Mapped street waivers are specialized applications considered by NYC BSA when a Department of Buildings (DOB) objection invokes General City Law (GCL) §35 or §36. These provisions can affect permission to build because of the relationship between a proposed building, an officially mapped street, and the legal means of access.
A waiver does not itself map or open a street, resolve every property access issue, or authorize immediate construction. Start with the actual DOB objection, zoning and street maps, survey, and legal description of the site.

GCL §35 concerns circumstances where a proposed building is located within the bed of an officially mapped street. GCL §36 concerns certain situations where a proposed building lot lacks the required mapped-street relationship for access.
BSA §1-06.1 places qualifying mapped-street waiver applications on the Appeals Calendar (A), following an appropriate DOB objection. The standards and involved agencies depend on whether the case falls under §35 or §36.
A survey or proposed building footprint may show that part of the work is in land reserved by the City street map. DOB may issue an objection that requires examination of BSA waiver eligibility.
The lot may not be on a mapped street or the mapped street may not provide the necessary access. The legal and physical access situation must be documented with current maps and survey materials.
A boundary disagreement, easement issue or unrelated street-opening question may require separate legal or agency review rather than Board relief.
Under BSA §1-06.3(b), a GCL §35 or §36 waiver application must generally be filed within 30 days of the DOB objection. Because that period is triggered by a particular document, applicants should preserve its issuance date and confirm all prerequisites immediately.
Mapped street waivers should be tied to the actual DOB objection and the governing General City Law section. A survey that clearly shows the mapped street line, proposed building footprint or access issue helps distinguish a statutory waiver case from an ordinary street-opening or private-access question.
The application typically needs a current A form, site documents, related DOB correspondence, project drawings and owner authorization as applicable.
For mapped street waivers, SLK Buildings can help collect surveys, DOB objections, plan versions and correspondence for the project team. Mapping, access, property-rights and code determinations remain with the responsible agencies and qualified professionals.
BSA rules address service on DOB, the affected community board and borough president. For §35 filings, BSA forwards materials to DOT, DEP and FDNY for review; for §36, materials are forwarded to FDNY.
These agency reviews can raise access, emergency response, street infrastructure, drainage or other public-interest concerns. The case then proceeds through applicable BSA examiner review, notice, hearing and decision steps.
An approved waiver may address a particular statutory objection; it does not eliminate the need for DOB approvals, surveys, safe emergency access or other municipal permissions. Conditions in the written Board resolution must be reflected in later project documents.
Even approved mapped street waivers do not by themselves clear title, change the City Map or issue a building permit. Owners should document remaining agency review and access questions before committing to construction work or representing the development as fully permitted.
Where the city street map, title documents or physical road condition are uncertain, a land surveyor and qualified legal professional may be essential to determine how the property rights and statutory restrictions interact.
For mapped street waivers, assemble the DOB objection citing the applicable General City Law provision, the filed street map, survey and proposed development drawings. These materials help establish the precise mapped-street condition under review.
Each BSA application is site- and fact-specific. Review the controlling legal provision and all current rules before deciding the procedure, deadline, professional scope or project commitments. An existing DOB objection, BSA resolution or tentative design concept is not itself evidence that the requested relief will be granted.
Future tenants, lenders and contractors may rely on the result. Keep written advice, application records, approved plans and resolution conditions together, and escalate significant legal exposure or uncertain eligibility before making binding project promises.
For coordination assistance, contact SLK Buildings with the property address, borough-block-lot where available, agency notices, relevant drawings and any prior BSA resolution. A focused initial document review helps identify the responsible agency and appropriate next step.

Seeking Professional Guidance on NYC BSA Variances, Appeals, and ComplianceThe New York City Board of Standards and Appeals (BSA) considers qualifying zoning variances, special permits, appeals of certain final agency decisions, and matters involving earlier BSA grants. Owners should identify the property, specific issue, and applicable approval category before filing.
BSA matters may intersect with DOB permits, DCP zoning and land-use procedures, CEQR environmental review, and community-board input. BSA approval does not replace DOB permits, and open violations or preliminary objections do not automatically qualify for BSA appeals.
SLK Buildings assists with BSA records research, application coordination, zoning and code consulting support, agency follow-up, professional submissions, review of prior resolutions, and related multi-agency filings within its confirmed scope of services.
Whether considering relief, preparing for a hearing, or reviewing an existing grant, accurate records and clear next steps help coordinate the required approvals.
SLK Buildings provides free educational content on BSA variances, special permits, appeals, filing requirements, hearings, and resolution conditions. These resources help property owners, business operators, developers, architects, contractors, and project teams distinguish BSA matters from related DOB, DCP, and other agency responsibilities.
For those who prefer professional assistance, SLK Buildings is available to coordinate BSA records review, filing-path research, application documentation, agency comments and follow-up, hearing-related materials, design-professional coordination, prior grant research, and connected NYC agency obligations. Final determinations and regulated professional work remain with the appropriate agency and qualified providers.
