire Prevention and Building Code (19 NYCRR 1219, adopting the 2020 IRC/IBC/IFC).

Key details: Code Authority: USDO Chapter 375 (eCode AL0951). ADU Adopted: Common Council Sept. 8, 2025. Max ADU Size: 800 sq ft gross floor area. Owner Occupancy: Required, biennial certification. STR Prohibition: No <30-day rentals on lot.

Constructing an ADU without USDO use approval and a building permit: stop-work order from the Department of Buildings and Regulatory Compliance, double permit fees on after-the-fact applications, exposure of concealed work for inspection, and possible order to remove non-compliant construction. USDO violations are enforceable under §375-5 (Administration and Enforcement) with civil penalties and injunctive relief in Albany County Supreme Court. Failure to file the biennial owner-occupancy certification voids the ADU permit and subjects the unit to enforcement as an unlawful third dwelling. Operating the unit as a short-term rental violates the express less-than-30-day prohibition in the ADU use standards.

ADU Rental Restrictions

The Albany USDO (Chapter 375), as amended September 8, 2025, expressly prohibits offering either the primary or accessory dwelling unit on a lot containing an ADU for rent by guests for less than 30 consecutive days where the unit is offered for tourist or transient use. Long-term rentals (30+ days) of the ADU are permitted but the property owner must continue to occupy one of the two units, and the rental unit must register with Albany's Rental Dwelling Registry (Chapter 231). New York has no statewide rent control on small one-to-three-unit owner-occupied properties; statewide rent stabilization (ETPA) does not generally apply to Albany.

Key details: Long-Term Rental: Allowed (owner must occupy 1 of 2 units). Short-Term Rental: Prohibited on ADU-bearing lots (<30 days). Rental Registry: Albany Code Chapter 231 (24-month cycles). Tenant Protections: NY HSTPA 2019 + RPL §235-b habitability. Security Deposit Cap: 1 month (NY HSTPA 2019).

Operating either unit as a short-term rental (under 30 days for tourist/transient use): USDO violation under §375-5 with civil penalties, possible cease-and-desist order, and revocation of the ADU use approval. Failure to register a rented unit under Chapter 231 Rental Dwelling Registry: notice of violation, registration fees and penalties, possible inability to lawfully collect rent (potential defense to landlord eviction action in Albany City Court). Failure to maintain owner-occupancy of one of two units while renting: separate violation of USDO ADU use standard. Source-of-income discrimination: New York State Division of Human Rights complaint with possible civil penalties and damages.

Compared to other cities, Albany takes a harder line on adu rental restrictions. The enforcement and penalty structure reflects that.

Shed Rules

Sheds in Albany are regulated as accessory structures under the Unified Sustainable Development Ordinance (USDO), Chapter 375 of the City Code. In residential zoning districts a shed may be no larger than 200 square feet, must be set back at least 2 feet from side and rear lot lines, and must observe the front-yard setback that applies to the principal structure. A City of Albany building permit is required before constructing a new accessory structure or replacing an existing one. New York State separately exempts one-story detached storage sheds 144 sf and smaller from a state building permit under 19 NYCRR §1203.3(a)(1), but that exemption is opt-in by the local code-enforcement program and does not override the local zoning permit Albany requires.

Key details: Maximum shed size: Maximum shed size in residential districts: 200 sq ft (USDO Chapter 375). Minimum 2-foot setback: Minimum 2-foot setback from side and rear lot lines (some minor exceptions. Front setback for: Front setback for the principal structure also applies to the accessory structure. City of Albany: City of Albany building permit required before construction or replacement. State permit exemption:: State permit exemption: 19 NYCRR §1203.3(a)(1) — one-story detached sheds ≤144 sq.

Building or replacing a shed without a permit, or installing one that exceeds 200 sf or violates the 2-foot setback, is a USDO violation enforceable by the Department of Buildings & Regulatory Compliance. Typical enforcement begins with a written notice of violation directing the owner to obtain a permit, modify the structure, or remove it. Continued non-compliance can result in appearance tickets and per-day fines under Chapter 133 (Building Construction) of the Albany City Code and may require the owner to apply for a variance from the Board of Zoning Appeals.

The Bottom Line

Albany is tougher than many cities when it comes to accessory structures. Out of the 6 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Albany, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

Keep in mind that Albany can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
